Overview
"The cloud" sounds ethereal, but it's a marketing word for something very physical: someone else's computers, in someone else's buildings, run by a handful of companies. Stripping away the abstraction clarifies the real trade-offs. This report does that.
The cloud is physical
When you "store something in the cloud," it lands on real hard drives and SSDs in real servers, in massive data centers with industrial power and cooling, owned by providers like the major hyperscalers. There's no magical "cloud" — just machines you rent instead of own. The abstraction is useful, but forgetting the physical reality leads to bad assumptions about cost, control, and risk.
What you're actually buying
You're renting capability and convenience: instant capacity, managed services, global reach, and someone else handling hardware, power, and maintenance. In exchange you give up control and pay an ongoing premium. For most teams that's a great deal — you focus on your product, not on running data centers. But it is a rental, with a landlord's terms.
Concentration is a hidden risk
A few providers run a huge share of the internet's infrastructure. That concentration means a single provider's outage can take down large swaths of unrelated services at once — something we see whenever a major region has problems. Your uptime is partly hostage to a vendor you don't control. Multi-region and multi-cloud strategies exist precisely to reduce this dependency.
Lock-in is a long-term cost
The cloud's convenient managed services are often proprietary. Build deeply on them and migrating away becomes expensive and hard — compounded by egress fees that charge you to move your own data out. This "vendor lock-in" is a real strategic cost that's easy to ignore early and painful to discover late.
What this means for you
Use the cloud for what it's great at — speed, elasticity, focus — with eyes open. Know where your data physically lives and under whose terms. Avoid unnecessary lock-in where you can, plan for provider outages, and periodically ask whether each workload still belongs there. "It's just the cloud" should never mean "I don't need to think about it."
Honest limits
For the vast majority of teams, renting compute beats running your own data center — the cloud's benefits are real and large. The point isn't anti-cloud; it's anti-magic. Treat it as rented physical infrastructure and make deliberate decisions.
