Category: Technology

Technology evolves rapidly, and there’s always something new on the horizon—whether it’s the latest programming framework, cloud service, or infrastructure upgrade. While adopting modern solutions can be beneficial, the reality is that newer doesn’t always mean better for every situation.

Take Ferrari, for example. It’s one of the best cars in the world, but is it the right choice for a school run? Probably not. A more practical car would get the job done with less hassle, cost, and maintenance. The same logic applies to technology: just because something is new and advanced doesn’t mean you need it.

I have often experienced scenarios where using the latest technology might not be the best choice. A lot of companies subscribe to a lot of technology that they don’t need and waste valuable money.

Overengineering with the Latest Programming Techniques

Imagine you’re building a simple to-do list application. You could use the latest programming frameworks, microservices architecture, and AI-powered features to predict tasks. But is all that necessary? For a basic to-do app, a straightforward monolithic architecture with a simple front-end and back-end would suffice. Overengineering with advanced techniques not only increases development time but also adds unnecessary complexity and cost.

If you’re building a simple company website or blog, plain HTML, CSS, and JavaScript (or even a CMS like WordPress) can be more efficient. Using heavy frameworks adds complexity, increases load time, and requires ongoing maintenance for security updates.

I believe in giving time to the new technology to mature before I start implementing it in projects. When KnockoutJS came to the market with a lot of hype, we used it in our projects. Within a few years, the popularity of the KnockoutJS went down, and I found it challenging to find the experts to support those projects.

Cloud Services: When Simplicity Wins

Cloud computing has revolutionized how we build and deploy applications, but not every project requires the latest cloud services. For instance, if you’re running a small blog or a personal portfolio website, you don’t need a high-availability, multi-region cloud setup with auto-scaling and serverless functions. A basic shared hosting plan or a simple virtual private server (VPS) would work just fine.

Serverless computing (like AWS Lambda, Azure Functions) is a great innovation, but is it necessary for every application? If you have a small internal tool that runs reliably on a virtual machine or traditional hosting, switching to serverless can introduce unnecessary costs and complexity. Serverless makes sense for highly variable workloads, but if your system has steady traffic, traditional hosting might be more cost-effective. A simple VM-based or containerized deployment could work just as well. And you can host many tools in one VM.

Kubernetes is the gold standard for container orchestration, but do you really need it for a small business application with just a few users? If you use Kubernetes for small apps, you will require DevOps expertise and additional costs for managing nodes and networking, which is unnecessary complexity when a more straightforward solution would suffice. If your application runs on a single server or has a few containers, a managed container service like AWS ECS or Docker Compose could be simpler and more cost-effective.

Some businesses rush into a multi-cloud strategy, believing it provides better reliability and cost savings. However, managing multiple cloud providers can increase complexity and costs without providing real benefits. If your workload is stable and fits within one cloud provider, it’s often more straightforward and more efficient to optimize for that platform instead of spreading across multiple providers. Multi-cloud is useful when business continuity, compliance, or specific services require it, but not just because it’s trendy.

Databases: Not Every App Needs Big Data

When building an application, it’s tempting to use the latest database technologies like distributed NoSQL databases or real-time analytics engines. However, for many use cases, a traditional relational database like MySQL or PostgreSQL is more than adequate. These databases are reliable, well-documented, and easier to manage for smaller-scale applications. A local library management system doesn’t need a distributed database like Cassandra. A simple SQL database will handle the data efficiently and cost-effectively.

Mobile Apps: Native vs. Cross-Platform

While native mobile app development offers the best performance and access to device-specific features, it’s not always necessary. For many applications, cross-platform frameworks like Flutter or React Native can deliver a great user experience without the need to maintain separate codebases for iOS and Android. However, a small business app for tracking inventory doesn’t need the performance optimization of native development. A cross-platform solution can save time and resources while still meeting the business’s needs.

AI and Machine Learning: Not Every Problem Requires a Smart Solution

Artificial intelligence and machine learning are powerful tools, but they’re not always the right solution. For example, if you’re building a basic chatbot for customer support, a rule-based system might be more than enough. Implementing a full-scale natural language processing (NLP) model would be overkill and could lead to unnecessary costs and complexity. A simple FAQ-based chatbot using predefined responses is often sufficient for small businesses, rather than deploying a complex AI-driven conversational agent.

