Streamlined Deployment Process for 50+ Microservices on Ubuntu 22 EC2 Instances for a FinTech

Solutions

• All resource creation and deployment occur automatically using AWS CloudFormation templates, eliminating the need for manual intervention. 

• Cloudformation template versions in place to track and manage changes in the infrastructure and mapping were used for enabling dynamic and region-specific resource allocation. 

• Utilize Amazon EC2 instances with Ubuntu 22 for hosting microservices, ensuring compatibility and security. 

• Implement Ansible playbooks for CIS hardening of Ubuntu 22 across environments to enhance security and compliance. 

• Implementing Amazon API Gateway to work with AWS Lambda function as an internal authorizer, while the API Gateway acts as a proxy for internal domain routing between microservices. 

• Set up the Amazon EC2 Image Builder pipeline and AWS Lambda function to automate the creation and deployment of the latest versions of Ubuntu 22 AMIs, ensuring consistency and security. 

• Develop AWS Lambda functions and SSM documents to automate system security and compliance remediation, orchestrated via AWS CloudFormation templates to ensure consistency and scalability. 

• Utilizing Spot Instances for microservices running on lower environment Amazon EC2 instances to streamline resource provisioning and cost optimization.
