Costly, error prone manual processes and efforts

CHALLENGES

Upgrade risk due to managing multiple application

configurations and versions across servers

Slow deployment to development and test

environments leave teams waiting and unproductive

Delivery Challenges

Today’s business and technical needs are pushing traditional delivery approaches to the breaking point

“At some point, you take a step back, and you realize you have an awful lot of siloe’d systems that are limiting transparency across strategic projects”.

Test and Ops teams have increased pressures to keep up with increased loads but continue to use waterfall approaches and traditional tools.

§  Automate deployments to test environments (Int, QA, UAT etc.) – Generate confidence in the applications and your ability to deploy

– Remove human variability – Fine granularity of deployment

Develop, integrate, build, deploy and test in small work packages

§  Test in production-like environments – Use virtualized environments for testing but also use real databases, queues, host systems etc.

§  Document the strategy – automatically – Provide a full audit trail of all deployments including the content and operations used

§  Treat deployment as a part of the development lifecycle – Not ‘something done by someone else’

– Architectural awareness

A Continuous Delivery Pipeline

Development Testing Staging Production Business Owners Customers

§  Validate on more production-like conditions earlier

§  Automate hand-offs/promotions to increase velocity through the different stages

§  Standardization on processes and assets between Dev and Ops

§  Automated monitoring and dashboarding of quality and performance against service level agreements at multiple stages

Ensure applications are production-ready throughout the lifecycle and can be released at any time while minimizing rollback due to quality issues
