Enterprise Overview Business View Computing Technology View 3
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 $$ Cash Flow $$ Operating Activities Investing Activities Financing Activities 4
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) 5
Computing Technology Overview Personal Computing Distributed, Grid, and Edge Computing Cloud Computing Enterprise Computing 6
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. 7
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. 8
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. 9
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. 10
Enterprise Computing Technology Decisions Disruptive Technology and Competitive Advantage Cost of Information Technology Service Levels Infrastructure Matters 11
Enterprise Computing Technology Decisions 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. 14
