Subject [DISCUSS] Accept Stratos as an Apache Incubation Project
Date Tue, 11 Jun 2013 09:10:18 GMT
It's with great pleasure that I invite the IPMC to review a new
proposal [1] for the Apache Incubator. Please let us know if you have
any questions or comments - as you will see there are plenty of people
on the initial commit list ready and willing to answer your questions.

I copy the full text of the proposal for your convenience:

= Stratos - A PaaS Framework =
== Abstract ==
Stratos will be a polyglot
[[http://www.gartner.com/it-glossary/platform-as-a-service-paas|PaaS]]
framework, providing developers a cloud-based environment for
developing, testing, and running scalable applications, and IT
providers high utilization rates, automated resource management, and
platform-wide insight including monitoring and billing.
== Proposal ==
The Stratos PaaS framework will encompass four layers:
 1. An [[http://www.gartner.com/it-glossary/infrastructure-as-a-service-iaas/|IaaS]]-agnostic
layer that can interface with a wide variety of IaaS systems to
provide elastic resources, and for multiple IaaS infrastructures to be
automated at one time (hybrid clouds.)
 2. A PaaS Controller with a cloud controller that automates and
monitors IaaS runtime interactions, distributes artifacts to the
underlying runtimes, deploys workloads, directs runtime traffic to the
right runtimes using a tenant-aware elastic load balancer, and
provides a portal for monitoring and provisioning of tenants on the
system.
 3. Foundational Services including security, logging, messaging,
registry, storage (relational, file, and noSQL), task management, and
billing.  Foundational services will be loosely-coupled to allow
swapping in alternate foundational services.
 4. A Cartridge Architecture allowing frameworks, servers, and other
runtimes to participate in the advantages of the system.  The
Cartridge Architecture must support multi-tenant workloads, and
provide for various levels of tenant isolation and policy-based
control over provisioning.

Together these layers offer a foundational layer upon which
applications and middleware frameworks can be deployed to speed
time-to-market and simplify the development of scalable applications,
as well as provide a high level of resource sharing and centralized
management that can deliver lowest resource, infrastructure, and
management costs.
== Background ==
The Stratos Project has been under development[a] at http://wso2.org
under the Apache 2.0 license and the Apache Way governance model since
2010.  It initially was focussed on providing PaaS benefits to the
users of WSO2 Carbon middleware platform.  In version 2.0, to be
released in summer 2013, extensive work has been done to clearly
separate out the PaaS framework from the products (cartridges) that
run on top of it.  Stratos now has the ability to run arbitrary
workloads, including Java, PHP, MySQL, Jetty, Tomcat, and many more.
== Rationale ==
PaaS is in demand by enterprises and organizations of all sizes.  The
drive towards instance provisioning, high resource utilization and
thus low cost, combined with a wide platform of general-purpose
services to build on, PaaS has the opportunity to accelerate the
development cycle and innovation index of a new class of applications,
services, and business models.

PaaS offerings are widely diversified but largely associated with
powerful corporate interests.  With the commencement of the Stratos
project at Apache, vendors and users will have a neutral community
free from corporate governance restrictions, with which to collaborate
and accelerate the development of a platform that provides wide
benefits across the industry.  As a flexible framework, we expect a
wide variety of platforms to leverage the technology to fill specific
niches and needs.
== Current Status ==
Stratos has been in development since 2010 at WSO2, under the Apache
License and under the Apache Way.  Contribution to Apache, from which
many of the core components are sourced, should be very
straightforward.
== Meritocracy ==
The contributors have a longstanding commitment and practice of
meritocracy in their personal and professional capacities. Many of the
committers on the existing project are already Apache Committers.
== Community ==
The committers recognize the need to support more significant
contributions from a broad swath of the industry and community.
Apache is the obvious choice for a project that already embodies
Apache values and is driven by developers who are committers on many
other Apache projects.

Stratos has appeal, and should attract community members, from among a
number of constituencies:
 * Private PaaS deployment within an enterprise to benefit enterprise
application deployment.
 * PaaS providers wishing to leverage a PaaS toolkit to build a PaaS
customized to their particular vertical industry, ecosystem, or
internal development processes.
 * SaaS providers wishing to build upon a widely-deployed and
supported elastic, multi-tenant platform.
 * ISPs wishing to offer hosted application services with higher
resource utilization capabilities than provided by IaaS layers.
 * IaaS vendors wishing to provide higher-level PaaS services to customers.
 * Vendors wishing to support Stratos on or under their projects and
products.  Vendors of higher level runtimes will contribute Cartridges
enabling those runtimes to participate in the Stratos-sphere.  Vendors
of underlying IaaS infrastructure will contribute adapters to ensure
their IaaS is fully operational for Stratos.
== Core Developers ==
All core developers are currently employed by WSO2. This is a very
important project for our company and is a core part of our business.
Whilst we have sought to engage a broader community through the
meritocratic model this has, until now, manifested itself through our
teams contributions to other projects used within Stratos, including
Apache Axis2, Apache Synapse, Apache Axiom & Apache Web Services. With
this move to the ASF we are signalling that the door is wide open for
external contributors.

== Known Risks ==
Stratos has largely been developed by sponsored developers employed at
a single organization - WSO2.  Seeking a broader community of
contributors is a top goal of contributing Stratos to Apache.
WSO2 plans to continue to offer services and commercial support
packages for Stratos, so there is a financial incentive to broaden
Stratos’ appeal.  This may provide the misinterpretation that Stratos
remains merely a WSO2 technology.  However, WSO2’s main business
strategy is to build and support higher level PaaS offerings
(including the WSO2 middleware stack) on top of a common PaaS
framework, as provided by Stratos.  This includes a WSO2 StratosLive
option which is a public PaaS based on WSO2 Stratos.
Compatibility with a wide variety of IaaS and other ecosystem
partners, and setting, conforming to or advancing a set of open
standards, will be necessary to ensure Stratos gains traction as a
uniting force in the industry.
PaaS is on the uphill swing of the hype curve at present.  For the
project to succeed it needs to focus on concrete long-term value to
those using or deploying the PaaS.
The project was previously named and trademarked as “WSO2 Stratos”,
but the contributors do not believe that this name has built a strong
industry brand, and the transition to the name “Apache Stratos” should
not induce significant confusion. WSO2 has no intention of continuing
to use this mark. We will also work with VP Brand Management to ensure
the Stratos mark is secure within the ASF.

== External Dependencies ==
All components and dependent components are licensed under the Apache
or compatible license, and many of the components reside at the ASF.
== Cryptography ==
The software does not implement any cryptographic algorithms. However,
to perform secured messaging and data movement and SSL communications,
the software depends upon third party security libraries. These
external libraries depend in turn on Java Security and Bounce Castle
libraries. Apache Cryptographic steps will be followed to register the
use of these libraries.
