7. How to rule the world?
or

8. Start gathering requirements
 What is the goal of the project?
 What is the expected number of users/ page views during the peak load, what is the expected number of pages
on the website?
 What is the structure of the website and what types of content will be published?
 Which web standards should be followed in terms of accessibility and coding?
 Who is the target web site visitor?
 Which products and technologies will be used?
 What is the content life-cycle? Who is responsible for the content management?
 What languages will be used for the content?
 What is the required availability of the website?
 What is the production environment type?

9. Architecture ready for the future

10. Azure architecture
Internet
SQL DatabaseWeb App
Redis Cache
Azure Traffic Manager
CDN

11. Azure regions
https://azure.microsoft.com/en-us/regions

12. Tips and tricks: Architecture
http://www.submarinecablemap.com

13. Gotcha: Geo-replication
 Kentico does not support read-only
SQL databases
 Hosting the SQL Azure database
outside the Azure Region results in
a huge performance degradation

14. Azure architecture (per region)
Internet

15. Demo – Architecture

16. Multi-Tenancy
Ability to have multiple sites installed in a single installation of
Kentico
 Multi-site objects and content
 Integration
 Governance
 Search
 Marketing
 Software Maintenance / upgrades

17. Gotcha: Multi-Tenancy
Some of the early Kentico modules don’t work very well with
multi-site objects
How we handled it:
Create custom modules and enforce the use of the SiteID column

18. Example: Multi-Tenancy
 Custom localization module
 Apply hotfix 8.2.39 or newer!

19. Tips and tricks: Multi-Tenancy
 Use global roles and configure required permissions
http://blogs.jeroenfurst.nl/blog/september-2015/working-with-roles-and-permissions
 Create custom modules for non multi-tenant Kentico modules
https://docs.kentico.com/display/K82/Creating+custom+modules

20. Session State
 Single instances  InProc
 Multiple instances (web farms)  Azure Redis Cache
https://azure.microsoft.com/en-us/documentation/articles/cache-faq/#which-azure-cache-offering-is-right-for-me

21. Demo – Session State

22. Tips and tricks: Session State
 Microsoft Azure Redis Cache in Kentico
http://devnet.kentico.com/articles/microsoft-azure-redis-cache-in-kentico
 Typos in Azure Redis Cache access keys can result in headaches
http://blogs.jeroenfurst.nl/blog/july-2015/typos-in-azure-redis-cache-access-keys-can-result

23. Content delivery networks
 Push
Editor uploads files directly to the CDN server
 Origin Pull
CDN fetches data during the first request and caches it
http://www.whoishostingthis.com/blog/2010/06/30/cdns-push-vs-pull/

24. Gotcha: Azure Blob Storage
 Media library limitations when storing files in an external
storage
https://docs.kentico.com/display/K82/Configuring+media+libraries#Configuringmedialibra
ries-Medialibrarylimitationswhenstoringfilesinanexternalstorage
“We recommend storing at most 100 files in a single media library folder.”

25. Tip and tricks: CDN
 Speeding up Kentico Websites with Rackspace CDN and Origin Pull
http://www.getstarted.com.au/Blog/September-2015/Kentico-Rackspace-Akamai-CDN-Origin-Pull
 Upgrade to hotfix 8.2.44 or newer

26. Demo – CDN

27. Web Farms & Kentico 9
 No additional configuration
 Robust, failure recovery and self-healing
 Improved performance (synchronizing physical files)

28. Demo – Web Farms

29. Tips & tricks: Web Farms
 Automatic deletion of inactive WF servers in 8.x
http://devnet.kentico.com/articles/automatic-deletion-of-inactive-wf-servers
 Automatically generate scheduled tasks for web farms
http://blogs.jeroenfurst.nl/blog/august-2015/automatically-generate-scheduled-tasks-for-web-far

30. Ready for liftoff

31. Demo – Deployment

32. Wrapping up
 Architecture
 Multi-Tenancy
 Session State
 Content Delivery Network
 Web Farms
 Deployment
