Jclouds
...
Component
...
Available
...
as
...
of
...
Camel
...
2.9
...
This
...
component
...
allows
...
interaction
...
with
...
cloud
...
provider
...
key-value
...
engines
...
(blobstores)
...
and
...
compute
...
services.
...
The
...
component
...
uses
...
...
which
...
is
...
a
...
library
...
that
...
provides
...
abstractions
...
for
...
blobstores
...
and
...
compute
...
services.
...
ComputeService
...
simplifies
...
the
...
task
...
of
...
managing
...
machines
...
in
...
the
...
cloud.
...
For
...
example,
...
you
...
can
...
use
...
ComputeService
...
to
...
start
...
5
...
machines
...
and
...
install
...
your
...
software
...
on
...
them.
...
BlobStore
...
simplifies
...
dealing
...
with
...
key-value
...
providers
...
such
...
as
...
Amazon
...
S3.
...
For
...
example,
...
BlobStore
...
can
...
give
...
you
...
a
...
simple
...
Map
...
view
...
of
...
a
...
container.
...
The
...
camel
...
jclouds
...
component
...
allows
...
you
...
to
...
use
...
both
...
abstractions,
...
as
...
it
...
specifes
...
two
...
types
...
of
...
endpoint
...
the
...
JcloudsBlobStoreEndpoint
...
and
...
the
...
JcloudsComputeEndpoint.
...
You
...
can
...
have
...
both
...
producers
...
and
...
consumers
...
on
...
a
...
blobstore
...
endpoint
...
but
...
you
...
can
...
only
...
have
...
producers
...
on
...
compute
...
endpoints.
...
Maven
...
users
...
will
...
need
...
to
...
add
...
the
...
following
...
dependency
...
to
...
their
...
pom.xml
...
for
...
this
...
component:

Configuring the component
The camel jclouds component will make use of multiple jclouds blobstores and compute services as long as they are passed to the component during initialization. The component accepts a list blobstores and compute services. Here is how it can be configured.

As

you

can

see

the

is

multiple

The

actual

will

be

used

by

each

is

specified

the

the

URI.
