'''Wikimedia Cloud Services''' ('''WMCS''') provides tools, services, and support for technical collaborators who want to contribute to Wikimedia software projects. Use Cloud Services to host your software tools for the [[meta:Wikimedia movement|Wikimedia movement]], without charge.

[[File:Toolforge_logo.svg|right|frameless|60px|alt=Toolforge|link=Portal:Toolforge]]
 
''[[Portal:Toolforge|Toolforge]]'' is one of the projects hosted by Wikimedia Cloud VPS. It is a shared hosting (platform as a service) environment for volunteers to develop and run [https://admin.toolforge.org/tools tools], [[mw:Manual:Creating a bot|continuous bots]], web services, scheduled jobs, and data analysis.
 
To use Toolforge you will need some programming knowledge, an understanding of Unix command line, and version control via Gerrit and Git.
 
Users of the Toolforge project create so-called "tool" accounts (technically ''service groups'') which allow one or more users to collaborate to manage the software source code, configuration, and jobs for that tool or bot.
 
The Toolforge administrators manage a pool of virtual servers that provide a shared project hosting environment that can be used by Toolforge users. These resources include [[Help:Toolforge/Web|web servers]], [[Help:Toolforge/Database|databases]] and [[Help:Toolforge#Redis|other data storage]], and a [[Help:Toolforge/Grid|distributed job processing system]]. These services provide a reliable and scalable hosting environment for volunteers to develop and operate their tools and bots.
 
For additional documentation and help with Toolforge, see [[Portal:Toolforge]].
 
== Cloud VPS ==
 
[[File:Wikimedia_Cloud_Services_logo.svg|right|frameless|60px|alt=Cloud Services|link=Portal:Cloud VPS]]
 
''[[Portal:Cloud VPS|Cloud VPS]]'' (Virtual Private Server) is a [[:w:Cloud computing|cloud computing]] environment powered by [[:w:OpenStack|OpenStack]]. It offers collaboratively owned collections of virtual private servers. You can use this infrastructure to create and maintain open source software projects that help the [[:meta:Wikimedia movement|Wikimedia movement]].
 
The environment includes access to a variety of data services. Cloud VPS allows developers and system administrators to try out improvements to Wikimedia infrastructure (including MediaWiki), power research and analytics, and host projects that are not viable in the Toolforge environment.
 
Cloud VPS is for the advanced users to get involved in Wikimedia operations and software development. Cloud VPS contains [https://openstack-browser.toolforge.org/project/ many projects], each of which uses one or more instances.
 
Cloud VPS instances must go through a request and approval processes. Instances are not permanent and are reviewed periodically for potential deletion/removal. Cloud VPS instances are resource intensive. Before requesting, explore whether Toolforge or another service will adequately meet your needs.
 
=== How is Cloud VPS organized? ===
 
Cloud VPS is divided into projects. Each project has separate members and administrators who can create and maintain virtual machines ("instances") for use by that project. Each project can have own its own access policies, DNS records, etc.
 
=== What is a Cloud VPS project? ===
 
A project is a unit of privilege separation inside the Cloud VPS environment. Each project has separate management of membership, virtual machines, HTTPS proxies, firewall rules, etc. Examples of projects include [[Portal:Toolforge|Toolforge]] and the [[Nova_Resource:Deployment-prep|Beta Cluster]].
 
===How does Cloud VPS work? ===
 
Cloud VPS is a virtualization cluster and hosts various virtual machines (called instances) using [http://www.openstack.org/software/openstack-compute OpenStack Compute]. This is slightly different from your normal servers that you ssh to (i.e. Toolserver), as virtual machines do not exist physically, but reside inside a much bigger machine called the host machine.  More details about the physical setup of Cloud VPS can be found under [[Portal:Cloud VPS/Infrastructure]].
 
== What is the difference between Cloud VPS and Toolforge? ==
 
Cloud VPS is an [[:w:Cloud_computing#Infrastructure_as_a_service_.28IaaS.29|Infrastructure as a service (IaaS)]] solution. It provides virtual machines, storage, firewall, and HTTPS proxy resources to projects. The members of each individual project are responsible for managing applications, data, runtime, middleware, and operating systems themselves.
 
Toolforge is a [[:w:Cloud_computing#Platform_as_a_service_.28PaaS.29|Platform as a service (PaaS)]] solution. It provides [[Help:Toolforge/Web|web servers]], [[Help:Toolforge/Database|databases]] and [[Help:Toolforge#Redis|other data storage]], and a [[Help:Toolforge/Grid|distributed job processing system]] as managed services that can be used by tools and their maintainers.
 
== Data Services ==
 
''[[Portal:Data Services|Data Services]]'' are a collection of products including private-information-redacted copies of Wikimedia's production wiki databases and access to [[dumps.wikimedia.org|Wikimedia Dumps]]. Use data services to create replicas of the production databases and other data for analysis and experimentation.
 
There are also services to interact with data in a web browser: Quarry and PAWS.
 
=== Quarry ===
 
[[File:Quarry-logo.svg|right|frameless|200px|alt=Quarry|link=meta:Research:Quarry]]
 
''Quarry'' is a public querying interface for [[Help:Toolforge/Database|Wiki Replicas]], a set of live replica SQL databases of public Wikimedia Wikis.  Quarry is designed to make running queries against Wiki Replicas easy. Quarry also provides a means for researchers to share and review each other's queries.
 
Quarry queries are run by individual users. They can be saved and published and forked by other users.
 
To use Quarry you need only a Wikimedia login and a web browsers. Quarry can be used by individuals with understanding along the technical spectrum. A basic understanding of SQL is recommended. Learn about [[Help:MySQL_queries|SQL queries]].
 
=== PAWS ===
 
[[File:PAWS.svg|right|frameless|200px|alt=PAWS|link=PAWS]]
 
''PAWS'' is a Jupyter notebook installation hosted by Wikimedia. PAWS notebooks can be used for creating tutorials, running live code, creating data visualizations, running bots using Pywikibot, and more.
 
PAWS notebooks are maintained by a single user. They can be downloaded and forked by other users.
 
To use PAWS you need only a Wikimedia login and a web browser. PAWS can be used by individuals with understanding along the technical spectrum. A knowledge of Python is helpful, but not required.
