![]() ![]() Is your development environment as secure as production? Loosely monitoredĭevelopment machines are a common attack vector for black hats. If you’re considering this approach, also consider a few major It’s common to see people using a replica of the production database One problem with maintaining a good development environment is populating it Always favor pure isolation over exact parity in that battle. You don’t want yourĭevelopment environment processing payments or sending files to your productionĬDN. For example, you’ll definitely need toĭiverge in your third-party service configurations. Places where it conflicts with the goal of environment isolation. In your effort to reach environment parity, you’ll hit There are few things more maddening for a developer than aīug that only shows up in production because of a lack of parity in theĭevelopment environment. Things in development without taking down production services.Įach environment should be as close to production as possible (settings, Your team needs to have confidence that they can break Maintain parity, but reduces the cost of running non-production environments.Įach separate environment should be completely isolated from the others,Įspecially production. On a low-traffic development server, all these servicesĬould run together on the same machine. For example, in production, you may have separate server(s) for Varnish, (fewer resources per server), but try to keep the same general server/service You can scale back both horizontally (fewer servers) and vertically Infrastructure becomes financially infeasible for development and Plan on having at least two (staging/development and production).Īs your production server farm gets larger, running an exact replica of its The number of environments you have depends on your work-flow, but Give your team a place to stage new features for feedback, QA builds beforeĭeployment, or test infrastructure changes without taking down production Website, but critical for large-scale operations. Having multiple remote environments you can deploy to is a good idea for any Of ways 4 to do this, perhaps the most convenient being the Gracefully reload instead of doing a hard restart. Momentarily taking down an app server could drop Once your site is up and running, you want to be very carefulĪbout restarting services. Salt has remoteĮxecution baked in so that’s what we use, but Fabric is also a great option. Anything moreĬomplicated than one step is an opportunity for human error to creep into theĪ remote execution framework is the right tool for this job. You can simplify this multi-step process by scriptingĮverything so it only requires a single click or command. Shipping a new build usually requires a number of steps:Ĭheckout the latest code from version controlĬollect, compress, and push static files to CDNĪs with the rest of the process, simplicity is the key to making deployments If you find yourself fighting with it, consider choosing ![]() Whatever you choose, this should be one part of your Description = My Service After = syslog.target ExecStart = /path/to/my-service Restart = always User = myuser Group = mygroup WantedBy = multi-user.targetĪlternatively, you may find daemontools 1, supervisord 2, or circus 3 Like Ansible and Salt are making headway. Chef and Puppet have a lot of mind-share, but Python-based tools Management space systems and the decision really comes down to experience and There are lots of options in the configuration If they have divergent configurations orĭifferent software versions you’re gonna have a bad time.Ĭonfiguration management lets you define what it means to be an “app server”Īnd roll out new ones at will. Reliable deployments are impossible without a stable homogeneous platformĪcross all your servers. Ubuntu LTS versions so we don’t have to rebuild It will have security updates into the foreseeable future. CentOS/RHEL are notorious for being a version or ![]() If you can’t easily use Python 3.5 or higher,Ĭhoose another platform. Unless you have lots of experience working with anotherĭistribution, just choose Ubuntu. Preferred distribution amongst Django developers but there are many other Unix/Linux based systems rule the land for Django deployment. For high-traffic sites, however, a PaaS may be cost-prohibitive or Massive amounts of time over building (and maintaining) everything from If you can get away with using a PaaS such as Heroku, it can save you
