SOC deployment using Elasticsearch, TheHive, MISP and Coretex

A cyber security expert with experience in security operations centre deployment is needed to help deploy our SOC using elasticsearch, theHive, misp, and cortex. Four digital ocean droplets are created for each tool, with all four tools successfully installed separately. At this stage, we require help integrating all four tools to work as one, i.e., connecting misp and cortex to theHive and connecting theHive to elasticsearch.
Some of the issues we’ve encountered during the process are as follows:
• Unstable Kibana: With a successful installation and configuration, Kibana serves as the web interface for elasticsearch. However, running it as a service can result in the tool being unstable when stopped and restarted and shows the error message “Kibana server is not ready yet.”
• Cortex Configuration Issues: Cortex throws several errors relating to configuration, such as “Connection Closed” and “unable to find valid certification path to requested target.”
• Issues with integrating theHive to elasticsearch
Some of the steps we’ve completed successfully are as follows:
• Installation and configuration of Elasticsearch with Kibana.
• Installation and configuration of theHive and Cassandra.
• Installation of a working MISP.
• Installation of Cortex.
• Generated a Keystore for Cortex.
Our objectives:
• Install required tools (Elasticsearch, theHive, MISP, Cortex).
• Configure the tools.
• Integrate all tools.
• Set up endpoints for monitoring.
Project Scope.
• Type of tools: Opensource
• Server: Digital Ocean Droplets

Please reply telling me what experience you have with the above tools.
