Cloud computing: history, benefits and training

cloud computing

Cloud Computing is the way computing services are delivered over the Internet. These computing services include storage, servers, databases, software, analytics, and more. Cloud Computing is an information technology paradigm that allows us to access shared computing resources with minimal management effort. With the help of Cloud Computing, we can use computing resources online through the Internet without investing money in building and maintaining a computing infrastructure. In this way, Cloud Computing enables organizations to focus on their core business instead of struggling to build a high-performance computing infrastructure. Another great advantage of Cloud Computing is that it offers a "pay-as-you-go" or "pay-per-use" model, meaning that you only pay for the resources you have used. It reduces your operating costs.

History

The term Cloud Computing first appeared in 1996 (mentioned in an internal Compaq document). Later, the term gained popularity in 2006 when amazon.com released its Elastic Cloud Computing platform "Amazon web services". In early 1993, the term cloud was used to refer to a network of distributed computers.

Advantages

The rise of Cloud Computing has brought a number of benefits to organizations and individuals, including the ability to access any software or resource on any device without having to install it on your local device. Here are some of the main benefits.

1. Flexibility
   One of the major advantages is scalability. As your business needs grow, it's easy to scale your cloud resources from remote servers. Therefore, Cloud Computing is ideal for companies with a growing demand for resources.


2. Cost
   It reduces the capital costs of building and maintaining computing infrastructure. You can easily access any resource through the cloud without having to run on-premises data centers and hire TI experts to manage this large infrastructure.


3. productivity
   Traditional on-site computing infrastructure requires a lot of hardware setup and time-consuming infrastructure management. It increases your productivity by removing these time consuming tasks and allows organizations to focus on their core business.


4. Performance
   Most of the cloud service providers regularly upgrade the services to the latest generation to improve performance and provide fast and efficient computing services. This increases the productivity of organizations that share their resources.


5. Pay per use
   Another great advantage is that the providers offer you "pay-as-you-go" based services, which means you only have to pay for the services you use. This reduces the management costs of organizations.


6. Security
   It gives you better security as the data is stored in the cloud, you can access your data and resources from anywhere even if you lost your laptop. And you can also easily remove your personal data from your lost machine so no one can access it.


7. Work anywhere
   If you have an internet connection and a laptop in your hand, you can work from anywhere by accessing cloud resources over the internet. Cloud services also offer mobile applications so that you can also access resources on your smartphone.

Type of services

In general, IT services fall into three categories, namely IaaS (infrastructure as a service), PaaS (platform as a service), and SaaS (Software as a service). These three Cloud Computing services are also referred to as the Cloud Computing stack because they form a stack as they stack on top of each other. Here is an overview of these three services.

Infrastructure as a Service (IaaS)

Infrastructure as a Service is one of the most important categories of services. It provides virtualized computing resources such as virtual machines, storage, networking, and operating systems to individuals or an organization from a cloud provider.

Platform as a Service (PaaS)

Platform as a Service is a service category that provides developers with the platform to build applications and services over the Internet. PaaS provides the on-demand development environment for developing, testing and managing software applications.

Software as a Service (SaaS)

Software as a service is a category of its services that provides on-demand software applications over the Internet. Cloud providers host and manage software applications and enable their users to connect to and access the application over the internet.
