Large technology solutions provider; its site publishes free technical research, labs and articles alongside its own job listings.
Why I recommend it: Two uses: a big employer worth knowing about, and a source of free hands-on technical labs if you are building infrastructure skills.
A Google Labs experiment that builds a short, finite set of personalised daily stories from the Google apps you choose to connect — an easy way to see what "personal" AI actually feels like. Free with a Google account in the U.S.
Hands-on cybersecurity training through guided browser-based labs.
Why I recommend it: A generous free tier and a public profile that shows what you actually completed. That profile is proof, which is more than a certificate.
