Generic formal patterns for cloud native application development
Generic formal patterns for cloud native application development
With advances in cloud computing and distributed systems, cloud-native applications provide immense flexibility to developers in terms of building scaleable and efficient applications and systems. One of the predominant architectures that epitomises this shift in modern application development is the service-oriented architecture (SOA). While SOA offers developers significant flexibility during system development, it inadvertently increases overall system complexity, which may result in design and implementation flaws.
To deal with complexity, formal methods offer abstraction. By conceptualising systems at higher abstraction levels, they help developers and system architects achieve a better grasp of the system's entirety and its nuances.
Moreover, in service-oriented architecture and cloud-native applications, access control is a crucial component because it serves as the gatekeeper, specifying who can access the system or use which resources or services. Therefore, it should be designed robustly to protect resources and ensure the application's security.
In this research, we mainly focus on developing formal modelling patterns to assist cloud-native application developers in securely designing their cloud-native systems. Therefore, firstly, we will develop a set of formal modelling patterns for the functionalities of serverless systems in the Event-B environment. In the next stage, we incorporate an access control mechanism for the serverless system into our previously proposed patterns. Then, to illustrate the usefulness of our patterns and approach, we model two distinct scenarios of a project management application with serverless architecture. We conclude by summarising our findings and highlighting the research's prospective directions and potential applications.

Abstract
With advances in cloud computing and distributed systems, cloud-native applications provide immense flexibility to developers in terms of building scaleable and efficient applications and systems. One of the predominant architectures that epitomises this shift in modern application development is the service-oriented architecture (SOA). While SOA offers developers significant flexibility during system development, it inadvertently increases overall system complexity, which may result in design and implementation flaws.
To deal with complexity, formal methods offer abstraction. By conceptualising systems at higher abstraction levels, they help developers and system architects achieve a better grasp of the system's entirety and its nuances.
Moreover, in service-oriented architecture and cloud-native applications, access control is a crucial component because it serves as the gatekeeper, specifying who can access the system or use which resources or services. Therefore, it should be designed robustly to protect resources and ensure the application's security.
In this research, we mainly focus on developing formal modelling patterns to assist cloud-native application developers in securely designing their cloud-native systems. Therefore, firstly, we will develop a set of formal modelling patterns for the functionalities of serverless systems in the Event-B environment. In the next stage, we incorporate an access control mechanism for the serverless system into our previously proposed patterns. Then, to illustrate the usefulness of our patterns and approach, we model two distinct scenarios of a project management application with serverless architecture. We conclude by summarising our findings and highlighting the research's prospective directions and potential applications.
