The Law of Two Feet
This talk is not about…
And it’s not about…
or
There are no sexy demos...
Finally, it’s not about…
THIS is what it’s about
There is nothing permanent except change

Compute
• Generally virtualization based– IAAS: build your VM and they’ll run it– PAAS: build your app and they’ll run it (on a VM)
• Several flavors across vendors– Web requests (in and out)– “Worker” requests (long running)– High-performance compute
• Local emulation
Compute SurveyCloud Compute Unit
Amazon Machine Image (AMI)
Web Role, Worker Role, VM Role
requests, scheduled tasks, task queues, backends
instance (deployed from source)
App (tabs, forms, links + objects)
web dyno, worker dyno, on-off admin processes
instances (application, database, utility)
CloudSites, CloudServers

Developer SupportCloud Development platform
Anything you want (it’s IaaS)
Anything
Java (and derivatives), Python (v. 2.5), Go
Java (Spring), Ruby (Rails / Sinatra), Node.js
Data-driven (workflow, approval process), Apex (Java-derivative), Java/Spring (vmForce)

Reach: Where
• The trinity of reach– Where are your users? – Where is your app?– Where is your data?
• Latency– Data and application co-location– Multiple data centers = multiple service points– Content Delivery Network (CDN)
• Availability– [Auto] scaling capabilities– Geo-distribution– Disaster recovery: Multiple data centers/providers
• Compliance

Reach: How
• Identity– Anonymous– Authenticated– Federated
• Connectivity options– B2B (“behind the firewall”)– Hybridization of on-premises and cloud assets– Geo-distribution

Value
• Cost Structure– “Freemium”– Metered service usage– Per application/per user– Subscription based
• Service Level Agreements– Generally none at the “Freemium” level– Usually some at the paid levels (generally
commensurate with the plan)
More to Think About!
• Management– Monitoring (automatic and manual)– Billing
• ComplianceSSAE 16 (SAS 70) PCI HIPAA FISMAISO 27001 SOX EU Data Protection Directive
• Other services– MapReduce (e.g., Hadoop)– BI in the cloud (e.g., Windows Azure Reporting Services)– E-mail (e.g., Sendgrid)– Payment services (e.g., Amazon DevPay)– Marketplaces (e.g., Windows Azure Marketplace)
So, are you here?
Or here?
Recipes for Success
If your CTO doesn’t have a cloud computing strategy, his or her replacement will.
- source unknown
• Don’t panic – it’s new to all of us• Don’t succumb to analysis paralysis• Start small– Low business impact storage– Non-critical applications
• Participate in your cloud’s technical community
