Written for those starting a career in IT or whose career is well
advanced, this career guide shows how to blaze a path to success
through the jungle of modern IT. With a career spanning five
decades, the author shares lessons he learned the hard way so
readers do not have to learn them the hard way. By emphasizing the
importance of business processes and applications to IT, this book
explains how to understand the value and positioning of hardware
and software technology in order to make appropriate decisions. It
addresses the importance of IT architecture and the roles service
and systems management play. It also explains service level
agreements (SLAs) and provides sample SLAs. Readers learn how to
conduct IT assessments using SWOT (strengths, weaknesses,
opportunities, and threats) analysis. It also shows how to use
root-cause analysis (RCA) to detect the sources of failure and poor
performance. An overview of risk management and the steps involved
in developing a business continuity plan are also included. The
book looks at all facets of an IT professional's career. It
explains how to build an IT team and examines the roles and
responsibilities within the team. It shows how to provide
professional customer care to IT clients. Business executives
recognize the importance of IT, and this book shows technology
professionals how to thrive in the business world. It covers:
Making effective presentations Report and proposal writing
Negotiating and persuasion skills Running productive meetings Time
and stress management The book also discusses such important career
skills as listening, continual and incremental learning, and
communicating at all levels. From its templates and checklists to
its comprehensive and holistic view of a successful IT career, this
book is an indispensable guide for every professional working in IT
today and tomorrow.
This book on performance fundamentals covers UNIX, OpenVMS, Linux,
Windows, and MVS. Most of the theory and systems design principles
can be applied to other operating systems, as can some of the
benchmarks. The book equips professionals with the ability to
assess performance characteristics in unfamiliar environments. It
is suitable for practitioners, especially those whose
responsibilities include performance management, tuning, and
capacity planning. IT managers with a technical outlook also
benefit from the book as well as consultants and students in the
world of systems for the first time in a professional capacity.
This book starts with the basic premise that a service is comprised
of the 3Ps-products, processes, and people. Moreover, these
entities and their sub-entities interlink to support the services
that end users require to run and support a business. This widens
the scope of any availability design far beyond hardware and
software. It also increases the potential for service failure for
reasons beyond just hardware and software; the concept of logical
outages. High Availability IT Services details the considerations
for designing and running highly available "services" and not just
the systems infrastructure that supports those services. Providing
an overview of virtualization and cloud computing, it supplies a
detailed look at availability, redundancy, fault tolerance, and
security. It also stresses the importance of human factors. The
book starts off by providing an availability primer and detailing
the reasons why you need to be concerned with high availability.
Next, it outlines the theory of reliability and availability and
the elements of actual practices in this high availability (HA)
area, including Service Level Agreements (SLAs) and Change
Management. Examining what the major hardware and software vendors
have to offer in the HA world, the book considers the ubiquitous
world of clouds and virtualization as well as the availability
considerations they present. The book examines high availability
concepts and architectures such as reliability, availability, and
serviceability (RAS); clusters; grids; and redundant arrays of
independent disks (RAID) storage. It also covers the role of
security in providing high availability, cluster offerings,
emergent Linux clusters, online transaction processing (OLTP), and
relational databases.
