An Introduction to AWS - EC2 (Elastic Compute Cloud)

Most recent two decades IT is following conventional methodologies for dealing with its framework since the beginning of Cloud administrations, for example, Amazon Web Services, Google Cloud Platform, IBM Cloud and a lot all the more giving on the web foundation administrations. Associations have acknowledged an adjustment in their working model, if an association searches for an extension to expand its registering power, they just get it online by starting a virtual machine on the cloud. Virtual machines can be immediately propelled and shutdown through programming interfaces, offering adaptability to the client rather than customary methodologies. There were times when one was restricted by the boundaries of a machine e.g.; a data scientist has a large scale of data and would like to perform some analysis, however, encounters an error as below while uploading this data. > data <- read.csv (file='no\_of\_bug.csv') Error: cannot allocate vector of size 500.0 Mb The error is the result of the unavailability of the RAM since the operating system does not have enough RAM available as there are many solutions available of such problems following the traditional approach one should upgrade the RAM of the machine with the restriction to the RAM up-gradation limit to the machine's compatibility. However, there is another way by introducing the concept of virtualization in the could with more RAM and CPU. This paper explores the concept of Virtual machines on AWS EC2 as they are called instances with many advantages few of them includes being highly scalable (one can choose instances with more CPU and RAM etc.) most reliable and scalable easy to use for users as pay for what being used also allows a selection of different platform (OS) as an outcome of this paper will create an understating of the working fundamental of AWS EC2.
