Mark Rendell – Accenture
DevOps Control Services Centre
A globally networked pool of resources
providing projects the option to have key areas of
their DevOps delivered as a service. By
emphasising Continuous Delivery, we are able
to vastly improve your Software Delivery
Lifecycle at all each stages including
Transformation, Mobilisation and
Assessment
Software Configuration
Management
Release Management
Assessments
Environment Management
We can…
1. Take a project from a standing-start to a
working Development and Tools
infrastructure in days
2. Increase Agility by using our pioneering
methods for Continuous Delivery
3. Increase productivity and predictability
through fully automated environments
4. Reduce Cost by using proven
processes and expertise to reduce
errors and downtime

• Where we store code, configuration, binary artefacts etc.
• The workflow for doing CD
• Moving code around (build / deploy)
• Hooks for automated quality gates

Absolute environment consistency required!
Should use CD for platform / infrastructure code as well!

13.  Many different (micro) services
 Lots of test environments (for different service teams)
 J2E Servlet Containers, Message Queues, RDBS, NoSQL, Caching
 Support for Continuous Delivery (eventually Continuous Deployment)
 Auto-scaling
 High-availability
 Cloud provider independence
Requirements of our Platform

14. A first class native concern
Orchestrated by Jenkins so good central hub
Deployment automation native to Cloud Foundry
For Cloud Foundry supported application packages, native to
the platform application, very convenient, fully abstracted
and optimised
Cloud Foundry (Bosh) managed for natively supported
application packages
We extended Bosh for other packages
Natively managed by the Cloud Foundry
Fully automated by calls from the above layer
Fully abstracted from us
Our Cloud Foundry-based Solution
 Auto-scaling
 High availability
 J2E Servlet container, Message bus, RDBS, NoSQL, Caching
 Many different (micro) services
 Lots of test environments (for different service teams) Support for Continuous Delivery (eventually Continuous Deployment)

 Cloud provider independence
