Software as a Service (SaaS): How It Works in Cloud Computing

Introduction

Software as a service (SAAS) is the delivery model of the cloud computing under which SAAS delivered over the Internet on a pay-per-rent basis. SAAS could also be the central hosting mechanism, which offers applications and data provided, maintained and hosted by vendors. Its popularity greatly raised due to the benefits of economical cost, high availability, flexibility, etc.

Basic Concept of SaaS

With traditional software users need to purchase the licenses, download and install the programs and upgrade them when the providers release the new version. In the case of SaaS the provider eliminates this work for the customer by providing application to users on a server remote hosted by them. All you have to do is just subscribe for the service and access it via the internet. The provider will look after all the back-end elements such as servers, database, security, and application upgrade and the customer will just only look after using the application.

How Software as a Service Works in the Cloud

In order to easily explain how SaaS works, we must put emphasis on the cloud infrastructure that is on the root of SaaS. The Software as a Service (SaaS) application would operate from cloud servers and the companies who look after these cloud services are Amazon Web Services, Microsoft Azure, Google Cloud.. They maintain the servers and storage, and answer the user’s questions, by receiving and responding to them in real-time. When a customer logs into a SaaS application, the system sends the request to a cloud server. The server processes the request and returns the response, allowing the client to access the application within a few seconds if everything works properly.

Multi-Tenant Architecture in Software as a Service (SaaS)

Another essential element of SaaS is the multi-tenant architecture. Multi-tenant architecture refers to situations when different applications or organizations use one or more common infrastructures but do not see or access the data of one another. Operational expenses for service providers are reduced while effectiveness increases. An instance can be the use of thousands of companies of one application software like customer relationship management (CRM) and each user has access only to his or her own customer information.

Updates and Maintenance in Software as a Service (SaaS)

SaaS benefits from constant updates. The software provider takes responsibility for enhancing the software by including fixes for problems or new functionalities in the product on an ongoing basis without the involvement of users. Providers deliver all updates through the cloud, so users always access the latest version of the software. This improves efficiency and enhances the user experience by removing the need for manual installations and reducing system downtime.

Accessibility and Scalability of Software as a Service (SaaS)

SaaS applications can be accessed via any internet enabled device such as laptop, tablet and smartphone. As remote working becomes more popular this type of accessibility of applications makes them ideal.

Furthermore, SaaS applications are scalable. This means that as your business expands and evolves you can adapt to changing needs by increasing your subscription or service usage without having to adjust the underlying infrastructure.
