Discover the Benefits of IaaS

IaaS is an business intelligence service on demand, where infrastructure services such as storage and virtualization are provided by a third party through the cloud and Internet, according to customer needs. It’s a completely free service, similar to SaaS.

Definition of IaaS (Infrastructure as a Service)

IaaS is a type of cloud service where companies can access essential resources, networking, and storage without having to purchase, install, or maintain these resources on-site. Instead, most IaaS providers offer pay-as-you-go models, where companies rent computing resources. These resources are then accessible via any secure internet connection. IaaS is a full self-service solution to manage computers, networks, storage, and more.

How to Use IaaS

There are various ways to use IaaS. Its use will vary depending on company size, industry, etc. For example, startups and SMEs may prefer IaaS to save time and money on buying and building hardware and software. Larger companies like having full control over their applications and infrastructure but only want to buy what they consume or truly need. To clarify, here are some examples of how IaaS can be used in business:

• Never lose your data: IaaS simplifies backup and recovery system management by allowing users to scale resources according to their storage needs.

• Better testing and development: Successful software implementation must first be tested and evaluated. IaaS allows companies to set up test environments tailored to their specific product needs and deploy them faster, enabling quick and easy scaling of computing power and other resources. Developers can define infrastructure as code, just as code.ge describes functionality.

• Data analysis: IaaS can efficiently combine big data and business intelligence, allowing companies to gain competitive insights from structured or unstructured data sources (social networks, email, images, etc.).

Why Use IaaS?

IaaS shares some advantages with PaaS and SaaS, but some are unique to IaaS. Here are reasons why you should consider using IaaS (or other cloud services like SaaS and PaaS):

• Reduce operating costs: Hardware and maintenance costs are a major expense for companies. IaaS eliminates these costs and allows users to pay only for the resources they use.

• Keep your Business running smoothly: Effective business continuity depends heavily on available technology. By owning the infrastructure, cloud providers ensure that essentials remain available during accidents and disasters, improving continuity for users.

• Increase reliability: When a company pays a cloud service provider for infrastructure resources, it commits to a certain service level. Service Level Agreements (SLAs) guarantee the availability and reliability of business technology without the need for server maintenance, network security updates, or hardware troubleshooting. All these tasks are handled by the cloud service provider.

• Enable rapid scaling: Cloud service providers often serve multiple organizations at once. This means you need a large amount of computing resources ready to meet your clients’ changing needs. When companies see demand fluctuate, they can easily scale resources up or down and only pay for what they use.

• Give developers control: IaaS is usually driven by programming or code. This means developers can define their own infrastructure requirements using Infrastructure as Code. This is done when code is deployed in test and production environments. It’s sometimes said that responsibilities have shifted left or forward in the implementation process, moving from operational roles to developers or DevOps teams.

Do Not Confuse

Note, don’t confuse the different types of cloud computing: SaaS, PaaS, and IaaS. To clarify, here’s a summary table:
