+ ?!

We love Ruby on Rails

And other languages/frameworks you secretly love ;)

puts 'Hello world'

Useful NOT!

THE RAILS “STACK”

load balancers

LOAD BALANCERS Pound, Varnish, Pen, hardware solutions, etc…

LOAD BALANCERS Part of the platform Any available TCP port Can pull VMs in/out of rotation

REVERSE PROXIES mod_proxy, Perlbal, nginx, …

REVERSE PROXIES Works the same way

app/web servers

APP & WEB SERVERS Many, many combinations possible Most work great

APP & WEB SERVERS

GEMS Package with app At runtime, use Gem::GemRunner or “ gem install ” Caveat – Not all gems build/work on 64-bit Windows

data

MYSQL Runs great on Windows Azure

MYSQL Solution Accelerator Master/slave, scale up and down slaves, periodic backups

WINDOWS AZURE CLOUD STORAGE SERVICES SQL Azure BlobsTablesQueues

SQL Azure Cloud-based relational database service Scalable, available, fault-tolerant Works with T-SQL based libraries/tools

SQL Azure Use activerecord-sqlserver- adapter Patch using

Storage Services Public REST APIs waz-storage gem good starting point

Blobs Simple interface for storing named files with metadata Very large objects (upto 1TB in size per blob) Available through a CDN frontend

require 'waz-blobs‘ WAZ::Storage::Base.establish_connection!( :account_name => account_name, :access_key => access_key) container = WAZ::Blobs::Container.create('my-container‘) blob = container.store('my_blob.txt’,'some content’) blob = container['my_blob.txt']

Queues Reliable delivery of messages Drop-in replacement for beanstalkd, starling, worker systems

WAZ::Storage::Base.establish_connection!( :account_name => account_name, :access_key => access_key) queue = WAZ::Queues::Queue.create('my-queue') queue.enqueue!("some message")

Tables Structured data at scale Efficiently insert, query and retrieve millions of entities

entity = { :first_name => ‘William', :last_name => ‘Adama', } service.insert_entity('customer_table', entity) service.query('customer_table', {:expression => "(last_name eq ‘Adama‘)", :top => 2} )

caching

memcached winazurememcached

day to day

Deployment Comes with the platform.

Deployment Use service management API to automate E.g : Deploy packages as a part of your Rakefile

Management Comes with the platform.

Management Use service management API to configure, upgrade, scale up/down Use monitoring/diagnostics API to replace nagios/ganglia

Debugging debug, to_yaml helpers work OOB Standard logger works great, logs to RAILS_ROOT/logs. Use diagnostics API to retrieve

THINGS TO REMEMBER Open platform Works well with Ruby world Jump in!
