The book is Alfresco For Administrators by Vandana Pal (Senior Consultant at Cignex Datamatics) and it will be released on March 2016.
I worked on this project contributing during the review process adding my comments for all the chapters together with the author.
The book will show you an overview of all the main topics that you need to know for managing an Alfresco installation.
It will go in deep with some tasks that you should know how to do for your daily job when you are managing an Alfresco instance, such as: installation, configuration, tuning, enabling and disabling components / functionalities and so on.
Hope all my comments helped to improve the overall quality of the book :)
I would like to thank Packt Publishing for this opportunity of being part of another important project about Alfresco!
