Chef Server 12 Released [feedly]

Chef Server 12 Released
// Chef Blog

Ohai Chefs!

Today, after a thorough RC testing phase that included a great amount of feedback and contribution from the Chef community, we're pleased to announce the GA release of Chef Server 12. This release brings the previously premium features of Enterprise Chef, namely multi-tenancy and role-based access control, into Open Source Chef.

What's New

Chef Server 12 brings a host of improvements that will be welcomed by existing Open Source and Enterprise customers alike. Here are just a few:

All PostgreSQL, All the Time

Eighteen months ago, we released Chef 11 to the world. It was awesome, and it increased the scalability of the Chef Server to new levels. At the time, we had just rewritten the entire core of the API in Erlang and had migrated all of the data that the server stores from CouchDB to PostgreSQL. We soon followed up with Enterprise Chef 11, which brought this same scalability to our commercial customers.

Over the past year, we've been working tirelessly on removing the final bits of the CouchDB-backed Ruby API from the multi-tenancy features of the Chef Server, and we're pleased to announce that, with this release, we've completed that task.

Advancing the Chef Server Platform

With the removal of CouchDB and the consolidation of the Chef Server API into one codebase, we've been able to reduce the complexity and the footprint of the Chef Server platform. This starts with a 20% reduction in package size and a 25% reduction in the number of active services running on the Chef Server.

Building on top of this, we now have a fresh, consistent, and open-source codebase that will help us accelerate new feature development around the ways that you interact with your Chef Server. Some of our most-requested features like external authentication, external groups via LDAP, and templated organization policy can be built atop Erlang and PostgreSQL — a technology stack that we're heavily invested in at Chef and one that won't be going away anytime soon.

Search Improvements – Solr 4 Brings the Speed

Chef uses the Apache Solr search server to handle the search-based discovery for your Chef infrastructure. The version of Solr (1.4) that ships with the Chef 11 Servers was released in November 2009. In technology terms, that's ancient. Over the past 5 years, the Solr team has shipped some amazing features and improvements to their product, and we're pleased to announce that the Chef community will now get to experience those.

Since its inception, one of the most frequently requested improvements to Chef Server has been to reduce the amount of time that it takes for a saved object to become searchable. In Chef 11 and earlier, that latency was anywhere between one and sixty seconds. If you had a heavily loaded Chef Server, then it may take even longer while the asynchronous process sending your data to Solr was catching up to the request load. At the worst of times, Hosted Chef would experience search latencies longer than 10 minutes.

Solr 4 has allowed us to solve this problem. We've been running this version of Solr in Hosted Chef for a few months now, and the average search latency is just over one second.

Instant Access to Premium Features

For the first time ever, every user of Chef will have instant access to try out any of the premium features provided by Chef Software simply by running

chef-server-ctl install $premium-feature-name

Those premium features include:

  • Analytics Platform: Get visibility into your Chef servers, verify compliance and keep up with changes, all with the Chef analytics platform.
  • Management Console: Use the web-based management console to manage RBAC, edit and delete nodes, and reset private keys. Keep up to date with what's happening during chef client runs across an entire organization or on specific nodes.
  • Reporting: Capture and visualize what happens during the execution of chef-client runs across all of your Chef-managed infrastructure.
  • High Availability: Ensure that your Chef service is uninterrupted within your data center or AWS region, even if a Chef server fails.
  • Replication: Maintain a single worldview across multiple locations and ensure consistency across your network, no matter how many data centers or cloud availability zones you use in your enterprise.

All of these features are free for installs of fewer than 25 nodes, and come with a 30 day free trial for larger installs.

Chef Identity – Run Your Own Supermarket

Chef 12 now ships with Chef Identity included, allowing external applications like Supermarket and Chef Analytics to authenticate with Chef Server. Take a look at the blog post for Supermarket for instructions on setting this up.
