Virtualization: All You Need To Know | Zerto


A-to-Zerto Glossary of Terms



Virtualization refers to using software to enhance hardware functionality and create a computer system made of virtual machines (VMs). Because multiple operating systems, applications, and VMs can fit on a single server, the benefits of virtualization include greater efficiency and cost-effective scalability.  

What Is Virtualization?

Virtualization uses software to set up a layer on top of computing hardware that lets the hardware elements of a single computer—such as processors, memory, and storage—become shared resources. Each self-contained VM is completely independent, even running its own operating system.

Putting multiple VMs on a single computer enables several operating systems and applications to run on just one physical server, also known as a host. A thin layer of software called a hypervisor separates the VMs from the host and distributes the computing resources to each VM as needed.

Why Choose Virtualization?

To keep pace with today’s high storage and processing demands, most organizations must deploy multiple servers, each operating at a fraction of their capacity. This inefficient method results in high operating costs.

Virtualization enables greater and more effective use of your physical computer hardware which, in turn, generates a much bigger return on your organization’s hardware investment. Virtualization also supports cloud computing: it allows you to leverage your existing physical hardware and to purchase only the computing resources you need. In this way, your organization can scale computing resources cost-effectively as your needs grow.

Why Zerto for Virtualization?

Zerto is purpose-built for disaster recovery, backup, and data mobility for virtualized environments. Zerto specializes in virtualized environments and can offer the fastest RPO and RTO in the industry based on its best-in-class, hypervisor-based replication engine and its scalable, software-only solution. Only Zerto can provide continuous data protection for all use cases. Whether you need to recover a whole site or just a single file, Zerto can restore it within minutes to its exact state from a few seconds before the outage or corruption. 

Zerto can deliver all the benefits of virtualization: 

  • Increased IT agility and flexibility
  • Easy scalability
  • Significant cost savings
  • Greater workload mobility
  • Increased performance and availability of resources

The Zerto Virtual Manager (ZVM) sends protected site data once every minute, allowing you to monitor protection in real time, and the Zerto Resource Planner even lets you model your journal history requirements, giving you accurate data on demand.
