The cloud is a data sharing software and service which runs on the internet.
IaaS, PaaS and SaaS are the three main types of cloud computing. Let’s break them down in short.
"As-a-service" refers to cloud computing services, and they include infrastructure, platform, and software as well as varying degrees of administration. What distinguishes IaaS from PaaS from SaaS, then?
Being a top SaaS application development firm, we have investigated and compiled comprehensive data regarding every kind of cloud computing model.
You will learn about the distinctions and advantages of the three cloud computing types in this guide. You can use it to build a cloud computing environment that satisfies all of your requirements.
Let’s understand a few Statistics to prove why people are opting to use cloud.
Cloud Adoption: As of the latest reports, 94% of enterprises use some form of cloud service, highlighting the widespread adoption of cloud technologies in the business world.
Market Growth: The global cloud computing market is projected to grow from $445.3 billion in 2021 to $947.3 billion by 2026, demonstrating the rapid expansion and increasing reliance on cloud services across industries.
SaaS Dominance: Software as a Service (SaaS) continues to be the largest segment of the cloud market, claiming a 70% share of the total public cloud market revenue, which underscores its critical role in digital business strategies.
PaaS Development Trends: Approximately 32% of organizations use Platform as a Service (PaaS), with a growing emphasis on containerization and microservices, reflecting evolving development practices and the need for more agile and scalable application development environments.
IaaS Economic Impact: Infrastructure as a Service (IaaS) is projected to reach $201.83 billion by 2027, growing at a CAGR of 23.2%, which reflects its fundamental role in providing scalable and cost-effective infrastructure solutions to businesses.
Now, let's talk about the distinctions.
We’ve covered the 8 Main differences between IaaS, PaaS and SaaS in the below given table:
Factors | IaaS | PaaS | SaaS |
Definition | Users can pay for the services they use with the Infrastructure as a Service (IaaS) cloud application service. Tools for networking, storage, and application development may fall under this category. | Businesses can access web-based hardware and software through Platform as a Service (PaaS), a cloud-based solution. | Software as a Service (SaaS) offers enterprises full software development options and aids in managing their vendors. |
Target Audience | The network designers | The developers | The end users of an application |
Model Type | In order to facilitate storage, network commissioning, and connectivity with the on-premises data center, this model offers the architect virtualization technology, networking resources, and other infrastructure resources. | This concept was created with developers in mind. It offers testing and development environments to developers so they may work on building applications for the cloud. | Cloud providers' service model enables companies to host and distribute their own programs to consumers. |
Technical Expertise | An in-depth understanding of the cloud computing sector is necessary in order to develop virtual servers or deal with on-premises infrastructure. | Developers need to use basic knowledge to set up the cloud computing architecture. | The SaaS providers will handle everything, including setup and delivery.

Security Requirements | To find out how the cloud service provider handles sensitive data, review their policies. | To make sure there are no risks to the data, the developer must implement more protection. | The security guidelines for the physical and virtual servers should be verified by the SaaS provider. |
After examining the distinctions among the three cloud computing service models, let us delve deeper into a detailed discussion of each.
Let’s first begin with SaaS.
Software as a service is an important form of cloud model. A SaaS application is based on a cloud solution and can be used on the web browser of a client. Additionally it doesn’t require any download.
It is a cloud delivery model which is used to help businesses access applications over the Internet. This cloud model enables businesses to access their solution without the need to manage hardware and software.
Various kinds of SaaS applications, would include web apps, on-demand software solutions and a hosted application. The software application in SaaS will be hosted on a cloud service provider chosen by the vendor and can be accessed virtually.
Plans that are optimized in accordance with the specified features exist. In accordance with the cloud model, the user will pay for the plan they have selected and receive the pre-defined features. The seller controls all areas of security, accessibility, and performance; the user is not responsible for meeting these requirements.
Two main categories of SaaS models exist:
Horizontal SaaS applications: It is a horizontal model which is adopted when the SaaS business offers services to a wider range of industries and business types.
For example, you can use Salesforce for diverse industries, businesses and sizes to scale your company's resources and enhance the overall productivity.
Vertical SaaS applications: This SaaS application is intended for a certain business sector. The model's design takes into account the industry's or niche's problems.
There are a number of benefits that companies can leverage by using Software as a Service. Let’s understand the three main benefits.
By using a SaaS model, you can observe three benefits:
No set-up needed: When using a SaaS solution you need not require to download any software as it is a ready-to-use solution.
No maintenance required: When you are using a SaaS solution, the tasks of upgrading, managing and maintaining the solution is taken care of by the cloud service provider.
No Storage space needed: These solutions do not reduce the storage or disk space. You can utilize and access them with ease because they are virtually accessible.
Are there any good examples of software solutions built on SaaS models? Yes, there are quite a lot of models built on a SaaS solution, some of them are mentioned in the below section.
