Use Tetrate’s Open Source Istio Cost Analyzer to Optimize Your Cloud Egress Costs

Who Is This For?

You should read this if you run Kubernetes and/or Istio on a public cloud, and you care about your cloud bill. Cloud providers charge money for data egress, including data leaving one availability zone destined for another. If your Kubernetes deployments span availability zones, you are likely being charged for egress between internal components. Even if you don’t run Kubernetes/Istio, you’ll still run into cross-zone data egress costs, which this article will help you understand and minimize.

Pinpoint Service Mesh Critical Performance Impact by using eBPF

Introducing performance analysis in production with SkyWalking Rover.

Background

Apache SkyWalking observes metrics, logs, traces, and events for services deployed into the service mesh. When troubleshooting, SkyWalking error analysis can be an invaluable tool helping to pinpoint where an error occurred. However, performance problems are more difficult: It’s often impossible to locate the root cause of performance problems with pre-existing observation data. To move beyond the status quo, dynamic debugging and troubleshooting are essential service performance tools. In this article, we’ll discuss how to use eBPF technology to improve the profiling feature in SkyWalking and analyze the performance impact in the service mesh.

Introduction to Service Mesh

Service mesh is an infrastructure layer between application components and the network via a proxy. These app components are often microservices, but any workload from serverless containers to traditional n-tier applications in VMs or on bare metal can participate in a mesh. Rather than each component communicating directly with other components over the network, the proxies mediate that communication. These proxies form the data plane, providing many capabilities for implementing security and traffic policy and producing telemetry about the services the proxies are deployed with.

ISTIO: How to enforce egress traffic using Istio’s authorization policies

An Istio Egress gateway is just another envoy instance similar to the Ingress but with the purpose to control outbound traffic. Istio uses ingress and egress gateways to configure load balancers executing at the edge of a service mesh. An ingress gateway allows you to define entry points into the mesh that all incoming traffic flows through. Egress gateway is a symmetrical concept; it defines exit points from the mesh. Egress gateways allow you to apply Istio features, for example, monitoring and route rules, to traffic exiting the mesh.

NIST Standards for Zero Trust: the SP 800-204 Series

Introduction

This is the second installment in a two-part series on NIST standards for zero trust security. The first installment covers NIST Special Publication (SP) 800-207, which lays the groundwork for zero trust principles for the enterprise, but makes no specific implementation recommendations. 

The follow-up series is made up of four special publications: SP 800-204, SP 800-204A, 800-204B, and 800-204C. This series is co-authored with NIST by Tetrate founding engineer Zack Butcher and takes up where SP 800-207 leaves off.

This series provides security strategies for microservices applications. It mostly focuses on communications between services and between services and a control plane, as described below, under the header Threat Background. In this article, we’ll present an overview of the most important concepts, best practices, and specific deployment recommendations in each of the four papers of the SP 800-204 series:

Istio component ports and functions in detail

In my last blog, I gave you a detailed overview of the traffic in the Istio data plane, but the data plane does not exist in isolation. This article will show you the ports and their usages for each component of both the control plane and data plane in Istio, which will help you understand the relationship between these flows and troubleshoot them.

Envoy API Gateway: The Gateway to a New Frontier

Today, the Envoy community announced an exciting new project: Envoy Gateway. The project unites industry leaders to streamline the benefits of application gateways powered by Envoy. This approach allows Envoy Gateway to immediately establish a solid foundation for rapid innovation. The project will provide a suite of services to manage an Envoy Proxy fleet, drive adoption through ease of use, and support a multitude of use cases through well-defined extension mechanisms.
