What is cloud infrastructure? - Definition from

Cloud infrastructure refers to a virtual infrastructure that is delivered or accessed via a network or the internet.

This usually refers to the on-demand services or products being delivered through the model known as infrastructure as a service IaaSa basic delivery model of cloud computing. For example, the user can log in to cloud infrastructure and services IaaS platform to create virtual machines VMs ; install operating systems in each VM; deploy middleware, such as databases; create storage buckets for workloads and backups; and install the enterprise workload into that VM.

Customers can then use the provider's services to track costs, monitor performance, balance network traffic, troubleshoot application issues, manage disaster recovery and more.

Any cloud computing model requires the participation of a provider. The provider is often a third-party organization that specializes in selling Cloud infrastructure and services. A business might also opt to deploy a private cloudbecoming its own provider of infrastructure services. IaaS pros and cons Organizations choose IaaS because it is often easier, faster and more cost-efficient to operate a workload without having to buy, manage and support the underlying infrastructure.

With IaaS, a business can simply rent or lease that cloud infrastructure and services from another business. IaaS is an effective model for workloads that are temporary, experimental or that change unexpectedly. For example, if a business is developing a new software product, it might be more cost-effective to host and test the application using an IaaS provider.

Once the new software is tested and refined, the business can remove it from the IaaS environment for a more traditional, in-house deployment. Conversely, the business could commit that piece of software to a long-term IaaS deployment, where the costs of a long-term commitment may be less. In general, IaaS cloud infrastructure and services pay on a per use basis, typically by the hour, week or month.

Some IaaS providers also charge customers based on the amount of virtual machine space they use.


This pay-as-you-go model eliminates the capital expense of deploying in-house hardware and software. The disks in each system are aggregated using a distributed file system designed for a particular storage scenario, such as objectbig data or block. Decoupling the storage control and management from the physical implementation via a distributed file system simplifies scaling.

It also helps cloud providers match capacity to users' workloads by incrementally adding compute nodes with the requisite number and type of local disks, rather than in large amounts via a large storage chassis.

In a private cloudan organization typically owns the cloud infrastructure components and cloud infrastructure and services them within its own data center.

In a public cloud model, the cloud infrastructure components are owned by a third-party public cloud provider. A hybrid cloud consists of a mix of both models.

Cloud infrastructure

Cloud infrastructure as a service While cloud infrastructure is the hardware and software components required for cloud computing, infrastructure as a service IaaS is a cloud model that gives organizations the ability to rent those IT infrastructure components -- including compute, storage and networking -- over cloud infrastructure and services internet from a public cloud provider.

This public cloud service model is often referred to as IaaS.


IaaS eliminates the upfront capital costs associated with on-premises infrastructure, and instead follows a usage-based consumption model.
