1) VNET – Overview Azure Virtual Network (VNet) là một dịch vụ cơ bản trong Microsoft Azure, cho phép bạn tạo ra một mạng riêng ảo để kết nối và quản lý các tài nguyên như máy ảo (VM), ứng dụng, cơ sở dữ liệu, và các dịch vụ khác trong môi trường đám mây….
Creator: https://github.com/trungvo11 Crossplane is an open-source project in the Cloud Native Computing Foundation (CNCF) that transforms your Kubernetes cluster into a universal control plane. It enables platform teams to assemble infrastructure from multiple vendors and expose higher-level self-service APIs for application teams to consume, without writing any code. Crossplane extends your Kubernetes cluster to support…

NodeLocal DNSCache NodeLocal DNSCache enhances Kubernetes cluster DNS performance by deploying a DNS caching agent on each node as a DaemonSet. This setup allows Pods to query a local DNS cache on the same node, reducing latency and avoiding potential bottlenecks associated with centralized DNS services. PILLAR__DNS__DOMAIN is “cluster.local” by default.PILLAR__LOCAL__DNS is the local listen IP…

![[AWS] Using FSx Lustre to enhance disk performance for large-scale applications.](https://nimtechnology.com/wp-content/uploads/2024/12/image-8.png?v=1733626623)
1) Understand FSx Lustre to support EKS. Amazon FSx for Lustre is designed for high performance and its throughput and IOPS scale with the storage capacity you provision. This means there aren’t fixed maximums like with EFS. Instead, you get more throughput and IOPS as you increase your storage cũng như EFS, FSx Lustre cũng…

refer to: https://ramimac.me/aws-iam-tools-2024?ref=dailydev Identity and Access Management (IAM) is a cornerstone of security. However, AWS IAM is not only crucially important, but also immensely complex. This complexity and the resultant challenges it can pose for security have not gone unnoticed. In addition to efforts at education, AWS has developed Zelkova, an automated reasoning tool for AWS…
