Why should you care about CI/CD

Goal

There should be two tasks for a human being to perform to deploy software into a development, test, or production environment: to pick the version and environment and to press the “deploy” button.

Common Antipatterns

• Deploying Software Manually• Deploying to a Production-like environment Only after

Development is Complete• Manual Configuration Management of Production

Environments

12

Principles of Software Delivery

• Create a Repeatable, Reliable Process for Releasing Software

• Automate Almost Everything• Keep Everything in Version Control• If it Hurts, Do it more frequently and bring the pain

forward• Build Quality In• Everyone is Responsible for the Delivery Process• Continuous Improvement

Agility and Communication in Action

We follow an agile methodology—the industry standard—to manage your web development, which guarantees fast concept-to-market delivery through short development sprints.

This method allows us to receive feedback from our customers early and often,

while adjusting the scope and direction of the project accordingly.