Chargebee: Enhanced billing capabilities are the goal of this SaaS-based recurring billing solution. This utility makes it simple to set up recurring billing.
Dropbox: The main purpose of this technology is to facilitate remote resource collaboration. With this SaaS app, you may exchange files and documents of any size.
HubSpot: This program assists with all the activities and automates the various workflows in marketing, sales, and customer support.
Given how common these instances are in today's world, you may have a good understanding of how SaaS operates after reading the following examples. However, if you are thinking the use the SaaS platform, then it is necessary to know when should you use it
SaaS being a cloud platform is the best choice for startups which don’t have resources or budget to build the application. It is the perfect choice for the companies that are looking to integrate off-the-shelf solutions for their software needs.
For example, if your client requires a live chat solution, they can use SaaS applications to improve conversational marketing.
Now, let us move to the second type of cloud solution which is known as Infrastructure as a Service.
Empower your business with our robust SaaS solutions that eliminate software setup and maintenance hassles. At Acquaint Softtech, our experts harness cutting-edge cloud technology to deliver scalable, secure, and tailored applications that drive growth.
The IaaS cloud computing service offers you with essential components which can help you with tasks like computing, storage, and handling network resources on-demand. It is also known as a pay-as-you-go model.
While using the IaaS model, you can achieve cost savings in maintenance, disaster recovery and other data center costs.
As the costs of hardware and other infrastructure components approach zero, you have greater freedom to grow your network requirements to accommodate evolving business requirements.
The expenses and difficulties associated with maintaining the physical infrastructure for commercial software solutions can be reduced with this cloud approach. When you add resources to your infrastructure, they are handled like services. You are charged for the extra features or services.
Let’s first understand what is IaaS?
IaaS is a computing resource delivery model over the internet in a cloud computing environment. Virtualized computing resources are on the cloud as delivered. It's one of three basic categories of cloud services besides SaaS and PaaS. The IaaS model says that a cloud provider hosts the conventionally infrastructure constituents usually kept in-house within an on-premise data center; it involves servers, storage, networking hardware, and the virtualization or hypervisor layer.
Now, further let us understand the various types of IaaS.
IaaS cloud model has a number of types which cater to various business needs, we’ve explained them in the below section:
Public Cloud IaaS: This is the model in which resources are given to multiple customers through a public internet by the provider; these resources are housed within the provider's data center. Public cloud services are multi-tenant environments where identical physical resources are shared amongst several clients. Examples are Amazon Web Services, providing EC2, Google Compute Engine, and Microsoft Azure.
Private IaaS: In this particular model of a cloud environment, the infrastructure is maintained for a single organization. Private clouds can be hosted both inside and outside the organization. This is often implemented for enhanced security and control over the environment.
Hybrid Cloud IaaS: Hybrid clouds combine the public and the private, bounded by technology that allows sharing of data and applications between them. This model is combined with more flexibility and a variety of options available while deploying data. Businesses can store sensitive data in a private cloud while, at the same time, utilize the computational power from the public cloud on nonsensitive tasks.
Further, let us understand the benefits of IaaS in the following section.
Below we have mentioned all the benefits of using a IaaS cloud solution model
Reduced costs: When you are shifting an on-premise virtual data center, then you would be able to experience a substantial drop in the overhead costs, thus you will only have to pay for the services that you use.
Easy to scale: IaaS is a cloud solution with an easy scalability possible, i.e. using this would make increasing/decreasing of the resources easy with very minimal requirements.
Availability of applications: Since the data centers are virtually set up, the applications are always accessible. The company has a variety of cloud computing options and data centers to select from. They can guarantee reduced latency and improved availability, which can improve customer satisfaction and boost the company's ability to retain customers.
Improve Recovery solutions: With the IaaS cloud model, businesses are able to enhance their disaster recovery solutions in cases of an outage without investing much time or effort in getting the extra tech staff or adding new resources.
Are there any good examples of software solutions built on IaaS models? Yes, there are quite a lot of models built on a IaaS solution, some of them are mentioned in the below section.
The top three instances of infrastructure as a service are listed below.
Amazon Web Services: This cloud service provider, supported by Amazon, can assist with on-demand computation and delivery options. They provide services for recurring billing. Companies are able to control the delivery and storage of content.
Microsoft Azure: This cloud service architecture leverages Microsoft data centers to build, test, and manage applications based on Infrastructure as a Service (IaaS).
Google: With the help of this robust IaaS platform, companies can better manage their enterprise data and increase productivity.It is compatible with Windows, Oracle, and SAP platforms.
After reading the following examples, you should have a solid knowledge of how IaaS functions given how frequently these situations occur in today's society. But, if you're considering using an IaaS platform, you should be aware of when to use it.
The IaaS cloud model has advantages for businesses of all shapes and sizes. Nonetheless, there are a number of circumstances when IaaS can benefit businesses.
