Quick Answer
The answer is Amazon ECS, the correct choice for container orchestration of microservices because it is a fully managed service designed specifically to run Docker containers at scale, integrating natively with Auto Scaling and CloudWatch to automate deployment and demand-based scaling. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your ability to distinguish between AWS compute services: while Lambda handles serverless functions and Elastic Beanstalk offers a platform-as-a-service that can run containers with less granular control, ECS provides the dedicated orchestration layer needed for microservices architectures. A common trap is confusing CodeDeploy, which only manages application deployments, with the orchestration and scheduling capabilities of ECS. Memory tip: think “ECS = Elastic Container Service” for orchestration, not just deployment.
This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company needs to deploy a set of microservices using Docker containers on AWS. The deployment should be automated and support scaling based on demand. Which AWS service should be used to orchestrate the containers?
AWS Lambda
Why wrong: Lambda runs code in response to events, not containers.
AWS Elastic Beanstalk
Why wrong: Elastic Beanstalk can deploy containers but is more opinionated and less suited for microservices orchestration.
Amazon ECS
Amazon ECS is a container orchestration service that integrates with other AWS services.
AWS CodeDeploy
Why wrong: CodeDeploy deploys applications to compute services, but does not orchestrate containers.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon ECS
Option D is correct. Amazon ECS is a fully managed container orchestration service that integrates with Auto Scaling and CloudWatch. Option A (Lambda) is for serverless functions, not containers. Option B (Elastic Beanstalk) can deploy containers but is less flexible for microservices. Option C (CodeDeploy) is for application deployments, not orchestration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Lambda
Why it's wrong here
Lambda runs code in response to events, not containers.
AWS Elastic Beanstalk
Why it's wrong here
Elastic Beanstalk can deploy containers but is more opinionated and less suited for microservices orchestration.
Amazon ECS
Why this is correct
Amazon ECS is a container orchestration service that integrates with other AWS services.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
