Nati Shalom's Blog: Latency is Everywhere and it Costs You Sales - How to Crush it - My Take

As usual, a very interesting blog from the CTO of GigaSpaces.

With the graph above we see that the IMDG [In-Memory Data Grid, which runs on top of MySQL] scales very close theoretical linear scalability. The above results were achieved with an IMDG running on 2 partitions. Better scalability can be achieved by increasing the number of partitions.

Read more about how to scale-out the data-tier in Scaling-out MySQL.

To enable this level of on-demand scalability we used our new Cloud Framework, which combines the GigaSpaces SLA-driven container as the application deployment virtualization layer, Amazon EC2 as the machine level virtualization layer, and the GigaSpaces application server as the middleware virtualization layer. This way we can provision new machines as soon as the SLA on the web-tier is breached (measuring latency, in this specific case).
