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
