Create a URL shortener API with Kotlin, the micro-framework Ktor and PostgreSQL (Part 1/2)

The source code for this post can be found on this github repo Ktor is a brand new micro-framework created by the Jetbrains team and running over the JVM. Jetbrains are the authors of Kotlin - the official language for Android, and Intellij - one of the popular IDE. I personally have +4 years of experience using Spring and I wanted to give a try to Ktor which seems promising. Creating a URL shortener is a good way to start.

AI Meets Kubernetes: Install JupyterHub with Rancher

AI and Machine Learning are becoming critical differentiators in the technology landscape. By their nature, AI and ML are computation hungry workloads. They require best-in-class distributed computing environments to thrive. AI and ML present a perfect use case for Kubernetes, the distributed computing platform engineered at Google to run their massive workloads.

What is Amazon ECS?

Many companies are moving their infrastructure and web applications to the cloud. Along with moving to the cloud, organizations are finding new ways to remain agile and nimble, especially when it comes to software. By utilizing Amazon AWS and Amazon ECS, companies are decoupling their monolithic applications and taking advantage of microservice architecture.

Transforming Telematics with Kubernetes and Rancher

Norwegian leader in fleet management, equipment and vehicle tracking, ABAX is one of Europe’s fastest-growing technology businesses. The company provides sophisticated fleet tracking, electronic mileage logs and equipment and vehicle control systems to more than 26,500 customers. ABAX manages over 250,000 active subscriptions that connect a variety of vehicles and industrial equipment subscriptions.

Monitoring in the Kubernetes era

Container technologies have taken the infrastructure world by storm. Ideal for microservice architectures and environments that scale rapidly or have frequent releases, containers have seen a rapid increase in usage in recent years. But adopting Docker, containerd, or other container runtimes introduces significant complexity in terms of orchestration. That’s where Kubernetes comes into play.

Monitoring Kubernetes performance metrics

As explained in Part 1 of this series, monitoring a Kubernetes environment requires a different approach than monitoring VM-based workloads or even unorchestrated containers. The good news is that Kubernetes is built around objects such as Deployments and DaemonSets, which provide long-lived abstractions on top of dynamic container workloads.

Collecting metrics with built-in Kubernetes monitoring tools

In the previous post in this series, we dug into the data you should track so you can properly monitor your Kubernetes cluster. Next, you will learn how you can start inspecting your Kubernetes metrics and logs using free, open source tools. In this post we’ll cover several ways of retrieving and viewing observability data from your Kubernetes cluster.

Kubernetes Master Class: Getting started with Pod Security Policies and best practices in Production

Kubernetes Pod Security Policies (PSPs) is an enforcement mechanism to ensure that Pods run only with the appropriate privileges and can solely access the appropriate resources. You can leverage them as a threat prevention mechanism by controlling Pod creation, and limiting the capabilities available to specific users, groups, or applications.

Running Containers in AWS with Rancher

This blog will examine how Rancher improves the life of DevOps teams already invested in AWS’s Elastic Kubernetes Service (EKS) but looking to run workloads on-prem, with other cloud providers or, increasingly, at the edge. By reading this blog you will also discover how Rancher helps you escape the undeniable attractions of a vendor monoculture while lowering costs and mitigating risk.
