Cloud Computing

Cloud Computing is a general term used to describe anew class of network based computing that takes place overthe Internet,

Cloud computing is an umbrella term used to refer toInternet based development and services

A number of characteristics dene cloud data, applicationsservices and infrastructure: Remotely hosted: Services or data are hosted on remote

infrastructure. Ubiquitous: Services or data are available from

anywhere. Commodifed: he result is a utility computing model

similar to traditional that of traditional utilities, like gas

and electricity ! you pay for what you would want"

OpenStack Cloud

OpenStackis a community of open sourcedevelopers, participating organiations andusers who are building and running theopen

source cloud operating system.OpenStackis an Infrastructure as a service which is

known as a Cloud Operating System, that takesresources such as compute, storage, network,virtualization technologies and controls those resourcesat a data center level

OpenStacks basic requirement: Cloud mustbe simple to implement and massively scalable

;irtual 6achine: A software package, sometimes using hardwareacceleration, that allows an isolated guest operating system to run within ahost operating system.

Stateless: 2nce shut down, all -? states disappear.

-ypervisor: A software platform that is responsible for creating, running,and destroying multiple virtual machines.

2penStack is hypervisor agnostic.

Key Management

efore you instanciate a ;6, you need to create atleast one key pair. his key pair will be inBectedinto the ;6, allowing you to SS- into the ;6

Fix the permissions on the generated private key$ chmod 0600 userkey.pem

he ssh private key that was generated earlier can now beused to log into the ;6

ssh !i userkey.pem rootD
