Kubernetes Ingress is an API object that provides HTTP and HTTPS routing to services based on rules. It acts as an entry point for external traffic into the cluster, managing external access to services. Ingress allows you to define how external HTTP/S traffic should be processed and routed to different services within the cluster. If you want to start with the beginning then you can click here Key components and concepts of Kubernetes Ingress include: 1. Ingress Resource:    - An Ingress resource is created to define the rules for how external HTTP/S traffic should be handled. 2. Rules:    - Rules define how requests should be routed based on the host and path specified in the incoming request. 3. Backend Services:    - Ingress directs traffic to backend services based on the defined rules. 4. TLS Termination:    - Ingress can handle TLS termination, allowing you to configure HTTPS for your services. 5. Annotations:    - Annotations pr...

The choice of protocols depends on various factors such as the nature of devices, network constraints, and the specific requirements of the IoT application. Here's a contextual overview of how protocols fit into the IoT landscape: 1. Diverse Ecosystem: - IoT encompasses a diverse ecosystem of devices ranging from sensors and actuators to smart appliances and industrial machines. - Different devices may have distinct communication needs, influencing the selection of protocols. 2. Resource Constraints: - Many IoT devices operate under resource constraints, including limited processing power, memory, and energy. ...

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 ...

                                               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...
