Abstract & Overview
The thesis evaluates cloud architecture choices for Fineidea, a concept-stage digital innovation platform, before workloads and user volumes are known. It compares serverless, container-based, and hybrid or multi-cloud architecture options and derives preliminary design principles for Fineidea’s minimum viable product (MVP). The thesis uses a literature-based comparative approach, drawing on academic literature, official and regulatory material, standards, statistics, and selected cloud-provider guidance. It excludes deployment, benchmarking, provider selection, and primary data collection. The findings show that no architecture option is automatically sustainable, scalable, cost-efficient, or manageable. A managed serverless-led starting approach appears proportionate for Fineidea’s MVP. Container-based and hybrid or multi-cloud options become relevant when workload evidence, control, regional, resilience, or governance needs justify added complexity. Finland/EU hosting can support governance, proximity, and sustainability-relevant infrastructure reasoning, but does not guarantee compliance, performance, or sustainability.
