What is Cloud Computing?
The cloud is not one thing, but rather a term that describes a computing model consisting of many parts. Find out more about what cloud computing really means.
Do you really know what the cloud is? To most of us, the cloud is a magical place where our data lives safely and securely. But obviously, it’s a bit more complicated than that. Cloud service is important to organizations that house data about their customers and their inventory, and it can be overwhelming – not to mention, expensive.
Maintaining on-premises IT infrastructure can be both costly and labor intensive. That’s why customer demand for cloud infrastructure as a service (IaaS) is accelerating as organizations continue to pursue digital strategies. However, top talent with cloud computing skills and experience is still hard to find.
Learning how to analyze, evaluate and design cloud service solutions requires a fundamental understanding of the different components that are commonly used.
Common types of cloud computing services include the following:
Infrastructure as a service can be a game changer, as it promises on-demand access to computing resources. Read on to learn about IaaS in cloud computing, the benefits it offers an organization, the challenges it may present and examples of IaaS.

The official IaaS definition is as follows: Infrastructure as a service (IaaS) provides compute, memory, storage, networking and related software, such as operating systems and databases, as a cloud service to replace traditional on-premises data center infrastructure.
Simplified, that means IaaS is essentially virtual servers that the customer rents from another company that has a data center. Essentially, IaaS promotes access versus ownership.
This solution provides the end user with flexibility when it comes to hosting custom-built apps or standard software while also providing a general data center for storage.
Customers can deploy IaaS in one of three different service models defined by the National Institute of Standards Technology (NIST):
Amazon Web Services (AWS) was the pioneer of cloud computing as we know it. According to Jeff Bezos, the mission of AWS was to provide the “application developers a set of dependable tools and a reliable infrastructure that they could build products on top of.” Microsoft (Azure) Google (Google Cloud), IBM (IBM Smart Cloud) and Oracle (Oracle Cloud) quickly followed suit. Today the range of cloud computing services is quite broad. Learn more about cloud computing types, solutions and vendors.
IaaS is advantageous to companies in scenarios where scalability and quick provisioning are key. In other words, organizations experiencing rapid growth but lacking the capital to invest in hardware are great candidates for IaaS models. IaaS can also be beneficial to companies with steady application workloads that simply want to offload some of the routine operations and maintenance involved in managing infrastructure.
Other advantages may include the following:
There are many benefits to using IaaS in an organization, but there are also challenges. Some of these hurdles can be overcome with advanced preparation, but others present risks that a customer should weigh in on before deployment.
Challenges may include the following:
Cloud business is booming. In fact, Gartner projects revenue in the cloud IaaS market to increase to $81.5 billion by 2022, up from $41.4 billion in 2019. Businesses are using IaaS in a variety of ways:
One example of scaling up and back on IaaS can be seen in retail. Many retailers expect traffic to increase in November and December, around the holidays. Having the ability to quickly add capacity during this peak time is important. The elastic nature of IaaS allows companies to ramp up when needed.
Another example of leveraging cloud infrastructure is storing security video files. Since video files consume a large amount of data, a management application is needed to store these files with easy access. IaaS cloud storage is an ideal solution for managing these files.
Companies in every stage of the business lifecycle are using IaaS solutions. From global enterprises to startups, the flexibility, scalability and cost savings are hard to beat.
Popular IaaS providers include Microsoft Azure, Amazon Web Services, Rackspace and Google Compute Engine.
Infrastructure as a Service (IaaS) is one of the three most common cloud computing services. IaaS is a pay-as-you-go service that often includes services, storage, networking and virtualization. But how does IaaS compare to its fellow service models?
Platform as a service (PaaS) consists of hardware and software tools built on top of an IaaS platform. It reduces the need for system administration and allows end users to focus on app development instead of infrastructure management.
Meanwhile, software as a service (SaaS) is ready-to-use software that’s available via a third party over the internet. Most modern SaaS applications are built on IaaS or PaaS platforms.
It’s not surprising that newer cloud models are entering the space that work alongside IaaS. Containers and serverless architecture are two such service models giving companies new options for how to run their applications. At this point, simple IaaS solutions continue to be the most mature option, but trend spotters are keeping their eye on containers and serverless architecture as new and emerging technology.
While the range of services offered by IaaS providers is massive and always evolving, the needs of the business should always be evaluated and prioritized before selecting a cloud service provider. Companies need qualified IT pros who have the ability to analyze, evaluate and design cloud computing solutions that fit their current and future needs.
