Infrastructure AS A Service (IaaS)

Infrastructure as a Service (IaaS) is a cloud computing service where enterprises rent or lease servers for compute and storage in the cloud. Users can run any operating system or applications on the rented servers without the maintenance and operating costs of those servers. Other advantages of Infrastructure as a Service include giving customers access to servers in geographic locations close to their end users. IaaS automatically scales, both up and down, depending on demand and provides guaranteed service-level agreement (SLA) both in terms of uptime and performance. It eliminates the need to manually provision and manage physical servers in data centers.

What are the Benefits of Infrastructure-as-a-Service?

Infrastructure as a Service (IaaS) can be more efficient for an enterprise than owning and managing its own infrastructure. New applications can be tested with an IaaS provider instead of acquiring the infrastructure for the test.

Other advantages of infrastructure-as-a-service include:

Continuity and disaster recovery

Faster scaling

Core focus

How to Implement Infrastructure as a Service?

The implementation can be in a public, private or hybrid cloud setting. Customers use a graphical interface to change the infrastructure as needed. The infrastructure can also be accessed through an API key — so new servers are brought online as part of an automation when needed.

Enterprises use IaaS to do the following more efficiently:

Test and development

Backup and recovery

Big data analysis

How Does Infrastructure as a Service Work?

IaaS started in the cloud as one of the service layers including Platform as a Service (PaaS) and Software as a Service (SaaS). Customers use dashboards and APIs to directly access their servers and storage. With IaaS, there is higher scalability.

IaaS users enjoy many advantages of Infrastructure as a service, such as accessing the same infrastructure technology services of a traditional data center without having to invest as many resources. It is a flexible cloud computing model that allows for automated deployment of servers, processing power, storage and networking.