I am not against the new technology, but I am against the hype. The key to effective technology use is understanding the problem you’re trying to solve and choosing the right tools for the job. Just as you wouldn’t use a Ferrari for a school run, you don’t always need the latest and greatest tech for every application. By focusing on simplicity, cost-effectiveness, and practicality, you can build solutions that are efficient, maintainable, and fit for purpose.

In my experience working with modern web applications, one of the biggest challenges is balancing speed, scalability, and efficiency. No matter how well a database is optimized, as traffic grows, certain bottlenecks start appearing—slow login sessions, delayed dashboard reports, lagging product displays, and inefficient handling of dynamic content. A lot of time, we keep dynamic content in the database with the hope of changing the content when required, but we never need to change the content frequently. In the end, showing the contents from the database increases the DB hit significantly when the traffic increases.

That’s where Redis comes in. The concept is simple, which is putting the frequently used data in place to reduce the DB hit. Over time, I’ve realized that introducing Redis into an application architecture can significantly improve performance and user experience. Whether it’s caching frequently accessed data, improving authentication mechanisms, or optimizing background tasks, Redis has become an essential tool for building high-performance applications.

Let me share some real-world scenarios from my experience where Redis has made a significant impact.

Faster and More Reliable Login Sessions

One of the first places I found Redis helpful was in managing user sessions. If we use stateful (sessions-based) session management for a monolithic application, usually, the server maintains user information(The benefit is using JWC is a different topic). The user data and session information are typically stored on the server, often in a database or memory. This unique session ID is exchanged between the browser and the server with each request, either via cookies or by embedding it in the request URL (less secure). Initially, it will work fine for small traffic but can become a bottleneck as the user base grows. Each login will require reading and writing session data in the database, adding unnecessary load. Scaling across multiple servers means session inconsistencies, as each server has to query the same database. This is where Redis comes in handy. It can store the session data in memory, reducing lookup time significantly. It can handle session expiration without the need for any manual cleanup. With Redis as a centralized session store, all application instances can access the same session data without database hits.

Powering Report Dashboards

Every large web application has some sort of dashboard and Reports. Dashboards that display real-time analytics or reports often require frequent database queries, which can strain the system. Reports involved aggregating millions of records, slowing down the database. Multiple users pulling dashboards/reports at the same time also create locking issues. Also, frequent querying can lead to old data being displayed before the update is completed. Redis can cache this data, reducing the load on the database and ensuring that dashboards load quickly.

In my experience on the reporting dashboard of many platforms, we used Redis to cache frequently accessed data like daily sales, user activity, and inventory levels. This reduced database queries by 80% and allowed the dashboard to update in real time, providing a seamless experience for business users.

Optimizing Product Displays

E-commerce platforms often display product details, reviews, and recommendations. Fetching this data from a database for every request can be slow and resource-intensive. Redis can cache product data, ensuring that pages load instantly. For an online voucher shop, we implemented Redis to cache product details and recommendations. This reduced page load times from 3-4 seconds to under 500 milliseconds, significantly improving the user experience and boosting conversion rates.

Storing Dynamic Content Efficiently

Web applications often serve dynamic content like user-generated posts, comments, or notifications. Storing and retrieving this content from a database can be slow, especially as the application scales. Redis can act as a high-performance data store for such dynamic content. In our employee engagement platforms, we used Redis to store and retrieve user posts and comments. This allowed us to serve content to users in real time, even during peak traffic periods, without overloading the database.

Queueing Background Jobs

Web applications often need to handle background tasks like sending emails, processing payments, or generating reports. Redis can be used as a message broker to queue and manage these tasks efficiently. In some projects that required sending bulk emails to users, we used Redis to queue email jobs. This allowed us to process thousands of emails in the background without affecting the performance of the main application.

Caching Frequently Accessed Data

Redis is an excellent tool for caching frequently accessed data, such as configuration settings, user preferences, or static content. This reduces the need to query the database, improving overall performance repeatedly. In some content management side of some systems, we used Redis to cache website settings and user preferences. This reduced database load and ensured that the application remained fast and responsive, even as the number of users grew.

