DevOps Online Course Details: DevOps is a new term coming from a mixture of two major related trends. The first was called “agile infrastructure” or “agile operations”; it sprang from applying Agile and Lean approaches to operations. The second is a much-expanded understanding of the value of collaboration between development and operations staff throughout all stages of the development lifecycle when creating and operating a service, and how important operations has become in our increasingly service-oriented world (cf. Operations: The New Secret Sauce).
One definition Jez Humble proposed is that DevOps is ” a cross-disciplinary community of practice dedicated to the study of building, evolving and operating rapidly-changing resilient systems at scale.”

Why Should One Take DevOps?
- Shorten Production Cycles: Siloes development and operations teams extend the production cycle unnecessarily. It becomes difficult for both teams to collaborate on the processes required to get the software operational.
- Increase Deployment Success Rates: Programming errors are one of the leading reasons why a deployment fails. The frequent release of code occasioned with the DevOps approach ensures problem detection at an earlier stage.
- Improved Collaboration and Communication: DevOps has revolutionized software development culture. This is because when all stakeholder teams take part in the development process, they focus on a common goal instead of working with different objectives. More synergy improves communication.
- Increased Efficiency Through Automation: Continuous integration reduces manual processes in developing and testing. Specific tasks in the development process cannot be automated. DevOps focusses the developers’developers’ attention on those tasks, leaving the other tasks to tools that can accelerate the development,
- Increase Product Quality: The DevOps process builds quality into the development process, thereby reducing instances of unplanned work. A focus on security during the designing and development stage minimizes the need to remedy security issues later on, thus saving time. And it was freeing more resources to other work.

Learn DevOps – The Complete Kubernetes Course
This course is available on Udemy in 700 rupees. This course will help you comprehend how to deploy and maintain your applications on Kubernetes. If you are interested DevOps, this is a technology you need to learn. Kubernetes has caught a lot of popularity lately, and it is a well-sought skill by companies. You can containerize applications using Docker. You can then use those containers on your servers, but there’s no chance you can manage those efficiently without extra management software, which is mandatory for you to have. Kubernetes is an orchestrator for the containers that will schedule, create,& manage your containers on a cluster of servers. Kubernetes can run on-premise on a single machine or thousands of machines.
What you’ll Learn in DevOps
- You will be able to install and configure Kubernetes (on your laptop/desktop or production-grade cluster on AWS)
- You will be able to use Docker Client (with Kubernetes), kubeadm, kops, or minikube to setup your cluster
- You will be able to run stateless and stateful applications on Kubernetes
- You will be able to use Healthchecks, Secrets, ConfigMaps, placement strategies using Node/Pod affinity / anti-affinity
- You will be able to use StatefulSets to deploy a Cassandra cluster on Kubernetes
- You will be able to add users, set quotas/limits, do node maintenance, setup monitoring
- You will be able to use Volumes to provide persistence to your containers
- You will be able to scale your apps using metrics
- You will be able to package applications with Helm and write your Helm charts for your applications
- You will be able to automatically build and deploy your own Helm Charts using Jenkins
- You will be able to install and use tubeless to run functions (Serverless) on Kubernetes
- You will be able to install and use Istio to deploy a service mesh on Kubernetes
- You will be able to continuously Develop using Skaffold.
DevOps Online Course Eligibility Criteria
- There is no prior understanding needed, but a dev/ops/Linux/network background will have an edge.
