-functional organizational structure is already standard in the previous article, "adopting" a microservices architecture enterprise, such as Amazon, and you no longer have to justify the implementation of this thing. The rest of the key is how to get people from different backgrounds to work together. It is also possible to see the next hot spot in the DDD field, and a modular collaboration workshop like e

Micro-service Combat (III): Inter-process communication in the micro-service Architecture "Editor's note" This is the third article that uses a microservices architecture to create its own application series.

between SOA and microservicesIn fact, the service architecture has been able to solve the needs of most enterprises, then why should we study micro-services? First talk about their differences;MicroServices architecture emphasizes that business systems need to be completely modular and serviced, and that a component is a product that can provide services independentlyMicroServices no longer emphasize the relatively heavy ESB enterprise service bus in
uses 8G of memory, and after splitting into a micro-service, it only needs 5G to 6G of memory, saving at least 2G of memory.But it's not going to be that simple. One of them is responsible for providing rest APIs externally and is the most critical part of the entire system. To increase availability, they deployed 4 instances in Europe, North America, and Asia respectively. In this way, the microservices u
stack is not unified, each API abstraction and encapsulation, error-prone. The lack of documentation and the use of booting requires a lot of support work. Behind closed doors, the output of micro-services often can not meet demand, running for a period of time will be gradually discarded. After years of exploration and practice, Sparkpost has summed up a number of best practices to guide them in building a persistent and stable microservices AP

Today, someone asked me a question: "Why would someone choose SOAP (Simple Object access, Protocol, and rather than REST (representational state Transfer, representational status pass) It? "My answer is:" I often hear the general empirical law is 'use REST unless you have a clear reason to use SOAP .’”。 He asked again, "for example?" "I thought for a minute, and then honestly answered that I had not yet met

I have an inference that, in the computer world, all the important concepts that the developer remembers, there is a cool name acronym, or the developer will soon leave it behind. Ajax, SOAP, and rest, for example, attest to this. Rest can be widely used in the computer field, and its path is unusual. This term was created by Roy Fielding.
