evolve into today's rich and diverse internet. We think that SQL has become the waist of data analysis. In our time of life, data is becoming "the most valuable resource in the world" (The Economist, May 2017). Therefore, we have seen the professional database (OLAP, time series, documents, charts, etc.), data processing tools (Hadoop,spark,flink), Data Bus (KAFKA,RABBITMQ) and so on, showing the Cambrian explosion-like situation. We also have more applications that need to rely on these data i

So you have to say that people do not want to pay for commercial products, so they develop it. Also not necessarily, and do not say that the price of the purchase of commercial products and the co
multithreading. Python is still struggling in this area.
If development speed is more important than execution speed, Python has an advantage. But Swift has the "Playground" mode of the Xcode IDE.
The advantage of Python: On the one hand, Swift is a new programming language compared to Python, and Python has a bit of all the mature languages--lots of user base, lots of libraries, and mature multiplatform support. Swift is not even able to support Windows now (if not the third party libraries),
AWS, GCE, and OpenStack platforms.
5. Flynn
Flynn is an open source PAAs platform written in the go language that can be automatically built to deploy any application to the Docker container cluster running. The Flynn project, supported by Y-Combinator, is still under development and is now known as the next generation of open source PAAs platforms.

This type of monitoring tends to generate a lot of data, so it can affect performance and therefore needs to be carefully designed. For microservices monitoring tools, the storage engine can choose Graphitedb or influxdb, and the visualizer can choose Kibana or Grafana.Metrics for micro-service monitoring include:
