A recent survey by communications and enterprise IT service provider Tata Communications found that enterprise organizations with more than 500 employees saw tangible benefits to their cloud computing efforts. The survey results included 85 percent of the respondents saying that the cloud had lived up to the industry hype, while 23 percent said it had exceeded their expectations. According to the global survey, 83 percent of the enterprises felt they had experienced benefits they didn’t […]

The use of public cloud platforms as a deployment option for applications is often talked about in black and white terms such as ‘do we deploy to the cloud or keep the application on-premise?’ This is misleading, as many businesses assess the suitability of public cloud only for the most appropriate use cases and often this will be for supplementary resources. The cloud journey will take them to a pragmatic balance between the use of […]
Just as virtualisation has transformed data centre operations, the emergence of cloud computing represents a significant shift in the way IT operates applications today. Up until now, IT ops teams have been driven by a server-centric operations model, where the application itself played a secondary role. Cloud computing, on the other hand, is an application-centric operations model. As applications get more distributed, virtualised and pushed into the cloud, application developers and architects are faced with […]
Organizations are widely migrating to the cloud to gain competitive advantages around speed, agility and flexibility according to Symantec Corp’s recent Avoiding the Hidden Costs of Cloud 2013 Survey. In fact, more than 90 percent of all organizations are at least discussing cloud, up from 75 percent a year ago. Other key survey findings showed enterprises and SMBs are experiencing escalating costs tied to rogue cloud use, complex backup and recovery, and inefficient cloud storage. […]
Enterprises are beginning to change their buying behaviors based on the deployment speed, economics and customization that cloud-based technologies provide. Gartner cautions however that enterprises are far from abandoning their on-premise models and applications entirely for the cloud. Based on an analysis of the Gartner Hype Cycle for Cloud Computing, 2012, the best results are being attained by enterprises that focus on a very specific strategy and look to cloud-based technologies to accelerate their performance.

As the role of cloud computing is growing significantly in its ability to deliver business applications, many IT decision makers are facing challenges with their existing network infrastructure to support the migration of their business applications to the cloud. An international study by Cisco revealed that without the proper cloud migration strategy, more than one third (38 percent) of IT decision makers would rather get a root canal, dig a ditch, or do their own […]
CIOs are worried: cloud computing is being used as a way for businesses to dodge the IT department and get services delivered more quickly. But as well as giving the CIO sleepless nights, this attempt to side-step the IT department is causing additional cost and complexity along the way. I recently wrote about how cloud computing deployments are kicking off without the CIO’s knowledge, and only coming to light when sys admins put their expenses […]
The network is the weakest link in cloud computing as, without network access, staff are unable to connect to databases, e-mail or other applications. While the cloud can store company data and deliver applications without the overheads of dedicated in-house servers and other hardware, the third party hosting the data or applications is not usually responsible for the network links from the customer to its facilities. Companies must plan how they connect their corporate networks […]
As the second law of thermodynamics tells us, all things trend toward chaos and this is no less true with a virtual environment. Sprawl can have a real security impact, and it takes discipline and planning to control sprawl — discipline and planning that won’t occur without someone from the security team actively monitoring the problem and formulating strategies for how to address the issue. Virtualization has been one of the most rapidly and widely […]
Using the OSI network layer model as a basis, here’s how to derive a simplified three-layer model for SIP-based VoIP and corresponding threats and defenses. The resurgence of interest in VoIP to provide telephone services worldwide is often credited to the use of session initiation protocol (SIP) for signaling. Both residential and enterprise VoIP services are widely deployed. IP telephony may be used either to replace the primary telephone service or to provide additional telephone […]
