The virtualized and multi-tenanted data center is at the heart of cloud computing and every cloud-based service. All the applications and services we retrieve or consume in the Cloud, eventually reside in some data center - presumably built according to cloud criteria, i.e. loosely-coupled, shared, virtualized resources, auto-provisioning, auto-scaling, elasticity and so on. The primary difference between traditional corporate data center and cloud computing data center is in scalability and … [Read more...]

Normally, cloud computing services and applications are delivered to users through an Internet connection. This is one of the pillars of cloud computing, making it distributed, accessible and affordable from wherever and, increasingly, via various wireless devices. But what about organizations that want something more than a "best effort" service delivery through the Internet? Well, obviously there are several alternatives, including managed networks, e.g. MPLS, ATM and, in the future, many … [Read more...]

Recently, I participated in a research study under the auspices of Eurescom, working with research colleagues from Telenor, PT Inovacao (Portugal Telecom - Innovation) and Orange Labs (France Telecom). Our objective was to analyse Cloud Computing as both a technology concept and service delivery model, especially from its networking perspective, and its implications for telcos in general. We studied the current and promising networking technologies used in the Cloud, internally and externally, … [Read more...]

Many enterprises are understandably reluctant in moving their core applications to the cloud, primarily due to security issues but also due, perhaps equally, to concerns of poor network performance. According to a recent report from the Yankee Group, many thought leaders, including Trend Micro, Cisco and CSL, say the issue of latency and poor performance is, at least temporarily, hindering the adoption of cloud computing. This is not surprising. Quality of service delivery in the Cloud is … [Read more...]
