Cisco ACI (Application Centric Infrastructure) is a vital part of modern data centers, allowing the deployment of Layer 4 to Layer 7 (L4-L7) services such as firewalls, load balancers, and other network devices. One of the crucial features of ACI is its ability to integrate these services using service graphs, which automate and optimize the flow of traffic between applications. This article explores the importance of L4-L7 services and service graphs, how they work, and why DCLessons is the right platform for mastering them.
Understanding Cisco ACI L4-L7 Services
In a traditional data center, network administrators manually configure L4-L7 services, which include security and traffic management devices. However, ACI’s policy-based approach eliminates this complexity by automating the deployment and configuration of these services. L4-L7 services in Cisco ACI are integrated with the application network profiles, simplifying deployment and improving efficiency.
How Service Graphs Work in Cisco ACI
A service graph in Cisco ACI defines the path that data packets take through various services like firewalls and load balancers. Essentially, it enables the flow of traffic to traverse through the desired network functions, improving security and performance without manual intervention.
• Example Use Case: A service graph can be created to route all inbound traffic through a firewall for inspection before reaching a load balancer, ensuring both security and high availability.
Why to Use Service Graphs in ACI
The need for service graphs stems from the growing demand for automating and streamlining application delivery and security. Service graphs help in:
• Automating service deployment
• Reducing manual configurations
• Ensuring consistent policy enforcement
• Enhancing scalability by integrating multiple L4-L7 services into the network fabric

How to Use L4-L7 Services in ACI
To use L4-L7 services within Cisco ACI, users define service graphs that describe the sequence of services through which traffic must pass. This can include firewalls, load balancers, and other appliances. The service graph is then associated with an application profile, allowing the ACI fabric to enforce policies and direct traffic automatically.
