This video provides a clear guide on configuring Nginx for multi-tenancy using wildcard subdomains, detailing the integration of SSL certificates via Certbot and Let’s Encrypt with necessary DNS authentication for wildcard certificates.
It demonstrates how to handle dynamic subdomains by capturing them as a variable in Nginx and passing this information to your application for effective multi-tenant serving.

It offers valuable perspectives and answers to these struggles, emphasizing the importance of continuous learning, maintaining your passion, and facing difficulties without fear because you are not alone.
If you’re seeking advice or a relatable experience to help find balance in your DevOps career, I believe this article is for you. The author writes with insightful perspectives and emotion, and you might find yourself reflected in their story.

It demonstrates building a streaming data architecture using Flink SQL with Apache Kafka and Apache Iceberg.
It covers integration via a Hive catalog and discusses a fully automated deployment approach.
It introduces related concepts and techniques for streaming implementation, such as Dead Letter Queue (DLQ) and Data Lake Copy on Write (CoW) and Merge on Write (MoW).
The article is described as exceptionally detailed and comprehensive, offering a wealth of information for deep exploration of modern streaming technologies.
Its level of detail and scope are noted as particularly impressive.

It explains why there are so many different types of databases.
It discusses how their unique characteristics are useful for data structuring and architecture, particularly for those interested in data or architecture roles.
The article covers approximately nine distinct database types.
For each type, it details the situations it suits, provides examples, and explains the circumstances for choosing it.

It provides a comparison of popular web frameworks from different programming languages, tested under high load (handling a billion requests).
The article aims to help you choose a suitable tech stack for your needs.
It includes details about the test cases and setup used.
It offers analysis and commentary on each framework’s performance.
It highlights the strengths and weaknesses of each framework.

This article introduces a new Kubernetes 1.33 feature that allows in-place pod resizing. Unlike the traditional Vertical Pod Autoscaler (VPA), which often requires restarting pods, this new approach avoids service interruption by signaling kubelet to adjust resources directly on a running pod.
It explains how this feature progressed to the Beta stage and provides a detailed walkthrough for implementation.
The author also discusses the feature’s pros and cons, including the trade-offs involved and other relevant considerations.

It offers a collection of OWASP-based strategies for securing your Kubernetes cluster.
The article introduces various concepts and techniques, providing opportunities for further research.
The author also recommends tools for enhancing security.
It serves as a good starting point for securing container and Kubernetes environments.
I try highlights that security involves trade-offs and stresses the importance of understanding your specific environment and operational needs over simply adopting technology trends. (Note: Some concepts are complex, and careful consideration is advised before implementation in a production environment.)

I was very impressed by this article, as it covers many categories of security for Kubernetes and container environments. It helps you gain knowledge to protect your services from both internal and external perspectives when deploying them.
It offers many suggestions, including CLI examples and tools, to help you find suitable options for your production environment. The content is quite interesting, and you likely won’t be disappointed by the information provided. (Important Note: The article implies that understanding the implications and subsequent stages is truly more important than just following instructions like reading a book.) 😄
