Marius Voila — SRE (Site Reliability Engineer)

I'm a Linux sysadmin with over 14 years of experience, and doing DevOps before I even knew DevOps was a thing. I'm specialising in deployments, cloud computing, load balancing, scaling and performance tuning, as well as developing disaster-recovery best practices and server security audits. Personality profile: I like to think out of the box and ask the hard questions. I assume nothing and always try to build context and a sense of the big picture in everything I do. I enjoy extreme complexity and digging into, and making myself master of, complex IT systems. The devil is in the details. Because of the amount of importance I place on accuracy of information, context and detail, I will often be the go-to guy for understanding how something -actually- works. In my communications, I always provide context and prefer giving too much information, that too little. My Passions: Infrastructure automation and containerization: Kubernetes, CoreOS, Docker, TræfIk, Chef Metrics and monitoring: Datadog, Graphite, InfluxDB, Grafana. Prometheus, Sensu, Monitor all the things Specialties: • Linux, UNIX, and the BSDs • Xen Paravirtualization • OpenStack • Networking, architecture and security • MySQL setup, load balancing, and clustering • Apache and Nginx web servers • IPSec, OpenVPN, and SSH tunneling • Firewalls including those based upon Netfilter, IPFW, and PF • Experience in system design from the ground up • Software Defined Networking – Juniper Contrail • Software Defined Storage - Ceph • DevOps and continuous delivery • Monitoring large scale infrastructure • Containers (Docker/Mesos) • ElasticSearch, Logstash, Kibana • Kubernetes • Much more, just ask me.
