How does the concept of archival provenance relate to the field of archival science?4 answersThe concept of archival provenance is fundamental to the field of archival science. Provenance refers to the origin and history of records, and it plays a crucial role in organizing and describing archival knowledge. It helps establish the context in which records were created, used, and maintained, allowing for a better understanding of their authenticity and reliability. Provenance is not limited to identifying a single creator of records but also encompasses the relationships between records and their broader context. It has been applied in various domains, including government information management and digital environments, where it ensures the preservation and usability of electronic records. The principle of provenance has evolved over time, and its implementation through metadata, such as provenance metadata, has further enhanced its core value.
Article for new proposed migration software to microservice?4 answersA novel approach to migrate legacy monolithic applications into microservices is proposed in this paper. It includes code decomposition, communication establishment between microservices, and data management. Another paper proposes a new effort estimation model called Service Points to estimate the effort required for migrating SOA applications to microservices. The model is compatible with the design principles of microservices and provides a systematic and formal way of estimating the effort. Additionally, there is preliminary work on a data-centric process to identify microservices by decomposing the database into clusters and performing database schema analysis and clustering.
Are most microservice architecture implemented with docker?5 answersMicroservices architecture is a popular approach for developing cloud applications. While there is a lack of concrete information on the technical options available for microservice software architects, Docker is widely used for implementing microservices. Docker provides a containerization technique that allows each microservice to be isolated and deployed independently, making it a suitable choice for implementing microservices architecture. The use of Docker in microservices architecture offers benefits such as scalability, flexibility, and improved productivity. However, it is important to note that further comparative assessment with industrial systems is needed to better understand the recurring principles and patterns around microservices.
How microservice relate to cloud?4 answersMicroservices are a popular architecture for building cloud-native applications. They enable individual users to access local data and improve community wellbeing. Microservice applications consist of many interacting microservices that can leverage different cloud servers to distribute computational load horizontally. Cloud computing provides flexibility for service providers to add or remove resources based on workload, ensuring quality of service (QoS) requirements are met. Microservices can be deployed and scaled independently, simplifying software development and operation. They can also be instantiated in cloud and edge data centers to improve performance metrics such as user delay. Additionally, microservices can utilize IoT sensors and cloud systems to aggregate and visualize data, such as driver emotions on a travel map, to prevent accidents. Overall, microservices and cloud computing are closely related, enabling flexible and efficient application development and deployment.
What are the benefits and challenges of using microservices in cloud computing environments?5 answersMicroservices in cloud computing environments offer several benefits and challenges. One significant advantage is the ability to duplicate microservices to enhance overall service quality and meet service-level contracts. However, the complex interactions within microservice meshes introduce challenges in managing shared hardware resources and identifying critical resource bottlenecks. Another benefit is the flexibility of cloud computing, allowing service providers to scale resources based on workload demands. This enables them to minimize resource cost and latency while maintaining the Quality of Service (QoS) requirements. Additionally, microservices provide a small and independent architecture that interacts and responds to messages via lightweight technologies, ensuring data privacy in shared computing and networking environments. Overall, microservices offer agility and scalability, but also require efficient resource management and addressing complex interactions for optimal performance in cloud computing environments.
How to generate alerts from provenance graphs?5 answersGenerating alerts from provenance graphs can be achieved through various techniques. One approach is to use linguistic explanations to transform provenance graphs into textual explanations, allowing users to directly understand the information. Another method involves parsing audit records into provenance graphs and using grammatical inference to create a behavioral model of multiple nodes at once. This model can then be used to identify anomalous events in the cluster, enabling the generation of alerts. Additionally, access control languages can be used to regulate access to provenance data, ensuring that only authorized users can query and view the graphs. By combining these techniques, it is possible to generate alerts from provenance graphs, providing valuable insights into system intrusions, data lineage, and complex activities such as Advanced Persistent Threats (APTs).
