As a nitpick: Cloud Foundry isn't a company, it's an opensource project.
Lambda isn't, uh, quite as fully featured as Heroku or CF yet. And it ties you very closely to AWS. With Heroku you have a reasonable shot at migrating to Cloud Foundry or vice versa.
Disclaimer: I work for Pivotal, we're the major donors of engineering to Cloud Foundry. We sell a commercial distribution (PCF) and have a public service (Pivotal Web Services).
