1 Installation Requirements 

1.1 Hardware Requirements 

DataMesh Cloud Services (DCS) can be installed on:

• Public Cloud
• Private Cloud
• On-Premise Servers 

For clients using on-premise servers, DCS can be installed on either bare metal servers or virtualized servers. 

–	Trial / Demonstration	Small Office	Big Office or multiple Offices	Customized or SaaS based
No. of Supported Clients	<= 2	<= 10	<= 50	>50
No. of Servers	1	1~2	1~5	Many
Server Type	PC / Workstation	Workstations / Rack Servers	Rack Servers / Virtualized Servers / Private Cloud / Public Cloud	Public Cloud
Hardware Requirement	Server with 4C/8G Disk 40GB	Servers with 16C/64G 200G Disk	Servers with 16C/64G 500G Disk	Servers with 16C/64G 500G Disk
File Storage	On Server	On Server	On Server or Object Storage	Object Storage
3D-Model Accelerating Service	No	Optional	Optional	License required

* xC / yG means server with x vCPUs and yGB RAM. 

* Object Storage, like Azure Blob Storage or Amazon AWS S3, is recommended for clients with Internet access or need work remotely. 

* Dedicated storage device with RAID, like NAS or Disk Arrays, is recommended for file storage and used as backend of DCS Storage Service for on-premise deployment, this service should be mounted on server as a directory. 

* Production servers, on-cloud or on-premise, bare metal or virtualized, should be directly reachable by each other. 

* 3D-Model Accelerating Service, DCS License required, Unity License Required, Windows PC with Unity required. 

* For on-premise or private cloud deployment, users may need VPN to access DCS from Internet. 

1.2 Software Requirements 

Operating System 

Ubuntu 18.04 is tested and recommended for production usage, Windows is also supported for trial or small offices. 

Application Softwares 

• DataMesh Cloud Services (DCS) 
• DataMesh Manager (DMM) 

DataMesh Manager is the management system for DCS installation, services managements. 

Server / Runtime softwares 

• Java
• Nginx
• MySQL 
• MongoDB 
• Redis, optional, not available on Windows 
• ActiveMQ, optional for trial 
• Apache ActiveMQ Artemis or other MQTT Broker, optional for trial 

2 Installation 

2.0 Before Installation 

For servers with Internet Access
