Performance Engineering: New and Conflicting Trends

Performance engineering is adjusting to major industry trends - such as cloud computing, agile development, and DevOps. As systems scale and sophistication skyrocket, performance definitely gets more attention. However, such adjusting happens in different, sometimes conflicting, ways and the future of performance as a separate discipline is not clear. We may observe integration with development (''Shift Left'') and operations (''Shift Right''), as well as appearance of new disciplines that includes parts of performance engineering (such as SRE and FinOps). While some trends are clear (such as continuous performance testing or observability) - others are still being formed. It is not trivial to define the performance engineering body of knowledge at the moment.
