Cons
Con Slow deployment
The deployment process with AppFog is generally nice and easy because of its CLI. Unofrtunately the only downside of that process is the fact that it takes too long. A deployment to AppFog genereally takes up to 40 seconds, which should be fine if you are deploying once a week, but when you deploy every hour it starts bothering you too much.
Con Slow deployment process
The deployment process in Modulus can be slow depending on the size of the project. On every deploy the whole application is bundled (except node_modules
and deployed to Modulus. Since it doesn't use something like git it has to upload every file on each deploy instead of "diffing" them.
