Pushing the boundaries from the edge to the cloud at ultra-low latency: how NASCAR uses NATS to deliver real-time racing data to broadcasters, racing teams, and fans. Distributing live telemetry data NASCAR’s NextGen cars feature a host of changes including being fitted with sensors generating 60 data points hundreds of times per second for the duration of the race. This telemetry data is transmitted over UHF radio waves to the NASCAR mobile data center (literally a data center in a semi-truck trailer that goes to each track venue), where it is then ingested and retransmitted both to the racing teams and broadcasters on-site at the track but also to the AWS cloud where it is both stored for historical analysis and re-distributed in real-time to the team’s back offices and to racing fans.

Starting in 2018 with .NET Core 2.1 , the .NET platform began to receive serious performance improvements in every major release. This excited many .NET developers, who have been enjoying faster and more efficient runtimes just by upgrading their project targets with every new .NET release. In 2021, .NET 6 became the first LTS release under Microsoft’s new .NET and .NET Core Support Policy . The original NATS .NET client, called NATS. Read more...

As the Kubernetes ecosystem continues to grow, installing NATS via Helm has become a very popular method. The NATS 0.x series of the Helm Chart was initially released in 2020, a full year before JetStream was even available in the NATS Server. The past 3 years have taught us that it is important to support all of the extensibility options possible in Kubernetes resources - custom Image Registries, ConfigMaps, TLS Secrets, Volumes and Mounts, Init Containers, and more.

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...
