What is Amazon Web services?


Well, before we begin, let’s break the word and understand it’s individual meaning in layman language. Amazon + Web Service: Amazon is the world largest ONLINE RETAILER and a prominent cloud service provider. The other word i.e. “cloud service provider”. To understand the meaning of cloud service provider, let’s learn first about the cloud computing in simple words. Cloud is used as a metaphor for the “internet”. So, now we can say that it’s a type of internet based computing, where different services – including servers, storage and application are delivered to an organization’s computer and devices through the internet. We can also compare as, cloud is the mixture of air, vapor and liquid water just like cloud computing is a mixture of variety of facilities like servers, storage and application. And now comes the word Web Services, in layman terms, web services is a technology which enables the interaction between any two applications.

Let’s take an example in order to get a clear picture.

Consider a movie booking site. When user book for a movie and enter his/her detail, he/she has to make the payment and for that the site requires user to select the mode of payment. Let’s suppose he/she selects Credit card as the mode of payment, now user has to enter all credit card detail. Obviously these details cannot be authenticated by the movie booking site. It has to request to the concerned bank to authenticate the details provided by the user. That’s where WEB-SERVICES come into play. It makes the interaction between two applications possible and it accomplish serving data in the standard format such as XML or JSON. This will result the bank to response accordingly to the request made by the movie booking site (in this case).


So, till now we are almost done with the meaning of Amazon Web Service. Now let’s learn about its:
