Software-Defined Adaptive Security Using SDN Analytics and Automated Response for Securing Hybrid Cloud, Datacenter, and Branch

by Hari Krishnan

The threat landscape is getting more sophisticated with the rise of ransomware, web based malware, botnets and phishing emails resulting in significant financial loss and data breaches. Recent malware like WannaCry ransomware that used lateral movement shows the importance of ensuring proper segmentation both at the branch and datacenter to contain lateral spread and the need for a new analytics based approach to detect and respond to these zero-day attacks. Recent massive data breach at Equifax Is a reminder to organizations on the importance of patching and quickly closing security vulnerabilities to secure key data before an attacker can use the security gaps to steal personal information. Organizations continue to get breached despite investments in security. Clearly there are gaps in organization’s current security model for these attacks to happen.

Build or Buy Cloud Infrastructure?

by Nick Lippis

On August 17th, Cisco reported that revenue fell for a seventh straight quarter. IBM has experienced revenue decline for the past 21 quarters. HP has been broken into multiple businesses. Dell was brought private after it acquired EMC and VMware. All the while, Amazon, Google, and Microsoft’s cloud businesses have grown stronger and collectively invested $31.5 billion in 2016 on capital expenses and leases, up 22% from 2015. Bridges are being built to extend enterprise private cloud infrastructure to public thanks to a new crop of software-defined startups. When you start connecting the dots, what you see is an IT industry that is fundamentally changing. Corporate IT planners always speak with their budgets, which represent their ultimate power, and ever since ONUG began in 2012, those voices are speaking with increasing volume. Continue reading

Moving Towards an SD-WAN API

by Steve Woo

SD-WAN is the application of SDN principles to the WAN. SDN provided for the separation of the control plane from the data plane, with an open API between these two elements. There was strong focus on enabling the programmable control to come from a different solution than the provider of the data plane forwarding elements. Therefore initial expectations of an SD-WAN API might be for the same functionality.  However, just as the architectural principles have morphed to meet the requirements and realities of the WAN, so must the focus of the APIs.

Best Practices for Hybrid Cloud Connectivity

by Toshal Dudhwala

Cloud architectures allow automated, on-demand delivery of applications and services, flexibly deployed across large, cost-effective resource pools, whether on-premises or from service providers. The automation and delivery of on- demand services are driving previously unimagined business agility and a new generation of business applications and revenue opportunities. Organizations must often weigh the trade-offs of additional complexity and overhead of an on-premises private cloud, with the limited controls and compliance risks inherent with public cloud providers.  Continue reading

Simplification Will Accelerate Software-Defined Data Center Adoption

by Steven Shalita

Organizations are looking for ways to scale-out their data center network to meet the increasing demands of the business. The digital enterprise, fueled by new applications, hyper-growth of the Cloud, and adoption of hybrid IT are all driving dramatic change. In order for organizations to fully realize the potential of technology, they are looking to modernize their network and leverage the Cloud for increased agility, speed and consistency. This means new approaches and capabilities are required. Ideally, all aspects of a data center would be virtualized and available as a service. We’ve already seen this happen with the compute and storage layers. But this has not really happened for the network. Continue reading
