IaaS, PaaS, and SaaS — the three service layers explained by someone who managed physical servers before AWS existed. Honest tradeoffs, not vendor talking points.
How AI infrastructure demand is driving up VPS and dedicated server costs — and why your hosting bill is going up even though you haven't changed anything.
Infrastructure as a Service gives you virtualized servers, storage, and networking on demand without owning any hardware. You rent compute and own everything that runs on it. Here is what IaaS actually is, what it demands from you.
Platform as a Service sits between raw servers and fully managed software. You push code, the platform runs it. No Nginx config, no OS patches, no 3 AM server alerts. Here is what PaaS actually gives you, what it costs you in control, and how to decide if it is the right layer for your application.
oftware as a Service means the software runs on someone else's servers and you pay for access to it. No installation, no maintenance, no infrastructure. Here is what SaaS actually is, how it changed software delivery, and the decisions behind when it makes sense vs owning your own stack.
Go is Google's compiled language built for simplicity and brutal concurrency. Here's what it is, how it works, and why it runs half the cloud infrastructure you use every day.
