| 19 | |
| 20 | The SDC architecture uses the Jetty server as an application server. |
| 21 | |
| Idan Amit | 1aa38a4 | 2017-11-02 16:53:49 +0200 | [diff] [blame] | 22 | - The **Jetty front end**: |
| kaihlavi | e9135d2 | 2019-05-17 14:54:25 +0300 | [diff] [blame] | 23 | - supplies the static content of the web pages and all the resources that are required by the GUI |
| Idan Amit | d90aab6 | 2017-11-02 13:42:29 +0200 | [diff] [blame] | 24 | - serves as a proxy for the REST API requests coming from the GUI |
| 25 | |
| 26 | Every request originating from the GUI is passed to the Jetty front-end server before it is executed. |
| 27 | |
| kaihlavi | e9135d2 | 2019-05-17 14:54:25 +0300 | [diff] [blame] | 28 | - The **Jetty back end** contains all the logic for the SDC. |
| Idan Amit | d90aab6 | 2017-11-02 13:42:29 +0200 | [diff] [blame] | 29 | |
| 30 | SDC uses two storage components: Elastic Search(ES) and Cassandra |
| 31 | |
| Idan Amit | 1aa38a4 | 2017-11-02 16:53:49 +0200 | [diff] [blame] | 32 | - **Elastic Search** is used to index the auditing data received from different operations in the SDC. |
| Idan Amit | d90aab6 | 2017-11-02 13:42:29 +0200 | [diff] [blame] | 33 | |
| Idan Amit | 1aa38a4 | 2017-11-02 16:53:49 +0200 | [diff] [blame] | 34 | This information can then be analyzed with Kibana. The **Kibana server** enables statistical analysis of the operations done, according to the business logic. |

| Satyaki Mallick | 56309f4 | 2018-10-16 18:20:53 +0530 | [diff] [blame] | 36 | - **Cassandra** is used to store audit data, artifacts and data model objects. |
