Virtual Network Fluency

Simply picking up your existing network architecture and moving it to a completely new one is not going to happen overnight

Like moving to IPv6, simply picking up your existing network architecture and moving it to a completely new one is not going to happen overnight. There will undoubtedly still be "traditional" networks hanging around even when SDN adoption is considered mainstream and fully mature. That's the nature of evolution; it doesn't happen in the blink of eye, it takes time.

Right now organizations are faced with a variety of options in networking. From VXLAN to NVGRE, from traditional to software-defined, choices abound today. And chances are that most largish networks will actually take  advantage of  several of those choices, depending on what phase of adoption they're in.

That means heterogeneous networks; or hybrid if you want something shorter and easier to type.

What makes this a nearly untenable arrangement is that applications may be deployed atop two discrete (and not necessarily interoperable) networks and yet need to communicate, and applications still have to be delivered via the appropriate set of L4-7 services to assure available, performance and security.

Which means interoperability challenges may impede adoption of specific SDN-related technologies.

But if we apply the same principles as virtualization and cloud computing - namely that of abstraction - to the service layer we can achieve interoperability and advance the adoption of SDN-related technologies without nearly as much trouble.

That's one of the benefits of F5 Synthesis, specifically its High Performance Service Fabric.

All Networks are Created Equal
The service layer of a data center architecture is able to abstract applications from the underlying network technology and ensure interoperability when it can act as a sort of network gateway. That is, it can translate between the different network architectures, effectively enabling applications on VXLAN virtual networks to communicate with applications residing on NVGRE virtual networks, or across traditional, VLAN-based networks.

Synthesis v1.5 brought with it a lot of updates and changes, and one of those was around virtual networking. Synthesis 1.5 offers full NVGRE and unicast VXLAN support, and enables the High Performance Service Fabric to act as a virtual network gateway. This capability means Synthesis can insulate application architectures from the impact of a heterogeneous network - whether by way of a transitory step to a full SDN-enabled network or as the intentional end result.

Applications can easily be deployed on one, then migrate to another and even another network, without disruption to the L4-7 services critical to their delivery. This capability enables an agnostic approach to the architecture of the L4-7 service infrastructure with respect to the network.

F5 Synthesis is focused on delivering the Software Defined Application Services (SDAS) critical to the security, availability and performance of applications  no matter what type of network may be in use. To that end, all networks are created equal and Synthesis' High Performance Services Fabric will continue to support them all, which means less disruption as organizations transition to or through a heterogeneous network environment.

Cloud Expo Breaking News
Cloud Computing is evolving into a Big Three of Amazon Web Services, Google Cloud, and Microsoft Azure. Cloud 360: Multi-Cloud Bootcamp, being held Nov 4–5, 2014, in conjunction with 15th Cloud Expo in Santa Clara, CA, delivers a real-world demonstration of how to deploy and configure a scalable and available web application on all three platforms. The Cloud 360 Bootcamp, led by Janakiram MSV, an analyst with Gigaom Research, is the first bootcamp that introduces the core concepts of Infrastructure as a Service (IaaS) based on the workings of the Big Three platforms – Amazon EC2, Google Compute Engine, and Azure VMs. Bootcamp attendees will get to see the big picture and also receive the knowledge needed to make the best cloud decisions for their business applications and entire enterprise IT organization.
Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.

There are 182 billion emails sent every day, generating a lot of data about how recipients and ISPs respond. Many marketers take a more-is-better approach to stats, preferring to have the ability to slice and dice their email lists based numerous arbitrary stats. However, fundamentally what really matters is whether or not sending an email to a particular recipient will generate value. Data Scientists can design high-level insights such as engagement prediction models and content clusters that allow marketers to cut through the noise and design their campaigns around strong, predictive signals, rather than arbitrary statistics. SendGrid sends up to half a billion emails a day for customers such as Pinterest and GitHub. All this email adds up to more text than produced in the entire twitterverse. We track events like clicks, opens and deliveries to help improve deliverability for our customers – adding up to over 50 billion useful events every month. While SendGrid data covers only abo...
