<p>Apache Stratos is the only open community controlled open-source PaaS
offering. The Apache community is based on participation and meritocracy
instead of financial sponsorship. In the Apache community meritocratic process,
known as "The Apache Way," more than 400 individual members and 3,500
committers successfully collaborate to develop freely-available,
enterprise-grade software, benefiting millions of users worldwide. The Apache
Software Foundation was established in 1999; the all-volunteer Foundation
oversees more than 170 leading open source projects, including Apache HTTP
Server, which is the world's most popular Web server software, Tomcat server,
Cassandra, CouchDB, CloudStack, and many others.</p>

+<p>Figure 1 illustrtates how Apache Stratos' core components (Cloud
Controller, CEP, Auto Scaler, and Stratos Manager, which include Artifact
Distribution Coordinator and Rest API) integrate with the IaaS layer,
foundation services, and dynamic services, which include cartridges.</p>
+<h2>Why is this architecture so important?</h2>
+<p><strong>The cartridge model</strong> provides run-time extendability to any
type of cartridge, such as language cartridge, framework cartridge, and data
cartridge without having to bind with any specific operating systems. This
enables the PaaS to be of a polyglot nature, which is important, so it would
not have limitations like with many other PaaS offerings.</p>
+<p>Another key advantage of the Apache Stratos cartridge model is that it
enables to bring even legacy containers and applications into the cloud with
ease. Therefore, with Apache Stratos, you can cloud enable both existing IT
assets as well as future IT assets that you plan to use or are yet to
acquire.</p>

+<p>Another important architecture design in Apache Stratos is unified
communication among all components that use the message bus and real-time event
bus. It provides a unified interface to integrate with any third-party system
or extends to work with existing systems. Moreover, it has been carefully
designed to meet heavy traffic via the real-time event bus (via thrift
protocol) and uses AMQP for messages that need reliable delivery.</p>
+<p>A key extensibility aspect of Apache Stratos is its ability to plugin any
IaaS due to the use of apache jclouds API. This provides more freedom to choose
your own IaaS vendor, and allows to extend multiple IaaS integrations, which
are important in features like cloud bursting, etc.</p>
