WSO2 IoT Server comes as a composition of three components namely broker, core, and analytics. All of these components are WSO2 Carbon based products. Following are the minimum system requirements to run all the IoT components.



  • ~ 4 8 GB minimum (16 GB is recommended for a production environment.)
  • ~ 1024 MB heap size. This is generally sufficient to process typical SOAP messages but the requirements vary with larger message sizes and the number of messages processed concurrently.


  • ~ 1 5 GB, excluding space allocated for log files, mobile applications, and databases.

Environment compatibility

Operating Systems / Databases

  • All WSO2 Carbon-based products are Java applications that can be run on any platform that is JDK 8 compliant. Also, we do not recommend or support OpenJDK.
  • All WSO2 Carbon-based products are generally compatible with most common DBMSs. The embedded H2 database is suitable for development, testing, and some production environments. For most enterprise production environments, however, we recommend you use an industry-standard RDBMS such as Oracle, PostgreSQL, MySQL, MS SQL, etc. For more information, see Working with Databases. Additionally, we do not recommend the H2 database as a user store.
  • It is not recommended to use Apache DS in a production environment due to scalability issues. Instead, use an LDAP like OpenLDAP for user management.
  • For environments that WSO2 products are tested with, see Compatibility of WSO2 Products.
  • If you have difficulty in setting up any WSO2 product on a specific platform or database, please contact us.