Redis is more than just a caching tool; it’s a versatile and powerful solution that can address a wide range of challenges in modern web applications. After integrating Redis into multiple areas of our system, it became one of the most essential tools in our tech stack. If you’re building a web application and haven’t yet explored Redis, I highly recommend giving it a try. Its simplicity, speed, and flexibility make it a must-have tool for any developer looking to deliver high-performance, scalable, and user-friendly applications. Redis isn’t just an option—it’s a game-changer.

Migrating from one dedicated hosting provider to another is a complex task that requires careful planning. Whether you’re moving to a new data center or a different hosting provider, missing even a small step can lead to downtime, data loss, or performance issues. Based on my experience handling multiple hosting migrations, I’ve compiled this comprehensive checklist to help ensure a smooth transition.

Planning

✅Document existing server configurations, applications, and dependencies.
✅Ensure the new hosting environment supports your software stack, OS, and required services.
✅Take full backups of databases, applications, and configurations before starting the migration.
✅Notify stakeholders about potential downtime and plan for minimal disruption. ✅Notify clients or managed partners for a plan to add the new IP address for any whitelisting.
✅Ensure that the new hosting provider meets your security and compliance requirements.

Infrastructure Preparation

✅ Configure the new hosting environment, including OS, storage, and networking.
✅ Set up web servers (IIS, Apache, Nginx), databases, security tools, and dependencies.
✅ Ensure firewalls, DDoS protection, and security policies match the old setup.
✅ Install and configure SSL/TLS certificates to avoid security warnings.
✅ Maintain access control for applications, services, and databases.

Data Migration

✅ Use database replication or backup/restore methods to transfer SQL, NoSQL, or other databases.
✅ Copy all web application files, configurations, and static content to the new server.
✅ Update environment variables, API keys, and connection strings.
✅ If the hosting provider manages emails, transfer email accounts, DNS records, and backups.
✅ Ensure all background tasks, reports, and scheduled scripts are set up correctly.

Domain Configuration

✅ Modify A, CNAME, and MX records to point to the new hosting provider.
✅ Ensure traffic routing in load balancer and failover mechanisms work properly.
✅ If using a CDN, update settings to reflect the new server location.
✅ If specific IPs are whitelisted for API access, update them accordingly.
✅ Ensure outbound emails work correctly after migration.

Testing

✅ Test web applications, APIs, and backend systems for issues.
✅ Ensure that data consistency and relationships remain intact.
✅ Validate firewall rules, authentication mechanisms, and SSL configurations.
✅ Ensure logs are being collected and monitoring tools are configured correctly. ✅Prepare the holding page.
✅ Have key users validate the application before the final switchover.

Final Cutover

✅ Plan for an off-peak cutover to minimize business impact, ideally the weekend if you are migrating corporate projects.
✅ Keep a close eye on CPU, memory, database queries, and server load.
✅ Ensure new backup processes are working correctly.
✅ Once everything is verified, cancel the old hosting subscription to avoid extra costs.
✅ Note any challenges faced during migration to improve future processes.

Things to Consider Outside Technology

✅ Take regular breaks to keep your mind fresh. Do not try to do everything in one go.
✅ Migration is stressful, so boost your energy level with a beverage or other essential boosting process(as you can see my boosting process below).

Migrating hosting can be a high-risk, high-impact process, but a detailed checklist ensures nothing gets overlooked. By carefully planning, testing, and monitoring every step, you can minimize downtime, prevent data loss, and ensure a seamless transition.

As our business expanded, we needed a high-availability solution for our SQL databases to ensure reliability and disaster recovery. Initially, we relied on SQL Server Mirroring, which provided redundancy at the database level. However, as our infrastructure expanded, we faced multiple challenges that made mirroring increasingly difficult to manage. Eventually, at the end of 2018, we decided to transition to SQL Server Clustering, which offered better scalability and stability.

So what are the reasons that drove us to change from mirroring to clustering?

Growing Number of Databases and Management Overhead

In SQL Mirroring, each database requires an individual mirroring setup. While this worked well initially, as our business expanded and the number of databases increased, this approach created significant administrative overhead. For example:

Manual Configuration: Setting up mirroring for each new database required manual intervention, which was time-consuming and prone to human error.

Monitoring Complexity: Monitoring the health and synchronization status of multiple mirrored databases became increasingly challenging as the number of databases grew.

