Achieve Cloud Networking with the VXLAN Network Solution

Posted on Oct 20, 2023 by

Networking plays a pivotal role in computing, connecting devices, integrating systems across different locations, and ensuring secure data transfer. However, with the emergence of cloud computing, traditional networking falls short of meeting the scalability, reliability, and security demands of organizations. This has led to the evolution of cloud networking, which leverages virtual networks to enable resource sharing and address the limitations of traditional networking. This article will introduce knowledge about cloud networking and how the FS solution achieves cloud networking.

What Is Cloud Networking?

Cloud networking refers to an IT infrastructure where networking processes, resources, and capabilities are hosted in the cloud (public, private, or hybrid) and are accessible on demand. It encompasses a range of components such as virtual routers, load balancers, switches, bandwidth, virtual firewalls, and network management software. At its core, cloud networking facilitates internet accessibility for applications and establishes connectivity between workloads, services, and data centers. Moreover, it enables organizations to test and deploy new services or updates while safeguarding against malicious threats.

How Does Cloud Networking Work?

Cloud networking architectures are constructed using cloud-based services, typically offering centralized management and control. The inner workings of a cloud network, however, differ depending on the type of cloud network and whether the network is hosted on a private, public, or hybrid cloud.

Cloud Network

For example, with a private cloud, architects have more flexibility when it comes to the overall design. This is because the cloud provider fully manages the underlying hardware and software on which the cloud is built.

For public clouds, customers can control and manage networking only in infrastructure as a service (IaaS) deployments. With software as a service (SaaS) and platform as a service (PaaS), the customer has no control over network functions, as they're fully managed by the service provider. If organizations need to configure aspects of their network in a public cloud, IaaS is their best option.

Cloud Services

An organization may instead opt to operate in a hybrid cloud architecture. That means some applications, data, and services reside on-premises, while others are moved to an IaaS provider. The ideal scenario for organizations with this method would be to mimic the network Internet Protocol (IP) space, policies and procedures already established in their own data centers.

Achieve Cloud Networking with the VXLAN Network Solution

Over time, corporate data center resources evolved and moved from on-premises mainframes to the cloud. The added benefits of hosting data centers in the cloud include security, uptime, scalability and the freedom of not having to worry about on-premises deployments. Because of these benefits, more organizations began moving to the cloud and deploying cloud networking in data centers. Recently, FS has provided a cloud data center VXLAN network solution for customers, let's have a detailed look at this solution.

Understanding Cloud Data Center VXLAN Network Solution

The Cloud Data Center VXLAN Network Solution is a comprehensive networking solution designed specifically for cloud networking, which leverages the Virtual Extensible LAN (VXLAN) technology to enhance connectivity, scalability, and security within cloud networks. By encapsulating Layer 2 Ethernet frames into UDP packets and transmitting them over Layer 3 networks, VXLAN enables the extension of Layer 2 domains across distributed environments. The FS.COM solution provides detailed guidance, including network architecture, equipment selection, and configuration best practices, to help organizations implement VXLAN effectively in cloud data centers. With this solution, customers can achieve improved network performance, simplified management, and enhanced security in their cloud networking infrastructure.

Architecture of Cloud Data Center VXLAN Network Solution

The Cloud Data Center VXLAN Network Solution leverages a robust architecture and a range of high-quality products to enable efficient and secure networking in cloud environments. The solution utilizes a scalable spine-leaf architecture, where spine switches NC8400-4TH provide high-bandwidth connectivity and leaf switches N5860-48SC connect to servers and storage devices. This architecture ensures optimal performance and flexibility for cloud networking. Here is the topology of this solution.


Key Benefits of Cloud Data Center VXLAN Network Solution

The VXLAN network of cloud data centers was successfully established for customers, and more efficient data center network architecture, more stable application services, more flexible business expansion, and simpler network management.

  • Converged Ethernet: Cloud transformation aims to reduce construction costs, improve cost-effectiveness, unify network operations through a fully converged Ethernet network, consolidate resources, and increase resource utilization rates.

  • Network Virtualization: It supports virtualized business, the hardware overlay meets high-performance network requirements. Through an SDN controller, it can be connected to the cloud platform to support network resource pooling.

  • Automated O&M: It supports the Ansible platform, which can achieve automated O&M, reduce and simplify the heavy manual operations required for large-scale data center equipment deployment, and greatly improve operational efficiency.

  • Business Continuity: Highly reliable network, fully redundant load, single network equipment, link failure does not affect business operation, servers support dual uplink redundancy.

  • Network Scalability: Service units are deployed as modules with PODs, supporting standardized and rapid expansion to meet ultra-large-scale service node access.
