What can WebAssembly do for your Application Security and Extensibility

Years ago when I heard WebAssembly (Wasm) for the first time, I was intrigued. The fact that I can write code in Rust or C++ and have it running in a browser blew my mind immediately.

Tetrate launches Industry-first exam for Certified Istio Administrator

Enterprises are increasing their investments in digital transformation and in hiring the right talent to accelerate the journey. According to the 2020 open source jobs report from Linux Foundation, 52% of hiring managers are more likely to hire someone with a certification, up from 47% two years ago. Not so surprisingly, 93% of hiring managers report difficulty finding sufficient talent. Tetrate today announced the public availability of its exam for Certified Istio Administrator by Tetrate (CIAT) that evaluates skill, knowledge, and ability to perform Istio service mesh installation and configuration as well as configure traffic management, resilience and fault injection, and use security features of the Istio service mesh. This follows the February launch of the free training and certification course on Istio Fundamentals. Over 600 IT professionals have taken the training since then.

Tuya Smart’s Implementation of an Enterprise-level Istio in Production

An Istio use case of Tuya Smart.

Background

As the most active service mesh project at present, Istio provides numerous capabilities, including traffic management, security, and observability. Each capability is necessary for the management, operation, and maintenance of services. Istio’s extensive capabilities also bring certain challenges to the operation and maintenance of complex systems. In terms of its capabilities and future scalability, Istio reimagines service management, bringing about new opportunities along with challenges.

Tuya Smart currently uses Istio control plane version 1.5.0 for its front-end business, allowing access to the Istio control plane by over 700 services and 1,100 pod instances that are responsible for the traffic control and capacity support of the largest business cluster at the front-end of Tuya Smart.

End-User Tracing in a SkyWalking-Observed Browser

Web application performance affects the retention rate of users. If a page load time is too long, the user will give up. So we need to monitor the web application to understand performance and ensure that servers are stable, available and healthy. Apache SkyWalking is an application performance monitoring (APM) tool designed especially for cloud native and container-based architectures. Its skywalking-client-js is a lightweight, client-side JavaScript exception, performance and tracing library.
