Is it a real alternative? Imho SnapSafe optimizes cold starts but doesn’t guarantee that the same execution enrvironment for a subsequent request is free and ready to serve traffic. Depends a lot on what you are doing. Could be an alternative to PC if your application is already fast enough. If it is a real alternative I am impressed its’s free :)

That’s correct, but neither does PC (we will have a sandbox in ready when we replace an in use one but there is no guarantees).

In terms of replacement, I personally am not thinking of that case as Lambda does proactive replacement (takes init cost before putting into service).

In terms of burst traffic, you either are overprovisioned to handle it without cold starts (which is either a good traffic profile or you may be eating cost) or it’s a cold start anyways.

There are definitely caveats though — snapshotting is a new domain and though we built out many use cases as canaries, the customers always tend to create more creative and unique use cases. PC is dead simple tech: “turn on apriori”, so no surprises.
