For deploying environments and configuring servers, the following are used:

Configuration Management Systems
- Ansible
- Chef
- Puppet
- SaltStack
Container Orchestration Tools
- Kubernetes
- Docker Swarm
- Apache Mesos
Infrastructure as Code (IaC) Tools
- Terraform
- CloudFormation (AWS specific)
- Azure Resource Manager (Azure specific)
- Google Cloud Deployment Manager (GCP specific)
Deployment Automation Tools
- Jenkins

The choice of a specific tool depends on the project specifics (cloud platform, technologies used, team size). Often, a combination of several tools is used. For example, Terraform for infrastructure creation and Ansible for server configuration.

An example of using Ansible to configure a web server:

# playbook.yml
---
- name: Configure web server
  hosts: webservers # Server group from inventory
  become: yes # Run tasks as root
  tasks:
    - name: Update apt cache
      ansible.builtin.apt:
        update_cache: yes # Update package cache

    - name: Install nginx
      ansible.builtin.apt:
        name: nginx
        state: present # Install nginx

    - name: Start nginx service
      ansible.builtin.systemd:
        name: nginx
        state: started # Start nginx service
        enabled: yes # Enable autostart on boot
