mqtt.org VS emissary

MQTT (optional): If you're aiming for advanced customization, familiarity with MQTT (a lightweight messaging protocol) will be beneficial for communicating between the toy and the server.

The MQTT protocol is widely used in IoT applications because of its simplicity and ability to connect different data sources to applications using a publish/subscribe model. While many MQTT brokers support persistent sessions and can store message history as long as an MQTT client is not available, there may be cases where data needs to be stored for a longer period. In such cases, it is recommended to use a time series database. There are many options available, but if you need to store unstructured data such as images, sensor data, or Protobuf messages, consider using ReductStore. It is a time series database specifically designed for storing large amounts of blob data and optimized for IoT and edge computing.

https://mqtt.org is more popular, but its more complex. You will unlikely write your own mqtt while you can easily write own stomp broker.

I wanted to share my latest package (published on NuGet) implementing the MQTT v5 protocol.

I jumped onto https://mqtt.org/ to try to answer my usual use-case question about non-Kafka messaging, which is: "Do the messages get saved anywhere so you can come back and read them later?" Still not entirely sure about it.

But I did see:

    This is why MQTT has 3 defined quality of service levels: 0 - at most once, 1- at least once, 2 - exactly once

rumqttd is a high performance, embeddable MQTT broker that we wrote in Rust. MQTT is extremely lightweight publish/subscribe messaging transport for the Internet of Things (IoT).

We will install Ambassador Gateway which is an open-source Kubernetes-native API gateway for microservices. We will use it as a reverse proxy to manage external access to services within our Kubernetes cluster.

Command and Query services APIs can be managed via lightweight, independently deployable, and scalable API gateways that can run anywhere that allow developers to manage API endpoints. They can handle extremely large volumes, as they run on highly scalable platforms, for example, Apache APISIX, Kong, Tyk, and Ambassador to name a few.

Ambassador

Did you know that it takes 23 minutes to get into a flow state? For some people it takes even longer. That means that for every question, disruption, email, and interruption that you or your coworkers are subjected to, it could be half an hour of productivity down the drain. We talked to Katie Wilde, VP of Engineering at Ambassador Labs, about how she manages workflow

Let's dive deep and start understanding more bit about Emissary Ingress.

Emissary is pretty much the gold standard for people with complicated setups: https://github.com/emissary-ingress/emissary

Katie Wilde, VP of Engineering at Ambassador Labs, knows your pain and she’s on a crusade to help devs everywhere reclaim their focus.

Ambassador API Gateway is an Envoy-based ingress controller.

I am starting to doubt their marketing materials about broad adoption, because we cannot get it to work even with basic setup. Apart from terrible DX (e.g. you can provide whatever arbitrary configs, there is no validation), we keep hitting bug after bug after bug. They are not small bugs either, e.g. broken redirects. Any time I try asking questions in their Slack, their sales rep will message asking to "connect via zoom meeting to cover the pricing".

Peter: Yeah. So that was my first time having a DevRel title. I was a developer Advocate for Ambassador Labs, another startup. And so I think they were Series B at the time. They were centered around the developer experience. So I had a lot of fun diving into the DevRel industry with them. And so my manager that I was working for has a long history of DevRel. And so I got to learn a lot of tips and tricks from him.
