Cloud Basics
Cloud Basics · clouddevops session.
Pipelines, containers and monitoring explained in proportion — including when the boring architecture is the right one.
Open The ToolsCloud and DevOps without the cargo cult: what each piece is for, what it costs, and how to run it without burning out the team.

What a task will really take, corrected by how your estimates have gone before.
Your estimate, corrected by how your estimates have gone before. It runs in your browser — nothing you type is sent anywhere.
People under-estimate their own work and over-estimate other people's — it holds even when they know about it. Breaking the task into pieces under four hours is the one thing that reliably shrinks the gap.
Free tools
Test a password, inspect a suspicious link, and see whether your details have already leaked — all in your browser, nothing sent anywhere.
SHA-256, SHA-384 and SHA-512 of any text, computed locally. Runs entirely in your browser; nothing you type leaves this page.
SHA-1 is here because old systems still use it. Do not choose it for anything new — it has been broken for years.
Free tools
Subnets, transfer times, uptime budgets and what your browser gives away — the sums nobody wants to do by hand.
CIDR in, network, broadcast, mask and usable host range out. Runs entirely in your browser; nothing you type leaves this page.
Type any address inside the network — it does not have to be the network address itself.
Free tools
Base64, URL encoding, JWT, JSON, UUIDs and timestamps. Runs locally, so you can paste real data into it.
Encode and decode, Unicode-safe, with a URL-safe option. Runs entirely in your browser; nothing you type leaves this page.
Unicode-safe both ways — text is converted through UTF-8 first, which is where most online encoders break.
Free tools
Power supply sizing, RAID capacity and a backup plan that actually survives a drive failure.
Usable space and fault tolerance for RAID 0, 1, 5, 6 and 10. Runs entirely in your browser; nothing you type leaves this page.
Drive makers count a terabyte as 1,000,000,000,000 bytes; your operating system does not. Expect roughly 9% less than these numbers once it is formatted.
Usable capacity
12TB
One drive of parity. With large modern drives a rebuild takes long enough that a second failure is a real risk.
