Today, wherever we go, people talk about cloud computing. Cloud computing has gained a top position in this growing technology and promoted information technology as before. Cloud computing has become an ideal way to provide enterprise applications and solutions. Well, what is this cloud computing? One expert's reply is "it's just a comparison of the Internet that provides better data security and flexibility". It creates a bridge between employees and work for small and large industries for business efficiency.

What Is Cloud Computing?

Cloud Computing can be defined as delivering several services for small- and large-scale businesses over the internet. The major services include data storage, server, database, software, and networking.

This reduces the burden of the company to manage physical servers themselves or run software applications on their own machines. The users of the cloud can access files and applications from any device and from anywhere just need an internet connection to work. We can say that it works similarly to email providers like Gmail and data storage like google drive or drop box.

How does cloud computing work?

Cloud computing works on three components that are frontend, backend and network. Cloud computing is an application-based software that stores data on a server that can be accessed from the network.

Frontend – Frontend refers to a user or client computer that can access data stored in the cloud using network or cloud computing software.

Backend – The backend here refers to a computer, server, operating system, and storage device where data is stored. These backend servers are performing responsibilities to securely store data and information. This works when the user runs an action or command on the server and the user receives a response.

Network – The network follows a set of protocol rules. This software uses middleware to ensure seamless connectivity between devices / computers connected through cloud computing.

Types of cloud deployments?

Today many companies are involved in providing cloud computing services to the user. They are well-equipped in terms of security, providing backup, maintaining high demand, etc. in the contract of deployment model, which defines how services are provided from the cloud. There is a separate development model such as:

Private Cloud: A private cloud server is used for a single organization. It provides more security features against unauthorized person attacks.

Public Cloud: A public cloud server is used for public users. Files are available on server and distributed to user in term of licensing policy such as pay per user.

Hybrid Cloud: A hybrid cloud deployments combine public and private cloud. A hybrid cloud is ideal for scalability, flexibility, and security.

Cloud Computing Benefits

Cost effective: For using cloud computing you don’t have to spend more amount on purchasing and maintaining equipment. Here you only need to purchase one cloud service that has the ability to hold maximum applications.

Data Security: This is the most prominent aspect where every business is looking for. The cloud provides many advanced security features that guarantee that data is stored and handled securely. Cloud storage providers provide baseline protection for their platforms and the data they process, such as authentication, access control, and encryption.

Disaster recovery and backup: Cloud computing allows an enhancement to back up your data at the time of any disaster. Data on the cloud also allows you to back up at the time of your device lost or damage.

Mobility: Cloud computing provides you with the ability to manage and control your data from your mobile phone, tablet, etc., employees with busy schedules, or who live far away from the corporate office, use this feature to keep up to date with customers instantly.

5 Challenges of Cloud Computing

Migrations of applications:

The migration of applications is one of the significant problems facing the company today. Although moving a new application from your local to a server is a straightforward process but when it comes to moving an existing application into a cloud environment, many cloud challenges arise.

Application Downtime

A downtime situation occurs when working with cloud computing. This is because your cloud provider may face power loss, low internet connectivity, service maintenance etc. For example, suppose you are working on an application on the cloud and a sudden low internet connection power failure will give you trouble working on that application again.

Lacks of customer support

Cloud computing fails to provide proper customer support. In addition, they want their user to rely on FAQs or online help, which can be a difficult task for non-technical individuals.

Security Threat in the Cloud

This is another shortcoming of cloud computing user in security prescriptive. You may find that you have to submit all your sensitive business data to the cloud. But if security fails here, all your personal data may be at risk.

Technical Issues

Cloud technology always suffers from outages and other technical issues. Even, the best cloud service provider companies can face this type of trouble despite maintaining high standards of maintenance.

Final Word

Although cloud computing has a lot of challenges, it is a fact that its demand and usage is still at a high peak. It offers many advantages that can benefit you and your business immediately. However, early development comes with some shortcomings and it will decrease later. Therefore, this technique is here to stay for a long time.
