One of the essential tools for any business is its network, especially for those that provide technology as a service. Bandwidth dictates the capacity of your network. With SD-WAN, you can combine several WAN connections and access their power of them all at once. In addition, this type of network is flexible and offers guaranteed QoS. Ultimately, as SD-WAN explained this tool makes your network more efficient and effective.
SD-WAN Simplifies Cloud Migration
SD-WAN is a software-defined network that allows businesses to migrate to the Cloud easily. This new technology is flexible and supports a range of critical enterprise use cases. It can provide secure internet access to users in multiple locations and optimize traffic flow to and from the Cloud. Additionally, SD-WAN is scalable and allows for incremental deployments. By using an SD-WAN, enterprises can prioritize critical applications and reduce the attack surface of their network.
The traditional WAN architecture is based on the premise that applications are hosted in a central data center. To access these applications, traffic from branches must backhaul to the data center. This slow method can result in poor picture quality or audio fading. Using SD-WAN, users can access cloud applications directly without traveling back and forth. SD-WAN can also simplify migration, allowing a business to switch carriers easily.
SD-WAN can be a DIY solution, or an enterprise can hire a managed service provider to manage the process. With an SD-WAN service provider, the network administrator does not need to worry about infrastructure or software maintenance. In addition, managed service providers can handle the integration of cloud applications, which means no additional investments. With these managed services, the complexity of the cloud migration process is reduced significantly, and the benefits are felt immediately.
More Flexible than MPLS
One of the most significant differences between MPLS and SD-WAN is flexibility. The former provides centralized management, while the latter offers flexible routing paths. In addition, SD-WAN can aggregate multiple connections for high-speed Internet access and traffic path encryption. The last enables companies to use low-cost, fast broadband internet access. Unlike MPLS, which has historically locked companies into their service provider, SD-WAN is highly flexible.
With SD-WAN, networks can make intelligent decisions on where to route traffic. This software-based network can be connected to the internet, data centers, and other business branches. It can use a variety of transport services, including MPLS. MPLS is a network technology that directs data through a path using labels. However, MPLS requires proprietary hardware. This makes SD-WAN more flexible.
While MPLS has a long history in the telecom industry, it can become obsolete over time. This is because new technologies and protocols can be developed, and older methods become outdated. If MPLS were perfect, it would not need competition. However, SD-WAN is more flexible and can accommodate more needs than MPLS. However, it can’t replace MPLS. However, SD-WAN is an excellent alternative to save money and be more flexible.
Provides Guaranteed QoS
The first step in ensuring the performance of your SD-WAN is identifying how traffic is prioritized. With SD-WAN, traffic is determined according to its business priority and is queued accordingly. This ensures that only the most essential traffic is served and that it receives enough WAN resources to fulfill the needs of your business. The next step is determining how much bandwidth is needed for different applications. Then, traffic shaping starts, ensuring that only the most essential traffic receives adequate WAN resources.
To achieve this, SD-WANs need multiple links for failover and load-sharing purposes. Business-class service-level agreements do not require single-link networks. SD-WANs typically use two or more links; some have cellular connections as backups. This way, if one of the links is down or the other fails, the remaining traffic will still be routed to the alternate link. This guarantees the performance of your critical applications and services and allows your IT team to troubleshoot any issues.
In addition to guaranteeing QoS, SD-WANs offer flexibility in policy creation. Instead of using separate routers for different traffic classes, SD-WANs use centralized WAN controllers to manage all adjacencies among nodes in the network. Using SD-WAN, policies can be dynamically altered according to the current network condition. As each router advertises its information to the central controller, policies can be enforced on every local router.
