What is Cloud computing? Advantages, Disadvantages and Future

The future of data processing?

What is the cloud:

“The cloud” refers to servers that are accessible on the internet, and also the software system and databases that run on those servers. Cloud servers are fixed in data centers everywhere on the planet. By victimization cloud computing, users and firms do not have to manage physical servers themselves or run software system applications on their own machines.

What is Cloud Computing:

The cloud allows users to access identical files and applications from virtually any device, as a result of the computing and storage takes place on servers in an exceeding data center, rather than domestically on the user device. This is often why a user can log in to their Facebook or Instagram account on a brand new laptop or phone when their recent phone got damaged or loss and still notice their recent account in situ, with all their photos, videos, and spoken communication history. It works identical method with cloud email suppliers like Gmail or Microsoft workplace 365, and with cloud storage suppliers like Dropbox or Google Drive.

Cloud computing has become one in every of the newer buzzwords in business circles for tiny and medium level businesses. whereas not all little businesses have started exploitation cloud computing, several realize the cloud offers them extra services or cupboard space for his or her comes or files. Especially, those small businesses that cannot afford their own database infrastructure, depend on cloud infrastructure for handling data. Most firms are accessing the cloud to reinforce their ability to share files internally to staff or outwardly to customers; but, there are several smart reasons to feature cloud computing to your company’s resource list if you haven’t already done, therefore.

How cloud computing works:

To know, how cloud computing works, we can divide the process into two categories

  • Front end
  • Back End

The front end is just like a user interface which allows user to access data via any favorite browser, web application, or mobile application. While backend is the main part of this infrastructure which ensures the safe and smooth flow of data across servers and users. This part consists of the central server, computer, databases, and some small servers. The central server follows some rules for seamless connectivity between devices connected via cloud computing called Protocols.

Advantages of Cloud Computing:

There are several advantages of cloud computing in business, education, and other works. Let us discuss some of these

  • Easily Interfacing: Cloud hosting permits firms to retain similar applications and processes while not having to deal with the backend complexities of the server. Readily controllable by the net, a cloud infrastructure may be accessed by enterprises simply and quickly
  • Easy accessibility: Using cloud infrastructure, you can access data everywhere by login to the cloud. This feature increases the productivity and efficiency of data as data is easily accessible everywhere. Easy accessibility of data makes it a good option both for users and firms.
  • Recovery of data: some times your data can be lost due to several reasons. In this case, the cloud provides us the efficient recovery of data. The cloud always keeps a copy of your data and recoverable in case of any loss.
  • Growth Flexibility: Some time your data size increases than the storage you buy on Cloud. For this, the cloud is easily scalable. Therefore, you can scale your data anytime according to your demands.
  • No Physical Storage: As all your data is stored in the cloud, accessible by your login id, so you do not any physical hardware for this purpose.
  • Cost Saving: Cost saving is the biggest good thing about cloud computing. It helps you to save lots of substantial cost of capital because it does not would like any physical hardware investments. In addition, you are doing not would like trained personnel to take care of the hardware. The shopping for and managing of kit is completed by the cloud service supplier.
  • Reliability: It is one of the great edges of cloud computing. As you can easily rely on these services due to the extremely secure and friendly mechanism.
  • Collaboration and strategic Edge: this allows employees all across the world to collaborate with the firm in a convenient and secure way. Moreover, it allows you to access up-to-date software at any time without installation.

Disadvantages of Cloud Computing:

As every application in the world has some advantages and disadvantages at the same time so as to cloud computing. Let us discuss some disadvantage of cloud computing

Security: Security risk is one of the biggest disadvantages of cloud service. By signing to the cloud, you are allowing the third parties to access your sensitive information. However, Cloud services provide many licenses for security purpose but there is always a risk.

Downtime: It is one of the biggest disadvantages of cloud computing. As central server can face many issues such as connectivity or power loss and maintenance etc. which causes downtime to all users.

Bandwidth Issue and Customer Support: Some cloud services provide much less bandwidth to users. If a company accidentally exceeds the limit, the service puts heavy charges on users which is an indication of poor support of these companies. They depend on customers to rely on FAQ which is much tedious for non-technical people.

Connectivity Issue: To access data in the cloud, users must have internet connectivity. Without the internet, there is no alternative to collect data.

Real-time operating system: The systems which require data process in real-time are not recommended to use cloud services as it needs greater time for processing. Furthermore, it also has issues of server down and bandwidth, etc. So, to overcome the situation, a new technique “Edge Computing” is now introduced.

FUTURE OF CLOUD COMPUTING: Today, we will connect everything digitally to Cloud Computing. It provides an entirely new world of jobs, applications, services, and platforms. we will see the long run of Cloud computing as a mix of cloud-based software package products and on-premises cipher which is able to facilitate to make hybrid IT solutions. According to Gartner.com:

“The worldwide public cloud services market is projected to grow 17.5 percent in 2019 to total $214.3 billion, up from $182.4 billion in 2018, according to Gartner, Inc. … The second-highest growth rate of 21.8 percent will be achieved by cloud application infrastructure services or platform as a service (PaaS).”

The changed cloud is ascendable and versatile, which is able to offer security and management over the information center. Due to security, bandwidth, server down, and real-time processing issues, its future is not very bright in applications where real-time processing is required. Nowadays, cloud computing is replaced by a new technology called Edge computing. The main focus of edge computing is to form servers at a local level for real-time processing.
