We’re excited to bring the community together for an evening of learning and connection. This time, we'll have a community member from Chainguard sharing a use case and, as usual, an Elastic employee sharing their expertise as well. Come support your fellow developers, learn something new, and meet others who are passionate about search, observability, and security. **Date and Time:** Tuesday, May 19th, from 5:30-7:30 pm EDT **Location:** Elastic Arlington Office - 4100 Fairfax Drive, Ste 500, Arlington, VA 22203 **Agenda:** * 5:30 pm: Doors open; say hi, grab a seat, and eat some food. * 6:00 pm: The SBOM Pile in Your S3 Bucket: Turning Bills of Materials Into a Risk Dashboard; and Watching It Shrink with Chainguard, by Mike Barreta, Senior Manager, Engineering at Chainguard * 6:30 pm: Q&A * 6:40 pm: **Agentic Observability: Next-Gen Alerting and Auto-Detected Significant Events**, by Jason Rhodes, Senior Manager, Software Engineering at Elastic * 7:10 pm: Q&A * 7:20-7:30 pm: Networking & refreshments **Talk Abstracts:** **"The SBOM Pile in Your S3 Bucket: Turning Bills of Materials Into a Risk Dashboard; and Watching It Shrink with Chainguard**" Most organizations now generate SBOMs because someone — EO 14028, a FedRAMP auditor, an ISSM — told them to. They land in an S3 bucket, get versioned, and are almost universally never queried. This talk is about what happens when you finally do. I'll stand up a self-contained Elastic stack, pour in SBOMs (SPDX), SLSA provenance, Sigstore signatures, Grype vulnerability scans, the CISA KEV catalog, and OpenVEX adjudication for 30 container images, and show the queries that only become possible once SBOMs stop being compliance artifacts and start being telemetry: which packages I actually run right now, which CVEs are real exposures versus VEX-suppressed noise, what swapping a stock image for its Chainguard equivalent would buy me, and how much of my CVE list is just stuff I inherited from the base layer. Then the cleanup. The same dashboards on Chainguard images show what disappears when the SBOM is small, the signatures verify, and the advisory feed is active: \~9,000 fewer CVEs and \~2.5 GB saved across 20 image pairs, KEV exposure dropping from 7 hits to 0, compliance pass rate going from 0% to 76.5% against NIST 800-218 / FedRAMP Moderate / SSDF. **Bio:** Mike Barretta leads Chainguard’s public sector solutions engineering team, focused on helping ensure the federal government receives its fair share of the future. Barretta has worked across civilian, defense and intel programs in a variety of roles—software developer, data scientist, solution architect—for a variety of organizations—system integrators, consulting companies, software vendors—with the common purpose of creating and championing technologies and techniques for simplifying the extraction and utilization of information from lots of data. Having witnessed the ever-increasing threats to those systems, Barretta is now focused on methods and mitigations to secure them **Agentic Observability: Next-Gen Alerting and Auto-Detected Significant Events** We're rebuilding Elastic's alerting engine to make alerts more flexible\, more powerful\, and more valuable as data\. Next\-gen alerting rules will run anything ES\|QL supports and capture whatever fields matter to you\, so alerts carry the context you need for real downstream analysis\. And if you'd rather not manage these rules yourself\, AI agents can help\, drafting them from natural language\, recommending tuning and configuration changes\, and reducing noise through deduplication\. On top of this, we're also building a new Significant Events system which automatically builds a continuously updated knowledge base of your incoming data's own metadata. Using this deep understanding, our agentic tools will detect significant events from log patterns, anomalies, and predicted behavior — without you having to create a single rule. **Bio:** Jason Rhodes is a software engineering lead at Elastic, where he works on alerting and observability features. Based in the DC area, he has over 15 years of experience in software development and has been an active contributor to the local tech community — creating and organizing Baltimore NodeSchool and charmCityJS. When he's not writing and reviewing code, he's probably watching too many movies. **Parking:** * The building’s parking garage is operated by Colonial Parking and is located off N.

Come volunteer with us refurbishing donated bicycles so that they can be used again by the community! This event is open to both new and existing volunteers. No mechanical experience is necessary. Note: The warehouse location is in the alley behind 1502 Mt Vernon Ave. Enter through the gray door next to a roll-down garage door. If you drive to the location, be sure to park in the street, not in the alleys or parking lots surrounding the warehouse. And wear clothes you don't mind getting dirty with bicycle grease! Please be aware that volunteers under 18 need a parent or guardian to accompany them to their first volunteer experience and sign a liability waiver, while volunteers under 16 need a parent or guardian to accompany them at all times while volunteering with Vélocity.

We will have open shop hours for anyone to bring their bikes to work on or need help fixing your own bike. We will also have bikes that need to be fixed so you can learn if you like. We will need everyone to sign in when arriving and sign out when leaving so we can keep track of volunteer hours and shop times. Suggested donation of $15 per hour for use of tools and space would be appreciated. Thank you!

This 1962 historical fiction novel, about the life and last days of the titular Artemio Cruz, is considered a milestone of the Latin American Boom that brought us writers such as Mario Vargas Llosa and Gabriel Garcia Marquez. It explores the corruption of Cruz, a former soldier in the Mexican Revolution, by power. Interestingly, the structure of the book is heavily influenced by "Citizen Kane," with Fuentes attempting literary versions of such film techniques as cross-cutting, closeups, and deep focus.

Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.) We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions. Finally, if you plan on sharing a poem, consider how you will do so. Some options include: * Print 5-10 copies to distribute in person * Take and share screenshots in the Discord chat. * Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat. Most importantly, we’re excited to meet you! Catch you on Saturday, Diego / Ian / Cayden / Nate / Otasha / Lia / An

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

The methodology of deploying from a build is now baked into our culture. Take it a touch farther with infrastructure as code and a few extra techniques, and you can reliably deploy to any platform: cloud, on-prem, container, PaaS, and more. Join us as we learn the methodology of GitOps, the critical pieces you need in place, and the elegance of rollbacks with GitOps. You'll leave with a working repo of deployment techniques that doesn't consume any paid tools or container-specific techniques.

We will show how to build custom agents with Microsoft Agent Framework. Attendees will learn how to build and custom host agents when Microsoft Foundry is not a viable option.
