What is cloud computing?

What is cloud computing?


loud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).


Nowadays, everyone seems to be discussing about “What is Cloud Computing”. We are seeing technology shifting to the cloud more and more these days. People have moved from traditional storage software to the Internet progressively over the past 10 years. But what is it?


Cloud computing is providing different facilities and amenities like databases, servers, storage, applications, etc., through the Internet. Instead of storing data in local storage on a hard drive, cloud computing helps us in storing and saving data on a remote database. Given that the device we are using has access to the internet, it will have access to the data as well.

Basically, cloud computing is somewhat outsourcing computer programs. These computer programs are hosted by an external party and are located in the cloud. Because of this, the users have no worries about storage and power and can be at ease where their data is concerned.


Nowadays, many people are opting for cloud computing for a variety of reasons, including increased productivity, better monetary value, time and speed efficiency, security and performance.


Understanding Cloud Computing
Traditional applications were always complex and expensive because the number of hardware and software required to run these applications was intimidating. We needed to install and configure, run and test, secure and maintain these huge applications. Cloud computing helped to eliminate the problems that came with storing one’s own data by reducing the headache of managing the software and hardware. We could pay for storing the data remotely to vendors, who would charge us only on a need basis, making it easy for scaling upwards or downwards.


Cloud computing is so named because the information and data that we are trying to access are discovered remotely in the cloud, which is nothing but virtual space. Cloud users can store files, data, and applications on remote servers and access this data with the help of the Internet. This helps in a way that the user doesn’t have to be in a precise location to acquire access to the data and can retrieve the data from anywhere. Cloud computing reduces the processing involved with the huge amount of data and gets the computer to do all that work.


We have public and private services in Cloud computing. Public cloud services are offered for a charge over the Internet, whereas private cloud services are offered only to a particular set of people. We also have a third option known as a hybrid option that combines elements from both the services.

We have various functions that can be achieved with the help of cloud computing services, like:

  • Email
  • Storage, backup, and data recovery
  • Scrutinizing data
  • Building and testing apps
  • Providing software on demand
  • Audio and video streaming
  • Working of cloud computing

Cloud computing makes it easy to use servers, databases, storage and a wide-ranging set of application facilities over the Internet. A cloud platform possesses and maintains the hardware connected to the network essential for these services while we use whatever we need with the help of a web application. This application is usually a user-friendly dashboard that helps the users to supervise their accounts.

Who is using cloud computing?
Organizations of every type, size, and industry are using the cloud for a wide variety of use cases, such as data backup, disaster recovery, email, virtual desktops, software development and testing, big data analytics, and customer-facing web applications. For example, healthcare companies are using the cloud to develop more personalized treatments for patients. Financial services companies are using the cloud to power real-time fraud detection and prevention. And video game makers are using the cloud to deliver online games to millions of players around the world.

Cloud computing benefits abound as more and more companies utilize cloud applications. Perks like effective collaboration and content sharing are some of the reasons why cloud computing is so attractive.

According to Salesforce, there are several advantages to embracing cloud computing. In just one instance, 94% of businesses saw an improvement in overall data security after migrating to the cloud. Another 91% claimed that government compliance was easier to attain with cloud computing.

Flexibility is another significant benefit of cloud computing. As a third-party organization handles IT infrastructure and data hosting, as a company, our business leaders can focus on providing good customer experience and achieving other goals.

Other benefits to cloud tools include access to up-to-date software, enhanced security, data portability for users and cost-effectiveness.

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 and 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.

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 capital 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 the 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.


Types of cloud computing

The three main types of cloud computing include Infrastructure as a Service, Platform as a Service, and Software as a Service. Each type of cloud computing provides different levels of control, flexibility, and management so that you can select the right set of services for your needs.


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 software.
