Enterprise Business View

• Make decisions to increase sales, revenue, and favorable cash flow

• Enable clients to conduct business with ease and speed

• Manage expense while mitigating risk to business operations

• Provide reliable services necessary to complete daily business transactions

• Provide employee's with the means to maximize productivity

• Relentless focus on improving value and competitive advantage

Enterprise Computing Technology View

It is all about the data and associated services

• Daily business transactions involve computing infrastructure

Read & update data

Service Level Agreement (SLA)

Information Technology Facilities and Cost

• Development of new computing services

Increase sales, reduce costs, or gain competitive advantage

• Data backup and recovery (a legal fiduciary duty for publicly held enterprises)

• Distributed, Grid, and Edge Computing

Personal Computing

Personal computing workstations enabled knowledge workers to have

relatively “cheap” access to computing resources.

Some speculated in mid 1990 that these “cheap” computing resources

would completely displace the larger “more expense” centralized computing

resources. The result was a false and self servicing prophetic phrase, “the

mainframe is dead”.

In recent years, PC has become more and more difficult to pin down. PC

can be any personal device with a microprocessor.

The increased speed of the internet accompanied by the advancements and

miniaturization of computing electronics has enabled smart phones and the

rapidly increasing number of devices categorized as the “Internet of Things”.

Distributed, Grid, and Edge Computing

The technology introduced by personal computers lead

to innovative business enabling computing paradigms

Distributed Computing Networked computers communicate and coordinate their

actions by passing messages. The components interact with

each other in order to achieve a common goal.

Grid Computing A form of distributed computing whereby a "super virtual

computer" is composed of many networked loosely coupled

computers acting together to perform large tasks.

Edge Computing A new frontier of computing applications, data, and services

away from centralized nodes to the logical extremes of a

network. It enables analytics and knowledge generation to

occur at the source of the data, aka the Grid Edge.

Cloud Computing

Cloud computing is the result of the evolution and adoption of existing technologies and paradigms.

The goal of cloud computing is to allow users to take benefit from all of these technologies, without the

need for deep knowledge about or expertise with each one of them.

The cloud aims to cut costs, and helps the users focus on their core business instead of being impeded

by IT obstacles.

According to the official National Institute of Standards and Technology's (NIST) definition, "cloud

computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool

of configurable computing resources (e.g., networks, servers, storage, applications and services) that

can be rapidly provisioned and released with minimal management effort or service provider

interaction.“

During the past decade, many used Cloud computing terminology to promote their off premise data

storage and services which spawned new business opportunities. This is attractive to businesses as an

opportunity to reduce the cost of in-house Information Technology hardware, software, and facilities.

Enterprise Computing

Enterprise computing is a buzzword that refers to business-oriented

information technology that is critical to a company's operations.

Enterprise computing may include all the previously discussed computing

paradigms in addition to the most trusted and proven industrial strength

computing platform that managed business critical data for over 50 years.

z Systems are latest generation of IBM “mainframes” that were originally built

from the ground up to maximize data I/O throughput with additional design

characteristics required by large enterprises where failure to meet SLA is

both costly and potentially catastrophic.

Decades of business critical applications were developed and were

continually improved on the generations of IBM “mainframes” where one of

the original design characteristics included upward compatibility.

Disruptive Technology and Competitive Advantage

12


Cost of Information Technology

“Cheap” and “Value” are very different

Common budget practice includes a percentage of the overall enterprise

revenue being allocated to Information Technology. The job of the CIO is

to maintain and advance the enterprise Information Technology within

that revenue percentage.

IT decisions require significant study and skill due to rapidly expanding

computing technology has made IT decisions.

Cost of power has become a significant data center expense.

13


Service Levels

• The following can be very costly and potentially catastrophic:

Unscheduled computer system outage

Compromised client data

Unacceptable transaction response times

Lack of data integrity or loss of data

Inability to upgrade software and hardware

Inability to quickly implement new technology

• Information Technology decisions must mitigate the above risks.

How much risk to accept in a decision is a matter of the potential

cost associated with each risk.

Many have learned the cost details of these risks the hard way.

Infrastructure Matters

Data Centers with 30,000 – 60,000 – 180,000 Servers

Lots of expensive power Lots of physical servers Lots of cables

How about a single computer system with the following attributes:

• Can host 5 unique operating systems simultaneously, including Linux

• Can run many thousands of the these operating systems concurrently

• Network delay between the operating systems is near zero

• Unparalleled business data throughput capability

• Known for high speed, scalability, and security

• Has unparalleled high availability technology

This single computer system :

• Enables server consolidation significantly reducing costs

• Can have access to all critical data eliminating costly ETL

• Design characteristics that serve the most strict SLA

• Enables SOE, SOR, and SOI capabilities

Summary

• Think Big, Think Enterprise Computing

• Think Organization - People, Processes, and Services

• Cheap is Easy to Measure with potential of being very Expensive in the long run

• Value requires Insight to Measure with potential to be significantly Less Expensive while

enabling high availability, scalability, competitive advantage, unparalleled data security and

privacy for the businesses most critical data.

• Successful professionals know the Value of Quality and recognize Enterprise Computing

Economies of Scale when making Information Technology decisions
