Complete Guide to Traffic Distribution, High Availability, and Load Balancing Strategies
Introduction to Load Balancing
Frequently Asked Questions
What is load balancing?
Load balancing distributes incoming network traffic across multiple servers to ensure optimal resource utilization,
What is session persistence (sticky sessions)?
Session persistence ensures requests from the same client go to the same server, maintaining session state. Implement
using IP hash, cookie-based routing, or session affinity. Use when applications maintain server-side session state.
Frequently asked questions
How can servers be protected from failure using health checks?
Health checks automatically monitor the status of servers and remove any that are failing from the load balancing rotation. This ensures continued service availability by directing traffic only to healthy instances.
What is automatic failover for servers, and how does it work?
Automatic failover involves configuring servers to seamlessly switch to a backup server in case of primary server failure. Continuous monitoring and active-passive or active-active configurations are key components.
How should failover procedures be tested for configuration changes?
Regular testing of failover procedures is crucial to validate their effectiveness and ensure reliability. This involves simulating server failures and verifying that traffic is correctly routed to backup servers.
What is geographic load balancing, and why is it important?
Geographic load balancing distributes network traffic based on the user's location, reducing latency and improving application performance for users around the world. It’s particularly valuable when serving a global audience.
