patches, resulting in increasing technical debt. If the software version used does not provide maintenance, it can only be implemented by a specific person or team or the whole application rewrite method. This is very common in actual application development, large companies such as Microsoft cannot avoid this problem, which will lead to related risks.
In the above section, we analyze the advantages and problems of the monolithic architecture based on the problems encountered in actual applic
MySQL database on azure is the MySQL cloud databases service launched on the Azure platform, providing users with a fully-managed, fast-deployable, highly available, high-security database service with full MySQL protocol compatibility. Customers can use common MySQL-enabled platforms and technologies for development and integration. This article demonstrates how to use the MySQL EntityFramework component to operate MySQL PaaS DB.System Environment/Ap

In the previous chapter, I described how we can use the web role and worker role of Azure PAAs to handle complex business logic-web role can quickly respond to front-end business requests and save input to the Azure Storage queue-worker role reads data from the queue and can handle complex business logic on the backend-As you can
If you are a webmaster, want to build a website. Without cloud services, you need to invest in a server, install Server software, and write Web programs.Now you're following the trend, using popular cloud computing,If you're using IaaS services, it means you don't have to buy your own servers and buy virtual machines anywhere, but you still need to install your own server software.And if you use PAAs services, it means that you do not need to buy a se

Recently done several projects, the platform is becoming more and more serious, even the end of the direct and platform interaction, may be the front end is only the skin and layout is their own, even the skin is unification.
Then we associate it with the concept of SaaS.
Server-side call platform is actually a SaaS, but it's not thorough enough.
Bicycle unified cashier, in order to avoid brand exposure, the interface to do their own, but also a kind of SaaS, as long as the request sign signa

Sequential stacks: Use a continuous set of memory to save the data in the stack, and define a top variable to hold the stack number.
The stack structure is the "LIFO" principle.
The most basic operation of the stack is two: push (into stack) + pop (out of

NET Framework, we should still understand them to optimize our applications. At the same time, we also need to have some basic knowledge of memory management mechanisms, which can help to explain the behavior of variables in our daily program writing. In this article, I will explain the basic knowledge of sta

What is the difference between stack and stack? Why is stack speed fast and stack speed slow?
Both stacks and stacks are places where Java is used to store data in Ram. Unlike C ++, Java automatically manages stacks and stacks, and programmers cannot directly set stacks or stacks.

Sequential stack: A set of contiguous storage units from the bottom of the stack to the top of the data element, and due to the particularity of the stack operation, also must be attached to a position pointer top (stack top pointer) to dynamically indicate the position of the stac
