 Kubernetes 

==========

Kubernetes, often shortened to K8s, is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. 

It's designed to handle complex, distributed applications, especially those using microservices architectures, by providing tools for automation, service discovery, load balancing, and self-healing. 


Here's a more detailed breakdown:


Core Functionality:

Container Orchestration:

Kubernetes manages containers, which are isolated packages containing an application and its dependencies, allowing them to run consistently across different environments. 


Automation:

It automates many of the manual processes involved in deploying, scaling, and managing applications, such as rolling out updates, scaling up or down based on demand, and self-healing by restarting failed containers. 


Scalability:

Kubernetes allows applications to scale up or down easily based on resource utilization, ensuring optimal performance and resource allocation. 


Portability:

Kubernetes can run on various infrastructure, including bare metal servers, virtual machines, and public or private clouds, making applications highly portable. 


Self-Healing:

Kubernetes monitors the health of containers and automatically restarts failed ones, ensuring high availability and minimal downtime. 


Key Concepts:


Pods: The smallest deployable units in Kubernetes, grouping one or more containers that share resources. 


Services: An abstraction that exposes an application running on a set of pods, providing a stable endpoint for accessing it. 


Deployments: Manage the desired state of applications, allowing for updates and scaling. 


Nodes: The worker machines in a Kubernetes cluster, where applications run. 


Clusters: A collection of nodes managed by Kubernetes. 


Benefits:

Reduced Operational Overhead:

Kubernetes automates many tasks, freeing up developers and operations teams to focus on other priorities. 


Improved Resource Utilization:

By efficiently managing resources and scaling applications, Kubernetes helps optimize resource usage. 


Increased Reliability and Availability:

Kubernetes' self-healing capabilities and automated management ensure high availability and minimize downtime. 


Enhanced Scalability:

Kubernetes makes it easy to scale applications up or down as needed, adapting to changing demands. 


Kubernetes: Revolutionizing Industries with Powerful Features

Kubernetes is a powerful platform for managing containerized applications, offering a wide range of features and benefits for modern cloud-native development.

Top 10 high-level EC2 scenario-based questions to challenge your AWS & DevOps skills

 Here are 10 high-level EC2 scenario-based questions to challenge your AWS & DevOps skills 1. Your EC2 instance is running but you can’t connect via SSH. What troubleshooting steps will you take?  Check Security Group inbound rules (port 22 open to your IP).  Verify Network ACLs (NACLs not blocking inbound/outbound).  Confirm instance’s Public IP / Elastic IP.  Validate Key Pair and correct permissions on .pem.  Ensure SSM Agent is installed (Session Manager can help).  Check system logs on the console for OS-level issues. 2. You terminated an EC2 instance by mistake. How can you prevent this in the future? Enable Termination Protection in EC2 settings. Use IAM permissions to restrict TerminateInstances. Tag critical instances and set resource policies. 3. Your EC2 instance needs to access an S3 bucket securely. What’s the best way to configure this? Best practice: Attach an IAM Role with least privilege policy to the EC2 instance. Avoid hardcoding...

GitOps-Driven Management of VKS Clusters: Enabling GitOps on VCF 9.0 (Part 03)

  GitOps-Driven Management of VKS Clusters: Enabling GitOps on VCF 9.0 (Part 03) In the Part-02 blog, we walked through the process of deploying an Argo CD instance within a vSphere Namespace on  VMware Cloud Foundation (VCF) 9.0 , enabling a GitOps-based approach to manage Kubernetes workloads in a vSphere environment. With Argo CD successfully installed, we now have a powerful toolset to drive declarative infrastructure and application delivery. In this blog post, we’ll take the next step by demonstrating how to  provision and manage VKS clusters  directly through the Argo CD  UI and CLI . This allows us to fully operationalise GitOps within the private cloud, delivering consistency, scalability, and automation across the Kubernetes lifecycle. Importance of Managing the Kubernetes Cluster with a Gitops Approach Adopting a GitOps-based approach for managing Kubernetes clusters enables declarative, version-controlled, and automated operations by leveraging Git a...
