AMQP vs. MQTT: Technical Comparison for Enterprise Messaging and IIoT
AMQP and MQTT solve different problems: MQTT delivers lightweight publish/subscribe for IIoT and edge telemetry, while AMQP adds transactional integrity and durable queuing for enterprise backends. This comparison covers messaging models, routing, overhead, reliability, and scalability, and shows how a hybrid MQTT-AMQP architecture combines both.
ProtocolsMQTT vs. CoAP: Which Protocol Fits Your IoT Architecture?
MQTT and CoAP both target constrained IoT environments but make different architectural choices: MQTT uses TCP and a broker-based pub/sub model, CoAP uses UDP and REST-style request/response. This guide breaks down transport, messaging, overhead, security, and scalability, and gives a decision framework for choosing (or combining) the two.
ProtocolsAMQP Guide: Architecture and Implementation of the Enterprise Messaging Standard
AMQP is a standardized, binary messaging protocol for reliable, transactional data exchange across distributed enterprise systems. This guide explains the broker model (exchanges, queues, bindings), the four exchange types, message lifecycle, reliability and flow control, the difference between AMQP 0-9-1 and 1.0, and how AMQP fits alongside MQTT in industrial architectures.
ProtocolsWhat Is CoAP? The Lightweight IoT Protocol for Constrained Devices
CoAP compresses the HTTP request/response model into a 4-byte header that runs over UDP, targeting microcontrollers and constrained networks. This guide covers how CoAP works, its message types and Observe extension, where it fits in IoT architectures, CoAP vs. MQTT vs. HTTP, limitations at scale, and a step-by-step CoAP-to-MQTT integration path.
ProtocolsDataOps: A Practical Framework for Governed Industrial Data Workflows
DataOps applies the automation, testing, and collaboration principles of DevOps to data pipelines. This guide covers the methodology, a five-stage workflow, the platform capabilities that matter, what the EU Data Act and Data Governance Act mean for your pipelines, and how DataOps applies to OT/IT integration.
Industry 4.0Internet of Things (IoT) Protocols: How to Choose the Right Protocol for Secure IoT Architectures
IoT protocols define how devices, gateways, brokers, and cloud systems exchange data. This guide compares MQTT, CoAP, AMQP, HTTP, OPC UA, DDS, LoRaWAN, NB-IoT, and Bluetooth Low Energy, shows how to choose by use case, and covers the security and compliance requirements (CRA, NIS2, MDR) that shape protocol decisions in 2026.
ProtocolsSBOM: What a Software Bill of Materials Contains and How to Use It
An SBOM is a structured inventory of the software components and dependencies in your build. This guide explains what it contains, how CycloneDX and SPDX compare, how to generate one with Syft, validate it, turn it into a vulnerability report with VEX, and wire it into CI/CD, including the MQTT and edge layer.
MQTT securityWhat Is MQTTS? Secure MQTT over TLS for Industrial IoT in 2026
MQTTS is an MQTT connection wrapped in TLS, typically on port 8883 with the mqtts:// URI prefix. This guide explains how MQTTS works, when to use ports 8883, 443 or 1883, server-only versus mutual TLS, how to configure it in Mosquitto and paho, and why it has become the practical security baseline under NIS2, the EU Data Act and the Cyber Resilience Act.
MQTT securitySmart Factory: Definition, Technology and Compliance Requirements
A smart factory links machines, sensors, and IT systems through one shared data layer, turning production data into automated decisions in real time. This guide explains what a smart factory is, the technologies behind it (MQTT, Unified Namespace, edge and AI), the EU compliance rules to design around (NIS2, AI Act, Data Act), and how to scale from a test run to full operations.
Industry 4.0MQTT Security: A Practical Guide to TLS, Access Control, and Secure Operations
MQTT security problems rarely originate from the protocol itself. They arise when brokers run with weak identity, missing authorization, and little visibility into who publishes and subscribes to which data. This guide covers the four pillars of MQTT security - transport, identity, authorization, and governance - and how to operate them in production.
MQTT securityReal-Time Data Streaming: How Modern Systems Move Data With Near-Zero Delay
Real-time data streaming delivers continuous information with minimal delay. This guide explains how low-latency pipelines work, how streaming compares to batch processing, which technologies and reference architectures power modern setups, and the best practices teams use to keep IIoT and edge-to-cloud flows stable.
