What is Cloud Computing?
In simple words,
Cloud computing is a computer resource such as hardware and software services provided through the network. Python and Java are the best languages to use for cloud computing.
Most of the current cloud is actually a very large data centre, where thousands of servers are arranged, spending millions of dollars to keep them cool.
But with thousands of these servers, many complex problems of clients are solved very easily.
Types of Cloud Computing
There are three main types of cloud computing services.
Software-as-a-Service is a model for software distribution and the customers access the software over the internet via a standard web browser. A simple example of SaaS is Gmail and some well-known examples of SaaS are – Netflix, Google Apps and Cisco WebEx etc.
Infrastructure-as-a-Service is the primary layer in the cloud computing model. It is a public cloud environment. It is a service model that delivers computer infrastructure based on an outsource. Famous examples of IaaS are – Microsoft Azure, Amazon Web Services (AWS) etc.
Platform-as-a-Service is a computing platform including operating system, programming language execution environment, web server, database etc. Some examples of PaaS are – Windows Azure, Heroku, and Apache Stratos etc.
Cloud Deployment Model
Three main cloud deployment models are there-
Systems and services are easily accessible to the public in the public cloud. Some examples of public cloud are – Amazon, IBM, Microsoft, Google, etc.
Public cloud has a low cost than the private or hybrid cloud. It provides a large number of resources to the customer, so it is reliable.
Public cloud is easily combined with the private cloud because it has flexibility. It is accessible through the internet.
But as the resources are shared publicly, so it doesn’t give you high-level security.
A private cloud gives you the ability to access the system and services within the organization. Third-party will also be able to manage it internally. It gives you high security.
It’s challenging to propagate private clouds globally, and also it is very costly.
Hybrid cloud is the combination of public cloud and private cloud. It has both of the features of public and private cloud. It gives you security, and it is cost-effective.
As the hybrid cloud is the combination of public and private clouds, its networking becomes complex.
How Does Cloud Computing Work?
Cloud computing is a method where software, resources and information are shared with the help of network. Physical servers which are maintained and controlled by the providers of cloud computing, store the information. With the help of an internet connection, users can access the stored information.
The presence of these three main components is required for the proper working of cloud computing which are mentioned below. Cloud computing architecture is formed with these three components.
Front-end refers to the side which the computer user or client sees. Front-end includes the client’s or user’s computer or mobile device and the application required to access the cloud computing system. A web browser is the most required application, but other systems may require any other special applications.
This is the computer infrastructure used by service providers. It includes various servers, computers, operating systems, virtual machines and data storage facilities which are combined and form the cloud technology. Backend is also known as Backend-as-a-Service (BaaS). Monitoring the traffic and client demands and run everything efficiently are done by the central server.
This is the most valuable component because nothing can be done without networking. It allows the connection between front-end and backend via the internet.
Why You Use Cloud Computing?
Surely a question arises in your mind that why will you use cloud computing?
I’ll answer you.
Cloud computing is cost effective.
You don’t have to make huge investment to access the cloud. It is a constantly improving process. It improves its feature every day to be faster. Cloud computing gives you the feature of backup and recovery. If any disaster may happen you will be able to recover the data saved in cloud storage.
Cloud computing gives you security. The data saved in cloud storage is not stolen or publish but one drawback is that it can be viewed. As cloud computing has so many excellent features you can easily use clouds.
Some benefits of cloud computing
Cloud computing gives flexible approach users or consumers.
Cloud computing is cost-effective because it doesn’t need any huge investment.
Cloud has a feature called scalability. The number of users can be increased or decreased as much as required with the change of time.
Cloud computing is a constantly improving process. It is a very faster and less complex process.
Cloud applications are easily accessible and it gives you the security to access the cloud applications from anywhere or from any other device.
Patching, upgrading and testing none of these are required for cloud applications because all of these are handled on the cloud.
Some disadvantages of cloud computing are
- As cloud computing is an internet based service so services outrage may be occur for any reason.
- Sometimes unfortunately cloud provides less security and privacy.
- As cloud is an online process it suffers from online server attacks.
- Vendor lock-in is another disadvantage of cloud computing.
Cloud computing is accepted globally. The great features of cloud computing makes it very popular all over the World and the use of this technology increasing rapidly.
In UK, cloud based service companies has grown rapidly from 48% in 2010 to 88% in 2017 and most of the users expect to increase their adoption of cloud services.
If you are new to cloud and trying to migrate all your data to it, make sure to have it done
under the guidance of expert professionals. Go for a ITAD services company like
Dataknox. This will not only help you in cloud migration but also take care of your old data
centers, hardware and network etc.
So, it is expected that cloud computing will widely expand in India very quickly.
