# System Administrator/DevOps Engineer Profile: System Administrator Squirro offers its products as [SaaS](../a-z/industry-glossary.md#term-SaaS) solutions, though Squirro products can also be set up on-premises or in private clouds. For on-premises or private deployments, a client _System Administrator_ is required for initial setup and the ongoing handling of software upgrades. Depending on the work being performed, the System Administrator may also be referred to as a [DevOps](../a-z/industry-glossary.md#term-DevOps) Engineer. ## Installation and Upgrade The System Administrator or DevOps Engineer will typically work with Squirro Solutions Engineers to install and upgrade the Squirro Platform. On-premises and private cloud setups are installed using Ansible. To learn more, see [Install and Manage Squirro with Ansible](../getting/install/ansible/index.md#ansible). End of support for installing Squirro on Linux manually. The [Installing Squirro on Linux](../getting/install/linux.md#install-linux) page remains available for reference only. Reference: For all other installation and upgrade information, see [Installation and Upgrade](../getting/install/index.md#install). ## Administration The System Administrator or DevOps Engineer is typically also the person responsible for configuration, authentication, operations and administrative troubleshooting. They ensure that the Squirro Platform is running smoothly and that any issues are resolved quickly, set up new users, configure permissions, and configure the system to meet the needs of the business and optimize resources.
