We’ve decided to knock our house down.

We do intend to rebuild it though. Back when we decided to take on this project, we had some important questions to answer.

One of the first was “how big should the new house be?”.

It’s not simple. Today, there’s me and Mrs Me plus our teenage daughter. We’ll also want some guest accommodation. And a home office.

So is that three bedrooms? Four? But then once our daughter leaves home, our need for space decreases and a fourth bedroom becomes wasted space.

Houses aren’t really that flexible. We need to decide now what our house size requirements for the next quite-a-few years.

Perhaps we should err on the side of caution and have four anyway.

IT systems used to be rigid like that. How much memory do you want? How much disk space? How fast should the processors be?

When you bought the hardware, you needed to have already decided what your server requirements would be for the next 3-5 years.

I once saw someone buy three servers with the maximum amount of memory the manufacturer could fit “just in case”.

That’s an expensive insurance policy.

Your business IT demands do change over time, and with the best will in the world, it’s hard – if not impossible – to predict how they will change.

Just this year, the IT requirements of many businesses have become much higher – or, in some cases, much lower – that they’d expected only six months ago.

The ability to flex to a change in demand in either direction is called scalability.

Scalability is one of the big advantages of migrating to the Cloud.

Start small. Meet success, scale up. Demand drops, scale back. And do so either automatically or manually, whatever you prefer.

Computing in the Cloud makes this easy. No capital expenditure. No having to forecast demand years in advance. Optimal size IT, all the time.

Much easier than deciding what size house you need.

Interested in better scalability? Let’s talk.
