The REST to NATS proxy project sohlich/nats-proxy is the micro framework that provides a bridge between HTTP and NATS. To introduce the problem, we first compare the HTTP and NATS communication models. The table below represents the matching of HTTP and NATS concepts and what do they provide. HTTP NATS Request/Response Request/Reply synchronous communication Websocket Publish/Subscribe real-time asynchronous communication As you can see, the NATS provides both synchronous and asynchronous communication between clients.

In the context of a submittal to the Samsung Maker’s Against Drought Challenge (more on that here ) extended hackathon, my team has developed a partial solution to the very serious California drought crisis. I say partial since this problem is so vast that many solutions are required to operate collaboratively to fully solve it. The solution utilizes physical water system monitoring and control with Samsung ARTIK 10 IoT modules, and a Particle Photon module running the arduino-nats NATS client. Read more...

In this post we’re going to discuss using Micro on NATS . It includes discussion around service discovery, synchronous and asynchronous communication for microservices. If you would like to learn more about Micro first, check out the blog post detailing the toolkit here. Let’s get down to business. What is NATS? NATS is an open source cloud native messaging system or more simply a message bus. NATS was created by Derek Collison, the founder of Apcera. Read more...

At Sendify we’ve been using nats as a simple and effective means of communicating between our backend services. I came across Nats a few years ago when building a relatively small microservice backed system and it worked wonderfully. With that experience, I introduced it to Sendify this year as the main nervous system for inter-service communication. Our system is mainly processing api requests to various freight carriers based on user searches though we’re also building integration for public api access as well. Read more...

A few weeks ago, the Apcera Platform gained a new service gateway. The new NATS service gateway will allow Apcera Platform users to quickly give their apps a NATS server - without sacrificing security or reliability. In this post, we’re going to demonstrate a simple server that broadcasts data to some clients over NATS. As a distributed messaging system, NATS is lightweight, high performance, and secure - making it ideal for modern architectures. Read more...

Hello everyone. It’s been a great start to 2016, and we didn’t want to go too long without hosting another NATS meetup. Now that we are well past the holiday hangover, and into the conference and event season, before things get too busy we wanted to invite everyone out to our offices in the heart of San Francisco at 140 New Montgomery Street. On March 22nd, we will be hosting a NATS Meetup (RSVP here if you can make it! Read more...

As some of you may have noted, last week a new version of the nats-top monitor for NATS has been made available for download on Github: https://github.com/nats-io/nats-top/releases/tag/v0.2.0 If you’re looking for a bit more information about nats-top, my talk last fall at a NATS meetup on nats-top is here: As nats-top is a top like monitoring tool, so developers who prefer terminal tools such as this will be very comfortable with it.

Recently I decided to see how easy it would be to create an [AWS Lambda] (https://aws.amazon.com/lambda/) equivalent within the [Apcera] (https://www.apcera.com/) trusted cloud platform and use [NATS] (https://www.nats.io) as an event source for triggering function invocations. This blog entry gives an outline of AWS Lambda, the approach I took to get a first implementation up and running and offers up some thoughts on possible futures. What is AWS Lambda? AWS Lambda (λ) is computation without computers, or at least without the explicit notion of computer machines, virtual or physical hosts; in many ways, the ultimate evolution of Platform As A Service and Microservice architectures.

Aditiva recently started to use NATS inside solutions for financial institutions that are our customers. In this blog entry, you can learn more about Aditiva, some of our products, and how we use NATS in delivering these solutions for financial institutions. Aditiva provides a High Performance Financial Transactional Platform (Aditiva EFT),that integrates Financial Institutions’ Core Systems, with 3rd party networks. For example, Financial Institution Customers execute different Financial Transactions using Plastic Cards from ATMs and POS networks; these generate ISO 8583 transaction messages, that are captured and routed to authorization services provided by the Aditiva EFT Platform installed on Financial Institution premises or on the Issuer side, and it is managed and supported by Aditiva.

I’ve attended SCALE a few times in the past, and have always been impressed with the event that the SCALE team puts on each year; but I hadn’t attended in a few years, and it has gone from strength to strength in that time! There are more booths, training sessions, breakout talks / BOF’s, and more developers and interesting open source community members to hear from and collaborate with. As a result, SCALE was held for the first time at the more spacious Pasadena Convention Center: Read more...
