What do people use lambda for generally?
A few use cases - Time taking stuff that happens infrequently and you don’t want your application servers to handle. Eg - processing video files after upload Small independent apis. Eg - If you have a website and want to let people email you, you can set up an endpoint with api gateway and connect it to a lambda which in turn sends an email via ses. Managing your aws infrastructure. Eg - if you want to save costs, you can hook up a lambda to a cloudwatch alarm which shuts down some servers during nighttime. More on reddit.com

July 11, 2021Anyone who have used lambda for something big?
Yes, I do, and I would dread deploying in a more traditional way. I've got about 50,000 lines of python running in about 60 different lambdas. I'm assuming that's what you mean by big. It's complex and featured, but it works with low volumes. But it can scale up easily. E.g. one of my lambdas runs 4 times per minute. The other day I spotted some bursts of 1,000,000 per minute. Amazon didn't even break a sweat. I didn't even notice, and the total cost was about a dollar or so. Compared to a similar app we have on-prem, the cost is about 1/100 as much. Our development speed is much faster too. The real cost saving is in development time, which is far faster when you don't have to worry about scaling, patching, isolation etc. Maintenance is basically non-existant. I don't have to worry about patching, scaling etc. The real work is in the tooling. There are frameworks you can use to make it easy. I've got a home-made one that does packaging, unit testing, integration testing etc. Things like alarming and monitoring become easier. The metrics are all there. (Duration, failure rates etc.) I use most other AWS services with it. S3, dynamo, step functions, SQS, SNS, SES. More on reddit.com

When your template includes one or more dashboards, the page shows your dashboards instead of the default dashboard. You can switch between dashboards with the drop-down menu on the top right of the page. The following example creates a dashboard with a single widget that graphs the number of invocations of a function named my-function.
