![]() ![]() With these resources taken care of, businesses can take this infrastructure and build on it, installing operating systems, creating databases, and storing files. IaaS providers can deliver and manage services like firewalls, network connections, load balancers, data storage, and identity management. Through IaaS, businesses can access the amount of computing, storage, and networking power they need over the internet from a third-party provider, giving them the freedom to access an IT environment that suits their needs, and can be scaled up or down as required without forking out for additional servers or hardware. This service enables companies to get rid of the hassle of having to operate infrastructure and hardware of their own. IaaS gives businesses the option to have a vendor provide and manage these things on their end. Traditionally, these aspects of computing would be the responsibility of an organization’s own IT department, housed and managed under its own roof. Infrastructure is the digital scaffolding that supports a computer system the really important back-end things like servers and storage, networks, security, and data centers. SaaS software isn’t run from your machine, so as long as you can connect to the internet, you don’t need to buy or maintain hardware, which saves you time and money.īefore we go into what Infrastructure as a Service is, it’s worth taking a second to define exactly what we mean by infrastructure when it comes to computing. If your computer isn’t powerful or new enough to run certain software, you don’t have to miss out. Plus, because they’re powered by the cloud, SaaS products are more powerful and capable of much more than a traditional version (which can only do as much as your computer can process). Generally speaking, software vendors are focusing more on cloud versions of their products, so embracing SaaS means you get access to the best and newest features. Always up to dateĪs it’s based on the vendor’s own servers, you’ll always be presented with the latest version of your “as a service” product, without you having to manually download and install updates. With a SaaS version, you just log in to a website from any device-whether that’s your laptop, your phone, your tablet, a public computer, your work computer, your mom’s computer… you get the idea-and you can use the software. ![]() If you have a piece of software installed on your home computer, that’s the only place you can use it. Not only does this make the software more accessible, but it also means that if you decide you don’t need it anymore, you can simply cancel the subscription without being lumbered with an expensive tool that you don’t use. Instead, you can pay a smaller price on a monthly or yearly basis. You don’t have to have a big chunk of cash upfront to buy the software. The benefits of “as a service” models are enormous. Instead of paying for the software outright, customers pay a subscription fee to access it Word then becomes less of a product people purchase, and more of a service they pay to use. Now, Word is available “as a service.” Rather than having to download Word and use it on a single device, customers can use a SaaS version that’s hosted on Microsoft’s internal servers. That software would be run on, and therefore only accessible from, the computer that it was installed on. If you wanted to update Word to get new features, you’d have to download the update and install it on your computer. A one-time purchase, after handing over your cash you’d be able to use Word forever (this kind of software purchase is known as a perpetual license). This purchase probably entailed buying a disc containing the software, installing it on your computer. These services are accessed through the internet.įor example, a few years ago if you wanted to be able to create and edit documents, you might have purchased Microsoft Word. “As a service” simply means a facility, usually related to IT, computing, or telecommunications, that’s available to its users as a service, rather than something they install and operate themselves through their own hardware.
