An open source multi-tenant framework for Azure cloud

We developed a Multi-Tenancy Framework for partners who want to realized multi-tenancy but 1) don’t want to make change on their current single tenant design, or 2) want to keep high level of isolation between tenants, so that to use local cache and allow per-tenant customization, which is only achievable in on-premise environment before. We originally developed this for two of our managed partners. Then, we decided to make it open source, so that everyone can benefit from it.

It is available now at http://cloudsamurai.codeplex.com/ . We just released v0.9 yesterday. Welcome to try and feedback.

How to do QA and test in Azure (4)

·         Auto-deployment Tool is very important

o    Save lots of time, test quickly

o    Confidence in testing environment, focus on features

o    You also gain confidence in the deployment tool, which allows you to deploy more often, and faster.

·         Small Release, More Often Release

o    Integrate customer feedback into bug fixing

o    Drive better customer experience

o    Drive cost-per-release down

o    Release often. How often? One release every month/week/day ?

·         "One week" worked for some web sites.

·         In reality, this should simply be as low as is practical and useful for the business needs of the group.

·         We found that the lower we could get this, the more flexibility we had in getting changes out to prod quickly and reliably, getting better customer experiences faster. 

·         In particular, get really fast at verifying that things that haven't changed aren't broken.

·         This will really help with testing things like adopting new versions of the SDK.

o    More-often-and-quicker release is enabled by

·         Good auto-deployment tools.

·         Well documented deployment and troubleshooting processes.

Cloud Computing Notes

About me:

I'm a Developer Evangelist in Microsoft, selling cloud computing technologies to our global software partners.

Personally, I believe in cloud computing and I'm confident in Microsoft cloud computing platform Azure. I had to admit that Azure is not perfect: many features are still missing or immature, and the developer experience on Azure is some times painful. So, I blog here to share experience we gained from real world Azure projects. Some experience may be applied to other cloud computing platforms as well.

In my spare time, I participate in open source projects: http://cloudsamurai.codeplex.com/ and http://cloudninja.codeplex.com/, both of which are about how to use Azure to build cloud applications.

In a sense, I'm lucky that I'm doing a job I like, and I'm selling things I really believe to the people I love.
