Robert Annett, TweetAll successful systems become legacy eventually
Biography: Robert Annett
Robert Annett has been a developer since 1995 and worked in industries from energy management to investment banking. Much of this work has involved upgrading and migrating legacy systems with the occasional green-field project (with integration to legacy systems, of course). He has worked in the IT industry long enough to realize that ALL successful systems become legacy eventually.
Presentation: TweetModern Legacy Systems
The term "Legacy System" conjures up images of a vast mainframe (with whirring tapes and flashing diodes) running COBOL programs in a basement. However, many current computing stacks are quite old and have many legacy implementations. Although Java/JVM is still at the cutting edge of innovation it's a language and ecosystem that's been around since 1995 (18 years) and C#/.NET is not much younger at 13 years old.
There are many Java and .NET based systems that haven't been touched in over a decade and this presentation explores some of the issues of upgrading, maintaining or replacing them and provides some pointers on solving common problems.
