Microsoft Starts Charging For Windows Azure

It's hardly a new issue: Developers have been talking about this since last July when Microsoft revealed its pricing model for Azure. But with Microsoft now going up against established cloud computing competitors such as Google, and Amazon, it could impede Microsoft's progress in the market.

With Azure, Microsoft charges 12 cents an hour for 'compute time,' which means that even a small Azure instance costs around $86.40 per month, plus storage and bandwidth charges. According to Roger Jennings, an independent .Net developer and principal consultant of OakLeaf Systems, Oakland, Calif., this locks out very small, low traffic Web sites that typically use much cheaper shared hosting options.

On Microsoft's Windows Azure forum, developers have been clamoring for a small business- focused Azure subscription option that would lower the fixed costs involved. Another popular suggestion is for Microsoft to offer developers a limited, free Azure option to give them more time to get up to speed on the platform.

Jennings, who's been asking Microsoft to consider this for months, says the move would make Microsoft more competitive with Google App Engine, which currently includes a limited free option for testers. But while this would help Microsoft get more developers onto Azure, it wouldn't necessarily equate to more paying customers and revenue, he notes.

Microsoft is offering an Azure promotion for customers that are willing to sign up for a six month subscription. For $59.95 per month, developers can get 750 hours of Azure compute time, 10 GB of storage, and one million storage transactions, along with 7 GB of inbound data transfers and 14 GB of outbound data.

What's odd about the Azure pricing issue is that Microsoft has anticipated and addressed the other big questions customers initially had about Azure.

One of the first was how cloud-based applications would work with existing on-premise software investments. In response, Microsoft built Azure templates into Visual Studio 2010 to make it easy to move code between cloud and non-cloud applications. Project Sydney, now in beta and slated for launch this year, securely connects applications running on premise with applications that run in the public cloud.

"Microsoft has made it pretty easy for developers to dive into Azure," said Michele Leroux Bustamante, a Microsoft MVP for Connected Systems and chief architect with IDesign, a Los Gatos, Calif.-based software consulting firm. "The templates that support the Visual Studio experience kick start your development efforts, and you can also test Azure applications pretty effectively using the local Development Fabric before publishing to your Azure account."

From a technology standpoint, Microsoft is showing that it's able to anticipate key areas of need for customers. Now it's time for the marketplace to decide whether the Azure pricing model makes sense.
