3.3. Application Deployment & Operations

For developers, understanding application deployment and operations is crucial for successfully delivering their code to users and ensuring it runs reliably. This phase connects your development efforts to the operational realities of the cloud.

The First Principle is that robust application deployment strategies (e.g., Blue/Green, Canary) and inherent application resilience mechanisms minimize downtime, reduce risk, and ensure continuous availability. Developers play a direct role in designing applications that are deployable and operate well in the cloud.

You will learn about common deployment strategies from a developer's perspective, the importance of rollbacks, and basic concepts of high availability and fault tolerance for applications.

The focus is on comprehending how your application code integrates with these operational best practices, which is crucial for the DVA-C02 exam.

Scenario: You need to deploy a new version of your application to production. You want to minimize downtime and have a quick way to revert if the new version has issues.

Reflection Question: How do robust application deployment strategies (like Blue/Green or Canary) and inherent application resilience mechanisms fundamentally minimize downtime, reduce risk, and ensure continuous availability for your applications in production?
