Operations with VMware vSphere

Making sure your applications get what they need from their VMs

This event has ended.

What you’ll learn and how you can apply it

By the end of this live, hands-on, online course, you’ll understand:

  • Virtual machine hardware and how it affects applications inside the VM
  • What happens when VMs are snapshotted, cloned, or migrated

And you’ll be able to:

  • Assign the right resources to a VM to deliver application performance
  • Safely snapshot and clone virtual machines

This course is for you because…

  1. You are an operations engineer with Microsoft or Linux skills and you need to be able to configure the VMs running these operating system on an existing vSphere platform.

  2. You work in application support with deep knowledge of the applications that run the business and you need to understand and manage how the virtual machine configuration impacts your application.
