java - EJB scalability: due to what -

Can you find the EZB scalability and which problems I have to face, for example, if I do not use EJB for large applications

Thanks in advance.

EJB does not give you any special scalability bonuses, and there is no penalty for not using them. .

Some "EJB Scalable" Hype comes from days when object pooling is considered as a performance booster.

EJB can help you write efficient code in two small ways: P>

• EJB architecture has a way of spreading business logic in two machines ( By using remote interfaces and JNDI lookup, you allow processing between the server without modifying the code)
• EJB uses the same reference for many calls to you - in some cases consistent persistence References to Jha and will help you get the most of the JPA.

  Can get without EJB.

  Anyway: You should use them, because they make code better and keep them easy to maintain and these two attributes usually help in creating a scalable app.
