IaaS (Infrastructure as a Service), SaaS (Software as a Service) and PaaS (Platform as a Service) are three terms regularly thrown around in the world of cloud computing that can be misunderstood.
As cloud enthusiasts, we’re here to share the details on each of these categories of cloud computing services and help you understand their benefits!
Read on to discover what IaaS, SaaS and PaaS mean, how they work and how businesses, like yours, leverage them to keep one step ahead of competition.
IaaS (Infrastructure as a Service) is a form of cloud computing centered around making compute, storage and networking available on-demand. IaaS is best described as a collection of virtualised resources that allow users to build and run the applications they need the most. In short, you can replace all physical elements in your IT infrastructure with virtual ones, hosted in the cloud.
A common problem for businesses is that they face high, up-front expenditures on their IT infrastructure. Especially when experiencing growth, or a shift in workloads. IaaS permits end-users to scale or reduce their technology resources on-demand and pay-as-they-go, thus, allowing them to manage their IT costs better.
A great example of an IaaS that does it all is Microsoft Azure. Azure is among the fastest growing and largest public cloud platforms in the world, particularly as more and more businesses want to embrace modern workstyles.
There are lots of advantages to using IaaS, but here are a few key benefits:
SaaS (Software as a Service) allows users to use cloud-based applications over the internet. This means they don’t have to be hosted on your own infrastructure, they can be quickly and easily accessed using a web browser.
Similar to IaaS, SaaS can usually be purchased on a pay-as-you-go basis from the cloud provider. This cloud service provider then takes responsibility for managing, maintaining, updating and optimising all underlying infrastructure as well as the software delivering the service. Depending on the details of your service agreement, any data belonging to end-users should be indefinitely available and secured by the app.
There are lots of advantages to using SaaS, but here are a few key benefits:
PaaS (Platform as a Service) refers to the development and delivery of hardware and software tools over the internet, usually with the intention of supporting application development. Developers can purchase the resources they need from a PaaS third-party provider and access them over a secure internet connection and use them for building, testing, deploying, managing and updating an environment.
In short, rather than developers having to code everything from scratch, they can access pre-built blocks and customised solutions that support the rapid and efficient build of apps. A common example of a PaaS is Microsoft’s Azure SQL Database, which provides a range of services geared towards supporting database services, running on Microsoft technologies.
There are lots of advantages to using PaaS, but here are a few key benefits:
