Spring Cloud Stream Processors And Scripted Deployments With Spring Cloud Data Flow

Islands In The Stream. Not just a Country classic, they’re also a fact of life for data streaming apps — sending data in different directions depending on your processing logic. Implementing these forks/splits/channels is easy in Spring Cloud Data Flow for Kubernetes once you know how. Ben Wilcock (@benbravo73) takes you through an example step by step, starting with the code and finishing with the configuration and deployment. All in under 7 minutes!

Announcing Spring Cloud Data Flow for Kubernetes

Spring Cloud Data Flow first emerged in 2015 as an evolution of the innovative Spring XD. Since then, hundreds of organizations such as CoreLogic have adopted this open source technology, which is available on Cloud Foundry and Kubernetes. Generally available today, Spring Cloud Data Flow for Kubernetes addresses the needs of streaming and batch processing in the enterprise. This new offering is only available through the VMware Spring Runtime subscription.

Gardener, SAP's Kubernetes-as-a-service open source project, is moving its logging stack to Loki

Kristian Zhelyazkov is a developer at SAP working on Gardener, the SAP-driven Kubernetes-as-a-service open source project. In this guest blog post, he explains why the project is moving its logging stack to Loki.

Managing Docker Logs with ELK and Fluentd

This article provides an overview of managing and analyzing Docker logs and explores some of the complexities that may arise when looking through the log data. We will go through the default logging approach, as well as look at some more advanced configurations that will make diagnosing issues in your Docker-hosted applications much easier going forward.

Crafting Kubernetes Custom Controllers With Angela Chin

Custom controllers and custom resource definitions are all the rage in Kubernetes today! In conjunction, they allow users to extend the Kubernetes API and introduce additional features. In this session, we’ll explore both custom resource definitions and custom controllers by trying out popular projects that allow us to craft a new controller from scratch! Angela Chin is a Senior Engineer at VMware, working on Tanzu Application Service (for both VMs and Kubernetes!).

A Look at the New Calico eBPF Dataplane

Calico was designed from the ground up with a pluggable dataplane architecture. The Calico 3.13 release introduced an exciting new eBPF (extended Berkeley Packet Filter) dataplane targeted at those ready to adopt newer kernel versions and wanting to push the Linux kernel’s latest networking capabilities to the limit.

SUSE Acquires Rancher Labs: Is the Cloud Native Promise Under Threat from Consolidation?

When SUSE, the world’s largest independent open source company, announced its acquisition of Rancher Labs in early July 2020, the industry took notice. Clearly, the Kubernetes management industry is very much alive. But, the merger also raised the question of what this means for users? After all, a key value proposition of cloud native technologies, like SUSE, is that they are modular, interoperable, and flexible.

Kubernetes observability tutorial: Monitoring application performance with Elastic APM

This post is the third in our Kubernetes observability tutorial series, where we explore how you can monitor all aspects of your applications running in Kubernetes, including: We’ll discuss using Elastic Observability to perform application performance monitoring (APM) with the Elastic APM.

Kubernetes Log Management: The Basics

Log messages help us to understand data flow through applications, as well as spot when and where errors are occurring. There are a lot of resources for how to store and view logs for applications running on traditional services, but Kubernetes breaks the existing model by running many applications per server and abstracting away most of the maintenance for your applications. In this blog post, we focus on log management for applications running in Kubernetes by reviewing the following topics.

Instant scale up for even the most dynamic ECS clusters

One of the key features of Ocean by Spot is a “headroom” feature, the ability to maintain a dynamic buffer of spare capacity for immediate scale-up. Ocean continuously predicts which workloads are most likely to require scale-up and adjusts headroom in line with this prediction to enable immediate scheduling of new tasks, without waiting for infrastructure provisioning. This shortens the time to execution for these workloads and dramatically speeds up the scale-up process.
