After 2 years of marathon run I was able to complete the self-published book on Oracle Commerce (ATG & Endeca) which covers both the commerce product installation, configuration, concepts, architecture, and some of the open source tools that you can use such as Vagrant, Elasticsearch, Kibana, Logstash, and Splunk.
This book is absolutely free as my contribution to the industry, colleagues, and the commerce community.
The motivation behind this book is “no books written on the subject” and “the goal to make the journey of beginners as painless as possible”.
Hope this will be useful to not just the beginners but also those who embrace open source tools and technologies along with branded products and services.
Also, if you do not own an apple device you can download the PDF version of book from Slideshare using this link
