Today, I will talk to you about the difference between SOA and micro-service architecture, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

First of all, it is certain that SOA and micro services are indeed in the same line. The concept put forward by the great god Martin Fowler can be said to sublimate the concept of SOA and take it a step further. Its core idea is in the field of application development, the use of a series of micro services to achieve a single application, or the purpose of micro services is to effectively split applications, achieve agile development and deployment, can be written in different programming languages. On the other hand, SOA may have a broader meaning and less accurate meaning.

Secondly, in terms of implementation, both of them are neutral, language-independent and cross-platform. Compared with SOA, micro-service framework will bring greater agility and provide lighter and more efficient development for you to build applications. SOA is more suitable for business process choreography and application integration in large enterprises. In addition, there are micro-services that are even de-ESB, decentralized and distributed, while SOA is still based on ESB and is implemented by a large number of WS standards.

Thirdly, in terms of service granularity, since it is micro, it is inevitable that micro-services advocate fine-grained services, reuse composition, and even each operation (or method) is independently developed services, small enough to no longer split. While SOA does not have such extreme requirements, it only needs the standardization of the interface contract, the internal implementation can be more coarse-grained, and micro-services are more likely to decompose applications for scalability, load balancing and improving throughput, but it also leads to problems of breaking the data model and maintaining consistency.

Finally, in terms of deployment mode, this is the biggest difference. Compared with Monolithic's Java EE deployment architecture, WARs is packaged through the presentation layer, and the business layer is divided into JARs and finally deployed as a large package of EAR, while micro services open the black box and split the application into a single service. Docker technology, which does not rely on any server and data model, is a full-stack application. Each service can be deployed independently through automation. Each service runs in its own process and is contacted through a light communication mechanism, often based on HTTP resource API. These services are built on business capabilities and can achieve centralized management.

After reading the above, do you have any further understanding of the difference between SOA and micro-service architecture? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
