For many IT organizations that are beginning to adopt a multi-cloud architecture, SD-WAN has become the main entry point for branch and edge communications with the cloud environment. For customers, the key is to purchase technology that can check all possible paths, and then select the best shipping option directly from the branch to achieve the best performance. This can achieve consistency from the branch or edge to the IaaS cloud environment anywhere in the world. Multi-
cloud requirements
Multi-cloud is usually defined as the use of two or more IaaS platforms, such as AWS, Microsoft Azure, Oracle Cloud Platform, and Google Cloud
Platform. Today, most organizations use various on-premises (data center) and cloud-based resources to achieve agile IT operations. These IT organizations manage a series of private clouds, public clouds, and
SaaS platforms, which provide developers with flexibility to run applications on the most suitable platform and provide users with an excellent quality of experience.
Multi-cloud SD-WAN requirements
Distributed organizations mainly use SD-WAN
platforms to increase bandwidth, improve security, and provide application priority to the network edge. The IT team can deploy SD-WAN internally with the help of channel partners or as a managed service. SD-WAN providers aim to continuously improve the functionality of their platforms through traffic identification and routing, enhanced network security, and better centralized management
. The following are some of the key SD-WAN features needed to support multi-cloud connectivity.
In order to support a multi-cloud environment, SD-WAN requirements go beyond the scope of traditional hybrid WAN connections, allowing application delivery at the time and place the end user needs. Application delivery. In order to support a multi-cloud environment, SD-WAN requirements go beyond the scope of traditional hybrid WAN connections, allowing application delivery at the time and place the end user needs. SD-WAN requirements include seamless connections from users to private clouds, IaaS and SaaS platforms based on defined business strategies, as well as active flow control and prioritization.
Reliability and quality. Since many cloud applications are critical to the business, the SD-WAN platform must provide high reliability and user experience quality (such as low latency) as well as appropriate security and compliance strategies.
Security and visibility. Improved security and contextual awareness in the platform and through partners is essential to counteract the inherent dangers of Internet, cloud and IoT vulnerabilities. The SD-WAN platform needs to check the source and destination of the
traffic to whitelist and isolate the traffic flow. SD-WAN technology must provide IT and security administrators with implementation options through the data center or edge.
Micro-segmentation. For customers in a multi-cloud environment, security requires the platform to have micro-segmentation capabilities to isolate certain traffic, applications, and network segments. In addition, the low latency requirements of IoT traffic require a platform to identify, protect the traffic and route it to the appropriate resources. Many SD-WAN providers can identify real-time traffic and determine its priority.
Connectivity. Connecting to multiple IaaS platforms usually requires a lengthy manual process to enable appropriate routing tables and complex tools to solve the traffic drop problem. Some SD-WAN technology providers can provide automatic connections with leading IaaS cloud environments and tools to quickly identify and correct application performance degradation.
Partnerships. SD-WAN vendors are also committed to quickly improving the way they handle customer expectations in a multi-cloud world. Suppliers are working with leading IaaS providers (Amazon and Microsoft).
