Business Drivers
  • Cost Saving
  • To reduce up front investment in infrastructure
  • Elasticity
  • Need to quickly adjust to changes in
    infrastructure requirements
  • Reduce time to market

Defining Cloud
  • Wikipedia
  • Cloud computing is Internet-based computing,
    whereby shared resources, software and
    information are provided to computers and other
    devices on-demand, like a public utility.
  • Gartner
  • Style of computing in which scalable and elastic
    IT-enabled capabilities are delivered as a
    service to external customers using Internet
    technologies
  • Forrester
  • Standardized IT capability (services, software,
    or infrastructure) delivered via Internet
    technologies in a pay-per-use, self-service way.

13
NIST Definition
  • Cloud computing is a model for enabling
  • Ubiquitous,
  • Convenient,
  • On-demand network access
  • to a shared pool of configurable computing
    resources
  • Networks
  • Servers
  • Storage
  • that can be rapidly provisioned and released
    with minimal management effort or service
    provider interaction.

14
NIST Definition
Broad Network Access
Rapid Elasticity
Measured Service
On-Demand Self-Service
Resource Pooling
15
Ubiquitous Network Access
  • Ubiquitous network access means that the cloud
    providers capabilities are available over the
    network and can be accessed through standard
    mechanisms by both thick and thin clients.

16
Rapid Elasticity
17
Rapid Elasticity
  • Elasticity is defined as the ability to scale
    resources both up and down as needed. To the
    consumer, the cloud appears to be infinite, and
    the consumer can purchase as much or as little
    computing power as they need.

Public Cloud (Hostel)
Public Cloud
  • Available to everyone. Anyone can go and signup
    for the service.
  • Some public cloud concerns
  • Ownership
  • Control
  • Regulatory compliance
  • Data/Application security
  • Liability for SLA breaches

Internet
24
Private Cloud (Home in Gandhinagar)
  • Cloud infrastructure built in house
  • Retains control of resources
  • More security privacy
  • Can conform to regulatory requirement
  • Needs capital investment
  • Needs expertise to build and maintain

25
Hybrid Cloud(Home in ABad)
Public Cloud
Internet
  • Best of Both World
  • Workload is deployed mostly on private cloud
  • Resources can be used from public cloud when
    there is a surge in peak load (Cloud Burst)

IaaS
  • Core Computing Resources
  • Servers
  • Storage
  • Network
  • IaaS - Infrastructure as a Service
  • Infrastructure Management is abstracted from
    users
  • Elastic and On-Demand
  • Pay per use

28
IaaS- Use Cases
  • 20 servers daytime during peak load, but only
    need 2 during normal load
  • 100 servers for 48 hours to do some load testing
  • 10 TB of storage to backup my data
  • Infrastructure to implement my disaster recovery
    mechanism

29
Amazon a major cloud player
  • Over a period of time Amazon has built
  • A massively scalable distributed system
  • Scale capacity on demand
  • Reliable infrastructure
  • Amazon has made this infrastructure available to
    public
  • Known as AWS (Amazon Web Service)

New York Times
  • Used EC2 and S3 to convert 15 million scanned
    news articles to PDF (4TB data)
  • Took 100 Linux computers 24 hours (would have
    taken months on NYT computers

PaaS
  • Software
  • Application Servers
  • Messaging
  • Notification Services
  • PaaS - Platform as a Service
  • Platform for deployment and management of
    business applications
  • Management of infrastructure is abstracted
  • Load balancing, clustering, database management
    are also abstracted from users
  • Scales up or down automatically on demand

39
PaaS-Use Cases
  • Deploy web application on an infrastructure that
    can scale as demand grows
  • LAMP Stack
  • Ruby on Rails
  • Springs
  • Deploy Microsoft applications
  • No management overhead
  • Platform maintenance and operations
  • Database backup Disaster Recovery
  • Scalability Fault tolerance

SaaS Use Cases
  • Applications
  • HR
  • CRM
  • Financial,
  • Sales Automation ,
  • ERP etc
  • SaaS - Software as a Service
  • Application implementation, management
    configuration is abstracted
  • Disaster recovery, failover are taken care of
    behind the scene
  • Should provide integration capability to
    enterprise systems
  • Pay per users and functionalities availed or
    resources used like storage etc
