Tell me about the stack

gavin

Hi,

I want to know about the stack of Enhance. I'll be testing it next week. I am really excited to try it now but stuck due to work commitments. So any nice soul care to tell me about the inner workings? I know it uses docker. Does it make container for each service like apache, php-fpm, mysql, wp site? or the containers shared in some form of multi-tenancy. How many containers, for what and how much resource consumption? Trying to get the ballpark idea of the whole platform before I try.

Thank you!

The role services are implemented as individual docker containers - for example the web server (Apache, LiteSpeed, OLS), Dovecot IMAP, Postfix, rspamd, etc. These containers are shared between the websites provisioned to hat server.

Website applications (currently PHP + any cron jobs, SSH sessions, etc) use Enhance's own containerisation engine using kernel namespaces and cgroups. These are individual per-website containers which ensures each website is isolated even within a single customer subscription.

Any overhead from the containerisation is negligible.

Thanks Adam! It feels like the much the needed revolution in the control panel space. Keep it up! The space is stuck with obsolete stuff with poor security. I am surprised that you went with own containerisation as I understand even docker uses cgroups with namespaces like most container technologies.

Adam

Docker struggles with very large numbers of containers, especially if they all need to start at once (for example after a reboot). Also there are places where we need more finely grained control of the environment, for example during PHP version changes.

Adam Hello Adam, as you know we plan on having lot of customers (bizz card websites) on a server, could you tell me a bit more about what is a very large number of containers. We run now approximately 250 sites on a server. We plan around 500 per server.

Adam

We test in CI with 4000 PHP containers. 250-500 is very reasonable and lots of customers run similar numbers.

Adam thanks for the clarification. It is unneeded to say that we are very happy with Enhance. And even more with your support.

@kyzoeadmin Average websites are fine. I think they won't hit PHP in most cases due to page cache. Page cache will convert those dynamic pages into static pages. Woo sites will be a real parameter to test. What are the server specs?

Edit: Got the server specs from another thread.
