Читать книгу Mastering Microsoft Azure Infrastructure Services - Savill John - Страница 7

Here is a glance at what's in each chapter.

Chapter 1: The Cloud and Microsoft Azure 101 provides an introduction to all types of cloud service and then dives into specifics about Microsoft's Azure-based offerings. After an overview of how Azure is acquired and used, Infrastructure as a Service (IaaS) is introduced with a focus on the difference between a best effort and a reliable service and why best effort may be better.

Chapter 2: When to Use IaaS: Cost and Options answers the first question posed by most organizations that have plenty of on-premises infrastructure: why would I use public cloud solutions? Key IaaS scenarios are explored to help you identify ways in which public cloud and IaaS solve problems that can't be easily replicated on-premises and how public cloud pricing can be compared to on-premises. The easiest way to understand the simplicity of IaaS is by creating a new VM and seeing the core options available. The sizes of virtual machines are explained and the cost and feature implications explored, including licensing of Windows and other applications such as SQL Server.

Chapter 3: Customizing VM Storage looks beyond creating a VM and explores customizing virtual machines with a focus on storage. Here you will learn about adding storage and the types of cache configuration, combining storage within virtual machines to make large volumes, how storage works and is replicated inside Azure and between datacenters, and more.

Chapter 4: Enabling External Connectivity explores offering services running from within Azure out to Internet-based consumers. Key concepts, such as endpoints for offering services and load-balanced services for greater service availability, are presented. Core Dynamic IP and Virtual IP concepts are introduced. You will see how they are used in Azure and under what circumstances they may change. The focus is on the difference between stopped and deprovisioned and the cost implications of those states. Local DNS will be explored, along with limitations for communication and name resolution between various cloud services in a subscription.

Chapter 5: Using Virtual Networks builds on the basic communication between VMs in a cloud service. Virtual networks provide a construct to enable customizable IP space configurations that are used by multiple cloud services, thus enabling cloud service-to-cloud service communication and on-premises communication. This chapter dives into architecting, configuring, and managing virtual networks and includes features such as reserving IP addresses for specific virtual machines via PowerShell. Availability sets and affinity groups are explained to help make multi-instance services as highly available as possible. Affinity groups form the foundation for virtual networks.

Chapter 6: Enabling On-Premises Connectivity builds on virtual networks and enables secure IP connectivity between services in Azure and those on-premises. This chapter starts by using site-to-site VPN gateway functionality, including basic configuration using software and hardware on-premises gateways, and then explores the point-to-site VPN options. The new ExpressRoute connectivity option is presented for organizations that do not want communication over the Internet and have connectivity and performance requirements that are not possible with the basic site-to-site VPN offering.

Chapter 7: Extending AD to Azure and Azure AD describes your next step once you've enabled IP connectivity between Azure and your on-premises infrastructure: joining VMs in Azure to the corporate Active Directory (AD). This can be done by accessing domain controllers on-premises once the appropriate DNS changes are configured in Azure virtual networks. Ultimately, you may want domain controllers in Azure, and this chapter looks at those options and best practices for offering your Active Directory in Azure. The Azure Active Directory is explained: how it compares to Active Directory Domain Services, how they can be connected, and some of the benefits of Azure Active Directory Premium.

Chapter 8: Setting Up Replication, Backup, and Disaster Recovery looks at a common scenario for using Azure for disaster recovery purposes. You should understand that this use case requires services and data to be replicated to Azure. This chapter looks at best practices and technologies for replicating various types of service, such as SQL Server, SharePoint, file services, and entire operating systems, to Azure. You will see what a failover would look like, and you'll learn about the possible implications. Using Azure as a backup target will also be explored, along with how to back up VMs running in Azure.

Chapter 9: Customizing Azure Templates and PowerShell Management dives into how to create your own Azure templates and key considerations that must be given focus if you want custom templates and existing VHDs to work in Azure. Capabilities for capturing existing Azure VMs and turning them into images are covered. PowerShell management is explored, along with the first steps to automation. The Azure VM Agent and its various capabilities are explained.

Chapter 10: Managing Hybrid Environments with System Center looks at architecting a hybrid environment. Here you will learn how to manage and monitor a true hybrid solution. The ability to move resources between on-premises and public cloud with custom code and with System Center is examined. How to perform bulk import and export operations for large-scale migrations is also covered. Advanced scenarios, such as a single provisioning service that automatically creates services on-premises or Azure based on the requirements of the VM request, are presented with a focus on a single experience for the end user.

Chapter 11: Completing Your Azure Environment dives into Azure services that, while not strictly Azure IaaS, provide benefits to a complete solution. You will be introduced to Azure Traffic Manager, Azure Web Sites, Azure Automation, Azure Scheduler, and more. Although IaaS is very powerful, the additional Azure capabilities covered in this chapter enable full-featured environments with the ultimate efficiency.

Chapter 12: What to Do Next brings everything together and looks at how to get started with Azure, how to plan your next steps, how to stay up-to-date in the rapidly changing world of Azure, and the importance of overall integration.
