Creating networks that are devoted to the requirements of the applications serve results in security, performance, and manageability improvements.
FREMONT, CA: The hybrid cloud has forced enterprises to rethink the architecture of network resources that are utilized to link these broadly distributed environments because of security, management concerns, and complexity.
These application-driven networks offer a perimeter, which is software-defined, enterprise-grade availability, and the software-defined network management’s flexibility for distributed application components that span private, public, and on-premises environments. These application-driven networks can be quickly deployed and managed easily without any burden of proprietary hardware vendors and their antiquated support, delivery, and management models.
An application-driven network architecture’s premise is that every application is connected to a network segment with its network architecture and security for fulfilling the appropriate application requirements.
There are three keys to application-driven network architecture.
• Networks can be quickly deployed anywhere through a standard set of control and management features.
• Network agnostic functions can be caked on top of any network infrastructure like 4G, ethernet, cloud networks, or private circuits.
• Data and control planes’ separation allows private point-to-point application connections to be monitored by centralized portals across all ambiances.
• Applications, including serverless apps and micro-services, can stay anywhere on the network, which acts as connective tissue application components managed and distributed throughout all network endpoints.
• The network can be handled as code, which is inside the present DevOps processes and toolsets, akin to the way infrastructure-as-a-service is now handled as a code.
• Open components enable for tighter incorporation with ecosystem partners like Microsoft, Amazon, or Slack.’
• All network functions like management, configuration, and supervising are accessible via APIs.
How can we get benefitted from these new architectural strategies?
Some datastores and workloads are not suitable for the cloud because of numerous reasons like latency, security, and many more. This necessitates them to remain localized and remote connectivity. These scenarios can be found anywhere that distributed workloads and storage are present.
In these situations, application-driven networks replace present WANs with public cloud incorporations and connections to IoT, edge compute resources, and API gateways that do not interrupt other legacy WANs or add service provider overhead.
These solutions provide radical new concepts that incorporate networking systems with management capabilities and application deployment. The application architectures’ optimization that they provide is suitable for huge distributed applications across various environments.
APIs available in software-defined networking platforms can help build an application-driven network. The platforms help in managing policy and configuration updates from a centralized controller.
Enterprises, by rethinking network architectures and building networks, can free themselves from conventional network constraints, resulting in security, performance, and manageability improvements.
