Microservices is a notion that claims to enable the creation of large, complicated systems that must operate in an unpredictable environment. Microservices should therefore promote resiliency. This paper provides possible solutions on fault tolerant of microservices and solve the problem of frequent shutdown or restart of services through advance research on hybrid design patterns based on Agile – Iterative and Incremental approach through a process called dynamic fusion. Fusion of objects Microservices during runtime will ensure that there is no need for system restart. Though currently there are many techniques to achieve binding, still it is widely found that the microservice needs to be restarted whenever there is a new increment or iteration. This area of research is to find out all possible and feasible options of dynamic binding via a deep study on object-oriented analysis and design techniques which comes out with various possible technical solutions. This study is based on "SOLID" software design concepts in general and how they are applied to microservices difficulties specifically to dynamic fusion of atomic microservices in a complex microservices architecture on cloud. This research work would pave a way for the future programmers to understand how to achieve dynamic binding in the real dynamic fashion as per the principles of agile approach.
