AWS devops: ElasticSearch at AWS with terraform and ansible

The course consists of 5 main modules.

The first one is about how to deploy ES as an AWS service, which is called OpenSearch. Here I will tell you about interesting OpenSearch pitfalls that I discovered during my commercial practice. And believe me, you will not find that information in the AWS documentation. You will get a ready-terraform module for deploying the Opensearch cluster, and we will analyze it step by step together.

In the 2nd part, I will show how to deploy an ES cluster at ECS (Elastic Container Service). And again, we will use the terraform modules for that. I will show you why you can't use Fargate in that case and how many problems should be resolved to deploy ES at ECS.

The next course section is about how to deploy ES at EC2 instances using Docker Swarm. I will prove to you that it is the easiest and, at the same time the cheapest way to deploy ES at almost any cloud for most small and middle companies with a steady growth pattern. You will get ready Terraform modules that will allow you to prepare AWS infrastructure and Ansible modules for deploying the HA ES cluster upon it.

The 4th part is devoted to the autoscaling possibilities of ES clusters using different deployment approaches. We will talk about what we really can autoscale, when we can use it, and what big limitations we have in the case of working with ES.

The 5th module is devoted to the theory. If you are already familiar with ES cluster conceptions and everything that is related to shards and ES performance - then you can skip it. But if not, that is the place where you have to start from.
