ACI: Addressing The Changing Landscape
Industry shifts are redefining IT at all levels. On-premise IT consumption models are shifting to cloud-based services. IT as a service (IaaS) is supplanted by applications as a service. Separate development and operations are moving toward integrated development and operations (DevOps). Box-centric management models are migrating to application-centric management.
Business agility requires application agility, so IT teams need to provision applications in hours instead of months. Resources need to scale up (or down) in minutes, not hours.
Traditional approaches take a siloed operational view, with no common operational model between the application, network, security, and cloud teams. A common operational model delivers application agility, simplified operations, assured performance, and scale.
The Solution: An Application-Centric Approach to Managing Your Infrastructure
Application Centric Infrastructure (ACI) is a holistic architecture with centralized automation and policy-driven application profiles. ACI delivers software flexibility with the scalability of hardware performance.
Cisco ACI consists of:
- The newÂ Cisco Nexus 9000 Series Switches
- A centralized policy management andÂ Cisco Application Policy Infrastructure Controller (APIC)
- AÂ Cisco Application Virtual Switch (AVS)Â for the virtual network edge
- Software and hardware innovations
- Integrated physical and virtual infrastructure
- An open ecosystem of network, storage, management, and orchestration vendors
Key characteristics of ACI include:
- Simplified automation by an application-driven policy model
- Centralized visibility with real-time, application health monitoring
- Open software flexibility for DevOps teams and ecosystem partner integration
- Scalable performance and multi-tenancy in hardware
The future of networking with ACI is about providing a network that is deployed, monitored, and managed in a fashion that supports DevOps and rapid application change. ACI does so through the reduction of complexity and a common policy framework that can automate provisioning and managing of resources.
