What is Advanced Auto Scaling?

    December 15, 2020

    While our standard Auto Scaling resources are typically more than enough in most cases, if you’re expecting a tsunami of traffic Nexcess Advanced Auto Scaling lets you add additional PHP workers for days, weeks, months, or however long you need it.

    No long-term commitments - just the scalability you need for as long as you need it.

    How Does Advanced Auto Scaling Work?

    The Advanced Auto Scaling feature is designed to allow your site to scale during planned or unplanned high-traffic events. It does this by moving the PHP workload into containers, allowing for unlimited horizontal scaling (added in batches of 10). 

    However, this type of scaling comes at the expense of increased average page load time, adding up to 1s to uncached page loads. It is recommended to only enable Advanced Auto Scaling when you are expecting or experiencing significant traffic volume on your web site.

    Advanced Auto Scale Pricing

    Enabling Advanced Auto Scaling costs $99 / month. This will shift the PHP workers from their infrastructure to a container.

    As you need more resources (to be able to handle more concurrent users), you can add additional containers with 10 PHP workers a piece for $50/day.

    To enable advanced auto scaling in the portal you will need to first disable cloud auto scaling by setting that toggle to be off.

    After cloud auto scaling has been set to be off. Now you can enable the advanced auto scaling in the portal.

    Now that advanced auto scaling has been enabled it will now show as being set in the portal.
