Evolution of Cloud Computing

The concept of cloud computing is to rent computer resources. This concept was initially proposed in the 1950's.
Five innovations were crucial in transforming cloud computing into what it is today.
Distributed systems and its peripherals, virtualization, web 2.0, service orientation, and utility computing are all examples of this.

Evolution of Cloud Computing

Distributed Systems and its peripherals:

A distributed system is made up of numerous separate systems that seem to users as a single entity.
The goal of distributed systems is to share resources while still making effective and efficient use of them.
Scalability, concurrency, continuous availability, heterogeneity, and failure independence are all properties of distributed systems.
The fundamental issue with this system was that all of the systems had to be present at the same time and in the same place.
As a result of distributed computing's solution to this challenge, three new forms of computing emerged: mainframe computing, cluster computing, and grid computing.

Cluster computing:-

Cluster computing began in early 1980 as a better solution to the mainframe computer.
Each machine in the cluster was connected to the others via a high-bandwidth network.
These were far less expensive than mainframe systems. These were also capable of doing complex calculations.
As a result, the cost issue was resolved to some extent, but the issue of geographical constraints remained.
Grid computing was presented as a solution to this problem.

Grid computing:-

Grid computing was first presented in the 1990s.
Grid computing is described as a group of computers working to complete a task that would be impossible for a single machine to complete.
To act as a virtual supercomputer, all machines on that network use the same protocol.
Although it solved some problems, as the distance between the nodes increased, new problems emerged.
The main issue that was experienced was a lack of high-bandwidth connectivity, as well as other network-related problems.
As a result, cloud computing is frequently referred to as "grid computing's successor."

Virtualization:-

It was first presented around 40 years ago.
It's the technique of establishing a virtual layer on top of hardware that allows the user to run several tasks on the same device at the same time.
It's a vital component of cloud computing. One of the most prevalent types of virtualization is hardware virtualization.

Web 2.0:-

It's the mechanism by which cloud computing services communicate with their users. We now have interactive and dynamic websites thanks to Web 2.0.
It also adds to the flexibility of web pages. Google Maps, Facebook, Twitter, and another web 2.0 applications are popular examples.
Without a doubt, social media is only available because of this technology. In 2004, it became extremely popular.

Service orientation:-

It serves as a cloud computing reference model. It supports applications that are low-cost, flexible, and upgradeable.
In this computer model, two significant principles were introduced.
Quality of Service (QoS), which includes the SLA (Service Level Agreement), and Software as a Service were the topics (SaaS).

Utility computing:-

It is a cloud platform that specifies high availability strategies for pay-per-use services such as computation, as well as other significant services such as storage, infrastructure, and so on.
