Leveraging Istio for Creating API Tests Low Effort API Testing for Microservices | CONFIDENTIAL • What has changed? – Migration to microservices triggering need for extensive API tests • Problem: – Creating auto-generated from end-to-end tests – Significantly reduced time and cost for API testing for microservices architectures with Istio – Fewer failures higher up the test pyramid as a result of improved

master's degree in computer science from Columbia University. Title : Behavior-driven Tests for Microservices-based Algo Trading System Summary : Introduction : This poster will introduce a test framework framework we use at Bloomberg to enable behavior-based tests in natural language style for a microservices-based algo trading system that our engineering team is responsible for. Relevance : For our

22 1. Fork and clone the repositories: microservices-demo and front-end You will need a GitHub account for this step. Before you can modify the microservices demo application, The Sock Shop, fork the https://github.com/microservices-demo/front-end - This is the front-end service of the Sock Shop application. You will update the color the buttons in this example. • https://github.com/microservices-demo/microservices-demo Container Image Using an editor of your choice, open manifests/front-end-dep.yaml, from the microservices-demo repo you forked and update the image line. Change it from: image: weaveworksdemos/front-end

ServiceComb-based Microservice Practice of MedSci Miao Yanjie Chief Architect, MedSci Service Mesh-based Microservices and Those Based on a Traditional Architecture Two network platforms, covering all users in improving report processing efficiency by more than 80% by using new technologies such as microservices and AI. iDrugSafety Competitiveness Analysis Quality Cost Specifications System Functions evolved. • Multiple languages are supported. The hybrid deployment of Service Mesh-based microservices and those bases on a traditional architecture is supported. • There are many successful commercial
