Cloud networking services offer fast delivery, lower costs, and more time. Explore features of the best solutions now. 

Cloud networking is all about removing internal concern for all or part of the networking function by farming it out to a third party. Done right, the advantages are faster delivery of content, lowered costs, and more time available for IT resources. That makes it a popular option for content providers, ecommerce operations, SaaS providers, and those already taking advantage of cloud services.

The appeal is simple, and similar to that of cloud services in general. Why continue to buy, maintain, and service routers, bandwidth, firewalls, and management software when someone else can take care of it? 

The basic idea is for the cloud networking provider to help the user establish cloud-based networking services for areas such as centralized management, wider geographical availability and distribution, traffic monitoring, and lower latency. By piggybacking onto cloud networking services from a global provider, the organization can increase service quality across a wider area. Providers also bundle security services and load balancing into many of their offerings. 

Use Cases 

There are many different use cases for cloud networking: 

  • Speed: Cloud networking can drive agility, boost time-to-market, and speed up the deployment of networking expansion initiatives. 
  • Scale: Organizations can provide a stable, global network that can scale to many more users than internal IT teams can easily cope with. 
  • Redundancy: The cloud makes it easier to adopt a multi-data center strategy by leveraging network cloud resources from many cloud service providers.
  • Deferring capital costs: Organizations with outdated network equipment in need of a refresh can move costs from Capex to Opex by opting for cloud-based networking. 
  • IT prioritization: With IT teams steadily shrinking, organizations want their remaining resources to concentrate on strategic objectives. Putting out networking fires or maintaining the networking infrastructure is rarely going to meet the cut when it comes to key strategic elements.

Cloud Networking Service Selection 

Those in the process of selecting cloud networking services, should pay attention to several key areas: 

  • Current cloud service providers: Those considering cloud networking should first review the cloud services providers they are already using to see if their networking services fit the bill. 
  • Operational consistency across clouds: Few, these days, manage to standardize on only one cloud platform. Therefore, check how the intended platform will interoperate with other cloud resources.
  • Geographical extent: If all users are within one country or one region, why pay more for a global network? And on the other side of the coin, those needing to provide global networking availability should avoid more localized cloud networking resources. 
  • Visibility: Some providers are better than others on providing visibility into networking resources. If the network is likely to experience major spikes or is integral to revenue generation, more visibility and management are required, not less.  
  • Security: Pay close attention to the security services that come with the network. Consistent and comprehensive security must go hand in glove with cloud networking resources. 
  • Scalability: Some cloud networks scale up and down easier than others. If the organization may experience spikes in demand, the ability to auto-scale rises in importance. 
  • Billing: Watch out for hidden costs or complicated pricing and tiers that make it difficult to predict monthly bills. 
  • Programmability: Cloud networking is all about automating routine and rote tasks to deliver reliably consistent outcomes. Ask the vendor about repeatable design patterns that can be reused in data centers, campus networks, and across multiple cloud providers.  
  • Reliability: The system design must embrace individual unit failures and be capable of recovering automatically from point outages without compromising overall availability.
