I’ve just started experimenting with Lambda. One of my motivations is to cut down on the AWS EC2 resources that I’m using.
As it turns out, image display over a slow link (an iPad on a 10Mb Internet connection) can have a big impact on the web server. So I’ve been thinking that it would be great to move image display to Lambda.
What I’m worried about is the start-up lag of the HTTP process on Lamda. I know that Lambda can keep processes “warm”. Is this something that Amazon charges you for (you are, after all, using compute and storage).
