How DropBox scales up in Amazon AWS cloud.

 

Rajiv Eranki on the infrastructure used for scaling up DropBox.

 

• Python for virtually everything; not more than a couple thousand lines of C

• MySQL

• Paster/Pylons/Cheetah (web framework — minimal use beyond templating and handling form input)

• S3/EC2 for storing and serving file blocks

• memcached
in front of the database and for handling inter-server coordination

• ganglia
for graphing, with drraw for custom graphs like the stack graph mentioned above

• nginx
for the frontend server

• haproxy
for load balancing to app servers, after nginx (better configurability than nginx’s balancing modules)

• nagios
for internal health checks

• Pingdom
for external service monitoring and paging

• GeoIP
for mapping IPs to locations
