I have entitled this post "The Cloud", but it is really not just about the cloud. It is more about how we seem to spend so much of our time inventing new ways to design, create and field substandard applications. People who actually have to write real applications for real businesses, or more often maintain applications that other people wrote, or interoperate with applications that other people wrote, realize that in 2012 we are actually no further ahead in writing quality software that does what the customer wants than we were decades ago, before the Internet even existed.
What is the point in enthusing about flavours of cloud, like IaaS or PaaS or SaaS, or pushing REST over SOAP, or using the latest and greatest SOA technology to redo attempts at EAI or B2B solutions, or jumping on the latest language or framework, when the core business logic - the code that actually really does something useful - is still inferior in quality?
It is not sexy or exciting to work on actual business logic. Create a project to work on NoSQL, or Big Data business analytics, and you have all sorts of people who want to work on the thing. If you throw in the latest languages and frameworks you will have no problems getting people to work on the application either...the technical trappings that is. But work on the actual business logic? Requirements, design, test plans, coding up the boilerplate, doing the hard work on the domain objects, designing the RDBMS schema? God forbid.
The IT industry needs people who spend years - many years - amassing expertise with dry-as-dust applications. The kinds of technologies that are niche and only meaningful to a handful of people. The industry needs software developers who spend so many years in an application domain that they know more about it than the majority of business practitioners. The industry needs software architects, analysts, designers, coders and testers who can go through exhausting but necessary rituals over and over again, for each new business problem, and deliver quality applications.
The key here is applications. The latest Big Buzz always seems to be about what languages will we write the applications in, what framework will we use, how will we deploy it, how will applications talk to each other...but much less of the conversation is about the actual applications. Sure, there is also always a buzz around the latest methodologies - iterative, agile, lean, unit testing, etc etc - but it is hard not to get the feeling that the application successes are because of high-quality teams that could have done a good job using waterfall if they had to, and not because of the methodologies.
Do not get me wrong. I love the new languages that appear every year. I love the attempts in existing languages to improve and stay relevant. Most of the new development methodologies have a lot to offer. There is much good stuff in SOA and the cloud technologies and NoSQL. The social space is important, and mobile is important. I could easily add to this list.
But what is still not receiving its due share of necessary attention is the hard work of writing solid business logic. And testing it. And designing the security for it. And maintaining it. And gathering the requirements for it. And writing good documentation for it. And spending hours upon hours of one's own time on professional development in learning, yes, dry-as-dust non-sexy non-buzzword technologies.
The fact is that all the hyped technologies are relevant to well under ten percent of all software developers. Ten percent is probably a very optimistic estimate; I would be surprised if more than 1 in 50 software developers is heavily involved in NoSQL or real cloud work or Big Data or the latest sexiest analytics work or in advanced mobile. The huge majority of us do the grunt work, and most of that is not done very well.
But I think we all know where we are headed. We used to have mediocre desktop software. We moved from there to mediocre web applications. Mobile has now provided us with thousands of mediocre portable apps we can put on our smartphones and tablets. And the cloud offers us the opportunity to host mediocre applications somewhere else other than on our own servers.
Spend some time down the road thinking about software engineering. Real honest-to-God Fred Brooks, Don Knuth, Steve McConnell, Trygve Reenskaug software engineering. Ask yourself when was the last time you participated in writing real applications that were solid and actually made a client happy. And ask yourself how you can make that happen more often.
