8. Instance Partitioning

9. Database Partitioning

11. Table Partitioning: Common Scenario “Sliding Window” New data is added continually (every minute, hourly, Daily, Weekly, Monthly) Data must be scrubbed, indexed, etc. As data ages, data is modified less frequently and then - not at all. Eventually, it may be discarded Sliding Window Time Obsolete Hot Read-Mostly Read-Only

14. HA and scalability N+1 Clustering Smart management enables fast scalability by adding servers, databases, instances, partitions etc.

15. Cost reduction Page Level Data compression – saves up to 50% of disk storage (and reduces IO) Smaller partitions may reduce indexes size by 30% (!) – critical in huge environments Moving historical to cheaper storage/media No need for Mega servers - Standard servers are doing the job
