Cloud! that not Rain - Nerd Platoon Cloud! that not Rain - Nerd Platoon

The word “Cloud” has been around for some time and is now cropping up even more. It’s very unlikely that you may not have heard about Cloud Computing. But when you hear it first time what questions should have come to your mind?

What is cloud computing?

In simple words, Cloud Computing is nothing but a process of accessing the different types of resources over the Internet. Those resources could be hardware, operating system, network, database, software, documents, intelligence, etc.

Is there any simple example?

When you have to crawl thousands of websites you need a huge layer of processors but if you set up that environment on-premises you never know whether the setup is well enough to meet your requirements. Later you may need to upgrade it. But once you complete crawling, you might not need so much of resources. And that leads to a huge waste of money. Now when it comes to cloud computing, you will be renting the resource, and once you are done with your requirement you can release or resize it anytime. And the best thing about cloud computing is that it will cost you in seconds.

Why Cloud Symbol, Does it lost with the rain?

The word ‘cloud’ in cloud computing originated from the internet symbol which  is actually represented by a cloud used in network diagrams. Not his understanding.

 

According to Wikipedia,  “The cloud symbol was used to represent networks of computing equipment in the original ARPANET by as early as 1977,[9] and the CSNET by 1981[10]—both predecessors to the Internet itself. The word cloud was used as a metaphor for the Internet and a standardized cloud-like shape was used to denote a network on telephony schematics. With this simplification, the implication is that the specifics of how the endpoints of a network are connected are not relevant to understanding the diagram.[11]”

What are the benefits of the Cloud?

Cost Effective – Reduces the resource expense Scalability –  Easy and Fast to resize resources Security – Features a robust architecture  Mobility – Can be managed from any part of the world with any internet device. Disaster Recovery – Just in time backup and distribution of resources prevent disaster. And many more..

What are the most common Cloud services? 

While we’ll go through the most common or well-known below, the so-called “aaS” (As a Service) propositions (Network aaS, Storage aaS, Monitoring aaS, Backup aaS, Container aaS, etc.) are growing at a rate of knots. Many of them fall under the three we’ve introduced you to here. They are the deployment models that, as with the types of Clouds, can adapt to users’ needs. The main difference lies in the extent of users and companies’ responsibility and control. Infrastructure as a Service (IaaS): this is RAM, CPU, storage and communications; it forms the technological foundation for the rest of the services. Platform as a Service (PaaS): the often-overlooked infrastructure that runs underneath the platform and adapts according to demand, enabling us to concentrate on the apps. Software developers often use it. Software as a Service (SaaS): self-contained, subscription-based services we can access without installing them locally. We can forget about the hardware, operating system, platform, etc. and focus solely on using the app. The provider carries out maintenance and updates. The image below shows the differences between the deployment models, with the services that each one affords:
