Going Cloud Native with Docker

WTF is Cloud Native?





Actual Survey by Citrix





“Cloud native computing uses an open source software stack to deploy applications as microservices, packaging each part into its own container, and dynamically orchestrating those containers to optimize resource utilization.”

- Cloud Native Computing Foundation





Monoliths suck.





Cloud Native is about Flexibility.





Scale.

Replace.

Optimise.





Containers are the building blocks of the cloud.

Virtual Machines vs. Containers

Containers include the application and all of its dependencies --but share the kernel with other containers, running as isolated processes in user space on the host operating system. Docker containers are not tied to any specific infrastructure: they run on any computer, on any infrastructure, and in any cloud.

Virtual machines include the application, the necessary binaries and libraries, and an entire guest operating system -- all of which can amount to tens of GBs.

Cloud Native relies on automation





Build.





Test.





API Testing





Deploy.





Cloud Native is platform agnostic

Containers != Docker





Cloud Native

● Relies on Automation

● ...is Flexibility

● ...is about Resiliency

● ...is Platform Agnostic
