Our AWS Architect designed the approach to migrate to AWS over a minimum timescale. The key features of the approach were:
- Re-architect and segregate servers to multiple EC2 instances
- Load balance the server environment
- Security including SSO using Microsoft AD
- Multi-platform accessibility – PC – any OS, Tablet, Smartphone
- No downtime during the migration
- Ensure no data loss
- Increased Stability
- Lower infrastructure management effort
We rearchitected & segregated their on-prem window server to multiple EC2 instances with separate Application and Database tier. On EC2 instances, we had set up and installed the Sage HRMS server, SAGE 100 server, Sage crystal 2011 on the Application Server, SQL Server (Web Edition) on the Database server. ELB Load balancers were set-up to ensure High Availability.
A Security first approach was followed by using custom rules in security groups and subnets in the combination with NAT gateway to have a high level of security.
