Benefits of Enterprise Grid Computing

IT represents good

value for moneyIT becomes a

business enabler

disparate IT Infra

to manage

Low business

satisfaction for

price/performance

High administration

costs

Long provisioning time

for new projects,

products or services

Every project has to

purchase new hardware

under utilization of

Infrastructure resources

GOAL

Enterprise Grid Computing: Solving critical IT challenges

Significant cost saving

In IT infrastructure

Differentiate from competitors

by being able to introduce

products & services quicker

Improve speed

of delivery

Improve resiliency

& utilization

IT is flexible and responsive

to business change

GOAL GOAL

HA can only be afforded

by mission-critical

applications

Service Level ManagementAlign IT and business customers on service levels

• Define & Model

– Define services and systems

– Set service level goals

– Map business service to system resources

– Visualize in topology views

• Monitor

– Measure service performance against goals

– Availability, Performance and Usage

• Report

– Single view of status of each service

– Out-of-box and custom reports

Situational Analysis – When to deploy

What?

• Oracle VM and RAC / Application Server Grid

• Coherence & TimesTen

25

Oracle VM vs RAC – Dynamic Operations

Oracle VM RAC / Application Server Grid

Add/Remove CPU Add Server

Simple More Complex

Can scale to size of SMP Very high scalability

Cannot change from single

instance to RAC online

Add/Remove Memory Remove Server

Not all database memory

dynamic Simple

Need to wait for long running

processes to complete

Can easily move resources

between partitions Services

Allows fine grain allocation of

resources

26

Oracle VM vs RAC – Business Continuity

Oracle VM RAC / Application Server Grid

Supports existing failover models Active-Active model only

Active-Active More complex

Active-Passive Fastest failover times

Auto Restart capability Highest availability

Active-On demand Very high scalability

Slower failover, need to provision deployment decision

Lower cost

Can handle server failures only

Disaster Recovery Disaster Recovery

Support for active-on demand

model RAC plus dataguard / AS Guard

Supports existing models

Recommend architecture for

maximum availability

ability to simulate DR scenarios

can be used in physical or virtual

environment once certification is

completed

requires 3rd party replication

Pre-implementation Grid Discovery

Process

• Look for the following situations for potential Enterprise Grid exercise:• Needs budget exception to buy larger SMP box

• Recent outages of 24x7 mission critical applications

• Building a new data center or DR site

• Architecture review board developing 5-year plan

• Planning infrastructure upgrade

• Recent success with virtualization

• Already using grid techniques in other tiers

• Share Services Imperative

• Desire to commoditize hardware

• Legacy Modernization Project

• Performance, Scalability Issues with Legacy Infrastructure

30

Checklist for discovery process

• IT resources (servers & applications etc) and who owns them• The average CPU utilization across all servers in your data center environment• The level of standardization across technology stack (eg, servers, storage,

databases, software, OS, software infrastructure, middleware and infrastructure services)

• The definition of SLA and current service level and the intended service level by end users?

• The average time take to provision the requested infrastructure resources to support a project

• The current level of standardization of IT processes and Management tools in current data center environment

• The current level of automation in the IT infrastructure management• The distribution of IT operational cost

31

Service Level

Critical Applications

• Business Critical Txn Application(s)

• High User Vol, OLTP Rates, Reporting

• HA Infrastructure (Cluster)

• Active/Active

• Leverage on Application data grid

Shared Applications

• Important to Business

• Lower User Vols (sporadic), OLTP and

Reporting

• Multiple Applications on Shared GRID

• Active/Passive

• Leverage virtualization

Service Level 0 Service Level 1 Service Level 2 Service Level 3

Service Level Definition- Sample

50% More Efficient, 50% Better Quality of Data, 50% FasterAs is To be

Application data Grid (SL: 99)

• Data Acquisition Processing manual with

multiple failure points

• Data acquisition automated via Message

Based GRID into a single ODSApplication Server Grid (SL: 99.9)• Transform Processing serialized across

flat files

• Rules processing GRID acts on ODS,

creates materialized views

Data Grid (Five 9’s)• ODS in many instances, not virtualized,

high TCO and low accuracy

• Highly available RAC enabled ODS with

10g BI features, optimized use of hardware

Storage Grid (Five 9’s)• Access method not global, many

technologies, not agile• Data Integration and Portal Access

Hardware and OS Interoperability

• Design goal: Similar experience across platforms

• Single code base

• Not advisable – standardization of platform will results

in TCO reduction, higher performance, and more

effective resource utilization