Resource Consumption: Each mirrored database consumed additional resources, such as network bandwidth and storage, which added up as the number of databases increased.

In contrast, SQL Clustering operates at the instance level, allowing us to manage multiple databases under a single umbrella. This significantly reduced the administrative burden and streamlined our operations.

Inability to Mirror System Databases

One of the most critical limitations of SQL Mirroring was its inability to mirror system databases (e.g., master, msdb, model, and tempdb). These databases play a vital role in our operations:

Email and Reporting: We rely on the msdb database for SQL Server Agent jobs, which handle tasks like sending emails and generating reports.

Centralized Configuration: The master database stores server-wide configuration settings, logins, and other critical metadata.

Without the ability to mirror system databases, we were forced to rely on a single server for these essential functions. This created a single point of failure, which was unacceptable for our business continuity and disaster recovery plans. SQL Clustering, on the other hand, provides high availability for the entire SQL Server instance, including system databases, ensuring seamless failover and minimal downtime.

---

Additional Challenges with SQL Mirroring

Beyond the two main reasons, we faced several other practical disadvantages with SQL Mirroring:

Limited Failover Capabilities: SQL Mirroring requires manual intervention for failover in some configurations (e.g., high-performance mode), which can lead to extended downtime during outages.

No Readable Secondary Database: Unlike SQL Clustering or Always On Availability Groups, SQL Mirroring does not allow the secondary database to be used for read-only operations, limiting our ability to offload reporting workloads.

Network Dependency: Mirroring relies heavily on a stable and high-bandwidth network connection. Any network issues could disrupt synchronization, leading to potential data loss or delays.

Deprecation Concerns: Microsoft announced the deprecation of SQL Mirroring in favor of newer technologies like Always On Availability Groups. This made it clear that continuing with mirroring would not be a sustainable long-term solution.

---

Why SQL Clustering Was the Right Choice

SQL Clustering addressed many of the limitations we faced with SQL Mirroring:

Instance-Level High Availability: Clustering provides failover capabilities at the instance level, ensuring that all databases, including system databases, are protected.

Simplified Management: With clustering, we no longer needed to configure and monitor individual database mirrors, reducing administrative overhead.

Improved Resource Utilization: Clustering allows for better resource allocation and scalability, which is essential as our database environment continues to grow.

Future-Proofing: By adopting SQL Clustering, we aligned ourselves with modern high-availability solutions, ensuring compatibility with future SQL Server updates and features.

---

Mirroring had become challenging to maintain due to our growing number of databases, lack of system database mirroring, and various performance and management drawbacks. The deprecation of mirroring and the need for a scalable and resilient solution led us to migrate to SQL Server Clustering. SQL Clustering has since proven to be a reliable and efficient choice, enabling us to maintain high availability, streamline management, and support our expanding operations. Yes, SQL clustering is more expensive than Mirroring, but the benefit it brings is worth the extra cost.

In the world of web hosting, there is no shortage of tutorials and guides for hosting architectures. However, when it comes to applications based on Microsoft technology that require hosting in IIS, finding a decent, easy-to-follow architecture is surprisingly challenging. The goal is to provide a simple yet effective Windows hosting architecture that serves the purpose of medium-large-sized applications that require scalability and high availability. Depending on the number of users and scale of the application, the configuration can be hardware can be changed, but the architecture should remain the same.

To provide a clear and practical architecture that addresses the core components needed for a functional and reliable setup, the article is divided into 4 areas.

Network Configuration: To discuss how to set up a secure and efficient network infrastructure, including firewalls, load balancers, and DNS settings, to ensure smooth communication between servers and clients.

Web Server Setup: This section will focus on configuring a Windows-based web server (e.g., IIS – Internet Information Services) to host your applications, handle HTTP/HTTPS requests, and optimize performance.

Database Server: A robust hosting architecture requires a reliable database server. We’ll explore how to set up and manage a database server (e.g., Microsoft SQL Server) to store and retrieve data efficiently while ensuring security and scalability.

Backup and Data Recovery: No hosting architecture is complete without a solid backup strategy. We’ll walk through setting up automated backups, storing data securely, and implementing a recovery plan to minimize downtime in case of failures.

