Cloud computing, as its name suggests, is to leverage cloud for computing workloads. These workloads are not new—we have been running applications and services on our workstations and data centers for tens of years. Then why do we need cloud? What benefits are we getting by using it? What are the new scenarios it enables? In this first section of the book, we first look back at the history of cloud computing, and then discuss some unique and exciting capabilities cloud computing brings us. We also study the basics of getting your workloads on cloud using Microsoft developer tools and services. From a developer’s perspective, you can view cloud as a huge resource pool where you can pull out resources to support your application needs, and return the resources when you are done with them. This resource usage model is the foundation of key cloud characteristics such as elasticity, availability, and agility.

developers to programmatically access most of the Microsoft Azure Management Portal capabilities Microsoft Azure Management API is a RESTstyled API, and requires SSL and certificated-based authentication to ensure security Now let us learn programming with Microsoft Azure Management API with a simple example Example 17.2: Use Microsoft Azure Management API Difficulty: *** First, acquire a certificate We can use the makecert tool to generate a self-signed certificate: makecert -r -pe -a sha1 -n "CN=My Azure Management Certificate" -ss My -len 2048 -sp "Microsoft Enhanced RSA and AES Cryptographic Provider" -sy 24 myazuremanagementcert.cer Once the certificate is generated, we need to use Microsoft Azure Management Portal to upload this certificate Sign in to Microsoft Azure Management Portal In the navigation pane, click the SETTINGS link On the settings view, click the UPLOAD button on the command bar Pick the certificate you just created, and select the subscription to use (if you only have one subscription, you don’t see the subscription field) Click the check button to continue Then, you need to get the subscription ID When you invoke Microsoft Azure Management API calls, you need to provide the subscription ID to uniquely identify your Microsoft Azure subscription You can use the following Microsoft Azure PowerShell cmdlet to get the name, ID, and certificate of a subscription: Get-AzureSubscription | Format-Table @{Expression= {$_.SubscriptionName};width=25}, @{Expression= {$_.SubscriptionId};width=40}, @{Expression = {$_.Certificate Thumbprint}} Figure 17.6 is an example of the result of executing this command Create a new Windows Console application Modify the Program.cs file to enter the source code as shown in Code List 17.1

So it is not surprising to see developers becoming superheroes, who take care of everything This phenomenon is often observed in start-ups, who have been major advocators and beneficiaries of the movement For larger enterprises and interdependent software vendors (ISVs), it is unrealistic to expect such complete fusion Instead, operations personnel behave more and more like developers as they start to work with abstract artifacts, codes, and scripts Although, in many larger enterprises, the work style and human resource allocations have been fixed by existing architectures and legacy systems However, this does not mean these companies cannot adopt DevOps for their new projects at a smaller scale 18.1.3 Every Day Is Release Day The landscape of marketing has drastically changed over the past decade Consumers are more proactive than ever Nowadays, people use technology at their fingertips to search for products and services instead of waiting to hear something they might like in marketing campaigns For a service provider, getting a higher rank in search engines and a better rating in popular sites are becoming far more important than marketing campaigns And once they get a customer, they also need to take measures to retain that customer, as the customer is in a position to find the next big thing at any time Continuous engagement with customers has become key to sustainable business And with development and operations folding into one unit, products can be released more frequently, changes can be applied quickly, and new features can be introduced more promptly Such unprecedented agility provides ISVs opportunities to respond to market changes faster and to maintain relationships with their customers Azure and DevOps ◾ 483 18.2 VM Agent and VM Extensions Configuration automation is a fundamental requirement of DevOps Microsoft Azure provides both first-party and third-party options to capture and automate machine configurations at scale And all of this is possible because of VM Agent, which we discuss next 18.2.1 VM Agent VM Agent is a lightweight process that can pull down additional VM Extensions, which are software packages that can be dynamically installed in your virtual machines to customize them to meet your specific project needs When you create a new virtual machine using Azure Management Portal, the VM Agent is enabled by default, as shown in Figure 18.1 If you want to install VM Agent to an older virtual machine, which does not come with a built-in VM Agent, you can download and run the Agent installer from this link: http://go.microsoft.com/fwlink/? LinkID=394789&clcid=0x409 18.2.2 VM Extensions Once VM Agent is installed on a virtual machine, it can acquire and install additional VM Extensions from the Azure VM Extension Gallery, as shown in Figure 18.2 At the time of writing, there are only a limited number of VM Extensions available from the VM Extension Gallery You can use PowerShell cmdlet Get-AzureWMAvailableExtension Figure 18.1 VM Agent is enabled by default 484 ◾ Zen of Cloud Azure VM Azure VM agent Extension Extension package Azure VM extension gallery Figure 18.2 Install VM Extensions from Gallery Figure 18.3 List of available VM Extensions Figure 18.4 List of Extensions installed on a VM (requires Microsoft Azure PowerShell; see Chapter 17) to list currently available extensions, as shown in Figure 18.3 If you want to list extensions that are already installed on a VM, you can use the GetAzureVMExtension command, as shown in the example in Figure 18.4 18.2.3 Custom Script Extension Custom Script Extension is a VM Extension that can automatically download and execute PowerShell scripts and files from Azure Storage Although the functionality of this agent is very simple, it can help you accomplish lots of customization scenarios because of the capability of PowerShell To install the Custom Script Extension, you can use cmdlet Set-AzureVMExtension, as shown in Figure 18.5 Azure and DevOps ◾ 485 Figure 18.5 Install Custom Script Extension Once the Custom Script Extension has been installed, you can start to pull down additional PowerShell scripts from your Azure Storage account and execute