1 Cloud Services Architecture Making sense of *aas

2 Topics Quickly about me The cloud - definitions and hype What problems are we trying to solve? A few different views of "the cloud" What's out there now? Microsoft's PDC announcements Cloud services architecture When to use the cloud now? What will it all look like in future? Questions

3 Quickly about me... Ben Reid Enterprise and Solution Architect Clarus member Originally from the UK, moved to Christchurch, NZ in years software dev and architecture working on.net since Beta 1 Last 4 years with HP NZ Recently left HP and founded Memia Ltd: Cloud services consulting Enterprise architecture Cloud architecture tools and methodologies Don't get to do much coding these days

4 About Clarus

5 The cloud - definitions and hype The "cloud", by definition it's a nebulous term 2008 zeitgeist, seems to be sticking "Nephology" = study of clouds Driven by major trends: Ubiquitous(?!NZ?!) broadband internet connectivity Commoditised hardware Virtualization Advances in datacentre cooling Maturing standards for web applications, web services

6 What problems are we trying to solve? Cost Scalability Flexibility Availability Portability Collaboration Enable new stuff that we couldn't do before!

7 Some different "views" of the cloud Undersea cable view Data centre view Cooling view Logical (services) view

8 "The cloud" - undersea cable view

10 The cloud - datacentre view Massive build-out happening right now Google, Microsoft, Amazon, Yahoo are tier 1 HP (EDS), IBM, Rackspace? Scale is key

11 The cloud - datacentre view

12 The cloud - cooling view

13 The cloud - cooling view

14 The cloud - cooling view?

15 The cloud - logical view

16 The cloud - logical view

17 The "cloud" - definitions and hype Is the "cloud": Infrastructure aas? Grid / utility / "on demand" computing Shared utility eg Amazon EC2 Platform aas? Ready-for-deployment scalable application platform Google apps, Force.com, Heroku, Bungee Labs Microsoft! (Azure) Software aas? Used to be called "application service providers" Multitenanted architectures: SalesForce.com,Xero...many, many others (3000 worldwide at least)

18 The "cloud" - definitions and hype...is the "cloud": Wide area SOA? "Universe of all (web) services" WS-* and REST (and Etch?) standards Data as a service? (StrikeIron) *aas? "Universe of all economic services" Can traditional "services" (law, accountancy, plumbing) be included in the logical Cloud?

19 IDC Definitions (Sept 2008) Cloud Services = Consumer and Business products, services and solutions that are delivered and consumed in real-time over the Internet Cloud Computing = an emerging IT development, deployment and delivery model, enabling real-time delivery of products, services and solutions over the Internet (i.e., enabling cloud services) (From

20 IDC: Key Cloud Services Attributes:

21 Cloud business models Consumption Pay-per-use Perpetual licence Renewable licence / Subscription Advertising funded "Bits to objects" Value-add for existing products Build a user community

22 What's out there right now - IaaS Amazon Infrastructure web services EC2 - now with Windows (99.95% availability!) S3 SimpleDB SQS (Simple Queue Service) Payments and Billing On-demand workforce (Mechanical Turk) Search (Alexa) Fulfilment web service Rackspace Mosso JungleDisk SliceHost

23 Amazon EC2 Pricing - Hosting (As at 28/10/2008)

24 Amazon EC2 Pricing - Bandwidth (As at 28/10/2008)

25 Amazon S3 Pricing (As at 28/10/2008)

26 What's out there right now - PaaS Google Apps Python only BigTable Heroku Ruby on Rails hosted on EC2 Force.com Apex Bungee Connect Bungee Logic (a C-family language similar to C#) Microsoft! Azure -.NET hosted in MS datacentres

27 What's out there right now - SaaS

28 Microsoft Windows Azure The Azure Services Platform (Azure) is an internet-scale cloud services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services that can be used individually or together.

29 Windows Azure - Pricing model The Azure Services Platform business model is aligned around four basic principles. These are: * Consumption-based model * Pricing attractive with the market * Market expansion opportunity for Microsoft partners * Easy access through the Web, or through existing channels and programs "Consumption" is based upon: * Compute time, measured in machine hours * Bandwidth requirements (transmissions to and from the Azure data center), measured in GB * Storage, measured in GB * Transactions, measured as application requests such as Gets and Puts "

30 Windows Azure - availability PDC announcement is for CTP, available now. If you dive a bit deeper into the FAQs, you can see the production schedule: * Availability Timeframe H o Acquire directly through the Microsoft Online Customer Portal o Acquire though ISVs (independent software vendors): purchase an ISV application which utilizes the Azure Services Platform, and pay the ISV through their own licensing and pricing model

31 Microsoft cloud architecture guidance

32 What problems will we come up against? 1. Regulatory Issues 2. Legislative Issues 3. Geopolitical 4. Security Vulnerabilities 5. Application Architecture 6. Hardware dependencies 7. Control over your servers 8. Cost of the cloud 9. If it Ain t Broke Don t Fix it (Courtesy John M Willis' Cloud blog)

33 When to use cloud services now? Non-sensitive binary object storage (docs, pdfs, images etc) - use S3 or similar NOW! Moving server hosting to the Cloud: business case needs developing Management tools not mature Not ready for Enterprise apps - but soon Azure will be a key player for PaaS Google, SalesForce(?) main competitors Lots of niches SaaS When setting up a new business, use it now! Don't saddle your business with expensive, inflexible, rapidly depreciating assets you don't need!
