什么是云管理网络？
Cloud-managed Networking Explained
- 网络能力和资源累积量ted in a public or private cloud platform, managed in-house or by a service provider, and available on demand.
- Today’s highly mobile users and applications demand the performance, security, and management provided by cloud networking flexibility and scale.
- Cloud-managed networking also offers IT efficiencies and cost savings for office spaces, schools, work from home environments, and healthcare and public venues.
Why cloud-managed networking?
现代云基础设施提供了一个新的敏捷性，很难通过传统的内部部署模型来完成。对于许多组织来说，利用虚拟服务和基础架构而不是购买和维护物理管理设备，更有意义。
Cloud-managed networking provides the following advantages:
- Faster rollout and adoption of new software and feature updates
- Fewer network devices required in branch offices, in addition to savings in the data center
- 扩展计划和实施失败或冗余服务
- Increased security that leverages the expertise of cloud providers and their network infrastructure vendor
云管理网络如何推动创新？
The popularity of cloud computing opened doors that weren’t possible with siloed, on-prem infrastructure and software. It’s easier to gather data from a larger number of sources, support a wider audience without adding physical resources, and create a vast data lake that provides for more granular and meaningful analytics. The same is true for cloud-managed networking.
- All network infrastructure under management can feed telemetry into a single data lake for better analysis.
- AI和机器学习服务可以识别异常模式以帮助排除故障。
- AI comparisons across sites can guide organizations on how to optimize their networks for performance gains.
- 可以更轻松地共享有关新的IOT设备的信息，增强网络安全性。
Benefits of cloud-managed networking
The following table compares the benefits of on-premises and cloud-managed networking.
| Benefits | On-premises | Cloud Networking |
|---|---|---|
| 规模 | 依靠硬件购买，机架空间，冷却，电源等。 |
Only requires licensing for on-premises APs, switches, and gateways for cloud management. |
| Microservices flexibility | Legacy software principles are common. You must download updates and fixes and adhere to fixed release cycles. |
Software is updated when needed, and features are added without affecting other services or release cycles. |
| Data lake usability | Constrained by the size of your network and storage within deployed appliances. |
Volume and variety of data scales to your vendor’s install base. |
| AIOps and troubleshooting | Limited due to size of usable data. |
故障排除洞察可用于Wi-Fi，有线，WAN，安全性和最终用户体验。基于新的和相关数据不断更新模型。问题更快地解决了。 |
| AIOps and optimization | Limited due to size of one customer’s data lake and the variety of usable information. |
Leverages data across customer’s site and similar (anonymous) sites to highlight where specific sites are under-performing. Proactive approach avoids issues. |
| Security | 需要外部访问，防火墙规则，每个管理员角色访问，维护软件等。 |
Requires outside access, but cloud providers and infrastructure vendors maintain strict security practices. Software patches are implemented as needed. Data lake can support new services such as client profiling, behavior analytics, and more. |
| IT资源和技能 | Maintenance and training are a constant point of contention. |
IT can focus on delivering new services. |
