GSLB: Traffic Steering Made Simple

Summary: The video discusses Global Server Load Balancing (GSLB), which enhances application performance and availability by distributing user requests across multiple servers located in various regions. It explains different methods of traffic steering, including weighted round robin and geolocation-based techniques.

Keypoints:

Global Server Load Balancing (GSLB) improves application performance and availability.

User requests are spread across multiple servers in different locations.

Weighted round robin directs users to servers based on predefined weights.

Example: LA server has a weight of 50%, Tokyo server has a weight of 10%.

Geolocation-based traffic steering can be achieved through geofencing and geodistance.

Geofencing manually divides the world into regions for server assignment based on user location.

Geodistance calculates the shortest distance between users and server locations for optimal routing.
