Cloud Computing Tutorial For Beginners: Examples, Types, & Services

The cloud computing tutorial for beginners will help you learn cloud computing concepts, like multiple service models and deployment models, their types, advantages, and architecture.

Cloud computing touches every part of the business world, offering advantages in sharing, storage, flexibility, and maintenance of data. It is like a standard internet connection or a virtual network that provides access to cloud-based services and applications anywhere, anytime. 

Over the past few years, many organizations have shifted from on-premises to the cloud as it provides cost-effectiveness, flexibility, and security to manage their IT operations. This cloud computing tutorial is designed for beginners and professionals to help them learn the basic and advanced concepts of cloud computing in detail. 

What is Cloud Computing with Example? 

Cloud computing enables you to store and access data and computing services over the Internet. It doesn’t store any data on users’ personal computers. You can think of cloud computing as the on-demand availability of computer services, including networking, databases, servers, storage, etc., or a technology that uses remote servers on the Internet to store data.

Some popular cloud computing examples include Google Drive, Amazon Web Services S3, Google Drive, etc. 

Cloud Computing Architecture 

The cloud computing architecture is categorized into two parts: front-end and back-end. While the front end consists of applications and interfaces required for cloud-based service, the back end monitors programs that run front-end applications. 

Below is the diagrammatic representation of cloud computing architecture.

Benefits of Cloud Computing

Cloud computing helps businesses in more ways than one can imagine. Let us understand the benefits of cloud computing below. 

  • Easy to back up and restore data in the cloud. 
  • Shared storage enables groups of people to share information in the cloud. 
  • Allows you to quickly and easily access the stored information anywhere, anytime, using the Internet connection. 
  • Reduces software and hardware maintenance costs. 
  • Huge storage capacity to store important data like images, audio, videos, and documents. 
  • Cost-effective nature due to the pay-per-user pricing model. 
  • Robust security measures and real-time fraud detection ability to keep clients’ data protected from unauthorized access.

4 Types of Cloud Computing 

Cloud computing is a virtualization-based technology. It enables organizations to store and access data in virtual data centers and remote servers. The four main types of cloud computing include: 

Private Cloud 

Also known as internal cloud or corporate cloud, the private cloud is used by companies to develop and manage data centers internally or by third parties. You can deploy private clouds using open-source tools, including OpenStack and Eucalyptus. 

Public Cloud 

The public cloud is open to all, where users can store and access data over the Internet. The computing resources on the public cloud are managed and run by the cloud service provider (CSP) and utilize the pay-per-usage method. Examples of public cloud include EC2, IBM SmartCloud Enterprise, Google App Engine, etc. 

Hybrid Cloud 

A hybrid cloud combines private and public models, making it partially secure. The applications you run on the public cloud can be accessed by anyone. Alternatively, the private cloud applications can be solely accessed by the organization’s users. 

Community Cloud 

As the name defines, the community cloud allows services and systems to be accessed by a group of organizations to share information. Multiple organizations, a third party, or a combination of them can own, operate, or manage community clouds.

Cloud Computing Services 

Next, in this cloud computing tutorial for beginners in easy language, let us understand which three cloud computing services are available for users. 

IaaS Known as Infrastructure as a Service, IaaS helps companies to scale their computing resources up and down without spending on physical expenditure. Some examples of IaaS include AWS EC2, Google Compute Engine (GCE), etc. 
PaaS The Platform as a Service enables organizations with cloud-based platforms to build, deploy, and manage applications. In addition, the service model allows developers to focus on written code without modifying the underlying architecture. Examples include OpenShift, Azure, etc. 
SaaS Instead of installing and running applications, you can run SaaS applications through the web browser. Some examples of SaaS applications include Slack, Google Apps, Salesforce, Dropbox, etc. 

Choosing the best cloud provider, from AWS, Microsoft Azure, or GCP, can be a hassle, especially if you are moving from on-premises to the cloud for the first time. That said, it’s wise to contact the experts for cloud deployment services and to prepare a robust cloud migration strategy. 

Inferenz has a team of data and cloud migration experts who can help you decide which platform to choose. The team will analyze your business requirements and objectives to understand which cloud platform will meet your needs. 

Applications of Cloud Computing 

Now that we have covered all the essential details in this cloud computing tutorial for beginners and professionals, here are its few main applications. 

  • Cloud computing provides timely and cost-effective disaster recovery plans to help organizations with fast and speedy data recovery. 
  • You can create a scalable and flexible testing environment that saves time and manpower. 
  • With the help of a web-enabled interface, you can store files online and access them anywhere. 

Future of Cloud Computing in 2023 & Beyond 

Many innovations and technologies are being created to expand the potential of cloud computing. Gartner analysts said that 85% of companies will embrace a cloud-first principle by 2025, with 95% of the new digital workload deployed on cloud-native platforms. That said, cloud computing will be a must-have tool for enterprises and organizations in 2023 and beyond. 

SMEs and large enterprises will focus on storing applications on the cloud instead of physical hardware owing to the benefits of cloud computing.
