• #16: On-premises AND Cloud: We believe in a world where you’re integrating public cloud with your on-premises infrastructure, and using each where it makes sense, in conjunction with each other. Think and, not or. It’s not an on-premises OR cloud proposition – it’s an AND proposition. And when we say integration, we mean true integration – across infrastructure, apps, identity, and databases. This is what we call hybrid. Microsoft is the only company which has the necessary assets across virtualization, identity, data platform , development and management to provide a consistent experiences across on-premises, our cloud and 3rd party service providers. This vision and strategy - called “Cloud OS” – is what we aim to deliver for our customers. If you choose look at other Cloud vendors that provide public OR private cloud offerings (Amazon, VMware, or Google), you have to cobble together disparate offerings and you will not get a seamless experience.
• #18: Store, Backup, Recover   Let’s first understand why Cloud makes for a great storage option? A typical organization increases their data storage by 50-60% every year (source:IDC). But only a small portion of the data is frequently accessed or used. So using purely on-premises storage like SAN/NAS solutions for that data is expensive. Forrester’s study placed a cost of about $95 per GB of data per year for an on-premises SAN solution which is 4X the cost of putting a GB in the Cloud. Of course, not all data  can be put in the Cloud for performance or compliance reasons but where you can, using Azure for all backup and archived data, as well as less frequently accessed primary data makes a great business case.  
• #19: We make 3 copies of data for durability and availability. So if a rack or server goes down, you data is available and accessible. We provide 99.9% SLA for storage. Windows Azure Storage system is the underpinning to everything in Azure that requires storage. The Windows Azure storage system provides a solid robust data platform for different services that make use of it – Blobs, Tables and Drives. Use Blob service for storing large amounts of unstructured data that can be accessed from anywhere in the world via HTTP or HTTPS. A single blob can be hundreds of gigabytes in size, and a single storage account can contain up to 100TB of blobs. Common uses of Blob storage include: Serving images or documents directly to a browser, Storing files for distributed access, Streaming video and audio, Performing secure backup and disaster recovery, Storing data for analysis by an on-premises or Windows Azure-hosted service Tables is a NoSQL datastore which is ideal for storing structured, non-relational data. Common uses of the Table service include: Storing TBs of structured data capable of serving web scale applications, or storing datasets that don’t require a full fledged relational DB. Drives are what are attached to VMs. They automatically provide get the same durability and availability. This differentiates us from other competitive offerings (like AWS) that have less reliable and durable storage systems for their VM instances.
• #20: Additionally, data is asynchronously copied to another datacenter that’s at least 400 miles away. So you can be sure that every piece of data that you store in the Azure Blob is available as well as protected against regional disasters (we call this geo-replication).   Geo replication is a unique feature, that differentiates us from competition.
• #21: Typically large data sets take a very long time to upload or download over a network; For example, with a network 10 TB of data will take at least one month to upload over a T3 line. With Windows Azure import/export , this problem is eliminated. Import/Export enables you to move your large dataset to the Azure cloud more efficiently than over your network. Similarly, you can use this service to export data that you need to recover: we download it at the Microsoft Regional Datacenters, and ship it back to you. According to a recent survey, (source: Forrester) 49% of those surveyed plan to move their data or already have moved their data storage to the cloud, citing both cost reduction and flexibility as reasons to move storage into the cloud. 80% of IT decision makers in a recent study cited that encryption in transit was of critical or high importance. (source: Forrester) A Forrester study also estimated a cost of about $95 per GB of data per year for an on-premises SAN solution which is 4X the cost of putting a GB of data into Azure.
