1. Can my database auto-scale?
2. Can my JVM heap auto-scale beyond 2 GB without GC pauses?
AWS never fit into my definition of a "cloud" solution. It's a VPS with a rich API and a lot of addons (load balancer, EBS, S3...). From what I'm reading, Beanstalk changes this and clearly puts AWS in the category they've long claimed to be in. Not that their service wasn't great/unique before. This just puts them that much further ahead. It's along the lines of what Heroku does with their routing mesh layer (as far…
What's your definition of a "cloud" solution?
a lot of "cloud" services these days are nearly identical to VPS services of yore, with the added new ability to create/destroy VPS nodes whenever you want. very few of the big "cloud" providers actually handle auto scaling (as it's difficult in a world where all apps are not made the same).
I'm not sure how useful this really is. It just handles the application layer, leaving you on your own for dealing with the database. Now, Amazon has some services to help you out (RDS, SimpleDB), but SimpleDB is kind of crap, and RDS is expensive. More importantly, that loses some of the simplicity, meaning that you still have to think about infrastructure to a degree. Heroku is git push to deploy, and if you have a…
Ignoring provisioned storage and request costs one can have a small on-demand RDS instance for ~$80/month. Heroku's instance (RAM/CPU) equivalent (Ronin) is $200/month.
Just to be clear, this is only for Java apps right? This does not include PHP or Python?
If you wanted something similar for Python or PHP then you could use VMWares VApp stuff which gives you the PaaS solution on top of hardware hosted by Colt which gives you the IaaS solution.
The reason that the VMWare offer gives you Python, PHP or other stuff, is that under-the-hood VMWare are using Chef and you can run your own custom Recipes, hence you could deploy whatever you want as a managed platform... though you would lose the Eclipse right-click deploy (though honestly if you're deploying from CI you're probably not going to be using this anyway).
Edit: It being almost impossible to just find simple and clear documentation on the VMWare site, this is the info link I've managed to unearth: http://www.vmware.com/products/vcloud-director/overview.html
The key point is that you could create a virtual datacenter, hosted with a 3rd party like Colt, and then use Chef to manage it as a platform, and deploy directly to it as if you owned your own "Elastic Beanstalk".
As an aside, I for one am getting tired of the never-ending list of acronyms and strange product names that are coming out from every vendor.

automatic scaling would be a good benchmark for the true definition of cloud. a lot of "cloud" services these days are nearly identical to VPS services of yore, with the added new ability to create/destroy VPS nodes whenever you want. very few of the big "cloud" providers actually handle auto scaling (as it's difficult in a world where all apps are not made the same).

You can do this with EC2. You can set up monitors based on CPU usage over a time period and it'll start new nodes if required.
S3 is 'autoscaling' for serving files. Just upload your files and pay for what you use.
Wow. The benefits of Google App Engine without the limitations? Sure, an app on GAE is probably cheaper in terms of monthly expense, but factor in the development costs for a Java team unfamiliar with App Engine and Beanstalk is probably a far better investment.
