The first one is Architectural Drift, which is - -4 -00:00:08,109 --> 00:00:12,140 -the introduction of architectural design decisions that are orthogonal to - -5 -00:00:12,140 --> 00:00:15,870 -a system's prescriptive architecture. That is, they're not included - -6 -00:00:15,870 --> 00:00:20,080 -in, encompassed by, or implied by the prescriptive architecture. - -7 -00:00:20,080 --> 00:00:22,300 -And the result of Architectural Drift is that you - -8 -00:00:22,300 --> 00:00:25,220 -start from a clean architecture, like the one that I'm - -9 -00:00:25,220 --> 00:00:28,830 -showing here, and then you start adding pieces without following a clear plan. - -10 -00:00:28,830 --> 00:00:32,229 -Like, for example, here, we add an additional room here, but we don't really - -11 -00:00:32,229 --> 00:00:34,380 -do it in the right way so we need to add something else - -12 -00:00:34,380 --> 00:00:37,090 -to keep it stable. And then maybe we want some more room so we - -13 -00:00:37,090 --> 00:00:40,310 -add a tent. And then another side of the house, it doesn't really - -14 -00:00:40,310 --> 00:00:43,540 -follow the same architecture but it doesn't matter, we just put it there because - -15 -00:00:43,540 --> 00:00:46,690 -we want to expand. And maybe then we want to put something classic - -16 -00:00:46,690 --> 00:00:48,210 -there, even though it doesn't really fit - -17 -00:00:48,210 --> 00:00:50,520 -the overall design and the overall architecture. - -18 -00:00:50,520 --> 00:00:52,160 -So I think you get my point, the fact - -19 -00:00:52,160 --> 00:00:56,210 -that the architecture then becomes unnecessarily complex, hard to understand - -20 -00:00:56,210 --> 00:00:58,410 -and ultimately awkward, just like the one that I'm - -21 -00:00:58,410 --> 00:01:00,880 -showing here, that goes from the original building into this - -22 -00:01:00,880 --> 00:01:04,870 -final monstrosity. The second concept is Architectural Erosion, which - -23 -00:01:04,870 --> 00:01:08,560 -is the introduction of architectural design decisions that violate a - -24 -00:01:08,560 --> 00:01:12,070 -system prescriptive architecture. So in this case, that we were - -25 -00:01:12,070 --> 00:01:14,070 -introducing decisions that were orthogonal, - -26 -00:01:14,070 --> 00:01:15,580 -here, were introducing this decisions - -27 -00:01:15,580 --> 00:01:17,410 -that don't comply with the prescriptive - -28 -00:01:17,410 --> 00:01:20,140 -architecture. And the result of Architectural Erosion - -29 -00:01:20,140 --> 00:01:22,590 -is typically a poor architecture an - -30 -00:01:22,590 --> 00:01:24,550 -architecture that is going to have problems in - -31 -00:01:24,550 --> 00:01:27,040 -the future. So both Architectural Drift - -32 -00:01:27,040 --> 00:01:29,640 -and Architectural Erosion take you away in - -33 -00:01:29,640 --> 00:01:32,940 -different ways from what you think your software architecture is or should be. |
