In the last Back to Basics series, I looked at what “ADCs” and “Traffic Managers” actually do, and how they differ from ordinary “Load Balancers.” In this new series of articles, I am going to look at the topic of Global Load Balancing, how it works, and how you can use SteelApp to enhance application delivery for all applications, wherever they are based.
Online services are so pervasive now, with news and social media web sites, digital download, e-commerce stores – all run from global data centers and public cloud services across the world. However, if a datacenter fails, the service will not be available, and if the datacenter is too far away from the end user - in another continent for example - the service will appear to run very slowly.
Global Load Balancing is a technique used to deal with these two problems, helping to improve the performance and availability of global applications.
This series of articles describes how Global Load Balancing works, from a simple, non-technical perspective, and starts by comparing with a simple example of the Global Telephone Directory, starting here: The Layman’s Guide to Global Load Balancing.
