Micro-services?

10. Copyright © 2017, Oracle and/or its affiliates. All rights reserved. |
Prerequisite: Microservices
• Single monolithic application -> small,
independently deployable
microservices
• Each microservice:
– Has its own team that designs, builds,
deploys and maintains it
– Exposes an API, which can be consumed
elsewhere
– Has its own datastore/database
• Microservices are loosely coupled,
with most communication over REST
and async messaging

What are containers ?

25. Copyright © 2017, Oracle and/or its affiliates. All rights reserved. |Copyright © 2017, Oracle and/or its affiliates. All rights reserved. |
What is a Container?
Containers vs. VMs
VMs
Containers
Virtual Machines
Each virtual machine (VM) includes the
app, the necessary binaries and libraries
and an entire guest operating system
Containers
Containers include the app & all of its dependencies, but share the
kernel with other containers. Not tied to any specific infrastructure –
containers run on any computer, infrastructure and cloud.
