Hello everyone, My name is Julien. I'm an IT Engineer specialized in IT Network. I decided after few years in the Network environment to jump into the virtual World with VMware in April 2019. I have been working since in the server virtualization bringing my knowledge and implementing the Virtualization of the Network. In November 2019 I passed my first VMware Certification: VMware Certified Professional - Network Virtualization 2019 (VCP-NV 2019) I would like to share my experience and knowledge by publishing some blogs on this web site. I'm glad that my colleague and mentor Eric Krejci allows me to post and share experiences on this web site. I hope you will enjoy it and learn with me. Cordially yours, Julien
