Jvm-sandboxJVM-SANDBOX,JVM sandbox container, a non-intrusive run-time AOP solution based on the JVM.
Core features of Jvm-sandbox:
Real-time non-intrusive AOP framework
In the common AOP framework implementation, there are two kinds of static weaving and dynamic weaving.
Static KnittingStatic weaving occurs when bytecode is generated, and the AOP bytecode is inserted into the target class and method in advance according to the rules of certain framework, and AOP is realized.
Dynamic WeavingDynamic weaving allows AOP bytecode enhancement for the specified method to be completed while the JVM is running. Most of the common dynamic weaving schemes use the renaming of the original method, and then create a new signature method to perform the function of AOP (common implementations such as CGLIB), but there are some application boundaries in this way:
Invasive
The target class of the agent needs to be invaded. For example, in spring, it must be a Bean that is hosted in a spring container.
Curing Resistance
The target agent method is cured after startup and cannot be re-augmented with an existing method

Characteristics
Elegant and beautiful: Design patterns are well-designed based on ANT's design system: typical pages and scenarios for refining from mid-background applications The latest technology stack: Developing responses with front-end technologies such as REACT/DVA/ANTD: Design themes for different screen sizes: configurable themes to meet diverse brand demands Internationalization: Built-in industry-ready International solutions Best Practices: Good Engineering practices help you consistently produce high-quality code Mock data: Practical on-premises data debugging scenarios UI testing: Automated testing to ensure front-end product quality JDBC Connection pool, monitoring component DruidDruid is a JDBC component that consists of three parts:
Druiddriver Agent driver, can provide a plug-in system based on Filter-chain mode.  Druiddatasource an efficient and manageable database connection pool. What Sqlparser Druid can do.
1) Can monitor database access performance, Druid built-in provides a powerful statfilter plug-in, the ability to detailed statistics of SQL execution performance, which is useful for online analysis of database access performance.
2) Replace DBCP and C3P0. Druid provides an efficient, powerful, and scalable database connection pool.
3) database password encryption. Write the database password directly in the configuration file, this is bad behavior, easy to lead to security issues. Both Druiddruiver and Druiddatasource support PasswordCallback.
4) SQL execution log, Druid provides different logfilter to support common-logging, log4j and Jdklog, you can select the appropriate logfilter as needed to monitor your application's database access.
Extending JDBC, if you want to have programming requirements for the JDBC layer, you can easily write extensions to the JDBC layer through the filter-chain mechanism provided by Druid.

The following is a monitoring implementation based on the Druid built-in extension statfilter:

Ali pouch is not a completely innovative technology. First, Ali based on LXC technology for the group's business to provide container services, 2011, Ali Self-research container technology t4,2016 years, Ali inside the container technology renamed to Pouch, and in the last year to support a large number of core business within the group, such as e-commerce platform core business, major applications and some databases, Ant Gold Clothing payment business, Taobao trading business and so on.
The origin of the naming of pouch, which originated from Ali as an open-minded person, pays attention to the original intention of user scene application. As Alibaba technology expert Liang said, pouch as a large-scale scene from the Alibaba Group self-research technology, compared to Docker, Rkt and other container technology, the core value of differentiation is reflected in the following aspects:
Rich container technology: The application experience inside the container, such as virtual machine, has the init process, and is rich in system services, rich isolation protection: Isolation security can not avoid, kernel hardening and lightweight virtual machine support, enrich the isolation dimension; peer-to-image distribution: Image distribution in ultra-large-scale scenes, to alleviate network load; Kernel compatibility: Enterprise kernel upgrades tend to be slower and optimally adapted to the existing underlying infrastructure.Open Source Database AlisqlAlisql is a branch of the official MySQL version that is maintained by the Alibaba Cloud Database team and is currently used for Alibaba Group business as well as Alibaba Cloud database services.
