-<blockquote>
-<p>We are moving our Apache 2.0-licensed source code in Elasticsearch and Kibana to be dual licensed under Server Side Public License (SSPL) and the Elastic License, giving users the choice of which license to apply. This license change ensures our community and customers have free and open access to use, modify, redistribute, and collaborate on the code. It also protects our continued investment in developing products that we distribute for free and in the open by restricting cloud serv [...]
-</blockquote>
-<p>Also, they provide the <a href="https://www.elastic.co/pricing/faq/licensing">FAQ page</a> for more information about the impact for the users, developers, and vendors.</p>
-<p>In the perspective of Apache Software Foundation, SSPL has been confirmed as a Catalog X LICENSE(<a href="https://www.apache.org/legal/resolved.html#category-x),">https://www.apache.org/legal/resolved.html#category-x),</a>
-which means hard-dependency as a part of the core is not allowed.
-With that, we can&rsquo;t only focus on it anymore. We need to consider other storage options. Right now, we still have InfluxDB, TiDB, H2 server still in Apache 2.0 licensed.
-Right now, we still have InfluxDB, TiDB, H2 server as storage options still in Apache 2.0 licensed.</p>
-<p>As one optional plugin, we need to focus on the client driver license.
-Right now, we are only using ElasticSearch 7.5.0 and 6.3.2 drivers, which are both Apache 2.0 licensed. So, we are safe.
-For further upgrade, here is their announcement. They answer these typical cases in the FAQ page.</p>
+	<p>We posted <a href="/blog/2021-01-17-elastic-change-license/"><strong>Response to Elastic 2021 License Change</strong></a> blog 4 months ago. It doesn&rsquo;t have a big impact in
+short term, but because of the incompatibility between SSPL and Apache 2.0, we lost the chance of upgrading the storage server,
+which makes the community and our users concern. So, we have to keep looking for a new option as a replacement.</p>
+<p>There was an open source project, Open Distro for Elasticsearch, maintained by the AWS team. It is an Apache 2.0-licensed distribution of Elasticsearch enhanced with enterprise security, alerting, SQL, and more. After Elastic relicensed its projects, we talked with their team, and they have an agenda
+to take over the community leadship and keep maintaining the ElasticSearch, as it was licensed by Apache 2.0. So, they are good to fork and continue.</p>
+<p>On April 12th, 2021, AWS announced the new project, OpenSearch, driven by the community, which is initialized from people of AWS, Red Hat, SAP, Capital One, and Logz.io. Read this <a href="https://aws.amazon.com/cn/blogs/opensource/introducing-opensearch/">Introducing OpenSearch</a> blog for more detail.</p>
+<p>Once we had this news in public, we begin to plan the process of evaluating and testing OpenSearch as SkyWalking&rsquo;s storage option.
+Read our <a href="https://github.com/apache/skywalking/issues/6745">issue</a>.</p>
+<p><strong>Today, we are glad to ANNOUNCE, OpenSearch could replace ElastcSearch as the storage, and it is still licensed under Apache 2.0.</strong></p>
+<p>This has been merged in the main stream, you could find it in the dev doc already.</p>
+<h3 id="opensearch">OpenSearch</h3>
+<p>OpenSearch storage shares the same configurations as ElasticSearch 7.
+In order to activate ElasticSearch 7 as storage, set storage provider to <strong>elasticsearch7</strong>.
+Please download the <code>apache-skywalking-bin-es7.tar.gz</code> if you want to use OpenSearch as storage.</p>
+<p>SkyWalking community will keep our eyes on OpenSearch project, looks forward to their first GA release.</p>

-<blockquote>
-<p>I build a SaaS application using Elasticsearch as the backend, how does this affect me?</p>
-</blockquote>
-<p>This source code license change should not affect you - you can use our default distribution or develop applications on top of it for free, under the Elastic License. This source-available license does not contain any copyleft provisions and the default functionality is free of charge. For a specific example, you can see our response to a question around this at Magento.</p>
-<p><strong>Our users still could use, redistribute, sale the products/services, based on SkyWalking, even they are using self hosting Elastic Search unmodified server.</strong></p>
-<hr>
-<blockquote>
-<p>I&rsquo;m using Elasticsearch via APIs, how does this change affect me?</p>
-</blockquote>
-<p>This change does not affect how you use client libraries to access Elasticsearch. Our client libraries remain licensed under
-Apache 2.0, with the exception of our Java High Level Rest Client (Java HLRC).
