Galera Cluster beats Amazon Aurora in performance and MySQL high availability

Investigation run by Marco Tusa

CONCLUSIONS

 

MySQL/Galera was able to outperform Aurora in all tests — by execution time, number of transactions, and volumes of rows managed. Also, scaling up the Aurora instance did not have the impact I was expecting. Actually it was still not able to match the EC2 MySQL/Galera performance, with less memory and CPUs.

In light of the tests, the recommendations consider different factors to answer the question, “Which is the best tool for the job?” If HA and very low failover time are the major factors, MySQL with Galera is the right choice”.
