How does Cisco ACI work - Introduction to Cisco ACI (Application Centric Infrastructure) was a breakthrough under Software-Defined Networking (SDN) solution for Data Centers.  

The application-optimized approach in ACI made data center configuration activity efficient, reliable, and seamless by specifically eliminating the need to configure each router and switch manually.  

This effective networking device configuring method was necessary for enterprises because traditional SDN infrastructure was too focused on complex networking modules and, therefore, missing the essential functionality.  

So, after 2013 – the year Cisco ACI Solution was introduced- the complete networking landscape changed. Managing networks and adapting to new models became an essential skill for network professionals, and that's why people in the networking field are expected to be well versed with this technology.  

Keeping these requirements in focus, there has been a steady rise in the number of courses and training videos about learning ACI. But before you jump to such online resources, you must know some valuable things about Cisco ACI training.   

So, today we will explore how does Cisco ACI works, its benefits, and the must-known facts about the ACI training.   

But before that, let's start with what is Cisco Application Centric Infrastructure and why it is necessary for exploring SDN solutions.    

What Is Cisco Application Centric Infrastructure?

Cisco's ACI (Application Centric Infrastructure) is a policy-driven, tightly coupled solution made by the industry leader, integrating hardware and software. Using the latest Cisco Nexus 9000 family of switches as the hardware, ACI's software and integration points comprise Data Center Policy Engine, Additional Data Center Pod, and Non-directly Attached Virtual and Physical Leaf Switches.   

ACI (Cisco Application Centric Infrastructure) may seem like something that enterprise data centers have been using for the past few years, but it's pretty different. The things that make it different are its management, policy framework, and protocol. It has become the leading solution in the industry as it offers high software flexibility and scalability of hardware performance.   

These benefits have led to an increased demand for experts who know how to navigate and use the ACI (Cisco Application Centric Infrastructure) infrastructure. Due to this, webinars, training videos, and online courses about ACI have become very useful for professionals.  

So, if you being a Network Engineer, have ever wondered, is Cisco ACI worth it? Then the answer is definitely YES!  

How Does Cisco ACI Work?

Cisco ACI, the industry-leading SDN solution, combines the best software and hardware capabilities elements and facilitates application agility and data center automation.  

The hardware for ACI is the Cisco Nexus 9000 family of switches. Similarly, ACI's software and integration points include components like Data Center Pod, Data Center Policy Engine, and Non-Directly Attached Virtual and Physical Leaf Switches. Also, the use of Cisco's Application Virtual Switch (AVS) can push down policies to virtual switches.  

In a leaf-spine ACI fabric, Cisco provisions a built-in Layer 3 Internet Protocol (IP) mechanism that supports equal-cost multi-path (ECMP) routing between two endpoints in a network. Also, one of the major features of Cisco ACI is overlay protocols, such as the Virtual Extensible Local Area Network (VXLAN), which allow any workload to exist anywhere in the network.  

Overlay protocol allows the data fabric to have machines, either physical or virtual, in the same logical network even when layer two domain and Layer 3 routing is executed that too without causing a conflict between them.  

The ACI fabric supports VLAN, VXLAN, and NV-GRE, making it easier for Network Engineers to host a functional network or domain as per their requirements.  

Now talking about the management perspective, the central SDN controller for ACI is APIC (Application Policy Infrastructure Controller), which manages and configures the policy on each of the switches in the ACI fabric. They also deploy and re-deploy hardware, as needed, by using a stateless computing model, making network engineers do not have to configure devices manually.  

Engineers can integrate third-party services for advanced security, load balancing, and monitoring on ACI fabric.   

Vendors and products like SourceFire, Embrane, F5, Cisco ASA, and Citrix can be integrated natively into the ACI fabric.   

ACI can also integrate with different types of cloud environments to make them more functional and impactful.  

This is how Cisco ACI works and streamlines your crucial components such as,   

  • Managing data security  
  • Balancing workloads and  
  • Monitoring progress.  

Now, you have learnt how does Cisco ACI works but it’s also crucial to understand how Network Engineers can benefit from Cisco ACI training.
