Unprecedented levels of complexity in the network have been observed due to the continued evolution of IT infrastructure and the shift towards multi cloud application strategies. The scale and diversity of modern networks cannot be managed by traditional WAN architecture, leading to not being able to manage networks effectively and provide the reliable and secure connectivity, based on user's demand.

The expansion, spread and growth of cloud applications has created a distributed and fragmented network environment. As a result of which, consistent performance and security across multiple locations cannot be ensured. Additionally, the network landscape has been further complicated with the increasing number of devices and users.

A transformation of network infrastructure was genuinely needed, to simplify the network environment and ensure secure and reliable connectivity across all locations. A solution was required, which can adapt to any kind of changes in network and users and capable to scale with any network requirements, as well provide real-time visibility into network performance and security.

This is the scenario, where Cisco Catalyst SD-WAN was introduced. By leveraging advanced networking and security capabilities, Organizations have become capable to manage their multicloud advanced networks and security with Catalyst SD-WAN. The operations have become simplified and application performance is also optimized.
