“…We picked this case study because it is a large-scale comprehensive case covering all Stages of the roadmap design process. This case was also presented in our paper introducing the CAPABILITY-BASED SERVICE pattern (Frey et al, 2014). We identified similar situations at other companies, but not all cases were so comprehensive or only limited information was available.…”

“…There are different approaches and patterns for service identification. For example, Frey et al propose applying the CAPABILITY-BASED SERVICE pattern (Frey et al, 2014) if the services must be identified within a short timeframe and if there a comprehensive business process model is missing. The CAPABILITY-BASED SERVICE pattern is a top-down approach which is based on business capabilities.…”

“…Key drivers and expected benefits are illustrated in Figure 4. (Frey et al, 2014) Business executives as well as IT executives prioritized which legacy systems must be replaced and shutdown as a result of the modernization program. The executive clearly stated that reducing costs is the primary goal.…”

“…In addition to technical aspects of SOAs a lot of research studies and patterns have been published concerning service identification and business-IT-alignment 1 . For example, the CAPABILITY-BASED SERVICE pattern (Frey et al, 2014) helps identifying SOA services based on a model of business capabilities. Other methods and patterns consider business processes as driving factors.…”

Many organizations still operate their business based on old legacy systems which cause high maintenance costs and are difficult to change. After the hype about service-oriented architectures (SOAs) was gone, they were implemented successfully and helped replacing old legacy systems with flexible services, for example at large companies in the finance or logistics industry. While recent research and the pattern literature cover the technical aspects of SOA and the alignment between business and IT, defining and planning a roadmap for a SOA modernization program, which is essential for initiating such a program and getting the necessary commitment, has not been in the focus of research yet. Thus, we propose a design process for the definition of a high-level roadmap. It considers determining architectural decisions and planning decisions by selecting appropriate patterns and reference architectures. Furthermore we define a heuristic for the roadmap planning activities, because we see a lack of appropriate planning patterns. A case study explains how the roadmap design process has been applied in a large-scale industry project concerning a SOA modernization program of a global logistics provider. The pattern-based process should motivate pursuing further research about roadmap design processes and patterns and provide guidance for industry experts.

As more organizations are placing cloud computing at the heart of their digital transformation strategy, it is important that they adopt appropriate architectures and development methodologies to leverage the full benefits of the cloud. A mere "lift and move" approach, where traditional monolith applications are moved to the cloud will not support the demands of digital services. While, monolithic applications may be easier to develop and control, they are inflexible to change and lack the scalability needed for cloud environments. Microservices architecture, which adopts some of the concepts and principles from serviceoriented architecture, provides a number of benefits when developing an enterprise application as compared to a monolithic architecture. Microservices architecture offers agility and faster development and deployment cycles, scalability of selected functionality, and the ability to develop solutions using a mixture of technologies. Microservices architecture aims to decompose a monolithic application into a set of independent services which communicate with each other through open APIs or highly scalable messaging. In short, microservices architecture is more suited for building agile and scalable cloud-based solutions. This chapter provides a practicebased view and comparison between the monolithic and microservices styles of application architecture in the context of cloud computing, and proposes a methodology for transitioning from monoliths to cloud-based microservices.
