What is Cloud Computing?

Cloud computing is the delivery of computing services over the internet to offer faster innovation, flexible resources, and economies of scale. instead of buying, owning, and maintaining physical data centers and servers you can access them through the internet.  However, these services are servers, storage, database, networking, software, and intelligence. Traditionally, you just pay for the service you use. this helps you to reduce operating costs and run your infrastructure more efficiently.

Benefits of Cloud computing

Scalability

The scalability word shows the capacity that can be changed in size or scale. However, in cloud computing scalability means increasing or decreasing IT resources according to need or to meet changing demands. Data storage and networking can be scaled in the existing cloud computing infrastructure. Scaling can be done very quickly and easily with a little bit or no disruption.

Scalability increases the speed of working by providing all accessible and available resources without delay. Indeed, this timely availability of resources helps the team to focus on their target. It also saves costs from disaster recovery by eliminating the need for a physical secondary data center.

Productivity

Cloud computing has increased productivity in many ways for any business or small organization. first of all, if you are a cloud user then you don’t have to worry about its security  Moreover, you don’t have to worry about the updates that are available for the software o any IT resources that you are using cloud responsibility to upgrade resources time to time. Consequently, you get that time for your work and maintenance of servers.

Secondly, remote access to information and data to employees who can access it from anywhere in the world. because sometimes holidays or days of an employee affect your organization’s productivity. By using the cloud, now it’s possible to access data to work on it.

Thirdly, and most importantly it gives freedom to an organization from hardware availability. Because if you are using cloud computing then you can use any IT resource which is available on the internet.

Security

In today’s era, the security of data and information is very critical and not easy. In organizations, data leakage, hardware theft, and unauthorized access to sensitive information are at their peak.  But in cloud computing, there are some rules, policies, and regulations to ensure the data security and privacy of individuals.

These policies are used to filter authentication for data access. Moreover, it protects software and servers from malware and other hacker attacks. To solve all these problems there is a special team whose duty is to protect cloud-based services from damage.

As cloud computing has a name in the computing and business industry. So to keep its integrity cloud security implements needed rules and technologies to ensure data security.

Cost

Cloud computing has now become a widespread application with its IT resources. Its main reason due to its benefits. In all of these, cost reduction is most important which is a huge benefit to users. It reduces costs in many ways.

First of all, hardware cost reduction that is an essential part of any organization. For instance, if your business is increasing rapidly then investing in hardware will be not good for company revenue.

Secondly, maintenance of data and software cost reduction. Maintaining the software that you are using is very important and this is a very costly thing. But in cloud-based systems, this cost is not your business. You just have to use the service and pay for this according to plan.

Thirdly, the cost to secure your data and hardware from any kind of theft. You don’t have to keep a person or any team to secure your data all these things are done by cloud security.

Fourthly, the cost of adoption according to existing systems or updates. To upgrade your existing system is a very expensive and important thing. This cost is also covered by cloud computing, not yours.

Performance

Cloud computing increases performance by making multiple copies of data. So that data can be accessed by all the employees all the time simultaneously. As in cloud computing updates and maintenance of software are all done in time, this does not delay any kind of processing. And that gives a booster to its performance. There are different ways to improve the performance of computing. Like using the right instance, connect directly to the network, automate everything use caches.

Moreover, backup of data is always available. In case of destruction, that backup helps in working with no delay.

Speed

Cloud computing increases the speed of working. For this, you need a strong internet connection. the most important thing is that you can work remotely at any time. Because all the required resources and services are available with one click. You don’t have to waste time on resource allocation you just have to pay for this and use it immediately.

Firstly, the availability of resources plays a very important part in the speedy working of the organization. Secondly, automatic scaling and updating also play an important role.

Reliability

Speed, performance, and security all these things make it reliable and trustable. Because it’s a matter of privacy and information that is very valuable. For this, trust is an essential part of the system. All the above-mentioned benefits make this application reliable.

Uses

Due to its benefits cloud computing use is on large scales and broadly.

• File storage
• Back up from disaster
• Data analytics
• Social networking
• Software testing and development
• Collaboration
• Many more

Type

1. Private clouds
2. Public clouds
3. Hybrid clouds
4. Multi clouds

Private clouds

A cloud computing environment in which all the IT resources are dedicated and accessible to one single person. Many companies choose it because the private cloud is an easy way to meet their regulatory compliances requirements. Their workload deal with confidential documents, intellectual property, personal information, medical record, and other sensitive information. For example, HP data center, Microsoft, and Ubuntu.

Public clouds

Public cloud where on-demand computing services are managed by the third-party provider and shared with many other organizations using a public network. Companies use public clouds for a less-sensitive application that does not require frequent access. The public cloud makes computing services available for everyone for purchase. Multiple users share the use of the public cloud. For example, Microsoft Azure.

Hybrid cloud

A hybrid cloud is one in which applications are running in a combination of public and private cloud computing environments. Hybrid cloud approaches are widespread because almost no one relies entirely on the public cloud. This gives greater flexibility and more data deployment options. For example, AWS outposts, Azure Stack, and Azure Arc.

Multi clouds

Multi-Cloud is a model of cloud computing where an organization utilizes a combination of clouds, which can be two or more public clouds, two or more private clouds, or a combination of both public and private clouds. 

In a word, Multi-Cloud is the superset of multiple public cloud, hybrid, on-premises, and edge. A multi-cloud deployment model relies on the use of more than one public cloud service provider for compute or storage resources, independent of the use of other private cloud or on-premises infrastructure. Examples, AWS, Google cloud platform, Microsoft Azure, and IBM.
