Journey to the Cloud

Why Cloud Computing?

“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

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

Essential Cloud Characteristics

1. On-demand self-service

2. Broad network access

3. Resource pooling

4. Rapid elasticity

5. Measured service

Building Cloud Infrastructure

Infrastructure should meet essential Cloud characteristics

• 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.

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

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
