Launched in 2016, MongoDB Atlas was designed to bring MongoDB's developer experience to the cloud while eliminating operational overhead for production environments. Over ten years, Atlas expanded beyond a managed database into a multi-cloud data platform that supports multi-document ACID transactions, Queryable Encryption, native search, and stream processing. The platform introduced Atlas Vector Search in 2023 and acquired Voyage AI in 2025 to embed advanced embedding and reranking models natively. These integrated capabilities address the requirements of retrieval-augmented generation and autonomous AI agents without relying on disparate vector stores or sync pipelines. Atlas now serves more than three trillion queries daily across over 125 AWS, Google Cloud, and Microsoft Azure regions for nearly 70,000 customers.


### [Achieving Near-Linear Training Scalability for Pinterest’s Foundation Models](https://yomu.fyi/post/achieving-near-linear-training-scalability-for-pinterest-s-foundation.md)
- Company: [Pinterest](https://yomu.fyi/company/pinterest.md)

- Type: Problem & solution

Pinterest’s foundation ranking models store approximately 99% of their parameters in embedding tables, causing cross-node NCCL all-to-all communication to severely bottleneck multi-node distributed training. Initial multi-node scaling stalled at 1.21x on four nodes even after adopting AWS Elastic Fabric Adapter for OS-bypass networking. To resolve this, engineers profiled GPU activity with PyTorch Profiler and systematically addressed communication bottlenecks across multiple layers. The team implemented FP8 quantized communications using FBGEMM, balanced table sharding across GPUs, halved embedding dimensions while doubling row counts, and adopted a 2D parallel communication topology alongside PyTorch Distributed Checkpoint. These combined interventions achieved near-linear scaling factors of 3.9x on four nodes and 7.5x on eight nodes across 64 GPUs.

Amazon is investing in next-generation nuclear technology powered by tristructural isotropic (TRISO) fuel particles to satisfy the increasing energy demands of cloud computing and artificial intelligence infrastructure. Each sub-millimeter TRISO particle encloses a high-assay low-enriched uranium kernel within a porous carbon buffer and a three-layer ceramic shell featuring silicon carbide that acts as a robust miniature containment vessel. Testing by the U.S. Department of Energy demonstrated that irradiated particles withstand temperatures of 1600°C for 300 hours without detectable failures. In pebble-bed designs like the X-energy Xe-100 reactor, graphite spheres containing TRISO fuel circulate continuously through the core to enable online refueling, passive heat removal, and modular 80-megawatt deployments at facilities like the Cascade Energy Center.

- Company: [Clickhouse](https://yomu.fyi/company/clickhouse.md)
- Published: Jun 24, 2026
- Type: Problem & solution

Visa used ClickHouse Cloud to modernize reporting on Authorize.net payments data, replacing multi-day analyst-led turnaround with natural-language queries for internal teams. The solution pairs LibreChat, an open-source conversational interface, with the ClickHouse MCP server and runs on ClickHouse Cloud on AWS, allowing agents to explore and query a roughly 40 PB data footprint containing millions of rows. ClickHouse materialized views pre-compute and incrementally update results, reducing scanned data and bringing example analyses down to 100–200 milliseconds, with reported speedups of roughly 30–70 times. The platform also uses encrypted transfers, Amazon S3, VPC PrivateLink, change data capture, and federated access controls, while Visa reports identifying millions of dollars in revenue risk and reclaiming 8–10 hours per user each week.


### [Appcues delivers personalized customer engagement with ClickHouse Cloud](https://yomu.fyi/post/appcues-delivers-personalized-customer-engagement-with-clickhouse-clou.md)
- Company: [Clickhouse](https://yomu.fyi/company/clickhouse.md)
- Published: Jun 18, 2026
- Type: Problem & solution

Appcues replaced an analytics stack that included Snowflake and Airflow after rising scale pushed queries to 20 seconds or more and limited reports to 10-minute windows. The company evaluated ClickHouse Cloud on AWS for real-time segmentation, exporting Snowflake data to Parquet in S3 and testing complex email segments with nested conditions, historical events, and negative logic. Production events now pass through Kafka and a clickwriter consumer, while a clickclient library built on Elixir’s Ecto generates controlled ClickHouse queries; SharedReplacingMergeTree, table engines, and materialized views were tuned during a one-year migration. Across 1.31 PB and 410 billion events, P95 queries fell below two seconds, ingestion latency dropped to about five seconds, and analytics costs decreased 23%, while new funnel reports and AI-powered insights were added.

