If you run a modern application stack, you probably use at least three different database engines. PostgreSQL for your application data. MongoDB or another document store for unstructured content. Valkey (or Redis) for caching and session storage. Kafka for event streaming. Maybe MySQL for a legacy service that nobody wants to migrate.

Each engine runs on a different managed provider. Each provider has its own dashboard, its own CLI, its own billing, its own alerting system, its own way of handling backups, its own access control model. You pay five bills, manage five sets of credentials, and context-switch between five different interfaces when something goes wrong at 2 AM.

We built FoundryDB to solve this problem: one platform for all your database engines, with a single API, a single dashboard, and a single bill.

Testing against realistic data is the difference between catching bugs before production and catching them in production. But getting a faithful copy of your production database into a staging environment usually means writing export scripts, waiting for dumps to transfer, provisioning infrastructure, and importing the data. For a 100 GB PostgreSQL database, that process can take hours and requires someone to babysit it.

FoundryDB's fork endpoint eliminates this entire workflow. One API call creates a fully independent copy of your database, running on its own VM with its own credentials, restored from a backup of the source service. The source database is never touched. The fork is provisioned, restored, and ready for connections in minutes.

Every RAG system needs the same boring middle layer: watch a table for changes, call an embedding API, write vectors back, handle retries, manage batches, build indexes, schedule cron jobs, and pray nothing drifts out of sync at 3 AM. FoundryDB's managed embedding pipelines eliminate that entire layer. You configure a pipeline, and your PostgreSQL data gets auto-vectorized with an HNSW index, ready for similarity search.

No ETL scripts. No cron jobs. No model orchestration code.

When we started building FoundryDB, one of the first decisions was where to run the infrastructure. The answer shaped everything that followed: we chose to build exclusively on European cloud providers, starting with UpCloud, a Finnish infrastructure company operating under EU law.

This was not a marketing decision. It was a legal and architectural one. If you store customer data in databases, the jurisdiction of the infrastructure underneath those databases determines what legal regime governs access to that data. For many organizations in Europe, this distinction is no longer optional.

Event-driven architecture has moved from buzzword to baseline. If you are building microservices, real-time analytics, or data pipelines in 2026, Kafka is likely somewhere in the stack. The challenge is not whether to use it, but how to operate it without drowning in ZooKeeper configs, TLS certificate rotation, and broker rebalancing.

This post covers practical streaming patterns on FoundryDB's managed Kafka: topic design, partitioning strategies, consumer groups, schema enforcement, and monitoring. All examples use FoundryDB's Kafka 4.0 with KRaft mode and SASL/SCRAM authentication.

Your AI coding assistant can write SQL, generate migrations, and debug queries. But when you need a database to run that code against, you leave the conversation, open a dashboard, click through a provisioning wizard, copy credentials back into your editor, and resume. That context switch breaks flow.

FoundryDB's MCP server removes it. Your AI assistant provisions databases, retrieves connection strings, checks metrics, and triggers backups without you ever leaving the conversation.

MongoDB is one of the most popular document databases in the world, but running it in production comes with real operational overhead: replica set initialization, oplog sizing, backup orchestration, WiredTiger cache tuning, and disaster recovery planning. FoundryDB handles all of this out of the box, so you can focus on your application logic.

This post walks through provisioning a MongoDB service, running aggregation pipelines against it, and recovering from data loss using oplog-based point-in-time recovery.

Every application eventually outgrows LIKE '%query%'. Once your product catalog, help center, or log pipeline crosses a few million documents, you need an inverted index, not a sequential scan. OpenSearch provides exactly that: full-text search with relevance scoring, custom analyzers, aggregations, and a visualization layer built in.

The hard part is running it. JVM heap tuning, cluster formation, TLS certificate management, shard rebalancing, and snapshot configuration turn a "quick search feature" into a permanent ops project. FoundryDB removes all of that. You get a managed OpenSearch 2.19 cluster with TLS, authentication, automated snapshots, and monitoring out of the box.

This guide walks through deploying OpenSearch on FoundryDB and building production-quality search: from provisioning to index design, full-text queries, custom analyzers, and aggregations.

Most PostgreSQL workloads are read-heavy. Dashboards, reporting queries, search, and API endpoints that serve cached-but-still-queried data all put pressure on a single primary. Vertical scaling helps, but at some point you are paying for CPU that only writes use while reads compete for the same connections.

Read replicas solve this by giving you additional PostgreSQL nodes that serve read queries from a continuously updated copy of your data. On FoundryDB, adding a replica takes one API call and a few minutes of provisioning time.

Reactive autoscaling has a fundamental problem: it waits for something to go wrong. Your database hits 95% CPU, the autoscaler wakes up, requests a resize, and for the next few minutes your application eats latency while the new resources come online. If your traffic is predictable (and most production traffic is), this delay is avoidable.

FoundryDB's predictive autoscaling engine learns your workload's seasonal patterns and scales your database before demand spikes arrive. It combines real-time metric thresholds with historical baselines, anomaly detection, and configurable cost limits so you stay fast without overspending.
