Introduction to Kubernets in Cloud Computing
- 2. Kubernetes – Intro.. ► Kubernetes is a free and open source technology for automating the deployment, scaling and management of containerized applications. ► It is being used by major cloud providers like Google, Microsoft, IBM and Alibaba to run their container-based workloads. ► So, what is Kubernetes and how it is different from other similar software?

- 3. The history of Kubernetes: Refreshscience.com • Kubernetes was first released in 2014 by Google. • The developers wanted to create a tool for automating the deployment, scaling and management of containerized applications. • Kubernetes has become one of the most popular open source projects because of its simplicity and easy integration with cloud computing services.
- 4. What is a container and why it is used in Kubernetes? ► A container is nothing but a virtual machine that is running on a single physical server. ► It is just a virtual machine that has been configured to provide a complete operating environment for your container. ► A container provides a complete operating system and all the applications and libraries that are required to run a software application. ► So, if you want to build a software application, you need to install the dependencies in the container, and if you want to run the application then you need to install the containers in the host machine. ► This is the basic concept of a container and Kubernetes uses this concept to manage the applications.

- 57. Features of Kubernetes: ► Automation: ► One of the main reasons for using Kubernetes is to automate the process of creating, deploying, managing and monitoring the containers. ► This allows the developers to focus on their primary task, which is writing the code. Kubernetes does all the work for them. ► This automation also allows the developers to scale their applications as per their needs. ► Kubernetes supports many tools that make it easy for the developers to deploy, scale and manage the applications.

- 58. Features of Kubernetes: ► Scalability: ► Kubernetes can easily be scaled up or down to meet the requirements of a cloud-based service provider. ► Kubernetes supports horizontal scaling, which means that you can add more machines to a cluster to increase the number of containers. ► The Kubernetes architecture is highly scalable.

- 59. Features of Kubernetes: ► Cost savings: ► Kubernetes is a free and open source project. It is being used by many cloud providers to run their container-based workloads. ► As it is a free tool, you don’t have to pay for the licensing fees of the software. So, you can save a lot of money by using the free version of the tool. Refreshscience.com
- 60. Kubernetes security and observability ► Kubernetes is one of the most popular container management systems available today. ► The rise of container technology has increased the demand for containers within organizations. ► Because of this, Kubernetes adoption is on the rise, and so is the demand for Kubernetes security. ► For example, companies like Google, Netflix, and Amazon are using Kubernetes extensively. ► In fact, Kubernetes is the leading platform for container orchestration and management. As such, there are a number of tools that you can use to monitor Kubernetes security. Refreshscience.com
- 61. Best open source monitoring tools for Kubernetes ► There are a number of open source tools that you can use to monitor and secure Kubernetes. Here are some of the most popular tools for doing so: 1. Heptio Ark ► The Heptio Ark is a cloud-native monitoring solution for Kubernetes. The Ark is built around the idea of containers, and as such, it monitors and reports on container health. The Ark also provides a number of features to help you troubleshoot issues. ► The Ark is one of the most popular tools for monitoring and securing Kubernetes. 2. New Relic ► New Relic is a commercial service that offers a lot of features to help you troubleshoot issues with your Kubernetes deployments. New Relic can help you monitor and report on performance issues and can even alert you if a Kubernetes cluster is under stress. Refreshscience.com
- 62. Best open source monitoring tools for Kubernetes 3. Prometheus ► Prometheus is an open source service for monitoring and reporting on Kubernetes. It provides a number of features that you can use to monitor and report on Kubernetes clusters. ► Prometheus is an open source service for monitoring and reporting on Kubernetes. 4.CloudWatch ► CloudWatch is a commercial service from Amazon that helps you monitor and report on your Kubernetes clusters. 5.Grafana ► Grafana is an open source tool that helps you monitor and report on your Kubernetes clusters. 6.Alertmanager ► Alertmanager is an open source tool that helps you monitor and manage alerts for your Kubernetes clusters.

- 63. Commvault Kubernetes backup ► One of the most important ways to secure your Kubernetes clusters is to back up your data. ► Kubernetes is a highly-available system, which means that it’s not very easy to recover your data if a failure occurs. ► For example, if you’re using Kubernetes on Google Cloud, you can use the Google Kubernetes Engine to create a cluster. If you’re using Kubernetes on AWS, you can use the AWS Fargate service to create a cluster. ► If you’re using a public cloud, you can use CloudBackup to backup your Kubernetes cluster. ► However, if you’re using Kubernetes in your own data center, then you can use Commvault to backup your Kubernetes clusters. ► Commvault is an open source product that is used to backup and restore your Kubernetes clusters.
