Scale your PHP application with Elastic Beanstalk - CloudParty Genova
1 like2,797 views
This document discusses how to scale a PHP application using ElasticBeanstalk. ElasticBeanstalk allows running applications across dynamically sized fleets of EC2 instances that are managed using simple configuration files. It handles tasks like deploying code and configuration changes, monitoring and scaling application traffic. Some key points discussed include running different environments for development, testing and production; using Composer to manage dependencies and configuration; customizing using .ebextensions files; and monitoring and collecting logs.

Scale your PHP application with Elastic Beanstalk - CloudParty Genova
- 1. Scale out our PHP application with ElasticBeanstalk
- 2. About me Cofounder Cofounder Corley S.r.l. - @CorleyCloud UpCloo LTD - @UpCloo on Github on Twitter wdalmut walterdalmut - Internet Of Things! @ Turin [CFP] - 15 Nov - CloudComputing @ Turin [CFP ASAP] internetof.it www.cloudconf.it
- 3. ElasticBeanstalk Scale your app workers and web apps Queue Daemons Load balanced web applications Mainly for Service Oriented Architecture
- 4. Autoscaling applied to web applications
- 5. Scale apps is not simple How to handle dev/testing/production? (dynamic env) How to install/update softwares? (dynamic env) How to handle user sessions? (more than one node) How to handle/tail logs? (dynamic env) How to monitor all instances (dynamic env) And more... (all things are moving!)
- 6. Run different environment per app Typically you run: Production, Testing, Development
- 7. Different app versions per environment Easy distributed app deploy/rollback and testing/production application management
- 8. Different configuration per environment Upgrade your environment and switch your production without downtime
- 11. Add a new environment
- 12. Swap production environment ElasticBeanstalk swap env URLs in order to simplify the upgrade
- 13. Destroy your old environment COST-SAVING! it is easier create and destroy environments than upgrade them
- 17. Application variables All environment variables are ported to your application in $_SERVER You can pass everything like: Memcached and Mysql configurations etc.
- 18. Use Composer for Dependencies ElasticBeanstalk uses composer in order to prepare your application Use composer hooks in order to connect all env variables to your app configuration
- 19. Composer hooks { /** other composer configs **/ "scripts": { "post‐update‐cmd": [ "CorleyDeployMagento::updateConf" ], "post‐install‐cmd": [ "CorleyDeployMagento::updateConf" ] }, }
- 20. <?php namespace CorleyDeploy; use ComposerScriptEvent; class Magento { public static function updateConf(Event $event) { if (array_key_exists("OVERWRITE_CONF", $_SERVER)) { // Update your config file when $_SERVER contains "OVERWRITE_CONF" variable } } }
- 21. Need more customizations? Create a folder in your project root with name .ebextensions and append your configuration files with extension .config ElasticBeanstalk will use them during the application provisioning
- 22. Cronjobs runs on the leader instance only .ebextensions/05_cron_jobs.config container_commands: 01_magento_cron_job: command: "cat .ebextensions/magento_cron_job.txt > /etc/cron.d/magento_cron_job && chmod 644 /etc/cron.d/magento_cron_leader_only: true All configuration files are just simple YAML files
- 23. Monitor your environment You can monitor many metrics with CloudWatch UDP/IP CloudWatch agent on local machine: https://github.com/wdalmut/cloudwatch-agent
- 24. What we are missing? Logs!
- 25. Grab all active instances logs
- 26. But my application logs? commands: 21_application_logs: command: echo "/var/app/current/var/log/*.log" > myapp.conf cwd: /opt/elasticbeanstalk/tasks/bundlelogs.d 22_application_logs: command: echo "/var/app/current/var/log/*.log" > myapp.conf cwd: /opt/elasticbeanstalk/tasks/systemtaillogs.d 23_application_logs: command: echo "/var/app/current/var/log/*.log" > myapp.conf cwd: /opt/elasticbeanstalk/tasks/taillogs.d 24_application_logs: command: echo "/var/app/current/var/log/*.log" > myapp.conf cwd: /opt/elasticbeanstalk/tasks/publishlogs.d .ebextensions/06_prepare_logs.config
- 27. Collecting all application logs AWS ELB can store all logs into a S3 bucket using a scheduled system COST-SAVING! we don't need to propagate logs via "rsyslog"
- 28. Thanks for listening Any question?
