Fault Tolerant Network Design for Application High Availability
Enterprises are growing increasingly dependent on modern distributed applications to innovate and respond quickly to new market challenges. As applications grow in significance, the end-user experience of the application has become a key differentiator for most businesses. Understanding what kind of application performance the end-users experience, optimizing the infrastructure, and quickly identifying the source of any issues has become extremely critical.
The Modern Network framework puts the end-user experience at the forefront. It helps our customers provide the public cloud experience on-premise with an on-demand network that enforces secure connectivity and service objectives across on-premise and cloud environments. As applications become more distributed, the increased application resiliency and efficiency often comes at the cost of increased contention for shared resources. The dynamic nature of the network, device density, and the volume of data and transactions generated makes this even more challenging. Managing network complexity and simplifying network operations in such environments requires a well architected network with support for modern cloud concepts such as availability zones that provide fault tolerance. Similarly, effective network-level fault isolation requires the ability to create self-contained fault domains that facilitate network resiliency, disaster recovery and avoidance, and end-to-end root cause(s) analysis throughout the Continue reading
