AWS and Nephophobia*: never again! * fear of clouds Friday, November 18, 11 adfas

Friday, November 18, 11 You only pay while the servers are running. 

Pricing Tiers • $0.02/hr (micro) up to $2.97/hr (Cluster Compute Eight Extra Large) • Some focused on memory, some on CPU Friday, November 18, 11 windows is 25% to 33% more expensive reserved instances (pay it up front for discounted hourly rate) 

Small Instance Example (Reserved vs. On Demand) • $490.30 = $262.80 (up front) + 227.50 (full time run for the year) • $744.60 Friday, November 18, 11 it pays to know what you want. So, what are you paying for? You're paying for a power and access to shared hardware running in a virtual machine. Amazon calls this an 'instance.' 

Instance Pricing • On Demand • Reserve • Spot Friday, November 18, 11 spot (based on supply and demand) 

What is an “instance?” Friday, November 18, 11 Anyone built or builds there own desktop machines? What are your steps? ask for software installation steps. 1st thing? what next? 

AMI? • A template for a running computer • What should be on it? Software? Data? A kitchen sink? Friday, November 18, 11 Imagine if you could record the state of your machine at that moment in time. Now, imagine if you needed to set up a new machine in the exact same manner. That's what an AMI is. Its a template of the OS and software at a given time that can be used to start a new running instance. Remember, you're only charged while the instance is running. Make an image. Use it when you need it. There're good opinions on how configured your desktop should be. Should it have your mail client configured? Should it have all your photos and precious documents? From an enterprise stand point, should the image be setup with the application software set to a specific version? This is a good question that we'll revisit a little later in the talk. 

Regions and Zones Friday, November 18, 11 Amazon has different regions, us-east-1, us-west 1 and different availability zones within those regions. Regions are for close to your customer. Zones are independent of one another.
