== Google Summer of Code 2014 ==

[http://www.openstack.org/software/ OpenStack] is applying as a mentoring organization for the [http://www.google-melange.com/gsoc/homepage/google/gsoc2014 2014 Google Summer of Code]. Check [https://developers.google.com/open-source/soc/ Google Developers site] for more information on how the program works.
We need to get in this time!

Link to call for participation: [http://google-opensource.blogspot.com/2014/02/mentoring-organization-applications-now.html here]

Link to FAQs: [http://www.google-melange.com/gsoc/document/show/gsoc_program/google/gsoc2014/help_page here]

=== What is Openstack? ===

[http://www.openstack.org/software/ Openstack] is an open-source IaaS cloud computing platform. Its mission is to provide a flexible solution for both public and private clouds of any size, and for this matter two basic requirements are considered: clouds must be simple to implement and massively scalable.

To meet these principles OpenStack is divided into different components that work together. It's [http://www.openstack.org/software/openstack-compute/ computing], [http://www.openstack.org/software/openstack-storage/ storage], [http://www.openstack.org/software/openstack-networking/ networking], and all the other bits that help make this project, '''The Cloud'''.

OpenStack is [http://i.imgur.com/gAyoiF8.png continuously growing] and new and exciting projects are being discussed everyday.

We encourage new contributors to participate and help us make OpenStack the most complete, reliable and flexible open-source cloud service!

=== Communication ===

Get in touch with mentors and students through the [http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev openstack-dev mailing list].

Also, you can find us at IRC in #openstack-gsoc at irc.freenode.org.

=== Ideas ===

Here are some project suggestions students can choose for their applications. This doesn't mean students have to stick strictly to this list; don't hesitate in propose projects by your own. For the latter, it would be great if you could submit a draft proposal and a estimated timeline.

When writing your proposal, try to estimate your timeline to fit the 4 month period of GSoC coding. Also, take into account that '''GSoC does not consider other projects than coding''', so other ideas (like community tasks or i18n efforts) are not suitable for this internship.

'''Click on the proposed project that caught your attention to get the details about the assumed knowledge, the project goals and more details related to it.'''

==== Fuzz Testing (various projects) ====

Fuzz testing or fuzzing is a software testing technique, often automated or semi-automated, that involves providing invalid, unexpected, or random data to the inputs of a computer program. The program is then monitored for exceptions such as crashes, or failing built-in code assertions or for finding potential memory leaks. Fuzzing is commonly used to test for security problems in software or computer systems.

* [[GSoC2014/Scheduler/CrossServicesScheduler|Implement a cross-services scheduler]]

==== OpenStack Monitoring and Telemetry (Ceilometer) ====

Ceilometer aims to deliver a unique point of contact for billing systems to acquire all counters they need to establish customer billing, across all current and future OpenStack components. The delivery of counters must be traceable and auditable. The counters must be easily extensible to support new projects, and agents doing data collections should be independent of the overall system.

For more details about Ceilometer project, check out the [[Ceilometer#OpenStack_Telemetry_.28Ceilometer.29|wiki]]

==== OpenStack Message Queuing Service (Marconi) ====

Openstack Message Queuing Service (Marconi) provides a distributed queue. The basic concept is simple:

* Create a queue
* Post messages
* Read them or claim them

==== OpenStack Common Libraries (Oslo) ====

The Oslo program produces a set of python libraries containing infrastructure code shared by OpenStack projects. The APIs provided by these libraries should be high quality, stable, consistent and generally useful.

Check out more details about Oslo project on the [https://wiki.openstack.org/wiki/oslo wiki]

* [[GSoC2014/Incubator/Plugin|Define a new layer/abstraction in Nova for plugging-in vCenter and ovirt (since they span multiple hosts)]] (WIP)

==== Benchmarking System (Rally) ====

OpenStack QA team mostly works on CI/CD that ensures that new patches don't break specific single node installation of OpenStack. On the other hand it's clear that such CI/CD is only an indication and does not cover all cases (e.g. if cloud works well on single node installation it doesn't mean that it will work good as well on 1k servers installation under high load).. Rally aims to fix this and help us to get answer on question "How OpenStack works at scale". To make it possible we are going to automate and unify all steps that are required for benchmarking OpenStack at scale: multi node OS deployment, verification, benchmarking & profiling.

[[File:Rally-Actions.png|500px|center]]

* Deploy is not yet another deployer of OpenStack it is just a plugable mechanism that allows to unify & simplify work with different deployers like: DevStack, Fuel, Anvil on hardware/VMs that you have.
* Verify - (work in progress) Use tempest to verify functionality of deployed openstack. In future Rally will support other OS verifiers.
* Benchmark - Smart combination of Framework, Load generation & Big repository of benchmarks.

Proposed ideas,

==== OpenStack Networking (Neutron) ====

Neutron is an OpenStack project to provide Networking-as-a-Service between interface devices (e.g., vNICs) managed by other Openstack services (e.g., Nova).

For full details about Neutron, check out the [https://wiki.openstack.org/wiki/Neutron wiki]

==== OpenStack Data Processing (Savanna) ====

Savanna aims to provide users with simple means to provision a Hadoop cluster by specifying several parameters like Hadoop version, cluster topology, nodes hardware details and a few more. The aim of this project is to enable users provision and management of Hadoop clusters on OpenStack.

Check out the [https://wiki.openstack.org/wiki/Savanna wiki] to learn more about Savanna

Proposed ideas,

* [[GSoC2014/DataProcessing/Plugin|Develop a new plugin for Savanna to extend savanna.plugins.provisioning:ProvisioningPluginBase class and implement all the required methods.]] (WIP)

==== OpenStack Infrastructure (infra) ====

The project infrastructure encompasses all of the systems that are used in the day to day operation of the OpenStack project as a whole. This includes development, testing, and collaboration tools. All of the software that we run is open source, and its configuration is public. The project still uses a number of systems that do not yet fall under this umbrella (notably, the main website), but we’re working to incorporate them so that people may just as easily contribute to those areas. All new services used by the project should begin as part of the infrastructure project to ensure easy collaboration from the start.

Proposed ideas,

* [[GSoC2014/ReplaceJenkins|Replace Jenkins with a more scalable solution based on the zuul-gearman protocol]]
