With digital presence in more than 190 countries, the organization has been able to carve a niche for themselves in the industry.

Challenges Faced

The Customer was looking to run their .NET based application on AWS Cloud. They had multiple websites running. All sites had been developed on a 2-tier architecture with User Interface on a Database layer. All sites under the domains were running on multiple Web servers with SQL Server Standard edition as DB. Customer wanted to migrate their current infrastructure to AWS and looking for the App Maisters team to provide Managed Services.

Project Solution

Web servers were provisioned under ALB. All the websites were deployed on both the web servers
All the servers except the RDP server were hosted in private subnet
Only load balancer and RDP servers were in public subnet
The web servers had a file server mounted for use during deployments as well as user uploads
SQL Server Standard License was included as part of the AWS Infra Cost
Active Directory and DNS were run in High Availability mode across 2 AZ’s, one in an EC2 and one in file server
AWS S3 was used for any Data / Logs backups.
NAT Gateway was added which is Highly Available AWS Managed Service.
Periodic Automatic Snapshots were built in, on successful completion of POC.
EBS – Extension of Hard disk size was automated to manage cost and data growth requirements.
AWS CloudWatch was used for monitoring.
AWS CloudTrail was setup for API and account activity tracking.

Results

App Maisters team went online with a reliable infrastructure which met all of their demands. Because of the elastic nature of the architecture, the solution was able to scale to meet demand of the application when the traffic was high on the websites.
