MariaDB has been releasing packages for ARM for quite some time now. ARM is known to have a lower cost of ownership there-by delivering more TPS for the same cost, effectively generating cost savings. Any changes to the working production environment would surely make DBA/dev-ops anxious and we are talking about migrating to a different architecture altogether. How complex is that? Is it feasible? Is it the right time to look into it? What about the ecosystem/other aspects? We will try to answer all such questions through this talk. We would discuss the why and how aspect, highlighting the step-step approach how user could migration existing MariaDB cluster to ARM, tools compatibility, do and don't, revert back to the old system (if needed rarely), etc....
