Software-defined networking (SDN) is enabling organizations to accelerate application deployment and delivery, dramatically reducing IT costs through policy enabled workflow automation. SDN technology enables cloud architectures by delivering automated, on demand application delivery and mobility at scale. SDN enhances the benefits of data center virtualization, increasing resource flexibility and utilization and reducing infrastructure costs and overhead. SDN accomplishes these business objectives by converging the management of network and application services into centralized, extensible orchestration platforms that can automate the provisioning and configuration of the entire infrastructure. Common centralized IT policies bring together disparate IT groups and workflows. The result is a modern infrastructure that can deliver new applications and services in minutes, rather than days or weeks required in the past.
Software-defined networking delivers speed and agility when deploying new applications and business services. Flexibility, policy, and programmability are the hallmarks of SDN solutions, with a platform capable of handling the most demanding networking need of today and tomorrow. Ignite business agility with software-defined networking. Today’s enterprise data centers serve a dynamic and unpredictable business environment where IT is tasked with maintaining control of strategic assets on premises while delivering cloud capabilities across the enterprise. SDN delivers the cloud architecture that businesses need for greater flexibility and agility, while bringing hyper-efficiency to your data center. Technologies are the foundation of SDN across the range of software and hardware platforms — from leading vendors as well as open source. Whether it’s a move to software-defined compute, storage, or networking, SDN builds agile enterprises ready for the cloud. SDN can drive positive impacts for your business.
SDN — Network Functions Virtualization
Take control of your hybrid workloads, including running them in containers, and move them across servers, racks, and clouds using standards-based overlay networks and multi-tenanted hybrid gateways. Network Controller allows you to use Network Functions Virtualization to easily deploy virtual machines (VMs) for Software Load Balancing (SLB) to optimize network traffic loads for your tenants, and RAS gateways to provide tenants with the connectivity options they need between Internet, on premise, and cloud resources. You can use network controller to manage a data center firewall on VMs and Microsoft Hyper-V hosts. Microsoft Network Platform uses new features for existing Microsoft technologies, you can use DNS policy to customize your DNS server responses to queries, use a converged NIC that handles combined Remote Direct Memory Access (RDMA) and Ethernet traffic, use Switch Embedded Teaming (SET) to create Microsoft Hyper-V virtual switches connected to RDMA NICs.
SDN — Managed Network Security
Dynamically segment your network based on workloads by using a distributed firewall and network security groups to apply rich policies within, and across, segments. Plus, layer enforcement by routing traffic to virtualized firewall appliances for even greater levels of security. The impact of changing customer demands for capacity, downtime expectations, application performance and user experiences tends to be that IT operators must not be constrained by infrastructure available in a single location. To date this has resulted in several complex scenarios including stretch clusters and Layer-2 extension. What we learned in getting Microsoft Azure public cloud services to where they are now, where an estimated 100,000 virtual networks are on-boarded every month, is that the simplest scenario is to build an overlay SDN. In this style of networking virtual networks are built on top of, and abstracted from, the physical network so that tenants and workloads are isolated from one another.
The concept of the software-defined network (SDN) initially caused some confusion in IT, but the picture gets clearer the more we learn. Similar to network virtualization, SDN allows for the direct network-related abstraction of services. This abstraction of services can be accomplished on both logical as well as physical infrastructures, but is not actually defined by specific physical devices or logical components. Software-defined technologies are already creating new ways to abstract resources at the enterprise level, and products are coming onto the market that allow IT departments to benefit from SDN.
VMware's network virtualization capabilities at the cloud and hypervisor layer can traverse large networks to deliver local and hybrid cloud services. As an alternate approach, Cisco sells its line of Nexus switches, which support the upcoming Application Centric Infrastructure (ACI) SDN platform. Effectively, this provides SDN on physical devices that are capable of very complicated network configurations spanning many datacenter nodes.
The cloud model of computing is here to stay. But, like all technologies, the cloud is evolving. Driven by both the enterprise and the end-user, cloud computing is becoming a more unified infrastructure. Users are able to access content that spans numerous environments via hybrid platforms that extend the datacenter infrastructure out to them. At the core of this design are the networking components that interconnect and support these massive datacenter platforms. Future networking services will unify cloud processes even more, making hybrid cloud creation much easier.
Software-defined networking (SDN) technologies are already creating new ways to abstract resources at the enterprise level, and products are coming onto the market that allow IT departments to benefit from SDN. For example, VMware's network virtualization capabilities at the cloud and hypervisor layer can traverse large networks to deliver local and hybrid cloud services. However you choose to begin exploring SDN, it's an exciting time to be in the datacenter and infrastructure world. Moving forward, the datacenter and its core components will continue to play a critical part in data delivery. Technologies like SDN help to optimize the networking layer of operations, allowing enterprises the capability to do more with the modern infrastructure environment.
To stay competitive, your organization must adapt to change faster than ever. The complexity of your apps, cloud workloads and network change requirements can prompt you to conduct business in smarter, more agile ways. Your network is a great place to start. But to stay ahead of changing market conditions and network demands, new hardware deployments and reconfiguration requests can’t take your IT team weeks or months to handle. It’s one challenge among many that business and IT leaders face today. Cyber threats continue to rise in sophistication and severity, jeopardizing brand reputation.
New networking innovations must create better ways to keep dispersed teams connected. An agile, global technology platform is essential to deliver the best possible customer experience across every channel. Speed up your processes and make your business more agile with better network management services. IAM Networks software-defined networking (SDN) and Network Functions Virtualization (NFV) solutions help automate and simplify your network to quickly respond to change. With software defined policies for precise performance and security, the Managed SD WAN service reliably connects your business apps to the right users.
SDN can create very intelligent and globally connected environments. It can also help with load-balancing cloud and datacenter infrastructures. SDN already provides global traffic management by sending traffic to appropriate datacenters based on network logic. Moving forward, SDN will allow architects to create even more fluid automation for data center traffic flow. Efforts like this of will help reduce downtime, increase data resiliency, and make disaster recovery planning more effective.
Near-flawless content delivery. Users are demanding more content to an ever increasing number of devices. Furthermore, they are asking for this content in high definition. Organizations have achieved success building intelligent edge networks that cache rich content closer to the user. Advancements in streaming technologies also allow for rich media to be transmitted live via the cloud. By implementing SDN, network operators will be able to increase network responsiveness, providing a near-flawless experience for the user.
