If it's anything like the original Autopilot was: yes. I had one of the first Model S vehicles that was autopilot-capable. Early enough that autopilot itself was added later. The early versions were... intense. Not just in the "if

If you're buying puts you have bounded risk (the amount you invested), albeit with a more cliff-like risk profile than other strategies.

Today I learned! I'll admit I didn't know this functionality existed, and I've instead had used instances.insert following by querying the VM resource. This is nicer!

by jsolson 4y ago
As far as I know, the `instances.insert` API only allows individual VMs, although the CLI can issue a bulk set of API calls[0], and MIGs (see below) allow you to request many identical VMs with a single API call if that's for some reas

Sure, except I think that at a macro level we got it more right than AWS, despite some choices that I believe we'd make differently today.

You're entitled to that takeaway, but I disagree. I believe GCP's tendency to use caller-supplied names for resources is one of the single best features of the platform, particularly when compared against AWS's random hex ide

I mean, it's kinda nice to know that if you reissue a request for an instance that could costs thousands of dollars per month due to a network glitch that you won't accidentally create two of them? More practically, though, the in

This is mostly not true in cases where resources are actually available (and in GCE if they're not the API rejects the VM outright, in general). To the extent that it is true for Borg when the job schedules immediately, it's large

Idempotency. You're inserting a VM with a specific name. If you try to create the same resource twice, the GCE control plane reports that as a conflict. What they're doing here would be roughly equivalent to supplying the time to

Depends on the trust? If your ideas are abstract and roughly "climate isn't fucked" they seem pretty perennial. They're also open to interpretation. That said, sure, lots of periods in history would've produced trus

When your job is to build infrastructure, "in a data-center" does not necessarily mean it's a production server :)

Ah, no, the fairly was merely that we omitted details and some things have changed. That said, the paper completely captures the use of Lanai in GCP's networking data plane.
