Migrating Web Applications to AWS: A Case Study in the EdTech Sector

Abstract

This case study presents the process of migrating a web application for icanonlinetutors.com - an EdTech company to Amazon Web Services (AWS). The organization, an online educational platform, sought to enhance scalability, improve performance, and ensure high availability for its growing user base. By leveraging AWS services, the company successfully migrated its web application, resulting in improved reliability, cost-efficiency, and streamlined management

Introduction

The EdTech sector has experienced significant growth in recent years, driven by the increasing demand for online learning platforms. To keep pace with the rising user base and ensure a seamless user experience, many organizations opt to migrate their web applications to cloud platforms like AWS. This case study explores the migration journey of an EdTech company and highlights the benefits achieved through the adoption of AWS services

Background

The EdTech organization operated a web application that facilitated e-learning experiences for students and educators. As the user base expanded, the existing infrastructure faced challenges related to scalability, reliability, and performance. To address these concerns, the organization decided to migrate its web application to AWS, leveraging EC2 for computing power and RDS for managing the relational database leveraging the experience of CloudPlexo, an AWS consulting partner, to achieve a successful migration

Migration Strategy

The migration process involved the following key steps

1. Analysis and Planning: Conducted a thorough analysis of the existing infrastructure, identifying dependencies, performance bottlenecks, and resource requirements. A detailed migration plan was formulated, outlining the timeline, resource allocation, and testing strategies
2. infrastructure setup: The company provisioned EC2 instances based on the anticipated workload and configured the necessary security groups, networking, and storage resources. The web application code was deployed onto the EC2 instances, ensuring compatibility with the AWS environment.
3. Database Migration: The organization utilized RDS to migrate the existing database to AWS. This involved exporting the database from the on-premises environment and importing it into the RDS instance. The compatibility and data integrity were thoroughly validated during the migration process.
4. Testing and Validation: Rigorous testing was performed to ensure the web application and database worked seamlessly within the AWS infrastructure. Load testing, failover testing, and data integrity checks were conducted to identify and rectify any performance or compatibility issues.
5. Go-Live and Post-Migration Optimization: Once the testing phase was completed successfully, the organization redirected the traffic to the new AWS infrastructure. Continuous monitoring, optimization, and fine-tuning were performed to maximize the performance, reliability, and cost-effectiveness of the web application.

Benefits and Outcomes

The migration to AWS provided several notable benefits for the EdTech organization:

1. Scalability: The organization gained the ability to dynamically scale the computing power and database resources to accommodate the growing user base, ensuring a responsive and reliable user experience.
2. High Availability: AWS's infrastructure allowed the organization to deploy its web application across multiple availability zones, minimising the risk of downtime and providing enhanced fault tolerance.
3. Performance Improvement: Leveraging AWS's robust infrastructure and optimised services, the EdTech company experienced improved performance, faster response times, and reduced latency, resulting in a better user experience.
4. CostOptimization: With the elasticity of EC2 instances and the cost-efficient pricing models of AWS, the organization could optimize its resource utilization and scale up or down as needed, leading to potential cost savings.
5. Simplified Management: AWS's management console and automation capabilities simplified the management of the web application infrastructure, enabling the organization's IT team to focus more on core business activities rather than infrastructure maintenance.
