Cloud technologies have revolutionized the software application development and delivery process. As more and more companies are realizing the benefits of reduced infrastructure costs, automated production deployments, and increased security in the cloud, commercial off-the-shelf products are on the rise to provide business-ready solutions to the customer. The products that were traditionally developed, bundled, and deployed on the premises of the customer or hosted in-house to provide the applications and services are on the transformation path to the cloud. These Prem applications always have challenges as the customers are on different versions of the product, on different infrastructure versions, and specific customizations for the customer need more maintenance; scaling the applications based on the usage is often more a reactive approach than a proactive approach.
Software-as-a-service (SaaS) applications alleviate the vendor selling the product from the above challenges as all its customers are on the same version of the cloud infrastructure through patches and upgrades, which the customers can’t avoid. The ability to scale up or down depending on the customer's requests is proactive. Also, it provides enhanced customer experience by releasing new features regularly without the customers having to wait long for their favorite features.
