  • 6. Elements of Scalability ● Vertical Scalability – single component responding to load ● Largely driven by efficient resource usage ● Horizontal Scalability – more components responding to load ● Architecture that allows “divide and conquer” 6Copyright © 2012, Oracle and/or its affiliates.

  • 14. Design for Growth from the Start ● Separation of concerns from the start ● Business Logic ● Natural place for units of work, partitioning ● Natural point to build APIs to deliver services ● Persistence Logic ● Easier to tune/fix persistence performance issues – once - ● Easy to cache if in one place 14Copyright © 2012, Oracle and/or its affiliates.

  • 15. This Lab ● MySQL in a replication hierarchy ● Managed by MySQL Sandbox ● “Sakila” Schema ● Simple harness over a layered service architecture ● Spring, Hibernate, EhCache ● Evolution ● Performance, Partitioning by workload, (further into cells) 15Copyright © 2012, Oracle and/or its affiliates.

  • 16. Take Aways ● Design for scale up front ● Demarcate units of work with transactions ● Makes it possible to load balance ● Natural cleave point for partitioning by service ● Compartmentalize persistence ● Fix performance issues once ● Add caching in one place ● Testability 16Copyright © 2012, Oracle and/or its affiliates.
