Hi All,
The Catalyst Engineering team at Cisco has created a variety of design case studies following common use cases for SD-WAN. These case studies are designed to provide an in-depth look into methodologies and technical solutions of how Cisco customers have leveraged SD-WAN to achieve business outcomes.
Cisco Catalyst SD-WAN design case studies help practitioners learn and design based on best practices from experts involved in real customer deployments across multiple industries.
The five following case studies cover different categories of SD-WAN use cases as defined by the technological research firm Gartner.
Small Branch: This category focuses on a use case with remote sites that support up to 10 people, where simplicity, cost consciousness, and flexibility of transport choices are key. Examples of the small branch category include gas stations, convenience stores, small banks, and fast-food restaurants.

Global WAN: This study focuses on large enterprise organizations with 200 to more than 1,000 sites with remote sites distributed across different countries or regions. The Global WAN use case includes the ability to scale hundreds or thousands of sites, typically across multiple geographic regions. Applications include a mix of private DC, public IaaS, and SaaS with increasing resources moving to the cloud. Some examples of this category include global financial institutions, large retailers, and manufacturing environments.

Security Sensitive: Although the number of locations and sites can vary, the focus of this category is to provide a comprehensive security solution combined with a networking solution. It is the typical use case for organizations focused on securing branch offices as the main priority where network and security procurements are increasingly converging. The security infrastructure is delivered as a cloud service or from an SD-WAN appliance, with native security or with the ability to host a third-party security solution at the branch. Examples of this category include financial services, government, some retail, some healthcare, and some regulated industries.

Cloud First: In this study, we focus on organizations that consider the need for easy, high-performance, and flexible WAN-to-cloud access, where most of the business initiatives are cloud-hosted with little to no workloads in on-premises data centers. The goal of this strategy is cost reduction and improved quality and speed of delivery, as cloud-based solutions can be scaled up or down as required.

Remote Worker: This use case focuses on individual workers connecting to the enterprise network from remote locations such as their homes instead of connecting from the branch. Enterprises typically choose a software-driven product or a lightweight hardware solution for single user environments. Security with Zero Trust Network Access (ZTNA), which includes VPN, is the focus with other cloud security functionality based on worker identity and split tunneling to securely connect to cloud workloads.