By the end of this article, you should have a clear understanding of how to build a simple yet effective Windows hosting architecture that meets your needs.

Network Configuration

A robust network infrastructure is the backbone of any hosting architecture. For a Windows-based hosting environment, ensuring high availability, security, and performance is critical. This is where a redundant pair of active/passive Cisco firewalls and a redundant pair of Layer 7 load balancers come into play. Redundancy is a key principle in designing a reliable hosting architecture. By implementing redundant pairs of firewalls and load balancers, you ensure that your network remains operational even in the event of hardware failures or unexpected issues. Let’s break down why these components are essential and how they contribute to a reliable hosting setup.

Redundant Pair of Active/Passive Cisco Firewalls

Firewalls are the first line of defense in any network, protecting your hosting environment from unauthorized access, malicious attacks, and data breaches. Yes, you can use a WAF or web application firewall for your application. Still, Hardware firewalls are physical devices that serve as a gatekeeper between the network and the external environment, managing traffic and providing security. For large-scale projects, it is better to use a proper firewall to ensure security.

Using a redundant pair of Cisco firewalls in an active/passive configuration ensures:

High Availability: If the active firewall fails, the passive firewall immediately takes over, ensuring uninterrupted protection and minimizing downtime.

Enhanced Security: Cisco firewalls are known for their advanced security features, including intrusion prevention systems (IPS), deep packet inspection, and VPN support, which safeguard your network from external threats.

Scalability: As your hosting needs grow, Cisco firewalls can handle increased traffic and adapt to more complex security requirements.

In an active/passive setup, one firewall actively manages traffic while the other remains on standby, ready to take over in case of a failure. This redundancy is crucial for maintaining uptime and ensuring business continuity.

Redundant Pair of Layer 7 Load Balancers

Load balancers are essential for distributing incoming traffic across multiple web servers, ensuring optimal performance and preventing server overload. Using a redundant pair of Layer 7 load balancers provides the following benefits:

Traffic Distribution: Layer 7 load balancers operate at the application layer, meaning they can make intelligent routing decisions based on content, such as URLs or cookies. This ensures that traffic is evenly distributed across your web servers, improving response times and user experience.

High Availability: Similar to the firewalls, a redundant pair of load balancers ensures that if one fails, the other can seamlessly take over, preventing service disruptions.

Health Monitoring: Layer 7 load balancers can monitor the health of your web servers and automatically route traffic away from any server that is down or underperforming.

SSL Offloading: By handling SSL/TLS termination at the load balancer level, you can reduce the computational load on your web servers, improving overall performance.

Web Server Setup

Once the network infrastructure is in place, the next critical component of your hosting architecture is the web server layer. For a scalable and high-performance Windows hosting environment, it’s recommended to use multiple web servers behind a load balancer. This setup ensures that your application can handle increasing traffic loads while maintaining high availability.

Load-Balanced Multiple Web Servers

Depending on your application load and requirement you can add from 2 to n number of the web server in this layer. You need to ensure that each web server is configured identically to maintain consistency in application behavior.

Here’s why this approach is beneficial:

Scalability: Adding more web servers allows you to scale horizontally, distributing the load across multiple machines. This ensures that your application can handle traffic spikes without performance degradation.

Fault Tolerance: If one web server fails, the load balancer will automatically route traffic to the remaining servers, ensuring uninterrupted service.

Performance Optimization: By distributing traffic evenly, you can reduce the load on individual servers, improving response times and overall user experience.

To implement this, configure your Layer 7 load balancer (discussed in the Network Configuration section) to distribute incoming HTTP/HTTPS requests across all available web servers.

IIS Synchronization for Code Deployment

One of the challenges of managing multiple web servers is ensuring that all servers have the same codebase and configuration. This is where IIS (Internet Information Services) synchronization comes into play. By synchronizing your web servers, you can ensure that any code or configuration changes made on one server are automatically replicated to the others. Here’s how to achieve this:

Shared Configuration: Use IIS’s shared configuration feature to store configuration files (e.g., applicationHost.config) in a central location, such as a network share or a cloud storage service. This ensures that all web servers use the same settings.

Web Deploy Tool: Microsoft’s Web Deploy Tool is a powerful utility that allows you to synchronize websites, applications, and content across multiple servers. When you release new code on one server, Web Deploy can automatically replicate the changes to all other servers in the farm.

