Because the iphone's products are based on the iOS system, which only Apple has mastered, Shanzhai vendors can only make similar interfaces and menus, and cannot actually install the system into mobile phones.
So, to identify the true and false of the iphone, is actually to identify the purchase of the machine system is true or false. Users only need to install an itunes softw

This article is based on some of our best practices in development, from the perspective of development, monitoring, and logging, we introduce some of our experience in micro-service building on the Go technology stack.

During the development of MicroServices, different modules are responsible for different developers, and clearly defined interfaces help to identify the developer's work tas
Identify HTML5 Tags:HTML5 added a number of semantically labeled tags, such as
Copy Code code as follows:
The effect came out, do not want to also know that these several browsers are not recognized these tags, so just appear a line of text: Nav aside;In modern browsers, these two are normal block-level tags, so there are line-wrapping.I risked trying to try and give Nav and aside labels a style.

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

In the CAN network, data transmission and receiving of all nodes share a bus. In the face of an unknown multi-node CAN bus network, how CAN we accurately analyze the communication protocols between nodes?

Similar to 485, CAN-Bus communicates with each other in the form of a Bus. All CAN nodes a

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

Traditional applications use local transactions and distributed transactions to ensure data consistency, but in a microservices architecture the data is private and needs to be accessed through the API provided by the service, so the distributed transaction no longer applies to the MicroServices architecture. So how does the MicroServices ar

One, micro-service selection
In the technical selection of micro-service architecture, it is the least expensive to take "no intrusion" and "community active" as the main points of view, in the future, when upgrading to atomic service architecture, Quantum service architecture, or even back to monolithic architecture.
Software development only needs to be assembled and no longer needs to be developed from s
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
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
Traditional applications use local transactions and distributed transactions to ensure data consistency, but in a microservices architecture the data is private and needs to be accessed through the API provided by the service, so the distributed transaction no longer applies to the MicroServices architecture. So how does the MicroServices architecture guarantee d

Part VII: Go microservices-service discovery and load balancing
This section deals with two basic parts of a robust microservices architecture-service discovery and load balancing-as well as how they facilitate the horizontal scaling of important non-functional requirements in 2017.
