Google app engine and lock-in

[Emmanuel Mayssat]

I am aware of AppScale

http://appscale.cs.ucsb.edu/

But is the backend (database) of google app engine also supported?

If so which one is it?

(AppScale support memcachedb, cassandra, mysql, mongodb, and a few others)

Its the other way.

AppScale emulates the datastore of AppEngine - by providing a
compatible API, but implements it with a range of other database
products in the backend.

Just like the SDK emulates it using SQLite. The SDK doesnt have access
to instance of the datastore, but it allows AppEngine apps to run
anyway.


The datastore itself, is Google propriety, so you cant run "it"
elsewhere, but can run applications designed for it elsewhere.

If your app runs in under 20gigs of data, and under 10 instances you have
options. You aren't going to do 100 instances and Terabytes of data.

Sounds interesting... Any idea about the costs ?

Wrt lock-in, at JBoss/RedHat we're working on this new project:

I'm just about to do initial Beta1 release in the next few days.
Perhaps give it a spin and let us know any feedback.

Deployment and setup wise there are no costs, as it's all open source,

hence you can build and maintain it yourself. Not that I suggest that -- we make our $ out of support. :-)

But obviously if you need any serious environment, you'll need some hardware.

But a note of warning, this is a new project, hence not yet around at all - just about to do initial release,

and we definitely welcome community participation.

Otoh, we take big pride in testing things, and we do try to think scalable all the time.

Things are implemented to run in a cluster / cloud, while we admit there are some design issues we need to re-evaluate.

I'll push some announcement blog on Monday,

with more detailed instructions and binaries on how to use things.

I suggest you give it a spin and let us know.

Great news !

Does any hosting solution based on CapeDwarf exist or is planned ?

[Emmanuel Mayssat]

I am using python.

I assume Cape Dwarf is for the java version of the app engine, isn't it?

Yes, Java only.

Unfortunately there is still too much stuff to do on Java side,

to be thinking about Python support atm.

Which doesn't mean community / users cannot contribute this. ;-)

Glad to see another alternative to appengine lock in.

Is there a grid that shows the GAE components supported/partially supported/non-supported by Cape Dwarf?
I see that there is a Channel API sub-tree that says 'Initial @Category support." without much meat behind it.

The API matrix is on the main project site:

* http://www.jboss.org/capedwarf

I see that there is a Channel API sub-tree that says 'Initial @Category support." without much meat behind it.

That's the msg from last commit in that sub-tree. :-)

There is initial support; we have chat demo/example app working.

I suggest you ping us on our forum for more detailed questions / help.
