Changelog 13th May 2021

Welcome to the Cloud 66 Changelog. These are the changes that have gone out this month:

Speeding up Rails Deployments by 25%

Rails

We've been working hard to speed up Rails deployments even more. While most of the changes are improvements behind the scenes, the most noticeable difference is that servers now have two stages while building: "ready" and optimized".

For more information check out our blog post.

Redis 6.2 Now Supported

Rails

We now support Redis v6.2 by default for new Redis installations! You can still specify an older version if you wish via your manifest. This Redis update brings performance, stability and security enhancements.

Application Updates

General

We rolled out two new features across all of our products to help with updating your applications: Application Updates and Maintenance Windows.

You can use Application Updates to apply or roll back features and updates on your applications when it suits you best. Read more about them on our blog.

Advanced AWS Firewall Configurations

General

New applications created on AWS will now have multiple associated security groups created and managed in AWS for that application. This is a change from the previous behavior where only a single security group would be created and managed per application.

The security groups are grouped by their role, so web servers will have web rules, and DB servers will have DB rules. Additionally, existing applications can be updated to use this new behavior via the their application updates. There is no change in the behavior of the UFW firewalls that already exist on each server.

This is the first piece of a series of new and exciting traffic control and management features we will be rolling out in the next 2 months. Stay tuned!

Multiple HAProxy Support

General

We're pleased to announce that we now support multiple HAProxy load balancers per application. This is very useful when you want to upgrade your HAProxy server; now you can simply fire up a newer HAProxy server, switch your DNS or Failover group to the newer one, and remove the older one.

Each HAProxy instance has a distinct configuration, so you can test changes to your settings without impacting your live application, and switch over when you're ready!
