AWS Certified DevOps Engineer - Professional

DevOps professionals need to understand how infrastructure changes can be tested, reviewed, deployed, and maintained through automated workflows.

Automation in AWS DevOps

Automation is central to professional-level DevOps practices. Manual infrastructure and deployment processes can become difficult to manage as organizations grow.

AWS services can be used to automate application deployment, infrastructure provisioning, scaling, monitoring, backups, and operational responses.

Automation can reduce human errors and allow teams to focus on higher-value engineering activities.

For example, an automated pipeline can retrieve source code, build an application, run tests, deploy the application, monitor the deployment, and trigger a rollback if required.

Deployment Strategies

DevOps professionals need to understand different application deployment strategies. The appropriate strategy depends on application requirements, risk tolerance, user impact, and infrastructure design.

A rolling deployment gradually replaces older application instances with newer versions.

A blue-green deployment maintains separate environments and shifts traffic between application versions.

A canary deployment gradually releases a new version to a small percentage of users before expanding the deployment.

These approaches can reduce deployment risks and provide controlled ways to introduce application changes.
