Cloud transformation is a significant investment -- is it future proof?
Will my cloud-native app work on (OpenStack based) cloud X?
OpenStack seems so chaotic ... Is it really enterprise-ready?
Can I do cloud-bursting for my app from my private cloud to public?
Can I use tool Y on both my private cloud X and public cloud Z?

InterOp Guidelines
RefStack Client
RefStack Server
Interop Working Group
-
OpenStack Foundation Board commissioned working group to formalize an interoperability guideline consisting of:
- Capabilities that must be present as part of the product API. These capabilities are measured by set of must-pass tests.
- Designated Sections that are the upstream OpenStack code that must be present in the product.
- Complying with this guideline is required to qualify for the OpenStack Powered trademark for public & private clouds, and distributions.
Interop Working Group was formerly known as DefCore
RefStack
There are two parts in the RefStack project:
-
RefStack Client
- RefStack Client is a command line tool that runs test tools (Tempest), summarizes results, and communicates with the refstack api. Vendors can use refstack client to run the tests themselves in a controlled and repeatable way.
-
RefStack Server
- RefStack API is a central repository for the collection of results and is currently hosted at https://refstack.openstack.org/ . It can also be hosted locally within any organization's infrastructure.
- RefStack UI is a web interface for interacting with data collected with the api and client ( https://refstack.openstack.org/ ).
RefStack Client
- RefStack provides a one-step setup command (setup_env) which takes care of installation of all dependencies including Tempest. https://github.com/openstack/refstack-client/blob/master/README.rst
-
Testing
- Currently based on Tempest Test Suite.
- By default, RefStack will install a specific Tempest SHA which was used by the DefCore committee to define the must-pass tests. RefStack also provides options allowing users to override the default Tempest version.
- Once refstack-client is installed, Tempest is located at <refstack-client home directory>/.tempest.
-
Uploading results
- JSON format result that complying with the RefStack result schema
- Data can be uploaded anonymously or with signature
RefStack Website
-
Users can view and manage test results.
- Allows users to compare their results to guidelines.

Interpreting Test Results
On the results report page for each test run, a user can check result against multiple guideline versions and target programs.
Can view all passed tests by clicking on the count.
Compliance with the selected guideline and target program is denoted by the percentage and the colored YES/NO.
- OpenStack Powered Storage
- OpenStack Powered Compute
- OpenStack Powered Platform
Three Powered Trademarks
- New major programs?
- Additions to existing programs?
New Powered Trademarks?
- Allowing new major programs
- Adding program extensions
- Can specify dependencies
- Mostly stays the same
- Capabilities with tests
- Designated sections with code
Interop Guidelines v2.0
- Encouraging stakeholders to build their own guidelines.
- Interop Working Group will maintain control of official trademark eligible guidelines.
- Goal is project owners should define minimums for interop.
Community Driven Guidelines
- NFV
Proposed Platforms for 2018
- DNS (Designate)
- Orchestration (Heat)
- Secrets (Barbican)
- Container Orchestration (Magnum)
- Database (Trove)
- Big Data (Sahara)
Proposed Extensions for 2018
RefStack Future plans
- Accept any test result (using Tempest Test Suite or not) that adheres to RefStack result schema.
- Facilitate checking result against customized guidelines
Community defined guidelines

Allows to finally get an answer to the initial question: Does app A or tool B work on OpenStack Cloud X?
Custom Profiles
1. Understand your application/tool
- API calls
- Expected behavior
2. Create tests
- reuse existing tempest tests
- fill gaps (tempest and beyond)
3. Create test list (custom profile)
- schema v2 will help ...
4. Upload to refstack server
Taxanomy of custom profiles
1. Private custom profiles:
Answering question privately
2. Sharing of custom profiles:
E.g. User to service provider ...
3. "Official" special profiles (?):
Public testability
Curation process?
4. Trademark guidelines
