如何高效可靠进行事件监听,k8s 客户端工具包 client-go 提供了一个通用的 informer 包,通过 informer,可以方便和高效的进行 controller 开发。
Kubernetes 安全风险加固手册
随着 Kubernetes 的广泛应用,安全风险也逐渐凸显出来。本文将从 Cloud、Cluster、Container 角度出发,以一种由下至上的方式,列举 Kubernetes 的安全风险,并提供相应的加固建议。
Kafka on Kubernetes: Reloaded for fault tolerance
Coban - Grab’s real-time data streaming platform - has been operating Kafka on Kubernetes with Strimzi in production for about two years. In a previous article (Zero trust with Kafka), we explained how we leveraged Strimzi to enhance the security of our data streaming offering.
In this article, we are going to describe how we improved the fault tolerance of our initial design, to the point where we no longer need to intervene if a Kafka broker is unexpectedly terminated.
pincompute: A Kubernetes Backed General Purpose Compute Platform for Pinterest
Modern compute platforms are foundational to accelerating innovation and running applications more efficiently. At Pinterest, we are evolving our compute platform to provide an application-centric and fully managed compute API for the 90th percentile of use cases. This will accelerate innovation through platform agility, scalability, and a reduced cost of keeping systems up to date, and will improve efficiency by running our users’ applications on Kubernetes-based compute. We refer to this next generation compute platform as PinCompute, and our multi-year vision is for PinCompute to run the most mission critical applications and services at Pinterest.
PinCompute aligns with the Platform as a Service (PaaS) cloud computing model, in that it abstracts away the undifferentiated heavy lifting of managing infrastructure and Kubernetes and enables users to focus on the unique aspects of their applications. PinCompute evolves Pinterest architecture with cloud-native principles, including containers, microservices, and service mesh, reduces the cost of keeping systems up to date by providing and managing immutable infrastructure, operating system upgrades, and graviton instances, and delivers costs savings by applying enhanced scheduling capabilities to large multi-tenant Kubernetes clusters, including oversubscription, bin packing, resource tiering, and trough usage.
In this article, we discuss the PinCompute primitives, architecture, control plane and data plane capabilities, and showcase the value that PinCompute has delivered for innovation and efficiency at Pinterest.
