I joined alter way in October 2016 for a purely technical role and a bit of a career shift towards networking and infrastructure. There I had the opportunity to rework many core systems and processes that helped the company grow in many ways. -On the networking side I helped put in production and operate our anti-ddos systems and reworked then maintained our bgp routers configurations for that purpose. I also lead the one year long upgrade project of our core network to 100G technologies based on Arista hardware. The core switches relied on OSPF as underlay and VxLAN as overlay. The routers also used OSPF as IGP. +On the networking side I helped put in production and operate our anti-ddos systems and reworked then maintained our bgp routers configurations for that purpose.

The routers were from Juniper and also used OSPF as IGP. -I implemented a virtualized pre-production of all the core devices in gns3 in order to automate the configuration management and test protocol interactions. Automation was first implemented with ansible but was soon replaced with a perl tool for generating and deploying the configurations. Ansible was too slow and we went from a dozen minutes to redeploy the entire backbone configurations down to a few seconds. +I implemented a virtualized pre-production of all the core devices in gns3 in order to automate the configuration management and test protocols interactions. Automation was first implemented with ansible but was soon replaced with a perl tool for generating and deploying the configurations because Ansible was too slow: we went from a dozen minutes to redeploy the entire backbone configurations down to a few seconds. -I also maintained and improved the way we operate our netapp storage clusters by automating processes and standardizing configurations. This allowed to rework the way we operate our PRA to reduce downtimes and allow for proper testing of the PRA before we need it. I also handled the hardware refreshes and the storage migrations. +I also maintained and improved the way we operate our netapp storage clusters by automating processes and standardizing configurations. I reworked the way we operate our PRA to reduce downtimes and allow for proper testing of the PRA before we need it. I also handled the upgrades, hardware refreshes and the storage migrations. On the systems side I redesigned the backup platform from the ground up with a mix of bareos and docker on debian. The platform's usage was of about 120TB and managed to backup everything incrementaly every night on just two big storage servers. -On a final note I had the opportunity to work on the redesign of how we deploy and operate alter way's public cloud offering (networking, storage and compute). I worked on a mix of hardware virtualization and kubernetes and automated most things ansible and terraform. I also had my first experiences with cloud system administration while helping clients moving to hybrid architecture (a balanced mix of on premise and in the cloud). +On a final note I had the opportunity to redesign how we deploy and operate alter way's public cloud offering (networking, storage and compute). I worked on a mix of hardware virtualization and kubernetes and automated most things with ansible and terraform. I also had my first experiences with cloud system administration while helping clients moving to hybrid architecture (a balanced mix of on premise and in the cloud). It has been a great and diversified experience, but after five years I felt my future was not necessarily in an architect role with purely on premise hardware and decided to move on. |
