Development; Just as Important as Dual Nics
There is a popular saying which I find you can apply to most things in life; “You get what you pay for”. Sadly, this does not seem to apply for software development in any way. You who know me know that I work for a reasonably sized hosting company in the upper market segment. We have thousands of servers and hundreds of customers, so after a while you get a quite decent overview of how things work and a vast arsenal of “stories from the trenches”.
So here’s a small tip; ensure that your developers know what they are doing! It will save you a lot of hassle and money in the long run.
Without having made a science out of it, I can confidently say that at the very least 95% of the downtime I see on a daily basis is due to faulty code in the applications running on our servers.
So after you’ve demanded dual power feeds to your rack, bonded NICs and a gazillion physical paths to your dual controller SAN, it would make sense to apply the same attitude towards your developers. After all, they are carbon based humans and are far more likely to break than your silicon NIC. Now unfortunately it is not as simple as “if I pay someone a lot of money and let them do their thing, I will get good solid code out of it”, so a great deal of due diligence is required in this part of your environment as well. I have seen more plain stupid things coming from 50k pa. people than I care to mention, and I have seen plain brilliant things coming out of college kids’ basements.
This is important not only from an availability point of view, it’s also about running cost. The amount of hardware in our data centers which is completely redundant, and would easily be made obsolete with a bit of code and database tweaking is frightening. So you think you may have cut a great deal when someone said they could build your e-commerce system in 3 months for 10k less than other people have quoted you. But in actual fact, all you have done is got someone to effectively re-brand a bloated, way too generic, stock framework/product which the developer has very little insight into and control over. Yes, it works if you “click here, there and then that button”, the right thing does appear on the screen. But only after executing hundreds of SQL queries, looking for your session in three different places, done four HTTP redirects, read five config files and included 45 other source files. Needless to say, those one-off 10k you think you have saved, will be swallowed in recurring hardware cost in no time. You have probably also severely limited your ability to scale things up in the future.
So in summary, don’t cheap out on your development but at the same time don’t think that throwing money at people will make them write good code. Ask someone else to look things over every now and then, even if it will cost you a little bit. Use the budget you were planning on spending on the SEO consultant. Let it take time.
