Microsoft Azure Infrastructure Services for Architects

By: John Savill

Overview of this book

With Microsoft Azure challenging Amazon Web Services (AWS) for market share, there has been no better time for IT professionals to broaden and expand their knowledge of Microsoft’s flagship virtualization and cloud computing service. Microsoft Azure Infrastructure Services for Architects: Designing Cloud Solutions helps readers develop the skills required to understand the capabilities of Microsoft Azure for Infrastructure Services and implement a public cloud to achieve full virtualization of data, both on and off premise. Microsoft Azure provides granular control in choosing core infrastructure components, enabling IT administrators to deploy new Windows Server and Linux virtual machines, adjust usage as requirements change, and scale to meet the infrastructure needs of their entire organization. This accurate, authoritative book covers topics including IaaS cost and options, customizing VM storage, enabling external connectivity to Azure virtual machines, extending Azure Active Directory, replicating and backing up to Azure, disaster recovery, and much more

Many customers will use the Azure IaaS services, which are fundamentally virtual machines. The reasons for having a domain on premises (central authentication, policy, directory services) likely still apply to the operating systems deployed in Azure IaaS, which means often the AD services from on premises need to be extended to Azure.

As mentioned at the start of this chapter, two things are required for Active Directory to be leveraged by computers, users, and services:

  • The ability to locate a domain controller or specific service, which for Active Directory means DNS name resolution for DNS servers hosting the domain DNS partitions
  • The ability to communicate with the located domain controller using a variety of protocols, such as Lightweight Directory Access Protocol (LDAP), Kerberos, RPC, or Netlogon