-The Java HLRC has dependencies on the core of Elasticsearch, and as a result this client library will be licensed under the
-Elastic License. Over time, we will eliminate this dependency and move the Java HLRC to be licensed under Apache 2.0. Until
-that time, for the avoidance of doubt, we do not consider using the Java HLRC as a client library in development of an
-application or library used to access Elasticsearch to constitute a derivative work under the Elastic License, and this will not
-have any impact on how you license the source code of your application using this client library or how you distribute it.</p>
-<p><strong>The client driver license incompatible issue will exist, we can&rsquo;t upgrade the driver(s) until they release the Apache 2.0 licensed driver jars.</strong>
-<strong>But users are still safe to upgrade the drivers by themselves.</strong></p>
-<hr>
-<p>Apache SkyWalking will discuss the further actions <a href="https://github.com/apache/skywalking/issues/6219">here</a>. If you have any question, welcome to ask.
-In the later 2021, we will begin to invest the posibility of creating SkyWalking&rsquo;s observability database implementation.</p>
+<p>At last,  we have to add a NOTICE to the ElasticSearch storage doc, to warn the user, please choose it carefully.</p>
+<p><strong>NOTICE:</strong> Elastic announced through their blog that Elasticsearch will be moving over to a Server Side Public
+License (SSPL), which is incompatible with Apache License 2.0. This license change is effective from Elasticsearch
+version 7.11. So please choose the suitable ElasticSearch version according to your usage.</p>

+      <description>
+        
+        
+        &lt;p&gt;We posted &lt;a href=&#34;/blog/2021-01-17-elastic-change-license/&#34;&gt;&lt;strong&gt;Response to Elastic 2021 License Change&lt;/strong&gt;&lt;/a&gt; blog 4 months ago. It doesn&amp;rsquo;t have a big impact in
+short term, but because of the incompatibility between SSPL and Apache 2.0, we lost the chance of upgrading the storage server,
+which makes the community and our users concern. So, we have to keep looking for a new option as a replacement.&lt;/p&gt;
+&lt;p&gt;There was an open source project, Open Distro for Elasticsearch, maintained by the AWS team. It is an Apache 2.0-licensed distribution of Elasticsearch enhanced with enterprise security, alerting, SQL, and more. After Elastic relicensed its projects, we talked with their team, and they have an agenda
+to take over the community leadship and keep maintaining the ElasticSearch, as it was licensed by Apache 2.0. So, they are good to fork and continue.&lt;/p&gt;
+&lt;p&gt;On April 12th, 2021, AWS announced the new project, OpenSearch, driven by the community, which is initialized from people of AWS, Red Hat, SAP, Capital One, and Logz.io. Read this &lt;a href=&#34;https://aws.amazon.com/cn/blogs/opensource/introducing-opensearch/&#34;&gt;Introducing OpenSearch&lt;/a&gt; blog for more detail.&lt;/p&gt;
+&lt;p&gt;Once we had this news in public, we begin to plan the process of evaluating and testing OpenSearch as SkyWalking&amp;rsquo;s storage option.
+Read our &lt;a href=&#34;https://github.com/apache/skywalking/issues/6745&#34;&gt;issue&lt;/a&gt;.&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;Today, we are glad to ANNOUNCE, OpenSearch could replace ElastcSearch as the storage, and it is still licensed under Apache 2.0.&lt;/strong&gt;&lt;/p&gt;
+&lt;p&gt;This has been merged in the main stream, you could find it in the dev doc already.&lt;/p&gt;
+&lt;h3 id=&#34;opensearch&#34;&gt;OpenSearch&lt;/h3&gt;
+&lt;p&gt;OpenSearch storage shares the same configurations as ElasticSearch 7.
+In order to activate ElasticSearch 7 as storage, set storage provider to &lt;strong&gt;elasticsearch7&lt;/strong&gt;.
+Please download the &lt;code&gt;apache-skywalking-bin-es7.tar.gz&lt;/code&gt; if you want to use OpenSearch as storage.&lt;/p&gt;
+&lt;p&gt;SkyWalking community will keep our eyes on OpenSearch project, looks forward to their first GA release.&lt;/p&gt;
+&lt;hr&gt;
+&lt;p&gt;At last,  we have to add a NOTICE to the ElasticSearch storage doc, to warn the user, please choose it carefully.&lt;/p&gt;
+&lt;p&gt;&lt;strong&gt;NOTICE:&lt;/strong&gt; Elastic announced through their blog that Elasticsearch will be moving over to a Server Side Public
+License (SSPL), which is incompatible with Apache License 2.0. This license change is effective from Elasticsearch
+version 7.11. So please choose the suitable ElasticSearch version according to your usage.&lt;/p&gt;
