Role: Solutions Architect Network InfrastructureProject: Datacenter RefreshAfter numerous major outages on the European network infrastructure which had a severe impact on the business continuity. PVH launched a program to revamp the data center infrastructure. The scope of the project was to establish a new network infrastructure based on the latest technologies on networking and security and migrate network services, compute, and SAP systems to a new datacenter facility. My primary focus was to analyze the existing technology environment, define implementation and migration strategy and design the best technology solutions in response to business problems or requests. In addition to my primary role, I have also been involved in a number of projects to refresh and improve edge and remote access connectivityAchievements:- Defined network datacentre blueprint for the European Datacenters.- Deployed VXLAN fabric with Cisco DCNM integration.- Developed detailed migration and implementation plans for; o Legacy proxy to Checkpoint with SSL inspection and URL filtering o Routing migration from legacy to new infrastructure o Network services e.q. Netscaler, F5, Infoblox o IPsec VPN migration from Cisco to Checkpoint o Migration from classic Cisco ASA to Cisco FMC- AWS Cloud integration.- Deployed a geo-redundant active / active remote access VPN for +2500 associates. - Developed Corporate Meraki design for the European offices with VPN exclusion.Keywords; Checkpoint R80, DCNM, Infoblox, Anyconnect, IPsec, Meraki, AWS, Umbrella
