In this post, I'll demonstrate how to build development environments for AWS Glue 1.0 and 2.0 using the Docker image and the Visual Studio Code Remote - Containers extension.

Authorization is the mechanism that controls who can do what on which resource in an application and it is a critical part of an application. In this post, I'll illustrate how to set up authorization in a GraphQL API using a custom directive and Oso, an open-source authorization library.

In this post, it is demonstrated how AWS Lambda can be integrated with Apache Airflow using a custom operator inspired by the ECS Operator.

Traefik is a modern HTTP reverse proxy and load balancer. In this post, it'll be demonstrated how path-based routing can be set up by Traefik with Docker. Also a centralized authentication will be illustrated with the Forward Authentication feature of Traefik.

In this post, I'll illustrate how a web service is created using FastAPI framework where tasks are sent to multiple workers. The workers are built with Celery and Rserve. Redis is used as a message broker/result backend for Celery and a key-value store for Rserve. Demos can be run in both Docker Compose and Kubernetes.

In this post, I'll demonstrate how to create a Linux development environment on Windows using WSL. Also an example app (Rserve web service with a sidecar container) on Minikube will be demonstrated.

LocalStack provides an easy-to-use test/mocking framework for developing AWS applications. In this post, I'll demonstrate how to utilize LocalStack for development using a web service.

Cronicle is a multi-server task scheduler and runner. In this post, multi-server configuration of Cronicle will be demonstrated with Docker and Nginx as load balancer.

Although R Shiny added async features but it has limitation when compared to Javascript. In this post, I'll demonstrate how to render htmlwigets in a Vue application in a more performant way as well as how to replace those widgets with native Javascript libraries.

In this post, it'll be demonstrated how to implement the async feature of Shiny. Then its limitation will be discussed with an alternative app, which is built by JavaScript for the frontend and RServe for the backend.
