Using Kubernetes on the public cloud is flexible and scalable for your application. AWS is one of the popular services in the public cloud industry. In this chapter, you will know what AWS is and how to set up Kubernetes on AWS along with the following topics:
When you run your application on the public network, you need an infrastructure such as networks, Virtual Machines, and storage. Obviously, companies borrow or build their own data center to prepare those infrastructures, and then hire data center engineers and operators to monitor and manage those resources.
However, purchasing and maintaining those assets need a large capital expense; you also need an operation expense for data center engineers/operators. You also need a read time to fully set up those infrastructures, such as buying a server, mounting to a data center rack, cabling a network, and then the initial configuration/installation of the OS, and so on.
Therefore, rapidly allocating an infrastructure with appropriate resource capacity is one of the important factors that dictates that success of your business.
To make infrastructure management easier...
We've discussed some AWS components that are quite easy to set up networks, virtual machines, and storage. Therefore, there are a variety of ways to set up Kubernetes on AWS such as kubeadm (https://github.com/kubernetes/kubeadm), kops (https://github.com/kubernetes/kops), and kubespray (https://github.com/kubernetes-incubator/kubespray). One of the recommended ways to set up Kubernetes is using kops, which is a production grade setup tool and supports a lot of configuration. In this chapter, we will use kops to configure Kubernetes on AWS. Note that kops stands for Kubernetes operations.
First of all, you need to install kops to your machine. Linux and macOS are supported. Kops is...
In this chapter, we have discussed public cloud. AWS is the most popular public cloud service and it gives the API to control AWS infrastructure programmatically. We can achieve automation and infrastructure as code easily. Especially, kops brings us to ultra-fast AWS and Kubernetes setup from scratch. Both Kubernetes and kops development are quite active. Please keep monitoring those projects, which will have more functionality and configuration in the near future.
The next chapter will introduce Google Cloud Platform (GCP), which is another popular public cloud service. Google Container Engine (GKE) is the hosted Kubernetes service that makes using Kubernetes much easier.
