Modern Enterprise Application Systems Architecture
Introduction
The world has changed. Technology has changed.
Twenty-five years ago, we did not have the internet. Now, we could not live without it.
Enterprise systems used to be large, clunky, very expensive, slow, fragile, difficult to maintain, upgrade and replace. They used to be normally hosted in very large computers AKA Mainframes or very large and expensive Servers in a large and expensive server room or Data Centres.
Nevertheless, they were the only viable alternative for enterprises to improve productivity.
Sophisticated vendor management, especially on a global configuration, was paramount.
Nowadays, we are fortunate to have the option to deploy fantastic, best in class SaaS, subscription-based systems from multiple vendors, managed and supported by professionals and experts in their field.
