IaaS | Infrastucture-as-a-Service

A-to-Zerto Glossary of Terms



Unlike the traditional model of physical infrastructure, IaaS, or infrastructure as a service, uses the cloud to provide fundamental computing, networking, and storage resources over the internet. Typically relying on a subscription or pay-as-you-go model, IaaS enables organizations to scale resources up or down based on demand.  

What Is IaaS ?

IaaS has quickly become the standard model for many types of workloads, supplying essential computing infrastructure over the internet. IaaS includes both physical and virtualized resources that provide what’s needed to run your applications and workloads in the cloud. 

IaaS providers manage large datacenters, typically around the world, that contain the physical machines required to power the various layers of virtualized computing resources on top of them. These offerings typically come with supportive services like auto-scaling and load balancing. IaaS also includes networking and storage services.

Why Choose IaaS?

The popularity of IaaS is largely due to its flexibility and its cost-effectiveness. IaaS is flexible because it allows you to easily scale your computing infrastructure up or down depending on the needs and requirements of your organization. It also gives you the flexibility to choose a disaster recovery solution from a third party. Its cost-effectiveness comes from both the pay-as-you-go model and the reduction of expenditures for physical components or other private infrastructure.

Zerto and IaaS

Utilizing Zerto with a cloud infrastructure such as IaaS can be an immensely powerful mechanism for achieving best-in-breed RPO and RTO without the costly need for a whole secondary infrastructure dedicated to disaster recovery. With Zerto, you pay the low cost of storage most of the time and only incur costly IaaS compute when a failover is triggered; this brings vast savings and greatly reduces the TCO to achieve the fastest RPO and RTO for your disaster recovery strategy.
