Services Provided By AWS

What is Infrastructure as a Service (IAAS)?

~ IAAS is a service which provides Infrastructure to build any website or application to run smoothly without any physical servers in on-premises.

~ As an end user you don't need to manage the servers or computer physically, it is managed by AWS on behalf of you.

~ Example: You want a supercomputer for your final year project, but you are in college hostel, and you don't have space to keep this supercomputer and maintain all the time. Hence you have created an AWS account and spined up a supercomputer using AWS EC2 Service, and you are done. Whenever you need to access the supercomputer, you can start and use it and shutdown it and physically it is not present with you but within AWS data center. Hence you goal of developing final project is done without you managing any of the infrastructure components.

What is Platform as a Service (PAAS)?

~ PAAS is a service which provides Platform to run the code/application.

~ As an end user you don't need to manage installation of software's and updates and tools to run your applications or project, it is managed by AWS on behalf you.

~ Example: You can host your website (simple html/css) code in AWS PAAS service and go for a round trip around the world and comeback and see your website will be still running, running and running. Also assume somehow your website went viral and lots of user started to use it, from 100 users to 100,000 users a day started to view your website. Behind the scenes all the load balancing, auto-scaling adjustments based on the traffic everything is done by AWS on behalf of you. Cool isn't?

What is Software as a Service (SAAS)?

~ SAAS is a service which gives you a software directly to consume and just use it directly.

~ You don't need to be technical person to avail this service, just if you know how to use and you have use case. Just you can plug and use it, simple as that.

~ Example: You have seen many video platforms, there you are just uploading videos or viewing videos without worrying about how that application runs and who manages their server right? Also, you have drop box or one drive or google drive to upload your files and pictures without worrying about how this application maintained or managed right? Just you are consuming on the fly without worrying about anything technically. Am I right, again? If you agree these points, then that is best example for SAAS I can say.

BIG DATA ANALYTICS

BIG DATA ANALYTICS Have you ever hit upon how Amazon and Flip kart could possible verdict what we want; how the Google auto completes our search; how the YouTube looks into videos we want to watch? When we open YouTube, we will be at sixes and sevens, when we find ads related to what we have searched earlier in the past days. This is where we find ourselves in the era of big data analytics. More than 3 trillion bytes of information are being generated everyday through our smart phones, tablets, GPS devices, etc. Have we thought about what can be done with all these information? This is where the data analytics comes into play. Big data analytics is just the study of future build up to store data in order to extract the behaviour patterns. The entire social networking website gathers our data which are related to our interest which is usually done by using our past search or any other social information. Data analytics will lead to a walkover in near future.

Amazon Elastic Compute Cloud (Amazon EC2)

Amazon Elastic Compute Cloud (Amazon EC2) What is AWS EC2 ? Amazon Elastic Compute Cloud, EC2 is a web service from Amazon that provides resizable compute services in the cloud. What do you mean by resizable in AWS EC2 ? You can quickly scale up or scale down the number of server instance you are using based upon on your traffic. What is called as Instance? An instance is a virtual server for running applications on Amazon’s EC2. Simply Virtual Machine is called as Instance(i.e)it holds the HDD, OS, RAM, Network Connection Whatever things that are need to run a system. Note : Everything is Virtual You can’t able to see the HDD, RAM , or CPU. Only thing is you can able to configure it based on your need. So here is the Definition…. Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. Why Amazon EC2 ? Pay-as-you

CLOUD COMPUTING SERVICES

Services provided by Cloud Computing 1. Software as a service : It is process by which the software will be provided by the cloud server's. Instead of using the software in our local machine we can directly use the cloud services directly to get our work done. Example : Google Slides, Google Docs, Google Sheets, Zoho Writer,....etc. 2. Platform as a service : It is process by which you can directly use platform like windows , linux , Mac, ....Which ever you need to done your work. Example : There are certain software which might be run only certain platform. Assume I have windows operating system but i am doing research in BIG DATA. There Linux Operation system might be handy for my research work. Where it is hard for me to put Operating System again and again to my local machine and taking backup data. So Cloud Computing Services Makes our work easier whatever platform we need it will provide us without any loss in data or hard backup pro
