I’ve used https://github.com/kaihendry/count to “experience” various managed compute solutions aka Serverless computing.

AWS Fargate / Elastic Beanstalk is excluded because it does not scale to zero since it requires an underlying compute cluster which you pay hourly for.

Feature	Serverless framework (AWS)	Apex Up (AWS)	SAM (AWS)	Functions (GCP)	Cloud Run (GCP)	Functions (Azure)
Local to Singapore	Yes	Yes	Yes	No (Hong Kong)	Yes	No (Hong Kong)
My subjective DX rating	OK, custom entrypoint	Favourite	Bad, custom entrypoint	Bad, custom entrypoint	Great, but slow	Confusing, but once setup ... OK
Demo URL	AWS SG	AWS SG	AWS SG	GCP HK	GCP SG	Azure SG
Iteration speed	~30s	~10s	~30s	~2mins	~2mins	~30s [1]
Custom domain	Yes, via a plugin	Yes	Yes	Via Firebase [2]	Yes [1]	Yes [2]

[1] CLI will say it's "done", though I suspect the Cloud is being eventually consistent... leading to some confusion when expected changes are not live!

[2] No CLI / IaC option AFAICT

I’ve noticed deployment failures can happen when:

• gcp-cloudrun when there is the same version
• gcp-functions if it’s already deploying

Apex Up is the clear winner to me. Apex Up has the fastest iterations to the cloud (~2s), a fantastic DX CLI with logging that’s easy to use. Apex Up also automatically bundles static/ assets which the others don’t do and uses the standard http request / response API.

To experiment in further public clouds with managed compute, the serverless framework does seem to have the best starter templates with serverless create -h to view them.

Note about iteration speed

There are three types of iteration speed:

1. Local development speed, speed of live reloader like entr. Painful with functions that do not use HTTP req/res interface.
2. Using your serverless tooling to time make deploy and view changes on the Cloud endpoint.
3. Time for your CI/CD pipeline (Github action) to deploy (often much longer since env is setup from scratch)

Iteration speed above is case 2.

I do not consider the time for the initial setup / IaC provisioning which can take quite a bit of waiting, especially for the custom domain!

Price?!

Unfortunately it’s quite tedious and difficult to compare the price, especially when there is a free tier. Just know that I’ve not noticed an impact on my bill when using serverless. It’s must cheaper than paying hourly. If it becomes expensive, you have options!
