In Kubernetes (and computing in general), 1 vCPU means 1 virtual Central Processing Unit . What is 1 vCPU? vCPU stands for Virtual CPU. In a virtualized environment like AWS EC2 or Kubernetes, a vCPU represents a portion of the physical CPU resources allocated to a virtual machine or container. 1 vCPU = 1 Physical CPU Core or 1 Hyperthread (in many cases, especially with Intel and AMD processors using Hyper-Threading). In Kubernetes: Kubernetes abstracts compute resources using vCPUs. 1 vCPU in Kubernetes is equivalent to 1 CPU core on the underlying node . You can request or limit vCPU usage using resources.requests.cpu and resources.limits.cpu . Example resources: requests: cpu: "1" # Request 1 vCPU memory: "2Gi" limits: cpu: "2" # Limit to 2 vCPUs memory: "4Gi" Key Takeaways 1 vCPU is equivalent to 1 CPU core or 1 hyperthread depending on the hardware. Kubernetes uses millicores for fractional CPU requests (e.g., 500m = 0.5 vCPU ). Node...

MySQL default authentication plugin- mysql_native_password, caching_sha2_password AWS RDS for MySQL version 8.0.34 and higher 8.0 versions use the  mysql_native_password plugin. You can't change the default_authentication_plugin  setting. RDS for MySQL version 8.4 and higher versions use the  caching_sha2_password  plugin as the default authentication plugin.You can change the default authentication plugin for MySQL 8.4. The  mysql_native_password plugin still works with MySQL 8.4, but support of this plugin ends with MySQL 8.4 To change the default authentication plugin, create a custom parameter group and modify the value of the authentication_policy  parameter MySQL’s mysql_native_password plugin is deprecated starting from MySQL 8.0.34 , disabled by default in MySQL 8.4 , and removed entirely in MySQL 9.0 . Amazon RDS for MySQL has switched to caching_sha2_password as the default authentication plugin for improved security and performance Examp...

 EKS (Elastic Kubernetes Service) EKS is a managed service by AWS that runs Kubernetes for you. It takes care of setting up and managing the Kubernetes control plane so you can focus on running your applications. Kubernetes  Kubernetes is an open-source system for automating the deployment, scaling, and management of containerized applications. It helps run apps reliably across a cluster of machines, automatically handling scheduling, scaling, updates, and recovery. Pod A Pod is the smallest unit in Kubernetes. It can hold one or more containers that share the same network and storage. All containers in a pod are scheduled and managed together. Container A Container is a lightweight, standalone package that includes everything an app needs to run — code, runtime, libraries, and dependencies. It ensures the app runs the same no matter where it’s deployed. 👀1 pod can have multiple containers but 1 container cannot belongs to multiple pods.
