DLS employee arms cross in server roomBefore engaging a consultant you need to understand and be comfortable with their philosophy and approach. At DLS, our goal is to become your trusted technology and business partner. Throughout your relationship with us, we contribute measurable value and help you make the most of your technology investment.Many technology consultants also act as vendors to their clients. They both recommend and sell hardware and software. At DLS we believe that ethical technology consulting should be free of any conflicts of interests. We believe that it is wrong for a vendor/consultant to become the “trusted adviser” to an organization, and then use that trust to sell a whole slew of goods and services that have been designed to generate profits. We stand to protect our customers interests by offering unbiased approach to technology solution and firmly believe that a consultant who is vendor- and manufacturer-neutral is likely to play a more integral role in achieving your long-term goals.

Business Continuity

Business Continuity

DLS Network Solutions is strategically equipped with the disciplines necessary to provide our clients comprehensive services from first response to full recovery. Many businesses find it extremely difficult to manage a cataclysmic event while still maintaining vital day-to-day I.T. functions. Our team operates as an extension of your I.T. staff, providing support and best practices. While fully redundant computing architectures may be justifiable for some critical systems, they are not practical for the majority of information systems:
    • Redundant, multi-site infrastructures exponentially increase the complexity of maintenance and systems continuity management, taxing IT resources and managerial staff.
    • These redundant systems can be prohibitively expensive, siphoning financial resources that could be better employed for core business continuity activities.
    • Mastering, developing, and maintaining the detailed processes and documentation required for an effective Disaster Recovery plan – and the regulations that may govern those requirements – is a daunting challenge for most business, and can distract staff from higher-value core business activities.
DLS Disaster Recovery experts work with our clients to maximize their recovery. Our team provides a large range of services necessary to cover the requirements of a successful outcome. Among those are:
    • Methodologies supporting implementation of technology capabilities in your data center, in our data centers, virtualized or in “the cloud”, or across a combination of these — whatever is most appropriate for your needs.
    • Subscription to a Business Continuity workspace, provisioned very rapidly in the event that you cannot access your primary work location.
    • Innovative virtual computing and storage infrastructure provisioned on demand to meet disaster recovery and production scalability requirements.
