As reported before, we investigate quality characteristics of decentralised applications in analogy to the usual assessment of microservice artefacts. We are happy to report on how we shared the intermediate results at the most recent Azure Blockchain meetup in Zurich, apart from reporting on the event itself.
Looking into a possible post-cloud world, we see mentions of different computing paradigms, many of them based on decentralised structures to overcome scalability and user control limitations. Among them is blockchain-as-a-service (BCaaS or BaaS), mimicking the platform-as-a-service (PaaS) user experience for both application providers and consumers. In PaaS, providers first sign up and subscribe to the platform, then design and build their applications and deploy them to the platform where it is executing either permanently or upon incoming network requests or other event triggers. Additionally, developers may advertise their apps at technology-specific hubs such as AWS SAR or Helm Hub. Consumers then adhere to the application terms, which might require a sign-up at the provider site, before being able to invoke and make use of the application.
