C4: Container, Code, Cloud & Context
Designing intelligent systems, one layer at a time. ~ Nithin Mohan T K
Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, as with the electricity grid.
Cloud computing is a natural evolution of the widespread adoption of virtualization, Service-oriented architecture and utility computing. Details are abstracted from consumers, who no longer have need for expertise in, or control over, the technology infrastructure “in the cloud” that supports them.[1] Cloud computing describes a new supplement, consumption, and delivery model for IT services based on the Internet, and it typically involves over-the-Internet provision of dynamically scalable and often virtualized resources.[2][3] It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.[4] This frequently takes the form of web-based tools or applications that users can access and use through a web browser as if it were a program installed locally on their…
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
Running production workloads on Amazon EKS demands more than basic health checks. After managing dozens of Kubernetes clusters across various industries, I’ve learned that the difference between a resilient system and a fragile one often comes down to how deeply you can see into your infrastructure. This guide shares the observability patterns and CDK-based automation… Continue reading
The Evolution of .NET Deployment on AWS After two decades of building enterprise applications, I’ve witnessed the transformation of deployment practices from manual FTP uploads to sophisticated CI/CD pipelines. When AWS introduced their native DevOps toolchain, it fundamentally changed how we approach .NET application delivery. The integration between CodeCommit, CodeBuild, CodePipeline, and ECR creates a… Continue reading
Introduction: AWS re:Invent 2023 delivered transformative announcements for enterprise AI adoption, with Amazon Bedrock reaching general availability and Amazon Q emerging as AWS’s answer to AI-powered enterprise assistance. These services represent AWS’s strategic vision for making generative AI accessible, secure, and enterprise-ready. After integrating Bedrock into production workloads, I’ve found its model-agnostic approach and native… Continue reading
After two decades of managing cloud infrastructure across enterprises of all sizes, I’ve witnessed the evolution of Infrastructure as Code from simple shell scripts to sophisticated declarative frameworks. AWS Cloud Development Kit (CDK) represents a paradigm shift that fundamentally changes how we think about infrastructure provisioning. Rather than wrestling with YAML or JSON templates, CDK… 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
In the fast-paced world of technology, ensuring the reliability of services is paramount for businesses to thrive. Site Reliability Engineering (SRE) has emerged as a discipline that combines software engineering and systems administration to create scalable and highly reliable software systems. In the Azure cloud environment, Azure Kubernetes Service (AKS) plays a pivotal role in… Continue reading
As the world of software development continues to evolve, the need for robust infrastructures and efficient monitoring systems cannot be overemphasized. Whether you are an engineer, a site reliability engineer (SRE), or an IT manager, the need to harness the power of tools like Amazon Web Services (AWS), Elastic Kubernetes Service (EKS), Kubernetes, Terraform, and… Continue reading
In Azure, a landing zone is a pre-configured environment that provides a baseline for hosting workloads. It helps organizations establish a secure, scalable, and well-managed environment for their applications and services. A landing zone typically includes a set of Azure resources such as networks, storage accounts, virtual machines, and security controls. Implementing a landing zone… Continue reading
