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.

On-Demand Self-Service

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)

Private Cloud

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
