 ====== wiki.opennic.org infrastructure ====== ====== wiki.opennic.org infrastructure ======
-The wiki.opennic.org website runs on [[https://aws.amazon.com/|Amazon Web Services (AWS)]] infrastructure and uses various services offered by AWS:+==== Maintainers ==== 
 +  - [[/user/fusl]]
  
-===== Elastic File System ===== +===== The Infrastructure ===== 
-The [[https://aws.amazon.com/efs/|EFS service]] is used to store all wiki pages, configurations, attachments, etc. on a scalable, shared filesystem using NFS as protocol.  +The wiki.opennic.org website runs as simple virtual machine on Fusl's private infrastructure for open source projects shared with [[https://www.archiveteam.org/|Archive Team]] and others at [[https://nforce.com/|NFOrce]] in the Netherlands (Nedzone Datacenter).

-  * //Endpoint: ''fs-ee48faa7.efs.us-east-1.amazonaws.com''// +
- +
-===== ElastiCache ===== +
-[[https://aws.amazon.com/elasticache/|ElastiCache]] stores all PHP sessions in a single Memcached instance to ensure session and login-state persistency and reliability across all floating wiki.opennic.org webserver instances. +
- +
-  * //Endpoint: ''prod-wiki-sess.xqtznt.cfg.use1.cache.amazonaws.com:11211''// +
- +
-===== Auto Scaling ===== +
-To automatically scale the wiki instances to the desired performance and to ensure reliability even on instance failures, we use an [[https://aws.amazon.com/autoscaling/|Auto Scaling]] group which handles automatic scaling at your desire. +
- +

- +
-==== Scaling Policies ==== +
-=== prod-wiki-high === +
-  * //Policy type: ''Simple scaling''// +
-  * //Execute policy when: ''prod-wiki-high'' (breaches the alarm threshold: ''TargetResponseTime >= 1'' for *300* seconds for the metric dimensions ''LoadBalancer = app/prod-wiki/0ec4b8b4601b350c'')// +
-  * //Take the action: ''Add 2 instances''// +
-  * //And then wait: ''180 seconds before allowing another scaling activity''// +
- +
-=== prod-wiki-low === +
-  * //Policy type: ''Simple scaling''// +
-  * //Execute policy when: ''prod-wiki-low'' (breaches the alarm threshold: ''TargetResponseTime <= 0.5'' for *300* seconds for the metric dimensions ''LoadBalancer = app/prod-wiki/0ec4b8b4601b350c'')// +
-  * //Take the action: ''Remove 1 instances''// +

 +==== git sync ====
 +The entire web root directory is synced to [[https://github.com/opennic/wikipages|GitHub]] approximately every 60 minutes using a [[https://github.com/opennic/packers/blob/master/opennic-wiki/files-pre/etc/cron.hourly/gitsync|crontab script]]. Some files are [[https://github.com/opennic/wikipages/blob/master/.gitignore|excluded]] from being synchronized to the git repository.
