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 Infrastructure Business Group (CIBG) at VMware where I help to drive the vision and bring new capabilities to our products. In this role, I develop innovative solutions that enable cloud providers to deliver agile, robust, and flexible cloud services. I also function as a technical product expert for specific cloud provider solution areas (mainly around networking and security) and design and develop technical collateral for emerging and existing technologies (demos, presentations, blogs, technical white papers, videos).

Ping me if you want to know more (contact section below)!

I have 18+ years of diverse work experience in architecture, consulting, and technical product management, primarily focusing on virtualization and networking, but also automation and cloud-native applications.

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.
