    - DEX Installation
      This topic provides a detailed sequence of steps required to install all BigFix DEX components. The installation must follow the order listed to ensure successful integration and configuration of all dependent services.
      - DEX Capacity Plan
        Capacity Planning is the proactive practice of checking your IT environments' current endpoint usage and forecast when they will run out of resources. The main objective is to prevent performance drops or system crashes before they happen.
      - DEX Deployment Requirements
        This section outlines the hardware, network, and storage specifications required to deploy DEX.
      - DEX Prerequisites
        Before installing DEX, the following set of prerequisites must be met:
      - Analysis
      - Fixlets
      - System support and requirements
        This topic provides information about the system requirements for DEX.
      - BigFix UI Installation
        This topic provides an overview of the BigFix UI Configuration Manager setup process and describes the sequential steps required to complete the configuration of your BigFix UI.
      - DEX Installation
        This topic provides a detailed sequence of steps required to install all BigFix DEX components. The installation must follow the order listed to ensure successful integration and configuration of all dependent services.
      - BigFix Self-Service Application
        The BigFix Self-Service Application (SSA) is a client-side interface that empowers endpoint users to install software, accept administrative actions, and review deployments without requiring local administrator privileges.
      - Firewalls configuration
      - BigFix UI Command line DEX configuration
        To configure the BigFix UI to show the DEX application to the users with 'DEX dashboard' privileges, you can use the BigFix UI command line to configure DEX.
    - Configuration
      BigFix DEX provides four configuration Fixlets, one for each DEX component, to support post-installation configuration and reconfiguration.
    - Upgrade
      The upgrade Fixlets are available for each of the four DEX components, which internally refers to the same directory path where the installation was previously performed.
  - Knowing BigFix UI
    BigFix UI is a unified interface that consolidates multiple BigFix capabilities into one modern application. It provides IT operations and security teams with a centralized workspace to manage endpoints, remediate vulnerabilities, and generate reports.
  - Integrations available with DEX
    The Service Now, Remote Control and Historical data integration are available using the APIs. For information on the respective areas, refer to their documentations.

DEX Deployment Requirements

This section outlines the hardware, network, and storage specifications required to deploy DEX.

Server & Database Requirements

The system requirement for DEX server is as same as the BigFix root server, with an increase in the database capacity for time series historical data.

1 Gbps+ NIC
1K IOPS at 2ms storage at least

Software requirements

BigFix Platform versioon 11.0.6 or later is required to use the BigFix UI.

Windows Component requirements

The “+” before the required capacity means the value is to be added on top of the OS, the BigFix Platform requirements (where applicable), and the other components’ requirements.

For the POC, the whole machine where the BigFix Root Server with its database, the BigFix UI and the DEX Server with its MSSQL database reside is sized.


Use case	Components	CPU	RAM	Disk
POC	all co-located with the RootServer	8 vCPU	22 GB	250 GB
50K	DEX RS Plugin	+4 vCPU	+8 GB	+150 GB
	DEX BackEnd	+6 vCPU	+24 GB	+150 GB
	DEX MSSQL	+4 vCPU	+8 GB	+500 GB
	BigFix UI	+4 vCPU	+4 GB	+100 GB

Linux Node requirements (ClickHouse DB)

These specifications represent the sizing for the full dedicated Linux node hosting the ClickHouse time-series database.


Use case	CPU	RAM	Disk
POC	4 vCPU	16 GB	200 GB
50 K	8 vCPU	28 GB	1 TB

BES Relays

The relays are not required for Proof of Concept (POC) setups or small test environments. For production environments scaling up to 50,000 devices, use the following framework:


Use case	CPU	RAM
50 K	4 vCPU	8 GB

GB = OS + 3GB (BigFix binaries + logs) + 2GB (Default Cache) + Extended Cache (if configured) + 300 MB/site (site cache for relay)

Note: It is recommended to apply the _BESRelay_PostFile_PassThrough setting to '1' on every BigFix relay as part of the initial DEX configuration.
