Bernd Harzog recently wrote about Microsoft’s Three Pronged Windows Azure Strategy – particularly with reference to the Service Provider offering. I’ve now had a certain amount of time to reflect on the announcement and try and work out what is going on and it doesn’t seem to constitute a wholehearted strategy to put resellers on a level playing field with Microsoft.

Organizations practicing agile development face many decisions when moving to the cloud.

So who really is the tenant within a multi-tenant environment? It appears multiple definitions exist and if we cannot define Tenant, then how do you build secure applications that claim to be multi-tenant? Continue reading Multi-Tenancy: Who is the Tenant?
