  • I’m here to share my vision with you about the future of IT and really of Ireland itself.
  • are those that look at the cloud as a lemming type buzz word drinking game.
  • To build an application or solution in a legacy world, you have to think about network, OS, storage, and scale. But they have little to do with what you really want to build, an application.But what if there were a different way.
  • Slide Objectives:Explain the three established terms in the industry for cloud servicesSpeaking 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.
  • Slide Objectives:Explain the differences and relationship between IaaS, PaaS, and SaaS in more detail.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 SoftwareWith packaged software a customer would be responsible for managing the entire stack – ranging from the network connectivity to the applications. IaaSWith 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 OSThe 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.PaaSWith 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.SaaSFinally, with SaaS, a vendor provides the application and abstracts you from all of the underlying components.
  •’s start with a quick discussion about where we’re at right now. Lots to add here…
  • There’s two reasons to move to the cloud – improve ROI on things that you were going to do anyway or improve your strategy and thereby lowering barriers to innovation.
  • second reason is to improve your strategy.
  • You could probably leave that as a question mark. Everyone knows it’s expensive to leave servers in a room running and shutting them down is waving good by to cash.
  • Depending on your presentation style I’d consider teeing the crowd up here. The last bullet point leaves the crowd in mystery.
  • You could say 80,000 would be a 40% saving on the original cost.
  • A 25% saving on the original cost?
  • 1/200th of the original cost? No way.
  • This is not a joke. Moving to Microsoft Azure reduced the cost of running the test to practically nothing. (A good quip here would be to say that $500 wouldn’t even cover the power strips needed to keep the servers running)
  • This is a deliberately bad chart, in that Azure can’t be seen. That will help hammer the point home that if you’re not using cloud, you’re basically not at the races.
  •’s a real issue that we are not setting out targets correctly. And we need to be aiming high enough and big enough to make a difference…
  • what’s the path to the cloud?
  • are three things that I want to talk about… Demand SideSupply SideInfrastructure
  • part of it starts with the education system and there is a tremendous amount of knowledge to assume. But we also need to upskill our current workforce.
  • we can’t connect to our users, then the strategy is a non-starter…Ensuring the continued investment in broadband and international internet connectivity to ensure sufficient capacity exists to support the growth of the Cloud industry
  • that I’ve shared my vision with you, I want for you to
  • Before I finish, I need to say a quick thank you to Fritz Ahlefeldt. He’s a Danish artist with obvious talent. He publishes a large amount of his work under creative commons. If you like this art, you can see much more at and support him and his amazing craft.
