Scaling Heights: Mastering WordPress on AWS for Ultimate Performance
I’ll be writing a blog series providing a journey of a WordPress Application’s transformation. The application has the architecture as shown in Fig. 1, and the transformation will enhance its scalability, availability, and performance using various AWS services and components.
Running a WordPress application on a single EC2 instance comes with inherent limitations that can impact the performance, availability, and overall scalability of the website. The primary constraint lies in the ability to scale vertically only, meaning that you can only increase the resources (such as CPU and RAM) of the single instance to a certain extent. This approach is not always cost-effective and may lead to performance bottlenecks during traffic spikes.
Moreover, having a single EC2 instance poses a significant risk as it represents a single point of failure. Any issues or failures with this instance can result in downtime, affecting the user experience and potentially causing data loss.
Maintenance tasks and updates on a single instance often require downtime, as there is no redundancy to handle traffic during these processes. The lack of fault tolerance and redundancy in a single EC2 instance setup can also lead to challenges in ensuring a consistently available website.
Security concerns arise from having a single attack surface, making the website more susceptible to security threats. As the application and user base grows, manual management becomes more complex, and resource utilization may not be optimal, leading to inefficiencies and increased costs.
This blog series aims to address these limitations by exploring the migration of a WordPress application from a single EC2 instance to a more robust and scalable architecture using AWS services. Each episode in the series will focus on specific components to enhance scalability, availability, and performance, ultimately providing a comprehensive guide for optimizing WordPress on AWS.
This series will include several episodes as part of the transformation journey.
Episode Guide:
Episode 1: “Database Ascendance”
