Training in Hungarian
Summary of the course
Length of the course: 4 days
This course gives participants a strong knowledge of Kubernetes including how to deploy and operate containerized applications.
The significance of Kubernetes lies in that it provides an elegant answer to problems that have posed a serious challenge to developers and operators over the past decade. With the advent of Docker, containerization has been a huge turning point in the move to unify development, testing, and operating environments. Container technology soon became popular with IT professionals, but running thousands of containers on hundreds of servers is a huge challenge. The Kubernetes provides an answer to this problem.
Dávid Szabó, PhD
Dávid has recently finished his PhD in telecommunication at the Budapest University of Technology. Since he also finished the Innovation & Entrepreneurship Doctoral School organized by EIT Digital, he decided to switch into business and co-found LeanNet together with Péter. Dávid has extensive knowledge in the field of cloud native applications. He was involved in several Hungarian and international projects and supported the design and implementation process of such applications including software architecture, CICD pipelines and cloud infrastructure creation.
Péter Megyesi, PhD
Péter has BSc and MSc in electrical engineering, and a PhD in computer science, all received at the Budapest University of Technology and Economics. He also graduated in the EIT Digital Doctoral School on Innovation & Entrepreneurship. In 2018 he co-founded LeanNet with Dávid Szabó, a deep tech company focused on Cloud Native technologies. LeanNet was acquired by adesso SE in 2020, so now he works as a Cloud Native architect at adesso Hungary. Péter is a regular presenter at local IT conferences and meetups in related topics. He also serves as an instructor for various Cloud Native trainings, such as Kubernetes, Docker, Azure cloud and modern CI/CD.

Who is it for
Recommended for infrastructure/operation engineers and developers who are interested in the DevOps concept. In addition, those who work as designers or decision-makers and would like to gain more insight into the opportunities offered by Kubernetes are also welcome to apply.
The training requires only general web networking knowledge (eg TCP / IP protocol stack, HTTP), basic programming knowledge (in any language) and some basic Linux knowledge (Bash).
