How Exactly Each Type of Cloud Computing is Different from Other

September 17, 2020

Every cloud computing service relies on the same remote infrastructure for a conceptual framework. Servers located in the data center power this framework. As there are a lot of similarities between them, we can consider this computing system or Types of Cloud Computing Services as a pyramid with three layers. Every layer has its own specialty. However, the basic infrastructure is the same. Lower layers of the cloud computing system are broader, representing their customizability, versatility, and have a wide application range. The upper layers have a specific purpose to follow, so they are narrower. Below, you will find three Types of Cloud Computing Services and their difference to understand all the layers individually:

1.    IaaS

This cloud computing system is the foundation of the pyramid. Infrastructure as a Service is very flexible and compressive among all other cloud services that are available. With this computing system, you receive a virtualized infrastructure of cloud computing you can manage and provision through the cloud provider endpoints. The IaaS provider manages and controls all the physical infrastructures such as data storage space, servers, etc. This way, the customer can customize their virtualized resources according to their requirements. With Infrastructure as a service, you can buy virtual machines and install, organize, and manage any software you want to use. This includes applications such as development tools, business analytics, applications, middleware, and operating systems. Furthermore, you only have to pay for the virtual machine you are using. This will facilitate you in scaling your computing requirements as you need without building any additional capacity. Examples of IaaS are GCE (Google Compute Engine), AWS (Amazon Web Services), EC2, and Microsoft Azure virtual machines.

2.    PaaS

This computing system comes above IaaS in the cloud computing pyramid. Not like IaaS, Platform as a Service more specialized. Instead of providing a virtual machine to you, you get a specific purpose resource in the cloud, which you can put your workload on / or automate your cloud process. In the IaaS model, the customer is responsible for OS-level patching and maintenance. But in the PaaS model, those layers are hidden from the customer, and they can just focus on specific use cases. Microsoft Azure App Services, Apache Stratos, AWS Elastic Beanstalk, and Google App Engine are examples of Platform as a Service.

3.    SaaS

Many people are familiar with this type of cloud computing. SaaS is located at the highest level of the pyramid. Software as a Service is a completely developed software solution that you can instantly use through the internet after purchasing the subscription. Software as a service is responsible for managing data, operating systems, infrastructure, and middleware that is really important for delivering the program and to make sure that wherever and whenever a customer needs access, they always find it available. There is numerous software as service applications that you can directly run on your web browsers without the need for downloading and installing the application. This way, companies can reduce their software management problems for IT teams, and the company can streamline and simplify their operations with multi-cloud and hybrid deployments. The examples of Software as a Service are Google Apps, Salesforce, Cisco WebEx, and Microsoft Office 365.


Cloud computing has changed how companies all over the world operate, something that most people are unable to realize yet. It is essential to understand the types of cloud computing and choose the right one for your business to grow. Cloud computing is increasingly growing, which is opening many new opportunities for businesses looking forward to driving the results of their business and innovating.
