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 Staff II Technical Product Manager within the Cloud Services Business Unit (CSBU) at VMware. In this role, I function as a technical product expert for specific cloud provider solution areas (NSX Data Center, NSX ALB, etc.), design and develop technical sales and marketing collateral for new and existing technologies (demos, presentations, blogs, technical white papers, videos), work closely with the CSBU engineering team providing feedback on early engineer releases and feature implementations, and much more. Ping me if you want to know more (contact section below)!

I have 17+ years of diverse work experience in architecture, consulting, and service portfolio management, primarily focusing on virtualization and networking, but also automation and cloud-native applications lately.

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, 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).

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.
