Software Architecture Bootcamp is your hands-on "field
manual" for becoming a great software architect! This
hands-on "field manual" gives developers the essential skills
they need to survive and thrive as software architects!
You’ll find insightful, real-world coverage of everything from
design patterns to prototyping, business case development
to leadership. Leading software architects Raphael Malveau
and Thomas Mowbray share profound insights and practical
solutions for all the key challenges of architectures using
objects, components, and distributed Internet computing,
showing how to avoid time-consuming pitfalls and costly
errors. You’ll master proven methods for:
Identifying the best architectural model for any project
Executing heavyweight or lightweight approaches to
software architecture Addressing scalability and long-term
business flexibility Making the most of abstraction,
refactoring, and architectural prototyping Leveraging
superior design patterns to improve your implementations
With hands-on exercises, real-life war stories, and a take-
no-prisoners attitude, Software Architect Bootcamp won’t
just help you become a great software architect: it’ll help
you become a true technical leader of your organization.

Preface
Software architecture is an emerging discipline and an exciting career path for software
professionals. We encourage both new and experienced practitioners to read this book as
an aid to becoming better software architects. You may have noticed that most software
books today do not say much about software architecture. Here, in this volume, we've
concentrated the knowledge that you need to be the most effective architect possible.
As co-authors, we have lived through the experience of graduating from "member of
technical staff" developers to becoming practicing software architects at the most senior
levels of our respective companies. We are technical people, not managers, and we enjoy
the technical nature of our work. We enjoy parity of salary and benefits with the senior
managers at our respective firms. In other words, we are none-the-worse-for-wear as a
consequence of choosing a software architecture career. We think that many of our
readers would like to gain from our experience. Hence this book.
This is more than a book about software architecture. It is a field manual that can train
you. We choose the pseudomilitary style, because it embodies an essential attitude. As a
software architect, you need many survival skills— some technical, some political, some
personal. While neither author has mili- tary experience, we have seen software
architecture become a battleground in many ways. It is a battleground of ideas, as
developers compete to forward their own concepts. It is a battleground for control of key
design decisions that may be overruled by managers or developers, perhaps covertly. It is
a battleground with many risks, since architects are responsible for a much wider range of
technical and process risks than most managers or individual developers.
If you are a practicing software architect, we know that you are a busy professional. After
buying this book, we would suggest that you peruse the table of contents and the index
for topics that are new to you. Focus on those sections first. When you have time, we
suggest that you attempt a cover-to-cover read-through, to familiarize yourself with all of
the covered topics and terminology.
If you are new to architecture and want to become a software architect, we suggest that
you do a cover-to-cover read-through beginning with the first chapter. Work the exercises
provided, which will add an experiential learning element to your experience base.
