When should you choose EC2 over alternatives?

Summary

Choose EC2 when you need OS-level control, custom agents, specialized runtimes, long-running processes, or migration compatibility with existing server workloads.

Longer Answer

EC2 is best viewed as virtual-machine compute with full OS and networking control. It fits when the workload characteristics align with its strengths rather than when a team simply defaults to a familiar service.

For this question, mention the business and operational drivers: control, scaling shape, security boundaries, cost model, and how the service integrates with ALB, NLB, ASG, EBS, EFS, SSM, IAM, CloudWatch, Route 53, Secrets Manager, and Systems Manager Patch Manager.

Key Points

• EC2 is best viewed as virtual-machine compute with full OS and networking control
• It fits when the workload characteristics align with its strengths rather than when a team simply defaults to a familiar service
• For this question, mention the business and operational drivers: control, scaling shape, security boundaries, cost model, and how the service integrates with ALB, NLB, ASG, EBS, EFS, SSM, IAM, CloudWatch, Route 53, Secrets Manager, and Systems Manager Patch Manager
• For 'When should you choose EC2 over alternatives?', interviewers are looking for a decision process: state the requirement, name the AWS mechanism, describe the limit or failure mode, and explain how you would verify it in production.
