[674.98 --> 675.30] Yeah. |
[675.68 --> 676.86] Well, just $1,001. |
[677.50 --> 678.66] Would be worse, wouldn't it? |
[678.90 --> 679.20] It would. |
[679.58 --> 681.58] What would you do, Johnny, if you saw that? |
[682.00 --> 683.14] I'd call you and say, hey. |
[683.14 --> 685.20] You got a grand. |
[685.48 --> 685.96] I hear you. |
[686.08 --> 686.66] You're loaded. |
[687.28 --> 691.00] You're just wasting $1,000 here, $1,000 there on your bugs and stuff. |
[691.30 --> 694.34] Honestly, when I found out about it, I wanted to just karate chop the air. |
[694.80 --> 698.52] That was the kind of spooky reaction I had to it. |
[698.60 --> 700.16] Just like, whew, in the air. |
[700.64 --> 700.92] Angry. |
[701.78 --> 703.42] But yeah, it's a good lesson though, isn't it? |
[703.48 --> 706.34] Like set budgets and stuff on your things. |
[706.70 --> 707.32] Do set an alarm. |
[707.44 --> 707.60] Yeah. |
[707.94 --> 708.16] Yeah. |
[708.34 --> 709.06] Budget alarms. |
[709.52 --> 709.88] Observability. |
[709.88 --> 711.32] Yes, yes. |
[711.38 --> 712.68] And you know a thing or two about that, yeah? |
[714.68 --> 715.04] Yeah. |
[715.88 --> 716.24] Okay. |
[716.46 --> 718.34] Who can beat my $1,000 bill? |
[718.68 --> 719.74] Not a $1,000 bill. |
[719.92 --> 721.06] Oh yeah, it was a $1,000 bill. |
[721.14 --> 724.06] But that makes it sound like it was one thing, doesn't it? |
[724.06 --> 725.46] Like a single bill. |
[725.90 --> 727.28] It had $1,000 on it. |
[727.58 --> 728.40] So it's not that. |
[728.54 --> 730.68] It was just paid through bank transfer. |
[731.40 --> 732.66] Okay, who's got another one? |
[733.14 --> 736.72] I have one that could have cost many thousands of dollars. |
[737.00 --> 737.86] Oh, Johnny. |
[737.86 --> 738.94] It wasn't spotted. |
[739.36 --> 739.44] Okay. |
[739.44 --> 745.86] So one of the things you can do with function as a service things like AWS Lambda, for example, |
[746.16 --> 751.08] is that you can trigger a Lambda when you write an object to an S3 bucket. |
[751.36 --> 759.42] Word of advice, do not have your Lambdas write to a bucket that they are themselves responding to. |
[761.32 --> 761.88] Oh. |
[761.88 --> 765.94] Because that's going to give you a very nasty bill. |
[766.46 --> 766.66] Yeah. |
[766.72 --> 768.96] And you will not like what you see. |
[769.60 --> 772.36] So yeah, thankfully, Budget Alarms came to the rescue. |
[772.94 --> 773.20] Uh-huh. |
[773.52 --> 774.04] There you go. |
[774.08 --> 774.80] That's the lesson there. |
[774.80 --> 777.98] So what happens is an object goes in the first time. |
[778.06 --> 779.10] That triggers the Lambda. |
[779.30 --> 784.14] The Lambda then writes something into that same bucket, which then triggers another Lambda. |
[784.40 --> 784.64] Right. |
[784.72 --> 785.96] Which then writes something. |
[786.32 --> 788.88] And like, how quickly does that get out of hand? |
[789.74 --> 790.26] Very quickly. |
[791.02 --> 791.10] Yeah. |
[791.10 --> 799.30] Like, if you want to see how well Lambda scales on your own dime, you can do that. |
[799.30 --> 802.92] And yeah, it'll cost you money very quickly. |
[803.32 --> 803.66] Wow. |
[803.90 --> 804.10] Yeah. |
[804.58 --> 804.90] Yeah. |
[805.02 --> 805.32] Okay. |
[805.68 --> 806.18] Pretty good. |
[806.52 --> 808.78] But yeah, the alerts came to the rescue. |
[809.22 --> 809.56] Nice one. |
[809.66 --> 809.86] Mm-hmm. |
[810.20 --> 810.50] Mm-hmm. |
[810.86 --> 811.42] Okay. |
[811.76 --> 812.86] Anyone else got one for us? |
[813.28 --> 814.78] I've got another infinite loop one. |
[815.08 --> 816.60] Are we allowed to name company names? |
[816.76 --> 817.22] I don't know. |
[817.36 --> 818.82] Maybe it's internal and I shouldn't. |
[818.94 --> 819.10] Yeah. |
[819.22 --> 819.58] I don't know. |
[819.58 --> 823.68] I worked for a certain company which has an orange logo that has a bit of a light flying |
[823.68 --> 826.04] shining behind it, and they man in the middle of the entire internet. |
[826.04 --> 832.58] Now, with that in mind, when I was working for said company and their DDoS team, we didn't |
[832.58 --> 833.16] DDoS people. |
[833.30 --> 834.70] We were protecting against DDoSers. |
[834.80 --> 834.88] Yeah. |
[835.00 --> 835.40] I've wounded. |
[835.74 --> 836.04] I don't know. |
[836.10 --> 836.82] The DDoS team. |
[837.02 --> 839.22] I just suddenly realized, I was like, that's the opposite of what we're doing. |
[839.66 --> 843.22] Now, we were trying to protect, and they have a system, right? |
[843.48 --> 848.06] They've got all these 200 pops or points of presence and thousands and thousands of servers. |
[848.62 --> 851.66] And every single one of these is protecting some of the traffic. |
[851.84 --> 854.06] Each machine can do like 20,000 requests per second. |
[854.06 --> 859.72] And yet they need to be able to actually show the value back to the customer and make the |
[859.72 --> 860.82] sort of decision centrally. |
[861.02 --> 864.52] So you send all the logs somewhere, and they're all being sent to one data center. |
[865.34 --> 869.64] So what you end up with is like, if you're doing globally 10 million requests per second, |
[869.86 --> 872.58] you get 10 million log lines per second in one place. |
[872.98 --> 874.10] Ah, nice. |
[874.10 --> 879.72] Certain customer on a certain point in time, industry and type to be non-disclosed, |
[880.06 --> 884.50] wrote an infinite loop in their client and basically spiked 8 million requests per second |
[884.50 --> 885.88] on top of our normal load. |
[886.00 --> 886.40] Oh, wow. |
