Flexagon Founded in 2014, HQ in Green Bay, Wisconsin Software Company, focused on DevOps and Automation Extensive experience... Oracle DB, Middleware, Apps, Cloud Open Source Tools Platform enablement, development, operations Automation build, deploy, and release lifecycle FlexDeploy DevOps Platform
Challenges with Software Delivery Manual activities are very costly Creating & maintaining environment and scripts Outages in test and production environments Cost Delays for environment provisioning/setup Slow deployment and release, impacting test cycle times Time spent troubleshooting issues vs. productive work Speed Poor Visibility to what, when, who, how Lack of Controls lead to compliance issues & failed audits Increased Risk for quality delivery Quality Too costly, slow, error prone, and high risk
What is DevOps?(Wikipedia) A culture, movement or practice that emphasizes the collaboration and communication of both software developers and other IT professionals while automating the process of software delivery and infrastructure changes; it aims at establishing a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably
The DevOps Conflict Development goals Operations goals Stability, Availability Planning Security and Control Simplicity What, where, who? Innovation Speed & Agility Ease of change More features Self Service Improve collaboration and effectiveness across Dev, Ops, Release Management, others.

SOA Approach Maximo Work Management v 7 Adapters Used: JMS DB File Rest Powerplant Asset Mgmt v 10 Oracle EBS R12 SOA Suite CIS Oracle CC&B V2.5 GE Energy Management v 10 ESRI Geographic Information v 10 GE Outage Management v 4
SOA History SOA Suite 12.2 Implementation - Oracle HCM integration - Mobile Workforce integration - add l 50 interfaces SOA Suite 10.x Implemenation - add l interfaces BPEL 11.x Implementation - BPO Implementation - Integrated triad (EBS, Maximo, PowerPlant) BPEL 10.x Implementation - 7 interfaces Oracle CC&B Implementation - add l 50 interfaces Oracle Cloud Implementation - add l interfaces | 2006 | 2008 | 2010 | 2016 | 2017 | 2018

State Development in 2017 Use SVN for version control (have for a long time) Blend of traditional and agile development Manual Deployments directly from JDeveloper to all SOA instances Limited audit requirements, generally the Wild West Small staff, many projects, struggling to keep up with business demand
Change Needed!!! Simply NOT Sustainable. We saw DevOps as solution to many challenges Automation is critical, for scalability/time and traceability We saw the potential benefits: repeatability, consistency, visibility Code control, no code could get to server without being in version control Solid audit path, making it easy to demonstrate to auditors Path for recording code deployment approvals Ability to mature into CI/CD over time Started investigating changes, including Flexagon s FlexDeploy in early 2017
Significant Improvements Current State Implemented FlexDeploy in summer 2017 for all SOA Suite 12C deployment Recognized immediate gains Productivity Ease of use Easy code-sharing with consultants Increased visibility, audit capabilities Environment topology, project structure, etc easily visible, available, and understandable Success story in Mobile Workforce implementation: 2 SOA composites had a combined 350+ revisions. Never lost track of current version, what was deployed on each server, what still needed to be deployed. Simple, but a huge time-saver.
ALLETE Path to Cloud We saw Cloud + DevOps/Automation to pair well Automation is critical, PaaS services removes a lot of administration. Late 2017, licensed Oracle Advanced Security and Oracle Cloud Credits. Using OIC, SOA CS, cloud database, Dev CS, Java CS. Integration group is the main implementer of Cloud Services at this point. DBA group investigating Cloud for DR; some limitations due to pluggable DB. Moving towards Oracle Analytics Cloud.

Oracle Cloud Use Cases Completed Developer Cloud Service Code Repository Java Cloud Service DevOps Tooling (FlexDeploy) SOA Cloud Service Deployed Composite Database Classic SOA CS infrastructure, second DB that deployed composite relies on Oracle Integration Cloud Cloud to Cloud integrations
Big Plans for Hybrid Cloud & DevOps Fully implement Cloud/On Premise Integrations API Platform Cloud Service API Gateway Agent On Premise OIC Connectivity Agent On Premise Oracle Database ORDS REST enable on premise databases Leverage Data Integration Platform Cloud (DIPC) ODI/GG in Cloud Expand use of OIC for simple on-premise integrations Expand use of FlexDeploy Lift and shift SOA composites from on premise to SOA CS Add ODI artifacts to deployments Investigate for database development
Adopting DevOps and Automation has been a big deal, starting with traditional SOA/WebLogic Adopting SOA CS and OIC have been a great step toward a Hybrid Cloud and on premise strategy Adopting DevOps and Automation for the Cloud Services has worked well DevOps maturity to include more advanced CI/CD and the leverage of FlexDeploy Pipelines and Release features. 4Q 2018 and 2019 significant investment in the execution of additional use cases for Cloud/DevOps
