Silos are a type of IT work structure in which teams are split and have distinct aims and cultures. This type of work structure hampered the efficiency of the SDLC (Software Development Life Cycle), as they were overshooting the budget due to recurring errors, crossing time-limits, and eventually generating a lot of waste (in terms of rework, defects, and so on). DevOps was created to combat and eliminate this ineffective Silos work structure.
