Clouds Are Cool So Why Arent We Using Them Yet[1]

  1. 1. Clouds are cool <ul><li>(So why aren’t we using them yet?) </li></ul><ul><li>Rhys Jones </li></ul>
  2. 2. <ul><li>What we do today & why </li></ul><ul><li>Why clouds are interesting </li></ul><ul><li>Why we aren’t using them (yet) </li></ul><ul><li>Where are we going </li></ul>
  3. 3. We own our own data centres <ul><li>They are where we need them globally </li></ul><ul><li>Tailored to our needs </li></ul><ul><li>Secure </li></ul><ul><li>Someone internal is accountable </li></ul><ul><li>We’ve been doing this for years </li></ul>
  4. 4. Standardise & Centralise <ul><li>Control costs </li></ul><ul><li>Small number of engineered platforms </li></ul><ul><li>Small number of skilled resources </li></ul><ul><li>Complexity and diversity are the enemy! </li></ul>
  5. 5. Focus on “sweating the assets” <ul><li>We have already bought the servers </li></ul><ul><li>Increased utilisation means lower additional spend on new servers </li></ul><ul><li>Shared compute grids </li></ul><ul><li>Cycle scavenging </li></ul><ul><li>Virtualisation </li></ul><ul><li>SaaS </li></ul>
  6. 6. Why do we do this? <ul><li>Avoid diversity which drives up costs & reduces quality </li></ul><ul><li>Makes best use of (scarce) resources </li></ul><ul><li>Data Centres are expensive! </li></ul><ul><li>Long planning horizons </li></ul>
  7. 7. Power is nothing without control <ul><li>Centralised controls </li></ul><ul><li>Mostly on capex </li></ul><ul><li>Manage supply side </li></ul><ul><li>Reduce complexity at source </li></ul><ul><li>Top down targets </li></ul><ul><li>Just one more server could cost a thousand or 10 million or more </li></ul>
  8. 8. What are the consequences? <ul><li>Some compromises for app dev teams </li></ul><ul><li>Hard to change direction </li></ul><ul><li>Lead time = planning required! </li></ul><ul><li>Sharing has to be planned </li></ul><ul><li>Under the radar demand </li></ul>
  9. 9. So why are clouds interesting? <ul><li>Switch from capex to opex </li></ul><ul><li>Optimisation is automatic </li></ul><ul><li>Allows us to do things we couldn’t do before </li></ul>
  10. 10. Why is opex preferable to capex? <ul><li>Pay for what you use </li></ul><ul><li>Flexibility and transparency </li></ul><ul><li>Can scale down as well as up! </li></ul><ul><li>Less lumpy </li></ul><ul><li>No new Data Centres to plan! </li></ul>
  11. 11. Optimisation is automatic <ul><li>No longer have to negotiate between teams </li></ul><ul><li>Utilisation is someone else’s problem </li></ul><ul><li>But thats how the vendor makes the service cost effective </li></ul><ul><li>Requires a switch from managing supply to managing demand (which is infinite) </li></ul>
  12. 12. It’s not just box rental <ul><li>We already do that </li></ul><ul><li>Front to back capacity on demand </li></ul><ul><li>SaaS in combination is key </li></ul><ul><ul><li>AWS shows the way </li></ul></ul><ul><li>Need central control as well as project level flex </li></ul><ul><li>but requires “big thinking up front” </li></ul>
  13. 13. Allows us to do things we couldn’t do before <ul><li>Rapid low-risk trials or prototypes </li></ul><ul><li>Short term projects </li></ul><ul><li>Nice to have projects </li></ul><ul><li>Bypass controls (gasp) </li></ul><ul><li>Things we hadn’t planned! </li></ul><ul><li>But... </li></ul>
  14. 14. There are some gaps in the current cloud offerings <ul><li>SLAs </li></ul><ul><li>Security </li></ul><ul><li>Global coverage </li></ul><ul><li>Patterns & best practice </li></ul><ul><li>Interoperability </li></ul><ul><li>Vendor long term viability </li></ul>
  15. 15. What are the other reasons? <ul><li>Organisational and cultural change is required and that is hard </li></ul><ul><li>Control processes don’t translate </li></ul><ul><li>Rethinking everything about how you operate is a big job </li></ul><ul><li>Diversity is still the enemy </li></ul><ul><li>Who do you fire when it goes wrong? </li></ul>
  16. 16. Control processes are a major issue <ul><li>Demand always outstrips supply </li></ul><ul><li>Tightening the controls reduces the flexibility </li></ul><ul><li>Centalised vs federated </li></ul><ul><li>Teamwork does not scale! </li></ul><ul><li>Current controls make it hard to even start using clouds </li></ul>
  17. 17. Enterprises will need new operating models <ul><li>Build a business case for cloud usage </li></ul><ul><li>Design new controls </li></ul><ul><li>Design the supporting infrastructure </li></ul><ul><li>Take the risk </li></ul><ul><li>Who will do this? </li></ul>
  18. 18. Vendors will have to provide more as a community <ul><li>The big thinking up front needs to be done by someone </li></ul><ul><li>Its in the best interests of the cloud vendor community to do it </li></ul><ul><li>Multi-vendor solutions are required today </li></ul><ul><li>A major infrastructure player could clean up if they did this </li></ul>
  19. 19. How will things evolve? <ul><li>Continue on the internal optimisation path (0.9) </li></ul><ul><li>Increased use of SaaS for non-critical apps (0.7) </li></ul><ul><li>Internal clouds are unlikely (0.7) </li></ul><ul><li>Come to us with all the answers and we’ll be interested! (0.8) </li></ul>
  20. 20. Summary <ul><li>We already do things that get us part way to the benefits of clouds </li></ul><ul><li>Clouds have service gaps that need to be addressed </li></ul><ul><li>Organisational and cultural change is the real obstacle </li></ul><ul><li>Predictions are hard, especially about the future </li></ul>
