Network sprawl occurs when the number of networks in a company grows unchecked as more infrastructure moves to the cloud, and business units use more SaaS apps.

Understand Today's RealityUnderstand Today’s Reality

Recognize that hybrid IT is the new reality, and network sprawl may already be a problem in your organization.

Do Your HomeworkDo Your Homework

Research what cloud vendors and SaaS applications your enterprise uses and how it uses them. This could involve a lot of outreach to different departments and stakeholders.

Assess Performance RequirementsAssess Performance Requirements

Determine what performance requirements you need from these cloud and SaaS vendors—and whether they are living up to those needs. This may require digging into service-level agreements (SLAs).

Take ResponsibilityTake Responsibility

Acknowledge that internal IT managers ultimately have responsibility to ensure that the networks they own—and those of the cloud and SaaS vendors their organization relies on—perform well.

Understand the Trust ModelUnderstand the Trust Model

Take stock of how much trust there is in the cloud and SaaS vendors, and what trust model they follow when it comes to resolving issues: no trust, trust but verify or whole-hearted trust.

Gain Visibility Into NetworksGain Visibility Into Networks

You may never gain hands-on authority over cloud and SaaS vendors’ networks, so try the next best thing: visibility. Gain visibility by leveraging a network path-monitoring tool that shows a hop-by-hop analysis of critical paths and devices along the network delivery path, on-premise, cloud or hybrid IT environments.

Peel Back Network LayersPeel Back Network Layers

Use this visibility to peel back the layers of the vendors’ networks to see devices, latencies and route changes, and pinpoint issues with precision. This will establish a truthful relationship so that conversations are efficient and their help desks don’t toss the problems back to you.

Determine the ROIDetermine the ROI

Before migrating additional infrastructure to the cloud or relying on additional SaaS applications, carefully weigh the need, benefits and realistic ROI versus the risk of introducing more networks and infrastructure outside the IT department’s control.

Implement a Migration PlanImplement a Migration Plan

Implement a comprehensive migration plan, including a detailed timeline and expected performance based on the SLAs.
