  • Today I’m going to talk about SDN, or Software Defined Networking. As the IT infrastructure ecosphere evolves and becomes more dynamic and service oriented, the networks which ultimately deliver the rich fecundity of data and services to the user must also evolve. Legacy paradigms in this context become limiting to the ongoing innovation of our information superhighways. Tomorrow’s infrastructure must be adaptable and be able to meet emerging needs in real time. SDN technologies are critical to the enablement of this concept.
  • -All gear has a specific functional role with capacities selected at the time of purchase, therefore if needs changed or grew, the entire architecture often needed to be re-designed and deployed-Impacts to cost, time to market, business agility, customer satisfaction, security and availability-High complexity and tradeoffs based on choices The network infrastructures of today use discreet, specific elements which all have capabilities selected at the time of purchase. Whether you needed a router to govern traffic among different networks, a load balancer to distribute user and application requests or a firewall or other security control – these are almost universally delivered in the form of a hardware appliance. These elements are then deployed in one of a few prescriptive ways, based on the needs of the infrastructure at the time of deployment. When you’ve built a network out of traditional components, it’s somewhat analogous to this lego castle in that though the pieces are modular and have some degree of flexibility, many of the elements are highly specialized and cannot be leveraged the same way in a different design. So you decide what type of castle you’re building, you build it and hopefully it allows your lego people to access the various parts of the castle in the right way. If during your adventures, your requirements change, it’s very hard to retrofit your design. You typically need to tear it down and rebuild.
  • Which of course means it’s time to go to the datacenter. Reconfiguration means in many cases both physical and logical reconstruction and in many cases includes shutting down, uncableing and moving mission critical equipment. This operation takes lots of time and planning and entails significant risk to the organization in terms of service downtime and the potential to inadvertently create weaknesses in network security. In the emerging world of API driven applications and dynamic data workflows, a new way to define and scale networks needed to be invented to keep up with the blistering pace of innovation. This new network architecture must change at the speed of collective creativity and scale itself at orders of magnitude in real time.
  • SDN is different:You deploy the physical architecture typically once, based on the amount of port density you require at the timeYou if you need to scale horizontally, you can easily add programmable switches and extend your networkFeatures are just software modules you installApps can dynamical reconfigure port speeds, access rules, security features, create and tear down networks, etc – all without human intervention in many casesWith Software Defined Networking, changes are made dynamically and logically in software, either at the request of the system administrator or potentially based on business rules defined by the organization. Since changes can be made through an API, applications can now send change requests or performance metrics to the network controller, which then implements changes to the infrastructure. This allows new applications as well as changes to existing ones to come online much faster, and for governance and policy enforcement to be automated, which is far less labor intensive and introduces much less opportunity for error.
  • -SDN in the datacenter, you want to start pretty big, but adding capacity is much easier than it used to be-SDN components are far cheaper than traditional ones. The extra cost can be applied to higher speed ports and functional software expertise-Build to scale, both size and featuresThe first core principles of a successful software defined network is to begin with high physical bandwidth. This way you can logically define multiple network flows, lay down parallel networks in test and staging environments to understand the impact of changes and ensure that your network will have sufficient scalability to meet emerging business needs. 10Gb links are quite common while aggregated 10Gb trunks allow for generous horizontal traffic growth.
  • Since standardized units (switches running Openflow) are used, scaling the network is a matter of adding the required port densitySDN networks can be set up to automate configurationSet up a flow to a new endpoint, the software will download and install the required features to the new switchMakes deploying and maintaining a highly scalable architecture much easier and cost effectiveThe second core principle of SDN is standardization of incremental units. Within a properly designed SDN, adding additional performance at any layer should be as simple as incrementing the number of a standard physical component, be it a network interface card or a switch. This ensures that upgrading the capacity of the network does not result in the need to reconfigure any physical devices or make difficult strategic decisions with regard to vendor or device under pressure from an impending or immediate business requirement. Standardization also simplifies the network architecture and helps lower cost due to the effects of commoditization.
  • Once your physical network is set up, begin defining network flows in softwareOpenflow is the predominant southbound protocol in use todayAll features are added in software and ideally can be accessed programmatically If your network requires reconfiguration, you can redefine it in software remotely and often with very limited downtime, since flows can be built, tested, QA’d and then deployed to production using the same physical components as production.Once your physical network is racked and cabled, it’s time to start defining it’s logical architecture. Within the SDN world, we talk about traffic patters in terms of flows. As you can see using hyper-glance, the logical network gets depicted as a set of physically connected elements which can easily be configured to open up or restrict network communications, define quality of service metrics, create logical gateways or deploy firewalls or security inspection points. Since we’ve started with high bandwidth, commodity links to all the elements, if high speed throughput is required to a particular component of an application, it can be changed logically, either by a system administrator or even a request from the application or end user itself.
  • -The business benefits of SDN are numerous -SDN is in fairly early stages of adoption-SDN can work in conjunction with traditional networking (and usually does)To the business, this means a whole host of potential improvements. Application developers can more quickly get their creations to market and organizations can gain better control over content and deploy better security at every layer in their network. New technologies like Hadoop can run unrestricted and gain much faster and more secure access to traditional database information which may be located in different areas of the datacenter. Because all network traffic is defined using a singular interface with a homogenous set of technologies and compatible plug-ins, monitoring the performance of the network is easier and problem remediation much faster, reducing loss exposure and risk.
  • -Consider the various technical tasks an IT shop has to perform to provide access to an application today-It’s not only a laborious process, but one which involves multiple groups, network, security, application and dev teams, etc.-SDN creates a “service-based” network infrastructure for the business-Applications will know where and how they’ll need to be available to users, through what channels, at what speed/QOS and with what security controls-Apps will send out a request with pre-programmed authorization credentials to the network infrastructure, and get back a list of available options-The application will select the options it requires and send back a request to the network infrastructure-The network infrastructure will configure itself based on what the application needs, which may change dynamically throughout it’s lifecycleAnother way to look at SDN, is that it offers the network “as a service” to administrators and applications. Once the network team has selected the set of tools and defined the business policies governing the data within their organization, the network becomes a virtual marketplace of communication services. Applications can openly voice their needs and the network can work with them to solve these challenges. As applications change to offer a wider number of services and greater levels of performance, the network responds in real time.
  • As service oriented applications gain adoption, SDN will be called upon to support the networks which provide access to themPower of automation and standardizationMoves networking professionals up the value chainWith the myriad of benefits SDN provides, it’s clear why it’s the future of networking within the datacenter. As with any emerging technology, the early adopters are rapidly blazing new pathways and opening up new value within the SDN ecosystem. They’re also exploring it’s weaknesses and finding areas which require growth and attention. Bill Gates once said: “Automation applied to an efficient process magnifies the efficiency, while automation applied to an inefficient process magnifies the inefficiency.” Considering an implementation of SDN within your own environment often becomes a journey which traverses many departments and challenges incumbent rules, policies and cultural traditions within the organization. But for those companies willing to take on the challenge, a new world of simplicity and automation await them. *pause*Thank you for your time today. I hope you enjoyed this presentation.
