On December 5, Microsoft announced its second Azure Storage price cut of this year. Effective December 12, Microsoft is cutting prices of both geo-redundant and locally-redundant storage by up to 28 percent, according to a post on the Windows Azure blog.
(As the Softies explain in the post, "Windows Azure Storage accounts have geo-replication on by default to provide the greatest durability. Customers can turn geo-replication off to use what we call Locally Redundant Storage, which results in a discounted price relative to Geo Redundant.")
Here's the new post-cut price list, courtesy of Microsoft:
So with this cut, which service is cheapest of them all, when it comes to storage? It's hard to say.
Mantri created a simple calculator to try to help users determine whether Microsoft or Amazon was the low-cost winner. He noted that transaction costs (costs incurred based on number of transactions performed against each service); storage costs (costs of data stored in each service calculated in GB); and bandwidth costs (costs incurred based on data sent from the datacenter) all needed to be factored in.
One reader mentioned to me in an e-mail exchangethat ACS (access control services) was officially priced at $1.99 per 100,000 identity transactions. He said it has been available for free as part of a promotion for for more than a year.
