SDN is not just today's fad or buzzword. SDN is a new, dynamic network architecture that transforms traditional network backbones into more intelligent service-delivery platforms. IT leaders can use SDN as a tool to change the way they do business. For example, enterprises can foster closer relationships with their customers by offering greater online access to select data over the enterprise network. A financial services firm can give large corporate customers the opportunity for third-party reporting, governance, or even allow analytics firms to directly access enterprise credit card transactions, obviating the need for intermediate sites and cumbersome manual process steps that are needed to provide sufficient multi-level security. An SDN would create virtual network partitions governed by stringent and limited access policies, and security to decrease unauthoriz... (more)

Software-Defined Networking: The Promise and the Reality

The enterprise is increasingly resorting to cloud services for many applications ranging from efficient application hosting or low-cost backup and archiving to cloud data centers. Typically, enterprise networks are interconnected to the Cloud over low speed IP networks that are limited in capacity and flexibility. Over the next few years, however, enterprises will leverage the cloud for larger amounts of storage as they adopt Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). This in turn compels the need for a more flexible and intelligent network capable of dynamically responding to rapidly changing IT demands, without bottlenecks, security vulnerabilities or data loss. The impact of the cloud necessitates that Enterprise IT provide more focus on server-server connectivity rather than primarily supporting client-server interactions. This shift... (more)

Building Vagrant Machines with Packer

Sharing a common development environment with everyone on your team is important. It is really hard though to keep the same dependencies, database versions and other systems in sync between different machines. Vagrant is a great tool that helps with this and manage the lifecycle of a virtual machine. As nice as Vagrant is, provisioning machines with it has always been a pain. A couple of months ago Mitchell Hashimoto, the creator of Vagrant, launched Packer. Packer lets you build Virtual Machine Images for different providers from one json file. You can use the same file and commands to build an image on AWS, Digital Ocean or for virtualbox and vagrant. This makes it possible to use exactly the same system for development which you then create in production. In this blog post we will show you how you can use Packer to build your vagrant machines. In a follow up post... (more)

Big Data: So What! That’s Why You Virtualize

Big Data!  Yes it's BIG! The volume is BIG!  The variety is BIG!  The velocity is BIG! And hopefully the business value is BIG! New Opportunities Bring New Ways to Leverage Proven Technology There is no shortage of media articles, analyst reports, tradeshows, blogs and other source of Big Data technology insight and advice. But it strikes me that in our search to be on the leading edge, we may be overlooking some great existing technology. In fact, some technology, for example data virtualization, is even more useful in a Big Data world. What Is Data Virtualization? Data virtualization is an agile data integration approach organizations use to gain more insight from their data.  This includes traditional sources such as transaction systems, data warehouses and more as well as new sources such the cloud and Big Data. Unlike data consolidation or data replication, data ... (more)

Embracing the New Enterprise IT: Server Virtualization

Virtual servers are rapidly becoming more popular than physical dedicated servers for a variety of reasons. A virtual private server (VPS) acts like a dedicated server in all respects on a software level while allowing multiple servers to be run on a single physical machine. Since most servers aren’t used to their full capacity, this is a cost-effective solution that provides many technological benefits.   How virtual private servers fit into the new IT landscape Current information technology is allowing companies of all sizes to take new approaches to how they handle their data centers. VPSs that are hosted remotely can replace a dedicated onsite server, moving companies towards decentralization and away from a reliance on in-house technology. Additionally, small and medium-sized companies are now finding that they require technology to remain competitive. VPSs al... (more)

Red Hat Hires Azure Guy to Run Virtualization

Red Hat has hired Radhesh Balakrishnan out of Microsoft's Asia-Pac region where he was responsible for the Windows Azure cloud platform business, to lead its virtualization technologies and solutions worldwide, which includes Red Hat OpenStack and Red Hat Enterprise Virtualization Technologies and Solutions. The company said in a statement that "Virtualization is the cornerstone of cloud computing and Kernel-based Virtual Machine (KVM), which serves as the foundation for Red Hat's virtualization initiatives, is a predominant hypervisor in the cloud....Under Balakrishnan's leadership, Red Hat plans to expand its Red Hat Enterprise Virtualization offerings as well as deliver enterprise-class Infrastructure-as-a-Service (IaaS) solutions powered by OpenStack." The job is central to Red Hat's open hybrid approach to the cloud, according to Paul Cormier, president of p... (more)

Uber Taxis and New Business Models

A recent post by John Wilmes on the TM Forum website caught my eye for drawing a parallel between the Uber car service business model and the telecom service provider business model as network functions virtualization (NFV) becomes a reality. Wilmes uses this metaphor to remind us of the potential value of dynamic pricing as a tool in carrier efforts to match supply to demand. He also cautions service providers to be careful how they sell the message of dynamic pricing to their customers. So far, so good. However, this gave me pause: "NFV will let them [operators] create more of almost any part of their infrastructure on the fly, and turn it off when no longer needed, but that too comes at a price - one that is proportionately much higher than what Uber faces. While Uber needs only to make minimal investments in drivers who furnish their own cars, operators also have... (more)

Rethinking Enterprise Networks: Transformative Approach to Fuel the Cloud

It's clear that cloud computing has transformed the enterprise IT landscape, from the computing infrastructure layer up through enterprise software, as companies move to leverage more efficient and cost-effective service-delivery models and bring new cloud-based products and services to the market. Perhaps less known is the innovation taking place at the network level and how leading companies are transforming their Wide Area Networks (WAN) to more quickly and efficiently fuel their move to the cloud. Moving to the cloud requires network managers and IT shops to implement scalable solutions that ensure the reliability and performance of cloud-based applications across their extended enterprise. Cloud computing drives the need for more reliability across the WAN and ever-increasing amounts of highly available, secure and reliable bandwidth across all users, locations ... (more)

A New DNS for #IoT and #DevOps | @CloudExpo #AI #ML #RTC #DNS #M2M

Goodbye, Open Source: A New DNS for a New Internet BYOD. IoT. Cloud computing. DevOps. IT professionals today have more demands (and more acronyms) on their time than ever. Application development and delivery are changing rapidly and increasing in complexity, revealing the limitations of traditional DNS approaches in achieving modern network goals. The IT department has made use of open source platforms for decades to provide DNS and traffic management in their internal networks and for their public, internet-facing services. The majority of DNS servers, both on the internet and in enterprise intranets, are open source-based solutions such as BIND, djbdns, PowerDNS, gdnsd and NSD. It can feel like shoving a square peg into a round hole to try to adapt these solutions to perform the functions needed in today's environments. In addition, even with complex customizatio... (more)

Separating Fact from Fiction By @DanteMalagrino | @CloudExpo [#Cloud]

Virtual Mythology: Separating Fact from Fiction in the Virtual Network Services Market While many hardware vendors publicly appear to be embracing the move to virtual Layer 4-7 network services, the reality is quite different. To sell virtual appliances - such as load balancers, firewalls, VPNs and intrusion prevention systems (IPS) - they have to overcome the fear of cannibalizing their hardware product line. As companies that have been solely focused on promoting hardware in the past, they don't immediately recognize how virtual services can enable a wide variety of new use cases and, as a result, increase revenue opportunities. They instead focus on virtual services as one-for-one replacement of existing solutions. If that's not enough to stall any transition to marketing the new offerings they do actually want to sell - or more accurately, ones that customers w... (more)
