When to Use IaaS and When to Use SaaS

Whether your company is thinking about migrating to the cloud (or already has), you may already be familiar with it. The “cloud” is not just a popular buzzword, 90% of companies use some form of cloud computing.

Digging a little deeper, do you know about IaaS or SaaS? What they do or when to use them? This blog will give you the information you need to make an informed decision about IaaS and SaaS to best suit your organization’s needs.

What is IaaS?

IaaS or “infrastructure as a Service” refers to cloud-based infrastructure resources that are delivered to organizations via virtualization technology that help companies build/manage their servers, networks, operating systems, and data storage. IaaS give users cloud-based alternatives to on premise infrastructures so businesses can avoid investing in expensive on-site resources. In other words, IaaS is basically a virtual data center.

Taking advantage of IaaS allows your company to build and manage your data as you grow, paying for the storage and server space that you need to build hardware or software without having to actually host and manage the servers on-site. Say goodbye to that bulky server room! IaaS is very flexible and can be used in a variety of ways from hosting websites to analyzing big data. Clients can install and use whatever operating systems and tools they like too. Some examples of IaaS are Amazon Web Services, Google Compute Engine, and Microsoft Azure.

When Should I Use IaaS Services?

When you want to have complete control over your high-performing application.

There is still maintenance required with IaaS, which means you still have control. While the IaaS providers manage servers and storage, you get to manage the applications as they fit your organization.

When your company is growing and you’re not yet sure about the application and expect it to evolve over a period of time.

Companies of different sizes can benefit from IaaS. For smaller businesses and startups, this means you can avoid purchasing and creating software and hardware which can save you time and money. IaaS is flexible and scalable so you can make changes as your needs evolve or depending on traffic spikes and valleys.

When you want to increase your stability, reliability, supportability, and security.

When you use IaaS, there’s no need to maintain and upgrade software and hardware or troubleshoot equipment problems. With the appropriate agreement in place, a cloud service provider assures that your infrastructure is reliable, meets SLAs, and can also provide security for your applications and data that may be better than what you can attain in-house.

When you want to innovate rapidly or focus on your core business.

Using IaaS allows you to free up your team to focus on your organization’s core business rather than on IT infrastructure. It also allows you to create a computing infrastructure that can be ready in minutes or hours, rather than days or weeks it could take when your setting up internally.

What is SaaS?

It is projected that 73% of businesses will use SaaS, or “Software as a Service”, by 2021. SaaS refers to cloud-based software that is hosted online by a company, available for purchase on a subscription or license basis, and delivered via the internet.

All the software and hardware are provided and managed by a vendor, so you don’t need to install or configure anything. In other words, SaaS allows people to use cloud-based applications (such as Office 365, Adobe Creative Cloud, or Google Docs) via the internet with their login credentials.

When Should I Use SaaS Services?

When you want access to applications from anywhere.

You can access the software from nearly any device as long as you have internet access. SaaS is a great option for platforms that need both web and mobile access.

When you don’t want to have to worry about downloading and maintaining software on internal computers.

Because it is all managed from the third-party services, you won’t need to manage or deploy the software itself. It also removes the need for technical staff to install or perform updates because vendors manage all technical issues.

When you want to keep cost low.

Because you don’t have to outright buy the software licensing, your business can save money. SaaS allows you to “pay as you use” oftentimes in a monthly subscription. When you stop using the service, you can stop paying for it. You also have less of a need for technical support dedicated to your software.

Which Should I Choose?

The choice depends on your business goals, what you’re trying to accomplish and what your application needs. If you need a quick out-of-box software that’s quick to start and use, choose SaaS. If your business needs a virtual machine, IaaS will be a better fit.
