+Designate Contributors
+======================
+
+Summary
+-------
+
+The OpenStack community is seeking contributors and maintainers for
+`Designate`_, an OpenStack project that provides self-service
+management of DNS Zones and Recordsets by OpenStack end users.
+
+Contributors will help find and fix bugs, develop new features, and
+help maintain the quality of the project, including cross-project
+initiatives.  Designate is quite stable, with any new features
+requiring long term planning, design, and phased implementation.
+
+Business Case
+-------------
+
+Sponsorship of contributors to Designate presents a great opportunity
+for an organization to gain in-house familiarity with large scale,
+self-service DNS as a service as an alternative to complex ticket
+based workflows for DNS updates.
+
+Additionally, organizations with in-house DNS expertise can bring it
+to bear on the challenges of the upstream project and thereby gain
+exposure to, and establish a reputation with, the OpenStack
+development community and the OpenStack operator community, as well as
+other organizations who distribute or use OpenStack downstream.
+
+And of course contributors to the project have a seat at the table as
+decisions are made about future Designate feature development,
+priorities, and the like.
+
+Designate welcomes everyone, from someone starting in the community to
+senior contributors who want new, interesting problems to
+tackle. Contributors will get to work on a project that will be a
+central part of any OpenStack deployment and work on a project that
+needs to scale from a small single node install to a system
+controlling DNS servers worldwide.
+
+Technical Details
+-----------------
+
+DNS is of course fundamental in gracefully directing users and
+applications to services.  Designate is a service that manages DNS Zones
+and Recordsets and the provides end users self-service management of
+these.  Designate is vital for any network or web-based application in
+a self-service infrastructure cloud.
+
+Flexibility
+~~~~~~~~~~~
+
+Designate allows the flexibility to replace underlying hardware while
+presenting consumers with a consistent endpoint with an abstraction
+layer over a wide range of drivers for various `DNS servers`_ and
+providers.  This allows deployers to integrate Designate into
+pre-existing DNS infrastructures.
+
+Self-Service
+~~~~~~~~~~~~
+
+Self-serviceability is a core tenet of OpenStack `technical
+vision`_. Designate helps OpenStack clouds adhere to that principle by
+exposing DNS functionality directly to end-users. Designate allows
+cloud operators to delegate the control of DNS zones to end users, to
+avoid complex ticket based workflows for DNS updates.
+
+
+User Experience
+---------------
+
+When end users are building applications in a cloud native way,
+relying on external tooling to provision DNS entries adds
+complexity. With the advancement of IPv6, services required to have
+DNS entries, to avoid application user confusion.
+
+Designate adds an important part of the value add for cloud
+infrastructure, and ensures that OpenStack has feature parity with
+other cloud providers.
+
+
+Integrations
+------------
+
+Designate integrates with many other tools to allow for zero touch
+management of DNS Zones and Records. The integration with neutron
+allows admins to have PTR records (for reverse DNS lookups) managed
+for Floating IP ranges, without giving direct privileged access to the
+reverse zone to users.
+
+Tools like `letsencrypt certbot`_ allow for auto provisioning of SSL
+certs using DNS-01 validation, while tools like `Heat`_, `Terraform`_
+and `Ansible`_ allow for the provisioning of DNS Zones and Records to
+be integrated into pre-existing workflows for applications.
+
+Kubernetes `external-dns`_ support adds simple annotation based DNS
+management for applications running in kubernetes clusters with load
+balancers or ingress support.
+
+Consistency
+~~~~~~~~~~~
+
+The OpenStack community continues to evolve, and this evolution
+requires large cross-project initiatives. Furthermore, users and
+operators expect consistency across the OpenStack platform. Examples
+from recent history include OpenStack-wide support for `Python 3`_ and
+easing operator pain by moving `policy configuration`_ into
+code. Ensuring Designate stays up-to-date with these initiatives is
+imperative in reducing operational costs, complexity, and user
+frustration.
