深入分析Istio Ambient 和 Sidecar 模式下的网络路径和配置 | Deep Dive Into Istio Network Flows and Configurations for the Coexistence of Ambient and Sidecar - Huailong Zhang, Intel & Yuxing Zeng, Alibaba Cloud Istio是全球最流行的服务网格。作为服务网格的经典实现，Sidecar模式显然存在一些缺点，比如资源利用问题和每个Pod引起的大量重复配置。因此，社区希望通过引入一种称为Ambient的新模式来解决这些问题。自Istio 1.17发布以来，我们已经对Istio Ambient模式的架构和更多细节有了一瞥。然而，Sidecar模式仍然是社区推荐的默认安装模式。毫无疑问，在未来相当长的时间里，Ambient模式和Sidecar模式将共存。 在这个主题中，我们将分享： 为什么引入了Istio Ambient模式以及它与Sidecar架构有何不同。 介绍Istio Ambient Mesh的架构，深入分析了在真实流量场景中同时启用Ambient和Sidecar模式时的网络流量和xds配置。 Istio is the most popular Service Mesh all over the world. As the classic implementation for Service Mesh, Sidecar mode obviously has drawbacks, such as resource utilization issues and large number of duplicated configurations caused by sidecar per pod. Therefore, the community is expecting to resolve these issues by importing a new mode called Ambient. And we have got a glance of the architecture and more details of Istio Ambient mode since the release of Istio 1.17. However, Sidecar mode is still the default installation mode recommended by the community. It's no doubt that the Ambient and Sidecar modes will coexist for a long time in the future. In this topic, we will share: 1. Why Istio Ambient mode was introduced and how it differs from the Sidecar architecture. 2. Introduction to the architecture of Istio Ambient Mesh, a deep analysis of network flows and xds configuration with both Ambient and Sidecar mode enabled in real traffic scenarios.
