It was my privilege working with my technical reviewer, Ranga Rao Karanam. I would like to thank my mentors (Karthic Sundararaj, VP IT Architecture Emirates Group IT; and Rajesh R.V, Chief Architect Emirates Group IT), teachers, friends, and my extended family for their support in me to reach this stage in my career, with words of encouragement and wealth of knowledge at all times. I would like to thank my entire Packt team (Chaitanya, Zeeyan, and Ruvika) for their support and this opportunity. Lastly, I would like to thank everyone who stood besides me during this entire journey.
