Analysis and comparison of microservices and serverless functions on AWSBucevski, Metodija (Avtor) Jurič, Branko Matjaž (Mentor) AWS LambdaPerformance testingMicroProfile StandardsThis thesis makes a comparative analysis between microservice and serverless architectures, with practical implementation in AWS for an e-commerce website. The study is divided into 3 segments: theoretical background, which includes: cloud computing, web architectural patterns, and microprofile standards. The second segment includes the design and implementation of both architectures together with practical guidance for implementing MicroProfile standards in a serverless environment. In the third segment, load tests are performed to measure session related metrics and memory utilization under different user arrival traffic patterns, followed by a section on cost comparison and the experience of building and development. The results showed, that serverless outperforms microservice architecture in terms of speed of the development and deployment process. Microservice architecture showed less resource utilization and higher controllability. Regarding cost-efficiency, performance and scalability, there is no clear winner since they depend on user arrival pattern.20242024-10-02 14:45:00Magistrsko delo/naloga163139VisID: 37114COBISS_ID: 210450179sl
