What is the definition of an "application"? We are "applications development and delivery professionals" - surely we have this question nailed, don't we? The question keeps coming up in different contexts, and since there are many potential opinions, a blog is the perfect place to spur debate. Here are some (simplistic) questions to generate debate:
Is a Web page an application?
If not, how many Web pages does it take until I consider it an application - 10, 100, 1,000?
Does size matter? (Please behave yourselves with this one.)
Is the size of the code base a pertinent factor?
What about SharePoint sites, Access databases, and spreadsheets? Are they applications?
Where do COTS and packaged apps fit?
Does the technology I use affect the definition?
If I use a scripting language for a quick-and-dirty task, is that an application?
Does SOA erode the definition of an application?
Do we cease thinking about applications as entities and think about them more as containers that hold collections of SOA services?
How does open source affect the definition?
How does my role affect my perception of an application?
Do developers and users use similar definitions?
I have my opinions - in fact I just finished a draft piece of research on it that will be published in January, but what are your opinions?
In his report on the top technology trends to watch in 2011 to 2013, my colleague Gene Leganza called out application portfolio management (APM) as one of a number of "planning and analysis tools to manage the future." Forrester clients seem to agree with Gene; in fact they aren't even waiting until 2011 - their interest has been building steadily throughout the second half of 2010.
