<font face="arial" size="2"><p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;">Hi Marc,</p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;"> </p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;">Many thanks for your prompt response.</p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;"> </p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;">This addresses one part of the puzzle. I can't speak for Eddie, but as a total DevOps noob, a big-picture perspective would give me greater comfort as I move into my own deployments.</p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;"> </p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;">I'm guessing that there are different issues if we're considering on-premises vs. cloud deployment, so considering the two hosting scenarios...</p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;"> </p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;">What are the specific security, scaling, or other issues we need to attend to? And how do we implement them? For instance, if on-premises: Do we need a dmz to protect our LAN or is port-forwarding sufficient? Should we put a proxy server such as nginx or HAProxy in front of our app? How can we most effectively harden our servers and applications against exploits?</p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;"> </p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;">I understand much of this goes beyond the realm of Zotonic, Erlang, and Nitrogen. But when I step out into the web for answers I'm totally overwhelmed with confusing and oft contradictory info.</p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;"> </p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;">I'd love to create a living-document tutorial and checklist for, at least, the simplest deployments, but wouldn't know where to start.</p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;"> </p>
<p style="margin:0;padding:0;font-family: arial; font-size: 10pt; overflow-wrap: break-word;">Thanks again,</p>

<div id="SafeStyles1547489469">Hi Eddie and Lloyd,
<div class="">“It depends” is indeed the correct answer...<br class="" />
<div class="">Most Zotonic installations fall in two categories:</div>
<div class="">1. Deployment via a Docker container, which is updated before deployment</div>
<div class="">2. Deployment via git (manual or automatic)</div>
<div class="">Some follow (1), I follow (2).</div>
<div class="">Nice thing of (2) is that it allows for hot code upgrades and quick turnaround of small patches.</div>
<div class="">When we are i a development cycle for new features we might have 10 to 20 deployments per day.</div>
<div class="">This goes very smooth, we even deploy minor updates to Zotonic and dependencies using hot code upgrades.</div>
<div class="">Zotonic itself can watch changes in the file system and dynamically load new files.</div>
<div class="">
<div class="">Most of the updates we deploy have only minor changes.</div>
</div>
<div class="">Think of changes to templates, css, or translations.</div>
<div class="">And minor Erlang changes (ie. not completely new apps or other dependencies).</div>
<div class="">That is why we can have updates-via-git without service interruption.</div>
<div class="">The orgs that deploy via Docker (option 1) - have typically less frequent updates and perform periodic major updates.</div>
<div class="">As the whole container is updated this also restarts the Zotonic server.</div>
<div class="">Of course it is also possible to deploy using the OTP release mechanism.</div>
<div class="">This is something that will be possible with the 1.0 (really soon now) of Zotonic, as that version is OTP compliant.</div>
<div class="">I personally never had the need to use OTP releases as the version control via git is good enough for us.</div>
<div class="">(Especially with rebar3 managing versions of dependencies.)</div>
<div class="">Cheers, Marc</div>

<div class="" style="margin: 0px; padding: 0px; font-family: arial; font-size: 10pt; overflow-wrap: break-word;">I'm in a similar situation--- planning soon to release a Nitrogen web application but feeling profound apprehension since I don't have a clear understanding of risks and how to minimize them.</div>

<div class="" style="margin: 0px; padding: 0px; font-family: arial; font-size: 10pt; overflow-wrap: break-word;">No doubt the flip answer is, "It depends..." Are we talking cloud hosting or on-premises? What are projected traffic patterns? Etc. Etc.</div>
<p class="" style="margin:0;padding:0;margin: 0; padding: 0; font-family: arial; font-size: 10pt; overflow-wrap: break-word;"> </p>
<div class="" style="margin: 0px; padding: 0px; font-family: arial; font-size: 10pt; overflow-wrap: break-word;">But "It depends..." doesn't help folks like us who lack experience or organizational support.</div>
<p class="" style="margin:0;padding:0;margin: 0; padding: 0; font-family: arial; font-size: 10pt; overflow-wrap: break-word;"> </p>
<div class="" style="margin: 0px; padding: 0px; font-family: arial; font-size: 10pt; overflow-wrap: break-word;">One can find considerable information on the web covering firewalls, proxy servers, load balancers, site hardening, etc. But, like you, I've found little in the Erlang corpus that provides sufficiently clear patterns and guidelines to assuage my Erlang release/production apprehensions.</div>

<div class="" style="margin: 0px; padding: 0px; font-family: arial; font-size: 10pt; overflow-wrap: break-word;">It may well be a book-length topic or more, but even a thoughtful, thorough tutorial, or even a checklist, would be helpful.</div>

<div class="" dir="ltr">Hi,
<div class="">I have followed zotonic for the last couple of years and am now interested in setting up a production server for zotonic.</div>
<div class="">I have just spent some time searching zotonic users and zotonic developers for an up to date guide on how you would go about developing and deploying zotonic to a production environment.</div>
<div class="">most of the links I found range from between 2010 - 2012.</div>
<div class="">I have looked through the zotonic documentation as well.</div>
<div class="">I have also installed locally using the zotonic full docker container and the manual install.</div>
<div class="">I am looking for a guide for Git / continuous integration / continuous deployment guide and any best practice tips.</div>
<div class="">Is something like this available?</div>
<div class="">Many thanks</div>
