AWS, ECS, API Gateway

Quick slides for a presentation on AWS, ECS and API Gateway.

Transcript

1. AWS, ECS, API Gateway A quick discussion
2. History In early 2018 we started building a set of Microservice APIs: - Kotlin / Spring Boot - Containers - ECS on EC2 - ALB - Route 53
3. API Gateway We experimented with API Gateway, found pros and cons
4. API Gateway: Pros • Built-in suppport for: • API Keys • Usage Plans • Future expansion for: • Authoriza=on • Facade over mul=ple APIs
5. API Gateway: Cons • API Structure Replicated • Each endpoint needed to be configured • Addi9onal complexity (one more technology)
6. Fast Forward to Now • Built simple custom API keys • No usage limit for now • Built second API • Not currently using a facade to unify
7. Architecture: Base • ALB Default Rules • HTTP redirect to HTTPS • HTTPS default response: "Can't find environment"
8. Architecture: Deployment Each deployment adds: Target Group, ALB Host Rule, ECS Service/ Task Def
9. Architecture: Deployments
10. Automa'on Automa'on in Python 3 w/ Boto: ❯ scripts/deploy -h Submit API Deploy usage: deploy [-h] {list,create,watch,update,stop,check,remove} ... Submit API Environments positional arguments: {list,create,watch,update,stop,check,remove} list Lists the current Submit API deployments create Creates a new deployment of Submit API watch Watches any events from any ongoing deployment activity. update Updates a deployment. stop Stops the service from running by setting the desired count to zero (and then watching the events until the goal is reached). check Check all the pieces that make up a deployment to make sure the deployment is in a good state. remove Removes the deployment and all associated pieces (ECS service, task definition, target group, etc) optional arguments: -h, --help show this help message and exit
11. Automa'on: Copilot A bit like a customized version of AWS Copilot CLI:
12. API Gateway Changes • HTTP APIs • Wildcard Domain Names for HTTP APIs • OAS 3.0
13. Future Needs • More auth • Might be Azure Ac1ve Directory • Might be Okta • ?
14. Discussion • Thought on current approach? • Pros/Cons on API Gateway? • Mul;ple Deployments, Automa;on? • REST vs HTTP APIs?
