4 Essentials for Delivering Secure Hybrid Cloud Networking
Making public cloud services simple, secure and effective
The growth of Infrastructure as a Service (IaaS) gives you new opportunities to shift workloads to third-party clouds temporarily to meet a variety of enterprise needs, from on-demand test and development environments to burst capacity delivered on a pay-as-you-go basis. This agility can come at a cost, though—the simple Internet connectivity typically used for this migration can limit security and performance significantly.
You shouldn’t have to choose between the security and performance of on-premise IT and the agility of a third-party cloud. Make sure your hybrid cloud strategy—and the cloud connectivity solution that supports it—provides for the four following elements.
1. End-to-end security
Moving workloads to the cloud over simple Internet connectivity with unproven security opens new, often unprotected entry points to your network. To protect your enterprise assets in transit, prevent threats from entering your enterprise network, and support compliance, you’ve got to ensure complete security for data in motion. One key measure is to go beyond the basic VPNs offered by most cloud protection and apply advanced encryption to protect your content as it moves between the enterprise and the cloud.
2. Optimized application delivery
The agility of the cloud doesn’t do you much good if it compromises performance, making it impossible to meet your SLAs or keep your users productive. Techniques like TCP optimization, compression and data deduplication can help you maintain acceptable performance across WAN links.
3. Deep application visibility
Hybrid cloud environments can make it more difficult to maintain, manage and control enterprise applications effectively. To support your business effectively, you need to be able to maintain deep visibility into how your applications are being used no matter how complex and dynamic they become. Application-level visibility and monitoring will help you find and fix problems more quickly as they emerge, and capture business intelligence to guide your strategy.
4. On-demand provisioning
Third-party clouds can be a valuable source of on-demand resources for people throughout your organization to help them meet time-sensitive or temporary needs. First, though, you’ve got to give them a simple way to tap into the cloud services they need, when they need them. By using L2 bridging to make the cloud network a natural extension of your own L2 network, you can make it easy to shift workloads to the cloud without having to re-architect applications.
