2. Load balancing and auto-scaling tests (Figure 12.3). These two
tests can be used to test the improvements of the performance when
using load balancing or auto-scaling for CLH. Testers can test
stepwise to use 10 to 400 numbers of concurrent requests to do the
tests. In addition,testerscan also set up how many instances will be
brought up in the test, for example, 1, 2, and 5 instances.
Figure12.3 shows the workow of the load balancing/auto-scaling
test. Steps 1, 3, 4, 5, 6 can be referred to as the matrix test. Step 2
sets up the load balancing or auto-scaling as det ...
