Overview of this book

vSphere 6.7 is the latest release of VMware's industry-leading virtual cloud platform. By understanding how to manage, secure, and scale apps with vSphere 6.7, you can easily run even the most demanding of workloads. This Learning Path begins with an overview of the features of the vSphere 6.7 suite. You'll learn how to plan and design a virtual infrastructure. You'll also gain insights into best practices to efficiently configure, manage, and secure apps. Next, you'll pick up on how to enhance your infrastructure with high-performance storage access, such as remote direct memory access (RDMA) and Persistent memory. The book will even guide you in securing your network with security features, such as encrypted vMotion and VM-level encryption. Finally, by learning how to apply Proactive High Availability and Predictive Distributed Resource Scheduler (DRS), you'll be able to achieve enhanced computing, storage, network, and management capabilities for your virtual data center.

Right-sizing virtual machines

Right-sizing a virtual machine means allocating the correct amount of CPU, memory, and storage resources that are required to support a virtual machine's workload. The optimal performance of the virtual machine and the efficient use of the underlying hardware are both obtained through right-sizing virtual machine resources.

In a physical server environment, it can be difficult and time-consuming to add resources:

  1. Compatible parts will need to be identified
  2. The parts will need to be ordered
  3. You will likely need to wait weeks for the parts to arrive
  4. Someone will need to be in the data center
  5. The server will need to be shut down
  6. The server will need to be removed from the rack and opened up
  7. The parts need to be installed

Because of this, physical servers are often configured with more resources than are actually required to ensure that there...
