It provides very fast backend cache with full cache support that doesn’t require low-level file system cache and stable performance for high traffic Magento stores.

Advantages of Redis:

• Provides extreme in-memory storage
• Vertical & Horizontal Scaleable
• Can be Shareable among Multiple Servers
• Supports cache tag

Also, the requirements of Redis is very simple like.

• Redis Server

Setting Up Redis as Cache Storage in Magento 2

Default Magento 2 Supports all Redis pre-requirement out of box so you don’t need to worry more, all you need to do is just add following code to your Magento Root/app/etc/env.php

'cache' =>
 array (
 'frontend' =>
 array (
  'default' =>
    array (
      'backend' => 'Cm_Cache_Backend_Redis',
          'backend_options' =>
        array (
          'server' => '127.0.0.1', or ‘localhost’,
          'port' => '6379',
             'persistent' => 0,
             'database' => '0',
             'force_standalone' => '0',
             'connect_retries' => '10',
             'read_timeout' => '30',
             'automatic_cleaning_factor' => '0',
          'compress_data' => '1',
             'compress_tags' => '1',
             'compress_threshold' => '20480',
             'compression_lib' => 'gzip',
      ),
  ),
  ),
),

Setting Up Redis as Session Storage in Magento 2

'session' =>
  array (
 'save' => 'redis',
 'redis' =>
    array (
     'host' => '127.0.0.1', or ‘localhost’,
     'port' => '6379',
     'password' => '',
     'timeout' => '5',
        'persistent_identifier' => '',
     'database' => '1',
        'compression_threshold' => '2048',
     'compression_library' => 'gzip',
     'log_level' => '1',
        'max_concurrency' => '6',
        'break_after_frontend' => '5',
        'break_after_adminhtml' => '30',
        'first_lifetime' => '600',
        'bot_first_lifetime' => '60',
     'bot_lifetime' => '7200',
        'disable_locking' => '0',
        'min_lifetime' => '60',
        'max_lifetime' => '2592000'
 )
)
