+<div class="sectionbody">
+<div class="paragraph">
+<p>Apache Karaf is a modern and polymorphic container.</p>
+</div>
+<div class="paragraph">
+<p>Karaf can be used standalone as a container, supporting a wide range of applications and technologies.
+It also supports the "run anywhere" (on any machine with Java, cloud, docker images, &#8230;&#8203;) using the embedded mode.</p>
+</div>
+<div class="paragraph">
+<p>It&#8217;s a lightweight, powerful, and enterprise ready platform.</p>
+</div>
+<div class="paragraph">
+<p>With this flexibility, Karaf is the perfect solution for microservices, systems integration, big data, and much more.</p>
+</div>
+<div class="paragraph">
+<p>Apache Karaf is powered by OSGi (but you don&#8217;t need to know what OSGi is to use Karaf).</p>
+</div>
+<div class="paragraph">
+<p>Apache Karaf uses either the Apache Felix or Eclipse Equinox OSGi frameworks, providing additional features on top of the framework.</p>
+</div>
+<div class="paragraph">
+<p>Apache Karaf can be scaled from a very lightweight container to a fully featured enterprise service: it&#8217;s a very flexible and extensible container, covering all the major needs.</p>
+</div>
+<div class="paragraph">
+<p>Here is a short list of provided features:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p><strong>Hot deployment</strong>: simply drop a file in the <code>deploy</code> directory, Apache Karaf will detect the type of the file and
+try to deploy it.</p>
+</li>
+<li>
+<p><strong>Complete Console</strong>: Apache Karaf provides a complete Unix-like console where you can completely manage the container.</p>
+</li>
+<li>
+<p><strong>Dynamic Configuration</strong>: Apache Karaf provides a set of commands focused on managing its own configuration.
+All configuration files are centralized in the <code>etc</code> folder. Any change in a configuration file is noticed and reloaded.</p>
+</li>
+<li>
+<p><strong>Advanced Logging System</strong>: Apache Karaf supports all the popular logging frameworks (slf4j, log4j, etc). Whichever
+logging framework you use, Apache Karaf centralizes the configuration in one file.</p>
+</li>
+<li>
+<p><strong>Provisioning</strong>: Apache Karaf supports a large set of URLs where you can install your applications (Maven repository, HTTP,
+file, etc). It also provides the concept of "Karaf Features" which is a way to describe your application.</p>
+</li>
+<li>
+<p><strong>Management</strong>: Apache Karaf is an enterprise-ready container, providing many management indicators and operations
+via JMX.</p>
+</li>
+<li>
+<p><strong>Remote</strong>: Apache Karaf embeds an SSHd server allowing you to use the console remotely. The management layer is also
+accessible remotely.</p>
+</li>
+<li>
+<p><strong>Security</strong>: Apache Karaf provides a complete security framework (based on JAAS), and provides a RBAC (Role-Based Access
+Control) mechanism for console and JMX access.</p>
+</li>
+<li>
+<p><strong>Instances</strong>: multiple instances of Apache Karaf can be managed directly from a main instance (root).</p>
+</li>
+<li>
+<p><strong>OSGi frameworks</strong>: Apache Karaf is not tightly coupled to one OSGi framework. By default, Apache Karaf runs with the Apache Felix
+Framework, but you can easily switch to Equinox (just change one property in a configuration file).</p>
+</li>
