microservices scalability

called in the method, no lock is held, that is, the lock is run out and released quickly . This is why it is not advocated directly with synchronized direct modification method of the most important reason. I want to get which lock, I get, run out, hurriedly release, even if a few lines of code I still need to use this lock, I will not occupy this lock for a second. This can only be said to be a good programming habit, but it can avoid lock sequence deadlocks as much as possible.Second, perform

Many programmers spend a lot of time tuning application-level performance bottlenecks as they address JVM performance issues, and when you finish reading this series you will find that I might look at this kind of problem more systematically. I've said that the JVM's own technology limits the scalability of Java enterprise-class applications. First, let's start by listing some of the leading factors. The mainstream hardware server provides a

In terms of scalability, customers' requirements become more and more, and 20, 50, or even more than 100 requirements appear on the function list. However, in general, we can shorten them to five categories and solve the scalability problem through five ways:1. Adjust query operations The optimization of queries will allow you to get the most results with the least effort. Make full use of the query functio

Scalability is a design indicator for the computing and processing capabilities of software systems. high scalability represents elasticity. In the process of system expansion and growth, the software can ensure vigorous vitality, with few changes or even the addition of hardware devices, the processing capability of the entire system can be linearly increased to achieve high throughput and low latency and

Abstract: This article focuses on how to understand the extension of Java applications and different types of extension techniques and specific techniques, and introduces some general extension strategies for Java enterprise applications.To be honest, "extensibility" is a comprehensive and detailed topic that is often not fully understood. It is generally thought that extensibility is synonymous with high availability, and I have seen programmers and architects "veteran" recommend clustering as

The scalability of the Web site is designed to allow for the ability to continuously expand and enhance the system's capabilities with minimal impact on existing systems. Here is a detailed description of the "extensibility" and "scalability" concepts that are easy to confuse: Extensibility Performance: infrastructure does not need to change frequently, applications are less dependent or coupled, and can re

Micro-Service "microservices" has become one of the most popular hot words in software architecture. There are a lot of articles about microservices on the web, but it feels a lot too far away from us, and we don't find many instances that really apply in enterprise scenarios. Omitted here 10,000 words ~ ~ ~ so want to use their recent period of time using micro-services and by looking at the masters of the

Abstract: sentinel provides a variety of SPI interfaces to provide scalability. You can expand the interface implementation based on the same Sentinel-core, so that you can easily add custom logic to Sentinel. In order to unify the initialization process, the initialization logic extension mechanism abstracts some initialization logic of the initfunc interface, for example, registering a dynamic rule source (example) to register the statisticslot call

Mono 3.8.0 was released on September 10, September 4. The runtime of this version brings some performance and scalability improvements, and completes the migration to the Windows platform. Mono follows the gnome and Linux kernel version numbering policies, meaning that 3.8 is a major stable version after 3.6 (released last month. This version improves performance: JIT can better deal with the remainder operation of the long type with the power of di

business reputation and potential customer loss. Global enterprises operate across time zones to provide around-the-clock business services. The scheduled maintenance window for system maintenance and upgrade no longer exists. Distributed enterprises must be able to provide similar services in each geographic location and avoid network faults or transmission time. Reliability, availability, and scalability a solution implements some or all aspects of

basic functionality from thread security, Collections.synchronizedmap allows users who need synchronization to have synchronization, while users who do not need synchronization pay a price for synchronization.The simple approach taken by Hashtable and Synchronizedmap to get synchronization (each method in a synchronous Hashtable or in a synchronized Map wrapper object) has two major deficiencies. First, this approach is a barrier to scalability becau

What is micro-service?The traditional single service architecture is a separate service package, sharing code and data, development cost is high, maintainability, scalability is poor, technology transformation, cross-language cooperation is relatively difficult. While the MicroServices architecture emphasizes that a service is responsible for a business, the service can be deployed separately, the technolog
