No Cloud is an Island

  1. 1. NO CLOUDIS AN ISLANDHybrid clouds offer new revenue opportunitiesBy Jelle Frank van der Zwet & Ian Murphy@interxion
  2. 2. INTRODUCTIONBusiness computing stands at a crossroads.There is no more tolerance for the costly, under-delivering, grand IT projects of the past.2 No Cloud is an Island
  3. 3. INTRODUCTIONCompanies increasingly look at cloud-basedtechnologies as a means of delivering the nextgeneration of IT via a low cost, dynamic and flexibleresource platform.3 No Cloud is an Island
  4. 4. INTRODUCTIONBut not every application will go into the cloud. Corebusiness-critical systems will stay in-house, whileless sensitive systems are ideal candidates for clouddeployment.This presentation proves that cloud and on-premisesystems can work together.4 No Cloud is an Island
  5. 5. INTRODUCTIONWe want to lay down some straight-forward advice and steps on how thiscan be achieved.That’s what this presentation delivers.5 No Cloud is an Island
  6. 6. INTRODUCTIONThe challenges addressed are: UNDERSTANDING THE CLOUD• A world of many clouds• Cloud deployment models• Why cloud appeals to your customers WHY HYBRID?• Better fiscal management• Adopting a hybrid cloud THE LOGICAL HOME FOR YOUR CLOUD• Challenges known• Challenges new6 No Cloud is an Island
  7. 7. UNDERSTANDINGTHE CLOUDNo Cloud is an Island7
  8. 8. A WORLD OF MANY CLOUDS• There are three key cloud models: private, public and hybrid, and market-focused versions such as community clouds that address specific marketsand groups.• A private cloud is where the resources are owned and accessed only by theenterprise, whereas the public cloud is a shared environment.• For some applications and organisations, there is a solid business casewhere core applications will be in a private cloud but some applications andfunctions exist in the public cloud.• This is known as the hybrid cloud.8 No Cloud is an Island
  9. 9. CLOUD DEPLOYMENT MODELS9 No Cloud is an Island
  10. 10. WHY CLOUD APPEALS TO YOUR CUSTOMERSCloud offers a range of benefits to both large and small enterprises10 No Cloud is an IslandLarge Small• Efficiency: ability to manage budgets, ITmaintenance and upgrade programmes moreefficiently. This is because cloud computingoffers flexible access to IT resources, skills,new technologies and the latest updates andpatches for servers, tools and applications.All this without the management, licensing andpurchasing headache this would normallyinvolve.• New Access: cloud computing levels thetechnology playing field. Access to resourcesand technologies beyond anything their usualbudgets could afford enables them to take theirbusiness to the next level.Importantly, they gain access to the people andprocesses that can help create competitiveadvantage from these new technologies.
  11. 11. WHYHYBRID?No Cloud is an Island11
  12. 12. WHY HYBRID?• The key challenges for all sizes of business are creating the private cloudand then integrating it with their chosen public cloud.• Correctly configured, the hybrid cloud offers many benefits. ImprovedSLAs, the ability to scale an application out to hundreds of servers, theability to do very specific types of computing, such as big data orapplication testing.12 No Cloud is an Island
  13. 13. BETTER FISCAL MANAGEMENTThe most important benefit of hybrid cloud is cost reduction and better fiscalmanagement of IT. This benefit can be realized in several ways:• Reduced capital expenditure on new hardware and software• Reduced running costs on data centre power and cooling• Higher utilisation of resources which in turn lowers the cost of providing IT•• Metering which allows application usage to be more effectively costed• Faster and more cost-effective access to new applications throughSoftware as a Service (SaaS)• Ability to deploy new solutions more quickly13 No Cloud is an Island
  14. 14. WHY HYBRID?14 No Cloud is an Island
  15. 15. ADOPTING A HYBRID CLOUDEnterprises will pick and choose applications and vendors based on theirbusiness needs, thus creating a diverse and heterogeneous cloudenvironment.Examples of hybrid cloud adoption today are:• Corporate websites are moving to the public cloud to improve access andreduce the risk of downtime.• Online web stores are using the public cloud for their catalogue andtransferring customers to the private cloud to complete payment options.The public cloud allows for the quick provisioning of resources when apromotion takes place while the private cloud enables the securing ofcustomer data.15 No Cloud is an Island
  16. 16. CHALLENGESKNOWN AND NEWNo Cloud is an Island16
  17. 17. CHALLENGES KNOWNChallenge DescriptionInfrastructure and Virtualisation Hardware is increasingly power-efficient. Although prices havefallen, it can still be expensive. The recession has seen a largeamount of hardware, often less than 3 years old, on the qualitysecond hand marketSoftware and Services The challenge is creating an automated and controlledenvironment with proper management and governance toolsSecurity You may be sharing hardware and even services across multipleclients, so there is a need to ensure the physical and logicaldesigns are secureThe importance of partners Choosing the right partner is important because they will havelease programmes for hardware and software and will work withyou on resolving issues such as software licensing17 No Cloud is an Island
  18. 18. CHALLENGES NEWCloud infrastructure requires aFastDedicatedScalableEfficientResilientnetwork18 No Cloud is an Island
  19. 19. CHALLENGES NEWChallenge DescriptionFast Cloud-based solutions can take advantage of very high speed interconnectsthat would be very expensive to provision direct to a company office.Dedicated Direct links between the cloud and the customer guarantees performance, andimproves security by removing the public Internet riskScalable All applications have traffic peaks which can sometimes be managed throughthe Quality of Service mechanisms.Efficient QoS and traffic shaping help manage network traffic - important for mission-critical applications that need guaranteed bandwidth at busy times.Resilient Multiple network circuits into both the data centre and the customer providescalability and business continuity.19 No Cloud is an Island
  20. 20. NETWORK SECURITY• Traditional solutions rely on firewalls for protection.• Recognising the speed with which VMs are created and deployed, vendorshave created rule-based virtual firewalls that can be kept constantlyupdated and deployed on demand.• The key here is ‘constantly updated’. Now, there are vendors that allow fora master firewall to update the elements of all firewalls, even those inshutdown VMs.20 No Cloud is an Island
  21. 21. ASSESSINGRETURN ON INVESTMENTNo Cloud is an Island21
  22. 22. ASSESSING ROI The real ROI for cloud is about the costs that it would take to deliver thesame level of service internally. This includes hard and soft metrics such as uptime, user experience, costof hardware / software, integration, cost of bandwidth, data centre powerand cooling costs, and staff costs22 No Cloud is an Island
  23. 23. ASSESSING ROI23 No Cloud is an IslandBusiness Case Cloud PremiumReducing the cost ofdevelopment and testingenvironments• The speed with which a testing environment can be provisioned• Ability to do more intensive and extensive testing of applications• Access to high value test tools on demand via SaaS• Access to test professionals in different locationsScalability • Ease of adding additional compute, network and/or storageresources• Ability to shrink resource pool when not requiredCompetitive advantage • Faster time-to-market for new applications and solutions meansnew market opportunities can be quickly explored• Speed of identification of trends and designing competitivesolutions• Lower cost of IT releasing more money for other parts of thebusiness
