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)

Computing Technology Overview
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”.

Computing Technology Overview
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.

Computing Technology Overview
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.

Computing Technology Overview
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
Enterprise Computing Technology Decisions
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
Enterprise Computing Technology Decisions
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
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
