PaaS and SaaS are just two of the major categories of cloud computing provided by a third-party.
PaaS
Programmers want to focus on code – not on building and maintaining infrastructure. That’s why platform as a service (PaaS) is so incredibly popular. Offered via a cloud service provider’s hosted infrastructure, PaaS users are traditionally able to access a software development platform via a web browser. Easy access to a suite of development tools means programmers can program – and businesses can quickly deploy new applications.
SaaS
Software as a service (SaaS) is the most commonly used option for businesses in the cloud market. The reason? It’s easily accessible – all you need is an internet connection and a browser – and it’s hands-off. The SaaS delivery model requires vendors to manage all the technical issues – meaning customers don’t need to lean on their in-house IT expertise.
