It contains a literary review of other articles in the field. The thesis also describes a test performed\nwith the Go programming language.\nBased on the literary review, gRPC and Protocol Buffers may double the speed of data transfer and bring down the size of the data that\u2019s transmitted. On the other hand, it is possible to\nspeed up the JSON and REST technique by using a JSON library best suited for the use case\nand by using Gzip compression in the REST API. Sometimes it can also be preferable to use\na dedicated messaging protocol tailored for the system. This, however, makes co-operation\nwith other systems difficult. Using a message queue may also be a good alternative, especially if there\u2019s a need to balance the load, but adds some complexity.\nIn the original research gRPC and Protocol Buffers turned out to be a good choice for a microservices based system used for reading IoT messages with the OPC UA protocol and then\ntransmitting them over a network to another microservice. For a case where both microservices were run on the same computer, JSON and REST turned out to be a slightly faster alternative.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-11-24T11:03:05Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-11-24T11:03:05Z (GMT).
