The cloud computing software as a Service (SaaS) model provides end users with a Software as a Service application. Refers to software implemented on a hosting service and accessible via the Internet. There are several SaaS applications listed below:

Invoicing and invoicing system.

• Customer relationship management (CRM) applications

• support applications

• Human Resources (HR) Solutions

• Some SaaS applications, such as Microsoft Office Suite, are not customizable. SaaS offers an Application Programming Interface (API). This lets developers create custom applications.

The Characteristics of Cloud Computing Software

These are the characteristics of the SaaS service model:

• SaaS makes software available on the Internet.

• The provider maintains software applications.

• Software licenses can be subscription-based or usage-based. And it is billed regularly.

• SaaS applications are cost-effective because they do not require maintenance by the end user.

• They are available on request.

• They can be expanded or reduced on demand.

• They update and update automatically.

• SaaS offers a shared data model. Therefore, multiple users can share a single infrastructure instance. As a result, there is no need to code functionality for individual users. And allso

• All users are running the same version of the software.

Advantages of Cloud Computing Software

SaaS has proven beneficial in terms of scalability, efficiency, and performance. Some of the benefits are list below:

Modest Software Tools

• Efficient use of software licenses

• Centralized management and data And also

• Provider Managed Platform Responsibilities

Subtle Software Tools – Cloud Computing Software

SaaS application deployment requires little to no client-side software installation. Which yields the following benefits:

• No complex client-side software packages needed

• Little to no client-side configuration risk And also

• Low cost of distribution

Efficient use of Software Licenses

A customer can use one license on multiple computers in different locations. This lowers the overall cost. Additionally, a license server is not require as the software runs within the provider’s infrastructure.

Centralized Management and Data Cloud Computing Software

The cloud provider stores the data centrally. However, cloud providers can store data decentrally for redundancy and reliability.

Vendor-Managed Platform Responsibilities

All platform tasks include backups, system maintenance, security, hardware upgrades, and power management. The cloud provider handles these. The client does not eat to worry about that.

Multi-User Solutions

Multi-tenant solutions allow many users to share one instance of resources. They keep everything separate for each user. Customers can customize their apps without affecting core functionality.

Issues

There are several issues associate  with SaaS, some of which are list below:

Browser Risks

network dependency

Lack of portability between SaaS clouds

Browser Risks

If a customer visits a harmful website, their browser might get infected. This can risk their access to the SaaS application and compromise their data.

To reduce risks, the customer can use several browsers. They might dedicate one browser for SaaS applications. Alternatively, they can access SaaS apps through a virtual desktop.

Network Dependency

The SaaS application can only be delivered when the network is permanently available. The network needs to be reliable. However, neither the cloud provider nor the customer can ensure that reliability.

Lack of portability between SaaS clouds

Moving workloads from one SaaS cloud to another isn’t simple. Each vendor has different workflows, business logic, user interfaces, and support scripts.

Open Saas And Soa – Cloud Computing Software

Open SaaS uses these applications, which are grown using an open-source programming language. These SaaS applications can run on any open-source operating system and database. Open SaaS has several advantages that are list below:

• No license required

• Low implementation cost

• Less vendor lock-in

• More portable applications And also

• more robust solution

Conclusion

Cloud computing software includes applications offered as services online. It also covers the hardware and software in data centers that support these services. The services themselves have long been called Software-as-a-Service (SaaS). However, data centre hardware and software are what we will reach as a cloud.
