Transcript of CIS Module 1_ Journey to the Cloud
MODULE – 1
JOURNEY TO THE CLOUD
Module 1: Journey to the Cloud
Upon completion of this module, you should be able to:• List the Business drivers for Cloud computing• Define Cloud computing• Build Cloud infrastructure• Discuss the steps involved in transitioning from CDC to Cloud
Journey to the Cloud 2
Why Cloud Computing?
Journey to the Cloud 3
Aging data centers
Globalization
Application explosion
Storage growth
Cost of ownership
Acquisitions
IT Challenges
“70% of the budget to keep IT running, 30% available to create new value”
“…that needs to be inverted”
“Weeks of planning, justification, and deployment and then we’re stuck with it for 5 years – even if our needs change in a month…”
“…or we could just buy it as a service – right now”
“Most of our legacy applications are stable and predictable”
“…we need to incrementally improve efficiency without disruption”
“but, new, more dynamic and fluid approaches to IT must also be leveraged for new applications and changing legacy applications”
“…new, revolutionary IT model is required”
Emergence of New IT Model – Cloud Computing
A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., servers, storage, networks, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. – NIST
Cloud Computing
• Essential Cloud Characteristics On-demand self-service Broad network access Resource pooling Rapid elasticity Measured service
Journey to the Cloud 4
“Computing may someday beorganized as a public utility, just as the electricity is organized as a public utility”
– John McCarthy, speech at MIT in 1961
Building Cloud Infrastructure
• Building Cloud infrastructure is a journey in phased approach: Understand your existing infrastructure Virtualize your infrastructure
Virtualization enables resource pooling and rapid elasticity
Deploy service management tools to deliver Cloud service Automate service provisioning to
enable on-demand self-service of computing resources over the network
Facilitate measured services
Journey to the Cloud
Infrastructure should meet essential Cloud characteristics
Cloud Infrastructure Management and Service Creation Tools
Virtual Infrastructure
Physical Infrastructure
Applications and Platform Software

Understand Existing Infrastructure – Classic Data Center
• Classic Data Center (CDC) is a facility that provides IT resources to process data• The core elements of a classic data center
are: Compute Storage Network Application Database Management System (DBMS)

Virtualize the Infrastructure
• Virtualization is a technique of abstracting physical resources and making them appear as logical resources• Virtualization may be implemented at compute, storage,
network, and/or application layers Refers to as a Virtualized Data Center (VDC)
• Virtualization Benefits: Optimizes utilization of IT infrastructure Reduces cost and management complexity Reduces deployment time Increases flexibility
Journey to the Cloud 7
Deploy Service Management Tools
• Service Management tools help to create and deliver Cloud services• Automates and Optimizes:
Service request processes Provision and delivery of services
• Enables Metering of resource usage• Manages of physical and virtual resources
