Overview
Kubernetes is an open-source orchestration system for automating management, placement, scaling and routing of containers. It provides an API to control how and where the containers would run. Docker is also an open-source container-file format for automating the deployment of applications as portable, self-sufficient containers that can run in the cloud or on-premises. Together, Kubernetes and Docker have become hugely popular among developers, especially in the DevOps world.
Both Docker and Kubernetes are huge open-source technologies, largely written in the Go programming language, that use human-readable YAML files to specify application stacks and their deployment.
Cognixia brings to you a unique training covering basic to advanced-level concepts of Docker and Kubernetes. The training offers an engaging and immersive learning experience for participants where they can take advantage of connecting with an industry expert trainer, develop their competencies to meet industry and organizational standards, as well as learn about real-world best practices.

Course Description
Gartner predicts that by 2023, 70% of the organizations will be running three or more containerized applications in production. Containers, Kubernetes and Microservices application patterns are the three main drivers of enterprise IT innovation and digital transformation. The number of organizations that have containerized more than half of their applications is currently growing at a pace of close to 22%. Docker and Kubernetes are two of the most popular tools bridging the gap between Development and Operations today, and are shaping the future of business architecture. The future outlook for these tools is very positive, and with time, their demand and applications are going to grow manifold.
Docker and Kubernetes s one of the top 10 fastest rising tech skills today, according to Indeed. During the four-year period between October 2015 to October 2019, the share of Kubernetes jobs per million grew by 2141.03% and the share of Kubernetes job searches increased by 2125.66%. The top five tech roles related to Docker and Kubernetes are DevOps engineer, Software engineer, Software architect, Cloud engineer and Full stack developer.