In order to scale computing resources quickly.
When it's appropriate to cut back on capital spending.
When greater agility is required.
In order to lessen the workload associated with infrastructure administration.
If you require access to specific resources
Now, let’s move to the last type of Cloud model which is known as PaaS?
Enhance your IT backbone with our robust IaaS solutions that simplify infrastructure management and boost scalability. Acquaint Softtech’s expert team helps you cut costs, improve recovery, and maintain peak performance while scaling resources seamlessly.
A cloud platform called Platform as a Service enables companies to develop unique applications. The tools needed to develop apps and software solutions are given to developers via this model. It does not, however, assist with the software's online delivery.
Now, let us understand what PaaS is.
It is a cloud platform and a deployment environment which offers a huge range of PaaS tools that can help during a software development project. By using PaaS, you can develop anything from a simple application to an advanced AI-based solution with the help of tools.
A PaaS cloud native solution allows organizations to focus on managing and building applications insteading of worrying about its hardware and software infrastructure.
After learning what PaaS is, continue reading to discover the types of platform as a service.
Public PaaS: Public PaaS is hosted in the cloud, but the third-party provider manages the infrastructure service. Users access the platform via the Internet, and the provider manages security, operating systems, server software, and backups. All that comes with the many benefits of scalability and simplicity, as teams don't have to manage hardware or network features. Examples include Google App Engine, Microsoft Azure App Services, and AWS Elastic Beanstalk.
Private PaaS: Private PaaS lives in the private clouds of an organization, and it is maintained on private hardware. The former combines the elasticity and efficiency of traditional PaaS services with the control, security, and customizability found in the private cloud solutions. Normally, private PaaS is utilized by those organizations that have to meet the required strict data security or regulatory compliance necessities or require better control over the environment. This includes VMware Tanzu and Red Hat OpenShift.
Hybrid PaaS: Hybrid PaaS hosts applications in both private and public clouds. This model of deployment brings about the benefit of maintaining the core applications in a private environment while using the power of scalability of the public cloud for applications that do not hold very sensitive information. Provides flexibility with where and how the applications are hosted to help balance cost, performance, and security.
Communication Platform as a Service (CPaaS): CPaaS is a cloud-based platform that enables companies to add real-time communication features to any application without building backend infrastructure and interfaces. Typical services include voice, video, and messaging integrated via APIs. Examples are Twilio, Nexmo, and Plivo.
Open PaaS: Open PaaS does not tie the customer to any specific cloud provider's set of platform services. It can run on any infrastructure, whether in the cloud or on-premise. Besides, it supports multiple frameworks and programming languages. It is such flexibility that appeals to developers who are in need of a solution that is portable and interoperable. One example of open PaaS is Cloud Foundry.
Software Developers Kit as a Service: SDKs as a Service provide a suite of tools to enable developers to build applications specific to one platform, say, a mobile operating system. This could include libraries and sample code, debugging and testing services, and APIs. It's about putting all the necessary tools required for building an app into one easy and accessible solution.
Further, let us understand the benefits of PaaS in the following section.
Faster development: PaaS tools need a minimal to zero technical knowledge for setup and use. Any developer or an in-house team can easily get started with these tools.
In-built software components: There are various software components which help developers with application development, which includes aspects like workflow, service-related features and security which can enable quicker releases.
Less resourced required: This cloud model enables developers to include new functions and capability without the need of hiring remote developers to fill the skill scarcity gaps.
Easy collaboration: The PaaS cloud delivery model enables the teams to collaborate and work together on app development without being in the same room or country by enhancing remote contributions.
Ever notice that one of the best PaaS examples is Google App Engine? To learn more about Google App Engine and other PaaS examples, continue reading.
We’ve mentioned four best examples of PaaS model below:
Google App Engine: In Google's cloud-based data centers, you may host, develop, and test software apps for mobile and the web.
Heroku: Heroku includes all the tools required to create, oversee, and maintain mobile and online applications that are focused on the needs of the user. It helps developers and speeds up app development.
Apprenda: A fantastic PaaS platform that facilitates communication between companies and developers to create outstanding mobile applications. It facilitates app deployment as well.
Kinsta: Enhancing databases, apps, and other hosting solutions, Kinsta is an all-in-one PaaS cloud model. By utilizing the resources at their disposal, businesses may quickly develop and implement their apps.
Because these scenarios arise often in modern culture, you ought to have a firm understanding of how Platform-as-a-Service operates after reading these examples. However, you should know when to employ a PaaS platform if you're thinking about adopting one.
A great delivery model to utilize when multiple developers are working together to create and test a software application is platform as a service. You can use this to create a unique SaaS application. PaaS can be used for networking, storage, and virtual data center functions if you don't want to use the tools. It can assist in using a third-party cloud to host your application.
