To compete with agility and speed, companies can no longer afford complex, lengthy and expensive coding of applications, or massive, multi-year system implementations. What’s needed is a new way to build software — faster, flexible and more liquid — with reusable components that allow for rapid assembly of applications in support of dynamic business needs. This approach requires modular architectures, next-generation integration techniques and a cloud-first, mobilefirst mindset. Application programming interface (API) architectures underpin liquid applications, opening them up to flexibly and efficiently access internal or external software components and services. Engineering innovations such as Agile and DevOps further accelerate development and deployment.
