Squiz Hosting – An Introduction
Squiz Hosting operates out of 4 main locations:
> GlobalSwitch Sydney, AU> TransACT Canberra, AU> The Bunker #1 Kent, UK> The Bunker #2 Newbury, UK
The Squiz Network
> No contractors - owned & operated by Squiz
> Provides redundancy - Squiz connects to 4 upstream providers
> Allows portability - Squiz owns its own (IPv4 & IPv6) address space on the internet
> We control and maintain our own redundant routers, firewalls and switching infrastructure.
Primary Site Review - GlobalSwitch
> Located in Sydney, outside the CBD evacuation zone. > Most of the major domestic and international fiber
paths terminate in the same area.
Primary Site Review - GlobalSwitch
> 34MW of power to the datacenter provided by two diverse feeds.
> Protected by 22 no-break diesel generators.
Question> The first demonstration of how to build very large internet
sites using large clusters of computers was done by:
> Stanford> Berkeley> Yahoo!> Google> IBM
The Origins of Cloud
The Sun E-10000 “Supermini”> Up to 64 Processors> Up to 64 GB of RAM> Up to 20 TB of Disk> Used by eBay, among others
The Personal Computer > 200Mhz CPU> 32MB of RAM> 4GB Disk
The Origins of Cloud
Access is the killer App!> Data & Services located in
Infrastructure the cloud> Search, email, personal
communications, productivity, etc> The idea of mobile access &
applications evolved. > This requires scalability
The Origins of Cloud
You don’t buy servers anymore!> You buy resources, only what you need
Welcome to utility (aka cloud) computing> A vision of MULTICS (1969).> Enables 1 user/developer to build online services and
scale infinitely as required.
The Origins of Cloud
We live in an age of “Ready, fire, aim”> Online solutions need to be agile, changing strategic
direction should not be difficult
Is your “aaS” covered?> If your organisation’s web presence isn’t provided “as a
Service” – you may be missing the boat. Squiz can help!
Predicted growth has exceeded 500%> Our cloud has gone through 5 significant
expansion phases in under 6 months.
The Squiz Cloud – How it came to be
How it came to be – the challenges
> Affordability (without sacrificing functionality)> Agility (enables rapid deployment)> Redundancy (ensures we meet uptime guarantees)> Scalability (allows customers to survive infrequent
peaks)> The Squiz Suite was born!
How it came to be – Our Options
> Rackspace or Amazon
Offshore hosting doesn’t sit well with our government clients.
> White-label an Australian vendor

If Squiz don’t control the infrastructure, Squiz can’t control the quality.
> Continue to only provide dedicated (dinosaur) hosting

That’s so last year.
Let’s build a cloud like Google!
> It should scale horizontally, without an expensive SAN (Enables affordability)
> The infrastructure needs to automatically heal (Enables redundancy)
Let’s build a cloud like Google!
The Squiz Cloud
> It’s not VMWare!> Did you know VMWare relies on a single point of failure?
WARNING!
The Squiz Cloud – It’s Applogic
> Combines traditional “grid” computing with new virtualisation technologies
> Does not require shared storage devices, all physical nodes combine to form extremely large resource pools
> It is based on open-source virtualisation technologies
