IaaS Vs PaaS Vs SaaS: A Guide to Cloud ‘As-A-Service’ Models
IaaS Vs PaaS Vs SaaS: A Guide to Cloud ‘As-A-Service’ Models
With all of the IT acronyms getting thrown around, it can be difficult for a modern business to keep up with all of the HTTPs, LANs and ISPs, to name a few. Cloud services are no different. You might have heard of ‘IaaS’, ‘PaaS’, and ‘SaaS’, but what exactly do they mean, what’s the difference, and which one should you choose?
Our experts at CAB IT Services have put together this guide to answer these questions and help you unscramble the technical jargon and make a decision on how best to implement cloud software in your business.
What is Cloud Computing?
‘The cloud’ refers to any servers that are accessed remotely via the internet. These servers are located all over the world, meaning that businesses don’t have to find space for physical servers. The ‘as-a-service’ model revolves around the cloud, with businesses paying for access to specific software and features that are accessed through the cloud.
One of the main benefits of cloud computing is the convenience. Any of a business’ devices that are connected to the cloud can access all files and applications without lengthy installs or hefty storage requirements. The cloud is streamlining many business practises – this is why as-a-service models have become commonplace.
A prime example of this: Microsoft 365 Sharepoint. Microsoft 365 Sharepoint allows entire teams to work on a document simultaneously, rather than laboriously sending copies about (and inevitably losing some saves!)
So, let’s break it down.
What is Infrastructure as a Service (IaaS)?
IaaS virtualises the various storage and networking infrastructure that businesses have historically had to house on bulky physical servers. Infrastructure as a service models take care of all your storage needs remotely. Most IaaS offer pay-as-you go models and are fully flexible, allowing you to pay for exactly the amount of infrastructure that you need, and scaling it up or down as your requirements change. This can help businesses avoid spending money on expensive on-site servers and networks, saving both space and resources.
Using IaaS provides a whole host of benefits, but it needs to be implemented correctly in order to be secure (you’ll be storing a lot of data on the cloud, after all). Many businesses rely on cloud computing specialists in order to host encrypted servers and ensure that your data is stored safely.
Who’s IaaS Best For?
Any business that has its own network infrastructure will benefit from upgrading to IaaS. Small companies & large companies alike use IaaS; flexible pay scales mean that you can pay for what you need as you grow.
What is Platform as a Service (PaaS)?
PaaS refers to a cloud-based platform that can be accessed by developers to provide the requisite framework to build custom applications. Using PaaS cuts out all of the usual hassle of storage, management & data serving, allowing developers to focus on their job. It also provides the distinct benefit of giving developers a head start when creating applications, as PaaS provides solid foundations on which to build (without having to write extensive code).
Generally easy to run, PaaS is often the most efficient way for a developer to create a unique application, as it handles all menial patching and updates, encouraging developer creativity. A good analogy for PaaS is a recording studio – it’s much cheaper for an artist to record an album in a hired studio versus building a studio from scratch to record in.
Who’s PaaS Best For?
A popular choice for businesses who want a head start when creating an application, PaaS allows companies to do this without spending a fortune.
What is Software as a Service (SaaS)?
Perhaps the solution with the least micromanagement, SaaS provides software over the internet, removing any requirements for file management and downloads – everything is handled by the supplier. Usually, businesses will create logins that allow employees to access the software as and when it’s required.
Most SaaS is designed to be intuitive and ready to use out-of-the-box, with customer service available to help whenever you require. SaaS takes all responsibility away from the business. The provider is responsible for solving any issues with the software, with the idea being that it’s always ready to use at your leisure.
Payment models are often flexible, with many SaaS providers offering monthly subscriptions that are scalable to your requirements.
Who’s SaaS Best For?
SaaS is perfect for companies who want a specific piece of software, but don’t have the time to manage it. Boiled down, SaaS is paying both for access to the software, but also for the convenience of not having to worry about keeping it up-to-date and working.
IaaS Vs PaaS Vs SaaS – What’s the Difference?
When broken down, IaaS, PaaS and SaaS are varying degrees of the same thing, offering different benefits/limitations. Many businesses rely on a combination of the three in their day-to-day functions, with the most common combination being that of IaaS and SaaS.
- IaaS takes care of the network and servers, but leaves everything else in the business’ hands, providing no specific functionality over cloud storage, but allowing for the greatest degree of flexibility.
- PaaS provides the business with the overarching platform to manage and handle development work, saving all work on the cloud.
- SaaS tends to be more specific, offering a full package experience, but usually only handling a specific role (e.g., DocuSign or Dropbox).
