EC2 vs Lambda vs Fargate - How to Choose the Right AWS Compute
EC2, Lambda, or Fargate — choosing the wrong compute option costs you money and performance. Here is exactly when to use each one in production.
Frequently Asked Questions
When does Lambda become more expensive than EC2 for the same workload?
Lambda becomes costlier than EC2 when your function runs continuously for more than roughly 20 hours per day. At that point a Reserved EC2 instance is cheaper. Lambda wins for bursty, event-driven workloads with idle time. EC2 wins for steady 24/7 compute.
Can Lambda and Fargate access resources inside a private VPC subnet?
Yes. Both Lambda and Fargate can be deployed inside a VPC by specifying subnets and security groups. The trade-off is that Lambda inside a VPC loses default internet access — you need a NAT Gateway for outbound calls to public endpoints.
