Amazon ECS Vs. EKS Vs. Fargate: The Complete Comparison

Amazon Web Services (AWS) provides more than 200 services. Among those, Amazon Elastic Compute Service (ECS), Elastic Kubernetes Service (EKS), and AWS Fargate help deploy and manage containers. Choosing between these services can be challenging. They seem similar on the surface (and are all popular). But each offers unique benefits and limitations. In this guide, we compare the three services, discussing the best use cases for each, and helping you choose the best fit for your business.

Enlightning - Instant Observability: Exploring the Magic of Pixie

Pixie is an open source observability tool for Kubernetes applications. Pixie automatically collects telemetry data, including full-body requests, resource and network metrics, application profiles, and more. Using Pixie, developers can view the high-level state of their cluster (service maps, cluster resources, application traffic) and also drill down into more detailed views (pod state, flame graphs) without having to modify or redeploy their code.

Kubernetes Node Vs. Pod Vs. Cluster: What's The Difference?

Kubernetes is increasingly becoming the standard way to deploy, run, and maintain cloud-native applications that run inside containers. Kubernetes (K8s) automates most container management tasks, empowering engineers to manage high-performing, modern applications at scale. Meanwhile, several surveys, including those from VMware and Gartner, suggest that inadequate expertise with Kubernetes has held back organizations from fully adopting containerization.

What are microservices, and how do they relate to DevOps architecture

Microservices are an architectural style that structures an application as a collection of small, loosely coupled, and independently deployable services. Each service in a microservices architecture focuses on a specific business function and communicates with other services through well-defined APIs, typically over HTTP/REST or messaging queues.

Beyond Booleans: How Feature Flags and OpenFeature Can Level Up Your Next Project

Feature flags are more than just on/off switches! In this meetup, we will be exploring a variety of creative ways to use feature flags in your projects. From making safer deployments to running A/B tests and gradually rolling out features, you'll see how versatile and powerful feature flags can be. We'll also introduce the OpenFeature standard, which makes implementing feature flags more streamlined than ever. Whether you're new to feature flags or looking to get more out of them, this session will provide practical insights and tips to help you take your projects to the next level.
