Analytic microservices Architecture Series The article will describe the definition, characteristics, application scenarios, evolution of enterprise integration architecture and micro-service transformation thinking and technical decision-making considerations in several sections, and take IBM technology as an example to introduce how to realize the transformation of micro-service architecture. The previous article introduced the evolution of enterpri
When you choose to build your application as a microservices, you need to determine how the application client interacts with the microservices. In a single application, there is only one set of endpoints. In the microservices architecture, each microservices exposes a set of endpoints that are usually fine-grained. In
Development of a flask-based web application's user registration function (5): flask User Registration The roles are divided into two types: common users and administrator users. At least for common users, direct DB modification is not advisable and user registration is required, start the development of user registration. User table First, you need to determine what information you need to provide during u

Flask-based simple blog Project Creation (Database Operations), flask blog After the global variables are configured, copy and paste the template to the template directory. Then, we have finished the V (view) in MVC. Now we are working on M and C. M: In the global variable settings in my last essay (http://www.cnblogs.com/hachimei/p/6636654.html), there is a User class that we create tables in our own datab
Flask page, flask We will encounter such problems during our learning process, that is, we will find that paging is required during our learning process. Here, we will introduce the pagination mentioned in the book. @app.route('/',methods=['GET'])@app.route('/ This is the paging data that I read from the database. How can we paging the data? Then we need to use a separate page to save our paging-relat

In the previous code, the view function returned a string, and the content of the HTML file returned in the actual development was actually a string. Below is a summary of several ways in which flask can be used as a response. 1, response string. This has been explained earlier, but it should be noted that in fact, every time a view function responds with a status code. For example, the status code is 200, indicating that the request has been successf
many people send me e-mail, these months I have received more than 50, some asked me when the next post, some thanks to me, some encouraged me, which is really helpful to me to complete this series of articles. So I would like to thank the people who emailed me, at the same time I am also very sorry that some of the mail I reply is not too timely. I would like to thank Asim, who often takes the time to answer some of my simple questions about MicroServices
Uploading files and accessing uploaded filesHere is a picture to show how flask uploads a fileFirst, write a simple front-end page upload.html, write a file to upload the formBack-End Debug Breakpoint debuggingAfter getting to the file, of course, we need to save the file. Create a new directory under the project media to save the uploaded fileFlask also provided us with a function to detect the name of the file, recommended to use, improve security16

MicroServices are now the preferred cloud architecture component for a wide range of Internet applications, whether it's BAT or drip, or a group of micro services.Compared to microservices, traditional application architectures have the following drawbacks:1. The business code is mixed, the team members ' responsibilities are not clear, the team experience is poor and the development is inefficient.In the t
Here is an example of using Python Flask to implement a restful Web API. Small series feel very good, now share to everyone, also for everyone to make a reference.

Micro-Service ArchitectureThe birth of MicroServices is not accidental, it is the product of the rapid development of the Internet, the rapid changes in technology and the traditional architecture can not adapt to fast changes, such as the impetus of the emergence of multiple factors. In the Internet era, the products usually have two kinds of characteristics: rapid demand changes and large user groups, in this case, how to build a flexible, easy-to-e

interaction between the application modules is complex, sometimes directly accessing the counterpart module database. Databases involve too many correlated queries and slow queries, and database optimization is difficult. A single point of access to the database is critical and the failure cannot be resumed. The data replication problem is serious, causing a large amount of data inconsistency.We tried to solve the scaling problem with SQL Server always on, but the experiment found t
