We live in a hyper-connected, mobility-enabled world, one in which carriers must make drastic changes to how they do business if they are to survive and thrive in the future. Accordingly, great strides have been made over the last three years to prove the viability of Network Functions Virtualization (NFV). Many Proof of Concept (PoC) trials have proven that workloads can be migrated to virtual environments running on standard hardware, and there are even examples of carrier deployments using NFV. The next step is to determine how to make NFV work effectively so it will deliver on its promise. The issue is no longer whether a service can be deployed using NFV, but whether we can manage and secure that service in an NFV environment. In other words, the challenge now is to operationalize NFV. How can we ensure that NFV is ready for this challenge? Network appliances a... (more)

The Transition to Cloud Computing: What Does It Mean For You?

Cloud Computing on Ulitzer We are standing on the threshold of a new transition in information technology and communications; a radical departure from current practice that promises to bring us new levels of efficiency at a vastly reduced cost. Cloud computing is full of potential, bursting with opportunity and within our grasp. But, remember, that clouds always appear to be within our grasp and bursting clouds promise only one thing: rain! As with all radical transitions, it takes time for the various pieces to fall into place. Some of them are already in place; some of them hav... (more)

Testing the Cloud

Cloud computing has now passed the stage of hype to reality. More and more enterprises are realizing the benefits of remote hosting of IT services rather than local IT management, especially as managing and operating IT networks and services is not getting any easier. Managing IT networks requires a broad set of competencies in a growing number of technologies and products. It therefore makes sense that these competencies are centralized in larger data centers providing cloud services to a number of smaller enterprises for which IT is not a core competency. Larger data centers al... (more)

The Emergence of the Universal Appliance

In 1956, Malcolm McLean invented a shipping system that revolutionized cargo shipping forever, namely the container. The shipping container provides a standard, universal packing solution that can be used for transporting whatever you need to ship. Containers can be transported on trucks, trains or on ships, because they are of standard size. Containers are an example of a universal solution that revolutionized the shipping industry. Can the emergence of the standard PC server platform as a universal computing platform herald the proliferation of even more innovative dedicated n... (more)

Remote Testing: the Achilles Heel of Cloud Services

Cloud services provide a new and promising opportunity for Enterprises to address the growing complexity of IT. The availability of smartphones and the expectation of immediate and simple access to both private and company specific information on a global basis are driving demand for centralization of IT services and the related competence required to support these effectively. Cloud service providers have established the necessary competence and IT infrastructure to deliver on these demands, but there is one potential Achilles heel that can present a challenge; assuring cloud s...
