Setting yourself up to scale.
Which is more effective, to build the foundation before the house, or vice versa? When preparing for scalable growth, it is crucial to determine the most effective approach. Should we focus on establishing a solid foundation first or prioritize growth before building the necessary infrastructure? The answer lies in finding the right balance. While waiting for our first users, we must prioritize the most important things. You don’t need backup plans for backup plans, nor invest in office space for thousands of employees or purchase excessive cloud storage when you haven't even made your first sale. Instead, remain lean and agile, prepared to scale when the time is right, with just enough space and resources to keep moving forward.
The one thing that always worries me is a massive influx to whatever I'm building resulting in cloud bills I wouldn't be able to pay (or at least have a fright over), how does this play into scale? You need to be able to scale but at what cost?
A nice way to not have to deal with a runaway cloud bill is to use a fixed cost VPS to host the first iterations of your product. I use DigitalOcean (also see Linode) for this myself and it's always $6/mo – no guess work.
The downside is that if you have the very good problem of too much load and too much interest in your product, that VPS will not be able to handle all the load. But you'll find that out and adjust if that day does come.
Most VPS providers allow you to 'scale up' that single VPS as well so it's something you can go pretty far with.
