Ingress
The process of incoming traffic or data entering a network or service.
Description
In the context of AWS (Amazon Web Services), 'Ingress' refers to the incoming network traffic that is directed towards a resource within the AWS cloud. This can include traffic from users accessing web applications hosted on Amazon EC2 instances, data being sent to Amazon S3 for storage, or API calls made to AWS services. AWS provides various tools and services to manage and control ingress traffic, such as Security Groups and Network Access Control Lists (ACLs), which help define rules that govern which traffic is allowed or denied. Proper management of ingress is crucial for ensuring security, optimizing performance, and managing costs associated with data transfer. For instance, misconfigured ingress settings can lead to vulnerabilities, allowing unauthorized access to resources, while correctly configured settings can enhance application availability and user experience. Understanding ingress traffic patterns can also aid in scaling resources effectively during peak usage times.
Examples
- A web application hosted on Amazon EC2 receiving HTTP requests from users across the globe.
- Data uploads to Amazon S3 buckets from various sources, such as IoT devices sending telemetry data.
Additional Information
- Ingress can be monitored and analyzed using AWS CloudWatch to gain insights into traffic patterns and performance.
- AWS services like AWS WAF (Web Application Firewall) can be used to protect against malicious ingress traffic.
