Cisco Catalyst SD-WAN Reviews

The primary use case for Cisco SD-WAN is the standard configuration across all sites, facilitated by templates. This solution helps in the ease of management and compliance configuration, which is deployed everywhere. 

It also simplifies troubleshooting and provides full mesh topology for branch connectivity to data centers. All branch locations, along with central locations, are on SD-WAN and gathered in the data center. Many customers combine it with local Internet breakout for SaaS applications.

The valuable features of Cisco SD-WAN include its security policies and zone-based firewall that are applied to every site, as well as application-aware routing. Security is standard compliant, eliminating config drift that was prevalent before manual configurations. Application-aware routing offers flexibility in using different lines for traffic, depending on the policy implemented.

The main use cases for Juniper vSRX would be primarily for a data center scenario device, and there's a significant focus on the other core elements.

Cisco Catalyst SD-WAN's main use cases for us will be data center deployment for enterprise level.

The most useful feature for Cisco Catalyst SD-WAN is the single pane of glass management because we also use Meraki onsite. It's a standard Cisco solution, and because Cisco is who they are and what they can provide, we use Cisco for compute and network, and we use NetApp for storage, so that's what we generally do.

I have absolutely seen scenarios where the decentralized management capability improved operations and workflows.

The primary use case for Cisco SD-WAN is to connect multiple offices or branch offices across the globe or within a country securely. It facilitates branch-to-branch or office-to-office transactions and provides easy access to primary data centers.

Cisco SD-WAN is valued for its operational efficiency and ease of operation. It allows prioritization of packages based on production requirements, and integration capabilities provide comprehensive security. Integration with Cisco ISE, Cisco Firewalls, and other Cisco solutions is beneficial. Furthermore, it is appreciated for its insights, visibility, and ease of use.

Viptela is one part of SD-WAN that can give you an internet connection with the help of stacking. You can create a stack in the environment called a TLOC. With the help of TLOC, you can configure your ISPs in one bundle, giving you the network's resiliency. The best part is that you will get a few connections immediately onto your network.

If one of your ISPs goes down or has latency in your environment, Cisco SD-WAN will detect the issue and explain why the ISP is down. This is the solution's best feature, as it allows you to monitor your ISP links very well from their side. The solution's configuration is easy and not that hard. The solution's central management allows you to raise cases and get support.

My client wants to use SD-WAN to reduce their line costs. By using SD-WAN, they aim to lower transport costs and better use internet traffic and bandwidth.

Clients use SD-WAN, which encapsulates the packet into a VPN tunnel. This allows them to be ready. In SD-WAN, the internet line is generally much cheaper than other lines. For example, they can use DIA to access internet traffic. With strong encryption, such as TLS or IPsec, they can securely send business traffic over the internet at a lower cost.

We use the solution to do a lot of proof of concept to evaluate the deployment, manageability of the solution, application availability, scalability, and cloud. These include secure cloud security integration with Umbrella and software-defined cloud interconnect (SD-WAN) use cases. We also evaluate end-to-end segmentation use cases.

In general, Cisco SD-WAN is a scalable tool that simplifies network management. It can be a great way to transform a legacy network into a more standardized one, which can help reduce operational issues.

Over time, a regular network with different point solutions can become very complex. There are different vendors for WAN, LAN, cloud security firewalls, etc. Each device may be configured separately, and each region may have its own IT team with its own way of working. All of it has created silos over the years. If you want to make a change or a rollout, It takes a lot of time to do a risk and impact assessment because there are hundreds of teams and hundreds of devices. Every device and no team or no region has a similar type of configuration. There is no useability. There are no template extensions. Every device is configured differently depending upon the liking of the individual who has done it on the first go. 

However, with Cisco's SD-WAN, when you manage it through a central dashboard, you use templates, etc. You build that standardized configuration or discipline, for that matter, and you maintain it.

You have a common policy repository, and standard template, and use one template to configure 50 devices or one. If you have 100 similar devices, we do the same thing, which is very easy. It'll be too extreme, but it'll be far easier to understand that if I work 100 branches, this is how the branch organization will look. If I have 50 medium-sized branches or a corporate office, this is how the configuration will look.

The solution gives an immense opportunity for standardizing the network configuration. It reduces mean repair time, mean deployment time, and uses and predictability in operation. This will also improve your first-time deployment because the network is more predictive. Since I've been in the industry for 20 years, every time you make some change, you are 90% expecting one or the other surprises, which you'll have to deal with during the maintenance window. 

Cisco enhances these aspects by providing an opportunity to make networks simpler. Simplicity is crucial for multiple family networks, and Cisco ensures improvement without unnecessary complexity.
