Microservices have been growing in popularity over the last few years, but questions still abound: What are they? Why would my organization need them? How can they help my business? This webinar offers an opinionated but dogma-free approach to bringing microservices into your organization -- regardless of language or technology stack -- to help you get products delivered faster, more securely, and with fewer errors. Attendees will hear how AppDynamics has helped both Fortune 50-500 companies in the U.S. and organizations around the world: Leverage microservices to optimize the software development lifecycle Avoid common pitfalls and problems with implementation Drive internal adoption of microservices best practices to drive efficiency

Why we organize Microservices by domain?
It does a few things for us.
• Enables us to speak in a common language with the
business alleviating miscommunication
• Allows us to create end to end ownership for a team
• The business and engineers work closer allowing for rapid
ideation, validation, and iteration

How do we think differently about UI in this paradigm?
• The UI is just another consumer of services
• The UI should go on a separate cadence as the
services as it will be the slowest to move through the
business process and the least impactful to system
stability
• Favor simple HTML and Javascript modules

What should we keep in mind for testing?
• Automate service testing and make it part of the CI/CD
process
• Keep the testing surface area limited to the domain that is
being published.
• Isolate a domain specific automated integration testing
environment for regression that can be drop and
recreated during the delivery process.

Containers
• Containers are GREAT for infrastructure/java/linux deploys
• .Net apps benefit less from containers
• Storage mechanisms should be durable and movable in
case of failure. Good choices include vSphere disk
virtualization or Azure File Storage mounted as a drive at
application startup.

• Having a “single pane of glass” greatly increases likelihood
of success
• Remember: Favor Existing Solutions

What is failure as a service?
• Use tools like Keyhole Trouble Maker or Built in Service
Fabric tools to randomly stop applications in production
• If your apps are able to handle this continual shutting off
of parts of the system you can sleep easy at night knowing
that the system is stable.
