2. WHAT THIS TALK IS NOT A guide to using x, y, or z web development framework. OR A 100% sure fire way to scale
3. BUT RATHER some of the best practices As well as tools that you will find helpful in your app.
4. QUICK POLL HOW MANY OF YOU ... 1. ... run your own servers? 2. ... runs a website of some sort? 3. ... understands distributed systems? 4. ... has done sysadmin stuff before?
5. WHAT DO YOU GUYS WHAT TO HEAR ABOUT?
6. CLOUDFLARE Provides you with DNS layer caching
9. WHY USE IT?
10. DEMO
11. MONGODB Why MongoDB? 1. It's AWESOME 2. It's FLEXIBLE 3. It's FAST
12. And it’s really easy to do all those hardcore DevOps stuff that you’ve been hearing about. Stuff like High Availability, Sharding, and Backups ...
13. ... Add in the fact that you can add in new fields any time. Fast ...
14. ... and backup your ENTIRE database without facing performance issues
15. WHO USES MONGODB Craigslist, SAP, Codecademy, Disney, IGN, EA, Guardian, Business Insider, Forbes, New York Times, CNN, Trello, bit.ly, Eventbrite, Foursquare, College Humor, Justin.tv, Grooveshark, about.me...
16. KEY CONCEPTS
17. SHARDING
18. HOW IT IS DONE? Spiltiing data into logical chunks based on a predefined shard key
21. REPLICATION “Replication in computing involves sharing information so as to ensure consistency between redundant resources, such as software or hardware components, to improve reliability, fault-tolerance, or accessibility. - Wikipedia”
22. HUMAN SPEAK “Storing your data multiple times in multiple locations and praying hard that all of them do not die at the same time.”
27. Reads on any of the nodes Writes only on master node Eventually correct data
28. MERGING THE 2
32. DEMO I am going to take a live production server down Really Geekcamp.SG's server
33. SETTING UP MONGODB MongoDB website
34. MIXPANEL Awesome Analytics site. Allows you to see ALL your stats in real-time
35. USING IT As simple as m i x p a n e l . t r a c k ( " B u t t o n c l i c k e d " ) ;
36. DEMO
37. HOW DOES IT ALL COME TOGETHER?
38. DEMO GEEKCAMP.SG'S CODE Github link
39. SELF INFLICTED PAIN
41. NETFLIX SIMIAN ARMY Chaos Monkey Latency Monkey Conformity Monkey Doctor Monkey Janitor Monkey Security Monkey Chaos Gorilla
42. CHAOS MONKEY Shuts down instances randomly Allows the team to learn about weaknesses in the system Gets the team to build auto recovery systems
43. LATENCY MONKEY Introduces artificial delays in api client-server communication layer Simulates server degradation Useful for testing fault tolerance of new services
44. CONFORMITY MONKEY Shuts down servers that don’t adhere to best practices Forces the service owner to relaunch them properly
45. DOCTOR MONKEY Runs checks on health of servers Remove unhealthy servers from service and alerts service owner
46. SECURITY MONKEY Scans for security violations or vulnerabilities Ensures that SSL and DRM certs are not expiring
47. CHAOS GORILLA Shuts down all instances within an availability zone Talk about overkill
48. BEST PART IS SIMIAN ARMY IS ENTIRELY OPEN SOURCE Github link here!
49. NEW RELIC
