Architecture of Cloud Computing Types (IaaS vs SaaS vs PaaS)

Architecture of Cloud Computing – Different Types Explained (IaaS vs SaaS vs PaaS).  To a lot of non technical managers, the word Cloud, its concept of what it is and what it does have always stayed cryptic. That is why executing cloud computing can be relatively challenging for some organizations. Another thing that leads them to escape cloud computing is the use of apps and digital services powered by cloud computing by consumers.

However, when IT managers are aware of its architecture and the needs, it is one step forward in clarifying the competitive advantages they might have after implementing cloud in organizations.

Therefore, in this guide, we have created a detailed overview of what the architecture of cloud computing is and its different components.

What Is Cloud Computing?

Cloud Computing is highly in demand today. It is shaping the organization with the help of its on demand virtualized services and resources. Organizations ranging from small to medium and medium to large have deployed their services to store information and access it from anywhere around the world by just using the Internet.

With the help of these services, every infrastructure experiences some of the essential constraints like transparency, scalability, security, and intelligent monitoring. Moreover, the cloud computing architecture is divided into two parts: frontend and backend.

Frontend cloud computing constitutes client site interfaces and applications that are suitable for cloud based services. It includes hardware and software components like virtualization software, server, data storage, etc. It also includes Graphical User Interface, which is vital for performing the given tasks.

On the other hand, Backend cloud computing provides support required for running and monitoring the programs and applications included in the frontend cloud computing architecture. It is considered the backbone of the entire cloud platform architecture.

Types Of Cloud Computing - IaaS vs PaaS vs SaaS

Cloud Computing Architecture is cloud services, infrastructure, platform, or solutions hosted by third party providers and uses the Internet for accessing it. They comprise three different types of as a services, each facilitating user data flow that ranges from frontend client to the client service provider’s system, i.e., back end. However, they differ in their services.

Infrastructure as a Service (IaaS)

IaaS is a cloud service provider that manages the entire infrastructure, including its server, network, virtualization, and data storage, with the help of an Internet connection. You can access it with the API or dashboard or can rent the infrastructure. You can also manage things like operating systems, apps, and middleware, and the cloud infrastructure takes care of hardware, networking, hard drives, data storage, and servers. It also takes care of outages, repairs, and hardware issues. 


Examples of IaaS are Azure or AWS.

Software as a Service (SaaS)

SaaS is a service that delivers a software application that is managed by cloud service providers. Generally, these are mobile apps or web applications that you can access through a web browser. It takes care of the software updates, bug fixes, and other general software maintenance and connects to the cloud application through a dashboard or API. When you use these services, you also do not have to install apps locally on every individual’s computer. This way, a greater number of groups or teams can easily access this software.


Examples of SaaS are Office 365 and SalesForce

Platform as a Service (PaaS)

PaaS is the hardware and an application software platform provided and managed by an outside cloud service provider. However, you can handle the apps running on top of the platform and the data the app relies on. It is the best software for both developers and programmers as it helps them in developing and managing application building or maintaining infrastructure usually associated with the process.


Examples of PaaS are Microsoft Azure or Google App Engine

Benefits Of Cloud Computing

Cloud Computing provides a wide variety of benefits. Some of them are listed below:

Greater Accessibility

Cloud Computing Architecture provides access to data and digital tools. It enables you to access almost every browser and mobile device. It also boasts a responsive design to boot. Moreover, since this software does not restrict updates or patches, the uptime remains dependably high.

Cost Effective

Implementing the cloud computing architecture in your organization provides your team relief from the heavy workload. Generally, an on premises system requires servers, data centers, and a team of developers to manage and maintain the system. This incurs a lot of costs. But, the software reduces IT costs, thereby freeing up IT teams to innovate instead of fixing bugs and dealing with server issues.

Scalable and Flexible

If you deal with fluctuating bandwidth demand, cloud computing architecture is an ideal solution for you. It helps you in scaling up the cloud capacity by changing the usage plan. Furthermore, it provides a level of flexibility that proves to be highly advantageous for your business.

IoT Ready

When you integrate headless content management, cloud computing architecture embraces the IoT more rapidly and at a very lower cost. Today, everyone has access to smartphone devices. This way, you can easily interact with their consumers or internal staff on any platform.

Encourages Remote Working

The study conducted by Standford states that employees who work from home are 13 percent more productive than the ones who work in the office environment. With the help of cloud computing, employees can work from anywhere around the world and at any time.  For example you can deploy Azure RDS for remote working using Remote Desktop Services.

Components Of Cloud Computing

Cloud Computing Architecture comprises the following significant components:


The hypervisor is a virtual machine monitor that provides you with Virtual Operating Platforms. It enables you to operate guest operating systems in the Cloud. With the help of this component, you can run a separate virtual machine on the back end containing software and hardware. It is mainly used to divide and allocate resources.  An example of a hypervisor is Hyper-V or Vmware.

Management Software

Management Software is responsible for managing and monitoring cloud operations using several strategies beneficial in increasing the performance of the Cloud. It performs the operations like compliance auditing, management of overseeing disaster recovery, and contingency plans.

Deployment Software

Every mandatory installation and configuration required for running a cloud service is stored in Deployment Software. It deploys all three models, including SaaS, PaaS, and IaaS.


The network is used for connecting both the front and the backend as well as allowing users to access cloud resources. With the help of this component, you can connect and customize the route and protocol. Since it is a virtual server, it is hosted on cloud computing platforms. This makes it highly secure, flexible, and cost efficient.

Cloud Server

It is considered a Virtual Server on a cloud computing platform. This server is cost effective, flexible, and highly secure.

Cloud Storage

With cloud storage, you can store and access every bit of data by staying anywhere around the world and just using the Internet. It is highly scalable and can be accessed automatically. You can also modify and retrieve data from cloud storage over the web.

Architecture of Cloud Computing Types (IaaS vs SaaS vs PaaS)

Cloud Computing types (IaaS vs PaaS vs SaaS) enables your organization and other businesses to securely build applications and use cloud services according to their requirement. It is highly flexible in scale. It helps you access data remotely and through the web, collaborate with the team, process data, digital tools, higher security, disaster recovery management, etc., making it a highly preferred and recommended technology among users. Therefore, if you have not implemented cloud computing in your business strategy yet, it is advisable to do it immediately without wasting much of your precious time.
