This document provides an introduction to Apache jclouds, an open source toolkit that allows Java applications to access multiple cloud infrastructures through a unified API. It discusses key jclouds concepts like providers, views, and portability. Examples show how to connect to clouds like OpenStack and Rackspace, retrieve API resources, and make cloud-specific calls in a portable way. Community involvement and the jclouds roadmap are also summarized.

56. jclouds
Apache jclouds is an open source
multi-cloud toolkit for the Java
platform that gives you the freedom to
create applications that are portable
across clouds while giving you full
control to use cloud-specific features.

72. Code
Context
1 NovaApi novaApi = ContextBuilder.newBuilder("openstack-nova")
Defaults
Top Level API
2 .credentials("myUsername", "myPassword")
3 .endpoint("http://myOpenStack.com:5000/v2.0/")
4 .buildApi(NovaApi.class);
Resource API
5 ServerApi serverApi = novaApi.getServerApi("region");
6 ServerCreated server = serverApi.create("serverName", "imageId", "flavorId");
Resource Web Service Call (cloud-specific)

73. Concept
Provider

74. Code
1 NovaApi novaApi = ContextBuilder.newBuilder("rackspace-cloudservers-us”)
2 .credentials("myUsername", "myPassword")
3 .buildApi(NovaApi.class);
4 ServerApi serverApi = novaApi.getServerApi("region");
Provider:
• Endpoint
• Overrides
• Configuration
5 ServerCreated server = serverApi.create("serverName", "imageId", "flavorId");

75. Concept
Portable Abstraction (View)

76. Code
1 ComputeServiceContext context = ContextBuilder.newBuilder("rack-cs-us")
2 .credentials("myUsername", "myPassword")

4 ComputeService computeService = context.getComputeService();
Portable Abstraction (View)

77. Code
1 Template template = computeService.templateBuilder()
2 .locationId("locationId")
3 .osFamily(OsFamily.UBUNTU)
4 .minRam(2048)
5 .options(inboundPorts(22, 80))
