<summary>Describe how would an architecture of production environment with large amounts of data would be different from a small-scale environment</summary><br><b>
|
||||||
|
|
||||||
|
There are several possible answers for this question. One of them is as follows:
|
||||||
|
|
||||||
|
A small-scale architecture of elastic will consist of the elastic stack as it is. This means we will have beats, logstash, elastcsearch and kibana.<br>
|
||||||
|
A production environment with large amounts of data can include some kind of buffering component (e.g. Reddis or RabbitMQ) and also security component such as Nginx.
