The NATS Java library with support for JetStream has just been released! JetStream allows you to persist streams of messages, allows consumers to either subscribe in real time or to access the messages at a later time with the added flexibility to choose from where in the stream you want to start receiving messages. You can start reading from the stream at a specific point in time or start at a specific message sequence number. Read more...

Introducing NATS CLI Historically NATS did not have a clear obvious place to go for a CLI tool, users had various example applications that had to build and run manually. These tools were primarily examples of using the APIs rather than full UX CLI experience. As part of the NATS 2.2.0 release that introduced JetStream and its administration needs, we took the opportunity to build a full CLI tool for users and administrators alike. Read more...

A few months ago, Header support was added to NATS Server. With the release of the 2.10.0 Java client , Headers are completely supported. NATS Headers are analogous to http request Headers and you can leverage them for the same type of things, for example, to pass information like security, request, transaction or state information. In Java terms, it’s analogous to a map of type Map<String, List<String>> In fact, that’s exactly what is used for the backing data structure in the Headers object. Read more...

Overview NATS 2.2 is the largest feature release since version 2.0. The 2.2 release provides highly scalable, highly performant, secure and easy-to-use next generation streaming in the form of JetStream, allows remote access via websockets, has simplified NATS account management, and provides native MQTT support built into the server. These features further enables NATS toward our goal of securely democratizing streams and services for the hyperconnected world we live in. Read more...

The NATS Server can make good use of TLS for securing various connections, including some modes where NATS servers talk directly to each other. When you configure the server to verify the certificate of a peer, you provide a path to a Certificate Authority bundle file, to act as a trust anchor. So far, so normal. In environments such as Kubernetes, it’s common for a certificate management process to create a Kubernetes secret, containing a key, a certificate, and a copy of the issuer’s certificate as ca.

Overview At Synadia we have the goal of unifying all cloud, edge, and IoT communications. We guide companies in their journey from where they are today toward efficiently operating a secure and resilient modern distributed communications system and leverage the NATS.io project to get them there. Derek Collison, creator of NATS, founded Synadia which stewards the NATS project. We see users deploy NATS in ways that fit into a few buckets - a single cluster k8s deployment, a cluster of NATS servers in the cloud, on VMs, or on bare metal. Read more...

On April 16th, 2020 we had our first NATS conference, NATS Connect!.

Once again, Dale Bingham of Cingulara adds to his series on using NATS for a service mesh type of implementations in your applications by contributing his thoughts on load balancing on APIs and services when you have more than one service answering requests or responding to events. Read the full article Using NATS to Implement Service Mesh Functionality Part 4: Load Balancing and Routing Control . More About the Author Dale Bingham is the CTO of Cingulara. Read more...

In this, the 3rd part of Dale Bingham’s series on “Using NATS to Implement Service Mesh Functionality”, Dale speaks about how to have similar service mesh benefits, usage and design when using the NATS messaging system as your communication backbone. As with anything dealing with software engineering, there are pros and cons to deciding on languages, infrastructure, and design models. It is always great to have alternatives and new ways of looking to solve problems. Read more...