them In this case, I have uploaded a simple PowerShell script that simply prints “Hello World” to the output stream: Host-Write "Hello World!" Assume the script has been uploaded to my BLOB container powershell under my haishigateway account, then I can use Set-AzureVMCustomScriptExtension command to launch the script and update my virtual machine: Set-AzureVMCustomScriptExtension -ContainerName powershell -StorageAccountName haishigateway -FileName HelloWorld.ps1 -VM $vm -ReferenceName 'CustomScriptExtension' | Update-AzureVM -Verbose The output of this command is shown in Figure 18.6 To get the execution result, which can be written to either Stdout stream and/or StdErr stream, you need to refresh your virtual machine reference and then read the script execution result from its ResourceExtensionStatusList.ExtensionSettingStatus.SubStatusList property, as shown in Figure 18.7 18.2.4 DSC, Puppet, and Chef Desired state configuration (DSC), Puppet, and Chef are all configuration automation systems They allow you to choose desired states for your resources, and they make sure your requirements are met With these systems, configurations are centralized, and configuration updates are either pushed from a server or periodically pulled by agents installed on target machines Figure 18.6 Output of custom script run Figure 18.7 Retrieve script execution results 486 ◾ Zen of Cloud You may have noticed that both Puppet Agent and Chef Client are provided as VM Extensions (see Figure 18.1) DSC is part of PowerShell 4, and your configurations can be applied via mechanisms such as the Custom Script Extension we introduced in the previous section As we have discussed at the beginning of this chapter, being able to capture and automatically reinforce infrastructural requirements across different environments is one of the key enabling technologies for DevOps Unfortunately, we cannot cover these systems here as each deserves an entire book Interested readers can visit the author’s blog (http://blog.haishibai.com) to find several tutorials on these technologies 18.3 New Portal Early in 2014, a new Microsoft Portal was put into preview Existing Azure subscribers can visit https://portal.azure.com/microsoft.onmicrosoft.com to access the new portal (Figure 18.8) The new portal looks fairly different from the current portal The current portal design is resource oriented, where you can provision, manage, and monitor your Azure resources with ease The new portal focuses on your applications instead of scattered resources When you deploy an application to cloud, you probably need to provision a bunch of related resources, such as a web server, an application server, and a database In the current portal, you cannot really treat them as a single unit However, the new portal supports the concept of Resource Groups, which allow you to manage a group of related cloud resources as a single unit Figure 18.8 Microsoft Azure Preview Portal Azure and DevOps ◾ 487 Figure 18.9 A Journey on Azure portal The new portal is also highly customizable You can manage your home page tiles just as you can on a Windows PC or Windows phone You can pin everything related to your application on the home page so that you can have a consolidated view of your application Another concept of the new portal is Journey When you perform operations, the screen keeps expanding to the right, guiding you through multistep operations and revealing more and more relevant information (see Figure 18.9) And as you complete operations, you are brought back toward the left till you return to the home page A Journey is saved across browser sessions So the next time you log in, or open the portal from a different machine, you can pick up from where you left off The new portal provides strong support for DevOps It is fully integrated with Visual Studio Online, Azure monitoring, billing, and various other services so that you can gain incredible insights into every aspect of your application The dynamic UI may seem a little intimidating at the beginning, but once you have tried out a couple of operations, you will find out that the new portal is really easy to use and can become a vital tool for your DevOps scenarios 18.4 Zen of Cloud The core concept of cloud is to separate business applications from underlying infrastructures The value of cloud resides in reduced operation cost, improved quality of service, and unprecedented agility The opportunity brought by cloud is the innovations that can happen once applications are freed from the constraints of infrastructures Finally, the future of cloud is Ubiquitous Cloud promoting Ubiquitous Computing to the next level, where the real world and the cyber world merge into one No matter how technology evolves, at the end, people want the required functionalities to be delivered and to remain accessible The separation of applications and infrastructure allows application and service developers to better focus on developing core business values, without having to worry about how to tailor the application for particular platforms It is foreseeable that in the near future, local data centers, or even single server boxes, will adopt the same infrastructure designs as those for cloud platforms The parity between cloud, local systems, and even mobile systems unifies the application ecosystem so that an application can be written once and be made available everywhere An application or a service can be migrated freely among on-premises datacenters, private clouds, community clouds, and public clouds Choosing a hosting environment will no longer be an architectural decision, but just an operational decision For many software developers, the key for adopting cloud is the shift in mindset from scaling out to scaling up, from controlled environment to dynamically composed environment, and from 488 ◾ Zen of Cloud single-instance reliability to collective reliability None of these concepts are new Actually, experienced large-scale system designers and developers have been doing these things for years It is just that they are getting the public’s long-overdue attention now The real revolutionary changes brought by cloud reside in the area of Big Data and Internet of Things (IoT) Both Big Data and IoT need the capability of large scale, highly available data acquisition, transmission, storage, and manipulation Cloud provides all of these It infuses new, potent, infinite energy into Big Data and IoT development, making them both thrive on cloud Cloud is still young, and the developments in the field have been phenomenal We hope this book provides some practical help along your cloud journey, and we wish you great success with your cloud projects Thank you! uploaded by [stormrg] Bibliography Bertocci, V Programming Windows Identity Foundation Redmond, WA: Microsoft Press, 2011 Brown, J W Anti
