Cloud computing has changed the way we do business. By making IT infrastructure, platforms, and software programmes accessible via the internet it has altered how organisations store, access and manage data. Giving organisations flexibility and scalability to match their ever-changing needs. Cloud computing is made up of layers that can be described as a stack.
The third common cloud computing model we are looking at alongside IaaS and PaaS is Software as a Service (SaaS), also known as web-based software, on-demand software, or hosted software. SaaS is a convenient method of software delivery and licensing via an online subscription. Investopedia defines Software as a Service as a software licensing model
In the IT sector, acronyms are prolific, and you will be forgiven for getting lost in all the coded jargon. A group of such acronyms are those that stand for the main forms of cloud computing service models available: IaaS: Infrastructure as a Service, PaaS: Platform as a Service, and SaaS: Software as a Service.
Infrastructure as a Service, or IaaS is one of three main forms of cloud computing service models available, alongside Software as a Service, and Platform as a Service. Google defines IaaS as a cloud service model that offers on-demand infrastructure resources, such as compute, storage, networking, and virtualisation, to businesses and individuals via the cloud.
