4. Overview
•
What is the cloud really? APIs on Datacenters!
•
Why provisioning for the cloud?
•
APIs are awesome, but writing your own wrapper sucks
•
Why do you care? I can get a 32gb server for €49/mo...
•
Pkgcloud use cases & capabilities
•
Why did Rackspace hire my to work on this anyway?

7. What is the cloud anyway?
•
Datacenters & Applications with APIs
•
Infrastructure-as-a-service
• Compute, DNS, storage, load balancing, databases, email,
orchestration, & more, all highly available
•
On demand resource creation
•
“Web-scale”
•
If you build it, they will come

9. Provisioning for the cloud
•
On-Demand Environments
•
A/B Deployment
•
Integration with Orchestration
•
Continuous Integration/Continuous Deployment
•
DRY – Don‟t Repeat Yourself applies to infrastructure too!
• From dev (maybe using vagrant?) to production

11. Writing your own API wrapper sucks
•
But, but, require(„request‟) makes it so easy
•
Maintenance hell. Just add another feature…
•
It‟s cool, I can open-source my wrapper
•
Idiosyncrasies of the API
•
It‟s all about priorities
• Spend your time on stuff only you know: Your Product and Your App.

12. But, Dedicated Servers!

13. But Dedicated Servers are Cheap!
•
Limited capacity
•
Provisioning lead time
•
Not truly on demand
•
Shifts control away from the developer
•
$50/mo for cloud only gets you a 1-2gb server :S
•
Sometimes both is a winning strategy too

16. Why pkgcloud?
•
Single convention, multiple clouds
•
Uniform vocabulary
•
Abstract out peculiarities of individual providers and APIs
•
Node is great for command line tools too!

18. What is multi-cloud?
•
Current Providers:
• Amazon, Azure, Digital Ocean, Joyent, Openstack, Rackspace
•
Generalized models across providers
• i.e. every compute provider has:
client.createServer(options, function(err, server) { ... });
•
Code is mostly portable (options signature for example)
•

23. Why is Rackspace involved?
•
We created OpenStack, and then gave it away!
•
We‟re all about community
•
Developer Advocates for PHP, Java, .Net, golang, Ruby, Python, node.js
•
We already have core committers on jClouds, Fog, libcloud, among others
•
We‟d rather engage and interface with existing open-source communities
than try to fragment them

26. The Future
•
Need to add more implementations of providers within services (i.e. make them truly
multi-cloud)
•
Refactor Databases entirely
•
More services (queuing, autoscale, orchestration, email, etc)
•
Command Line tools (rossk!)
•

27. Takeaways
• Design for the cloud from the start
• Focus on work only you and your team can do; not writing
API wrappers
• Put more control in the hands of you and your developers
