Question

As a Site Reliability Engineer, you work on building and running large-scale, distributed, fault-tolerant systems in the cloud using automation. You have just replaced the company's Jenkins-based CI/CD platform with AWS CodeBuild and would like to programmatically define your build steps.

a) Implement Jenkins for CI/CD

b) Define build steps manually

c) Automate build steps using AWS CodeBuild

d) Optimize fault tolerance in distributed systems

Answer 1

The question is about automating build steps using AWS CodeBuild after transitioning from Jenkins. AWS CodeBuild allows the creation of configuration files for automated build processes as part of CI/CD pipelines. This ensures efficient and fault-tolerant builds in cloud-based distributed systems.

Step-by-step explanation:

The question pertains to utilizing AWS CodeBuild for programmatically defining build steps within a cloud environment, having shifted from a Jenkins-based CI/CD platform. When aiming to automate build steps using AWS CodeBuild, you'll leverage configuration files to set up your environment and build sequences. AWS CodeBuild is a managed build service that compiles source code, runs tests, and produces software packages ready to be deployed.

In contrast to option a) 'Implement Jenkins for CI/CD' or b) 'Define build steps manually,' choice c) focuses on harnessing automation with AWS CodeBuild. Regarding option d) 'Optimize fault tolerance in distributed systems', utilizing AWS CodeBuild would contribute to fault tolerance due to its managed nature, reducing the risk of human error in the build process and providing higher availability.
