Welcome to cloudmaniac.net! I started this blog in 2014 by myself, Romain Decker, mainly as a self-documentation exercise on my findings and a place to share my experience and write down thoughts on various technical challenges.

This blog is powered by Hugo and hosted on AWS services (Route53, CloudFront, S3, Lambda).


Romain Decker - VMworld 2018 I am currently working as a Principal Product Manager at Spectro Cloud. I have 18+ years of diverse work experience in architecture, consulting, and technical product management. Throughout my career, I have worked for a variety of organizations, including hosting companies, enterprises, EU institutions, and system integrators. More recently, I spent 8.5 years at VMware, working first as a Solutions Architect before focusing on Technical Product Management for the VMware Cloud Provider Program.

Romain Decker - SnowboardI constantly renew my technological background through experimentation. When I’m not working, experimenting with things in my lab, or spending time with my wonderful & lovely wife and my two boys, I enjoy activities such as snowboard, running, mountain-bike, or photography. If you’re interested or just curious, you can check some of my photos on my 500px account.

I hold numerous industry certifications, including VCDX-DCV (VMware Certified Design Expert for Data Center Virtualization) and VCDX-NV (VMware Certified Design Expert for Network Virtualization). Verify my digital credentials and badges on Credly.

My VCDX number is #120. You can find me among my peers on the official directory: Meet the VMware Certified Design Experts.

I’m also a VMware vExpert since 2014 and a vExpert NSX, which rewards my commitment to the community.
