"Very big tutorial" sounds like "book" to me. A search on Amazon or some publisher's sites might help find one that covers these topics with a Java slant.

Active-Active is more expensive but provides continued operation when one side goes down. Active-Passive does not provide continuous operation, and make take several minutes to spin-up the inactive side.
Designing systems with loose coupling is a big advantage when it comes to addressing sustained business operations in the face of outages. Hence the popularity of Service Oriented Architecture and Enterprise Service Bus patterns.
Moving data into distributed cache or in-memory database instances is a good step forward also.
Single-sign-on and mutual authentication promote seamless hand offs between instances and preservation of state between transactions.

Book is also fine to me but I am not able to find one. Could you please point out some books?
Thanks.

It was like a bouncer to me. Never heard about these strategies. Please give pointer for detailed study.
Thanks.

MySQL book has some topics, it will surely help. But they are more related to configuration that is also with database. I am looking preferably conceptual thing only (not specific to any technology) and if it is related to any implementation then preferably with Java web servers.
Thanks for spending your valuable time on me.
