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 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.
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 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
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
