  • I going to be talking about private and public cloud computing and the experience we’ve had with voice in SA
  • - Talk about Chris Pinkham developing the Amazon EC2 cloud here in Diep River and the new Nimbula - If only 4% don’t have private cloud plans one has to be adapting their solutions for this change
  • Unified communications in the private and public Cloud - by Rob Lith

    1. 1. Rob Lith Unified communications in the private and public Cloud
    2. 2. PRIVATE OR PUBLIC Private Cloud Public Cloud Enterprise Cloud Hosted Services Voice Voice Voice Voice
    3. 3. PRIVATE OR PUBLIC On-Net <ul><li>There is a bit of debate on what is cloud computing </li></ul><ul><li>So long as it’s scalable and abstracts management away from the user I’d call it cloud computing </li></ul><ul><li>To me public open clouds, secured private in public data centres clouds and on-premise customer owned clouds, all fit the bill </li></ul><ul><li>It should be what suits you best for your requirements – where you or your customer is comfortable starting </li></ul><ul><li>But the technology that brings scalable, flexible, and costs effective solutions can not be ignored </li></ul>
    4. 4. BUSINESS CASE On-Net <ul><li>Unless the costs and benefits outweigh the status quo there is no compelling reason to move to the cloud! </li></ul><ul><li>Benefits alone will not drive this innovation </li></ul><ul><li>If the NPV cost of a cloud solution over a reasonable period, say three years, is not less than an equivalent capital purchase, the business case starts failing in the customers eyes – before and after scenarios are critical </li></ul>
    5. 5. OPPORTUNITY? On-Net <ul><li>According to Roelof Botha at Sequoia Capital, “Cloud computing is a game changing market opportunity” - Sequoia and VMware have invested in Nimbula founded by the team that developed Amazons EC2 (elastic cloud computing) </li></ul><ul><li>A recent Gartner poll showed that by 2012 IT organizations will spend more on private clouds than public clouds. Only 4% of those polled didn't have private cloud plans </li></ul>
    6. 6. BANDWIDTH BOOM On-Net <ul><li>Within 18 months, SA will experience a broadband and communications boom not witnessed since the Internet growth years of the 1990s - Ermano Quartero </li></ul><ul><li>Quartero says investments in fibre are already resulting in more companies — including big corporate entities — deploying mission-critical business applications in the cloud </li></ul><ul><ul><li>— Duncan McLeod, TechCentral, 27 August 2010 </li></ul></ul>
    7. 7. WHAT NEXT On-Net <ul><li>So where to for voice in the cloud </li></ul><ul><li>The cloud is our turf </li></ul><ul><li>The business case is compelling </li></ul><ul><li>The opportunity is here </li></ul><ul><li>The bandwidth boom is coming </li></ul><ul><li>But….are there dark clouds ahead? </li></ul>
    8. 9. OUR TURF THE CLOUD On-Net <ul><li>Is it going to voice as usual?? </li></ul><ul><li>Remember the snake with the twirly eyes in the Jungle Book? ”Trussst in me” </li></ul><ul><li>Old world telcos want us on their turf – to trussst them and do everything by the minute by the second </li></ul><ul><li>for now we have to call to and from the traditional PSTN … </li></ul><ul><li>but when we work with each other, lets do it the Internet way </li></ul>
    9. 10. C IP 10% BRING IT DOWN TO IP Public Cloud My Cloud Your Cloud GSM 60% PSTN 30% On-Net Last Mile Access Multiple Termination Telecoms Spend
    10. 11. VOICESA On-Net <ul><li>Still, I suppose it would be convenient to be able to call between their world and ours… </li></ul><ul><li>(They do support at least basic voice) </li></ul><ul><li>For now that is… </li></ul>
