Corey: This episode is sponsored in part by Catchpoint. Look, 80 percent of performance and availability issues don’t occur within your application code in your data center itself. It occurs well outside those boundaries, so it’s difficult to understand what’s actually happening. What Catchpoint does is makes it easier for enterprises to detect, identify, and of course, validate how reachable their application is, and of course, how happy their users are. It helps you get visibility into reachability, availability, performance, reliability, and of course, absorbency, because we’ll throw that one in, too. And it’s used by a bunch of interesting companies you may have heard of, like, you know, Google, Verizon, Oracle—but don’t hold that against them—and many more.

Pete: Hello, and welcome to the AWS Morning Brief: Whiteboard Confessional. You are not confused. This is definitely not Corey Quinn. This is Pete Cheslock. I was the recurring guest. I've pushed Corey away, and just taken over his entire podcast. But don't worry, he'll be back soon enough. Until then, I'm joined by a very special guest, Jesse DeRose. Jesse, want to say hi?

Jesse: Howdy everybody.

Pete: Jesse and I are two of the cloud economists that work with Corey here at The Duckbill Group, and I convinced Jesse to come and join me today to talk about a new Amazon service that we had the pleasure—mm, you be the judge of that—of testing out recently, a service called Amazon Detective. This is a new service that I want to say was announced a couple of weeks ago, actually longer than that because, as you'll learn, it took us a little while to actually get a fully up and running version of this going, so we could actually do a full test on it. But as you can imagine, we get a chance to try out a lot of new Amazon services. And when we saw this service come out, we were pretty excited. Jesse, maybe you can chat a little bit about what piqued your interest when we first heard of Amazon Detective.

Jesse: So, we here do a lot of analysis work with VPC Flow Logs. There's so much interesting data to be discovered in your VPC Flow Logs, and I really enjoy getting information out of those logs. But ultimately, digging into those logs via AWS’s existing services can be a bit frustrating; it can be a bit time-consuming in order to go through the administrative overhead to analyze those logs. So, for me, I was really excited about seeing how AWS Detective automatically allowed us to dig into some of that data, ideally more fluidly, or more organically, or naturally, to get at the same information with, ideally, less hassle.

Pete: Exactly. So, for those that have not heard of AWS Detective yet, I'm just going to read off a little bit about what we read on the Amazon documentation that actually got us so excited. They talked a lot about these different security services like Amazon GuardDuty Macie, Security Hub, and all these partner products. But finding this central source for all of this data was challenging.

And one of the things they actually called out which got us really excited is these few sentences. They said, “Amazon Detective can analyze trillions of events from multiple data sources such as Virtual Private Cloud (VPC) Flow Logs, AWS CloudTrail, and Amazon GuardDuty, and automatically creates a unified, interactive view of your resources, users, and the interactions between them over time.” It was actually this sentence that got us really excited because, as Jesse mentioned, we spend a lot of time trying to understand our clients’ data transfer usage. What is talking to what? Why is there charge for data transfer between certain services? Why is it so high? Why is it growing? And we spend, unfortunately, a lot of time digging around in the VPC Flow Logs. So, when we saw this, we got really excited because—well, Jesse, how do we do this today? How do we actually glean insight from Flow Logs?

Jesse: It's a frustrating process. I feel like there has got to be a better way for us to get this information from a lot of our clients, and every single time we have to ask our clients to send over or share these VPC Flow Logs. There's that little wince of the implied. “I’m so sorry that we have to ask you to do it this way,” because it's doable, but it requires sinking data between S3 buckets, creating and running Athena queries, there's lots of little pieces that are required to build up to the actual analysis itself. There's no first-class citizens when it comes to analyzing these logs.

Pete: It's really true. And Athena, the Data Factory—the Data Glue—what is it? Glue. You have to create a Glue Catalog. It's just a lot of work when we're really just trying to understand who and what are the top producers, consumers of data that is likely impacting spend for a client.

So, we saw this and we thought to ourselves, “Wow, that one sentence it put in the list, it said, ‘The interactions between all of these resources and users over time.’” We got really excited for this. We also got excited because, of course, we love understanding how much things cost, but the pricing for Detective, it didn't seem that crazy. I mean, it's not great, but it's all based on ingested logs, which they don't really describe. So, our assumption is that if you send it your VPC Flow Logs, or CloudTrail logs, or whatever, you're going to pay for those on top of probably already paying for them today. So, that could be a deal-breaker for some clients out there.

Jesse: That's the thing that was super frustrating for me, or super interesting for me is that AWS Detective, in terms of pricing and in terms of technology and capability, doesn't replace any of these other components. It is additive, which, generally speaking, I think is great, but when you start looking at it from a price perspective, that means that you're going to pay for CloudTrail logs, and VPC Flow Logs, and GuardDuty, and Macie, and all of these other services, and now you're going to pay for AWS Detective on top of that. So, it feels like you're paying twice for a lot of these services, when you could do a lot of the same analysis work yourself. And it's probably not going to be as clean to do it yourself in terms of building out the Glue Catalogs that we talked about building out, Athena tables and queries. But ultimately, it may be less expensive because it's not ultimately paying for all these additive services on top of each other.

Pete: Exactly. I think we're definitely not being fair to the Amazon Detective product teams because we're trying to use this service, or we're hoping this service solves a really specific painful use case for us. And really, it's just based on what we found in their public-facing marketing.

So, how does this actually work? Well, we found some really great information online via Amazon. They did a great job documenting how this all works. Essentially, you enable Amazon Detective, and you enable CloudTrail, and VPC, and GuardDuty, you have to enable it in multiple accounts, and Jesse can talk a little bit more about some of the caveats we ran into just setting it...
