Summary
Our client was operating six web applications hosted on multiple on-premise servers. These applications were running on a single in-house data center, responsible for both web server functionalities and storage. The data center infrastructure also included three MySQL database servers. Their team was planning to migrate their entire on-premise server infrastructure, including web servers and MySQL databases, to the AWS cloud and looking for an expert solution to ensure a secure and efficient migration process.
Challenges
• Lack of documentation support and redundant data for on premise datacenter.
• Poor application performance while accessing from different geo-locations
• Difficulty in scaling infrastructure to handle increased load and user traffic.
• Significant expenses for maintaining hardware, cooling, and power.
• Lack of redundancy leading to potential single points of failure.
• Increased vulnerability to physical and cyber threats.
• Insufficient disaster recovery and backup solutions.
• Frequent downtime and reliability issues affecting application availability.
• Difficulty in meeting compliance standards and regulatory requirements
Solution
Our client planned to migrate its on-premise web application servers and MySQL database servers to the AWS cloud. The goal was to achieve enhanced security, scalability, reliability, and cost-efficiency with minimal downtime during the migration process. The solution included:
Phase: 1 Pre-Migration Phase
Assessment and Planning
• Evaluated existing on-premise infrastructure, including server configurations, application dependencies, and database schemas.
• AWS Service Mapping: Identified AWS services that match current infrastructure needs (e.g., EC2, RDS, S3, VPC, Route53).
• Migration Plan: Developed a comprehensive plan detailing the migration strategy, timeline, and risk mitigation measures.
Phase: 2 Migration Phase
1. AWS Environment Setup
• Set up Virtual Private Cloud (VPC) with subnets, route tables, and gateways.
• S3 Buckets: Created S3 buckets for temporary data storage during migration.
2. Database Migration
• Used DMS to migrate MySQL databases to Amazon RDS for MySQL.
• Used AWS Application Migration Service (MGN) to replicate on-premise servers to EC2 instances.
• Used Replication agent Perform full load and continuous data replication to ensure data integrity.
• Tested the migrated databases for functionality and performance.
3. DNS Configuration
• Used Amazon Route 53 to manage DNS records and route traffic to AWS-hosted applications.
Phase: 3 Post-Migration Phase
1. Testing and Validation
• Tested web applications and databases to ensure they are working correctly in the AWS environment.
2. Monitoring
• Set up AWS CloudWatch for monitoring and AWS CloudTrail for auditing. Implement alerts for critical events and performance metrics.
3. Training and Handover
• Provided training sessions for client's IT staff on AWS management and best practices.
• Delivered detailed documentation of the new infrastructure, including configurations, access policies, and troubleshooting guides.
• Offered post-migration support to address any issues and ensure smooth operation.
