Adapters approach in 2005 as a solution for dealing with the problems encountered with traditional n-tier applications, coupling, and code entanglement Service Discovery: 1 You should get the following message: How to tame event-driven microservices “Microservices”, “Serverless computing”, “Nanoservices”, “Containerized” — you could fill a whole blog post just with these overused It is a great and humble feeling to release my very first book “Designing Microservices Platforms with NATS” on 19th November 2021 (first edition) Designing microservices platforms with nats 1 But there are couple of issues here Microservices can subscribe to certain work of a workflow and get tasks via some kind of queue Welcome to the Official NATS Documentation Read More » NATS broker instance 'Core NATS' is the set of core NATS functionalities and qualities of service NATS Messaging vs REST Performance Comparison Job category Azure Kubernetes Service offers fully managed Kubernetes clusters for deployment, scaling, and management of containerized applications Micro on NATS: Blog post by Asim Aslam detailing how/why Micro uses NATS You can read it through Amazon, Barnes and Nobel In this example, we use NATS Steraming Server as the event streaming system to build event-driven Microservices The application reconstructs an entity’s current state Introduction This reference guide is the first in a four-part series about designing, building, and deploying microservices I see several test levels for it: Unit testing - one container format; Integration testing - several container formats; e2e via GUI For more information see https://nats • Message/event persistence • At-least-once-delivery • Publisher rate limiting • Rate matching/limiting per subscriber • Historical message
