We have been humbled by the incredible interest, and rapid community growth of developers, operators, and partners. Our 0.1 release was focused on showing all the concepts of Istio in Kubernetes.</p><p>Today we are happy to announce the 0.2 release which improves stability and performance, allows for cluster wide deployment and automated injection of sidecars in Kubernetes, adds policy and authentication for TCP services, and enables expansion of the mesh to include services deployed in virtual machines. In addition, Istio can now run outside Kubernetes, leveraging Consul/Nomad or Eureka. Beyond core features, Istio is now ready for extensions to be written by third party companies and developers.</p></div><div class="read-more"> <a href="/v0.3/blog/istio-0.2-announcement.html"><span class="read-more-text">Read More</span></a></div><hr> <a href="/v0.3/blog/using-network-policy-in-concert-with-istio.html"><h4 id="/blog/0.1-using-network-policy" class="post-title">Using Network Policy in concert with Istio</h4></a><div class="post-date"> August 10, 2017</div><div class="post-author-company"></div><div class="post-excerpt"><p>The use of Network Policy to secure applications running on Kubernetes is a now a widely accepted industry best practice.

The idea behind canary deployment (or rollout) is to introduce a new version of a service by first testing it using a small percentage of user traffic, and then if all goes well, increase, possibly gradually in increments, the percentage while simultaneously phasing out the old version. If anything goes wrong along the way, we abort and rollback to the previous version. In its simplest form, the traffic sent to the canary version is a randomly selected percentage of requests, but in more sophisticated schemes it can be based on the region, user, or other properties of the request.</p><p>Depending on your level of expertise in this area, you may wonder why Istio’s support for canary deployment is even needed, given that platforms like Kubernetes already provide a way to do <a href="https://kubernetes.io/docs/concepts/workloads/controllers/deployment/#updating-a-deployment">version rollout</a> and <a href="https://kubernetes.io/docs/concepts/cluster-administration/manage-deployment/#canary-deployments">canary deployment</a>. Problem solved, right? Well, not exactly. Although doing a rollout this way works in simple cases, it’s very limited, especially in large scale cloud environments receiving lots of (and especially varying amounts of) traffic, where autoscaling is needed.</p></div><div class="read-more"> <a href="/v0.3/blog/canary-deployments-using-istio.html"><span class="read-more-text">Read More</span></a></div><hr><div class="pagination"> <span class="col-xs-6"></span><div class="next col-xs-6 text-right"> <a href="/v0.3/blog/page2/" >Older<span class="caret-right"></span></a></div></div><a class="rssLink" href="/v0.3/feed.xml"> <img title="RSS" alt="RSS" src="/v0.3/img/rss.gif" width="36" height="14"> </a></div></div></div><footer><div class="container"><div class="row"><div class="col-lg-2 col-md-2 col-sm-2"></div><div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 center-block"><ul><li><a class="header" href="/v0.3/docs/welcome">Docs</a></li><li><a href="/v0.3/docs/concepts">Concepts</a></li><li><a href="/v0.3/docs/setup">Setup</a></li><li><a href="/v0.3/docs/tasks">Tasks</a></li><li><a href="/v0.3/docs/guides">Guides</a></li><li><a href="/v0.3/docs/reference">Reference</a></li></ul></div><div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 center-block"><ul><li><a class="header" href="/v0.3/help">Help</a></li><li><a href="/v0.3/faq">FAQ</a></li><li><a href="/v0.3/glossary">Glossary</a></li><li><a href="/v0.3/troubleshooting">Troubleshooting</a></li><li><a href="/v0.3/bugs">Report Bugs</a></li><li><a href="https://github.com/istio/istio.github.io/issues/new?title=Issue with blog/index.html">Doc Bugs & Gaps</a></li><li><a href="https://github.com/istio/istio.github.io/edit/master/blog/index.html">Edit This Page</a></li></ul></div><div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 center-block"><ul><li> <a class="header" href="/v0.3/community">Community</a></li><li> <a href="https://groups.google.com/forum/#!forum/istio-users" target="_blank" rel="noopener">User</a> | <a href="https://groups.google.com/forum/#!forum/istio-dev" target="_blank" rel="noopener">Dev Mailing Lists</a></li><li><a href="https://twitter.com/IstioMesh" target="_blank" rel="noopener">Twitter</a></li><li><a href="https://stackoverflow.com/questions/tagged/istio" target="_blank" rel="noopener">Stack Overflow</a></li><li><a href="https://github.com/istio/community" target="_blank" rel="noopener">GitHub</a></li><li><a href="https://github.com/istio/community/blob/master/WORKING-GROUPS.md" target="_blank" rel="noopener">Working Groups</a></li></ul></div><div class="col-lg-1 col-md-1 col-sm-1"></div></div><div class="row"><p class="description small text-center"> Istio 0.3, Copyright © 2017 Istio Authors<br> Archived on 08-Dec-2017</p></div></div></footer><script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.15.0/jquery.validate.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.form/4.2.1/jquery.form.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-visible/1.2.0/jquery.visible.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/slick-carousel/1.6.0/slick.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/clipboard.js/1.7.1/clipboard.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <script src="/v0.3/js/common.min.js"></script> <script src="/v0.3/js/search.js"></script> <script src="/v0.3/js/prism.min.js"></script></body></html>
