In distributed systems, failure is normal. Hardware failures that are rare, when multiplied by thousands of machines, become common. Therefore failures are assumed, designs work around them, and software anticipates them. Failure is an expected part of the landscape.

To manage a large distributed system, one must have visibility into the system. The ability to examine internal state—called introspection—is required to operate, debug, tune, and repair large systems.

A typical response to a risky process is to do it as rarely as possible. Thus there is a temptation to do as few releases as possible. The result is “mega-releases” launched only a few times a year. However, by batching up so many changes at once, we actually create more risk. How can we be sure thousands of changes, released simultaneously, will all work on the first try? We can’t. Therefore we become even more recalcitrant toward and fearful of making changes. Soon change becomes nearly impossible and innovation comes to a halt.

Poverty on the rise… in the burbs

Cities, for the first time in 100 years, are growing faster than the suburbs. Meanwhile, poverty has grown everywhere rapidly, even in places not thought possible:

While the overall suburban population grew slightly during the previous decade, the number of people living below the poverty line in the suburbs grew by 66 percent, compared with 47 percent in cities. The trend quickened when the Great Recession hit, as home foreclosures and unemployment surged. In 2010, 18.9 million suburban Americans were living below the poverty line, up from 11.3 million in 2000
