Scalability (with Terracotta)

Last night, I attended a meeting about Terracotta and the presenter was the creator, Ari Zilka. Among his slides was what i found an interesting slide about Terracotta’s advantages : scalability and availability.

I reproduced it here. Scalability is a term often used in the computing area.

Writing data in memory is less scalable than writing on hard disks but on the other side data written in memory is more available (in terms of speed access) than data written on disks.
