+Step 1: Read http://www.python.org/dev/peps/pep-0008/
+Step 2: Read http://www.python.org/dev/peps/pep-0008/ again
+Step 3: Read on
+
+Imports
+-------
+- thou shalt not import objects, only modules
+- thou shalt not import more than one module per line
+- thou shalt not make relative imports
+- thou shalt "from nova import vendor" before importing third party code
+- thou shalt organize your imports according to the following template
+
+::
+  # vim: tabstop=4 shiftwidth=4 softtabstop=4
+  {{stdlib imports in human alphabetical order}}
+  \n
+  from nova import vendor
+  {{vendor imports in human alphabetical order}}
+  \n
+  {{nova imports in human alphabetical order}}
+  \n
+  \n
+  {{begin your code}}
+
+
+General
+-------
+- thou shalt put two newlines twixt toplevel code (funcs, classes, etc)
+- thou shalt put one newline twixt methods in classes and anywhere else
+- thou shalt not write "except:", use "except Exception:" at the very least
+- thou shalt include your name with TODOs as in "TODO(termie)"
+- thou shalt not name anything the same name as a builtin or reserved word
+- thou shalt not violate causality in our time cone, or else
+
+
+Human Alphabetical Order Examples

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+nova System Architecture
+========================
+
+Nova is built on a shared-nothing, messaging-based architecture. All of the major nova components can be run on multiple servers. This means that most component to component communication must go via message queue. In order to avoid blocking each component while waiting for a response, we use deferred objects, with a callback that gets triggered when a response is received.
+
+In order to achieve shared-nothing with multiple copies of the same component (especially when the component is an API server that needs to reply with state information in a timely fashion), we need to keep all of our system state in a distributed data system. Updates to system state are written into this system, using atomic transactions when necessary. Requests for state are read out of this system. In limited cases, these read calls are memoized within controllers for short periods of time. (Such a limited case would be, for instance, the current list of system users.)
+
+

+Auth Documentation
+==================    
+
+Nova provides RBAC (Role-based access control) of the AWS-type APIs. We define the following roles:
+
+Roles-Based Access Control of AWS-style APIs using SAML Assertions
+“Achieving FIPS 199 Moderate certification of a hybrid cloud environment using CloudAudit and declarative C.I.A. classifications”
+
+Introduction
+--------------
+
+We will investigate one method for integrating an AWS-style API with US eAuthentication-compatible federated authentication systems, to achieve access controls and limits based on traditional operational roles.
+Additionally, we will look at how combining this approach, with an implementation of the CloudAudit APIs, will allow us to achieve a certification under FIPS 199 Moderate classification for a hybrid cloud environment.
+
+Relationship of US eAuth to RBAC
+--------------------------------
+
+Typical implementations of US eAuth authentication systems are structured as follows::
+
+  [ MS Active Directory or other federated LDAP user store ]
+  	--> backends to…
+  [ SUN Identity Manager or other SAML Policy Controller ]
+  	--> maps URLs to groups…
+  [ Apache Policy Agent in front of eAuth-secured Web Application ]
+       
+In more ideal implementations, the remainder of the application-specific account information is stored either in extended schema on the LDAP server itself, via the use of a translucent LDAP proxy, or in an independent datastore keyed off of the UID provided via SAML assertion.
+
+Basic AWS API call structure
+----------------------------
+
+AWS API calls are traditionally secured via Access and Secret Keys, which are used to sign API calls, along with traditional timestamps to prevent replay attacks. The APIs can be logically grouped into sets that align with five typical roles:  
+
+*	System User
+*	System Administrator
+*	Network Administrator
+*	Project Manager
+*	Cloud Administrator
+*	(IT-Sec?)         
