Software Architecture is one of the important topics for software engineers, because many failures of software development projects are caused by inadequate design. Thus, it is essential to learn more about architectural issues in theory and practice. Interesting new books that have been published recently or in the near future could be very helpful
There is a constant tussle between following Agile techniques and still managing to do enterprise architecture.
