# Checklist: Creating an On-premises Deployment

Use the following checklist to start an on-premises deployment. The most of these tasks are required regardless whether you choose to use the ArcSight Installation Tool or the manual process. If you choose the manual route, there will be a more comprehensive checklist to guide you. Be sure to return to this checklist after installing OMT and deploying the capabilities as there are several post-installation steps to complete.

To know your storage options before you install the ArcSight Database, review Understanding Object Storage Options for the ArcSight Database

Perform the tasks in the listed order.

| Complete the Planning Checklist | Checklist: Planning to Deploy the Platform
| Decide whether to use the ArcSight Platform Installer tool or the manual process. | Choosing Your Installation Method
| Review the guidance on how EDR and SysOps applications might affect the installation process | Caution for EDR Applications
| (Conditional) If you plan to install the ArcSight Database, review your options for S3-compatible object store technologies | Understanding Object Storage Options for the ArcSight Database
| (Conditional) If you plan to use only the ESM Command Center, install ESM on the same server where you will deploy ArcSight Platform | Deploying ArcSight Platform and ESM on the Same Server
| (Conditional) If you need an Internet connection, and you already specified a proxy server for http and https connection, then you must correctly configure `no_proxy` | Configuring Proxy Settings
| Ensure that host name resolution through Domain Name Services (DNS) will work across all nodes in the cluster | Configuring DNS Settings
| To maintain state information about the infrastructure and to store other pertinent data, ensure that all nodes in the Platform Kubernetes cluster will be able to use NFS storage | Creating the NFS Shares
| To evenly distribute resources, disable swap space | Disabling Swap Space
| Ensure that you have the latest installation files | Downloading the Installation Packages for an On-Premises Deployment
| To begin the installation, select ONE of the following methods: • (Recommended) For an automated deployment, use the ArcSight Platform Installer. OR • If the automated installation process will not work for your environment, use the manual deployment option. | • (Recommended) Using ArcSight Platform Installer for an Automated On-Premises Installation OR • Performing a Manual Deployment
| Complete the deployment process | Post-deployment Configuration
| Configure your SmartConnectors and Collectors as producers of events into Transformation Hub, as well as configure event Consumers such as Logger and ESM | Integrating the Platform Into Your Environment