+
+There is an additional, conceptual end-user that may or may not have API access:             
+
+*	(EXTERNAL) End-user / Third-party User    
+
+Basic operations are available to any System User:
+
+*	Launch Instance
+*	Terminate Instance (their own)
+*	Create keypair
+*	Delete keypair
+*	Create, Upload, Delete: Buckets and Keys (Object Store) – their own
+*	Create, Attach, Delete Volume (Block Store) – their own
+
+System Administrators:
+
+*	Register/Unregister Machine Image (project-wide)
+*	Change Machine Image properties (public / private)
+*	Request / Review CloudAudit Scans
+
+Network Administrator:
+
+*	Change Firewall Rules, define Security Groups
+*	Allocate, Associate, Deassociate Public IP addresses
+
+Project Manager:
+
+*	Launch and Terminate Instances (project-wide)
+*	CRUD of Object and Block store (project-wide)
+
+Cloud Administrator:
+
+*	Register / Unregister Kernel and Ramdisk Images
+*	Register / Unregister Machine Image (any)
+
+Enhancements
+------------
+
+*	SAML Token passing 
+*	REST interfaces
+*	SOAP interfaces
+
+Wrapping the SAML token into the API calls.
+Then store the UID (fetched via backchannel) into the instance metadata, providing end-to-end auditability of ownership and responsibility, without PII.
+
+CloudAudit APIs
+---------------
+
+*	Request formats
+*	Response formats
+*	Stateless asynchronous queries
+
+CloudAudit queries may spawn long-running processes (similar to launching instances, etc.) They need to return a ReservationId in the same fashion, which can be returned in further queries for updates.
+RBAC of CloudAudit API calls is critical, since detailed system information is a system vulnerability.
+
+Type declarations
+---------------------
+*	Data declarations – Volumes and Objects
+*	System declarations – Instances
+
+Existing API calls to launch instances specific a single, combined “type” flag. We propose to extend this with three additional type declarations, mapping to the “Confidentiality, Integrity, Availability” classifications of FIPS 199. An example API call would look like::
+
+  RunInstances type=m1.large number=1 secgroup=default key=mykey confidentiality=low integrity=low availability=low
+
+These additional parameters would also apply to creation of block storage volumes (along with the existing parameter of ‘size’), and creation of object storage ‘buckets’. (C.I.A. classifications on a bucket would be inherited by the keys within this bucket.)
+
+Request Brokering
+-----------------
+
+ *	Cloud Interop
+ *	IMF Registration / PubSub
+ *	Digital C&A
+
+Establishing declarative semantics for individual API calls will allow the cloud environment to seamlessly proxy these API calls to external, third-party vendors – when the requested CIA levels match.
+
+See related work within the Infrastructure 2.0 working group for more information on how the IMF Metadata specification could be utilized to manage registration of these vendors and their C&A credentials.
+
+Dirty Cloud – Hybrid Data Centers
+---------------------------------
+
+*	CloudAudit bridge interfaces
+*	Anything in the ARP table
+
+A hybrid cloud environment provides dedicated, potentially co-located physical hardware with a network interconnect to the project or users’ cloud virtual network. 
+
+This interconnect is typically a bridged VPN connection. Any machines that can be bridged into a hybrid environment in this fashion (at Layer 2) must implement a minimum version of the CloudAudit spec, such that they can be queried to provide a complete picture of the IT-sec runtime environment.
+
+Network discovery protocols (ARP, CDP) can be applied in this case, and existing protocols (SNMP location data, DNS LOC records) overloaded to provide CloudAudit information.
+
+The Details
+-----------
+
+ *	Preliminary Roles Definitions
+ *	Categorization of available API calls
+ *	SAML assertion vocabulary
+
+System limits
+-------------
+
+The following limits need to be defined and enforced:  
+
+*	Total number of instances allowed (user / project)
+*	Total number of instances, per instance type (user / project)
+*	Total number of volumes (user / project)
+*	Maximum size of volume
+*	Cumulative size of all volumes
+*	Total use of object storage (GB)
+*	Total number of Public IPs
+
+
+Further Challenges
+------------------
+ *	Prioritization of users / jobs in shared computing environments
+ *	Incident response planning
+ *	Limit launch of instances to specific security groups based on AMI
+ *	Store AMIs in LDAP for added property control
+
