Background
I need to build an über-scalable web service. It will
be the next big thing!
Easy! I will use node.js and MongoDB!
Easy! I will use node.js and MongoDB!
Because node.js is “scalable”, right?
None
This Talk
#1 Consider Reality
Using node for performance reasons?
Measuring performance in production?
1000 req / s
100 req / s
10 req / s 10 req / s
~1 million requests per day
~1 million units of value
None
#2 Node Scales Vertically
Adding more resources to a single node
None
CPU
Google V8
JS -> Assembly
Crankshaft JIT
Fast
Single Threaded* * For most parts
Computers of the future will have hundreds of cores!
Node’s Multi-Core Story
Pre-fork
IPC
Like Ruby, Python, PHP, etc.
But ... shared memory?
Your problem requires shared memory?
JavaScript is not your language
Good Luck
Memory
No hard limit on 64bit (since node-0.6 / v8-3.7)
However
Avoid huge heaps
Disk
Done in thread pool
Along with DNS
No sendfile()
None
Network
None
Non-blocking I/O
tl;dr
pre-fork & non-blocking i/o
#3 Horizontal Scaling is hard
CAP
Network Partitions
Consistency
Availability
Some Tips
Shared Nothing
Messaging
Monitoring
The Node.js Scalability Myth
Threads do not scale Node.js scales
