1. What is Cloud Computing?

- Utility computing- Ready made appliances and

services, just “plug in” and go- Started out as spare cycles

and platform APIs from Amazon- Now open competition from

Google, Microsoft, and others- IT spend as opex, not capex

- Pay as you go

-Infrastructure as a Service (IaaS)- Bring Your Own OS, software, etc- Public, private, hybrid clouds

-Platform as a Service (PaaS)- APIs and standards to code against, e.g. storage,

database, IP load balancer

-Software as a Service (SaaS)- Typically admin dashboard, application level APIs

and user facing Web services

Opportunities:- Capacity planning needed to assess

resource for move into the cloud- Server virtualization expertise - Data centre design and build- Sysadmins to run operating systems,

install and maintain software etc- Hot topic: Live migration of workloads

1. What is Cloud Computing? PaaSOpportunities:- Building APIs and

data models- Developing and

extending existingopen source code,e.g. Hadoop

- Writing applications against these APIs, e.g. Google App Engine, Amazon Web Services

- Selling cloud applications, e.g. Google Apps Marketplace

$options = array( 'requestScheme' => Zend_Oauth::REQUEST_SCHEME_HEADER, 'version' => '1.0', 'signatureMethod' => 'HMAC-SHA1', 'consumerKey' => $CONSUMER_KEY, 'consumerSecret' => $CONSUMER_SECRET);

$config = new Zend_Oauth_Consumer($options);$token = new Zend_Oauth_Token_Access();$httpClient = $token->getHttpClient($options);$client = new Zend_Gdata_Docs($httpClient);

$feed = $client->getDocumentListFeed('https://docs.google.com/feeds/documents/private/full?xoauth_requestor_id=' . urlencode($email_address));foreach ($feed->entries as $entry) { $title = $entry->title; # etc}

Opportunities:- Migration assistance- Systems integration, e.g. use APIs to

import/export data- Day-to-day administration- Use APIs to extend existing services, e.g.

Gmail contextual gadgets- Develop new SaaS offerings

- It's just a website, really :-)

4. Dark Clouds and Silver Linings

2. Why use it?

- Provision service rapidly- Flexibility over scaling- Reduce headcount, power

bill, cooling requirements- Convert capital expenditure

into operating expenditure- Concentrate on stuff that

genuinely adds value
