Node
A Node in AWS refers to a unit of computing resource within services like AWS Lambda, Amazon EC2, or Amazon EKS.
Description
In the context of AWS, a Node can represent a variety of concepts depending on the specific service being used. For instance, in Amazon EC2, a Node typically refers to a virtual server instance that can run applications and services. These nodes are part of a larger network, often working together to handle workloads and provide scalability. In AWS Lambda, a Node might refer to an execution environment for running serverless applications, where each invocation of a function can be considered a separate node that processes requests independently. In container orchestration services like Amazon EKS, a Node refers to a worker machine within a Kubernetes cluster that runs containerized applications. Each Node in a Kubernetes setup is managed by the control plane and can be scaled up or down based on demand, facilitating efficient resource management and application performance.
Examples
- An EC2 instance running a web application is considered a Node.
- A worker Node in an Amazon EKS cluster that executes containerized applications.
Additional Information
- Nodes can be dynamically added or removed based on workload requirements, enabling elasticity.
- Monitoring and management of Nodes can be done using AWS services like CloudWatch and the AWS Management Console.
