• Works on multiple projects
• Often multiple languages/frameworks
• Focused on the requirements
• Testing can often be an afterthought
– Especially when time pressured
– It works… (on my machine)
– Infrastructure – do I really need to care?

• What does my service need to do for the business?
• I want to develop in a language I like!
• How do I fix/build/change somebody else’s code?
• How do I know it works?
• What code quality / style do I need to ‘comply’ with?
• I don’t care what it has to run on – that’s for operations to worry about!
• The others in the team better not break what I’m doing!
• Operations can sort the deployment so I can write more code!

• I want my microservice to be micro
– I don’t want to create aggregated services or concern myself with latency– it’s fast on
my machine!
• I don’t want to have to worry about security
– I don’t want to bloat out the implementation with sometimes complex security
requirements (authorization/ssl)
• I don’t want to have to spend my working life fixing issues caused by tight
dependencies between client applications consuming my microservices
• I still want my microservice to be able to scale as intended
• I don’t want to worry about load/caching requirements for my microservice
I just want to write interesting code

API GATEWAY
TYPICAL ARCHITECTURE
• Main / Edge gateway serves north-south traffic
• Protects and mediates public APIs
• Microgateways serve east-west traffic
• Protect and mediate private APIs
• They are light weight and only carry the policies they need right now

• Docker is a tool designed to make it
easier to create, deploy, and run
applications by using containers which
allow a developer to package up an
application with all of the parts it
needs, such as libraries and other
dependencies, and ship it all out as
one package.
Docker Kubernetes
• Modern applications are increasingly
built using containers—microservices
packaged with their dependencies and
configurations. Kubernetes, or k8s for
short, is open-source software for
deploying and managing those
containers at scale. With Kubernetes,
you can build, deliver, and scale
containerized apps faster.

• I don’t want to know/care about what infrastructure my microservice runs on
• My service is stateless - I shouldn’t have to worry about scale
• Deployment – that’s boring
• I just want to write some code

KEY TAKEAWAYS
3 KEY TAKEAWAYS
DevOps creates hands off automated quality gates through the CI process, and
hands off, but manually approved automated test/production deployments to
allow you to release at a much quicker pace whilst minimizing risk 1
Micro API Gateways in combination with a full API Gateway are a powerful
mechanism to ensure your microservices remain focused on the task at hand
and offload ancilliary and sometimes complex tasks to avoid complicating the
micro service
2
Kubernetes offers really powerful infrastructure as code and deployment
techniques to allow you to truly update with ZERO downtime, and minimal fuss
in doing so 3
You!
