Enterprise integration is a messy space. It is always complex – applications, databases, new and legacy systems, complexity of requirements. People usually need to run at least dozen of applications to run things smoothly. It is never done out-of-the-box and it is always requires circles of implementations and professional services.
I caught the following picture tweeted yesterday by Stan Przybylinski of CIMdata. It provides an excellent view of integration complexity. Unfortunately, in many situations, integration is a major challenge in PLM adoption. To get full value of PLM, company should spend a fortune integrating data and processes – CAD, Bill of materials, ECO, etc.
Cloud is coming to enterprise these days. In many ways it creates a new way to think about data, software, services and maybe integrations too. The new technologies and eco-system of services can make a difference. It also creates a significant demand for openness and interoperability. This is a main reason why PLM need to learn web APIs. Web services and REST APIs are changing the way integration can be done.
Technology can make a difference. However, integrations are still hard. Few months ago, I shared my thoughts how to prevent cloud PLM integration mistakes. It comes down to three main things – 1/ lost data semantics; 2/ limitation of data transfers; 3/ transaction management in distributed and cross site environment.
Unfortunately, cloud is not a silver bullet to solve integration challenges. The demand for holistic integration continuum is still in the future. In practice, cloud applications today are replicating bad siloed behaviors of on premise applications. I captured the following picture earlier this week at Boston New Technology meetup.
This picture is the great demonstration of how bad aspects of siloed on premise applications are moving to cloud environment. Migration of applications on cloud infrastructure such as IaaS can simplify IT’s life. However, it won’t make life of users simpler. From end user standpoint, applications will still run in a silo.
What is my conclusion? The danger is to move established on premise PLM paradigms to the cloud. Technologically new cloud systems can give an advantages in terms of integrations. REST API is one example – it is much easier to code integration scenarios using REST APIs and modern web based tools. At the same time, closed data paradigms and data duplication between silos can bring well-know data spaghetti from on-premise applications to the cloud. Just my thoughts…
