How to Test Microservices Application

                                          Photo by RF._.studio Debugging and testing microservices applications can be challenging due to their distributed nature. Here are some strategies to help you debug and test microservices effectively: Debugging Microservices: 1. Centralized Logging: - Implement centralized logging using tools like ELK (Elasticsearch, Logstash, Kibana) or centralized logging services. This allows you to trace logs across multiple services. 2. Distributed Tracing: - Use distributed tracing tools like Jaeger or Zipkin. They help track requests as they travel through various microservices, providing insights into latency and errors. 3. Service Mesh: - Consider using a service mesh like Istio or Linkerd. Service meshes provide observability features, such as traffic monitoring, security, and telemetry. 4. Container Orchestration ...

OTA Architecture

                                               Photo by Pixabay Developing an end-to-end Over-the-Air (OTA) update architecture for IoT devices in equipment like escalators and elevators involves several components. This architecture ensures that firmware updates can be delivered seamlessly and securely to the devices in the field. Here's an outline of the architecture with explanations and examples: 1. Device Firmware: - The IoT devices (escalators, elevators) have embedded firmware that needs to be updated over the air. - Example: The firmware manages the operation of the device, and we want to update it to fix bugs or add new features. 2. Update Server: - A central server responsible for managing firmware updates and distributing them to the devices. - Example: A cloud-based server that hosts the latest firmware versions. 3. Updat...

Bird View Image from Images Stiching by ML

                                                    Photo by Marcin Jozwiak Creating a top-level bird view diagram of a place with object detection involves several steps. Here's a high-level overview: 1. Camera Calibration : - Calibrate each camera to correct for distortion and obtain intrinsic and extrinsic parameters. NVIDIA DeepStream SDK primarily focuses on building AI-powered video analytics applications, including object detection and tracking, but it doesn't directly provide camera calibration functionalities out of the box. Camera calibration is typically a separate process that involves capturing images of a known calibration pattern (like a checkerboard) and using those images to determine the camera's intrinsic and extrinsic parameters. Here's a brief overview of how you might approach camera calibration using OpenCV...