- Type: Announcement

Postgres managed by ClickHouse, which entered public beta in May, received a broad update covering console operations, per-service RBAC, Terraform, Stripe provisioning, ClickPipes migrations, billing, capacity reservations, and extensions. The redesigned console adds service health, resource, and query views, while RBAC provides View and Manage roles across the console and public REST API; the alpha Terraform provider covers lifecycle operations including resizing, HA, replicas, restore, and password rotation. Postgres-to-Postgres ClickPipes now automate schema migration, usage is integrated into ClickHouse Cloud’s metering and billing, and AWS capacity reservations are allocated dynamically across availability zones. Underneath, pg\_clickhouse and pg\_stat\_ch moved to the header-only clickhouse-c library, removing a C++ exception conflict, using Postgres memory contexts, and reducing the x86-64 Linux extension binary from 4.9 MB to 1.4 MB; the update shipped less than a month after beta, with Terraform and extensions still evolving.


### [Cisco Talos empowers threat researchers while reducing TCO by 75% with ClickHouse Cloud](https://yomu.fyi/post/cisco-talos-empowers-threat-researchers-while-reducing-tco-by-75-with.md)
- Company: [Clickhouse](https://yomu.fyi/company/clickhouse.md)
- Published: Jun 15, 2026
- Type: Problem & solution

Cisco Talos operates a threat-intelligence reputation service that classifies file hashes from Cisco product telemetry, enabling researchers to make security decisions about benign and potentially malicious artifacts. Previously, a custom pipeline moved data from Databricks Delta and S3 through EKS, where staging and aggregated tables supported an API; the self-managed design retained about a petabyte of compressed, replicated data on 32 high-compute nodes. The team rebuilt the system in four phases, using Terraform, SSO/SAML, sharded ClickPipes for a 12-month backfill, shadow traffic, and a validated cutover to ClickHouse Cloud on AWS. The resulting architecture uses EventBridge, SQS, ClickPipes, SharedMergeTree, object storage, and AWS PrivateLink, delivering less than a minute of queue lag, zero data loss, a 100% response match across more than 1,000 hashes, zero downtime, roughly 90% lower storage costs, and about 75% lower TCO while reclaiming over 300 engineer hours annually.

Attendees can also join technical conversations, receptions, and a 14-day Databricks on AWS Marketplace trial with $400 in usage credits.


### [EC2’s formally verified “isolation engine” provides mathematical assurance of virtual-machine isolation](https://yomu.fyi/post/ec2-8217-s-formally-verified-8220-isolation-engine-8221-provides-mathe.md)
- Company: amazon.science
- Author: Dominic Mulligan, Nathan Chong
- Published: Jun 10, 2026
- Type: Announcement

AWS has introduced M9g and M9gd EC2 instances powered by Graviton5 CPUs, featuring the formally verified Nitro Isolation Engine to enforce virtual machine isolation. To prove the engine's correctness, engineers developed 330,000 lines of machine-checked mathematics using the Isabelle/HOL proof assistant. The system architecture separates hypervisor policy from isolation mechanisms, requiring the deprivileged Nitro Hypervisor to route all guest state modifications through the minimal Rust-based engine. Functional verification uses a restricted language subset called micro Rust, Separation Logic contracts specifying total correctness, and weakest-precondition calculus from the open-source AutoCorrode library. Finally, high-level transition relations and noninterference proofs ensure that memory integrity and guest confidentiality are preserved across every execution step.

- Type: Problem & solution

Slack evolved its Slack AI serving infrastructure across multiple phases to handle enterprise LLM workloads reliably and securely. The initial deployment on AWS SageMaker provided zero-knowledge escrow VPC isolation and FedRAMP compliance, but engineers faced scaling latency, GPU scarcity, and significant operational overhead. Slack then migrated live traffic to Amazon Bedrock to leverage managed Model Units and eliminate model release lag without customer-facing incidents. However, fixed Provisioned Throughput commitments and regional peak traffic variations created persistent underutilization challenges. Consequently, Slack expanded into a multi-cloud orchestration architecture that normalizes disparate provider APIs, integrates unified cross-cloud telemetry, and routes traffic dynamically around latency spikes and outages.


