 🧑‍💻 Written in Go and C++, Milvus implements hardware accelaration for CPU/GPU to achieve best-in-class vector search performance. Thanks to its [fully-distributed and K8s-native architecture](https://milvus.io/docs/overview.md#What-Makes-Milvus-so-Scalable), Milvus can scale horizontally, handle tens of thousands of search queries on billions of vectors, and keep data fresh with real-time streaming updates. Milvus also supports [Standalone mode](https://milvus.io/docs/install_standalone-docker.md) for single machine deployment. [Milvus Lite](https://milvus.io/docs/milvus_lite.md) is a lightweight version good for quickstart in python with `pip install`.
