way from legacy to cloud

1. Way to Cloud
Andrew

2. Why, Cloud?
• Application with seasonal traffic requirement
• Disaster recovery
• Test environments
• Fast provisioning

3. Why Cloud, Really?
• Application with seasonal traffic requirement
• if you can predict it, you can take other arrangements
• Disaster recovery
• AWS can help, but AWS doesn’t provide all
• Test environments
• more important thing is stitching with production
• Fast provisioning
• tens of server can be propared in a few hours too.
• provision is one thing, operation is others.

4. Before change
• Simplify
• Standardize
• Automate
• Abstract

5. After that
•You’re ready for the cloud

8. Simplify & Standalize
• Simplification mostly means simple process
• Your resources should be provided in same way
• Using Central Configuration system
• Using Central logging/monitoring system
• Using standard/common API

9. Automate
• Try to avoid manual setup or intervention.
• Every process should be programmed. ( need code
and developer)
• need event based processing ( need central
coordination )

10. Setup your app in
Simple, Standardazied, Automated Way
configuration
Repo
(Cookbooks,
Custom App.
Repo
(tested)
PHP Server (VM)
MySQL Server (VM)
Develop Env.

11. Setup Dev
• Create Cookbooks for PHP and MySQL
"recipe[opsworks_initial_setup]",
"recipe[ssh_host_keys]",
"recipe[ssh_users]",
"recipe[mysql::client]",
"recipe[dependencies]",
"recipe[ebs]",
"recipe[opsworks_ganglia::client]",
"recipe[mod_php5_apache2]",
"recipe[deploy::default]",
"recipe[deploy::php]",
"recipe[phpapp::appsetup]",
"recipe[agent_version]",
"recipe[php::configure]"
"recipe[opsworks_initial_setup]",
"recipe[ssh_host_keys]",
"recipe[ssh_users]",
"recipe[mysql::client]",
"recipe[dependencies]",
"recipe[ebs]",
"recipe[opsworks_ganglia::client]",
"recipe[mysql::server]",
"recipe[deploy::mysql]",
"recipe[phpapp::dbsetup]",
"recipe[agent_version]"

12. Abstraction
• Use identical tool for the bringing up the server
• Chef API , and tools
• To inintiate Server
• vagrant up

13. Setup Dev.

14. Time for the production
AWS Provides Chef server:
* You can use the same
configuration tool
* You can use the same
management tool
* from this, you can have
identical but little bit different
experience

15. Bringing up the Production
AWS Opsworks

16. Again Same tool
• Remember the command line?
• vagrant up

17. Bring up the Prod.

18. things to know
• Cloud should be a tool that your express your long &
deep experience.
• AWS has lots of way to help you.
• EC2, RDS, S3 for basic operation.
• SQS, SWF, ELB, Route53 and other services for
comprehesive use.
