Containers enable rapid deployment of new applications and represent one of the hottest trends in the IT development community today. However, to implement a container deployment production environment, IT staff also need to use SDN technology to enable scalable, manageable, and secure communication between distributed, micro-applications. What is a container? Containers can speed up application migration a

01. Carefully select the container type Select the container principle: you need to consider the ordering of the elements, whether it is consistent with the criteria, iterator capabilities, element layout, compatibility with C, lookup speed, reference count, insert Delete support for the semantics of things, whether some operations will invalidate iterators, memory allocation policies.

IoC container summary and simple Simulation When a component requires external resources, the most direct and wise way is to perform a search. This behavior is called active search. However, this kind of search has a disadvantage: components need to know how to obtain resources. A good solution for obtaining resources is to apply IoC (Inversion of Control, Control reversal ). Its idea is to reverse the direction of resource acquisition. The traditiona

about IOC It is believed that the IOC and the Bean are the most commonly heard two nouns when learning spring, and that the frequency with which the IOC is learning spring must have its reasons. If we make a metaphor, the bean is the main actor in spring, then the IOC is the stage where the protagonist performs, without the IOC as the Bean's bearer, then the bean will not shine in programming. As an important member of the spring core component, understanding its internal implementation is quit
