What Is Cloud Computing In Simple Terms?

In recent years, Cloud Computing has enhanced businesses’ and organizations’ ways of storing, accessing, and managing information. Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing.

No more need to buy physical servers when you can access technology services on an as-needed basis from a cloud provider like TRIOTECH SYSTEMS.

Who Uses Cloud Computing Services?

Businesses of every size and type use cloud computing for various reasons, including disaster recovery email, data backup, software development and testing, and big data analysis. Moreover, Cloud computing provides developers access to scalable resources and tools for building, testing, and deploying applications. Examples of cloud computing include some healthcare companies that are using Cloud Computing to enhance personalized treatments for their patients, Google Docs is an example of cloud computing, and video game makers are also using Cloud Computing to deliver online games to millions of users. Consumers use cloud services to store photos, videos, and documents and access applications and services on the go. It provides unending flexibility to its customers as compared to traditional infrastructure.

What Is Cloud Computing Architecture?

Imagine the cloud as a giant digital storage space and toolbox on the internet. It’s like a virtual warehouse where you can store your files, run your software, and do all sorts of cool things without owning any physical equipment.

Now, let’s discover what that virtual Cloud Computing architecture is made of.  The services hosted on a cloud can be divided into infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS). Based on the deployment model, the cloud can also be classified as a public, private, or hybrid.

Moving on, Cloud Computing architecture is divided into two layers: the front-end and back-end. The front-end layer is the one to which the user interacts known as the user interface where they can easily access the data stored on the cloud through computing software.

On the other hand, the back-end layer of Cloud Computing architecture is responsible for managing, processing, and storing data behind the scenes. It comprises physical and virtual servers, computing, and networking services that power the cloud infrastructure. Due to this layer, the cloud applications run smoothly and securely because it ensures tasks such as data storage, networking, and security.

Both layers serve as partners and provide robust and scalable cloud services. The front-end layer focuses on the user interface whereas, the back-end layer handles infrastructure.

4 Types of Cloud Computing Services:

The 4 types of Cloud Computing services are based on deployment and service models which may include:

Based On Deployment:


Private Clouds are operated solely as an isolated cloud environment for a single organization. Unlike public clouds, private clouds are hosted on-premises or by a third-party provider exclusively for one organization. Private clouds are the best option for companies with strict security needs, offering enhanced security, control, and customization options.


Public Clouds are offered to multiple users and organizations who share the same infrastructure hosted by the provider. Public cloud service is provided by third-party providers. Its service is cost-effective and flexible making them ideal for heavy workloads.


Hybrid Cloud Computing combines public and private cloud environments, allowing organizations to leverage both benefits. In a hybrid cloud model, workloads can be deployed across public and private clouds based on security, compliance, performance, and cost, which are why hybrid clouds are considered more flexible mobile solutions.


Multi-cloud computing uses multiple cloud service providers to meet businesses’ desired requirements and needs. Using a multi-cloud strategy, workloads can be distributed across multiple cloud platforms while taking advantage of each unique feature, such as pricing models.

Based On the Service Model:

Infrastructure as a Service (IaaS):

IaaS provides the fundamental building blocks for cloud IT. It generally grants access to networking capabilities, computers (virtual or dedicated hardware), and data storage space. IaaS provides the highest level of flexibility and administrative control.

Platform as a Service (PaaS):

PaaS provides a platform for developers to create, deploy, and manage applications without maintaining underlying infrastructure. PaaS vendors provide development frameworks, databases, and other technologies. This enables developers to focus on developing code and creating creative apps.

Software as a Service (SaaS):

SaaS is the most common type of Cloud Computing. Software applications are delivered over the internet on subscription, removing the need for consumers to install, maintain, or update software on their devices. The provider hosts and manages SaaS applications, including maintenance, updates, and security fixes.


Cloud computing has evolved as a disruptive technology that has changed how organizations and consumers access and use digital resources. The cloud provides flexibility, scalability, and cost-efficiency from infrastructure and platforms to software applications. Whether public, private, hybrid, or multi-cloud, organizations may use Cloud Computing to promote innovation, simplify operations, and meet business objectives in today’s digital world.


What are the advantages of using Cloud Computing?

Scalability, cost-effectiveness, accessibility, reliability, and security are among the primary benefits of Cloud Computing.

How can I choose the right Cloud Service Provider?

Consider the factors of cost, flexibility, and reliability along with your business’s needs and requirements.

Is my data safe in the Cloud?

Security measures are the priority for any Cloud Service Provider so they access controls to protect your data but it’s better to choose a reputable provider and implement additional security as needed.

Can I switch between Cloud Service Providers?

Yes, but it may involve data migration and compatibility issues, so planning and executing the transition carefully is essential.
