C4: Container, Code, Cloud & Context
Designing intelligent systems, one layer at a time. ~ Nithin Mohan T K
After two decades of managing containerized workloads across production environments, I’ve come to appreciate that the difference between a good Kubernetes deployment and a great one often comes down to how intelligently it responds to changing demand. Horizontal Pod Autoscaling (HPA) represents one of those fundamental capabilities that separates reactive operations from proactive infrastructure management.… Continue reading
Introduction: Amazon Elastic Kubernetes Service (EKS) simplifies the process of deploying, managing, and scaling containerized applications using Kubernetes on AWS. In this guide, we’ll explore how to provision an AWS EKS cluster using Terraform, an Infrastructure as Code (IaC) tool. We’ll cover essential concepts, Terraform configurations, and provide hands-on examples to help you get started… Continue reading
Introduction: Amazon Elastic Container Registry (ECR) is a fully managed container registry service provided by AWS. It enables developers to store, manage, and deploy Docker container images securely. In this guide, we’ll explore how to provision a new AWS ECR using Terraform, a popular Infrastructure as Code (IaC) tool. We’ll cover not only the steps… Continue reading
GitOps has emerged as a powerful paradigm for managing Kubernetes clusters and deploying applications. Two popular tools for implementing GitOps in Kubernetes are Flux and ArgoCD. Both tools have similar functionalities, but they differ in terms of their architecture, ease of use, and integration with cloud platforms like Azure AKS. In this blog, we will… Continue reading
Docker has revolutionized the world of software development, packaging, and deployment. The platform has enabled developers to create portable and consistent environments for their applications, making it easier to move code from one environment to another. Docker has also improved collaboration among developers and operations teams, as it enables everyone to work in the same… Continue reading
Docker is a popular platform for developing, packaging, and deploying applications. In the previous blog, we provided an introduction to Docker and containers, including their benefits and architecture. In this article, we’ll dive deeper into Docker, exploring Dockerfiles, Docker commands, and OCI specifications. Dockerfiles Dockerfiles are text files that contain instructions for building Docker images.… Continue reading
Containers are a popular technology for developing and deploying applications. They provide an isolated runtime environment that runs an application and its dependencies, making it easier to package, deploy, and manage the application. Docker is a platform for managing containers that has become very popular in recent years. In this article, we’ll provide an introduction… Continue reading
What is the difference between Kubernates and Service Fabric? It is a common question today among most of the business stakeholders, infrastructure specialists, and information technology architects. To answer in simpler words, quoting from this Reddit log : Kubernetes manage/orchestrate containers and applications within. ServiceFabric is a… Continue reading
I will start with history:Â Sometime around 2016, Microsoft launched an IaaS service called Azure Container Service a.k.an ACS serves as a bridge between Azure Ecosystem and existing container ecosystem being used widely by the developer community around the world. It helps as a gateway for infrastructure engineers and developers to manage underlying infrastructure such as… Continue reading
When you work with Cloud Computing or normal Scalable highly available applications you would normally hear two terminologies called Scale Out and Scale Up or often called as Horizontal Scaling and Vertical Scaling. I thought about covering basics and provide more clarity for developers and IT specialists. What is Scalability? Scalability is the capability of… Continue reading
