PURPOSE To introduce you to working with Cloud databases in SQL Azure by working to accomplish a specific goal. I’ve found it’s easier to learn about something when you have a goal in mind.

The Goal Create a Tool in Management Studio that can upload/retrieve common TSQL scripts to/from an online repository.

What is Cloud Computing? A Service approach to computing that’s about scaling, abstraction by the vendor, and consumption-based pricing.

Think “Electricity” Powering your building is like running your website / database

Why use the Cloud? 2 reasons: Scale to and pay for what you use. Only worry about the stuff you know well.

Allocated IT-capacities Load Forecast Not Enough Power Too Much Power IT CAPACITY Slide Objectives: Understand the challenges of irregular load in applications Understand the challenges of both too much capacity and not enough capacity and the sort of groups they impact within a customer Understand that traditionally IT capacity is purchased in a stepwise fashion involving capital expenditure at each point Speaking Points: To understand the value and opportunity for cloud computing, I believe it’s important to think about how IT capacity is typically used by applications today in most environments. Today most organizations significantly over estimate or underestimate the amount of resources they need to run their applications. This leads to a higher cost for the infrastructure and the delivery of the overall applications. Build Steps: Forecast load is to grow steadily Planned capacity grows in a stepwise fashion. Need to plan in advance due to hardware lead times Actual load is highly variable over time Periods where we have excess capacity. Capital laying idle, opex wasted powering and cooling servers Periods where we have insufficient capacity and our customers get a bad experience Actual Load TIME

IT CAPACITY TIME Load Forecast Actual Load Capacity on Demand Slide Objectives: Understand that Windows Azure allows capacity to be turned on and off easily Capacity can be brought on stream very quickly (no need to order servers in advance) Speaking Points: Lowers capex through not having to pay for hardware Reduces waste of ovefr capacity Ensures we can always provision enough capacity for peak periods Can reduce capacity if demand subsides Actual Load TIME

Cloud Services “IaaS” “PaaS” “SaaS” Host Build Consume Amazon Software-as-a-Service Consume GMail “SaaS” Platform-as-a-Service Build Microsoft “PaaS” Infrastructure-as-a-Service Host Amazon “IaaS” Slide Objectives: Explain the three established terms in the industry for cloud services Speaking Points: With this in mind, it’s important to understand how to talk about our Cloud Services offerings. There is a lot of confusion in the industry when it comes to the cloud. It’s important that you understand both what is happening in the industry and how we think about the cloud. This is the most commonly used taxonomy for differentiating between types of cloud services. The industry has defined three categories of services: IaaS – a set of infrastructure level capabilities such as an operating system, network connectivity, etc. that are delivered as pay for use services and can be used to host applications. PaaS – higher level sets of functionality that are delivered as consumable services for developers who are building applications. PaaS is about abstracting developers from the underlying infrastructure to enable applications to quickly be composed. SaaS – applications that are delivered using a service delivery model where organizations can simply consume and use the application. Typically an organization would pay for the use of the application or the application could be monetized through ad revenue. It is important to note that these 3 types of services may exist independently of one another or combined with one another. SaaS offerings needn’t be developed upon PaaS offerings although solutions built on PaaS offerings are often delivered as SaaS. PaaS offerings also needn’t expose IaaS and there’s more to PaaS than just running platforms on IaaS.

Speaking Points: Here’s another way to look at the cloud services taxonomy and how this taxonomy maps to the components in an IT infrastructure. Packaged Software With packaged software a customer would be responsible for managing the entire stack – ranging from the network connectivity to the applications. IaaS With Infrastructure as a Service, the lower levels of the stack are managed by a vendor. Some of these components can be provided by traditional hosters – in fact most of them have moved to having a virtualized offering. Very few actually provide an OS The customer is still responsible for managing the OS through the Applications. For the developer, an obvious benefit with IaaS is that it frees the developer from many concerns when provisioning physical or virtual machines. This was one of the earliest and primary use cases for Amazon Web Services Elastic Cloud Compute (EC2). Developers were able to readily provision virtual machines (AMIs) on EC2, develop and test solutions and, often, run the results ‘in production’. The only requirement was a credit card to pay for the services. PaaS With Platform as a Service, everything from the network connectivity through the runtime is provided and managed by the platform vendor. The Windows Azure Platform best fits in this category today. In fact because we don’t provide access to the underlying virtualization or operating system today, we’re often referred to as not providing IaaS. PaaS offerings further reduce the developer burden by additionally supporting the platform runtime and related application services. With PaaS, the developer can, almost immediately, begin creating the business logic for an application. Potentially, the increases in productivity are considerable and, because the hardware and operational aspects of the cloud platform are also managed by the cloud platform provider, applications can quickly be taken from an idea to reality very quickly. SaaS Finally, with SaaS, a vendor provides the application and abstracts you from all of the underlying components.

Windows Azure Platform PaaS

Windows Azure Platform Scalable compute and storage Automated service management Familiar tools, technologies, languages Relational storage for the cloud Consistent development model Automated database management Connect existing apps to the cloud Connect through network boundaries Easily control authorization to apps

Storage Options in Windows Azure Platform: Windows Azure Storage Instance: non-relational storage by means of services that use BLOBS Tables Queues (cheap, but have to programmatically handle Referential Integrity, Transactions, Performance, etc…) SQL Azure (more expensive that #1, but gives us relational storage with powerful and robust database engine we all know and love)

SQL Azure Database as a Service

History First introduced in Community Technology Preview (CTP) as SQL Server Data Services (SSDS) SSDS was non-relational (similar to current Windows Azure Storage instances) and was an altogether new approach to persisting data. Customers complained. They wanted: Relational engine Easy way to Migrate existing apps To use the skill set they already have. Exit SSDS. Enter SQL Azure. (Yay! A Database!)

SQL Azure Database The first and only true database as a service Subtitle color Managed Service Scale On Demand Innovate Faster Easy provisioning and deployment Auto high-availability and fault tolerance No need for server or VM administration Database utility; pay as you grow Business-ready SLAs Enable multi-tenant solutions World-wide presence Build cloud-based database solutions on consistent relational model Leverage existing skills through existing ecosystem of developer and management tools

SQL Azure Physical Architecture Apps Tools ODBC ADO.NET TDS SQL Azure Services Connection Routing Billing Provisioning Server Server Server SQL Server SQL Server SQL Server SQL Azure Fabric SQL Azure Fabric SQL Azure Fabric Infrastructure Database 1 Database 2 Database 3
