Test Driven Development Courses

1. Run locally - bundle exec jekyll serve
2. Create build - JEKYLL_ENV=production bundle exec jekyll build

Microservices

• Complexity shifts from the inside (code, vertical stack) to the outside (platform, horizontal stack), managing each dependency, which can be good if you have a younger team in terms of developers. Junior developers are free to experiment and muck up smaller apps. You must have solid dev ops support though.
• Less coupling, which makes scaling easier
• Flexible - different apps can have different code bases and dependencies
• Can be slower since multiple requests and responses are often required
• Smaller code base, less coupled, solid API design, not having to understand the full system = easier to read code

Stateful vs stateless services

• Stateful - databases, message queues, service discovery
• Stateless - apps

Stateful containers should not come down. You should limit the number of these since they are hard to scale.

What code is common amongst all the services?

Generator for-

1. Auth
2. service discovery
3. RESTful routes
4. Unit and Integration test boilerplate
5. Config (via environment variables)
