A start-up client wanted to deploy an ERP and a Web Application to AWS Cloud. Hosting an application on AWS comes with lot of perks and benefits. Some are as under:

• High level of Scalability
• Better and easy Secure posturing
• Operational Efficiency
• Cost effectiveness
• Comparatively better Performance

AWS Services:

• AWS EC2
• AWS S3
• Site-to-Site VPN Gateway
• AWS CloudWatch
• AWS CloudTrail

Other Services:

• Microsoft SQL Server
• Window Server 2016

Assessment, Analysis and Design:

1. Application was not hosted anywhere. We analysed and assessed the system requirements, application capabilities, dependencies and the applications ability to leverage AWS services.
2. We designed the architecture based on our assessment
3. We validated the functionality of the architecture by discussing with the application team and deploying the application on a UAT environment.

Implementation:

1. We deployed the production environment seamlessly.
2. We started by deploying the VPC and configuring the Subnets, Security Groups and Route Table appropriately
3. We then deployed the instances; 1 Microsoft SQL Server for the ERP Database, 1 Windows Server 2016 for Active Directory, 2 Microsoft Servers 2016 for the ERP and Web Application respectively.
4. After that, the application vendor deployed the application on the launched instances, tested it.
5. We also configured S3 for database backup and snapshots.
6. Next, we configure CloudWatch and CloudTrail appropriately.
7. Finally, we launched AWS Site-to-Site VPN Service to securely access the infrastructure from the client on-premises infrastructure.
