We’re lucky to have partners and customers in healthcare and even luckier to have a team of highly skilled and talented software engineers. So when the challenge came along to build a meaningful demo for a Telehealth scenario, we couldn’t resist. No conversation on this topic would be complete without a sprinkle of AI or ML and so we posit that when used for good, these technologies can be applied to the preservation and quality of human life.

Data Synchronization Between Microservices With microservice architectures becoming the standard nowadays, it is a common need to extract data from your database to synchronize other downstream services. Consider a social network where you have a service that stores new posts in a MongoDB collection. You may want to notify other services when a post is created, perhaps so that you can save it on Redis for fast retrieval, or add it to Elastic for full text search queries. Read more...

k3s is a lightweight Kubernetes distribution suitable for IoT and edge computing environments. One component k3s leverages is KINE , which is a shim enabling the replacement of etcd with alternate storage backends originally targeting relational databases. In April 2022, the v0.9.0 release of KINE introduced native support for NATS as a backend. In June 2022, the k3s v1.23.7+k3s1 release included this KINE version making it possible for k3s deployments to connect to an existing NATS system. Read more...

Normally, the NATS maintainers do not publish a dedicated announcement for a patch release, but the 2.9.15 release of the NATS server has several significant stability and performance improvements worth highlighting, all driven by our new quality engineering process! 🥳 What does a patch release mean to NATS? And what are these new quality engineering processes? Release management At the beginning of 2023, the NATS maintainers drafted an end-to-end “release management” document which includes the policies and procedures used for each NATS server release, everything from initial scoping to communication of the release itself.

WunderGraph At WunderGraph, we’re building an infra-less cloud for developers, meaning that we free developers from dealing with infrastructure. We believe a developer doesn’t need to be proficient in deploying and maintaining infrastructure to build a global SaaS. WunderGraph is here to make our life easier (We use WunderGraph to build WunderGraph Cloud ). It allows you to integrate data sources of different types like REST, GraphQL, and Databases into a unified representation (the Virtual Graph) to make the work with your API dependencies a pleasant experience.

For those relatively new to NATS, it may come as a surprise that the NATS server has native support for WebSockets ! What this means in practice, is that the NATS server binary is able to support direct WebSocket connections from the browser (or other clients) using it as a transport layer for the NATS protocol rather than raw TCP packets. In addition to server-side support, there is an official nats. Read more...
