Scalability of the Manage

Cisco SD-WAN Fabric is a cloud-delivered overlay WAN architecture that facilitates the deployment of cloud-based applications by optimizing the network traffic between different locations. One of the key components of this architecture is the vManage, which is a centralized management and orchestration platform for the SD-WAN fabric. The vManage provides a single point of control and visibility for the entire network, including policies, configurations, and monitoring.

Scalability is an essential aspect of any network architecture, and it is critical for the success of SD-WAN solutions. The scalability of the vManage can be increased in several ways, including the following:

A. Increase the bandwidth of the WAN link connected to the vManage: The bandwidth of the WAN link connected to the vManage is crucial for managing the SD-WAN fabric. Increasing the bandwidth of the link will improve the responsiveness of the vManage, reduce the latency, and enhance the overall user experience. However, this solution may not be feasible in all cases, as it may require upgrading the WAN links, which can be costly.

B. Increase licensing on the vManage: The vManage licensing model is based on the number of devices, users, and locations managed by the vManage. Increasing the licensing capacity of the vManage can provide additional resources for managing more devices and locations, which can enhance scalability. This solution is relatively easy to implement, as it only requires purchasing additional licenses.

C. Deploy more than one vManage controllers on different physical servers: Deploying more than one vManage controller on different physical servers can provide redundancy and load balancing for the SD-WAN fabric. Each vManage controller can manage a subset of devices and locations, and they can synchronize their configurations and policies. This solution can improve the availability and reliability of the vManage, as well as enhance scalability by distributing the management load across multiple controllers.

D. Deploy multiple vManage controllers in a cluster: Deploying multiple vManage controllers in a cluster is similar to deploying multiple controllers on different physical servers. However, in this case, the controllers are connected to a shared database and communicate with each other in real-time. This solution can provide high availability and fault tolerance, as well as scalability, as the management load can be distributed across multiple controllers in the cluster.

In conclusion, the scalability of the vManage in the Cisco SD-WAN Fabric can be increased by increasing the bandwidth of the WAN link, increasing licensing capacity, deploying multiple vManage controllers on different physical servers, or deploying multiple controllers in a cluster. The best solution will depend on the specific requirements and constraints of each deployment.
