Abstract: This doctoral thesis deals with the development of technologies for the collection, processing and analysis of data from streams or from large data repositories following the small-service model as a building block. The main purpose of this thesis is to present and analyze the framework that can give the digital systems architect the ability to transform or structure the system that has been implemented so that it can meet the challenges of multiple data sets. The introduction of application development with mini-services has offered advantages both in terms of better rational management of services and maintenance of these systems. The increasing use of cloud computing has provided the necessary credentials to build on it a new architecture that combines service-oriented with service management flexibility. The new way of building is increasingly based on a combination of ready-to-use 'closet' services that build the new service called for. But this approach raises new questions that we are called upon to answer. They need to have systems in place to orchestrate all of these mini-services as well as introduce standards that strictly structure these services so they can communicate properly with each other. Finally, these issues of compatibility in the single channel of communication and in the way they interact must be covered by the mantle of security. An important factor as each service platform usually offers its own way of approaching the infrastructure. ix In this thesis, we introduce a methodology based on accredited security organization methodologies, enriched and modified so that it can be applied in the IT environment. The methodology must follow the flow of information in order to be able to provide better control over the data but also to meet the increased demands of the subsystems. At the same time, we analyze the model to be followed for finding micro services through marketplaces where service products will be published. Combining these services should have a strategy to meet the challenges of bringing in a lot of data. Such an analysis is presented and analyzed in detail to understand the new techniques to be followed. Finally, a blueprint is presented that is the building block for each product offered so that it can better present its services in a structured way. The development of this layout, in addition to the interoperability of the services it can provide, is necessary for the new security challenges that arise both in reference to the data and in the services themselves.
