Backend.AI
==========

Backend.AI is a streamlined backend API server that hosts heterogeneous
programming languages and popular AI frameworks.
It manages the underlying computing resources for multi-tenant computation
sessions where such sessions are spawned and executed instantly on demand.

By installing this meta-package, you get the client with command-line interface
by default and optionally you may add the manager and agent using pip extra
tags.

.. code-block:: console

   $ pip install backend.ai
   (installs the common and client libs which includes CLI)
   $ pip install backend.ai[manager]
   (installs the common and client libs with the manager/gateway daemon)
   $ pip install backend.ai[agent]
   (installs the common and client libs with the agent daemon)


Server-side Components
----------------------

If you want to run a Backend.AI cluster on your own, you need to install and
configure the following server-side components.
All server-side components are licensed under LGPLv3 to promote non-proprietary open
innovation in the open-source community.

There is no obligation to open your service/system codes if you just run the
server-side components as-is (e.g., just run as daemons or import the components
without modification in your codes).
Please contact us (contact-at-lablup-com) for commercial consulting and more
licensing details/options about individual use-cases.

For details about server installation and configuration, please visit `our
wiki <https://github.com/lablup/backend.ai/wiki>`_.

Manager with API Gateway
~~~~~~~~~~~~~~~~~~~~~~~~

It routes external API requests from front-end services to individual agents.
It also monitors and scales the cluster of multiple agents (a few tens to hundreds).

* Package namespace: ``ai.backend.gateway`` and ``ai.backend.manager``
* https://github.com/lablup/backend.ai-manager

Agent
~~~~~

It manages individual server instances and launches/destroys Docker containers where REPL daemons (kernels) run.
Each agent on a new EC2 instance self-registers itself to the instance registry via heartbeats.

* Package namespace: ``ai.backend.agent``
* https://github.com/lablup/backend.ai-agent

Kernels
~~~~~~~

A set of small ZeroMQ-based REPL daemons in various programming languages and configurations.

* https://github.com/lablup/backend.ai-kernel-runner
   * Package namespace: ``ai.backend.kernel``
   * A common interface for the agent to deal with various language runtimes
* https://github.com/lablup/backend.ai-kernels
   * Runtime-specific recipes to build the Docker images (Dockerfile)

Jail
~~~~

A programmable sandbox implemented using ptrace-based sytem call filtering written in Go.

* https://github.com/lablup/backend.ai-jail

Hook
~~~~

A set of libc overrides for resource control and web-based interactive stdin (paired with agents).

* https://github.com/lablup/backend.ai-hook

Commons
~~~~~~~

A collection of utility modules commonly shared throughout Backend.AI projects.

* Package namespaces: ``ai.backend.common``
* https://github.com/lablup/backend.ai-common


Client-side Components
----------------------

Client SDK Libraries
~~~~~~~~~~~~~~~~~~~~

We offer client SDKs in popular programming languages.
These SDKs are freely available with MIT License to ease integration with both
commercial and non-commercial software products and services.

* Python (provides the command-line interface)
   * ``pip install backend.ai-client``
   * https://github.com/lablup/backend.ai-client-py
* Java
   * Currently only available via GitHub releases
   * https://github.com/lablup/backend.ai-client-java
* Javascript
   * ``npm install backend.ai-client``
   * https://github.com/lablup/backend.ai-client-js
* PHP (under preparation)
   * ``composer require lablup/backend.ai-client``
   * https://github.com/lablup/backend.ai-client-php

Media
~~~~~

The front-end support libraries to handle multi-media outputs (e.g., SVG plots, animated vector graphics)

* The Python package (``lablup``) is installed *inside* kernel containers.
* To interpret and display media generated by the Python package, you need to load the Javascript part in the front-end.
* https://github.com/lablup/backend.ai-media


Integrations with IDEs and Editors
----------------------------------

* Jupyter Kernel: data scientists' favorite tool
   * Package namespaces: ``backend.ai-integration``
   * https://github.com/lablup/backend.ai-integration-jupyter
* Visual Studio Code Extension
   * Search 'live code runner' among VSCode extensions.
   * https://github.com/lablup/vscode-live-code-runner
* Atom Editor plugin
   * Search 'live code runner' among Atom plugins.
   * https://github.com/lablup/atom-live-code-runner
* IntelliJ / PyCharm plugin
   * Coming soon!
