Which AWS compute service is the right fit—Lambda, Fargate, or EC2—for different backend needs?

Compares serverless functions, containers, and VM-based services in terms of scaling, cost, and control.

• AWS Lambda is suited for event-driven or intermittent workloads requiring auto-scaling and cost efficiency per invocation. • AWS Fargate deploys containerized microservices without server management, ideal for scalable backend services. • EC2 offers full VM control for legacy workloads, custom networks, and long-running applications. Your choice depends on architecture type—stateless events, container services, or full virtual server control. Tags: aws, lambda, fargate, ec2, serverless, containers, cloud
