as Andrew mentioned, Azure Storage and SSDS are very BigTable like. SSDS seems to have more querying capabilities but I guess we'll have to test the performance. Both can also store blobs up to 50GB in size.
Worker Roles are nice, long running processes that are fed by a queue. Web Roles (like GAE request handlers) can feed the queue for off line or async processing. this mixed model of execution is missing from GAE (and was not on the roadmap either) .Net Services - Access Control and Workflow are nice features as well some questions: performance - really can't comment until I test it but how fast the datastore works is really my biggest concern indexing - how will they handle the same "exploding index" problem that GAE has. Is it automatic (seems to be)? SSDS looks like it can query using inequality/group/sort operators, hopefully on multiple entity properties VM caching/startup - WebRoles/WorkerRoles have dedicated physical cores associated with them but it is unclear how Azure will auto-scale your instances. (the CTP will not have this, its controlled via config file). Cold startups of GAE instances are becoming an issue for me as more modules need to be loaded (lazy loading as much as possible too). How will Azure handle this? Will your .Net apps be pre-jitted/ optimized before upload? How often will they be swapped out of the fabric? If you can maintain a minimum number of instances, how would we be charged for idle time? In GAE, it would be nice if we could keep several instances active pricing - the whitepaper says per CPU/Storage/Bandwidth, so very GAE like. I would assume the pricing between the two will eventually be the same another interesting though is that Azure runs any .Net runtime language so in theory, you should be able to port the GAE stack to IronPython and have it run on Azure. this would likely take a large effort to build the abstraction layer but having a secondary cloud infrastructure to run apps on would be nice MS seems ot have been working on this for awhile (a couple years) so it might actually be workable at V1. cheers brian On Oct 27, 3:12 pm, "Andrew Badera" <[EMAIL PROTECTED]> wrote: > Or, if you're talking about SSDS (SQL Server Data Services) already, be > aware, they're a BigTable clone ... > > On Mon, Oct 27, 2008 at 3:03 PM, jeremy <[EMAIL PROTECTED]> wrote: > > > I'm only skimming the description but i think the more familiar > > relational sql storage will appeal to many people. > > > On Oct 27, 11:16 am, "Andrew Badera" <[EMAIL PROTECTED]> wrote: > > > So, what's the GAE take on the MS Azure announcement at PDC today? > > > > Is it going to be competitive, or not even in the same ballpark? > > > > Will it force the GAE team to spend extra effort on a .NET implementation > > > for GAE? > > > > Thanks- > > > - Andy Badera > > > - [EMAIL PROTECTED] > > > - (518) 641-1280 > > > > -http://higherefficiency.net/ > > > -http://changeroundup.com/ > > > > -http://flipbitsnotburgers.blogspot.com/ > > > -http://andrew.badera.us/ > > > > - Google me:http://www.google.com/search?q=andrew+badera --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
