AWS Certified Developer Associate DVA-C02 Practice Question
Your team is deploying a web application on AWS Elastic Beanstalk and you are responsible for selecting the instance type. The application has a steady traffic pattern and primarily serves static content, which requires minimal compute power. Initially, the application is configured to use t2.medium instances. However, after monitoring, you notice the instances are underutilized. Considering cost-optimization and application requirements, which instance type should you switch to?
The correct answer provides a cost-effective instance type that meets the needs of a low compute power application while avoiding over-provisioning. A t3.micro instance is a burstable performance instance that provides a baseline level of CPU performance with the ability to burst CPU usage at any time for as long as required. It is suitable for applications with a low steady-state workload but occasionally need to burst. m5.large and c5.large instances are designed for applications that require higher compute resources. Using such instances for a low compute power application would lead to unnecessary costs. t2.2xlarge offers higher CPU and memory compared to t2.medium but would be excessive for the given scenario and therefore not cost-effective.
