An Istio-based Traffic Management Use Case of eBay

As a centralized cloud platform, Kubernetes manages multiple heterogeneous applications, including online services, big data, and backend searches. The number of clusters reaches up to the hundreds. In large clusters, thousands of microservices and hundreds of thousands of pods are run in a single cluster. Needless to say, different types of applications have different traffic management needs. The question then arises: how do we address these different needs with a centralized model? In fact, this is the biggest challenge that eBay has been seeking to tackle for years.

TSB CI/CD Pipeline on Gitlab deploying application in AWS

As code gets signed off by a developer, it goes to the infrastructure teams that deploy it in the dev/test environment and then validate it via a number of tests. The developer’s skill set usually doesn’t include knowledge of Kubernetes, service mesh parameters, or Ingress gateways. Beyond knowledge, there is usually enterprise grade separation of roles: the developer shouldn’t have access to the network configuration, unnecessary monitoring tools, and certainly not security objects such as certificates.

Using Traefik Ingress Controller with Istio Service Mesh

The Istio service mesh comes with its own ingress, but we see customers with requirements to use a non-Istio ingress all the time. Previously, we’ve covered integrating NGINX with Istio. Recently we’ve been working with customers that are using Traefik ingress. With some slight adjustments to the approach we suggested previously, we at Tetrate learned how to implement Traefik as the ingress gateway to your Istio Service Mesh. This article will show you how.

What’s new in Istio 1.9

On February 9, Istio announced the release of Istio 1.9. In this release, we can see the wider adoption of VMs into the service mesh, and even better VM support, cert issuance to VMs, and health checking for the workload entry. Istio’s latest releases, 1.7 and 1.8, made a lot of progress toward making VMs first-class workloads in the mesh, and cert issuance has been the final gap to close.

Introducing GetIstio: the easiest way to get started with Istio

 

Istio is one of the most popular and fast-growing open source projects in the cloud native world;  while this growth speaks volumes about the value users get from Istio, ease of getting started with and it’s rapid release cadence can be a challenge for many users. Combine that with managing several different versions of Istio clusters at the same time, manually configuring CA certificates for cloud platforms etc – it could get really daunting pretty quickly.

SkyWalking 8.4 provides infrastructure monitoring for VMs

Apache SkyWalking– the APM tool for distributed systems–  has historically focused on providing observability around tracing and metrics, but service performance is often affected by the host. The newest release, SkyWalking 8.4.0, introduces a new feature for monitoring virtual machines. Users can easily detect possible problems from the dashboard– for example, when CPU usage is overloaded, when there’s not enough memory or disk space, or when the network status is unhealthy, etc.
