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:
• 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.

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.
11. 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.
12. Contd..
There are a number of reasons why you should consider backing up your
Kubernetes clusters.
First, you can restore your data easily if a failure occurs.
Second, you can use the Commvault Backup API to automate your
backups.
Third, you can create a daily backup schedule to ensure that your data is
backed up.
Fourth, you can restore your data from the Commvault Backup API.
13. Conclusion:
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.
