In this fast-growing world, businesses are shifting from on-premises software to cloud services. It is happening because bringing data to the cloud makes it simpler for companies and employees. This type of technology is growing more users worldwide. 

However, you must know the difference between Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). These services have their advantages and specialties you need to know whether it is good for your industry.

Unlike decades ago, your organization now has more chosen preferences for software. The cloud will make tasks more efficient and profitable. It is important to contemplate the perfect cloud for your business.  Take a look at this clear visual chart from Soluno.

These technologies are developing and you must know the difference between the three types of services. If you are shifting to the cloud, we described the details of SaaS, PaaS, and IaaS and how it will benefit your company.

Software as a Service (SaaS) 

    Occasionally called Web-based software, on-demand software, or hosted software, SaaS or cloud application services provide applications over the Internet and are controlled by a  third-party vendor. The application’s access, including security availability and performance, is managed by the provider.  You do not have to install and maintain software since you can access it online. There is no complicated software and hardware management in this type of cloud. 

    Among the cloud service options, SaaS is the most commonly used in the cloud market due to its simplicity. It lets users easily create website content for both web and mobile access. You will easily make changes without carrying the burden of software issues. The reason why there is no need to download or install it is that the majority of apps run directly through a web browser.  Basically, all you need is an Internet connection to establish an SaaS system.

Responsibilities of SaaS 

      The responsibilities of providing a SaaS comes in different ways. Here is the visual representation of this model from Researchgate.

Examples 

    At Third Pillar, we partner with Salesforce, the world’s #1 Customer Relationship Management (CRM) software, and DocuSign, the world’s #1 Electronic Signature and Agreement Cloud. These solutions provide ways to improve businesses through its one-platform-for-all technology.

Their Application Programming Interface (API) allows users to set up and connect the software to websites, mobile apps, and customer workflows. DocuSign utilizes different applications electronic signature, document preparation, contact management, guided forms, and clickwrap agreements.  

Platform as a Service (PaaS) 

     PaaS or cloud platform services provide hardware and software tools online that users utilize to develop an application.The provider hosts these tools on its own infrastructure and it removes the need for developers to install in-house hardware and software to develop or manage new applications.  It is fit for enterprises that want custom apps and at the same time, reduce expenses and save time from assistance with rapid deployment and drastic development.

PaaS tools are known to be simple and convenient. If you choose PaaS, you will have to pay on a per-use basis. What makes it stand out is that it removes the expense and complexity of buying, configuring, and controlling all the tools needed to function applications. However, PaaS does not replace the software development or infrastructure of your company.

Responsibilities 
     
IaaS has many responsibilities in providing certain services. Look at the red boxes below in the model from Researchgate.

Examples 

     Three examples of popular IaaS are Amazon Web Services (AWS), Microsoft Azure, and Google Compute Engine (GCE).  These are the cloud computing services that provide solutions to industries of all sizes. 

     AWS is a comprehensive cloud platform that offers many featured services from data centers around the world. This platform provides technologies such as compute, storage, databases, analytics, machine learning, artificial intelligence, Internet of Things (IoT), and data lakes

   Microsoft Azure is a public computing platform that serves compute, analytics, networking, and storage. It also offers technologies that support industries compatible with their tools. Aside from these services, specific third-party vendors make software available through Azure. 

     GCE lets clients use Google’s physical hardware in running workloads. They provide virtual machines (VMs) and can be managed through an API, Web console, or command-line interface. This platform allows admins to pick the place where specific data resources will be used and stored.

What is the right service for you? 

      There are many benefits to using SaaS, PaaS, and IaaS. Although, you must think about the service that suits your business the most.  Then start to take into a deeper look into the types of cloud services that will enhance your relationship with customers. 

      If you want to have a cloud application that is provided by a third party vendor, SaaS is your best solution. However, if your business wants to create and release an app, PaaS is a perfect match. If your organization is more of the hands-on type, then IaaS is a good solution.
