The availability of Azure VMs
When working with VMs, you’ll face various scenarios:
- Deploying a single machine
- Deploying multiple machines as separate hosts
- Deploying multiple machines as connected hosts
Depending on your scenario, different approaches will be needed to achieve what you need. For example, up until now, we deployed multiple VMs, which were mostly unrelated hosts. This is the simplest scenario from a deployment point of view, but gives us no real resiliency. It’s time to learn how to achieve HA in Microsoft Azure when deploying IaaS components. Learning about that topic will help in real-world scenarios, which very often require improved availability of your infrastructure due to business requirements.
Availability sets
Each deployed VM in Azure has specific hardware powering its capabilities. In other words, anytime you deploy something in Azure, the data center will select the proper placement for it in terms of physical location...
