    6. 6. Towards a more accurate cost model:Servers • For a 3-5 year time frame, yes depreciated servers do have a real cost • Use Heavy Utilization Reserved Instances for Apples to Apples comparisons • Maintenance starts at 10%- don’t forget you software maintenance costs
    7. 7. Towards a more accurate cost model: • Utilization rarely exceeds 60%Storage • What about backups? • 3 Copies of your data in 3 different Datacenters
    8. 8. Towards a more accurate cost model: • Buying for capacity means wasteNetwork • There are administration costs and hardware costs for your network • Using more bandwidth gets less expensive in AWS
    9. 9. Towards a more accurate cost model: • Renting floor space is a waste of moneyEnvironment • With Colocation providers – you are buying less than a full rack • Datacenters were built for last decade’s equipment – prepare for upcharges
    10. 10. Towards a more accurate cost model: • Hardware requires specialty skillsets at premium ratesAdministration • Lack of automation options = more labor • 4X improvement in server to admin ratio going to AWS
