Web Proxy

A program that intercepts internal user browsing traffic in order to content-filter traffic, detect/block malware, track usage, and provide caching; it authenticates users for tracking usage and unique filtering rules.

GSLB

Global Load Balancer; A DNS-based solution that provides failover to another geographic site, offering health checking and automated failover but not session stickiness or TLS offloading.

Tunneling

A technique that allows transmissions between two devices that otherwise could not communicate, by encapsulating their conversation within another protocol.

Job Scheduling

Also called batch job scheduling or event-based scheduling; the execution of unattended processes based on conditions such as date/time, job dependencies, file creation, or any combination of these.

Local Load Balancing

The distribution of incoming network traffic across multiple backend servers using a reverse proxy, with services such as health checking, session stickiness, and TLS offloading.

Network Segmentation

The common corporate practice of dividing a network into smaller, typically secured subnets to improve security, control visitor access, reduce congestion, and contain network problems.

Message Queuing

A technique that supports asynchronous communications by allowing producers to place messages in queues and consumers to extract them, guaranteeing message delivery.

Proxying

A program that establishes itself between two communicating hosts, terminating the network connection on one side and establishing a new one on the other, allowing it to stop or alter the communication stream.

Reverse Proxy

To provide an Internet web presence in a DMZ (Demilitarized Zone), protecting backend application servers from direct exposure to the Internet; it typically forwards the original source IP in an HTTP header for tracking purposes.

Amazon S3

Amazon Simple Storage Service

Web Server
