System Architecture Overview ### MSA Service Composition enVector is composed of five core service roles (Endpoint, Backend, Orchestrator, Shaper, and Compute). Compute can be scaled out to multiple instances as needed. ``` SDK (pyenvector) - client-side HE encrypt/decrypt | | gRPC :50050 v +-----------+ | Endpoint | +-----------+ | | gRPC :50051 v +----------+ +-----------+ +--------------+ | Shaper | <-------> | Backend | --------> | Orchestrator | +----------+ :50056 +-----------+ :25121 +--------------+ | | | | +------+-----+ gRPC | :25123 | | :5432 | :59000 v | +------------+ +-----------+ +-----------+ | | PostgreSQL | | MinIO/S3 | | Compute | (1..N) | +------------+ +-----------+ +-----------+ | | | | +----------------+-----------+ EVI Library (shared storage) (C++ / CGO) ``` | Service | Role | Default Port | | ------------ | ------------------------------------------------------------ | --------------------------- | | Endpoint | Receives client requests, authentication, routing | 50050 (gRPC), 8080 (Health) | | Backend | Metadata management, vector indexing, DB/Storage integration | 50051 | | Orchestrator | Coordinates Compute nodes, schedules jobs | 25121 | | Shaper | Handles data partitioning/merging (Split/Merge) | 50056 | | Compute | Performs vector operations and search (CPU/GPU) | 25123 | ### Docker Compose File Structure | Category | File | Purpose | | ------------------- | ----------------------------- | -------------------- | | Core MSA | `docker-compose.envector.yml` | Five core services | | Core infrastructure | `docker-compose.infra.yml` | PostgreSQL, MinIO | | Compute override | `docker-compose.gpu.yml` | GPU Compute override | > Optional operational/security components are coming soon. *** ## 2.

Production Setup Guide Items to verify before deploying to production. ### Security Hardening * [ ] **Enable DB SSL:** `ENVECTOR_DB_SSL=require` * [ ] **Storage HTTPS:** `ENVECTOR_STORAGE_SECURE=true` (requires TLS certificate configuration) * [ ] **Change passwords:** Set `ENVECTOR_DB_PASSWORD`, `ENVECTOR_STORAGE_PASSWORD`, and other credentials to strong values ### License * [ ] **Place the license token:** Put the `token.jwt` file in the Docker Compose execution directory * [ ] Verify that the `ENVECTOR_LICENSE_TOKEN` path is correct --- # Agent Instructions This documentation is published with GitBook.

Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.envector.io/1.4.x/operations-and-management/server-environment.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
