What is Cloud-managed Networking?
Cloud-managed Networking Explained
- Network capabilities and resources are hosted 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?
Modern cloud infrastructure provides a new level of agility that is difficult to accomplish with a traditional on-premises model. For many organizations, it makes more sense to take advantage of virtual services and infrastructure rather than buying and maintaining physical management appliances.
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
- Expansion plans and implementation of fail-over or redundancy services
- Increased security that leverages the expertise of cloud providers and their network infrastructure vendor
How is cloud-managed networking driving innovation?
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 and machine learning services can identify abnormal patterns to aid in troubleshooting.
- AI comparisons across sites can guide organizations on how to optimize their networks for performance gains.
- Information regarding new IoT devices can be more easily be shared, enhancing network security.
Benefits of cloud-managed networking
The following table compares the benefits of on-premises and cloud-managed networking.
Relies on hardware purchases, rack space, cooling, power, etc.
Only requires licensing for on-premises APs, switches, and gateways for cloud management.
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.
Troubleshooting insights are available for Wi-Fi, wired, WAN, security, and end-user experience. Models are continuously updated based on new and relevant data. Issues are resolved more quickly.
|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.
Requires outside access, firewall rules, access per admin role, maintaining software, etc.
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 resources and skills|
Maintenance and training are a constant point of contention.
IT can focus on delivering new services.
