How does multi-application SD-WAN achieve business continuity—Vecloud

Internet connection has become the foundation of modern enterprises. Nowadays, almost every operation requires some form of connection, and if there is no reliable and reliable solution, the company will face serious risks. In fact, most companies can only last a few minutes without a connection.
Therefore, "business continuity" has become the company's primary need. In this article, we will define business continuity and show how to implement it with SD-WAN.
First of all, what is business continuity?
Business continuity refers to the ability of a company to maintain its operation even when it is disturbed by weather, human error and operational failure. A reliable business continuity strategy will include strategies to protect the company from severe network outages to ensure maximum uptime.
It should be noted that business continuity is often used in conjunction with the term "disaster recovery", although they are slightly different. Disaster recovery refers to the process of using backup and hosting services to prevent data loss in the event of a network interruption.
By developing a sound business continuity plan, companies can reduce the possibility of having to initiate a disaster recovery agreement.
How multiple applications can achieve business continuity
Provide business continuity through a powerful software-defined wide area network (SD-WAN) solution, which is designed for service providers. With SD-WAN solutions, service providers can provide their customers with network and Internet business continuity.
SD-WAN works as follows:
Provide a software platform located in the service provider's data center. The management server that works with multiple aggregation servers acts as a single platform that partners can use to manage the SD-WAN deployments of all their customers.
Therefore, customers (such as a global company with 50 to 100 branches) may contact service providers that require business continuity. The service provider provides customers with edge or customer premise equipment (CPE in the form of a common x86 box) and installs one at each branch location of the customer. One port on the CPE is connected to the customer's local access network (LAN) and equipment, while the other ports are connected to multiple Internet circuits from multiple operators.
The SD-WAN solution can be used with almost any type of circuit, including DSL, cable, LTE, optical fiber, T1, P2P wireless and so on. The more circuits that enter the customer's site, the greater the flexibility or failure prevention capabilities of the customer's connection, and the less likely their network will be completely paralyzed. With this setting, seamless failover and true business continuity can be established.
Generally, customers will use two different types of circuits and wireless connections. For example, there may be cable and DSL or cable, DSL plus LTE. With these types of connections, it is realistic to achieve close to 99.999% reliability and uptime.
SD-WAN can create a dedicated WAN between all these branches, enabling QoS and encryption between all sites. This setup is very similar to MPLS. However, it provides more functions and provides the
same services as traditional MPLS Internet deployments.
What about customers who want to keep the MPLS configuration?
There is no doubt that customers will want to know how SD-WAN aligns with their current MPLS deployment. There is a common misconception that it must replace another. It turns out that SD-WAN can be combined with MPLS. MPLS guarantees the stability of key applications on the customer's network, and SD-WAN provides a low-cost connection solution.
