title: Spring Boot, caching with EhCache
body: <p>I need to cache some data in my application and I am thinking about use Ehcache. And I have several questions:</p>
  
  <ol>
  <li>Do I need another server for Ehcache?</li>
  <li>Do I need some another client to work with Ehcache?</li>
  <li>How Ehcache works with multiple instances? Is it even possible to create something like shared cache using Ehcache?</li>
  </ol>
