Back to Basics: Cloud Computing

How New-Age applications are getting benefitted

Cloud is one of the buzzwords in the industry, thanks to the revolution on the Internet and advanced technology. With the availability of resources, so many ideas went into the phase of Implementation. So many applications like Netflix, Whatsapp, PhonePe have emerged by using the cloud as a resource pool. Now let’s try to understand what is cloud…

What is Cloud?

“Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services)

In simple words, providing a pool of resources to satisfy the needs, requirements of the user

How did it started && How does it work?

Traditionally, organizations have their own infrastructure with their own maintenance. Organizations used to add more pools when there is huge demand and once the demand is over, resources will be left idle which resulted in the wastage of resources. So that’s how the cloud concept evolved.

With the introduction of the cloud model, Infra architects can able to plan the architecture as per demands without wasting the resources by pooling the Hardware resources and connecting them to provide the services.

As per NIST 800–145, it works in the form of 3 Service Models, 4 Deployment Models.

Deployment Models:


Service Models:

Once the user figures out the cloud deployment model, the next step is to decide the service model. There are 3 Service Models

Due to the increase of demand in adapting and utilization of cloud Services, vendors came up with new models like



Popular Players:

The Demand is constantly increasing and Vendors are trying to provide as many flexible service models as they can provide. More advanced implementations like AI Implementations, IoT deployment, Blockchain Technologies can also utilize the cloud services and computation power.

To Secure this environment, organizations have developed advanced architecture models like ZTA and SASE, which I have covered in previous articles.
