Windows Azure Storage now has "over 4 trillion objects stored, process an average of 270,000 requests per second, and reach peaks of 880,000 requests per second."
About a year ago "the Azure Storage hit the 1 trillion object mark. Then for the past 12 months, an impressive 4x increase in number of objects stored, and a 2.7x increase in average requests per second was seen," wrote Microsoft.
The Azure team says, they expect this growth rate to continue, as they lowered the cost of requests to storage by 10x. "It now costs $0.01 per 100,000 requests regardless of request type (same cost for puts and gets)" -- "making object puts and gets to Windows Azure Storage 10x to 100x cheaper than other cloud providers," the team said.
In addition, Microsoft now offer two types of durability for storage - Locally Redundant Storage (LRS) and Geo Redundant Storage (GRS).
"GRS is the default storage that Microsoft always provided, and it provides geo-redundant storage, where we maintain an equivalent 6 copies of your data spread across 2 locations at least 400 miles apart from each other (3 copies are kept in each location). While the LRS is a new type offered at a discount and provides locally redundant storage, where we maintain an equivalent 3 copies of your data within a given location," explains the Azure team.
Microsoft also with the Windows Azure Virtual Machines, provided access to Windows Azure Storage via easy to use client libraries for many popular languages (.net, java, node.js, php, and python), as well as REST.
Also, Microsoft has now "more than doubled the number of available Windows Azure Web Sites Reserve Instances in its East US, West Europe, and North Europe datacenters."
