So how exactly do you manage a cloud network? And what are the main characterizations of this new network environment?From an operational flow, look to the right-hand side. An operator– who could be either a cloud ServiceProvider or a large enterprise that is serving different organizations– would need to go through different steps to deploy its services. Starting withService Definition,Environment Set-up, andAnd Resource Allocation.And this new deployment model becomes even more complicated if you are adding all other variables.You can no longer have silo management, as the expectation is to have a self-service portal that allows customers to manage their environment through a single API. Your management solution needs to co-exist with other pieces like hypervisor managers, orchestration tools and element managers.In other words, your environment is not isolated any more, multi-tenancy and collaboration among groups and companies is required.Environments are much larger,traditional 4k VLANs are no longer enough– so we had to come-up with new technologies to address new requirements. The need from a management stand-point is to support those new technologies and be able to scale-up to the new numbers.Static versus dynamic, resources are virtualized, can be mobile, and can be spun-up on the spot and attach to your network.Supporting private clouds only is no longer sufficient, customers may have resources across the private and public environments, so customers are now demanding that they should be able to bridge over secured tunnels and have a management that can expand across boundaries, since customers aren’t willing to have isolated management.All of the above capabilities need to be aligned with new movements like SDN and open flow and enable transparency and API accessibility to the entire feature-set.
All in all, VNMC offers these following benefits:The ability to construct a hybrid cloud environment (and configure solution components with Nexus 1000V)VM operation to manage day-to-day operation activities,Service assurance and alert on service degradation,System Management for single place of operation supporting enterprise management standards,And Management Orchestration to integrate with internal and external management systems.
This is where the Virtual Network Management Center (or, VNMC) comes in. VNMC has been designed with virtualization challenges in mind, focusing on network virtual service deployment.VNMC is a centralized multi-device and policy management tool for Cisco network virtual services, It provides:Rapid and scalable deployment through dynamic, template-driven policy management.Easy operational management through XML APIs to help enable integration with third-party management and orchestration toolsA non-disruptive administration model that enhances collaboration across security and server teams while maintaining administrative separation and reducing administrative errors.VNMC breaks traditional management silos, by abstracting network services data, and exposes them through a single management API. This allow customers to reduce their integration costs, by integrating into a single management platform and API.VNMC is a multi-tenant management solution, and enables the collaboration among server, network and security admin, in an environment that can be managed and overlapped between SP and Enterprise organizations.VNMC Covered Aspects:Building Blocks - Main functionality (in the blue)Multi-Service Support (including Nexus 1000V Intercloud, Virtual Security Gateway-VSG, ASA 1000V firewall, and more)VNMC is Hypervisor agnostic (on the far right)Multiple Ecosystem Support (including Cisco Intelligent Automation for Cloud, vCloud Director, and more)Advanced Capabilities (far left)
At its core, VNMC is a network management tool that will allow the operation of day-to-day activities, including network infrastructure provisioning and VM (virtual machine)/workload migration across a variety of networks. We are expecting to expand VNMC’s capabilities to Microsoft Hyper-V in our next release, and have already announced the next major release of VNMC 3.0, or VNMC InterCloud shipping later this year which will support hybrid cloud environments in the Nexus 1000V InterCloud solution.Enterprises are increasingly moving to hybrid clouds to gain the benefits of public clouds - agility, on-demand provisioning, pay-as-you-go capability, and elastic scalability - along with the benefits of private clouds. Private clouds have some advantages, allowing enterprises to design and customize their infrastructure and control security. However, private clouds are usually less agile than a public cloud and can be expensive to run to meet peak demand. Cisco Nexus 1000V InterCloud is designed to bridge enterprise and cloud provider deployments in a secure and consistent manner. Based on Cisco Nexus 1000V Series Switches and industry-standard Cisco Cisco Nexus 1000V InterCloud (Figure 1) provides: NX-OS Software, ● Secure Layer 2 network connectivity between the enterprise data center and the public cloud ● Consistent network policies and services across private and public clouds ● Virtual form factor designed for easy deployment ● and finally, single pane of management– this is where VNMC InterCloud comes in.With Cisco Nexus 1000V InterCloud, the enterprise network can be securely extended to the cloud, with enterprise network configurations such as VLANs and policies extended to the cloud. Workloads can be migrated from the enterprise data center to the public cloud while retaining the same IP addresses, thus avoiding the need to redesign the application.
As I just mentioned, VNMC InterCloud presents a single-pane, consolidated view of virtual machines across the enterprise data center and the cloud for the Nexus 1000V InterCloud solution. It also enables virtual machines to be migrated from the enterprise data center to a cloud provider, or a public cloud. In addition, it manages security policies and virtual services in the cloud. This means that apps can continue using common application services that are hosted in the enterprise datacenter, on the cloud. VNMC also features a northbound APIs to integrate with cloud orchestration tools.With this API integration, Cisco Intelligent Automation for Cloud enables users to order private or public cloud services from a self-service portal- Cisco Service Portal. The request is then processed by Cisco Process Orchestrator, the automation engine behind Cisco IAC, which manages workflows across multiple cloud environments. Then, the workloads are moved to VNMC InterCloud to be distributed between the enterprise data center (private cloud) and public cloud providers (public clouds). Here, VNMC provides the crucial ability to manage operational activities for virtual network services in such a complex hybrid cloud environment.
In short, VNMC provides a seamless, secure extension of virtual networks from on-premise data centers to cloud service providers. What you should take away from this is the Cisco advantage:#1 Maintaining consistency across both physical and virtual infrastructure that spans across a hybrid cloud environment. Cisco is the only hybrid cloud enabler that provides consistent policies (such as network policies), consistent applications, and consistent network environment to provide a seamless and secure extension into the public cloud. #2- Workload mobility– Migrating workloads between private and public clouds is becoming a reality, and with Cisco we’re ensuring that it’s a no-nonsense, secure process.#3- An end-to-end hybrid cloud ecosystem, enabled by the northbound API, which allows VNMC to provide high-level, self-service, automatic provisioning of services for the end user via products like Cisco Intelligent Automation for Cloud and other third-party extensions. This means a complete cloud network management solution with full stack delivery by Cisco.
