Scalability for Dummies
http://ift.tt/1nKSGEZ
Public servers of a scalable web service are hidden behind a load balancer.
Every server contains exactly the same codebase and does not store any user-related data, like sessions or profile pictures, on local disc or memory.
Sessions need to be stored in a centralized data store which is accessible to all your application servers.
It can be an external database or an external persistent cache, like Redis.
Use ASW AMI.
http://ift.tt/1QYKb4e No-join, use NO-SQL.
Scalability for Dummies - Part 3: Cache
Use Redis or Memcached.
#1 - Cached Database Queries
#2 - Cached Objects
I love the extra database-features of Redis like persistence and the built-in data structures like lists and sets.
Scalability for Dummies - Part 4: Asynchronism
http://ift.tt/1GH9dW2
Async #1
Pages of a website, maybe built with a massive framework or CMS, are pre-rendered and locally stored as static HTML files on every change.
Async #2
Try RabbitMQ or ActiveMQ.
