Overall Satisfaction with AWS Lambda

We use Lambdas as the primary deployment mechanism for our APIs. It provides flexible ways to deploy without worrying too much about infrastructure, server resilience, or load.

Pros

  • It scales automatically with demand.
  • It reduces operational overhead significantly.
  • It integrates seamlessly with other AWS services.
  • It provides easy ways to deploy and get to prod.

Cons

  • Cold starts are still a pain sometimes.
  • Deployment can feel clunky. The zipped files can still become really bulky and fail.
  • Local debugging isn't always straightforward; it's challenging to set up on my machine for dummy Lambda instances.
  • Less server stuff to manage probably saves some cash.
  • Scales itself, so we aren't paying for idle servers all the time.
  • It's quicker to get things out there, so we can focus on the product roadmap instead of deployment.
Pretty straightforward, deploy the compressed codebase and have an entry point, and it works as advertised. Deployments are mostly simple: zip, upload, define a handler. While it works for most basic to moderate use cases, it is very costly.
It's fine, it works as the others would have, except EC2. We are migrating back to EC2 for dedicated compute because we have scaled to a point where we have consistent traffic. The tradeoff of maintaining infrastructure in-house outweighs the benefits of moving quickly through our roadmap.

Lambda excels at event-driven, short-lived tasks, such as processing files or building simple APIs. However, it's less ideal for long-running, computationally intensive, or applications that rely on carrying the state between jobs. Cold starts and constant load can easily balloon the costs.
