Datalink Showcases Secure Hybrid Cloud Solution at Cisco Live 2016

Grazed from Datalink

Today at Cisco Live, Cisco's annual IT and communications conference, Datalink (DTLK) announced the addition of secure hybrid cloud capabilities to its all-in-one Cloud Complete package of services and solutions for fast-tracking IT transformation and associated cloud deployments. Cloud Complete bundles strategic planning, design and security services with both converged and hyperconverged infrastructures, private and hybrid cloud build-out, and technical support, creating a project framework that shortens cloud rollouts from months to weeks.

The new Cloud Complete security enhancement enables security policies to be defined within the hybrid cloud environment at the application level, based on an analysis of client workloads by Datalink consultants. The resulting microsegmentation - achieved through the software-defined network (SDN) features of the Cisco Application Centric Infrastructure (ACI)- makes it possible to segregate sensitive information such as billing and customer data to mitigate the risk that a hacker traversing the network laterally will be able to gain access to the most privileged accounts.

Cloud Computing: VMware President Carl Eschenbach Says the Software-Defined Data Center Is the Future

Grazed from BizTech. Author: Ricky Riberio.

The technology that companies use is changing at a blistering pace. While companies are still considering whether or not to virtualize their servers, other enterprises are planning on turning their entire infrastructure into a software-defined machine. The software-defined enterprise starts, first and foremost, with fundamental architectural shift we are seeing in the industry.

And that is the movement to a software-defined data center. And that software-defined data center can be delivered on-premise or off-premise, known in the world as hybrid cloud computing. That's where the world is going," said VMware President and COO Carl Eschenbach. Eschenbach was one of several IT leaders who gathered to discuss the most important and needle-moving technology challenges facing businesses today, as part of CDW’s Bring IT On technology leadership series...

Cloud Computing: UK firms struggle to grasp software defined networking

Grazed from CBROnline. Author: Editorial Staff.

Nearly half of UK organisations are ready to adopt software defined networking (SDN) even though they don't understand it. A survey of 200 IT decision makers found that 40% of businesses are planning to deploy SDN, which promises to make the network more flexible, easier to manage and more secure, within the next five years.

Another 34% said they are planning to adopt Network Functions Virtualisation (NFV) during the same period, with 27% keen to do so before 2018. However, 37% of decision makers admitted that they did not fully understand the concept of SDN, while 45% said the same about NFV...

The Dynamic Cloud Needs the Software Defined WAN

Grazed from EnterpriseNetworkingPlanet.  Author: Arthur Cole.

Software defined networking (SDN) is the last step toward creating the fully virtual data center. In the age of the cloud and Big Data, however, a single data center is no longer enough for most organizations.  What they need is a virtual, multisite data ecosystem that can be parsed into very finite instances or harnessed into massive computing environments.  But to do that, the enterprise needs to start pushing SDN over the wide area network (WAN).

The need for the software defined WAN

The subject was front and center at the most recent gathering of the Open Network User Group (ONUG), where, according to IT Connection’s Mike Fratto, the general consensus was that the telecom service provider market has been too slow in the uptake of dynamic WAN connectivity...

Cloud Computing: Software-Defined Networking's 3 Biggest Benefits

Grazed from InformationWeek. Author: Bill Kleyman.

SDN may sound abstract, but the technology is on target to provide concrete advantages to network infrastructure -- from increased global connectivity to better content delivery. The concept of the software-defined network (SDN) initially caused some confusion in IT, but the picture gets clearer the more we learn. Similar to network virtualization, SDN allows for the direct network-related abstraction of services.

This abstraction of services can be accomplished on both logical as well as physical infrastructures, but is not actually defined by specific physical devices or logical components. How will SDN affect the future of network infrastructure? Let's take a look at the biggest benefits...

Creating Cloud Optimization with Network Intelligence

Grazed from DataCenterKnowledge. Author: Bill Kleyman.

The direct proliferation of cloud computing has resulted in a huge boom in traffic over the WAN. There are more users connecting, a lot more data points, and the modern data center sits right in the middle. Throughout this entire cloud evolution – the infrastructure was forced to change as well. Edge and core routing needed to evolve to handle this influx of traffic and new content.

Service providers as well as enterprises deploying demanding, mission-critical applications are facing unique networking challenges. Here’s part of the issue: Network administrators are trying to deal with new types of cloud growth issues by adding additional providers, creating and applying routing policies in reaction to situations, and rerouting the traffic manually...

Cloud Computing: SDN Will Move Mainstream - Juniper Networks

Grazed from CRN. Author: Ashish Dhawan.

2013 saw the elevation of cloud computing as fundamental to business strategy. IT leaders now need to rethink the role of the network to deliver on the promise of the cloud. As enterprises begin to realize the benefits of the cloud, and as deployment and orchestration systems such as OpenStack and CloudStack mature, managing data centers will be about managing cloud workflows.

Both enterprises and service providers are looking to the cloud to help them move their businesses forward. For enterprises the cloud makes workloads and applications more dynamic, but before they can take advantage of this benefit they need an infrastructure which is optimized for private and public cloud services. Service providers, be they the traditional network service providers or cloud service providers, need a quick way to deliver new services and improve the time-to-revenue...

Cloud Computing: Software-Defined Networking Rises Above The Hype

Grazed from InformationWeek.  Author: Daniel P. Kent.

Over the last year, we've seen another technology phenomenon added to the long list of IT hype: software-defined networking (SDN). You might ask: "Haven't networks been defined by software since the days of the ATM or the introduction of VLANs?" The answer is yes, there have been efforts to manage and manipulate physical network components through software, but most of these efforts have focused on easing network management tasks.

What makes SDN different is its intent to allow programmability of the network based on real-time information and data traffic flows. This allows for a closed-loop system where the network can be reconfigured to optimize applications or protect against threats dynamically, based on the current environment...
