For most of us idle wanderers of the interwebs, it’s easy to imagine that all the websites and applications we come across in our net travels exist in some invisible realm watched over by armies of tech wizards. Of course, in reality all the information that gets channeled to our devices has to be stored in some physical location, and for applications to work data has to be processed by an actual machine somewhere. APTERAINC.COM |PG. 3 ????? Microsoft Azure WHAT IS MICROSOFT AZURE? Until recently, most of the computing people did relied on their device’s own hardware. Next, we started pulling information from other machines so we could view various types of web content. Then those websites began performing more and more tasks for us, so we were efectively using distant machines to do our computing and simply using our own devices as portals to the resulting output. APTERAINC.COM |PG. 4 Microsoft Azure WHAT IS MICROSOFT AZURE? Ofcial Defnition: “Azure is an open and fexible cloud platform that enables you to quickly build, deploy and manage applications across a global network of Microsoft-managed datacenters. You can build applications using any language, tool or framework. And you can integrate your public cloud applications with your existing IT environment.” APTERAINC.COM |PG. 5 Microsoft Azure WHAT IS MICROSOFT AZURE? With the rapid expansion of the market for mobile devices and businesses’ increasing reliance on ever-larger volumes of data, the idea of outsourcing your storage, processing, and hosting functions to third-party companies developed into what today we call the cloud. Azure is Microsoft’s general-purpose name for their cloud oferings in these domains. APTERAINC.COM |PG. 6 FACT: 57% of Fortune 500 companies are using Azure Microsoft Azure WHAT IS AZURE USED FOR? Cloud Services: Azure can be used as a platform for building and deploying applications. Your developers create the code with tools provided by Azure, and then virtual machines execute the application using Windows Server. Since the development and hosting tools are purchased through a subscription, Azure Cloud Services is an example of what’s called Platform as a Service (PaaS). APTERAINC.COM |PG. 7 <azure/> Microsoft Azure WHAT IS AZURE USED FOR? Cloud Services (cont’d): Your application will run on virtual machines, but unlike with the Virtual Machines services, Azure will install the operating system and continuously update it with any new patches. You can use Cloud Services to create diferent roles for users—web users and workers—and it’s really easy, as it is with all Azure tools, to scale up or down to accommodate more or fewer users. So you only ever pay for the computing power that actually gets used. APTERAINC.COM |PG. 8 ACTIVE USERS INACTIVE Microsoft Azure WHAT IS AZURE USED FOR? Virtual Machines: Azure gives you the ability to create VMs simply by specifying the size and the Virtual Hard Disk (VHD) you want to use. The VHD is the virtual version of a hard drive on a conventional computer; it’s where all the fles and applications are saved. Azure provides access to both Windows and Linux VHDs, so developers have the freedom to choose what they want to work with. You pay according to how much time the VM is actually running. Developers can use VMs to build and test applications quickly at low cost. APTERAINC.COM |PG. 9 VHD >$ Microsoft Azure WHAT IS AZURE USED FOR? Virtual Machines (cont’d): You can also use VMs to augment on-site datacenters to boost the power of applications like SharePoint. Since Azure Virtual Machines essentially gives you the computing substrate for your applications through a service subscription, it falls into the category of Infrastructure as a Service (IaaS). APTERAINC.COM |PG. 10 VHD Microsoft Azure WHAT IS AZURE USED FOR? Web Sites: You can use Azure as a platform for creating and hosting websites and web applications. Web Sites supports several diferent development tools and content management systems. And it provides a low cost way to make your site available to however many visitors use it without having to maintain or upgrade any on-site servers. APTERAINC.COM |PG. 11 www.aptera.com VHD Fact: >250,000 active websites on Azure Microsoft Azure WHAT IS AZURE USED FOR? Mobile Services: Like Cloud Services, Azure’s Mobile Services give you the tools to create and deploy applications, but obviously in this case the apps are used on mobile devices. The information that gets accessed by the app running on your device is stored in what’s called a back-end database, and so Mobile Services is referred to as mobile Back-end as a Service (mBaaS). With Azure, you can build apps for Android, iOS, HTML/ JavaScript, and Windows Phone. APTERAINC.COM |PG. 12 Fact: >1 million SQL Databases in Azure Microsoft Azure WHY DO BUSINESSES WANT TO USE SOMEONE ELSE’S HARDWARE? You get three basic advantages from using cloud platforms and infrastructure as opposed to on-site machines. 1. Speed Purchasing new servers, confguring them, and integrating them into your existing environment tends to be both costly and time-consuming. With Azure, you can set up an application and start building it out in minutes. APTERAINC.COM |PG. 13 $ $ $ $ $ $ $ $ $ $ $ Microsoft Azure WHY DO BUSINESSES WANT TO USE SOMEONE ELSE’S HARDWARE? 2. Scale Demand for your applications may be variable throughout the year (think tax return fling software). Or you may expect a low number of users at frst followed by huge growth as your application catches on. You may even expect usage to the decline, maybe because you’re launching another application. Scaling up with your own on-site servers means purchasing and provisioning them to accommodate growth. And once the servers are in place you still have to maintain them even if they’re not being used. APTERAINC.COM |PG. 14 VHD MO. USAGE JAN. FEB. MAR. APR. MAY JUNE JULY AUG. SEPT. OCT. NOV.

Economics If you’re expecting your application to start slow and then gain momentum—and who doesn’t want this to happen?—then you will probably start of with more processing capacity than you actually use. And if usage declines after a peak you’ll have a similar problem. With Azure, you only pay for what you use. On-site server farms also require a lot of maintenance: climate control, electricity, disaster recovery, backups, security. Moving to the cloud means freeing up your IT staf so they can focus on new projects instead of routine maintenance. APTERAINC.COM |PG. 15 VHD ON-SITE Microsoft Azure WHAT ARE THE ADVANTAGES OF VIRTUALIZATION? You can make use of virtualization in your on-site datacenters, but if you’re using Azure you’ll defnitely be relying on virtual machines to one extent or another. To create virtual servers on physical servers, you use software that sets up divisions between each virtual machine (VM) and allows them all to operate independently. What this does is add a layer of abstraction between your information and the physical infrastructure that hosts it. This in turn gives you more fexibility in how you manage and protect the various elements of your computing environment. The main advantages of virtualization come in four basic areas: APTERAINC.COM |PG. 16 VHD Microsoft Azure WHAT ARE THE ADVANTAGES OF VIRTUALIZATION? 1. Efciency Some applications may require relatively little processing power to run. By virtualizing your servers, you make it possible to devote an entire VM to each application. And by hosting multiple smaller servers on one large physical server you can signifcantly reduce overall energy costs. The VMs aren’t restricted to their physical servers either. So if you need more power to run them it’s really easy to pull in other machines to host them. APTERAINC.COM |PG. 17 VHD Microsoft Azure WHAT ARE THE ADVANTAGES OF VIRTUALIZATION? 2. Resilience With Azure, each of your VMs is ready to go on more than one actual machine. That means built-in redundancy if something goes wrong with an application. If your VM picks up a virus or some malware, it can simply be shut down without disrupting the operation of your application. And of course there’s also the assurance that if some type of natural disaster occurs the datacenter running your applications is secure—even if an entire Microsoft datacenter goes down there are still extra layers of redundancy. APTERAINC.COM |PG. 18 VHD Microsoft Azure WHAT ARE THE ADVANTAGES OF VIRTUALIZATION? 3. Testing It’s much easier to set up a VM than it is to purchase and provision a physical server. And you can never be sure running a new application won’t somehow afect existing applications running on the same machine. So developers uploads/Industriel/ azure-guide.pdf
