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

If they deploy two VMs and remember to use availability sets or availability zones, they have HA but still don’t have DR. They may learn this fact in a very painful way if there is a rare region-level incident and their service goes dark and a lot of uncomfortable discussions commence.

This is important to understand, and it applies to both IaaS and PaaS. Your deployments are to a region. Very rarely, even for PaaS, are deployments across regions. This does not mean there are not technologies to help deploy to multiple regions, to balance between them, or to set...
