- 12. Copyright © 2017,Oracle and/or its affiliates. All rights reserved. | Our Challenges • Ephemeral Containers – WebLogic traditionally static IP addresses • Restart or scale admin or managed server • No more WebLogic Proxy plugin • Multiple networks presented at container startup with mesh – Each WebLogic instance could start with different IP/subnet (random) • Logging – Many different logs (Access, nohup, app specific, etc.) Confidential – Oracle Internal/Restricted/Highly Restricted 12

- 15. Copyright © 2017,Oracle and/or its affiliates. All rights reserved. | Common Challenges • Applications • Developer code often works on one environment, fails on other environments because the environments are not identical • Production Support • Both developer and platform administrator often feel helpless when production has performance or stability issues because developer does not know platform environment and platform administrator does not have application knowledge • Product Patch and Upgrade • Platform administrator often repeats patch or upgrade for tens or hundreds times because the environments are different • Environment Provision • Due to complex approval or change request (CR) process, it takes long time for system administrator and platform administrator to provision a new environment Confidential – Oracle Internal/Restricted/Highly Restricted 15

- 21. Copyright © 2017,Oracle and/or its affiliates. All rights reserved. | Migration Path to DevOps Model • The most critical step: migrate existing applications – Guiding principle: Lift and Shift as much as possible – Solutions for WebLogic applications • Each application has its own domain • Each WebLogic server has its own dedicated container • Each domain has at least two servers – A singleton admin server with shared storage for failover – 1+ immutable and disposable managed servers – Admin server manages J2EE resources for managed servers – Container orchestration manage WebLogic server life cycle as well as scalability and failover Confidential – Oracle Internal/Restricted/Highly Restricted 21
