As scalability becomes increasingly non-negotiable and more applications are built with containers, the open-source software Kubernetes has become an appreciated one-stop shop for developing and running applications. Kubernetes helps manage multiple containers across different systems, allowing you to scale them with ease. It provides access to plugins and extensions to improve management and security. And with the ability to use cloud-based solutions, increases the portability of your applications. Use this course to learn about application scaling and the benefits of containerized applications and cloud computing. Examine the key components within a Kubernetes deployment. As you progress, run and configure clusters; use kubectl, ConfigMaps, probes, taints, and tolerations; and finally, set up autoscaling and configure a Kubernetes multi-pod deployment. Upon completion, you'll be able to scale applications using Kubernetes.

Kubernetes package management allows developers to easily package, configure, and deploy applications and services onto clusters. Package managers maintain the application lifecycle, enabling you to optimize several tasks. Learning how to utilize these resources will improve your ability to scale Kubernetes applications and services. Use this course to gain a theoretical and practical understanding of the importance of package management. Examine how each of the major cloud platforms manages Kubernetes services for continuous delivery. And explore what's on offer through the various Kubernetes package managers. On a practical front, learn how to manage Kubernetes YAML manifests. Work with Helm, creating Helm charts, chart hooks, and Kubernetes ConfigMaps and Secrets. And lastly, deploy a multi-pod application using Helm. Upon completion, you'll be able to conduct Kubernetes package management in the most viable way.

Logging and monitoring should be a central part of any good DevOps process, including those associated with cloud-native application development and scaling. While traditional logging and monitoring tools aren't designed for cloud-native environments, there are other solutions. Use this course to comprehend how cloud platforms have changed the nature of logging and monitoring. Learn how Google Cloud Operations for Google Kubernetes Engine (GKE), Amazon Elastic Kubernetes Services (EKS), Microsoft Azure Kubernetes Services (AKS), and Kubernetes handle logging and monitoring. On a practical front, use klog to generate log messages, debug issues with Kubernetes audit logs, pull events using kubectl, use Fluentd to log information, Elasticsearch to monitor your Kubernetes applications, and Kibana to log and collect time series analytics. When you're done, you'll be able to implement logging and monitoring into your Kubernetes application development processes.
