Google today announced that the next version of Android will be named “KitKat,” after the ubiquitous chocolate bars sold around the world. It’s the first time a mainstream operating system has been given a licensed name, and the deal with trademark owner Nestle took time to complete: the BBC reports that Google director of Android global partnerships John Lagerling first called Nestle about the name in late November of 2012, and that the deal was only finalized at Mobile World Congress in Barcelona in February of this year. “We decided within the hour to say let’s do it,” said Nestle executive vice president of marketing Patrice Bula.

Scalability and Performance Targets
Now that we have given a high level description of storage accounts, storage abstractions and how they are grouped into partitions, we want to talk about the scalability targets for storage accounts, objects and their partitions.
The following are the scalability targets for a single storage account:
- Capacity – Up to 100 TBs
- Transactions – Up to 5,000 entities/messages/blobs per second
- Bandwidth – Up to 3 gigabits per second
The 100TB is a strict limit for a storage account, whereas the transactions and bandwidth are the current targets we’ve built the system to for a single storage account. Note, the actual transaction and bandwidth achieved by your storage account will very much depend upon the size of objects, access patterns, and the type of workload your application exhibits. To go above these targets, a service should be built to use multiple storage accounts, and partition the blob containers, tables and queues and objects across those storage accounts. By default, a subscription gets 5 storage accounts, and you can contact customer support to get more storage accounts if you need to store more than that (e.g., petabytes) of data.
It is expected that a hosted service needs up to as many storage accounts to meet its performance targets given the above, which is typically a handful of storage accounts to up to 10s of storage accounts to store PBs of data. The point here is that a hosted service should not plan on creating a separate storage account for each of its customers. Instead, the hosted service should either represent a customer within a storage account (e.g., each customer could have its own Blob Container), or map/hash the customer’s data across the hosted service’s storage accounts.
Commitment pricing for storage capacity for the initial subscription term of six months is as follows:
