What is a Cloud?


This diagram is produced from a description by NIST or what cloud computing is. And what I'm going to do is to describe all the various parts of it and give you some examples. So first of all, the cloud is out there. Anybody can use it from anywhere. So availability is good and accessibility is good. It really becomes a ubiquitous computing environment. It's convenient, 24/7 you don't have to turn it off, turn it back on, whatever, it's always running for you. And because of all of the input from all the industries into Cloud Computing, it's becoming very convenient to use.

Big Data Revolution and Clouds ?

Image
So Big Data, where will it take us? Well, it's another revolution, it's built on clouds. The data collection's too large to transmit economic clear of the Internet. You're talking about petabytes of collections. The computation is data intensive, lots of disks, networks, and CPUs. The overhead of maintaining cyber infrastructure for that is very expensive, but why not share it amongst the community? So for example, Google Maps is a huge infrastructure investment, but it allows all sorts of businesses. You're going to see smart cities building on some of those infrastructures, on some of the data collected for smart cities. Users buy Big Data services from Clouds and they share the overhead. So they're sharing out the cost of putting all that Big Data together. The essential part to all of this is here. This Big data is going to be easy to use. It's going to be easy to write programs for. It's going to provide you fast turn around, so you know

Course Description

Course Description Welcome to the Cloud Computing Applications course, the first part of a two-course series designed to give you a comprehensive view on the world of Cloud Computing and Big Data! In this first course we cover a multitude of technologies that comprise the modern concept of cloud computing. Cloud computing is an information technology revolution that has just started to impact many enterprise computing systems in major ways, and it will change the face of computing in the years to come. Course Goals and Objectives Upon successful completion of this course, you will be able to: Understand what cloud computing is and why it is important Get a picture of the economics of cloud computing Learn about Big Data (much more about big data in the second part of this course) Learn about many fundamental technologies that enable cloud computing, such as software defined architectures, virtualization and containers Learn about many “glue” technologies that e
