http://www.ttec.nl/en/company/references Your IT has grown along with your company and thus has be-
come more complex. Confidential and company-critical data are
distributed over different storage devices and even at different
storage locations, whereby the clarity and security suffer as a
result and the management has to commit more resources. As
a result of the constantly changing technologies, parts of your
infrastructure are not current anymore, are not adequate to
your performance needs and require increased attention. You
must ensure a 24x7 mode of operation. That is why you would
like to invest in a future-proof and flexible solution in order to be
equipped in the long term for any circumstances.
