A business has an application that consists of five independent AWS Lambda functions.
The DevOps Engineer has built a CI/CD pipeline using AWS CodePipeline and AWS CodeBuild that builds, tests, packages, and deploys each Lambda function in sequence. The pipeline uses an Amazon CloudWatch Events rule to ensure the pipeline execution starts as quickly as possible after a change is made to the application source code.
After working with the pipeline for a few months, the DevOps Engineer has noticed the pipeline takes too long to complete.
What should the DevOps Engineer implement to BEST improve the speed of the pipeline?
A . Modify the CodeBuild projects within the pipeline to use a compute type with more available network throughput.
B. Create a custom CodeBuild execution environment that includes a symmetric multiprocessing configuration to run the builds in parallel.
C. Modify the CodePipeline configuration to execute actions for each Lambda function in parallel by specifying the same runOrder.
D. Modify each CodeBuild project to run within a VPC and use dedicated instances to increase throughput.
Answer: C
