The recent AWS outage got me thinking about how we manage complexity in our IT systems. It’s a good reminder that in business, we should always try to cut down on the disorder, or ‘entropy’, that creeps in over time. When things get too varied, systems can break in ways we don’t expect. On the flip side, if everything is exactly the same, a single problem can bring the whole lot down at once.
Key Takeaways
- Balance is Best: Aim for a few variations in your systems, not too many and not too few.
- Complexity Grows: Unchecked, complexity naturally increases over time.
- Simplicity Pays Off: Keeping things simple makes them more reliable, easier to scale, and quicker to recover from issues.
The Problem with Too Much Variation
Think about it: if every single server, every piece of software, every setting is identical, then when one thing goes wrong, they all go wrong. It’s like having a whole row of dominoes set up – push one, and they all fall. This is a common issue in IT, but it pops up in other parts of business too. Complexity just builds up naturally if you don’t keep an eye on it.
Finding the Right Balance
So, what’s the answer? It’s about finding that sweet spot. You want a little bit of diversity to make sure that if one part of your system fails, others can keep going. This helps with resilience. But you don’t want so much variation that it becomes a tangled mess, hard to manage, and slow to fix when something breaks. The goal is to keep that complexity as low as possible while still having enough variety for things to keep running if a problem occurs.
Why Simplicity Matters
Keeping things simple really does make a difference. When your IT setup is straightforward, it’s naturally more reliable. It’s also easier to scale up when your business grows, and when things do go wrong – because they sometimes do – it’s much quicker and easier to get back up and running. A bit of controlled variation is good, but too much chaos can really slow everything down and make recovery a nightmare. It’s a simple thought, but a really important one for keeping your business running smoothly.
