Designing Fault Tolerant Data Centers of the Future

These words send chills down the spines of network administrators. When business apps go down, business leaders are not happy. And the cost can be significant.

Recent IDC survey data shows that enterprises experience two cloud service outages per year. IDC research conservatively puts the average cost of downtime for enterprises at $250,000/hour. Which means just four hours of downtime can cost an enterprise $1 million.

To respond to failures as quickly as possible, network administrators need a highly scalable, fault tolerant architecture that is simple to manage and troubleshoot.

What’s Required for the Always On Enterprise

Let’s examine some of the key technical capabilities required to meet the “always-on” demand that today’s businesses face. There is a need for:

Granular change control mechanisms that facilitate flexible and localized changes, driven by availability models, so that the blast radius of a change is contained by design and intent.

Always-on availability to help enable seamless handling and disaster recovery, with failover of infrastructure from one data center to another, or from one data center to a cloud environment.

Operational simplicity at scale for connectivity, segmentation, and visibility from a single pane of glass, delivered in a cloud operational model, across distributed environments—including data center, edge, and cloud.

Compliance and governance that correlate visibility and control across different domains and provide consistent end-to-end assurance.

Policy– driven automation that improves network administrators’ agility and provides control to manage a large-scale environment through a programmable infrastructure.
