+## Huly Virtual Network
+
+The platform features a distributed network architecture that enables scalable, fault-tolerant communication between accounts, workspaces, and nodes. The [Huly Virtual Network](./network/README.md) provides:
+
+- **Distributed Load Balancing**: Intelligent routing across multiple nodes using consistent hashing
+- **Multi-Tenant Architecture**: Secure workspace isolation with role-based access control
+- **Fault Tolerance**: Automatic failover and recovery mechanisms
+- **Real-time Communication**: Event-driven architecture with broadcast capabilities

+# Huly Virtual Network
+
+A distributed, scalable virtual network architecture for the Huly that enables fault-tolerant performance communication.
+
+## 🚀 Overview
+
+The Huly Virtual Network is a sophisticated distributed system designed to handle enterprise-scale workloads with the following key capabilities:
+
+- **Distributed Load Balancing**: Intelligent routing to key components across multiple phytsical nodes.
+- **Multi-Tenant Architecture**: Secure isolation of containers for user sessions/search engines/transaction processors.
+- **Fault Tolerance**: Automatic failover and recovery mechanisms
+- **Scaling**: Horizontal and vertical service scalling.
+- **Real-time Communication**: Event-driven architecture with broadcast capabilities between containers.
+
+## Network Architecture Components
+
+### Agents & Containers
+
+Agent is a top of the rock for containers. Containers are work horses for any application build on top of Huly Network, they could be started, located and used.
+Every container could be located by its {kind + uuid} or using a labeling system. After being found anyone could send a message to container and ask for some activity.
+
+Container's could be communicated two ways:
+
+1. Anyone could send a message to container using network.
+2. A request/response connection could be established to container using network.
+
+Network provide a references to containers, if container is references it will be active until reference is exists. If there is no references to contaienr, it will be keept for some timeout and closed.
+
+Agents provide a list of container kinds they support to be started to Huly Network, manage them and provide live/monitoring and networking capabilities.
+Communication to containers are managed by Huly Network.

+## Building Huly on top of Huly Network
+
+Huly could be managed by following set of container kinds, `session`, `query`, `transactor`.
+
+- session -> a map/reduce/find executor for queries and transactions from client.
+- query -> a DB query engine, execute `find` requests from session and pass them to DB, allow to search for all data per region. Should have access to tables of account -> workspace mapping for security.
+- transactor -> modification archestrator for all edit operations, do them one by one.
