Red Node vs N8n

Image
  πŸ€– Node-RED vs n8n: What’s the Difference? Both Node-RED and n8n are visual workflow automation platforms , but they are designed for somewhat different uses and audiences. Most people compare them when choosing tools for automation, integrations, or connecting systems without heavy coding. πŸ› ️ Overview πŸ”§ Node-RED Developed originally by IBM as a flow-based low-code tool. Excellent for IoT (Internet of Things) , device control, real-time event automation, and edge computing projects. Runs on Node.js and is completely open-source under Apache 2.0 — free forever. Often used with sensors, MQTT, and hardware integrations on things like Raspberry Pi. πŸ”„ n8n A more modern workflow automation platform focused on business systems, cloud apps, and APIs . Visual node-based editor designed for connecting SaaS tools, APIs, databases, and AI. Supports both self-hosting and managed cloud options. Uses a “fair-code” license with some feature restrictions in enterprise tiers. πŸ”Ž Key Com...

AI Chatbot Security: Protecting Conversations in the Age of Artificial Intelligence

  πŸ€– AI Chatbot Security: Protecting Conversations in the Age of Artificial Intelligence 4 Introduction AI chatbots are rapidly transforming how businesses interact with users—powering customer support, education, healthcare, and e-commerce. As these systems become more intelligent and more deeply integrated into daily life, AI chatbot security has become a critical concern. Chatbots often process sensitive information such as personal data, passwords, financial details, and confidential business information. Without strong security measures, they can become attractive targets for cyberattacks. This blog explores the key security risks , best practices , and future trends in securing AI chatbots. πŸ” Why AI Chatbot Security Matters AI chatbots interact directly with users, making them a unique cybersecurity challenge. A single vulnerability can expose thousands—or even millions—of conversations. Key reasons security is essential: Protection of user privacy Compliance with data pro...

Managing multiple clusters with ArgoCD in Azure/k3s secured w/ Traefik&Let’s Encrypt

Image
  Easily deploy ArgoCD in Azure to manage multiple clusters in a GitOps way. Code available at https://github.com/ams0/argocd-azure-k3s-traefik I heard about ArgoCD many times (recently from my friends at Fullstaq here) but never came around to kick its tires until now. If you don’t know, ArgoCD is a platform for declarative continuous deployment of Kubernetes applications, and it’s becoming quickly an exceedingly popular (and now it’s an incubated CNCF project) choice to deploy and manage applications at scale on  multiple  clusters. Since I want to use it for deploying to a cluster, my plan is to have an ArgoCD instance outside my clusters that can manage them independently from the clusters’ lifecycle; hence, I devise this method of deploying ArgoCD into a VM in azure running the lightweight distribution of Kubernetes from Rancher Labs, k3s (deployed using the k3d helper tool) and exposed via the Traefik ingress controller and secured with Let’s Encrypt certificates. L...

Bring your own Kubernetes cluster to Azure — Azure Arc

Image
  There are use cases where customers wants to bring on-premises resources to cloud and tap on cloud services to easily manage it as well. Microsoft Azure Arc helps you extend Azure management to any infrastructure and enables deployment of Azure data services anywhere. It actually simplify day to day monitoring and management of the resource from an operations perspective and you can leverage the goodness of cloud to on premise resources. Azure Arc is still in preview and currently supports Kubernetes, SQL Servers, VMs and HCI and additional features are being developed under the hood. Initially I thought to onboard my Raspberry Pi cluster to Arc, but unfortunately preview version doesn’t support armv7 or armv8 architecture yet. So in this article , we will setup a Kubernetes single node on a VM and integrate with Azure Arc. We can easily setup a Kubernetes cluster using Rancher K3s. Please not that you need to have Azure Account and subscription to setup the following resources. ...

Kubernetes Locally using - minikube, microk8s, k3s, k3d, k0s, kind, crc, minishift, firekube

  Kubernetes   is a container orchestration tool that is open source. It is an open source system developed by Google for automating the deployment, scaling, and management of containerized applications. Although most people use Kubernetes in the cloud, it is feasible to host a Kubernetes cluster locally, and reap some of the benefits of hosting it locally. You may easily test Kubernetes before determining whether or not to adopt it as your  principal platform for application deployment.  You can use it as a local development environment before pushing anything to the cloud, allowing you to keep the development and production environments separate. Setting up a local Kubernetes environment as your development environment is the best solution, regardless of your...