Automated Scripts: For advanced setups, you can create scripts (e.g., using PowerShell) to automate the synchronization process. This ensures that code deployments are consistent and error-free.

Database Server

The database is the heart of any application, storing and managing critical data. For a robust Windows hosting architecture, it’s essential to ensure that your database layer is both performant and highly available. There are a few options that you can choose from like Failover cluster, database mirroring, log shipping etc. But two Microsoft SQL Server instances in a failover cluster configuration, provide better redundancy and minimize downtime in case of failures.

Why Use a Failover Cluster?

A failover cluster is a group of servers that work together to provide high availability for applications and services. In the context of Microsoft SQL Server, a failover cluster ensures that if one database server fails, the other server automatically takes over, ensuring uninterrupted access to your data. Here’s why this setup is crucial:

High Availability: By using two SQL Server instances in a failover cluster, you eliminate single points of failure. If the primary server goes down, the secondary server takes over seamlessly, minimizing downtime.

Data Integrity: Failover clusters ensure that your data remains consistent and accessible, even during hardware or software failures.

Scalability: This setup allows you to scale your database layer as your application grows, without compromising on reliability.

Alternative to Failover Cluster: SQL Server Always On Availability Groups

While a failover cluster is a robust solution for high availability, it may not be the best fit for every scenario. For example, setting up a failover cluster requires shared storage and can be complex to configure and maintain. If you’re looking for a more flexible or simpler alternative, SQL Server Always On Availability Groups is an excellent option.

Always On Availability Groups (AGs) are a high-availability and disaster recovery solution introduced in Microsoft SQL Server 2012. They provide database-level redundancy by allowing you to group multiple databases into a single availability group and replicate them across multiple SQL Server instances. Here’s why AGs are a great alternative:

Database-Level Redundancy: Unlike failover clusters, which operate at the instance level, AGs work at the database level. This means you can replicate specific databases rather than the entire SQL Server instance, providing more granular control.

No Shared Storage Required: AGs do not require shared storage, simplifying the infrastructure and reducing costs.

Readable Secondaries: Secondary replicas in an AG can be configured as read-only, allowing you to offload read operations (e.g., reporting or analytics) to the secondary server, improving performance.

Automatic or Manual Failover: AGs support both automatic and manual failover, giving you flexibility in how you manage high availability.

When to Choose Always On Availability Groups Over Failover Clustering

Granular Control: If you only need high availability for specific databases, AGs are a better choice.

Cost Efficiency: AGs eliminate the need for shared storage, reducing infrastructure costs.

Read-Only Workloads: If you want to offload read operations to secondary replicas, AGs provide this capability out of the box.

Other Alternatives

Database Mirroring: An older high-availability feature that provides database-level redundancy. However, it’s deprecated in favor of Always On Availability Groups.

Log Shipping: A simpler solution for disaster recovery, where transaction logs are periodically shipped and applied to a secondary server. While it’s not as robust as AGs or failover clustering, it’s easier to set up and maintain.

Dedicated Storage Layer for Backup

No hosting architecture is complete without a reliable backup and recovery plan. Data loss can occur due to hardware failures, software bugs, human errors, or even cyberattacks. To safeguard your data, it’s essential to implement a dedicated storage layer for backups, coupled with a comprehensive backup strategy.

Why a Dedicated Backup Storage Layer?

A dedicated storage layer for backups ensures that your data is securely stored, easily recoverable, and protected from accidental deletion or corruption. Here’s why it’s critical:

Disaster Recovery: In the event of a catastrophic failure, backups allow you to restore your application and data quickly, minimizing downtime.

Compliance: Many industries require businesses to maintain backups for regulatory compliance.

Data Integrity: Regular backups ensure that you can recover from data corruption or accidental deletions.

It is important to Maintain at least three copies of your data (primary + two backups), store them on two different types of media, and keep one copy offsite or in the cloud. Periodically test of your backups are very important to ensure they can be restored successfully.

Using Commvault for Backup

Commvault is a powerful enterprise-grade backup and recovery solution that provides a unified platform for managing backups across on-premises, cloud, and hybrid environments. Here’s how to leverage Commvault for your backup strategy:
