What is Cloud Computing Explain briefly the Advantages?

Introduction of Cloud Computing– Any hosted service that is offered online is referred to as cloud computing. These services frequently consist of servers, databases, software, networks, analytics, and other cloud-operated computer tools.

Transferring to the cloud, Moving through the clouds, In the cloud, Saving and accessing from the cloud-these is the topic of discussion these days. It seems like everything is taking place “in the cloud”. But what precisely is this hazy question mean?

The meaning is that customers of cloud computing services can access files and applications from any location, doing away with the requirement to constantly be close to actual hardware. Your data can be safely kept in the cloud, where you can access apps and services. Three factors make cloud computing important:

  1. You don’t need to make efforts to put any work into managing or keeping it up.
  2. There is no need to be concerned about its capacity running out because it has a practically infinite size.
  3. All you need is a device with an internet connection to access cloud-based applications and services.

This is significant as there is a transition taking place from stationary work to mobile labor. Because of this, the cloud is a great place to host corporate programs like customer relationship management (CRM) software, which users need to be able to access reliably at any time, from any location, using any device.

What is the Use of Cloud Computing

Users of the service don’t need to constantly be close to physical hardware because files and programs saved in the cloud can be accessed from any location. User-made spreadsheets and documents, for instance, used to be saved to a physical hard drive, USB device, or disc. 

The data were entirely unavailable from any computer other than the one they originated from without some sort of hardware component. 

Less people are concerned about damaged hard drives or misplaced or corrupted USB drives these days. Thanks to cloud storage. Due to a network of hosted servers that sends data over the internet, cloud computing makes the papers accessible from anywhere.

Categories of Cloud Computing Service 

The three main types of cloud computing services are- Software as a Service (SaaS) Infrastructure as a Service (IaaS), Platform as a Service (PaaS), 

1- Software-as-a-Service

SaaS is the most popular category of cloud service. It’s something a lot of us utilize every day. Software is made available through an app or web browser thanks to the SaaS approach. Some SaaS applications are free, while many demand a monthly or yearly subscription to keep the service running.

SaaS solutions are quite popular in the corporate world because they don’t need any hardware installation or upkeep. Salesforce, Dropbox, and Google Documents are a few notable examples. 

2- Platform-as-a-Service

PaaS is a cloud environment that supports the creation and deployment of web applications. PaaS helps customers build, test, launch, manage, and update apps over their whole lifecycle in one location.

Moreover, the service offers business intelligence tools, middleware, and development tools. Examples worth mentioning are Google App Engine, AWS Elastic Beanstalk, and Windows Azure.

3- Infrastructure-as-a-Service

IaaS gives consumers access to fundamental components of the computer infrastructure, such as hardware, servers, and data storage, all in the cloud.

Without the requirement for substantial onsite physical infrastructures, IaaS enables organizations to access massive platforms and applications. DigitalOcean, Amazon EC2, and Google Compute Engine are notable IaaS examples.

Advantages of Cloud Computing

A significant change can be seen in that earlier organizations have traditionally viewed IT resources and now it is the time of cloud computing. The following advantages are prevalent among businesses for using cloud computing services:

  1. It is adaptable- Because of the way cloud computing is structured, businesses and their users can access cloud services from any location with an internet connection and scale them up or down as necessary.
  2. It is effective- Organizations don’t have to worry about the underlying infrastructure when developing new applications and quickly putting them into production.
  3. It has tactical utility- Enterprises can get more competitive advantages—and a higher return on investment—than if they had invested in quickly becoming obsolete technologies since cloud providers stay on top of the latest breakthroughs and offer them as services to consumers.
  4. Cost –Cloud computing eliminates the capital expense of buying hardware and software and setting up and running on-site datacentres—the racks of servers, the round-the-clock electricity for power and cooling, and the IT experts for managing the infrastructure. It adds up fast.
  5. Speed- Most cloud computing services are provided self-service and on demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning.
  6. Global scale- The benefits of cloud computing services include the ability to scale elastically. In cloud speak, that means delivering the right amount of IT resources—for example, more or less computing power, storage, and bandwidth—right when they’re needed, and from the right geographic location.
  7. Productivity- Hardware installation, software patching, and other time-consuming IT management tasks are frequently needed for on-site data centers. Several of these duties are no longer necessary thanks to cloud computing, freeing up IT employees’ time to focus on more crucial business objectives.
  8. Performance- The largest cloud computing services are powered by a global network of safe data centers that are routinely updated with the newest models of quick and effective computing gear. In comparison to a single corporate data center, this has several advantages, including lower network latency for applications and greater economies of scale. 
  9. Reliability – Because data can be replicated at numerous redundant sites on the network of the cloud provider, cloud computing makes data backup, disaster recovery, and business continuity simpler and less expensive.

Delivery Models for Cloud Computing:

1- Public Cloud

The majority of cloud computing providers, including Amazon, Microsoft, Apple, and Google, operate public clouds that can be accessed from anywhere with the correct web app and login information.

2- Private Cloud

With the infrastructure requirements (hosting, data storage, IT staff, etc.) met by the businesses or service customers, this model gives the same level of flexibility as the public cloud. 

The private approach also adds a layer of protection due to the limited access and active hosting control.

3- HybridCloud

The public and private types of cloud computing are combined in hybrid cloud computing. The two types of clouds are connected over the internet and can pool resources as needed (for example, if the private cloud reaches storage capacity or becomes corrupted, the public cloud can step in and save the day).


Businesses had to keep all of their data and software on their hard drives and servers before the advent of cloud computing. More storage was required by larger businesses. This method of handling data is not scalable in terms of speed. Your servers would likely crash, for instance, if word of your company spread and you suddenly received a large number of online orders. A successful business requires a lot of work from the IT department. 

The advantages of cloud computing extend beyond enterprises. Our personal lives have also changed as a result of the cloud. Cloud services are used often by many of us. Most likely, we use cloud-hosted applications whether updating our status on social media, binge-watching a new streaming series, or checking our bank accounts. With today’s cloud technology, businesses can scale and react quickly, promote business agility, accelerate innovation, modernize operations, and cut expenses. 

This can not only help businesses get through the current crisis, but it can also result in more robust, long-term growth. Our Future Systems research shows that businesses with a more strategic approach to technology perform better financially. They are outperforming businesses that take longer to adopt and deploy their technology in terms of revenue growth, by more than double. In actuality, 95% of executives have embraced advanced cloud services.
