lambda is great for three things: - scaling to zero for low use services - reliably managing other infrastructure, like pools of ec2 or ephemeral ec2 spot - getting 1000 cpu cores for 5 seconds to do latency sensitive data heavy lifting the elephant in the room with cloud is always egress bandwidth billing. egress heavy apps just shouldn’t live on aws. for me, the fun with aws is not figuring out how to make cloud lasagna and then write thought leader blogs about how tasty it is, but in understanding which parts of aws are actually better than alternatives, and how to compose them into good systems. s3, dynamo, ec2, ec2 spot, lambda, r53. egress bandwidth aside, these things are for great good. add in cf workers+r2 for egress bandwidth heavy components.
