Kurzfassung
Enterprise IT operators derive three
main benefits from the adoption of cloud technology:
1.
Resource “arbitrage”
2.
Relatively small units for resource allocation
3.
Metered resources
In the financial world arbitrage involves the simultaneous negotiation of the same
instrument in different markets
with the goal of pro
fiting from price differences.
In a cloud
environment an IT operator has a choice of running workloads in different geographic
locations or from services delivered by a variety of providers.
In organizations using physical allocation,
a new server represents a
three
-
year
commitment or longer, and therefore budgeting and procurement are c
ommensurately
heavy processes.
Securing these services through an internal or external cloud provider
is potentially orders of magnitude faster.
Cloud
resources are delivered through a service model where the service’s performance
and cost are specified contractually thro
ugh a service level agreement.
This environment
encourages a data driven approach to resource management, allowing for much agile IT
p
rocesses than those seen under more traditional budgeting models.
Most cloud based applications today run in virtualized environments. A necessary
condition for realizing the benefits is a capability for moving workloads across machines.
These machines c
an be part of a private cloud or in a public cloud, and with relocating
workloads there is a need to move virtual machines within and across different clouds.
This capability is described in an Open Data Center Alliance (ODCA) usage model
document
. A tea m led by T - Systems Telekom Innovation Laboratories, the FZI research team from the University of Karlsruhe and supported by Intel Corporation carried out a proof of concept (PoC) project to implement the usages described in the document, described in this report.
In context of the ODCA VM Interoperability Usage Model mentioned, an initial selection
was made of commonly found products in the corporate cloud environment, and a set of
appropriate experiments defined to test
them against the Usage Model.
The results
shown in this document demonstrate how closely these potential systems aligned to the
Usage Model at the time of the PoC tests towards demonstrat
ing Cloud technology
maturity.
Later iterations of testing may expand the scope of products as far
as practical
for a PoC test, an
d as software versions evolve.
Therefore the results shown represent a
minimum
suggested
baseline for cloud expectations and current cloud technology state
-
of
-
the
-
art, which should significantly improve for every subsequent t
est which the reader
may wish to initiate.
