Cloud Computing: In the WAN, it’s better to be single than attached

Grazed from NetworkWorld.  Author: Khalid Raza.

In a traditional WAN infrastructure, the control plane and data plane are tightly coupled, typically congruent, and cannot be separated due to how they are integrated with each network device. This architecture served the networking needs of enterprises well until now, since most data flows were structured around data centers with centralized exits.
 
However, the emergence of cloud computing and new dynamic business requirements that involve communicating with multiple partners and suppliers have forced enterprises to embrace new connectivity models. Today, enterprises need secure access to both partners and cloud provider infrastructures. This new model requires a different policy structure that is very difficult to instantiate and maintain within a legacy MPLS WAN...

Aryaka Launches the First Fully Integrated Cloud-Based SD-WAN, With Built-In WAN Optimization and Cloud Acceleration

Grazed from Aryaka.

Aryaka, the Software Defined Network Platform provider, announced today the launch of its SD-WAN ULTRA service at the NFV&SDN Expo in Fort Lauderdale. Aryaka has built the first fully integrated SD-WAN solution that combines a global private network, WAN Optimization and cloud/SaaS acceleration to deliver enhanced application performance, reduce capital expenditures and simplify network operations at branch offices.

With these components, Aryaka's SD-WAN ULTRA addresses the Achilles' heel of SD-WAN solutions -- inconsistent latencies and jitter, associated with their dependence on the public Internet for transport of mission-critical voice, video, data and application traffic that is vital to business execution. The public Internet is a shared medium of communication, and due to congestion and packet loss, lacks the performance required for transferring business-critical voice, video and data, and accessing cloud services or SaaS applications globally.

How to optimise hybrid cloud by extending the enterprise WAN to IaaS

Grazed from CSO. Author: Brian Grant.

Infrastructure-as-a-Service (IaaS) in the enterprise is expected to grow at a rate of 37.3 per cent through to 2017, and is the fastest growing segment of the infrastructure service domain, according to Gartner 1and 2. The trend is supported by ESG’s 2014 Public Cloud Computing Trends report, which discloses that 47 per cent) of organisations with more than 500 production servers are already using infrastructure-as-a-service, compared to 23 per cent of those with fewer than 50 production servers.

So for larger enterprises, IaaS is no longer limited to ‘skunkworks’ proofs-of-concept (POCs). Hard contractual obligations, balance sheet objectives and increased complexity in hosting critical applications are driving IT to scale some processes off corporate premises towards a hybrid cloud model...

Silver Peak Sets Sights on New Enterprise Network: Unifies Cloud, Internet, and WAN on Single Fabric

Grazed from Silver Peak.  Author: PR Announcement
 

Silver Peak today unveiled Unity, a groundbreaking intelligent wide area network (WAN) fabric that unifies the enterprise network with the public cloud. Unlike traditional WAN optimization solutions, Unity correlates information about cloud services and Internet “weather” to intelligently route traffic over a secure, optimal path. By keeping SaaS and IaaS traffic on the Unity fabric, IT gains an ability it’s never had: the ability to monitor and control connectivity to the cloud while ensuring consistent SaaS performance.

"Most enterprises use dozens of SaaS services, whether IT knows about them or not," said David Hughes, CEO of Silver Peak. "That usage will only increase as enterprises shift computing workloads to the cloud. The problem is, IT staff have no insight into that traffic once it leaves the WAN. They can't troubleshoot problems or optimize applications the way they would on their own network. CIOs don't want to be responsible for performance they can't control."

Cloud Computing: Next-Gen WAN - Build or Buy?

Grazed from NetworkComputing. Author: Mitch Simcoe.

Enterprises today need WAN connectivity that can support their growing cloud and virtualization efforts. There are two main business models to choose from: A build-your-own network model based on dark fiber and the use of carrier-grade packet-optical technology, or a managed private network service that is outsourced to a service provider.

To decide which option to pursue, enterprises must carefully analyze the two deployment models against a well-defined list of capabilities that can best address their company’s long-term goals and needs. They also need to establish clear objectives for how to allocate operational and capital expenses for these initiatives going forward. In the final analysis, this may not be an either/or decision as many organizations have both models running concurrently. Here are some key factors to consider when weighing your options:...

The cloud is enabling the Next-generation Enterprise WAN, and vice versa

Grazed from NetworkWorld. Author: Andy Gottlieb.

Having spent the last several columns looking in depth into why MPLS is no longer the only answer for building enterprise WANs, this time let's go up a few thousand feet and look at the bigger picture, before any further dives down into the details.

"The cloud" is happening. We'll leave aside for the moment exactly what "the cloud" means, as it tends to mean different things to different people, but I think readers here have at least a "kinda sorta" understanding of what it is. As it relates to wide area networks and enterprise IT, let's go for now with Gartner's definition of cloud "as a style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service using Internet technologies."...

How to leverage WAN optimisation for high-performance cloud services

Grazed from IT Pro Portal. Author: Keao Caindec.

Cost savings, convenience, speed-to-market and freedom from technology lock-ins are all benefits of migrating business applications to the cloud, and many that have already adopted cloud strategies have indeed realised significant cost savings and productivity gains. However, some have also experienced performance and availability issues that have led to resistance to migrating business-critical functions. As a result, the bulk of successful cloud projects to date have been departmental and not ‘mission critical’ core systems which have significant requirements for resource-intensive functions such as database replication, file synchronisation, backup and disaster recovery between data centres.

Part of the problem is that the public cloud ‘Infrastructure as a Service’ (IaaS) market is evolving more slowly than other areas such as ‘Software as a Service’ (SaaS). Providers are only beginning to recognise the level to which performance levels need to be increased and the capabilities their offerings need to make them a viable platform for mission critical purposes.
One area of IaaS that providers have quickly evolved is services that support wide area networks (WAN)...
