There’s been a lot of news and momentum surrounding VXLAN technology in the last several months, and there is no doubt that VXLAN is becoming a more strategic and pervasive technology across cloud networks as a result. When we rolled out VXLAN about two years ago with the first commercial implementation as part of our Nexus 1000V virtual switch, VXLAN was solely a virtual networking construct and had real constraints in how it could be extended to physical networks and devices. It was also restricted to overlay networks using our Nexus 1000V switch (or other virtual switches supporting the VXLAN overlay protocol).
Now, however, VXLAN is being supported broadly across Cisco networking platforms and devices, across multiple Cisco fabric architectures, and we are even seeing broader support from other vendor ecosystems and non-Cisco switching platforms. Cisco is continuing to expand its support for VXLAN onto the new Nexus 5600 Series switches, as well as Nexus 7700 Series using the F3 line card.
For those of you not fully up to speed on VXLAN, VXLAN stands for Virtual eXtensible Local Area Network, and started out as vastly more scalable Layer 2 LAN and tenant isolation construct for data center and cloud networks. Where cloud networks were running out of only 4000+ VLAN IDs to segment application networks, VXLAN gave them over 16 Million logical network segments.

At Cisco Live! Milan, I talked with people from all types of organizations from around the world and hearing their excitement at how they envision the cloud is going to change the way they do business. Their stories are incredible and inspiring. They range from a small startup hoping to expand their business without having to create their own IT department all the way to global companies looking for ways to deliver new services faster in a more secure and cost-effective manner.
No matter the size of their organization, they are all looking for similar things. Assured performance is top-of-list for most. Faster to time market is another important factor. Many are turning to the cloud for a competitive edge that lets them take advantage of continuous innovation without having to reinvest in a completely new data center. And most are looking forward to the cost savings of not having to manage their own IT infrastructure. However, what’s often not talked about is that behind every cloud service is a network that is responsible for the performance of your data and applications. And the truth is, not all cloud services are created equal.

The Cisco Prime Network Services Controller team is pleased to announce the availability of 3.2 release. This release incorporates a number of new features and functionalities to build virtual data centers (VDCs) with various network topologies. Follow this link to download the software and documentation.
Designed for multi-tenant cloud deployments, Cisco Prime Network Services Controller offers scalable, and automation-centric management for virtualized data center and cloud environments. The Cisco Prime Network Services Controller is a virtual appliance that provides centralized device and policy management of virtual networking services. It provides a unified northbound API (XML payload over HTTPS) to allow the creation of dynamic data center that includes switching, routing, fire-walling and load-balancing functions.
Cisco Prime Network Services Controller is built on an information-model architecture in which each managed device is represented by its subcomponents (or objects), which are parametrically defined. It also uses Services profiles for model-based configuration of virtual devices policies. A service profile is a collection of device policies and configuration templates that can be predefined and applied on demand at the time of virtual appliance instantiation or later. Cisco Prime Network Services Controller enables
- Flexible and simple mechanism to managing virtualized infrastructure using Cisco VSG, Cisco ASA 1000V, Cisco CSR 1000V virtual services as well as Citrix’s NetScaler virtual load balancers (NetScaler VPX and NetScaler 1000V)
- Cisco InterCloud for virtual machine (VM) workload management and migration between the enterprise data center (private cloud) and public clouds
- Cisco VSG, Cisco ASA 1000V, Cisco CSR 1000V, NetScaler VPX and NetScaler 1000V services in Dynamic Fabric Automation (DFA) solution

