## Core Components

#### 1. Flexible AI infrastructure with VKS

* **VKS (GreenNode Kubernetes Service)** is a fully managed Kubernetes service.
* Integrated GPU support, autoscaling, resource monitoring, and security.
* Optimized for AI workloads that require GPU, and equally suitable for deploying web applications, microservices, and large-scale backends.
* Lets enterprises deploy applications quickly without building and maintaining their own infrastructure.

#### 2. Vector Database as a service

* Supports PostgreSQL (**pgvector**) and **OpenSearch** as vector databases.
* Delivered as a **managed service** — no infrastructure to manage.
* Enables rapid deployment of **RAG (Retrieval-Augmented Generation)** architectures.
* Helps GenAI models understand and use enterprise data in context.

#### 3. Comprehensive AI Platform

* Provides an environment to **experiment (notebook)**, **fine-tune**, and run **inference** on AI models directly on GreenNode GPU infrastructure.
* Integrates with storage services such as **vStorage** to store training data, model registry, and outputs.
* **Fine-tune** capabilities are currently under development (coming soon).
* Lowers technical barriers and shortens time to deployment.

#### 4. vStorage – Efficient AI storage

* **vStorage** is an **S3-compatible object storage** service optimized for AI workloads.
* Suitable for storing training data, model checkpoints, model registry, and inference output.
* Integrates easily with components such as AI Platform, VKS, and popular training tools.

#### 5. AI Gateway – Centralized routing and monitoring

* A single access point for multiple AI models, with intelligent routing and caching to optimize performance and cost.
* Tracks access, generates audit logs, and monitors usage behavior through metrics and alerts.
* Integrates guardrails to control content and keep AI safe in production.

#### 6. Model-as-a-Service

* Provides access to a wide range of leading **GenAI models** such as GPT, Claude, Gemini, and DeepSeek through a single unified API.
* Includes both open-source models and models optimized for Vietnamese.
* The service is currently being finalized (coming soon).
* Shortens integration time so enterprises can experiment and bring AI into production quickly.

#### Core Value for Enterprises

* Accelerate the GenAI adoption journey without a dedicated in-house AI team.
* Remove infrastructure overhead and optimize AI operating costs.
* Strengthen control, security, and flexibility when integrating AI into digital products.

The GreenNode AI Stack is an ideal foundation for enterprises to build and scale GenAI applications safely, efficiently, and sustainably.
