On 14th of July, during the Microsoft Worldwide Partner Conference 2009, Microsoft officially announced the business and partner model for the Windows Azure platform including service level agreements and support programs.
Upon commercial availability, Windows Azure will be offered through a consumption-based pricing model, allowing partners and customers to pay only for the services that they consume.
– Compute @ $0.12 / hour
– Storage @ $0.15 / GB / month stored\
– Storage Transactions @ $0.01 / 10K
– Web Edition – Up to 1 GB relational database @ $9.99
– Business Edition – Up to 10 GB relational database @ $99.99
– Messages @ $0.15/100K message operations , including Service Bus messages and Access Control tokens
Bandwidth across all three services will be charged at $0.10 in / $0.15 out / GB.
Windows Azure compute hours will be charged only for when your application is deployed so while developing and testing your application you may want to remove the compute instances that are not being used to minimize compute hour billing. Windows Azure storage is metered in units of average daily amount of data stored (in GB) over a monthly period. Storage is also metered in terms of storage transactions used to add, update, read and delete storage data. These are billed at a rate of $0.01 for 10,000 (10k) transaction requests. Bandwidth is charged based on the total amount of data going in and out of the Windows Azure platform services via the internet in a given 30-day period.
At launch offers will be available in local currencies for Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, India, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, UK, and the United States. In the March 2010 timeframe we expect commercial availability to expand to Brazil, Chile, Colombia, Czech Republic, Greece, Hong Kong, Hungary, Israel, South Korea, Malaysia, Mexico, Poland, Puerto Rico, Romania, Singapore, and Taiwan. Additional countries and currencies will be launched as quickly as possible.