Cisco announced last week that its rapidly expanding ACI ecosystem now includes the A10 Networks aCloud Services Architecture based on the Thunder ADC Application Delivery Controllers, as well as the Catbird IDS/IPS virtual security solutions. These new ACI ecosystem vendors are announcing support for the ACI policy model and integration with the Application Infrastructure Policy Controller (APIC) which will accelerate and automate deployment and provisioning of these services into application networks. This should also resolve any speculation that the ACI ecosystem would not be including technology vendors that compete with Cisco’s other lines of business, as Cisco expands the solution alternatives for customers.
Each of the solutions will rely on two primary capabilities of the APIC and ACI to provide a policy-based automation framework and policy-based service insertion technology. A policy-based automation framework enables resources to be dynamically provisioned and configured according to application requirements. As a result, core services such as firewalls, application delivery controllers (ADC) and Layer 4 through 7 switches can be consumed by applications and made ready to use in a single automated step.
A policy-based service insertion solution automates the step of routing network traffic to the correct services based on application policies. The automated addition, removal, and reordering of services allows applications to quickly change the resources that they require without the need to rewire and reconfigure the network or relocate the services. For example, if the business decision is made to use a web application firewall found in a modern ADC as a cost-effective way of achieving PCI compliance, administrators would simply need to redefine the policy for the services that should be used for the related applications. The Cisco APIC can dynamically distribute new policies to the infrastructure and service nodes in minutes, without requiring the network be manually changed.

In my last blog, “Has Hybrid Cloud Arrived? Part 1: And How Will it Shape the Role of IT Going Forward?” we looked at the business drivers of a hybrid cloud and previewed the key requirements. In this blog, we will look at Cisco InterCloud – a hybrid cloud solution, we announced this week at Cisco Live! Milan, to address the hybrid cloud needs for enterprise and service provider customers.
Business leaders today are heavily growth-oriented and are looking at new ways of deploying applications to obtain greater agility. That is where we see hybrid cloud becoming mainstream as it frees businesses to run applications on-demand and where it’s most cost-effective. Cisco InterCloud was announced to address this opportunity and facilitate optimal hybrid cloud deployments.
Cisco InterCloud comes with unique capabilities that enable enterprises to connect their private cloud to heterogeneous public clouds. It creates the notion of a single scalable hybrid cloud for all physical, virtual and cloud workloads -- an infinite datacenter where the public cloud is treated as a virtual extension of the data center. Cisco InterCloud is designed with these tenets:
Open: Customers are excited about Cisco InterCloud, as it is an open solution that gives customers the freedom to choose hypervisor on private cloud and select their public cloud from a rich ecosystem of cloud providers. Service providers like InterCloud as it is open API based, integrates with multiple cloud platforms, e.g., CloudStack, vCloud, and OpenStack and enables them to rapidly offer a hybrid cloud solution. It reduces the effort to onboard enterprise customers. Cisco InterCloud thus provides a multi-cloud, multi-hypervisor cloud experience.
Secure: Another key factor in hybrid cloud adoption is the need to address the security and compliance concerns of public cloud deployment. Cisco InterCloud provides end-to-end secure connectivity by encrypting traffic between the enterprise private cloud and the service provider cloud. It also ensures workload security by encrypting all data-in-motion within shared multi-tenant public cloud. Additionally, customers can also deploy network services such as zone based virtual firewall and edge firewall for further workload security within public cloud.
Flexible: Customers demand bi-directional workload portability across private and public clouds. With Cisco InterCloud, customers not only can provision workloads from a self-service portal, but also with a click, migrate workloads to the public cloud and back. All of this activity happens behind the scenes as InterCloud converts workloads to the right VM format, such as VMware VMDK to AWS AMI, or to CloudStack format for providers such as BT. It makes workload portability easier as applications don’t need to be re-architected as IP addresses are retained upon migration and enterprise VLANs are extended into the cloud.
I believe that lines of business and developers are leading the journey to hybrid cloud adoption. IT has realized that it needs to shift away from its role as gatekeeper to instead being a partner to Lines of Business but IT faces certain challenges in doing so. IT has to deal with the overhead of integrating with each cloud provider and find ways to do in a secure manner. Cisco InterCloud enables IT to act as a cloud broker on behalf of lines of business. Cisco InterCloud provides unified hybrid cloud management through a built-in IT Admin portal and an extensible northbound API layer. It also allows IT to enforce consistent network security, L4-7 services and workload policies throughout the hybrid cloud.
This week’s Cisco InterCloud announcement demonstrates our continued commitment to customers. We envision a future where customers have an array of cloud options and can pick the ‘best fit’ based on workload needs, performance, cost, and location requirements. We are going into beta next quarter and have announced general availability soon afterwards. As 2014 dawns, we see a shift towards mainstream hybrid cloud adoption — hybrid cloud is finally here for real.
