You're asking who would pay more for dotCloud vs. DIY on Amazon who themselves have a huge markup on their servers against traditional hosting?

I compared to EC2 primarily because it also has hourly pricing. If I compared to DigitalOcean instead, then DotCloud would look even worse -- about 10x more expensive.

Correct. So who would pay for x when y? Everyone who wants x, not y.

We at OpDemand wish the Flynn crew the best of luck. I expect more Docker-powered PaaS's to sprout up, so I'm glad Solomon and the dotCloud crew are focused so heavily on interoperability. OpDemand will be releasing a very similar open-source project called Deis in the next few weeks. It's an open-source PaaS powered by Docker & Chef, with a Heroku-inspired workflow. We're busy ironing out a few final issues, putting…

Any chance you'll be adding/have Puppet support as well? We have our cart hitched pretty firmly to it at this point. Congrats on the upcoming release!

I'd love to know more about how the cluster will organized. Is there going to be some kind of master controller node, or will it be distributed and self organizing somehow? It almost feels as tho Flynn (or maybe something build on top of Flynn) could/should be a whole minimal linux distribution (SmartOS-ish) that could just boot up into RAM, be told to read a cluster config from somewhere and then start working for t…

Yes, you're on to something. :)

My main problem with Docker is that container IP addresses and MACs are changed after every container reboot. This means I can't have a database in one container and a web app in another because I have no way for the web app to discover the address of the database server. Seems like this would be an issue for the host-only (private) network?

In dynamic clusters like Flynn this could be solved with a naming service. Typically this will be implemented on top of something like Zookeeper or Doozer.

Another option could be to use Go DNS [1] to integrate a DNS server directly into the cluster. This would allow the DNS records to immediately reflect the state of the cluster, using SRV records to map directly to the dynamically allocated hosts + ports. DNS resolver caching would have to be carefully managed though.

I have no idea whether there any plans to implement a naming service on top of Flynn.

Thanks. We're excited to share our take on private PaaS with the open source community.

Re: Puppet -- A good chunk of the "orchestration" is done by updating data bags on a Chef Server, and force-converging Chef nodes over SSH. However I know Puppet has similar constructs, so it's definitely possible to fork the Deis controller and Puppetize it. We'd encourage that sort of contribution.

Does anyone know anything like this (a self hosted PaaS) for .NET? I'd love to use docker or something similar for .NET applications.

If your app works with Mono, there's no reason why you can't use Docker/Flynn: https://github.com/friism/heroku-buildpack-mono

Hi, I'm the founder of dotCloud and author of Docker. Projects like Flynn are the reason we opened Docker in the first place. They are a good thing for the docker ecosystem, and they are definitely good for dotCloud. The dirty little secret of PaaS is that there is not, and will never be a single PaaS that fits everyone's needs. With docker we offer a foundation for many PaaSes to engage in a healthy competition whil…

So what is the strategic business advantage? Is it that Docker (presumably, your core piece of infrastructure) improves as a product as more PaaS's adopt it? So essentially your competition will improve your own infrastructure. Much respect for DotCloud's success thusfar btw.

Not from dotCloud but I've noticed that there is a focus for a central index. It might be possible for them to get revenue from an app-store. There is also the usual consulting that can be derived from expertise.
