cPanel High Availability Roadmap

[cPanelDustin]

We have begun heavy research phases of High Availability for cPanel. We have a forecasted roadmap for HA and we will continue adding additional information to it as we flesh out the project further.

Amazing News!

Let's hope and pray that they won't dare to add more extra costs for features that should be available years ago.
Personally, any future price increase by cpanel, i will drop all the licenses i have with them and make a final goodbye.

thats great news! happy to be beta tester if needed @cPanelDustin

 

[kodeslogic]

That is very exciting news.

I'd like to ask what features you all might find useful or necessary when it comes to High Availability. What are things that would be valuable to you? I think for all of us working on this project we want to ensure that we're building something that is useful and valuable to everyone and the only way we can really make that happen is by finding out what you want and need.


Thanks!

For us the least useful feature is DNS load balancing. We already have a cPanel DNS-only cluster, so we have no need for that. It also seems a little funny that you put config guide at the end (although that's not what the text of the post says).

We'll look forward to this and test it, but in all honestly, I'm not sure how much sales traction we'll actually get. We offered HA in another product line we have (not web hosting related) and most clients were interested until they figured out they had 2X the server costs (dedicated or VPS). When they sat down and figured out what the mostly cost vs. the small amount of downtime that they typically had, it did not end up making a lot of sense to most customers.

The HA also added a fair amount of complexity in upgraded. Things like MySQL upgrades immediately come to mine. It's trivial (thank you cPanel) to to upgrade MySQL, but if you have a replicated database, that's going to get more complex.

I know my team is specifically working on SQL aspect of this, but since this is a collaborative effort between 4 teams, this is all valuable feedback thank you for taking the time to provide it.

looking forward for this feature as one of our upcoming project requires HA mandatory.

Yes, following this.... have been an advocate for over ten years, so this is very welcome.... should I start holding my breath yet?

Meanwhile, many service providers now offer "managed databases" (e.g. Digital Ocean, Vultr - by managed, I mean HA databases, geographically dispersed) - since most of the sites we manage are WordPress is that something your team is looking into ?

It is something we're looking at though we might not offer it right out of the gate. There are latency concerns that we want to ensure we address.

Good news folks!

We have updated the roadmap with more information about the direction we're heading. As always, feedback is welcome.

The roadmap is looking pretty good. Using K8 is a very good idea. It would help greatly in isolation of websites/accounts, resource management and limits and security.

Will the db deployments also be per-site? The web pods are per-site basis. If the db pods are also per-site basis and they are HA (like some operators out there), that would help a lot in isolation of sites.

Also NFS is a major pain point. If you could select a good K8 operator (rook-ceph etc) to provide it from within cPanel itself, that would help greatly. Otherwise operating an NFS would be problematic for a majority.
