0 likes512 views
The document introduces cloud computing and its various service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), highlighting their benefits like scalability and cost efficiency. It discusses opportunities within each model, such as migration assistance and API development. Additionally, it notes the importance of open source and the potential challenges of using proprietary software.

- 19. Promise of Utility Computing: • 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
- 20. Promise of Utility Computing:
- 21. Infrastructure as a Service (IaaS) o Bring Your Own OS, software, etc o Public, private, hybrid clouds Platform as a Service (PaaS) o APIs and standards to code against Software as a Service (SaaS) o Typically admin dashboard + user facing Web services
- 23. Infrastructure as a Service (IaaS) o Bring Your Own OS, software, etc o Public, private, hybrid clouds Platform as a Service (PaaS) o APIs and standards to code against Software as a Service (SaaS) o Typically admin dashboard + user facing Web services

- 25. IaaS: Hybrid Cloud Example Slide credit: Phil Richards
- 26. IaaS 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 between containers
- 27. Infrastructure as a Service (IaaS) o Bring Your Own OS, software, etc o Public, private, hybrid clouds Platform as a Service (PaaS) o APIs and standards to code against Software as a Service (SaaS) o Typically admin dashboard + user facing Web services
- 28. PaaS Opportunities • Building APIs and data models • Developing and extending existing open source code, e.g. Hadoop • Writing applications against these APIs, e.g. Google AppEngine, Amazon Web Services • Selling cloud applications, e.g. Google Apps Marketplace
- 29. PaaS: Google API example
- 30. $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 }

- 32. SaaS example: Google Apps Gmail Huge inbox with search: keep and find everything. Talk Business class IM and VC as easy as email. Groups Let users easily create and work in teams. Calendar Make sharing calendars and schedules easy. Docs Makes collaborating as easy as creating Sites Allow users to manage their own sites. Postini Security and compliance solutions. Marketplace Extend the functionality of Google Apps Slide credit: Ross Mahon, Google

- 34. Continuous Innovation Discussions Apps for Chrome for in Docs 60+ new Apps Business Apps Docs Cloud Chrome Priority Chrome Mobile Connect 4 Browser Inbox books Editing Office 2010 2011 218 feature releases 95 so far… 2008 2009 . 2010 2011 150+ releases 68 releases 116 releases 217 releases already!

- 37. SaaS 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 o It's just a website, really :-)
