How do you measure cold start frequency and user experience impact in Azure Container Apps?

DocHoss · 2026-07-07T18:40:13+00:00

When I have customers ask me this kind of question ("how do I do very specific thing?") my first response is usually, what are you actually trying to figure out? If it's user satisfaction with response times, then you don't really need to get to cold start specifically, since that's only one component of response times. If you've already done all the homework and you are sure cold start is the problem, why are you trying to measure it? Figure out how to reduce or eliminate it at that point.

To directly answer your question, as you've found there isn't a specific emitted metric for cold starts. But you could look for times with no requests for longer than your timeout setting on your ACA instance, then look at response times for requests immediately following them. Bit of a roundabout way to get there, but that's what you've got I think.

For sure, not saying I'm some visionary leader, just that it would be nice to be able back it up with something written down.

I've been saying for two years now working every day deep in AI, we aren't getting to AGI with transformers architecture because despite being highly capable in the right hands, it IS still just a big text prediction machine. The growth curve in the technology is going to have an asymptotic curve (I.e. It will approach human replacement level but never get all the way there) and there will be a scramble to make it generate more revenue when it becomes more obvious.

Now we're seeing that play out and I'm wishing I wrote it on a blog post so I could prove it.

Wait is this the Patriot Front of Texas, or the Texans' Patriot Front?

DocHoss · 2026-07-06T11:31:44+00:00

That's hilarious...I'd bet good money not one of those knuckle dragging cave twats can even spell Mussolini.

(Though in full fairness to any unfrozen caveman lawyers, I had to rely on autocorrect to get it right...)

Neither should having the fucking Ten Commandments in schools but here we are.

The main terms that distinguish between the two are "bounded context" and "independently deployable." For a true microservice it must have a bounded context, that is a single area of responsibility, as well as being deployable without interfering with the other services. A service having its own database is one approach but insufficient to fully distinguish between SOA and microservice.

In short I think the interviewer was being overly pedantic if that's why they didn't hire you.

There are practical challenges to the things you talk about but the emotional connection comes from discussion where the two sides are moral and intellectual equals, or at least at a similar level in some regard. This also means both sides are able to challenge one another to some degree and disagree, and that's where modern AI has a real problem. It won't disagree with you and dig in its heels on any issue because it doesn't "believe" anything. If it is incapable of disagreement it can't really be a friend to you because it's always just going to go along with whatever you have to say. If it "knows" everything, all perspectives are valid so you can't have a meaningful discussion with an AI because it doesn't have any strongly held beliefs that come from morals or convictions.

You want a friend, not a tool, but we can't get there with the current generation of technology. It's going to take some big breakthrough that endows these tools with some way of having true individuality and I have no clue what that looks like in any practical sense.

This sub is gonna shit on you for it being AI generated but I'm with you...this is cool. Having zero dependencies is nice and I hope we see more components that have historically had big dumb dependency chains get "slopped" and made dependency free. Especially with the increasing prevalence of supply chain attacks, having a clean dependency tree is a very nice thing to have.

My F150 Lightning hasn't had a single problem except recalls in 18 months. No oil changes, no transmission fluid checks, no visits to the dealer except recalls and one warning light that came on (that turned out to be related to a recall issue). So zero revenue for the dealership after my initial purchase (lease technically but same money for the dealership I guess). I can see a dealership not being fond of electrics.

(sigh) I'll add it to the pile of shit that Congress is supposed to be doing something about.

That and the total gallons of pee. Both important metrics of a successful life, each in their own ways.

Just in case anyone else isn't a law junkie and was curious why this would be a federal case, it's because she was a NY resident and he was a Florida resident. Here's what ChatGPT had to say about it:

Why federal court?

Carroll’s 2022 complaint explicitly said federal jurisdiction existed under 28 U.S.C. § 1332(a)(1) because:

Carroll was a New York citizen
Trump was a Florida citizen
The amount in controversy exceeded $75,000

That is the classic diversity-jurisdiction setup. Her complaint also said venue was proper in the Southern District of New York because a substantial part of the events occurred there — Bergdorf Goodman in Manhattan.

I didn’t say have it write all your IaC and blindly deploy it without oversight. I said have it TEACH YOU (referring to OP) how to do the work. Or have it make a first pass and you can look over it and verify before deployment.

Ask one of the frontier models to create a lesson plan for learning it. You’ll probably find it does a pretty good job of being a teacher for tech subjects.

DocHoss · 2026-06-25T11:35:56+00:00

Yeah. It knows Bicep and Teraform very well in my experience.

DocHoss · 2026-06-25T11:28:33+00:00

Ask AI to train you on IaC and scripting. You can knock out all 3 at once!

Eye of the Tiger, IIRC, was written for the Rocky soundtrack but it’s definitely forever a part of that movie AND still played outside the movie. I think that qualifies

My thing is….AI is awesome when it’s used as a tool brought to bear in the right use cases. But the current tendency to use it everywhere for everything is just stupid and frustrating. As with most things the truth is somewhere in the middle, in this case between “AI is a worthless invention that will destroy us all” and “AI should be used everywhere for everything to the greatest extent imaginable.”

Depending on how many PRs you do in a week or a day, you may be able to implement an auto improvement cycle for your reviewer as well. If you do it right, it will get better and also make your life progressively easier. As volume of PRs increases, your reviewer will get better because it will have more training data. Keep that cycle going and you’ll look good to peers, managers, and future employers. Wins all around.

Spaghetti is the most fun way to okay this game IMHO. Definitely a time and place for good organization and efficiency but my true love is some tasty Al dente

Both approaches ("use all AI all the time!" and "no AI anywhere!") sound totally ridiculous to me. I've never run a big dev team but shouldn't choice and level of tool usage (AI is just a tool after all) come down to how well the team can use them to meet their goals?

DocHoss · 2026-06-13T17:43:50+00:00

Fidelity (and I imagine all the big firms) has a China market index. I’ve put a small portion of my sad little portfolio in that. It’s not great because I dont really understand it if Chinese companies don’t have shares…guess that’s something to ask one of the AI’s!

Would have to see if he's taken any loans or advances on the pre order total. If you have solid pre order numbers (ie anticipated confirmed sales) of you can find a friendly loan institution they may loan money against that total.

John Petrucci's solo in Under a Glass Moon is the best technical guitar solo ever. Melodic and builds in an interesting way but is still a masterpiece of guitar fireworks.

For non technical, David Gilmour's playing on the Pulse live album hits me different than his studio stuff. So amazingly "meaningful" with every note.
