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.

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.

Our NEIGHBORHOOD GEMS series features emblematic meals from around the world. This series shines a light on local restaurants and is designed to bring together inquisitive foodies and dishes that are unique and oh so worth a trip on roads less traveled! Join us for authentic Greek & Turkish dishes at ***Smyrna***! **From Northern Virginia Magazine** Chef Zeynep Güngören hails from Izmir, the third largest city in Turkey. Izmir, known as Smyrna until 1930, is located on the Aegean Sea. Not surprisingly, given its location, Greece and Turkey have squabbled over the city for millennia. The ancient site was once famous as one of Greece’s most important ports and later became a key site in Alexander the Great’s empire. Even today, its residents share strong influences of both countries. An aesthetician by trade, Güngören is new to the world of the professional kitchen. But after taking a first bite of her tzatziki, moussaka, or baklava, diners will realize that this isn’t an inadequacy but a stroke of luck for them to be able to discover this fresh talent. Zeynep and her husband, Alp Güngören, opened Smyrna Restaurant and it has attracted a hushed buzz among area food obsessives. It’s not just the ingredients on plates that are fresh — Alp believes that Smyrna is the only restaurant in the United States serving the Izmir-inspired, pan-Aegean cuisine in which he and his wife trade. For diners who can’t decide between Greek and Turkish for their next meal out, Smyrna has tastes of both, but national borders shouldn’t dictate what one orders. Zeynep cooks the food of her Aegean family, which combines the influences of her Greek grandmother and her parents, including her Turkish chef father. “Our goal is to transport our guests to the warm shores of the Aegean,” says Alp. The young couple settled in the U.S. five years ago, with Alp previously working at Michelin-recognized Levantine restaurant Ala and Turkish restaurant Ottoman Taverna, both in DC. It was his dream to have a business of his own with his wife’s big flavors on full display. This is a service to us, complete with the well-versed front-of-house team he manages. To attract neighborhood diners, the couple, who also are parents to two young children, offer low-cost prix fixe menus that make every day at Smyrna feel like Restaurant Week. For $35, dinner guests are treated to four courses known as the Aegean Odyssey. It’s a good starting point, but reasonable prices on the á la carte menu mean that for most, it’s worth a few more dollars per person to order dishes like the spread sampler. I always thought tzatziki was a little boring, more worthy of inclusion in a gyro than as a stand-alone appetizer. That was before I tried Zeynep’s version. Singing with mint and with a light pucker of fresh yogurt, the cucumber dip tastes new. Fewer diners will be familiar with Turkish atom, a crave-worthy portion of labneh (strained yogurt) that’s given a spicy topping of sundried chiles in sanguine-looking melted butter. Among the five other dips on the menu, hummus is the only forgettable entry, lacking in both acidity and garlic. But others make up for it. The baba ghanoush (on the menu as baba-ghannush) is exceptionally creamy, thanks to the addition of Greek yogurt to smooth out the texture of the charred eggplant with tahini. Pembe sultan pairs finely chopped beets with labneh and garlic for a sweet surprise that never verges on dessert. Her dolmades will win over even a diner who dislikes grape leaves. The warm center of rice is dotted with pine nuts for texture and sweet dried black currants. They’re served in pools of tangy yogurt sauce that enliven each comforting bite. Whatever starter diners choose, they should add the saganaki for the entertainment alone. The server who lit our portion of stretchy kasseri cheese aflame with a dousing Metaxa, a Greek muscat-blended spirit, looked genuinely gleeful to play with fire for us. The lemon-tempered result was every bit as delightful on the palate. Among entrées, moussaka, with its pairing of melty kashkaval cheese and bechamel sauce, is a lush, mouth-coating extravaganza of texture and flavor. The eggplants and potatoes layered with ground beef are tender, but never mushy. A bowl stacked with petite Turkish manti — beef-filled dumplings in dueling garlicky yogurt and spicy tomato-based sauce — is just as satisfying, in part thanks to a shower of mint. But an argument could be made to skip the entrées and order multiple starters and desserts. The chocolate baklava isn’t just filled with chocolate, it is made with layered leaves of chocolate phyllo dough, then finished with chocolate ice cream. Excessive? Yes, in the best possible way. The pastry is far from dry but doesn’t suffer from even a hint of the waterlog that baklavas often do. It crackles and shatters outside and oozes from within. But to stop there would mean missing out on the other pleasures at hand. Chocolate fiends could go for another application of their favorite vice and try the pasta sokolatina — Greek chocolate cake. A layer of cream rests atop pleasantly rugged cake, all enrobed in ganache. Ask the Güngörens, though, and they will say to try the rice pudding. It’s emulsified with mastic, a plant resin that’s responsible for the gummy chew of Turkish Delight, among other desserts. The cinnamon-scented, al dente grains of rice in a thick cream are oven-baked for a browned top, then served chilled. The neighborhood has welcomed Smyrna with both OpenTable Diners’ Choice and NextDoor Neighborhood Fave awards, and it can be a challenge to land a table at the small restaurant on weekends. For that reason, the Güngörens are already pondering a move to a larger spot. Zeynep says the greatest reward is that she’s making her family proud. And she’s doing it by sharing their culture with her new neighbors, transporting them, for a moment, to the Aegean coast. **Check out the menu** **[here](https://restaurantsmyrna.com/dinner-menu)** Separate checks will be arranged in advance.

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!
