Software Challenges Today # of users? After 1 month? 6 months? 1 yr? Capacity? Servers? Bandwidth? Storage? How do you scale up or down over time? How can you handle peak loads? How do you provide high availability? What are the upfront capital costs? How quickly can you go live? How do you reduce your operations costs? Slide objectives: Provide some context for why there is hype/interest in the cloud by focusing on some of the practical issues developers face when building web applications. Speaking Points: Today there are a number of challenges that you face when building web applications. For example, imagine you are building what you hope will be the next big social networking site or online game. Or perhaps you are building a commerce site for selling tickets to sporting events. One of the first things you have to try to guestimate is the number of users. How many people do you expect to use your web application or service? After 1 month? After 6 months? Or after a year? Do you expect that the number of users will continue to scale up? How do users translate into capacity? Into servers? Or storage requirements? How do you scale up or down your web application over time? If you consider the online gaming scenario, you can imagine that when a new game is launched there is a spike in traffic and usage, but overtime the usage slows. How can you handle peak loads? For example, if you are selling tickets for a major sporting event and the tickets go on sale at a specific time – how do you ensure that you can scale to thousands of concurrent users? How do you provide high availability – not just during the peak loads, but how do you ensure a quick response time for all of your worldwide users? What are the upfront capital costs to build out the infrastructure? How quickly will the infrastructure be available? Or if you have an established application, how can you reduce your operations costs? Most of these challenges have little to do with which programming languages, tools, or application frameworks you are using. These are some of the problems that we believe the cloud can help address.

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.
