Heroku to AWS Migration

A growing SaaS outgrew Heroku and their technology stack and decided to migrate to AWS and simultaneously re-platform. As part of a small, three-person operations team, I was tasked with:

Standing up the platform at AWS

• implementing AWS CloudFormation templates to create and configure the infrastructure for the platform
• creating Chef cookbooks for deploying non-Dockerized services like Jenkins and others
• creating Dockerfiles for deploying the various microservices that made up the platform
• building CI/CD pipelines for each microservice
• building out standardized logging and monitoring solutions
• helping develop a disaster recovery (DR) plan

Re-platforming

• helping migrate to highly available technologies and services (ex: Cassandra, Kafka, Zookeeper)
• creating Chef cookbooks, Dockerfiles, and Packer templates to stand-up experimental or new services
• helping configure and optimize new services based on best practices
• hardening all services with the goal to support new clients with compliance needs (ex: HIPAA)
