    • There are many providers and pricing modelsWe have over 10,000 prices
    • Example: a MySQL DatabaseAWS Relation Database Service (RDS)- Up-front reservation fee (optional)- CPU: $X/hour (based on instance type and cloud)- Storage: $X/GB/month- Transactions: $X/Millions of I/O ops- Provisioned IOPS: $X/IOPS/month (has other limitations)- Redundancy: double the CPU hourly rate- Data transfer: $X/GB (tiered across cloud)
    • There are different purchase options- On-Demand: fixed rate- Reserved: pay upfront, lower rate- Spot: Bid how much you would pay- Discounts and consolidated bills
    • AWS Reserved Instances up-front procurement to pay-per-use You have to specify: term (1/3 yr), utilization, availability zone, instance type and OS when buying a RIImage  taken  from  h"p://aws.typepad.com/aws/2011/12/reserved-­‐instance-­‐opJons-­‐for-­‐amazon-­‐ec2.html  
    • AWS Reserved Instances Marketplace Buy and sell reservations
    • AWS Spot Prices Bid for an instance, it’ll get switched on if bid >= spot price. You pay spot price, AWS sets it.h"p://www.cs.technion.ac.il/~ladypine/spotprice-­‐slides-­‐postmortem.pdf  
    • Prices change(feels like there’s a price war between providers)
    • What the heck?I just wanted a simple database PlanForCloud simplifies this
    • How much would it cost to deploy my systems on Cloud X?Would it be cheaper if I use deployment option X or Y?What happens to my costs if:-  my system grows?-  cloud provider changes prices?
    • IT managers Software Engs Consultants AccountantsUsers
    • How much would Pinterest or TripAdvisor cost to host on the cloud?  h"p://highscalability.com/blog/2012/11/1/cost-­‐analysis-­‐tripadvisor-­‐and-­‐pinterest-­‐costs-­‐on-­‐the-­‐aws-­‐clo.html    
    • How much would it cost to deploy System X on Cloud Y? e.g. TripAdvisor’s 700K requests/min system on the AWS US-East cloud
    • $1.7M/year
    • Would it be cheaper to use deployment option X or Y?e.g. reserved instances, different types of instances, different cloud providers…
    • $0.9M/year(using reserved instances) 1st month: $450K After: $38K/month
    • What happens to costs if system grows? e.g. start with 410TB of S3 storage, then grow by 25% every month
    • Currently: $39K/month1yr from now: $470K/month
