Several years ago the realization of the need of spreading DevOps skills and knowledge got Proidea and us, Allegro into launching the first edition of the Atmosphere. The conference appeared to be important for Polish IT and software development communities, so we decided to continue our cooperation and to travel with the conference within Poland. Allegro stands for the biggest e-commerce site in CE Europe but also for advances in technologies spanning key areas: Big Data, Security, Deployment and Mobile as well as agile software development practices.
