I only acquired the qualification because it was necessary for my work, so I felt that I needed additional learning, so I purchased the course and am studying it. It is easy to understand because it explains the architecture based on pictures and explains the overall structure flow from the perspective of an infrastructure manager. I also liked the part where the instructor appropriately introduced the management tools that he actually uses, not just the theoretical part. It was a satisfactory course because the instructor delivered the difficulties and opinions he encountered in the field as news. I look forward to your continued support.
