The document discusses best practices for application deployment including: 1. Using Capistrano for remote deployment with a proper directory structure and symbolic links for releases. 2. Ensuring proper file and folder permissions. 3. Considering backend processes, configuration and management, SEO optimization, version control, code quality, rewrite rules, programming languages, technology, frameworks, libraries, plugins, setup simplicity, efficiency, scalability, performance testing, images, CDN, exception handling, exceptions to hard coding, testing, error pages, database and SMTP configuration, agile development, error logging, access control, SSL, code reviews, performance, stability, operations strategy, production deployments, maintenance pages, continuous integration

2. 1. Proper skeleton using Capistrano remote deployment.
Directory Structure as follows:
myapp/releases
|_ 20081019001122
20081019001123
myapp/current -> releases/20081019001122 # Sym link
current.
myapp/shared
|_ images
config
|_ config.php
myapp/system
|_maintenance.html

3. 2. Proper Permission.
File's and Folder's

4. 3. Backend process
Configuration And Management.

5. 4. SEO optimization.
Check which URLs feeds are
submitted to webmaster.

6. 5. Source code under Git
(Version Control).
Maintained Branches as per
release.

02/Deploying-websites-with-Git

7. 6. Source code should be Clean.
(Do not push any unused file/folder's in
that)

8. 7. Rewrite Rules / URL's

9. 8. Should be use oops Language's like:
Python, Ruby, Jruby, Java for
Frontend and Backend for
application scalability.

10. 9. Always use and work on
cutting edge technology.

11. 10. If using Check
Framework/API/Library/Plugins
versions for Application.

12. 11. Simple and quick
setup.

13. 12. Check Efficiency and
Scalability.

14. 13. Stress testing with using
testing tools
Like: Apache benchmark
(ab)

15. 14. Check the performance
tool. i.e. yslow and firebug.

16. 15. Images should lightweight for
serving. Create in .PNG format from
designer.

17. 16.CDN setup and update DNS records for
serving only static content.

amazon-s3-as-an-image-hosting-service.html

18. 17. Exception notification for
Application.

19. 18. No hard coding please.

20. 19. Bug/Testing resolve
dependency.

21. 20. Error Pages. ( If the links
broken)
use 404 for not found.
if break URLS redirect to
home
path.

22. 21. Only one DB and SMTP config
file
for each application.
Do not add DB connection and SMTP
in any .php file.

23. 22. We all should know and
follow
the Agile Development.

_software_development

24. 23. After production deployment will
not
change any things manually.
If we found it should to update it
will
go in next release.

25. 24. Enable Error Logs and Access
Logs
for Application

26. 25. Add SSL for site if there is any
account activity done.

27. 26. Understanding of software
designing.

28. 27. Good in estimation.

29. 28. Involved in code review and
check coding stranded. With PM,
Dev, Operation Team.

30. 29. Contribution towards
performance, stability and
operation
of the app

31. 30. Strategy:
Start
1. create revision and functionality for the
release.
2. List the changes and To do's in revision.
3. Updates on local/staging
4. Testing and Bug fix.
5. Push to production.
End.

32. 31. Production deploy only on
weekdays Tuesday or Wednesday, so
everyone in office.
Starting Time: 10:00 Am
End Time : 5:00 PM #After that
will stop deployment.

33. Planning2

34. Proper Planning and discussion.
All should be on same page.

35. If site down should show
Maintenance page on website.

36. Continuous Integration and Proper
development and deployment

37. Do major services optimization.
Httpd, mysql, if any other.

38. Database side optimization.
Do plan which database is
suitable for our application.
e.g.
pgsql,nosql,mongodb,mysql,percona,tok
yo cabinet

39. Database Slow query optimization.
Make it to faster to them.

40. Master-master, Master-slave, Multi
master environment.

41. Mail server configuration.
All set with mail server
prospective.

42. Work on critical task.

43. Proper server management by server
admin only. There will no any kind
of access for developers.

44. Backup and Restoration plan and
management.
AWS S3, NFS. Volume,
Snapshot, Backup Directory.

45. The good comes not from the
code or the features,
but process standardization.
