Add IP-by-IP rate limiting to the HAProxy Kubernetes Ingress Controller. DDoS (distributed denial of service) events occur when an attacker or group of attackers flood your application or API with disruptive traffic, hoping to exhaust its resources and prevent it from functioning properly. Bots and scrapers, too, can misbehave, making far more requests than is reasonable.

In order to produce their masterpieces, artists like van Gough, Rembrandt, Picasso, and Monet painted with more than just one color. Being able to choose from multiple colors (not to mention an abundance of talent, inspiration, and creativity) is what allowed these artists to see their complete vision come to life on canvas. However, if you’re relying on a single set of data to troubleshoot network issues, it’s like you’re stuck painting with one color.

Load balancers play an important role in distributed computing. With load balancers, you can distribute heavy work loads across multiple resources, which allows you to scale horizontally. Since they are placed prior to computing resources, they need to endure heavy traffic and allocate it to the right resources fast. For this to happen, monitoring the health and performance of load balancers is key. In monitoring, visualization helps users to view various metrics quickly.
