Hello, I have a lot of "strange"questions about the elasticsearch requirements for server. I want to use Elasticsearch for ELK Stack.The application produces around 4 GB a day. So that is not so many datas. The first question: Do I have to have in cluster master node and data node ? Or Can I have only for example master date and nothing else. Second question: How much space do I need to have on the server for this small data . Sorry, that I have so strange questions 😕 Thank you !!! ---

May I suggest you look at the following resources about sizing: [https://www.elastic.co/elasticon/conf/2016/sf/quantitative-cluster-sizing](https://www.elastic.co/elasticon/conf/2016/sf/quantitative-cluster-sizing) > **[How many shards should I have in my Elasticsearch cluster?](https://www.elastic.co/blog/how-many-shards-should-i-have-in-my-elasticsearch-cluster)** > > If you are looking for practical guidelines around how many indices and shards to have in your cluster, this blog post will help you avoid common pitfalls. https://www.slideshare.net/slideshow/embed_code/key/vR0XKDq4TGa77z And [https://www.elastic.co/webinars/using-rally-to-get-your-elasticsearch-cluster-size-right](https://www.elastic.co/webinars/using-rally-to-get-your-elasticsearch-cluster-size-right) ---

You need at least one data and master node in a cluster so it makes sense to start with the default configuration rather than using dedicated node types from the start. ---

4 GB a day because of the regulate 50 % I need 8 GB for heap size, right? What i stil dont understand is; How much data should I have to send to Master Data and to Data Node I understood the difference between Master node and Data node . Thank you in advance ---
