Introduction to Cloud

Introduction to Cloud
 Cloud computing is a type of Internet-based computing that provides shared
computer processing resources and data to computers and other devices on
demand
IaaS SaaSPaaS

What is OpenStack?

What is OpenStack?
 OpenStack is a set of software tools for building and managing cloud computing
platforms for public and private clouds.
 OpenStack is managed by the OpenStack Foundation, a non-profit that oversees
both development and community-building around the project.
 OpenStack is the future of cloud computing backed by some of the biggest
companies.

On-premises distribution
➢ In this model, a customer downloads and installs an OpenStack
distribution within their internal network

OpenStack-based Public Cloud
➢ A vendor provides a public cloud computing system based on the
OpenStack project

Hosted OpenStack Private Cloud
➢ A vendor hosts an OpenStack-based private cloud including the
underlying hardware and the OpenStack software

OpenStack-as-a-Service
➢ A vendor hosts OpenStack management software as a service and
customers use the software service

Appliance based OpenStack
➢ Nebula was a vendor that sold appliances that could be plugged into a
network which spawned an OpenStack deployment.

➢ Keystone is an OpenStack service that provides API client
authentication, service discovery and distributed multi-tenant
authorization by implementing OpenStack’s Identity API.

Glance
GLANCE
 The Glance project provides a service where users can upload and discover
data assets that are meant to be used with other services.
 This currently includes images and metadata definitions.
 Glance image services include discovering, registering and retrieving virtual
machine images.

Nova
NOVA
 Nova is an OpenStack project designed to provide power massively scalable,
on demand, self service access to compute resources.
 It is fault tolerant, recoverable and provides API-compatibility with systems like
Amazon EC2.
 It is built on a messaging architecture and all of its components can typically
be run on several servers.

Neutron
NEUTRON
 Neutron is a networking project focused on delivering Networking-as-a-
Service (NaaS) in virtual compute environments.
 Neutron has replaced the original networking application program interface
(API) called Quantum in OpenStack.
 Neutron is designed to address deficiencies in “baked-in” networking
technology found in cloud environments.

Swift
SWIFT
 Swift is a highly available, distributed and consistent object store.
 Organizations can use Swift to store lots of data efficiently, safely and cheaply.
 Swift powers storage clouds at Comcast, Time Warner, Globo and Wikipedia as
well as public clouds like Rackspace, NTT, OVH and IBM SoftLayer.

Cinder
CINDER
 Cinder is OpenStack’s Block Storage Service and provides persistent block
storage resources that OpenStack Compute instances can consume.
 This includes secondary attached storage similar to the Amazon Elastic Block
Storage (EBS) offering.
 In addition, you can write images to a Block Storage device to use as a
bootable persistent instance.

Horizon
 Horizon is the OpenStack’s Dashboard which provides a web based user
interface to OpenStack services including Nova, Swift, Keystone, etc.
 It allows users and administrators of the environment to interact with and
manage the various functional components without having to install any local
client tools other than a web browser.

Case Study

Case Study – Introduction
 Time Warner Cable is among the top three US cable
companies in the US, with annual revenues in the tens of
billions of dollars.
 It delivers digital cable, cable Internet, digital phone, home
security and cable advertising products and services.
 AVI Networks is their OpenStack provider.
 Their multi-location OpenStack private cloud caters to a large
group of application developers responsible for hundreds of
applications.

Case Study – Existing Challenges
Challenges with Existing Solutions
 Hardware ADCs are too inflexible
 Open-source solutions: Lacked advanced features and
high availability
 Virtual ADCs: Complex orchestration

Case Study – Problem Statement
Problem Statement
