Cloud Computing

Introduction To Cloud Computing

Cloud Computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet. Large clouds, predominant today, often have functions distributed over multiple locations from central servers. If the connection to the user is relatively close, it may be designated an edge server.

Initiating with an introduction, Cloud Computing refers to the on-demand delivery of computer services, such as servers, databases, storage, networking, and even software, over the Internet with a charge on usage. The origin of cloud computing might not date more than a decade back, but the cloud technology involved has only seen new solutions and benefits to the users.

Shifting the traditional way of thinking of businesses about IT resources, the cloud helps to cut off on capital expenses in acquiring hardware and software, provides increased speed and agility due to availability of new IT resources on a single click, allows easy deploying of applications to multiple locations in the world at a time, and easy data backup with disaster recovery opportunities, making it one of the most popular way of computer-related services pooling.

It has merely been a decade when the first cloud computing service came into existence. But now, a considerable number of organizations, whether big or small, non-profit or government agencies, are making use of cloud technology for different purposes. Let’s have a look at the things you can do with cloud computing:

• Developing new applications and services
• Hosting blogs and websites
• Storage, back up, and recovery of data
• Delivery of software on demand
• Streaming videos and audios as well
• Analysis of data for predictions

The goal of cloud computing is to allow users to take benefit from all of these technologies, without the need for deep knowledge about or expertise with each one of them. The cloud aims to cut costs and helps the users focus on their core business instead of being impeded by IT obstacles. The main enabling technology for cloud computing is virtualization. Virtualization software separates a physical computing device into one or more "virtual" devices, each of which can be easily used and managed to perform computing tasks. With operating system-level virtualization essentially creating a scalable system of multiple independent computing devices, idle computing resources can be allocated and used more efficiently. Virtualization provides the agility required to speed up IT operations and reduces cost by increasing infrastructure utilization. Autonomic computing automates the process through which the user can provision resources on-demand. By minimizing user involvement, automation speeds up the process, reduces labor costs and reduces the possibility of human errors.

Over the past years, cloud technology has improved the manner businesses operate. At present, whether big or small, all companies rely on public cloud platforms for hosting and implementing the applications. And the same trend will be followed in the future. Whether you are a beginner in the cloud computing domain or want to grow your current cloud career, a cloud computing certification will be helpful for you to adopt the latest skills. This will also enable you to contribute to the business of your organization.
