Oracle Cloud on Premise

Roadmap

  • WLS 10.3.6 (11gR1): Java 6, JavaEE5
  • WLS 12.1.3+ (12cR1): Java 7, JavaEE6
  • WLS 12.2.1+ (12cR2): Java 7/8, JavaEE7
  • WLS 18? (2018): Java 9, JavaEE8

Oracle DB 2018
WLS 2018? not confirmed...

WLS v18 license

license model: universal credit, can be used in both platforms

  • on premise
  • cloud: on OCM (Oracle Cloud Machine)

Technically, docker.WLS can on other cloud, like Azure

Features of WLS 12.2.1+

  • Multitenant: can move from DEV to SIT
  • Continuously Availability: Multi-data centre resilience, Active-Active
  • DevOps

Docker Recommendation:

  • need refactoring the services to microservices
  • not docker everything, if the VM over 4G size, better not make it as docker

Oracle Developer Cloud

what is it?

  • Provide services: Git, Hudson, JUnit, ...
  • Developer can get IaaS provisioning easily, e.g. add a WLS managed server, Coherence, ...

How to use in HA?

  • Developer install Eclipse on client side, keep check in/out source code from SVN
  • update the WSLT, deploy to Oracle Cloud Platform

Dominic propose to use the Developer Cloud as 'Chaos Monkey'

  • since all environments cannot be touched, create a new testing environment for some extreme cases, e.g. shutdown DB
  • can use to log monitoring for those logs write to file, can make use of the Splunk

Follow up

Oracle: will follow up the price: 4 servers x 8 cores Dominic: will talk to CIO
