Saas, PaaS, and IaaS are three popular types of cloud computing. For e-commerce businesses, these three terms are of great essence. While Software as a Service (SaaS) has a market share of 24% of all workloads, Infrastructure as a Service (IaaS) accounts for about 12% of enterprise workloads, and Platform as a Service (PaaS) occupies around 32% of all workflows.
These cloud computing formats have been experiencing demand in the last few years – SaaS has grown by 10% from 2016 to 23% in 2020, and IaaS has grown by about 6%. Paas is the clear winner amongst the three and with all the potency to grow further in this decade.
Until about a few years ago, most of the enterprise IT ecosystems were located on-premise. Clouds did not have any relevance, not at least in the IT landscape. Today, things are so different – most of our online activities happen on the cloud platform.
For businesses today, the choice of the right IT infrastructure becomes crucial for the business's success. That is why it is important to gather more information about all the three to make the right choice; enterprises need first to know the scope of each of these three types and understand the difference between SaaS, PaaS, and IaaS.
Service as a Service – in this model, the services are in the Cloud, and end-users and businesses can access the services using cloud-based tools on a daily basis.
Platform as a Service – in this model, the platform is available on the Cloud. Thus, developers and businesses can use resources from the Cloud, develop, build, and host apps in the Cloud.
Infrastructure as a Service – in this case, various elements of the IT ecosystem are present in the Cloud. For example, businesses have their servers present on the Cloud or have data storage within the Cloud.
All of these devices can be accessed using browsers from a smart device. Compared to on-site apps and software systems, cloud-based systems can be accessed anytime and from any place. For on-premise, there is a need to invest in a license and renew it on a regular basis. With cloud-based models, there is a subscription fee that enterprises and individuals need to pay.
Today we are going to learn more and in-depth about the difference between all three cloud computing models.
This model has services or Software present on the cloud, where the services are delivered to the end-users through the internet. The SaaS development companies make these services available to its end-users on a subscription-based model.
SaaS has been a popular model for quite some time now. Services are usually not required to be downloaded or installed on individual devices. The service providers can scale up service offerings to unlimited scales, and these are quite easy to manage access and use. Such models are becoming more and more popular these days, where many employees need to work remotely. Also, such systems are a blessing for a global team.
Examples of SaaS
It is an online image editing software tool-cum-animation maker. Creative people can use the cloud-based tool to create impressive posters, logos, collages, quotes, invitations, marketing flyers, etc. The free-to-use tool has about a million-plus templates and a PixBot to help create images.
It is another interesting example of SaaS where multiple users from the same organization can download, upload, and share documents and files.
Pros of SaaS
Cons of SaaS
For developers, PaaS makes a big difference in their workflow. When developing an app on the local drive and getting it deployed online, developers often face major issues. Resolving such issues involve complicated and multiple steps. Using PaaS, development, and deployment can happen back to back seamlessly.
Not just that, being in the Cloud, the entire team of developers can communicate and collaborate in real-time, track progress, update apps, and customize them without any hassle. PaaS platforms have the potential to be scalable if the developers' community adopts the tools easily.
Examples of PaaS
This tool enables developers to develop web apps and host them on Google-managed cloud centers.
It is another common example of PaaS. While developers can use the Platform to build apps of various scales, they can also integrate on-site apps with Cloud. More than 1,300 apps have been made using SAP Cloud.
Pros of PaaS
Cons of PaaS
With IaaS, organizations manage their entire network and various elements like servers, operating systems, storage spaces, etc., in the cloud. Thus, organizations do have to indulge in the physical management of servers and networks. Using the Application Programming Interface, they can easily manage their entire IT assets and resources in the Cloud.
IaaS can be best understood as a server or a series of servers spread across the world that the IaaS providers manage. Organizations that use such services pay for services rendered on the cloud as well as server and storage space. They also save time and money vis-à-vis hosting and managing servers on-site. IaaS products include virtual servers, storage spaces, and networks.
Examples of IaaS
Offered by Amazon, organizations can purchase the services on a subscription-based model. They can then use the services for data storage and delivery of content through cloud computing.
It is another great example of IaaS. Organizations can use this Platform to run their operating systems like Windows or even SAP or Oracle. Organizations also use the Platform to improve operational efficiency by using technologies like Artificial Intelligence.
Pros of IaaS
Cons of IaaS
Cloud computing is the way to go. All the three 'as-a-services' are great and help improve organizational productivity and workflow efficiency.
