Cloud APIs
- ... utilize on-demand premise
- ... automatize deployment
- ... build self-managed systems
API categories
Blind APIs
don't tell you their restrictions
Closed APIs
disallow open-source implementations
Open APIs
do whatever you want as long as you give attribution
What else is open?
API protocol
HTTP (REST), SOAP, XML-RPC, JSON-RPC...
API libraries
fog, cloudfiles, cloudservers, aws,...
However...
Vendor lock-in
- Each provider designed own API specification
- Switching between providers is much harder
- Remember Oracle/SAP/Windows?
Deltacloud API
- Open Source cross-cloud API
- deltacloud.apache.org
- https://api.deltacloud.org
Why another API?
- Makes provider-to-provider migration easy
- Open license (ASL), development and design
- Rock solid ABI (drivers)
- REST based thus programming language agnostic
Architecture
- HATEOAS, thus easy discoverable
- Multiple media types supported (XML, JSON, HTML)
- Programmed in Ruby (not Rails!)
- Easy to develop new drivers
Abstraction layer
- Realm
- Hardware profile
- Image
- =
- Instance
$ irb
>
> client = DeltaCloud.new('user', 'password', 'http://localhost:3001/api')
>
> client.create_instance('img1', :hardware_profile => 'm1-small')
>
> client.instances.last.stop!
Extended collections
- Firewalls
- Keys
- Storage Volumes
- Buckets
Provider support
- Computing
- Amazon EC2, Rackspace CloudServers, GoGrid, Terremark VCloud, Rimuhosting, VMWare VSphere, RHEV-M, IBM SBC, Eucalyptus, OpenNebula, OpenStack, Mock
- Storage
- Amazon S3, Rackspace CloudFiles, Azure Storage, Google Storage
$ irb
>
> client = DeltaCloud.new('user', 'password', 'http://localhost:3001/api')
>
> client.with_config(:driver => :rackspace) do |rack|
> instance = rack.create_instance('img1')
> instance.destroy!
> end
>
> client.with_config(:driver => :ec2) do |ec2|
> instance = ec2.create_instance('ami-1234')
> instance.destroy!
> end

This...can happen
and this is the result
Aeolus Project
Manage Your Cloud Deployments with Ease
Aeolus Project
- Released under ASL 2.0
- Support for multiple public/private cloud options
- Ability to create equivalent images across multiple cloud providers
- Ability to manage lifecycle/monitor instances across multiple clouds at the same time (cuts dependency on a single provider)
