Business Challenges

  • The client had over 50 business-critical applications to be migrated to AWS Cloud
  • Few hurdles the client was facing were- Increase in IT operational cost, Legacy infrastructure environment, Manual build and release processes, Non-alignment of SLAs with business needs, Lack of technical architects, increased traffic load etc.

Solution Offered

  • AdfarTech migrated all the services from two data centers (from 2 locations) in 9 sprints to AWS.

  • Robust, Flexible, and Achievable Plan: Delivery of services as per business criticality was planned in such a way that learning from each sprint was fed to the subsequent sprint.
  • Migration and Delivery Approach: Lift & shift approach using AWS migration services using agile practices by identifying key applications and their dependencies.
  • CI-CD: Infrastructure as a Code: Services for new project were launched using Cloud-formation scripts, Jenkins and Ansible
  • Monitor and Secure: Cloud tools (CloudWatch, CloudTrail, WAF) were planned and implemented

Value Delivered