### [How flat is replacing fat in AWS data center networks](https://yomu.fyi/post/how-flat-is-replacing-fat-in-aws-data-center-networks.md)
- Company: amazon.science
- Author: Giacomo Bernardi, Ratul Mahajan, Seshadhri Comandur
- Published: May 28, 2026
- Type: Problem & solution

Traditional data center networks rely on hierarchical fat-tree topologies, which introduce overhead, upper-layer congestion, and vulnerability to router failures. Although flat random networks theoretically maximize route diversity and resilience, routing computation and cabling complexity historically made them impractical for physical data centers. AWS addressed these constraints by introducing Resilient Network Graphs, a quasi-random architecture powered by a passive optical device called ShuffleBox and a routing algorithm named Spraypoint. Spraypoint sprays packets across random neighbors toward designated waypoints, unlocking twice as many independent paths while operating within commodity router memory limits. Adopted as the default architecture across new AWS facilities, this design reduces router counts by 69%, lowers projected network power consumption by 40%, and increases throughput by up to 33%.

### [Beyond the Menu Tree: How Yelp Built a Smarter Customer Success Chatbot with AI](https://yomu.fyi/post/beyond-the-menu-tree-how-yelp-built-a-smarter-customer-success-chatbot.md)
- Company: [Yelp](https://yomu.fyi/company/yelp.md)
- Author: Lina Lee, Machine Learning Engineer; Nelson Lee, Engineering Manager
- Published: May 27, 2026
- Type: Problem & solution

Yelp transitioned from a legacy customer support chatbot that relied on rigid phrase matching and static menus to a retrieval-augmented generation system. The updated architecture classifies incoming queries using a large language model to route users into one of five specialized workflows, including QA, Billing, Refund, Cancel, and Review. For general QA, the system uses FAISS to search an in-memory vectorstore built exclusively from article metadata such as titles, summaries, and headers rather than raw article text. Retrieved articles are supplied to the language model as prompt context, followed by automated validations for safety, character limits, and hallucinated hyperlinks. In production A/B testing, this metadata-driven design doubled the chatbot resolution rate while achieving approximately 94% recall@5.


### [Protecting your Supabase projects from npm supply chain attacks](https://yomu.fyi/post/protecting-your-supabase-projects-from-npm-supply-chain-attacks.md)
- Company: [Supabase](https://yomu.fyi/company/supabase.md)
- Author: katerina\_skroumpelou
- Published: May 26, 2026
- Type: Explainer

The post explains why npm supply-chain attacks matter to Supabase projects: Edge Functions, the Supabase CLI, and packages including supabase-js, @supabase/ssr, and @supabase/server all depend on npm. Attackers can compromise maintainers, register typosquats, or exploit build pipelines; once malicious code reaches node\_modules, lifecycle scripts may read environment variables, cloud metadata, tokens, kubeconfig, and SSH keys. The proposed defense is layered: upgrade to pnpm 11, increase minimumReleaseAge to several days, pin sensitive dependency versions, commit and review lockfiles, disable or allowlist install scripts, verify package names, and pin GitHub Actions to full commit SHAs. Supabase is publishing a canonical security guide, hardening its GitHub Actions, adding secret-handling warnings to API documentation, and coordinating communications; the post also recommends rotating credentials after a potentially compromised install and using scanners as supplementary defense.


### [How Partition Access Visualizations Reduced our Data Lake S3 Cost by 33%](https://yomu.fyi/post/how-partition-access-visualizations-reduced-our-data-lake-s3-cost-by-3.md)
- Company: [Yelp](https://yomu.fyi/company/yelp.md)
- Author: Nick Del Nano, Data Streaming
- Published: May 21, 2026
- Type: Problem & solution

Data teams at Yelp struggled to identify table consumers and track how datasets were accessed across their petabyte-scale data lake. To solve this, the team built a usage attribution system using Amazon S3 server access logs to visualize time-based partition keys against access timestamps and IAM roles. These visualizations revealed distinctive patterns for daily batch jobs, backfills, and ad hoc queries, guiding migrations of thousands of tables to Apache Iceberg format. Furthermore, Yelp implemented a Default Access Retention strategy gated by IAM bucket policies to prevent accidental queries from resetting S3 Intelligent Tiering transitions. Combining these granular usage insights with targeted S3 storage classes reduced Yelp's S3 storage costs by 33 percent.
