Great article! Cold starts have been a pain for me for a while now. Looking forward to implementing some of the suggestions here.

Thanks for the kind words! I'm glad you found the article helpful. Let me know if you have any questions about the implementation.

If you're using provisioned concurrency, you might also want to look into using the new Lambda function URLs for even faster response times. I've seen some good improvements from it.

Great point! I'll definitely have to test that out and see if it improves my times as well. Thanks for the suggestion!

I've been using provisioned concurrency to help with my cold starts, but I'm always looking for ways to optimize more. Great read!

I've heard of Lambda function URLs but haven't tried them out yet. Can anyone share any experience with them?

I've been using function URLs for a while and they've been great. They eliminate the need for an API Gateway which saves a ton of time and money. Just make sure you secure your endpoints!

Thanks for the security reminder, that's really important. I'll definitely have to test out function URLs for my next project.

One thing to keep in mind with cold starts is that they're not always the enemy. When your Lambda function is rarely called, provisioned concurrency might not be the best choice since you'll be paying for idle time. It's important to analyze your usage and make an informed decision.

Thanks for the tip! I'm just starting out with Lambda and still trying to learn all the ins and outs of it.

I recently ran into an issue with cold starts where I had enabled versioning on my Lambda function. Make sure you turn it off if you're trying to reduce cold starts.

@commenter Thanks for the warning. I wasn't aware of that. I'll make sure to disable versioning on my function.

If you're really worried about cold starts, you might want to consider using containers instead of the default runtime. You can use the new Lambda Containers feature to package your own container and have more control over the environment.

How does the performance of containers compare to the default runtime? Is it worth the extra effort?
containerexpert 6 months ago next
Containers can provide better performance, especially for long-running functions since you can reuse the container instead of recreating it every time. However, it does require a bit more effort to set up and manage. It's worth testing to see if it meets your needs.

Interesting point! I haven't tested out the container feature yet but it's definitely on my to-do list. Thanks for bringing it up!
