INFRASTRUCTURE MIGRATION

Subsidiary of a global software giant, that develops innovative software products and offers them on premise or as cloud-hosted business platforms, needed to migrate its infrastructure from a public cloud to AWS.

THE APPROACH

  • Scalable, architecture-based deployment
    • Multiple availability zones created to enable high availability
    • Central services VPC to host shared services
    • Multiple dedicated application-specific VPCs
  • Application stack was rebuilt by application team

TECHNOLOGY COMPONENTS

  • CloudTrail for audit trail purposes
  • IAM for Role-Based Access Control
  • VPC for hosting the solution
  • Security Groups for firewalling
  • EC2 for compute
  • ELB for load balancing
  • IaaS upgraded to PaaS
    • MySQL on Cloud VM to AWS RDS MySQL
    • NATing offloaded to AWS NAT Gateway
    • Object storage offloaded to S3
    • CloudWatch for monitoring and alerting

THE BUSINESS CHALLENGE

The client was unable to scale the infrastructure and found it difficult to host the multitenant solution on existing cloud platform. Lack of a central security management system and a limited understanding of current deployment architecture from available documentation also increased the challenge.

TRANSFORMATIONAL EFFECTS

  • All omnichannel commerce solutions successfully moved from existing public cloud to AWS
  • Scalable architecture at individual service as well as at solution level
  • Central Security Management solution enhanced the infrastructure security
  • PaaS services employed for higher level of management of services
  • Fault tolerance and highly available solution (limited by application capability)
  • Client educated on AWS as well as day-to-day operations best practices
  • Complete AWS deployment documentation support
