It’s a technology that everyone from IT professionals to business users and end-users can benefit from – ranging from personal entertainment to specialized IT tools. SaaS products can be accessed both by B2B and B2C users. According to the McKinsey & Company analysis, the SaaS market is expected to skyrocket to whopping billions of dollars in the next four years, signifying remarkable growth.

Characteristics of SaaS

SaaS products take advantage of the consumer web, which has a large user base, a robust infrastructure, and established security protocols. This makes SaaS solutions scalable, reliable, and secure.

Multitenant Architecture

SaaS solutions are built on a multitenant architecture, which means that multiple customers share the same instance of the software. This allows for more efficient and cost-effective management of software and hardware resources.

The SaaS market is rapidly growing and evolving, with new trends emerging every year. Some of the most notable trends include artificial intelligence, cloud-based solutions, mobile-first design, and the Internet of Things.

SaaS vs Packaged Software

SaaS is often compared to packaged software, which is software that is sold in a boxed format and installed on individual computers or servers. Packaged software requires ongoing maintenance and upgrades, while SaaS solutions are always up-to-date and maintained by the provider.

The Future of SaaS

The future of SaaS looks bright, with more and more businesses recognizing the benefits of this delivery model. As the market continues to grow, it’s expected that SaaS solutions will become even more sophisticated and user-friendly, making it easier for businesses to adopt and benefit from this technology.

Architecture for SaaS

Four Pillars of the SaaS Business Model

The SaaS business model is built on four pillars: centralized ownership, cloud-based hosting, subscription pricing model, and internet-based delivery.

Centralized Ownership

SaaS solutions are owned and operated by a single entity, which allows for more efficient management and maintenance of the software.

Cloud-based Hosting

SaaS solutions are hosted in the cloud, which eliminates the need for expensive hardware and infrastructure.

Subscription Pricing Model

SaaS solutions are typically sold on a subscription basis, which provides a predictable revenue stream for the provider.

Internet-based Delivery

SaaS solutions are delivered over the internet, which eliminates the need for physical installation and makes it easy for customers to access the software from anywhere.

SaaS software distribution model applications and services are often multi-tenant, which means that a single instance of the SaaS application is operating on the internet host servers. and that single instance serves each subscribing client or cloud tenant. All clients or renters will use the same version and configuration of the program. Even though different subscribing customers will run on the same cloud instance with a shared architecture and platform, data from different customers will be kept separate.

Because software as a service SaaS applications are frequently multi-tenant, the cloud service provider can handle maintenance, upgrades, and problem resolutions in a more timely, convenient, and efficient manner. Engineers can make critical modifications for all customers by using a single, shared instance rather than implementing changes in several instances.

Furthermore, multi-tenancy makes a greater pool of resources available to a larger group of individuals while maintaining important cloud qualities such as security, performance, and privacy.
