The Customers infra was hosted in US East (N.Virginia) Region. With the launch of a Region in Mumbai, Customer was keen on migrating the entire set-up to the newly launched Region. The main concern was about having the data and information within India only. This would also provide lower latency to India-based end users.
The customer leveraged various AWS services like Load Balancing, Amazon RDS databases, Amazon S3 with EC2 instances with internal dependencies resulting in a complex architecture. Existing infra was already in a AWS Account. The environment was Windows based. The instances were to be migrated to a new AWS Account in Mumbai region. There were no external third party dependencies. Amazon Route 53 was used for routing internet traffic to the resources. Which also had to be migrated. Amazon CloudFront Setup required for accelerating delivery of static content. The Migration process was completed in a week’s time frame.
The Migration process was accomplished with zero downtime. The internal inserts by the team were frozen for a window of 15 mins. Post Migration the customer has witnessed enormous benefits. The customer’s data now resides in India. The customer can now access data with low latency and high data transfer rate. As other AWS regions, Mumbai region is also designed and built to meet most of the compliance standards.
