| <h1>Discovery in the Cloud</h1> |
| |
| <div id="preamble"> |
| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p>Nodes discovery on a cloud platform is usually proven to be more |
| challenging because most virtual environments are subject to the |
| following limitations:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Multicast is disabled;</p> |
| </li> |
| <li> |
| <p>TCP addresses change every time a new image is started.</p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>Although you can use TCP-based discovery in the absence of the |
| Multicast, you still have to deal with constantly changing IP addresses. |
| This causes a serious inconvenience and makes configurations based on |
| static IPs virtually unusable in such environments.</p> |
| </div> |
| <div class="paragraph"> |
| <p>To mitigate the constantly changing IP addresses problem, Ignite supports a number of IP finders designed to work in the cloud:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Apache jclouds IP Finder</p> |
| </li> |
| <li> |
| <p>Amazon S3 IP Finder</p> |
| </li> |
| <li> |
| <p>Amazon ELB IP Finder</p> |

| <h2 id="apache-jclouds-ip-finder">Apache jclouds IP Finder</h2> |
| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p>To mitigate the constantly changing IP addresses problem, Ignite supports automatic node discovery by utilizing Apache jclouds multi-cloud toolkit via <code>TcpDiscoveryCloudIpFinder</code>. |
| For information about Apache jclouds please refer to <a href="https://jclouds.apache.org">jclouds.apache.org</a>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The IP finder forms nodes addresses by getting the private and public IP addresses of all virtual machines running on the cloud and adding a port number to them. |
| The port is the one that is set with either <code>TcpDiscoverySpi.setLocalPort(int)</code> or <code>TcpDiscoverySpi.DFLT_PORT</code>. |
| This way all the nodes can try to connect to any formed IP address and initiate automatic grid node discovery.</p> |
| </div> |
