Open Source Scalr 5.10 is Out!

January 4, 2016 Ron Harnik

We’re excited to announce the release of Open Source SCALR 5.10!

Open Source Scalr is the free, Open Source, fully featured edition of the SCALR Enterprise Cloud Management Platform. It’s a snapshot of an earlier release of the Enterprise edition, so any feature released in SEE will eventually make its way to SCE.

SCE 5.10 brings improved performance and stability, and a breadth of new features, many of which were already covered on our Product Blog.


SCE 5.10 is packed with new features, the most we’ve ever had in a single release of SCE.

Every new feature that’s introduced to SCALR is based on repeatable use-cases from our customers and feedback from the community, so as always, we encourage you to get in touch with us and send us your feedback. The SCALR Cloud Management Platform continues to evolve and get better thanks to the amazing community of SCALR users, across the Enterprise, Hosted and Community editions.


So what’s new with 5.10?

You can check the full changelog here for a list of all changes, bug fixes, improvements and new features, but here are some of the highlights.


Support for Microsoft Azure

Perhaps the most notable addition to SCE 5.10 is the added support for the Microsoft Azure public cloud platform. You can now leverage SCALR to automate infrastructure provisioning and enforce governance policies on Microsoft Azure.


 Scalr Community Edition 5.10 - Microsoft Azure


From the Azure blog:

“Scalr on Azure will be available immediately in 19 regions (soon to be 24), supporting more regions than AWS and GCE, combined. This broad global coverage that Azure offers will enable you to run your application closer to your end-customers or employees while offering simple management of cloud-native infrastructure using Scalr. You can even combine deployed Virtual Machines with a wide range of Azure PaaS services, like Azure Web Apps, Mobile Apps, or Logic Apps.”


With Azure joining AWS and GCE, SCALR now supports all major public clouds. Moving forward, we will work to deepen our support for each cloud, allowing you to enjoy unified cloud management while leveraging each platform’s strengths. Today, you can already enforce governance policies, control storage and networking settings and use Cost Analytics on Azure.

Read-Only ACLs

ACLs are lists of permissions you can use to enforce Role Based Access Control on your entire cloud infrastructure. Once a team has been granted access to an Environment, the relevant ACL will determine the level of access the team has to features in that Environment. Up until now, the permission controls were “Full Access”, “No Access” and in some cases “Limited”. It was impossible to allow a team to view information without giving them the ability to modify it.

The new “Read-Only” ACL permission setting allows you to do just that, grant the ability to view but not to edit.

Resize Suspended EC2 instances

In previous releases of SCE, changing the type of an EC2 instance meant changing the type for all instances of the Role, and the change would only affect newly provisioned instances. With 5.10, you can suspend individual instances, change their type (i.e. from m3.medium to m3.large), and resume the resized instance.

Enhanced Management for Roles and Images at The Account Scope

Creating Role and Images in SCALR is a great way to create reusable building blocks and share efforts across business units in a large organization. Up until now, you could only create and manage Roles and Images independently for each environment.

With SCE 5.10, you can manage Roles and Images at the Account Scope.

Now, Roles and Images follow the same pattern as other features that utilize SCALR’s concept of Scopes. Any Role or Image that has been created at the Account Scope will be available for consumption by every Environment in that Account.

In addition to the introduction of Roles and Images to the Account Scope, SCE 5.10 brings new management capabilities. You can now restrict the availability of a Role to specific Environments. When you create a Role at the Account Scope, use the new “Permissions” tab to choose which Environments can consume that Role.

You can now easily search for Farms and servers at the Account and Environment Scopes. Use the new search component to find Farms or individual servers from any screen in your Account and Environment, and get a concise summary about the relevant resource.
