What is cloud computing?
Cloud computing signifies the instantaneous procurement of computing resources—whether tangible servers, ethereal virtual machines, expansive data repositories, intricate networking frameworks, development utilities, or software driven by artificial intelligence—all available over the internet with a pricing model contingent on usage.
The paradigm of cloud computing bestows upon its users unprecedented latitude and scalability when juxtaposed with conventional, localized infrastructure.
In the tapestry of our daily existence, cloud computing is an integral thread—whether one is interfacing with cloud-based applications like Google Gmail, indulging in the cinematic offerings of Netflix, or immersing oneself in a video game hosted in the cloud.
In the realm of business, cloud computing has evolved into a cornerstone, supporting enterprises of all magnitudes—from fledgling startups to sprawling global corporations.
Its myriad applications in the corporate landscape include facilitating remote work by rendering data and applications ubiquitously accessible, constructing a framework for fluid omnichannel customer interactions, and supplying the immense computing prowess and ancillary resources requisite for harnessing avant-garde technologies such as generative AI and quantum computing.
What is cloud computing? Benefits of Cloud Computing
Agility
The cloud gives you easy access to a broad range of technologies so that you can innovate faster and build nearly anything that you can imagine.
You can quickly spin up resources as you need them—from infrastructure services, such as compute, storage, and databases, to Internet of Things, machine learning, data lakes, analytics, and much more.
You can deploy technology services in a matter of minutes and get from idea to implementation several orders of magnitude faster than before. This gives you the freedom to experiment, test new ideas to differentiate customer experiences, and transform your business.
Elasticity
With cloud computing, you don’t have to over-provision resources up front to handle peak levels of business activity in the future. Instead, you provision the amount of resources that you actually need. You can scale these resources up or down to instantly grow and shrink capacity as your business needs change.
Cost savings
The cloud allows you to trade fixed expenses (such as data centers and physical servers) for variable expenses and only pay for IT as you consume it. Plus, the variable expenses are much lower than what you would pay to do it yourself because of economies of scale.
Deploy globally in minutes
With the cloud, you can expand to new geographic regions and deploy globally in minutes. For example, AWS has infrastructure all over the world, so you can deploy your application in multiple physical locations with just a few clicks. Putting applications in closer proximity to end users reduces latency and improves their experience.
What is cloud computing? Types
Infrastructure as a Service (IaaS)
IaaS contains the basic building blocks for cloud IT. It typically provides access to networking features, computers (virtual or on dedicated hardware), and data storage space. IaaS gives you the highest level of flexibility and management control over your IT resources.
It is most similar to the existing IT resources with which many IT departments and developers are familiar.
Platform as a Service (PaaS)
PaaS removes the need for you to manage underlying infrastructure (usually hardware and operating systems) and allows you to focus on the deployment and management of your applications.
This helps you be more efficient, as you don’t need to worry about resource procurement, capacity planning, software maintenance, patching, or any of the other undifferentiated heavy lifting involved in running your application.
Software as a Service (SaaS)
SaaS provides you with a complete product that is run and managed by the service provider. In most cases, people referring to SaaS are referring to end-user applications (such as web-based email).
With a SaaS offering, you don’t have to think about how the service is maintained or how the underlying infrastructure is managed. You only need to think about how you will use that particular piece of software.

What is cloud computing? FAQs
What is cloud computing in simple terms?
Cloud computing is a way to use computers and data storage over the internet instead of on your own computer. It allows you to access and use programs, services, and files from anywhere, as long as you have an internet connection.
What is PaaS in cloud computing?
PaaS stands for platform as a service. It’s a cloud computing service that provides a platform allowing developers to build, run, and manage applications without worrying about the underlying infrastructure like servers, storage, or networks.
What is a virtual machine in cloud computing?
A virtual machine (VM) in cloud computing is like a computer within a computer. It allows you to run an operating system and applications in a separate, virtualized environment within your physical computer, making it easier to manage multiple tasks or applications independently.
What are the cons of cloud computing?
Some cons of cloud computing include dependency on internet connectivity, potential security risks, possible downtime of cloud services, limited control over the infrastructure, and ongoing costs, which can be higher in the long term.
What do you mean by cloud computing?
Cloud computing refers to the delivery of various services like storage, processing power, and software over the internet (“the cloud”). Instead of having local servers or personal devices handle tasks, cloud computing allows these to be managed remotely by a cloud service provider.
Which is a fundamental attribute of cloud computing?
One fundamental attribute of cloud computing is scalability. This means you can easily increase or decrease your computing resources based on your needs without investing in new hardware.
What is a data center in cloud computing?
A data center in cloud computing is a large group of physical servers and networking equipment used by cloud providers to store, manage, and process data. These centers are the backbone of cloud services, ensuring data is available and secure
What are the security risks of cloud computing?
The security risks of cloud computing include data breaches, loss of control over sensitive data, potential service outages, insider threats, and issues with compliance and data sovereignty.
How does cloud computing work?
Cloud computing works by using a network of remote servers hosted on the internet to store, manage, and process data, rather than relying on local servers or personal computers. Users access these resources over the internet, allowing them to use powerful computing and storage without needing to own the physical infrastructure.
