What should one not run on Cloud Foundry?

[hmalp...@gmail.com]

I have been trying to run Elasticsearch - a java search engine and database - on run.pivotal.io for the last couple of weeks.

Support's answer to the current blocker was in fact that I'd be better off running it on a IaaS because it is a data-service; not an application:

http://support.cloudfoundry.com/entries/24469701--ulimit-n-how-to-increase-the-limit-of-files-opened-above-16k

Is this a definitive answer?

Elasticsearch was very close to being good enough on Cloud Foundry for my case:

- Small datasets

- Not highly available,

- S3 backups that are real-time enough; we did get to a few million records and it survives restarts.

- a handful of tenants per installation: no big deal if it fails.

In fact when I move to running ES on EC2 I have to support a big cluster for many tenants: now it must not fail.

The line between app and data-service is grey.

Take docker.io's examples: python, nodejs, redis, sshd, couchdb;

So where do we draw the line?

Thanks,

Hugues

As can be seen here Elasticsearch is a service. 

CloudFoundry in my opinion is for running apps. Which is your special code which is different from my special code.

A service is a dependency is shareable. My elasticsearch is similar to your elasticearch (apart from the data in it).
