Amazingly attended seminar featuring - Salesforce- VMWare - ILB Computing - my notes 1.Roger Parrish - VM Ware ex ATO - sales hype! -
- IT as a service aka Cloud
- recapped mainframe 1960's ->client server 1980'2 -> web -> cloud 2010
- frictionless : users vs IT provider conflicts
- efficient pooling : on demand self managed virtual infrastructure - consumed as a service
- cost drivers (17cents/hr ->6 cents /hr based on increased utilisation but with automation can get down to 2 cents / hr) - capital cost vs utilisation (server workloads)- zero touch infrastructure - provisioning deployment management
- self service - agility with control - freedom of choice - open interoperability - between clouds : pick & port but need to keep SLA's
- elastic capacity on demand - burst when you want it - pay for service - cope with surges or sprints rather than build capability to cope with surges
- application mobility - legacy & new apps without jeopardising SLA : existing apps - new enterprise apps SaaS apps - Datacentres - Public infrastructure - IPad driving Prosumers - Gartner study 2008 for 2009 - Cloud was at No.14 a year later Cloud was at No.2 in 2009 for 2010 - whither this year ?
- multi tenancy - keeping them partitioned - automatic upgrades - pay as you go - real time
- platform cloud - layer of abstraction
- open standards based : private cloud (behind the firewall) : public : Cloud Types : PaaS - Software as a ServiceSaaS - Elastic Compute cloud or infrastructure as a service IaaS
- VM Ware's offering : to link private clouds inside with outside clouds : vShield for security VCenter vCloudDirector
2. Derek Laney salesforce - sale hype ! themes : - why can't my work life be like my home life wrt computing apps ?
- recapped mainframe 1960's ->client server 1980'2 -> web -> cloud 2010
- ie massive generational shift from client service to web focus eg citrix concur cisco SaaS / cloud twitter google facebook Azure amazon PaaS / social mobile trends facebook webex citrix twitter - why can't we do this collaboration as easily as we can do on FB Twitter
- cloud : multi tenancy - automatic upgrades - pay as you go - real time - similar technology available to SME's as large corporations
- security - uptime 98.9 % - ISO 15489 Pts 1 & 2
- chatter platform - development platform cloud infrastructure - build your own platforms eg mobile lectures / Avon Lady on Markbook (like being on Facebook)
- how can I make money out of the cloud - very transaction focus
- replace Lotus Notes - replaces orgs public websites - Japan Post (bank service)
- app exchange -(KC comment : but some debate as to how many are really going to make money out of apps & quality of many apps)
3. Kevin Withnall ILB Computing - local company ex VM ware customer - very practical focus - not so much sales spin - wants to escape complexity - some define cloud not software over the internet - he defines it as someone else's problem
- Case Study 1 : client new office - building new computer room - when exchange server failed : recovered data to google mail dropbox - - back ups via Amazon - using dumb terminals - rented out building and work from home
- Case Study 2 : cut costs by 90% - telstra extensions - phone servers
- Case Study 3 : adsl vpn - no one needed at office to do backup tapes of data - exchange server - dropbox google apps
Applications - Google Premier apps vs Gmail : 25Gb /user - Google docs calendar - collaborative editing like Wave (collaborating now exists in Google Docs)google.com/A
- Dropbox (vs box.net) ? can do sharing - secure - potential to delete data - replication of every document - get every version ever saved eg @driessen - Dropbox is like Twitter is evolving to what user wants
- Evernote - remember everything application - when ATO audited them (they scanned all mail coming into operation and into Evernote) - Apps for Iphone - photo whiteboard and save to Evernote
- Amazon S3 - storage (Dropbox uses S3) - Cloudfront sits on S3 - S3 has Wordpress plugins - Ec2 - lets you have a server image for initial booting on new disc which sort of does provisioning
- Ratspace - Traffic speed costs - subsell hosting onto customers
- Jungle discs - puts all yr stuff onto S3 or Ratspace - don't need to worry about tape drives - get every version of docs back 3 months - backs up hourly - tape can't do this
- Cassandra - system Facebook's written it -also used by Twitter - scaleability is no problem
Questions - Legacy apps - transition legacy apps - everything is unsupported ? plenty of customers with unsupported applications
- Need huge amounts of bandwidth - virtualization great for legacy apps
- Risk issues ? are we just moving the risks to somewhere elsewhere ? what if someone does the cable link through Singapore - cutting us from our servers in USA ?
- what about - no longer solely dependent upon 1 anchor point - links that most likely to fail - adsl router fails more likely
- VCP - Concur - reporting expense management - offline mode - can synchronise with online mode - built as though something will go wrong - building in business process continuity plan - even your own data centres have the same risk -
- Large servers - big pipes - NBN - future
- Next trend : Taking it to the cloud - in the pocket - mobile is the new trend - prosumer market - flash - doesn't run on IPads -
- cloud is a matrix and gets accessed via a matrix - facilitates telecomputing
- why SaaS ?
- Flash mob - no software - USA San Francisco ?
- Government clients - what's the strategy for government clients' specific needs - V Wrapper - this application must have this level of security - cannot be multitenanted - must be offshore or onshore - this applications are being met ?
- Abstracts databases into systems by virtualisation is possible
- Greatest security risk is the person -
- Problem internet access if it goes down - by having local copies - salesforce offline does exist - what happens if your pc dies - paper file dies
- business process continuity is needed across all platforms ?
- what if your cloud provider goes broke ?
- can't solve everything with cloud now - will it be better to do it on disk & keep - but what about keeping it up to date ?
- computing is a 1 year 3 year 5 year plan process - how is the best way to do it?
