Red Hat

I worked at Red Hat, the world's leading provider of open source software solutions. I was part of the Nordic Consulting team, responsible for supporting customers to install, manage and use Red Hat infrastructure software.
I helped customers to run their Red Hat servers and have latest Linux features there. For example centralized management, automated deployment, virtualization, high availability, storage servers, load balancing. And of course many other services at top of Enterprise Linux.

For the past 20 years, Red Hat's open source software development model has produced high-performing, cost-effective solutions. Red Hat model mirrors the highly interconnected world we live in — where ideas and information can be shared worldwide in seconds. Today, more than 90% of Fortune 500 companies rely on Red Hat. Red Hat offer the only fully open technology stack, from operating system to middleware, storage to cloud and virtualization solutions. Red Hat also provides a variety of services, including award-winning support, consulting and training.
