In the past decade, many companies have moved towards the agile method of development rather than the traditional waterfall methodology. Even companies that do not strictly adhere to agile development will usually use a blend of both agile and waterfall techniques. Agile development has many characteristics that make it more suited to modern technology than the waterfall method. Today, agile development is very closely related to DevOps and the cloud.
Agile development allows companies an adaptability and flexibility that is simply not possible through traditional waterfall methodology. In a world that moves as fast as the modern tech industry, the ability to turn on a dime during the development process is invaluable to any company. The waterfall method requires a linear project schedule that advances from one stage to another while the agile method is modular and fluid. It is this same fluidity that ties agile development into enterprise DevOps and the public cloud.
