SRE ensures that our servicesâ€ both our internally critical and our externally-visible systemsâ€ have reliability and uptime appropriate to users' needs and a fast rate of improvement while keeping an ever-
watchful eye on capacity and performance.
SRE is also a mindset and a set of engineering approaches to running better production systemsâ€ we build our own creative engineering solutions to operations problems.
Much of our software development focuses on optimizing existing systems, building infrastructure and eliminating work through automation.
As SREs are responsible for the big picture of how our systems relate to each other, we use a breadth of tools and approaches to solve a broad spectrum of problems.
Practices such as limiting time spent on operational work, blameless postmortems and proactive identification of potential outages factor into iterative improvement that is key to both product quality and interesting and dynamic day-to-day work.
