An Overview of Infrastructure as a Service (IaaS)

The IT Universe Writers

Infrastructure as a service is a cloud computing technology. IaaS is one of the three components of cloud computing services. The other two services are platform as a service and software as a service. IaaS equips businesses with virtualized computing resources on the internet. To access the IaaS model, businesses collaborate with cloud providers. These providers offer and manage IT infrastructures for their clients and connect servers, networking resources, and storage. These companies use virtual machines and deliver their services to clients. Organizations subscribe to IaaS services for numerous reasons and get faster, flexible, and more cost-efficient workflow.

Other facilities offered by IaaS providers include:

  • Load balancing,
  • Monitoring,
  • Security,
  • Clustering,
  • Detailed billing,
  • Storage resiliency consists of replication, backup, and recovery.

Why Do Companies Rely on Infrastructure as a Service?

Five major benefits of IaaS include:

1. Cost

As IaaS eliminates hardware maintenance, shifting to this model saves immediate cost. Furthermore, these cloud services offer flexible pricing options. On top of cost-saving benefits, service providers immediately supply IT resources. This means businesses registered with IaaS service providers do not have to wait for resources. Also, they don’t have to purchase on-site servers and drastically scale overhead. It allows IT managers to resolve technical problems by consulting with their service providers instead of hiring professional technicians specific errors.

2. Security

When businesses utilize in-house software, they are at risk of network threats. These tools depend on the company’s resources, which can put business operations in jeopardy. However, businesses under a hosted cloud environment receive security from third-party service providers. In this condition, professionals handle network stability and provide solutions to the business without additional costs. The major advantage of Infrastructure as a Service binds service providers with physical and network security measures. As a result, service-providing companies make efforts to manage and secure system endpoints.

3. Scalability and Access

Hosted cloud services are agile, which means that they easily adapt to new technology and enhance infrastructure capabilities. As the business scales, bandwidth and the number of users increases. Therefore, companies can increase their infrastructure without migrating to the new systems. Also, hosting providers offer secure cloud environments to deliver additional access while preventing unauthorized interactions.

4. Service

Companies can optimize data access in real-time by subscribing to a reliable Infrastructure as a Service provider. The third-party cloud-hosted provider offers smooth IT infrastructure and services to companies. When a dedicated team monitors and manages hosting services and bandwidth, businesses receive high-speed network connections and prevent downtime.

5. Backup and Recovery

Businesses store their in-house data on local storage and backup locations. But in the event of a ransomware attack, companies risk losing critical data. However, when companies subscribe to an IaaS service provider, they don’t have to worry about data storage. In fact, a hosted company provides a secure cloud environment to protect their clients’ data. As a result, companies can recover their valuable data in case of disastrous situations.


Using IaaS, companies can obtain numerous cloud features and find solutions for their IT problems. Furthermore, IaaS service providers help businesses manage cloud applications, store data, and create backups.
