![]() It’s a collaborative human endeavor, and our tooling-and the automation it supports-is how we get this work done. Sometimes we hear teams say, “We use or automate, so now we’re doing DevOps!” But as noted above, tooling and automation are part of how you implement DevOps (the means), not DevOps itself. Myth: Having DevOps tools equals doing DevOps Once we understand what DevOps is, it’s easier to identify what it isn’t-let’s look at a few misconceptions you may have heard before. ![]() The result of DevOps is a better product, delivered faster and more reliably.The means of implementing DevOps is process and tooling.Altogether, it’s a combination of focus, means, and expected results. But most importantly, DevOps is about enabling people to collaborate across roles to deliver value to end users quickly, safely, and reliably. ![]() For developers, DevOps focuses on both automation and culture-it’s about how the work is done. None of these are wrong, and they are all important aspects of DevOps-but they don’t quite fully capture what’s at the heart of DevOps: the essential human element between Dev and Ops teams, when collaboration bridges the gap that allows teams to ship better software, faster.įor organizations, DevOps provides value by increasing software quality and stability, and shortening lead times to production. What is DevOps?ĭevOps has been defined in many ways: a set of practices that automate and integrate processes so teams can build, test, and release software faster and more reliably a combination of culture and tools that enable organizations to ship software at a higher velocity a culture, a movement, or a philosophy. Here’s what we’ve learned-and some common DevOps misconceptions we’ve encountered along the way. What we call “DevOps” will often differ between organizations, yet one thing remains the same: DevOps is defined by people building software and how they work together, not simply by what’s in their toolchain.Īs part of GitHub’s Professional Services team, I’ve had the opportunity to see the way many companies have adopted DevOps and what it looks like for teams in their day-to-day work. So while this concept might not be front of mind when you walk onto set, it’s a good piece of knowledge to keep in your back pocket.By now, most people in technology are familiar with the term DevOps. Most consumer cameras have built in filters, or filters that are placed on the outside of the lens, so these calculations usually only come into play for higher-end or older cameras.ĭepth of focus is a term that is often forgotten until it becomes a problem cinematographers might drive themselves crazy cleaning filters and adjusting depth of field settings, not realizing that their image sensor is outside the range of focus. Gels and filters are often placed between the lens and a camera’s image sensor, and so adding or subtracting them changes the distance between the plate and the lens. But for people who are serious about photography or cinematography and are dealing with high-end cameras, it’s a key concept to know.Ī camera operator will most often use the depth of focus formula when they are inserting or removing gels or UV filters from their camera. Why This Matters Why is depth of focus important?įor those aforementioned reasons, depth of focus is the more obscure cousin of depth of field, and most casual photographers and cinematographers can get by without ever understanding what it is. ![]() This isn’t often a desired effect, and if it is, you can usually have your frame be entirely out of focus by adjusting your lens’ focus ring or depth of field rather than moving your image sensor. If your image sensor is outside the acceptable range of focus, your whole image will be blurry, not just certain objects within it. Depth of focus, meanwhile, is rarely altered in service of a creative choice. ![]()
