/about/me
“There’s a module for that!”
•Multiple response format (REST, XMLRPC,JSON, JSON-RPC, SOAP, AMF)
•Pluggeble access control•Amazing integration with available
modules(Views, System, node, taxonomy, authentication ... )

“If all you have is a hammer, Everything looks like a nail”
1.7 GB of Ram
Small ec2 instance
Gavri’s App
1500 / 30 = 50 Concurrent
All Memory - 1700MBFree Memory - 1500MB
Avg Drupal process size ~ 30MB
Introducing Node.js“Node is a server-side JavaScript interpreter that changes the notion of how a server should work. Its goal is to enable a programmer to build highly-scalable applications and write code that handles tens of thousands of simultaneous connections on one, and only one, physical machine.”

“Node is a server-side JavaScript interpreter that changes the notion of how a server should work. Its goal is to enable a programmer to build highly-scalable applications and write code that handles tens of thousands of simultaneous connections on one, and only one, physical machine.”
Introducing Node.js• Built on the V8 engine (chrome’s very fast browser engine).• Can handle thousands of concurrent connections with minimal overhead.• Ability to share code between server and client• Vibrant Community• Great package management (npm)
1500000 / 100 = 15000 Concurrent
All Memory - 1700MBFree Memory - 150000k
example node.js process size ~ 100k
“But If we improve concurrency
by 500X won’t that just - Jam Mysql even more?”
Introducing MongoDB• Document oriented storage• Full index support (+geo)• Replication and High Availability• Querying • Map Reduce
• speak Javascript• “Understand” json documents• Are Very fast• are very popular and together are a path well traveled (relatively speaking)
Both:+
When To use this pattern? • JSON API’s• Single Page Apps• Shelling out to unix tools• Streaming Data• Soft Realtime Applications
When NOT to use this pattern? • CPU Heavy tasks• Simple CRUD / HTML apps• Just for the BuzzWord compliance.
Let’s look in depth in to one of these usecases...
• JSON API’s• Single Page Apps• Shelling out to unix tools• Streaming Data• Soft Realtime Applications
1. Node based API Server serves mobile/widgets etc..
2. MongoDB database stores state.
3. Services module dealswith interacting with Drupal
4. Drupal is the front for content creation
