solution transformation to a platform such as Azure.
Modernizing Legacy Applications to Microsoft Azure
uncovers potential scenarios and provides choices,
methodologies, techniques, and prospective possibilities
for transitioning from legacy applications to the
Microsoft Azure environment. You'll start by understanding
the legacy systems and the main concerns regarding
migration. Then, you'll investigate why distributed
architectures are compelling and the various components of
the Azure platform needed during migration. After that,
you'll explore the approaches to modernizing legacy
applications and the Rs of modernizing (i.e., rehost,
refactor, rearchitect, and retire). You'll also learn
about integration approaches and potential pitfalls. By
the end of this book, you'll be well equipped to modernize
your legacy workloads while being aware of pitfalls and
best practices.
