Introduction

A series of books “IT Architecture from A to Z” is an author’s attempt to collect, summarize and systematize his accumulated experience and knowledge in IT.

A series of books “IT Architecture from A to Z” – Green Book

“IT Architecture from A to Z: Theoretical Basis” is the first book of the “IT Architecture from A to Z” series which contains the theoretical basis of planning, building and maintaining IT architecture, Project management, IT services, etc. It is used as a source of proven practical materials and recommendations of standards and practices. It is a revised, amended and updated edition of “IT Architecture: a Practical Guide from A to Z”.

A series of books “IT Architecture from A to Z” – Blue Book

“IT Architecture from A to Z: A Complete Solution” is the second book of the “IT Architecture from A to Z” series which contains detailed technical information and practical examples of implementing IT solutions based on the fundamentals of the theory described in the first book. As examples, I considered Windows 10/2016 based solutions, as well as complex solutions on monitoring, managing and configuring Microsoft System Center 2016, Microsoft SharePoint Server 2016, project management solutions in Microsoft Project Server 2016, Exchange 2016, Skype for Business 2015 solutions, functionality of Direct Access 2016, Hyper-V, DFS и File Server, RDS etc. I presented the detailed requirements and examples of system assurance estimates as well as the power capacity calculations and costing solutions. The author selects solutions that are the most suitable for performing the objectives set, or have been practical for him. It is a revised, amended and updated edition of “IT Architecture: A Practical Guide from A to Z”.

A series of books “IT Architecture from A to Z” – Grey book

“IT Architecture from A to Z: Documentation Templates” contains the set of documentation templates and examples, required for daily IT routine. It is used as a source of proven practical materials and recommendations of standards and practices.

A series of books “IT Architecture from A to Z” – Yellow book

“IT Architecture from A to Z: Solutions Catalog” describes the possibilities of various IT solutions, analysis and comparison of functionalities. Over a hundred solutions have been tested or practically used so far.

A series of books “IT Architecture from A to Z” – Red book

“IT Architecture from A to Z: Alternative Solutions” contains detailed technical information and practical examples of carrying out the IT solutions based on the theory, described in “IT Architecture from A to Z: Theoretical Basis”. As examples, the author uses solutions whose priority selection criterion is “zero value”. The IT infrastructure and components described in the “Blue book” are taken as a basic solution.

A series of books “IT Architecture from A to Z” – Black book

“IT Architecture from A to Z: Cloud solution” contains the detailed technical information and practical examples of carrying out the IT solutions based on the theory described in “IT Architecture from A to Z: Theoretical Basis”. The “cloud” solutions are used as examples where possible.

The Objectives of thee Book

The objectives of the book is to help the specialists, IT managers and directors to build the architecture of the enterprise, arrange management processes, calculate the costs of implementation and maintain the IT infrastructure, select the optimal architecture solution, from both a business and IT perspective. The book will help arrange communication between business and IT, allowing them to communicate in the same “language”. The material presented in the book is not sufficient for a detailed study of all aspects of IT operations, but it is enough to understand the links of various aspects and give a direction for organization development in general and particularly in IT.

The book is not a mandatory guide for selecting a product or a solution, and presents the author’s views.

The material is presented in a logical order, supplemented with theoretical information and illustrative examples of implementation. That makes the guide useful for methodical study of all aspects of IT operations, as well as using it as a handbook when working with particular systems.

Scope covered by the Book

This book is the first one of the series “IT Architecture from A to Z” and a Russian manual, containing and harnessing theoretical knowledge of enterprise architecture, project management, informational security, IT service and audit arrangement and management. The book also considers the order of their practical use, allowing complete provision of organizational needs for building and managing IT architecture and IT infrastructure. Extensive material gives systematic description of the state of the modern IT company and demonstrates the main models and approaches of creating an IT strategy, risk management, IT service control, risk analysis and quality management, IT audits, and integration and interaction of various approaches and methods. The book is for the general public and will be useful to:

•Top-managers, IT curators, CIO’s of the large and middle companies since it provides better understanding of TOGAF based Enterprise Architecture, the IT role and involvement ИТ in business and indicators of financial investments distribution in IT services. Business representatives will be able to understand the general aspects of the functioning of the IT infrastructure, technical terms, the fundamental differences between various architectural solutions, and principles of building and maintenance of technical solutions. The book allows you to create metrics and IT infrastructure effectiveness reports understandable by both parties.

•Heads of IT department, IT architects and middle managers, and project managers who need theoretical basis of IT service management (ITSM) using ITIL recommendations and practices, project integration management (PMI) in IT, Control Objectives for Information and Related Technologies (CobiT) and information security.

This book is not supposed to be used by small IT infrastructure since the cost of paper is higher than IT requirements. It will also be ineffective for large enterprises with corporate governance, as every direction is likely to be managed by the narrowly focused experts.

Special Thanks

I express my gratitude to my friends, teachers, managers and colleagues for their help in writing the book and their invaluable experience and knowledge obtained via communication with such people as Alexander Buslayev (“AIC Group”), Irshad Guliyev (“SINAM”), Fazil Mammadov (“ROTABANK”), Yana Khmelnitskaya and Karsten Stellner (“LFS Financial Systems GmbH”), Thomas Engelhardt (“Microfinance Bank of Azerbaijan”), Andrew Pospielovsky (“ACCESSBANK”) and Alan Crompton (“Baku European Games Operation Committee BEGOC 2015”).
