Cloud computing in the past decade has catapulted to previously unimaginable levels of significance and importance in the world of technology. Just a few decades ago, it was almost unimaginable that a computer could be able to access data that is not physically stored on the computer itself or an adjoining local server. Let us look into, SaaS in Cloud Computing.
However, today, from the simplest word editing software to the most complex coding applications, individuals can easily access, use, and process data stored on remote servers on the internet. Such is the power and ease with which cloud computing has changed the way we work and use the internet. There are three primary cloud computing models in use across the world and these are Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). Read the rest of this article for a better understanding of what is SaaS in cloud computing.
In this article let us look at:
There are several forms of cloud computing in existence and one of them is the SaaS model (Software-as-a-Service). In simple words, SaaS in cloud computing is a delivery model where software providers make applications available to customers for use over the internet with the help of SaaS cloud servers.
SaaS in cloud computing functions on the primary basis of subscription where users subscribe to SaaS software provided online that eliminates the need for them to purchase and install the applications on their device or computer system. These users can easily use their login credentials to access these SaaS applications via the internet instead. The SaaS cloud providers make the SaaS platform and the applications hosted on it available only to those who have acquired a valid subscription from them.
The characteristics of SaaS in cloud computing are such that there are plenty of SaaS advantages and disadvantages. Some of the main advantages of opting for SaaS cloud services as a customer or employing SaaS technology as a software provider are as follows.
SaaS software, despite all its benefits, also comes with a fair share of drawbacks to users and businesses that opt for such services.
SaaS is a very popular cloud computing model today and there are several popular Software-as-a-Service examples. A simple electronic mail service provided to users such as Gmail is a classic example of SaaS.
Other SaaS application examples include the Office 365 suite provided by the tech giant, Microsoft, popular video streaming services such as Netflix and Amazon Prime Video, cloud storage and transfer services such as Dropbox and OneDrive, and website building software such as Wix or WordPress.
These are just a few examples of the large number of SaaS applications and software programs that can currently be accessed by people around the world. A true test for whether a service is in fact part of the SaaS model would be to ascertain whether it is based on a subscription payment model, the flexibility and ease of access, and whether or not remote cloud servers are used to make the software available to users over the internet.
Software-as-a-Service (SaaS) cloud computing models are changing the world of technology and greatly reducing the dependence of software applications on local hardware systems. The flexibility, cost-efficiency, and ease of usage of these services are unparalleled and have thereby made them extremely popular around the world. For all their advantages, this model also has several potential problems that might cause inconveniences to users such as the lack of control over updates and data storage and lack of vendor flexibility.
We hope that this article has helped you get a better understanding of what SaaS cloud computing is and make an informed choice as to the suitability of SaaS applications to your business or enterprise.
