1. a tool for developing portable Cloud-applications which can consume
hardware and software resources offered by multiple Cloud providers;
2. a brokerage system to support the decision of Cloud service provider
selection at the deployment stage.
3. an open-source PaaS that can be easily deployable by service providers
and which can be customized and enhanced by service providers;
Application
Portability!

CLOUDLET AND CONNECTOR
Cloudlet:

Ensure language
independence
 protocol syntax and
semantic enforcements.
 RPC solution that abstracts
addressing
 stubs to Driver API and
proxies to Connector
Behavior: event-driven,
stateless
 Automated elasticity: no.
of Cloudlet instances
controlled by Container
 Programmable elasticity:
no. of containers
 Functionality do not
depend on no. instances


Connector:
Behavior: RPC
Interface defining the set
of events
to which the Cloudlet
should react
 Abstract the access to
Cloud resources



Driver API
 wraps the native API
 all resources of the same
type are exposed
with the same interface
 eg. HBase vs. Riak keyvalue store:
a matter of configuration.

HOW TO USE IT?
Write component-based application



Debug application on the desktop or on-premise server(s)



Within Eclipse
Use Personal Testbed Cluster using VirtualBox for the VMs
Deploy application in a Cloud



Languages: Java, Python, [Erlang, Node.js]
Communications through message passing
Respect the event-driven style of programming
Cloud Summer School, Almere

7/25/2013

Assisted by Cloud Agency and Broker (with SLAs) OR
Use Resource Allocator
Control the application

Control the life-cycle of the components (start/stop/replace)
