| Abstract |
Web services offer reusable, well-designed and pretested component solutions for their consumers. Whilst striving for stability and reliability, web services experience numerous evolutive phases due to changes in application domain or changed requirements, and often cause breaking compatibility. This thesis proposes automated generation of migration guides, that encapsulate a generic description on how to migrate breaking changes. Our approach focuses on generating migration guides for web services built on Apodini, a novel internal Domain Specific Language that describes web services declaratively. The applicability of our research is demonstrated on industry projects from telecommunication branch and healthcare industry in cooperation with Mobile Software AG. |

| Abstract |
We propose the development of a toolkit for automated and user-configurable distributed deployment of a Swift program implementing a web service. The web service is defined as a composition of individual services, via the Apodini internal domain-specific language (DSL) [Sch20]. Our toolkit analyses the web service’s structure as expressed via the DSL, taking into account additional nonfunctional requirements. From this information it determines the deployment strategy which best satisfies these constraints. The resulting distributed system can be deployed to arbitrary target platforms, ranging from conventional web servers to FaaS providers such as AWS Lambda. |

| Abstract | When choosing a protocol, server-side developers have many options available, ranging from building a JSON based API, to a RESTful Service, to a GraphQL API or using gRPC. The chosen protoccol will, in practice, shape the structure of a server’s implementation. Schmiedmayer proposes Apodini [Sch20], an internal domain-specific language that focuses on describing a server’s implementation declaratively and independently from the protocol. In this guided research we want to explore the feasibility and nuances of the Apodini internal domain-specific for different programming languages such as Swift and Kotlin. |

A Process Model for Client Migration after Service Changes in Distributed Systems

|
| Abstract | Modern web-based APIs offer a broad variety of services for numerous distributed client applications. As with any other software product, Web APIs must evolve to remain functional and successful. Ideally, an API contract creates a consistent, shared understanding of its service between provider and consumer. The provider-side evolution of an API often introduces changes to this contract that consumers need to manually adapt to. Thus far, there is no automated process for migrating between different Web API versions. In this thesis, we propose a tool-supported workflow using a novel machine-readable migration guide. We evaluate our findings by implementing an automated migration tool for OpenAPI specifications. You can find the open source implementation at https://github.com/Apodini/Pallidor. |

|
| Abstract | This thesis aims to focus on incorporating event based actions into a mainly static Domain Specific Language (DSL). When looking at a concrete DSL that facilitates the implementa- tion of RESTful APIs event based behaviour could include two-way communication and the ability to notify clients about changes from the server. The goal is to extend the work on Corvus, a declarative framework for server side Swift. By adding the functionality for WebSockets and push notifications event based aspects can be implemented to facilitate RESTful APIs.

Semi-Automated System Decomposition Using Static and Dynamic Code Analysis

|
| Abstract | We want to propose an approach for semi-automated management of system decomposition utilizing static and dynamic code analysis. Semi-automated management of system decomposition describes the process of decomposing a software system into a fine grained service oriented architecture through a suite of tools that are managed by a software architect. Our decomposition management software supports this transition by continously analyzing the current state of the decomposition process with an extendable tool suite. With the help of user input, the business capabilities of the system under study are determined and associated with source code to create firm module boundaries. For this our software utilises static and dynamic code analysis. In this thesis we focus on the decomposition of monolithic software systems based on server-side swift, but the approach can be used for other languages and system architectures as well.

March 15, 2020 - July 15, 2020
|
| Abstract | This thesis is exploring the creation of a domain-specific language (DSLs) for describing interfaces of web services. We investigate the possibility of a Swift language based definition language that allows Swift developers defining their web service interfaces by using Swift syntax and concepts independent of the concrete communication protocol. Therefore we compare different communication approaches and investigate their similarities and differences. As additional goal we want to explore possibilities that allow developers the usage of ORM functionalities (e.g. database connection and access, model definition, relations) of traditional Swift powered frameworks. You can find the open source implementation at https://github.com/Apodini/APIKit. |

| Abstract | WebAssembly is a new abstract instruction set primarily designed to target web browsers from higher level programming languages. To enable full stack web development in Swift, the Swift compiler should support targeting WebAssembly. This thesis will try to extend the Swift compiler to support WebAssembly and to compile the Swift Standard Library. Furthermore, the interaction with a web browser’s JavaScript API and the Document Object Model should be possible from Swift. Finally, the results will be evaluated by building a web application in Swift, including the client side code that runs in the browser.

| Abstract | This thesis attempts to address the issue of synchronizing the networking stack of client-server codebases by providing a full solution to write a client-server architecture using GraphQL in Swift. We want to provide a clean and readable declarative API for creating a GraphQL Server and a similar API for the client, as well as tools to ensure that these codebases continue being in sync. We plan to achieve the synchronization by autogenerating client code from the GraphQL schema, and updating the client automatically when the server changes.

| Abstract | This thesis details the development of a web-based user interface framework for the Swift programming language. The proposed framework can be used to deploy a Swift application to a server that serves a lean JavaScript application. The proposed framework should let a developer define a user interface using the SwiftUI syntax. The server should use a WebSocket based connection to update the server on user input and update the website based on server-side changes.

| Abstract | Ever-increasing complexity in micro-service architectures requires scaling and deployment of services according to current usage information and resource availability. In order to ensure the availability of a distributed server application, it is crucial to provide a maintainer of a micro-service application wide-reaching monitoring capabilities custom fit to its specific use case. We propose to develop a framework to provide tracing information about a server application and visualizing it on a client device using dynamic UI generation. |

| Abstract | The goal of this thesis is to develop a tool that simplifies the client-side developing workflow when using a gRPC based networking stack. We propose encapsulating networking logic in a separate Swift package and extending it for the use with commonly used frameworks such as Combine. We plan to build this abstraction layer above the SwiftNIO based grpc-swift framework. We plan to combine this abstraction layer with a CI-based code generation workflow to simplify the development process when syncing client and server codebases.

| Abstract | The thesis investigates the improvement of current deployment strategies. We propose a mechanism that learns the behavior of the system within a Kubernetes Cluster by monitoring the system as well as user requests. We propose an intelligent deployment mechanism that can predict the best possible deployment strategy to optimize resource usage. We plan to visualize the relationships within the services of the cluster and the predictions made by the tool.
