Which compute service—Lambda, Fargate, or EC2—best fits backend workloads in 2025?

Compares serverless, container-based, and VM-based AWS compute services regarding scalability, cost, and control.

• AWS Lambda is ideal for event-driven or intermittent workloads—scales automatically and charges by execution duration. • AWS Fargate simplifies running containerized microservices without managing servers—good for apps needing flexible container runtime. • EC2 offers full infrastructure control and is preferred for legacy systems, custom networking, or long-running workloads. Choose based on your architecture pattern, control needs, and operational complexity. Tags: aws, lambda, fargate, ec2, serverless, containers, cloud
