EC2 Workloads at Scale Authors Edit this page AWS ECS gives you a way to manage a container service in AWS, but what if you want to run Kubernetes from within your AWS services? Elastic Load Balancers can distribute traffic among healthy containers. AWS Auto Scaling, meanwhile, offers a centralized place to manage configurations for a wider range of scalable resources, such as EC2 instances, Amazon Elastic Container Service (ECS), Amazon DynamoDB tables or Amazon Relational Database Aurora read replicas. EC2 provides great managed services and it manages the internal resources of instance like memory, storage, compute etc. They sound similar, but Amazon EC2 Auto Scaling and AWS Auto Scaling have different purposes. The architecture for Kubernetes, which relies on this experience, is shown below: As you can see from the figure above, there are a number of components associated with a Kubernetes cluster. So what exactly is EC2 Auto Scaling? etcd: This component stores configuration data which can be accessed by the Kubernetes masters API Server by simple HTTP or JSON API. Use Prometheus/Grafana to set up webhook when CPU utilization is over some %. Could an object enter or leave vicinity of the earth without being detected? You set defined metrics and thresholds that determine when to add or remove instances. Are witnesses allowed to give private testimonies? Together, Kubernetes and AWS Auto Scaling Groups (ASGs) can create magic in scalability, high availability, performance, and ease of deployment! 9.3 Pre-requisite configuration of controller node. AWS Auto Scaling introduced the concept of scaling plans, which use scaling strategies in order to manage resource utilization. To achieve HPA, you can do autoscaling in two ways. Is there any alternative way to eliminate CO2 buildup than by breathing or even an alternative to cellular respiration that don't produce CO2?
