# Installation Overview

Seldon Core 2 can be installed in various setups to suit different stages of the development lifecycle. The most common modes include:

## Local Environment

Ideal for development and testing purposes, a local setup allows for quick iteration and experimentation with minimal overhead. Common tools include:

* Docker Compose:\
  Simplifies deployment by orchestrating Seldon Core components and dependencies in Docker containers. Suitable for environments without Kubernetes, providing a lightweight alternative.
* Kind (Kubernetes IN Docker):\
  Runs a Kubernetes cluster inside Docker, offering a realistic testing environment.\
  Ideal for experimenting with Kubernetes-native features.

## Production Environment

Designed for high-availability and scalable deployments, a production setup ensures security, reliability, and resource efficiency. Typical tools and setups include:

* Managed Kubernetes Clusters:\
  Platforms like GKE (Google Kubernetes Engine), EKS (Amazon Elastic Kubernetes Service), and AKS (Azure Kubernetes Service) provide managed Kubernetes solutions.\
  Suitable for enterprises requiring scalability and cloud integration.
* On-Premises Kubernetes Clusters:\
  For organizations with strict compliance or data sovereignty requirements.\
  Can be deployed on platforms like OpenShift or custom Kubernetes setups.

By selecting the appropriate installation mode—whether it's Docker Compose for simplicity, Kind for local Kubernetes experimentation, or production-grade Kubernetes for scalability—you can effectively leverage Seldon Core 2 to meet your specific needs.

| -------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `seldon-core-v2-crds`      | Cluster-wide installation of custom resources.                                                                                                                                                                         |
| `seldon-core-v2-setup`     | Installation of the manager to manage resources in the namespace or cluster-wide. This also installs default `SeldonConfig` and `ServerConfig` resources, allowing *Runtimes* and *Servers* to be installed on demand. |
| `seldon-core-v2-runtime`   | Installs a `SeldonRuntime` custom resource that creates the core components in a namespace.                                                                                                                            |
| `seldon-core-v2-servers`   | Installs `Server` custom resources providing example core servers to load models.                                                                                                                                      |
