Why does Kubernetes need a unified application model? It would be the final piece needed to run a seamless deployment model. By Joab Jackson.
Multi-Cluster service mesh failover and fallback routing
Posted on September 10, 2020, Level intermediate Resource Length medium
In this blog series, we will dig into specific challenge areas for multi-cluster Kubernetes and service mesh architecture, considerations and approaches in solving them. In our first post, we looked at service discovery and in this post we'll look at failover and fallback routing across multiple clusters. By Denis Jannot.
Building your own serverless functions with k3s and OpenFaaS on Raspberry Pi
Posted on September 6, 2020, Level intermediate Resource Length long
In recent years, lots of new programming paradigms have emerged – going from monolithic architectures towards microservices and now serverless functions. As a result, less code needs to be deployed, and updating an application becomes easier and faster as only a part has to be built and deployed. By Andreas Muttscheller.
Tutorial: Deploying TensorFlow models at the edge with NVIDIA Jetson Nano and K3s
Posted on September 5, 2020, Level intermediate Resource Length long
Janakiram MSV put together this tutorial about TensorFlow models. We will explore the idea of running TensorFlow models as microservices at the edge. Jetson Nano, a powerful edge computing device will run the K3s distribution from Rancher Labs. It can be a single node K3s cluster or join an existing K3s cluster just as an agent.

Marc Andreessen famously said, "Software is eating the world." Dr. Steve Willmott subsequently retorted, "APIs are eating software." This is because API based architectures are enabling companies to get away from monolithic architectures and move to microservices. Innovative, disruptive companies like Netflix, Airbnb, Uber, Square, and Slack all build their infrastructure and technology using APIs. By bluematador.com.
