Squiz Hosting
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
Squiz Hosting – An Introduction
> We have an international footprint
Squiz Hosting – Some of our Clients
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.
Primary Site Review - GlobalSwitch
> Carrier Neutral – peering between providers is unrestricted.
Primary Site Review - GlobalSwitch
> Currently undergoing a $200M expansion project
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 Berkeley NOW Project “Networks of Workstations”
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
What if I want to upgrade?
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
The Squiz Cloud – How it came to be
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.

If Squiz don’t control the infrastructure, Squiz can’t control the quality.

That’s so last year.
How it came to be
Let’s build a cloud like Google!
Let’s build a cloud like Google!
> It should scale horizontally, without an expensive SAN (Enables affordability)
> We should be able to provision remotely (Enables agility)
Let’s build a cloud like Google!
> We should be able to resize your services (Enables scalability)
Let’s build a cloud like Google!
> 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
