This article provides insights into Virtual Nodes feature (in preview) of Azure Kubernetes Service (AKS). Enabling virtual nodes for AKS cluster allows to deploy or burst out containers to nodes backed by serverless Azure Container Instances beyond the defined cluster size. Also, along with fast provisioning of Pods, you only pay per second for their execution time. AKS virtual nodes currently support Linux container instances only.
Add real-time web functionality to Angular application using ASP.NET Core SignalR, Azure SignalR service and Azure SignalR Service bindings for Azure Functions 2.0
This is the next part of the series on developing and deploying
- Angular, ASP.NET Core Web API and SQL Server to Azure Kubernetes Service
- Function Apps using Azure Functions 2.0 runtime
In this article I am going to go through steps needed to add real-time web functionality to Angular App using ASP.NET Core SignalR and Azure SignalR Service bindings for Azure Functions 2.0. The specific topics which this article is going to cover are
- Add ASP.NET Core SignalR to ASP.NET Core 2.1 Web API
- ASP.NET Core SignalR
- ASP.NET Core SignalR scale out using
- Azure SignalR Service backplane
- Redis Cache backplane
- Publish/Subscribe messages to SignalR Hub from Angular App
- Publish/Subscribe messages to SignalR Hub using Azure SignalR Service bindings for Azure Functions 2.0 from Angular App
- Build Docker images and deploy to Azure Kubernetes Service
