BILLS

AZURE PORTAL ROCKS!

CLOUD APIS

My Services Push notification connections, disconnects, push URI changes

Automated Crash Reports Email crash reports & mail parsing Custom live tile generation App settings & preferences Continuous processing queue

Live tiles, toasts, new users, upgrade logic, special tasks

Platform/version-specific tasks & services

Storage-hosted services What’s new content Known current version number Version-specific kill bits, global kill bit Standard tiles

3rd Party Services Foursquare Google Analytics

3rd Party Tools UserVoice ($0) Tumblr ($0) GitHub ($12)

STAGING & PRODUCTION

Debug builds target my staging environment

Staging uses modified JSON values (keys, certificates, etc.)

Git deployment with Azure Web Sites makes it quick & easy

Production challenges

Version-specific endpoints

Migration between providers

Database and cloud downtime

AUTHENTICATION, KEYS, CERTS… Environment variable MODE assign staging/production value

Environment variable APP assigns service: e-mail processing, worker, web, API host

JSON-based configuration loaded through configuration.js

CONNECTING FROM THE CLIENT APP HttpClient NuGet/PCL

Retry policies, handling HTTP status

GZip Compression

RestSharp

JSON.NET

Caching technology & strategies; AgFx

LOGGING & STATISTICS

Logs Detailed Table storage Per-user Winston (Node.js logger) extension

Stats Statsd, Graphite, Carbon Time scale storage UDP Fire and forget Linux VM on Azure or EC2 Instance

DNS

MIGRATION CHALLENGES

> 150,000 users in active processing

DNS hosting helps w/transitions

Free time

Foursquare is in US-EAST-1 (AWS)

Statsd helps show trends during tests

SCALE

Smart per-user resource allocation

Web Sites Reserved Instances: Size & Count

Mongo-based consistency enables multiple workers

DNS Load Balancing
