They say “Change is the essence of life.” Everything has changed ever since the beginning of time. From the days in which man started communicating by means of inscriptions on stone walls to actually posting something in his/ her Facebook wall and from the time when he first started recording his/ her information in olden palm scriptures to storing them now in the cloud. Well, most of us have only come across this fancy tech word called ‘cloud storage’, but the actual functionality of it is beyond what our academic curriculum can provide us. To be simply said, if you own a Gmail account and are aware of the features of apps like the Google Drive and Google Photos offer, you are already a user of the cloud technology.
Cloud is simply an analogy for the internet. It is a vast network of connected servers which enables you to store information and data of all kinds without using the internal memory of your device. This involves a user to access, process and work on his/ her data over the internet or a particular which is connected with a number of other systems as well. Cloud computing is just another form of storage which is quite far away, whereas the data we store in our hard drive or any flash memory might be at our reach.
The history of Cloud’s existence:
Speaking of which, the main idea and concept of a typical cloud technology was conceived long back during the 1950’s when a single computer was the size of a room because of which the company could not offer each of its user a personal computer. They came up with the idea of ‘time sharing’ which is the basic building block of cloud computing. Later in 1969, was when the World Wide Web started to take over, the basic motive behind the invention of the World Wide Web aka the Internet was information sharing and the ability to access data from anywhere and anytime. In 1999, Salesforce became the first company to base their business on cloud computing. But it is only after the Amazon started their prestigious Amazon Web Services, many other sites started collaborating with the Amazon Web Services to deliver fully fledged cloud services.
Types of cloud computing:
Based on the services provided by this emerging technology, IT professionals have grouped cloud computing into three separate categories. They are:
- Infrastructure as a Service (IaaS)
This is where you buy the required amount of storage space on the internet which is simply a replacement of your hand core storage devices. This is also termed utility computing since you can pay a monthly subscription to use a particular service offered by it.
- Software as a Service (SaaS)
This is more or less like lending the application which is developed and is run on someone else’s system. Web based mail service providers and Google documents are considered the best examples of this kind of services.
- Platform as a Service (PaaS)
This is where you are the developer of a particular kind of service which you would want to host on someone else’s systems software by which he/ she can utilise your service’s full potential.
The pros and cons:
Just like two sides of a coin, cloud computing has its share of boon and bane in terms of quality, safety and other parameters. Let us have a look into what cloud services have to offer.
Cloud computing technology cuts down the investment costs on computer systems and softwares by introducing the concept of utility computing, in which one can buy only those services as per their requirements and then either add up to it when expanding your business or cut it down when scaling down your business. It gets you rid of all the old model heavy hard ware storage devices adding up to the efficiency of the business by enabling a huge range of services over a vast network of connected devices.
Despite the numerous advantages that the cloud technology offers, there are few issues which have to be dealt with concern as well. The main issue with cloud services is that it requires uninterrupted supply of broadband or internet service which is the only way to access our data which is stored in the cloud. This might not really be a huge issue in a country like the United States, but in other developing countries where this is not possible is hugely hit by opting for the cloud services. The security is however another alarming issue to be looked into. Nothing in the cloud can be considered safe as that which is stored in our very own hard drive of our very own personal computer.
Cloud like any other technology though makes life better and easier has its own risks which one have to handle with care. But the best one could do is hop along and keep updating oneself with the changes and trends hoping for the best.
