Objective: Software Defined Networking is able to provide, Flexible, Reliable networking that inturn provides support for application and workload services.
Key talking points: By virtualizing the Network we can achieve many benefits. Flexibility come in the form of the speed at which both physical and virtual network components can be designed and configured. The flexibility is provided by being able to move away from the requirement to modify setting on individual devices during setup or configuration changes. As network span across both physical location and various sets of devices a key component comes from the ability to centrally manage the end to end environment Virtual network environments need to provide this flexibility without sacrificing performance, this is achieved by building scale into the virtual network components as well as leveraging key hardware capabilities to ensure optimized performance As datacenters start to leverage the rich capabilities and services available through a cloud environments such as Azure. We will want to provide various connectivity options which can be adjust for both throughput and security considerations.
Objective: Show how the capabilities in Windows Server enable connectivity between sites and to Azure
Key talking points To leverage the capabilities of Azure we need to provide a was to connect in a way that extends your datacenter, and provides various controllable levels of network performance and security.
Slide Message: Extending your datacenter into Azure can be done through two alternate mechanisms.
One of the ways is to have traffic traverse across the public internet (using various encryption technologies) and many different performance levels based on bandwidth allowances. The other way is to provide a dedicated network in which the security and throughput can be managed and audited fully from one end of the connection to the other. ExpressRoute gives you a fast and reliable connection to Azure making it suitable for scenarios like periodic data migration, replication for business continuity, disaster recovery and other high availability strategies
ExpressRoute for Office 365 will include both inbound and outbound scenarios.
Slide 13: Reimagine networking
When we look at datacenter transformation, networking is an area with huge potential. Today’s networks can be rigid, meaning that they make it difficult to move workloads within the infrastructure, and network operations involve high levels of manual processes.
As a result, one of the biggest trends today is software-defined networking. What exactly does that mean?
A big part of SDN is network virtualization, a capability that we offer today in Windows Server 2012. Network virtualization does for the network what server virtualization did for compute. It allows you to use software to manage a diverse set of hardware as a single, elastic resource pool. If you then add in additional management capabilities through software, you get a very flexible approach.
And the benefits are very similar for networking. With compute capacity, we see with the private cloud model how virtualization gives you increased flexibility in moving workloads and allocating capacity. You get greater efficiency when you have this increased ability to balance the load across your existing resources.
With Windows Server 2012 R2 and System Center 2012 R2 Virtual Machine Manager, your network becomes a pooled resource that can be defined by software, managed centrally through automation, and extended beyond your datacenter.
Networking today is complicated because the underlying physical network hardware such as ports, switches, and routers tends to require manual configuration. Network operations are often complex since the management interfaces to configure and provision network devices tend to be proprietary; in many cases, network configuration needs to happen on a per-device basis, making it difficult to maintain an end-to-end operational view of your network.
With a virtualized network infrastructure, you can control the building of the network, configuration, and traffic-routing using software. You can manage your network infrastructure as a unified whole, and that allows you to do three very important things: you can isolate what you need to isolate, you can move what you need to move, and you can build connections between your datacenter and cloud resources.
So let’s first talk about isolation. We’ve talked a lot about the importance of a unified resource pool, but there are many reasons why you might want to create divisions or partitions within that pool. For example, you might want to separate individual departments. As companies increasingly rely on central datacenters to support global operations, you might also want to separate geographical regions. Today, some companies create separate areas for physical servers, designated to particular geos, within the datacenter. But that isn’t a very efficient usage model, and it doesn’t give you many options if that set of servers experiences problems. With network virtualization, or software-defined networking, you can create boundaries within the datacenter to enable multi-tenancy and keep workloads isolated from each other without placing them in separate hardware pools.
What else can you do with a virtualized network infrastructure?
In the past, individual workloads were pretty tightly coupled to the underlying physical network infrastructure. That meant that moving workloads within the datacenter required extensive manual reconfiguration. Network virtualization lets you move workloads even from one datacenter to another because the control plane for the network is all handled through software. We have a number of features in Windows Server 2012 and Windows Server 2012 R2 that combine to make that process even easier.
Connect to clouds:
And finally, software-defined networking lets you connect easily to clouds outside your datacenter. It allows you to treat cloud resources as an extension of your own infrastructure—so in a way, you could say that SDN and network virtualization are the keys to hybrid. That’s why we continue to invest so heavily in this area, and that’s why we offer all of these features in the box.
Slide 30: Hybrid networking
Express Route: connect directly to Azure from your datacenter, without going through the public internet.
Azure ExpressRoute enables you to create private connections between Azure datacenters and infrastructure that’s on your premises or in a colocation environment. ExpressRoute connections do not go over the public Internet, and offer more reliability, faster speeds, lower latencies and higher security than typical connections over the internet. In some cases, using ExpressRoute connections to transfer data between on-premises and Azure can also yield significant cost benefits.
With ExpressRoute, you can establish connections to Azure at an ExpressRoute location (Exchange Provider facility) or directly connect to Azure from your existing WAN network (such as a MPLS VPN) provided by a network service provider.
