- Data is replicated cross region, but your compute all lives in the same AZ, so if (when) an AZ goes down you have to wait for a new instance to be created elsewhere. AWS says the time for this is undefined, IIRC we've seen it be around 15-20 minutes before the DB is back online.
- If you have lots of long running transactions or queries, serverless can have trouble finding a scaling point and won't scale up/down. You can set it to force scaling after 5 attempts, but this results in dropped connections and 1-2 minutes of downtime every time.
- Scaling up actually takes 45s-1:30 for new capacity to be available. If your load is spiky enough that that's too slow, you're stuck with overprovisioning anyways.
- Tools like VividCortex don't work for serverless if you rely on those. Teams here that use serverless have shifted to DataDog APM for this purpose.
- Loading data from S3 doesn't work. This wasn't really a usecase we had but it's something to be aware of.
That said, for gradual load or DB downtime tolerant services it's great! Also very nice for dev environments as the scaling down to 0 can result in some very real cost savings.
Lots of business were crying foul at the start of the pilot, but credit card transaction data the city has hasn't borne that out.

As a seller I know that if a Visa payment clears I'll be getting that money, even if the customer doesn't have it. I don't need to arrange financing or risk taking a check that may bounce long after the customer has disappeared.
As a consumer, I get some measure of protection from fraud and have the option of doing a chargeback and letting Visa sort things out with the vendor if something is not as described.

Slack is a perfect example of this. They still have a small office down the street from me here in Vancouver, but they're based out of SF now. I can totally see why given the access to capital and talent in SF vs Van.
Edit: Where can I file bug reports? :)
> A single account was never seen to have two instances simultaneously running on the same physical machine, so running n instances in parallel under a single account results in placement on n separate machines
// At this point, I'd like to take a moment to speak to you about the Adobe PSD format.
// PSD is not a good format. PSD is not even a bad format. Calling it such would be an
// insult to other bad formats, such as PCX or JPEG. No, PSD is an abysmal format. Having
// worked on this code for several weeks now, my hate for PSD has grown to a raging fire
// that burns with the fierce passion of a million suns.
// If there are two different ways of doing something, PSD will do both, in different
// places. It will then make up three more ways no sane human would think of, and do those
// too. PSD makes inconsistency an art form. Why, for instance, did it suddenly decide
// that *these* particular chunks should be aligned to four bytes, and that this alignement
// should *not* be included in the size? Other chunks in other places are either unaligned,
// or aligned with the alignment included in the size. Here, though, it is not included.
// Either one of these three behaviours would be fine. A sane format would pick one. PSD,
// of course, uses all three, and more.
// Trying to get data out of a PSD file is like trying to find something in the attic of
// your eccentric old uncle who died in a freak freshwater shark attack on his 58th
// birthday. That last detail may not be important for the purposes of the simile, but
// at this point I am spending a lot of time imagining amusing fates for the people
// responsible for this Rube Goldberg of a file format.
// Earlier, I tried to get a hold of the latest specs for the PSD file format. To do this,
// I had to apply to them for permission to apply to them to have them consider sending
// me this sacred tome. This would have involved faxing them a copy of some document or
// other, probably signed in blood. I can only imagine that they make this process so
// difficult because they are intensely ashamed of having created this abomination. I
// was naturally not gullible enough to go through with this procedure, but if I had done
// so, I would have printed out every single page of the spec, and set them all on fire.
// Were it within my power, I would gather every single copy of those specs, and launch
// them on a spaceship directly into the sun.
//
// PSD is not my favourite file format.
1: https://github.com/zepouet/Xee-xCode-4.5/blob/master/XeePhot...MEC in Canada has the same problem. Sometime around when their logo changed from the mountains to a modern box with "MEC" written in it they stopped stocking as much high quality gear and much of their in house stuff saw a decline in durability/functionality in the name of fashion. Although speaking to people who work there they had solid market research showing that the old audience of hardcore outdoorspeople would no longer be enough to support them as it was shrinking fairly rapidly.
These days I mostly stick to Arc'teryx outers/shells, Patagonia for my mid layers, and icebreaker for baselayers. All of my gear from any of those companies has proven to be reliable and durable if pricey. I've heard good things about Peak Performance and Rab as well, but I've yet to purchase anything from them.
Edit: since this is now the recommend brands that are good but people maybe haven't heard of thread, I'd also like to plug Hestra, Fjallraven, and Osprey Packs
Running it locally on the user's machine would take far too long to train, especially as you would have to use the CPU in the majority of cases since many people don't have a separate GPU.
