What is SaaS?
Let us first understand what SaaS is with the help of an example, think of SaaS as a buffet of software options, where you only pay for what you eat. You can try out different applications and services as needed, without having to worry about the cost of licenses or the hassle of installation.
In the tech world, Software as a Service is changing the way we interact with technology on a daily basis. No longer do we need to install software on our own computers or pay for expensive licenses. Instead, SaaS provides access to a wide range of software applications and services over the internet, on demand.
From email and project management to HR and customer relationship management, SaaS offers solutions for just about every aspect of your business or personal life. This delivery model has become increasingly popular due to its increased efficiency, flexibility, and cost savings.
SaaS Architecture
SaaS, or Software as a Service is a cloud computing model that delivers software applications over the internet. But have you ever wondered what happens behind the scenes to make it all work?
Think of SaaS architecture as a delicious recipe for software delivery. Just like a recipe, it has a set of ingredients that, when combined in just the right way, results in a delicious dish. In SaaS, these ingredients are made up of servers, storage, databases, and networks. The provider takes care of all the ingredients and ensures they’re properly combined and cooked to perfection. All you need to do is log in and enjoy the delicious software applications.
Technically speaking, SaaS architecture is built on a multi-tier model, which includes:
- Front-end tier: This tier is responsible for presenting the user interface and handling user interactions. It typically consists of HTML, CSS, and JavaScript
- Application tier: This tier is responsible for executing the business logic and performing data processing. It is typically built using a combination of programming languages and frameworks.
- Database tier: This tier is responsible for storing and retrieving data. It is typically implemented using a relational database management system (RDBMS), NoSQL databases, or a combination of both.
All three tiers are hosted on servers managed by the SaaS provider, and they communicate with each other over the internet using standard protocols, such as HTTP and HTTPS. This enables customers to access the software applications from anywhere, using a web browser or a mobile device.
SaaS architecture is designed to be scalable, secure, and highly available. The provider uses load balancing and caching techniques to ensure that the application can handle increasing traffic. Data is stored securely in the database tier, and the provider implements appropriate security measures, such as encryption and firewalls, to protect the data.

Difference between Iaas, PaaS, and SaaS
IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service) are three different cloud computing models that offer different levels of control and responsibility to the user. Let’s see the differences among them:
| IaaS | PaaS | SaaS |
| Provides basic computing infrastructure such as servers, storage, and networking. | Offers a platform for developing, testing, and deploying applications. | Delivers ready-to-use software applications over the internet. |
| The user has full control over the infrastructure. | The user has control over the platform and the deployed applications. | The user has limited control over the software, but the provider takes care of maintenance and updates. |
