Agile Success… And Failure

Agile Context in DevOps

DevOps - DefinedHandshake between Development and Deployment Operations

Developers are agents of change; Operations generally averse to change (system down time, etc…)

Deployment processes may introduce new defects and incompatibilities

DevOps – Impediments to AgilityOperations often involved late in the product development cycle

Time and effort to configure and enable Production-like systems

Conflicting Metrics & Measures

….disrupts flow!

Opportunities for DevOps

If releasing is expensive & risky, we release seldom.

If releasing is cheap & safe, we release often.

LARGE BATCH

SMALL BATCH

Opportunities for DevOps

Utilize Near Production Systems -

Frequently

Validate System

Quality -Continuously

Deploy Frequently

with Repeatable and Reliable

Processes

Rapid Service Virtualization

(Cloud)

Collaboration between

Developers and

Operations Teams

Remember…

One bite at a time.
