Hello!
We have a GAE Java application and are evaluating various alternatives
to Google, as we are not satisfied with their level of support (or
lack of it: several indexes are stuck in the "Error" state,
vacuum_indexes command does not help, and our issue/ticket ignored for
days - nothing we can do, basically, to rectify the situation).
AppScale thus seems a good choice - API-level compatibility (we use
only the datastore and the memcache) and open source (thus we won't
_need_ any formal support, theoretically - with controlling the
infrastructure and having access to the source, we can eventually
solve any issue ourselves, as opposed to the current situation when we
have to pray somebody in Google will deign to look at our issue).
Thus I have a couple of questions:
1. are there any performance benchmarks that would say, for example,
that X number of Y EC2 instances handles Z throughput? I've seen
somebody mention 2GB memory requirement - so how many 2GB instances
are needed (for redundancy), and what their throughput will be? What
if we plan to scale to 100 req/sec? 1000 req/sec? 10,000 req/sec?
Basically, we can easily determine the throughput of a "standard"
solution and need to estimate the costs of using AppScale with our
existing code vs re-writing the server side of our app and using a
bunch of off-the-shelf components (e.g. nginx+jetty+mysql).
2. are there any real-world apps/services running on AppScale? Any
security issues found? I couldn't find any references on your web
site.
Best regards,
MG
