You build and run apps without thinking about servers. • Going forward “running software” without understanding said software won’t be a thing. • Infrastructure will be invisible, yet still elastic and optimized • Monitoring, logging analysis and observability tools will be where Operations lives and works. • Watching running software and looking for ways to make it better with be what your best technical people are doing • SRE activities will be operations job one, regardless of whether you have SREs • Reactive-->Proactive 19 © 2019, Amazon Web Services, Inc. or its Affiliates. © 2019,Amazon Web Services, Inc. or its Affiliates.
