Cloud Computing

Module Introduction

Welcome to the module on ‘Introduction to Cloud Computing and AWS Setup’.

In this video, you will get a brief glance at the topics to be covered in this module.

Traditional Data Centres

A data centre is a dedicated space within a building, in which all the computer systems and other components related to storage or network are kept.

The following are the two ways of deploying a traditional data center:

On-premise Systems-the data centres are hosted and maintained within the organisation.
Colocation- The data centre used by an organisation is hosted by a third-party firm. the organisation provides the required computer servers, storage and networking, whereas the third-party firm provides the power , cooling and physical security. this is similar to the relationship between the property manager and the customer who user a rental space to facilitate equipment.

Benefits of Colocation Data Centre

Risk Management: In colocation data centres the network traffic is not affected in case of power failure. it ensures that there is continuity in case of a major disaster.
Security: Latest security technology is provided to the data centres that prevent unauthorised access.
Cost: It results in costs savings like reduction in capital expenditures related to the power source, backup generators etc.
Bandwidth: Colocation provides the amount of bandwidth required by an organisation to function properly.
Scalability: Enterprises can expand according to their needs through colocation.
In this module
The first session of this module is Cloud Computing. This session highlights the basic concepts of Cloud computing. You will learn about the benefits of using cloud over traditional systems. This session will also explain the various types of cloud deployment models and cloud service models. The objective of this module is to give you an overview of how cloud-based applications work and what services are provided by the prevalent cloud providers.
The second session is AWS-EMR Instance Setup. The session provides the instructions to set up your EMR machine i.e. your Big Data Lab for the future modules. The objective of this session is to help you set up an environment where you can practice the tools taught in this program. Please follow the steps carefully.
The third session is an introductory session on Virtual Machines. This module will provide you with a very basic overview of the mechanism of virtual machines

Guidelines for in-segment & graded questions

There will be a separate session for Graded Questions. The other sessions will contain questions that will not be graded. The graded questions in this module will each have 10 marks for a correct response and 0 for an incorrect response. Each graded question will have only one attempt while the non-graded question may have one or two attempts depending upon the question type and the number of options.
