What is SaaS, Software as a Service?

Let’s try to figure out, what exactly is SaaS and whether it is right for you or not? Well, SaaS is a short term for “Software-as-a-Service”. It is a usage model (or subscription based model) of a particular software or an app, that allows users to access and use software programs online, via the internet.

It is a cloud computing based concept, which allows you to use software applications without the need of installing them on your local machine. This model gives you more flexibility and power, because you access everything on the cloud (on the web). It also helps users in saving memory and cost.

SaaS is a software, online tool or application with its services, hosted on the cloud (web) and is made available and accessible to users (with its services), online.

This approach of distributing a software or an online application or tool or product through the web is better known as “SaaS in Cloud Computing”. Customers can access this software program using a web browser or a mobile app, rather than installing it on their own local machines or desktops or servers.

In a SaaS model, the software providers like Microsoft 365, Google Workspace, Salesforce, Zoom and others are responsible for managing the upkeep of the application software, servers, databases, and their underlying infrastructure. Clients and users often pay to access software on a monthly or yearly subscription basis.

These software applications are hosted on the cloud provider’s infrastructure and can be accessed through a web browser or API. SaaS business model helps in reducing IT expenses and improves flexibility, by removing the requirement for businesses to install and maintain software on their own servers. Making the solutions more scalable and efficient.

With the SaaS model, the cloud provider is always in charge of the upkeep for the network, storage, and server infrastructure requirements of running a software. As a result, businesses can concentrate on providing software applications rather than worrying about the infrastructure that supports them.

SaaS Examples: Some important examples of SaaS providers are:

• Productivity platforms like Microsoft 365 and Google Workspace,
• Customer Relationship Management (CRM) applications like Salesforce and HubSpot,
• Enterprise Resource Planning (ERP) tools such as NetSuite and SAP Cloud,
• Project Management solutions like Asana, Trello, and Monday.com,
• Email services providers,
• Accounting software providers,
• And more.

These are just a few examples common SaaS providers and the applications or solutions that SaaS providers often provide.

SaaS services has grown in popularity over the past few years as a result of its numerous advantages, which include cheaper initial costs, simplicity in deployment, scalability, and automatic upgrades.

What is Cloud Computing?

Let’s revise the basics of Cloud Computing, to understand SaaS in Cloud Computing more clearly.

Cloud Computing is the hosting and distribution of computing services, such as servers, storage, databases, networking, software, analytics, and more over the internet. Organizations can rent these services from cloud service providers rather than maintaining physical infrastructure on their own and use them as needed.

This makes it easier and cheaper to host and access powerful tools and more resources without need of maintaining them on their own. Which makes companies to provide services at the cheaper rates and at the effective costs.

Using cloud computing services and resources, organizations can simply and swiftly scale up or down based on their needs and user requirements with cloud computing. Both users and organizations only pay for what they really use. Especially, for smaller firms or those with varying demands, this may be more affordable than maintaining their own infrastructure.

Cloud Computing Services

There are three main types of cloud computing:

1. Infrastructure as a Service (IaaS)

IaaS service providers, provide access to computing infrastructure such as servers, storage, and networking. These services are used by the companies, that wants to build and manage their own IT team, systems, services and solutions.

For example: IaaS cloud computing services used by companies to host virtual servers on Amazon Web Services (AWS).

2. Platform as a Service (PaaS)

PaaS providers provides a platform for developers to build, test and deploy applications on their platforms, without worrying about managing the underlying or required infrastructure.

For example: Google App Engine, Microsoft Azure, Heroku etc.

3. Software as a Service (SaaS)

SaaS providers are the companies that provide software applications over the internet, which users can access through a browser on the web (cloud). This usage of software and it’s services are often offered on a subscription basis.

Example: Microsoft 365, Google Workspace, Salesforce etc.

What is SaaS in Cloud Computing?

Now after understanding SaaS and Cloud Computing concepts, we can say that:

SaaS in Cloud Computing is a concept and a way, in which software applications are hosted on the cloud (on the web) by a third-party services provider and is used by end users through internet, without installing the application on their local machines or servers.

Customers and users access the software program through a web browser or other application interface, whereas, the provider maintains the software’s access, infrastructure, security, and maintenance in the SaaS model. Customers pay a subscription fee to utilize the software online rather than acquiring and installing it on their own local machines, servers or infrastructures.
