Hello, friends! Today in this article we will read about what is cloud computing and how cloud computing works. We have written it in a very easy language. Read it completely so that you will understand what is cloud computing. So let's start:
4.Broad Network Access: The Internet is full of cloud computing resources that are very simple to use. To access the resources, a user needs a device and an internet connection.
What is Cloud Computing?
Cloud Computing is a technology that provides various types of services to us using the Internet. This service can be anything, such as computing resources like networking, data storage, servers, databases, and software. In simple language, if you access the data by storing it on cloud-based storage instead of a local storage device, then it will be called cloud computing.
How Cloud Computing works
In Cloud Computing, many servers are connected, that is, computers on which a particular software is installed and used. It can be more than one. It has many programmes. Cloud Computing basically works on Dual Layers technology. There is a separate layer to manage the servers, which is called the back end, and the second layer, which is used by the clients, is called the front end. Similarly, both the back end and the front end together form a server setup for complete cloud computing.
Types of Cloud Computing
Cloud computing is divided into two parts on the basis of different methods;1.cloud-based service
2.on the basis of deployment
1.cloud-based service -
Infrastructure as a Service (IaaS)
IaaS is the most basic type of cloud computing service. It provides basic cloud computing resources such as virtual machines (VMs), storage, and networking. IaaS providers offer customers a self-service interface for provisioning and managing these resources.
IaaS provides an easy way for organizations to get started with cloud computing. However, it also requires the most management from the customer. The customer is responsible for configuring, securing, and maintaining the underlying infrastructure.
Platform as a Service (PaaS)
PaaS is a cloud computing service that provides a platform for developing, testing, and deploying applications. PaaS providers offer customers a self-service interface for provisioning and managing these resources.
PaaS is a good option for organizations that want to focus on developing applications without worrying about the underlying infrastructure. However, PaaS can be more expensive than IaaS and may not offer as much flexibility.
Software as a Service (SaaS)
SaaS is a cloud computing service that provides a software application that can be accessed over the internet. SaaS providers offer customers a self-service interface for provisioning and managing these resources.READ MORE - What is Swift Code and how do I find Swift Code?
2.Its types based on Cloud Deployment:
Public Cloud
SaaS services come under the public cloud, whose deployment is global. These services are available to all users. Users can access the services through the Internet. In this, the services are sometimes free, and many times you will have to pay according to the amount you use them. Amazon Web Services (AWS), Microsoft (Azure), are all examples of public cloud services. However, despite its high reliability, low cost, zero maintenance, and on-demand scalability, it still carries a high security risk. That is, it is not suitable for critical activities.
Private Cloud
This type of cloud computing is understood by the name itself to mean that it is not for public use. Rather like Google Drive, which is an example of a private cloud whose access is possible only through an email ID or any large company or organisation that has its own If you want to build and manage a data centre for yourself, you can use private cloud services. Under this, companies get more improvements in high security, customization, scalability, and flexibility. But it is more expensive than the public cloud. which is not possible for the average man.Hybrid Cloud
In this type of cloud computing technology, public and private clouds are combined. Under this, you can use the cloud according to your needs. That is, you can keep the critical application in the private cloud and the secondary application in the public cloud. The use of this type of service, if some content on a site is available only to registered people and some content is for the public, is called "Hybrid Cloud."
Uses of Cloud Computing
We do not know how many times in our lives we use cloud computing technology. Apart from this, from small start-ups to global corporations, from government agencies to non-profit organizations, we are using cloud computing for one reason or the other. Below are some of the major uses described in detail.File storage - In general, they use cloud computing to store, manage, and share their files in a secure and remotely hosted system. Which we can use while staying in any corner of the world with the help of the internet. Things like Google Drive or Dropbox are good examples of this.
Website Hosting – For people who want to avoid the hassle of hosting and maintaining a website, cloud-based web hosting is a great option for them. in which cloud hosting providers, apart from hosting your website, also provide their computing resources. It also gives security to your website and also takes responsibility for its maintenance.
Cloud database - In contrast, a cloud database is a great option. Every business needs a database. But for this, you will have to spend a lot of money, and at the same time, you will also need an expert. The cloud service provider will not only provide you with support but will also take care of the maintenance and operation of the database.
Backup And Recovery – With cloud-based backup, you can easily back up your data. It is also easy to recover data in this way. While even today, many businesses and organisations take backup of their data manually on a storage device, it is not effective. You do not need to be concerned about their safety.
Big data analytics - A large amount of data is referred to as "big data." Simply put, no conventional data management solution can effectively store or process this kind of data since it is so massive and complex. Such data can be analysed and stored with the aid of cloud computing.
Test and Development – The testing and development of any software and network are two other areas where cloud computing is beneficial. Cloud services make it easier to determine whether your software is operating correctly and whether it has any problems.
Examples of cloud computing:
1.youtube / Google - Just as YouTube is a popular video sharing platform, in which millions of videos are uploaded every second, there are many websites present on Google, in which millions of types of files are uploaded. Cloud computing technology is used to store all these videos or any type of file.
2.Facebook- Like you know, there are millions of users on Facebook, not billions, in which there are profiles of every user and data of every user, which Facebook also uses cloud computing to store.
3.Email- As you know, all the companies that provide email services, such as Google, Yahoo, and other types of online storage services, also use cloud computing.
Characteristics of Cloud Computing
Some of the features of cloud computing are as follows:
1.Elasticity: Companies can easily enlarge resources to increase their capabilities. If not necessary, then hey can also be reduced. Overall, cloud computing has the ability to organize resources.
2.Resource Accessibility: Cloud computing is designed to support a large number of users. In other words, all users can access the resources. This is all accomplished using the multi-tenant model. Users can change both real and virtual resources based on their needs. Due to the fact that resources are gathered to serve numerous users, we sometimes refer to this as "resource pooling."
3.Easy Maintenance and Low Downtime: Server maintenance is very easy. Server downtime is also very low. In some cases, the downtime is negligible. The reason for this is to update cloud computing frequently, due to which the old shortcomings are corrected.
5.On-Demand Self-Service: The user can use computing resources as per his requirements. If it needs instance resources like storage space, a database, a virtual machine, etc., he can use them without requesting from the service provider.
6.Pay as you go: The user has to pay only when the resources are used. That is, there is no extra charge.
Advantages of Cloud Computing
- Large storage: In this, your data is saved on the entire cloud. With this, you can increase your storage as much as you want, according to your needs.
- Ease of access to data: The main benefit of storing data in the cloud is that you can access it from anywhere.
- Large processing power: You don't have to be concerned about processing power in cloud computing because you can purchase as much as you want.
- Less price: In cloud computing, you can take as much storage as you want, as if you want 10GB of storage, then you do not need to take 500GB of HDD. In this case, you will have only 10GB of money, which will also be cheap for you as you need more storage. If so, you can take more.
Cloud computing disadvantages
- The Internet is very important for cloud computing. This has both positive and negative effects on a company. Your business pauses for the period when the cloud service provider's Internet connectivity is disconnected.
- It is unfair to completely entrust the privacy and security of your essential data to a cloud service provider. This is why it is important to choose a reputable service provider.
- There is always a possibility of a cyber attack on the internet as it is not completely secure. That's why you should always be alert.
- The structure of cloud storage systems makes it difficult to manage data there. Therefore, it is a bit challenging to fit into your system.
