IntroductionCloud computing is reality now, defining how IT is handled not only in large, medium, andsmall enterprises but also in—consumer—facing businesses. The cloud itself is a familiarcliché, but when you attach computing, it brings with it a slew of services, vendors, and such,and the horizon includes virtual server providers, hosting providers, virtual storage and networking providers, hypervisor vendors, and private/public cloud providers.The enterprise IT landscape has always been well-defined and segmented. Cloud computing initially started with replacing the traditional IT model; any business that had anything to do with computers and software (and that was almost 100 percent of businessesaround the world) would need to acquire physical servers (often racks of them, dependingon the size of the business) and storage and networking components. The business thenhad to construct a specially designed data center to deploy the components then configure,support, and manage the data center. Specialized IT skills were needed for executing adata center and managing it. Only large-scale enterprises and well-funded businesses couldafford to undertake this. Even for large enterprises that had their own massive data centersfor distributing enterprise applications to the workers and storing business data, operatingthe data center itself was a distraction that added to costs.Cloud computing is a natural transition from this legacy model of enterprise IT to aworld where computing can be sold and purchased just like any other commodity, whereconsumers would pay only for what they use, without steep up-front bills. You can now“order” 100 virtual servers and build enough computing capacity to run an applicationconsumed by 100 million users over the Internet without owning a single server or writinga huge check to cover up-front costs. The cloud has not only ushered in a new age for enterprise IT, it has become the enabler technology for the Internet startups of today. It wouldbe safe to say that a lot of very well-known Internet businesses wouldn’t be possible if therewere no cloud.Who Should Read This BookThe global cloud market is expected to reach 270 billion by 2020. With most governmentand corporate IT moving into the cloud, this is the perfect time to equip yourself with theright skills to thrive in cloud computing.Even though cloud computing has significantly lowered the barrier for businesses to useIT resources on demand, this does not mean that you can create your company’s virtualdata center in the cloud with just a few clicks. Building the right cloud infrastructure andefficiently managing and supporting it requires specialized skills. In addition to cloud practitioners, this book is for IT students who want to take a dive into understanding the conceptsbehind some of the key technologies that power modern cloud solutions and are essential fordeploying, configuring, and managing private, public, and hybrid cloud environments.Additionally, the topics covered in this book have been selected to address the CompTIACloud certification CV0-001, as indicated in the title of the book.
xxivIntroductionIf you’re preparing for the CompTIA Cloud certification CV0-001, this book is idealfor you. You can find more information about the CompTIA Cloud certification /certifications/cloudplus.aspxHow This Book is OrganizedThe topics in this book were chosen to cover a wide range of cloud technologies, deployment scenarios, and configuration issues as well as fundamental concepts that define moderncloud computing. Every chapter begins with an introduction and a list of the topics coveredwithin it. To enhance your learning experience, we’ve included hands-on exercises and realworld scenarios. The book also includes a practice exam that covers the topics presented ineach chapter, which will help you prepare well for the certification exam.Chapter 1, “Understanding Cloud Characteristics,” starts off with a detailed overview ofthe key terms related to cloud computing, including discussions of elasticity, metering/billingwith the pay-as-you-grow model, network access, multitenancy, and a hybrid cloud scenariowith cloud bursting, rapid deployment, and automation. The chapter also covers key conceptsin object-based storage systems, including object IDs, metadata, access policies, and enablingaccess through REST APIs.Chapter 2, “To Grasp the Cloud—Fundamental Concepts,” takes a dive into the key pieceof technology that makes it possible to enable cloud computing—virtualization. This chaptercovers Type 1 and Type 2 hypervisors and their differences plus popular open-source and proprietary hypervisors that are available today with an overview of their key features. It also covers consumer versus enterprise use cases and workstation versus infrastructure virtualization.We discuss the key benefits of virtualization, like shared resources, elasticity, and completeresource pooling, including compute, storage, and network. The chapter ends with a discussion of the fundamentals of cloud computing in the context of virtualization technology.Chapter 3, “Within the Cloud: Technical Concepts of Cloud Computing,” takes a diveinto the technical aspects of scalable computing, which include a comparison of traditionaland cloud infrastructures, selecting the right infrastructure for building your own cloud,scaling and optimizing a data center, and economies of scale. At the end of the chapter,there’s a section on cloud infrastructure, which covers open-source and proprietary solutions and includes a discussion on choosing between creating in-house tools or selectingthird-party solutions and what drives the build versus buy decisions when it comes tocloud infrastructure.Chapter 4, “Cloud Management,” includes a plethora of scenarios, use cases, and issuesassociated with managing deployment and ongoing support for your cloud implementation.Broadly, this includes managing your own cloud, managing workloads in the cloud, andmanaging business data assets that live in the cloud, including data migration and securestorage and access of the data. The cloud is device agnostic, so controlling and managingaccess to the cloud by a plethora of devices—a concept known as BYOD—is also discussed.
IntroductionxxvChapter 5, “Diagnosis and Performance Monitoring,” discusses the aspects of a cloudimplementation that you’ll want to gauge and monitor. This includes performance metricsacross compute (e.g., IOPS and load balancing), network (e.g., latency and bandwidth), andstorage (e.g., file system performance and caching) resources. We also discuss best practicesto achieve optimal performance with the hypervisor and common failure scenarios.Chapter 6, “Cloud Delivery and Hosting Models,” dives into the three main types of cloudsin terms of delivery and access: public, private, and hybrid. On-premise and off-premise hosting options are discussed for all three types. At the end of the chapter is a discussion of thesecurity and functionality aspects of these models.Chapter 7, “Practical Cloud Knowledge: Install, Configure, and Manage,” provideshands-on practical knowledge of the intricacies of setting up and managing your owncloud infrastructure. The chapter includes key discussions on creating a complete virtualized data center and configuring virtual compute, storage, and networking components.We’ll discuss migrating existing data and compute workloads to a newly built cloud andprovide an overview of the key virtual components of the cloud.Chapter 8, “Hardware Management,” walks through the physical hardware componentsthat make up a cloud. Pros and cons of hardware design choices are discussed, including compute (e.g., number of cores and parallelism), storage (e.g., magnetic/spinning disk versus SSD),and networking (e.g., NIC quantities, types, and speed). Toward the end of the chapter, there’san in-depth discussion of cloud storage options.Chapter 9, “Storage Provisioning and Networking,” dives deep into creating virtualizedstorage, managing storage security and access, and provisioning models. We’ll show youhow to configure networking for the cloud, including how to create and configure multiplevir
