SaaS is the acronym for software as a Service, and SaaS in cloud computing delivers cloud-based applications to the end-users over the internet.
Simply put, it uploads software to the cloud that gives quick access to the users. Or, to make it easier for you, it is like you are travelling via a bus where you will be paying a nominal amount for travelling and other passengers will also be there. You may be surprised to know, but SaaS applications make up 70% of the software used.
This cloud model runs on the cloud and could be used with the help of a monthly or annual fee. It eliminates the need to download and install the application; instead, you can directly run it over the web browser.
What are the benefits of SaaS services?
SaaS services give you the freedom of accessibility, and you can use them from anywhere, and it eliminates the constraints of on-premises software.
It is super affordable and discards the cost of purchasing, installation, upgrading, maintenance of the software. You simply have to use the software, that's it!
SaaS is available in a ready to use model and is functional in no time. All you need is to sign up and access the tool.
What are the limitations of SaaS services?
1. Inadequate data security
Data security is one of the biggest concerns that companies face with SaaS-based applications. Data security should always be considered before opting for a SaaS service, as issues like identity and access management can need to be addressed before trusting the third party.
2. Insufficient performance
A browser-based application that is running on a remote data centre may lag behind the performance in contrast to an application that is running on an employer's desk.
SaaS Examples: Microsoft office 365, Google Apps, Dropbox, Slack, MailChimp, Oracle, GoToMeeting, etc.
