My suggestion would be similar to what a few have advised - submit another article. You can give it an SEO-friendly title like 'What are the training modules for DevOps' and in the summary mention, "This article is an insight into the training program for DevOps based on a personal experience". In the intro part of your article, mention briefly what DevOps is about (with different text from your first article) and a link to your earlier article. Then talk about the career scope/job prospects, the importance of getting the right training for it and then move on to all the training aspects which you experienced, where you underwent this training (if it is not required that you must keep this confidential), etc.
