INTRODUCTION TO CLOUD COMPUTING

Session 1

History of cloud computing

• Need for Utility : (Electricity, Telecom) : Delivering computer resources over global network

1969 (ARPNET)

1970(mainframes)

1980(PC adoption)

1990-till date (internet economy)

1999 (salesforce.com)

2002(Amazon Web Services)

2004(Private Cloud)

2009(web 2.0)

Mainframe

Full virtualization

Paravirtualization

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

• 5 characteristics• On demand self Service, Broad Network Access, Resource pooling, Rapid Elasticity and Measured services

• 3 Service Models•SaaS, PaaS, IaaS

•4 Deployment model•Private Cloud, Public Cloud, Community cloud, And Hybrid Cloud

How Cloud Computing works 1/2

• Using resource pools to share common resources

• Server Virtualization

• Network Virtualization

• Storage Virtualization

• Virtualization to cloud : IT –as-a-Service

• Data Centre transformation to shared Infrastructure

How Cloud Computing works 2/2

IT Service Management

Software as a Service

Platform as a service

Infrastructure as a service

Virtual Infrastructure Architecture

Virtual Infrastructure Management

System StorageBackup

and Recovery

Networks SecurityTraditional Roles still essential

New role emerging•Cloud Architect•Cloud Admin•Cloud Capacity Planner•IT automation engineer

New focus Area : Cloud services and operations management

Business and Financial management

Application for Business

• Application testing and staging

• Temporary processing and storage needs

• Data archiving

• Virtual Desktop Infrastructure (VDI)

• Supplier management

• Back-office optimization

• Sales force management

• Project management and collaboration

Infrastructure Cloud Services Provider

• AWS

• Microsoft Azure

• Google App engine

• Rackspace Cloud

Cloud Computing Architecture 1/4

Cloud Computing Terminologies

• Communication-as-a-Service (CaaS)

• Infrastructure-as-a-Service (IaaS)

• Monitoring-as-a-Service (MaaS)

• Software-as-a-Service (SaaS)

• Platform-as-a-Service (PaaS)

Advantage

• Access

• Scalable

• Cross Platform

• No upfront cost

• Data Security

• Integration

Disadvantage

• Security

• Response Time

CLOUD NETWORK AND PRIVATE CLOUD

Session 3

AMAZON WEB SERVICES CLOUDSession 4

Amazon Web Services (AWS) -robust, scalable and affordable

infrastructure for cloud computing.

This session is about:

5 Benefits of Using Amazon Web Services

1. Pay-per use model

You are only charged for disk space, CPU time and bandwidth that you use.

2. Instant scalability

Your Service automatically scales on AWS stack.

3. Reliable/Redundant/Secure

Infrequent outages (so far).Data is redundant in the cloud.

All services have built-in security.

* Soon will add Comprehensive to the list.

4. Most services accessed via simple REST/SOAP API

Libraries are available in all major languages.Minimal learning curve.

5. Amazon - Experience & Commitment

Amazon has been doing this for ~15 years. Company-wide commitment to AWS.

Amazon Web Services Stack

Simple DatabaseService (SimpleDB)

Elastic Cloud Service (EC2)

Simple StorageService (S3)

Simple QueueService (SQS)

Elastic Compute Cloud (EC2)

On-demand grid

EC2 in a Nutshell

QuickTime™ and a decompressor

are needed to see this picture.

MachineImage

(OS + Apps)

Usage:

• Create Machine Image• Deploy the image to S3• Start 1 or more instances• Use it as regular machine(s)

Main Options:

• Dynamic/Static IPS• Choose cores• Choose locations• Persistence via EBS

Sample EC2 Use Cases

Batch Processing

All instances are configured with the same code. Each instance operates on a subset of data. Partitions are specified in configuration file.

Web Service

All instances are configured with the same code. One or more instances are configured as load balancers

(HAProxy for example). DNS Server distributes requests between load balancers.

EC2 vs. Web Hosting Company

Instantly add new instances

Full-control over the machines and choice of the environment

Likely cheaper (but depends on your exact situation)

Need to put the images together and manage instances

No dedicated technical support

(but there is premium support and RightScale solutions)

Simple Storage Service (S3)

Large media and everything else storage.

S3 in a Nutshell

Client

Put/Get objects into bucketsbased on unique keys.

Main Features:

• Public/Private access.• Support for large objects.

Amazon S3

Bucket 1 Bucket N…

Put object Get object

Sample S3 Use Cases

Image/Video storage

Put your media once on S3 and then serve it up

Reads are 10 times cheaper than writes!

Serialize your Java Objects

Define unique key based on the object attributes

Write out binary serialized version to a stream

Write bytes to S3

Read them back when needed

Simple Database Service (SimpleDB)

Basic database and indexing service

Simple DB in a Nutshell

Client

Create flat database with auto-indexed tables.

Main Features:

• Each attribute is indexed.• Record structure is flexible.• Basic operators in queries• Supports sorting.

Simple DB Domain

Record 1

Put record

Get recordQuery records

Key1 Attributes: A1,A2…

Record N

Key2 Attributes: A1,A2…

Sample SimpleDB Use Cases

Index Media files stored on S3

Use the same key as on S3

Write the record with each metadata element as attribute

Store flat objects

Use SimpleDB as a storage for non-nested data

Simple Queue Service (SQS)

Infinite Asynchronous Queue

SQS in a Nutshell

Writer

Create an infinite asynchronous queue.

Main Features:

• Multiple queues• Upto 4K messages• Message Locking

SQS Queue

Message 1

SendMessage

ReceiveMessage

Message N

Reader

Sample SQS Use Cases

Twitter Friend Update

For each update generate a task to update friends

Process updates in order

Publish/Subscribe

Post messages to the queue to inform multiple subscribers

Process Pipeline

Use different queues to put, for example, and order through a pipeline.
