What is IaaS or Infrastructure as a Service?

Stackscale's servers for IaaS

Infrastructure as a service (IaaS) or Hardware as a Service (HaaS) is a cloud computing solution that consists of provisioning and managing computing resources over the Internet; such as servers, storage, networking and virtualization.

IaaS makes it easier for companies to develop big projects without investing a great amount of money on IT equipment. Thanks to it, companies can also save a lot of time and efforts.

What kind of resources are usually provided on IaaS?

Through the IaaS model, providers offer storage, computing capacity and network connectivity. It is also possible to offer specialized hardware such as FPGAs or GPUs for Artificial Intelligence (AI) projects.

What are the benefits of Infrastructure as a Service or IaaS?

IaaS is very advantageous for companies in terms of flexibility, efficiency, scalability and security. By “renting” your computing resources, instead of purchasing them, you save time and money, and increase agility.

Less capital expenses

In terms of costs and investments, Infrastructure as a Service is the way to optimize your expenses by delegating the management of your servers or nodes, storage and networking to a cloud computing provider. In some cases, you can also delegate the virtualization layer to your provider. At Stackscale, for instance, we offer IaaS with virtualization in the form of Private Cloud and IaaS without virtualization through bare-metal servers.

IaaS, what you'll manage and what your IaaS provider will manage

By outsourcing your company’s infrastructure, you will eliminate the capital investment of setting up, managing and maintaining on-premises data center. You will only pay for the resources you need and use.


When deploying an IaaS platform —also known as HaaS—, you are still in control of your applications, data, runtime, middleware and operating system (OS). You are responsible of purchasing, configuring and managing your software. But your IaaS provider takes care of housing, managing and monitoring the technical infrastructure, so that everything works perfectly.

Your IT team doesn’t have to worry about the infrastructure and can concentrate their efforts in tasks which are more valuable to your business. So, you will have more time to focus on your core business, while your provider’s specialized team do what they do best: taking care of the infrastructure.

Maximum security and redundancy

Security is another advantage of Infrastructure as a Service. IaaS and cloud providers set up their infrastructure in big data centers, which implement the strictest physical security and redundancy measures. All of which add up to the security measures put in place by IaaS providers. At Stackscale, for example, all elements within our infrastructure are redundant to provide a fault-tolerant service — from the power feeds to the nodes themselves.

Moreover, cloud and IaaS providers usually provide backup and Disaster Recovery (DR) solutions to help companies keep their data protected. This is also important in terms of costs, since companies would need to invest a great amount of money in order to achieve the high availability and business continuity providers offer.


With IaaS, you have more flexibility to scale your infrastructure, up and down, as your project evolves. You can adapt your computing resources to your needs anytime. Besides, you can prepare your infrastructure to meet seasonal demand, easier and faster.

Moreover, this kind of computing solutions allows you to always benefit from the latest technologies. Since IaaS providers, like Stackscale, have an expert team who stays tuned to the latest trends and technologies. We work with innovative technologies to offer maximum performance.

What is the difference between IaaS and virtualization?

The term “virtualization” only refers to the capacity to simulate a physical computer into a virtual environment; which enables greater security and an optimized use of the resources. IaaS is born from this concept, as a service model that allows making the most of the servers’ resources and virtualizing at more competitive prices.

To sum up, thanks to IaaS your company won’t be limited by its IT equipment. You can choose IaaS for deploying web applications, running a CRM, doing Big Data analysis, storing data, backups and Disaster Recovery plans, etc. You just need to choose the provider that better fits your needs and business strategy, so that you can make the most of it.
