Decomposing the monolithic approach into smaller manageable microservices increases the overall complexity of the system

Control multiple delivery pipeline

Managing different technology stacks between different microservices.

Managing the rapid feature changes for several microservices at the same time

5 Automate End-to-end delivery and increasing delivery efficiency in terms of cost and in terms of time

CXSDEM – Optimize your delivery process?

Continuous Delivery – Tooling for highly automated, end-to-end software pipeline

Something Changes• A developer checks in code

for a bespoke software component.

• A COTS Software package requires an upgrade.

• New firmware or configuration is needed for the network.

Solution Progression• Automatic decision to

progress to the next defined environment e.g. Development, Functional Test, Security Test, Performance Test, Scalability Test, FMEA Test, User Acceptance Test, Pre-Live, Production, Live Copy

New Stack Is BuiltThe environmental pipeline orchestration engine triggers a build and test of a new multi-stack environment.• Network Topology Built• Compute Nodes Built• Applications deployed and

configured• End to end acceptance tests

run.

Governance• Tests are automatically

assessed for pass or failure.• Code Quality checks are

applied and enforced.• Test coverage metrics

enforced.

Define User Stories and Requirements as well as test strategy.

Checkout code from SCM and Artifacts Repo and build the project

Execute automatic tests (unit, functional, service level, etc.)

Run automated Code Quality Analysis

Send the packaged module to central artifact repository

Deploy a published package to an execution environment

Officially Release the package.
