Application-centric infrastructure

(also application-focused infrastructure)

Application-centric infrastructure definition

An application-centric infrastructure (ACI) represents a class of network architectures where the steering of network operations, efficacy, and defense revolves around discrete applications or services instead of the physical network fabric. It entails a comprehensive, start-to-finish integrated system with streamlined application deployment and management.

Application-centric infrastructure examples

  • Cloud services: ACI can automatically adjust resource allocation based on application needs in a cloud environment, making resource usage more efficient.
  • Data centers: Data centers use ACI to streamline network provisioning and ensure application performance.

Advantages and disadvantages of application-centric infrastructure


  • Efficiency: ACI allows for quick deployment and easier management of applications, reducing operational overhead.
  • Agility: It fosters a more responsive network, automatically adjusting resources to meet application demands.
  • Security: ACI enhances security through fine-grained, application-level policies.


  • Complexity: Transitioning to an ACI requires a significant shift in how the network is managed and can be complex to implement.
  • Cost: The initial costs for setting up an ACI, including hardware and software components, can be high.

Using application-centric infrastructure

  • When implementing ACI, ensure the network, security, and applications teams work together for a seamless transition.
  • Train the team to handle the new infrastructure, focusing on application performance and security rather than physical network elements.
