• Continuous Integration and Continuous Delivery Pipeline in AWS (CICD) – GitHub, CodeBuild, Test, CodeDeploy, AWS CodeStar
• Docker – used to build project and deploy
• Cloud Formation
• EC2 – Auto scale “64bit Windows Server 2016 v1.2.0 running IIS 10.0” EC2 instances are used.
• ELB – used for load balancing
• AutoScaling Group – Multi AZ deployment is set for auto scaling
• AWS SAM(Serverless Application Model). Lambda:
  1. Worker Lambda to initiate task in Step Function workflow.
  2. Post Workflow update lambda. Triggered as a part of Step Function.
• AWS Step Functions State machine Workflow implementation for task orchestration
• API Gateway – Endpoint for email approval. Integrates to Step function.
• Amazon Simple Email Service (SES) Useing to send emails for approvals
• Single AZ RDS Db converted to Multi AZ Select Instance -> Instance Action -> Modify -> Multi AZ deployment to Yes.

• Visual Studio 2017
• Clone project and open in Visual studio 2017
• Enter your RDS MySQL database connection string in parameter store.
• Use IAM roles for S3 access
• Set up AWS infrastructure
• Setup Azure AD (Will cover in another article for How to)
• Now run your application
• This project is deployed on AWS Elastic Beanstalk on Multi AZ servers with load balancer and autoscaling.

In AWS following are the main technologies which are required to run App. However I used more to make secure, highly available, reliable and scalable application.

1. Create following two Lambada functions as code in code base.
   1. Lambda to invoke workflow and send email for approval.
   2. Post approval activity lambda
2. Ctreate StateMachine with two tasks as codein Architecture diagrams. Set IAM role and configurations.
3. Create API Gateway and take promoid as request get parameter.
4. Create S3 bucket with name as “homework2-manoj”. Enable versioning and transfer acceleration. Lifecycle can be set as architecture diagram to save cost. I also set permissions, user and group in IAM.
5. Configure CICD.
6. Create RSD MySQL database as per your connection string. Run DBscript folder script to create tables and sample data.
7. Configure other component as in technology stack.
