   === Tiering
   
  +Ehcache 3, as in previous versions, offers a tiering model to allow storing increasing amounts of data on slower tiers.

positive.code: ----
  
  <1> If you wish to use a cache in read-through/write-through caching pattern, you'll have to implement
      `CacheLoaderWriter` and register it.
  
  ==== Write-Behind Cache
  
  
negative.code: Sharing services can have disastrous effects in your application if the user is not careful enough.
  Configuring services using instances opens the door for sharing the same service instance across caches but that feature
  should be used with extra care.
  Configuring services using class references is the recommended way as Ehcache will then create and inject the required instances itself.
  
  NOTE: By now you are familiar with configuring different services using actual instances or using class types of
  loader-writers, serializers etc. It is desirable to have some cleanup performed on these instances once you are done
