A Kubernetes Ingress Controller is the combined version of Ingress, [Load Balancer](https://konghq.com/blog/engineering/api-gateway-vs-load-balancer)Load Balancer, and Gateway API. Using the set of rules and restrictions from the Ingress, the Kubernetes Ingress controller can balance the load of traffic both into and between the [Kubernetes](https://konghq.com/blog/learning-center/what-is-kubernetes)Kubernetes cluster. Using the components of a Gateway API like a reverse proxy, the Ingress Controller can also provide security and encryption to the location of the Kubernetes cluster. Kubernetes Ingress Controller is an all-in-one tool that can utilize the beneficial aspects of various Kubernetes components.

While the convenience of Kubernetes Ingress Controller is a huge incentive, there are a handful of specific use cases where it really shines. Similar to the convenience aspect, it centralizes and simplifies Ingress management for the user. It can monitor and direct all traffic moving in or out of a cluster, assuming roles of [Kubernetes Ingress](https://konghq.com/blog/learning-center/what-is-kubernetes-ingress)Kubernetes Ingress and egress.
The primary responsibilities of a Kubernetes Ingress Controller include:
While the many components of Kubernetes Ingress Controllers can be done individually, the main benefit is that it conveniently groups all those features into one control panel. Since everything is all monitored in one place, it’s easy for the user to see real-time metrics on API usage, traffic, and more. For new members, the intuitive interface is quite easy to learn, so there’s no more steep learning curve from managing multiple applications with Kubernetes Ingress Controller.
Additional benefits include:
With the many options for Kubernetes Ingress Controllers out there, it’s important to understand what specifically to look for when choosing the best fit for the user's needs. Depending on the amount of traffic being brought to a service, it’s crucial to find an Ingress Controller that’s able to deal with traffic both high and low. Also, based on prior level of expertise, having an Ingress Controller that’s capable of synthesizing and simplifying API and security information for the user may be of significant value.
To look toward the future, users want to choose an Ingress Controller that will continue to evolve and adapt as the organization’s needs change. Some Ingress Controllers specialize in commercial usage, while others may be more catered towards open-source projects or casual services. Ultimately, your services and information are indispensable. The ability to implement the correct API for security and encryption is a key feature.
Here are some key factors to consider when selecting an Ingress Controller:
[Kong Ingress Controller](https://konghq.com/products/kong-ingress-controller)Kong Ingress Controller is one of the many Kubernetes Ingress Controllers out there, but what sets it apart from the others?
