对于这个问题的一个答案是,首先我们会有user/kernel边界,在上面是应用程序,在下面是运行在kernel mode的程序。 其中一个选项是让整个操作系统代码都运行在kernel mode。大多数的Unix操作系统实现都运行在kernel mode。比如,XV6中,所有的操作系统服务都在kernel mode中,这种形式被称为Monolithic Kernel Design(宏内核)。

The microservices architecture does not require the “one size fits all” model of the monolithic architecture, which will generally use a single application framework and a single programming language. Decentralized Governance –one of the consequences of centralized governance is the tendency to ...
The delay problem of switching experience, but also brought about the long loading time for the first time, and the problem of the boulder application ( Monolithic ) brought by the explosion of the project; for MPA , its deployment is simple, the natural hard isolation between applications, ...
• VM-FW-R4: For both subnet-level and kernel-based virtual firewalls, it is preferable that the firewall supports rules using higher-level components or abstractions (e.g., security group) in addition to the basic 5-tuple (source/destination IP address, source/destination ports, protocol)...
In addition to better performance and a lower infrastructure footprint, containerized microservices are typically more robust than a traditional monolithic application. For example, if you deploy an entire application to a VM, when the machine goes down, the whole application goes down with it. But...
In various embodiments, the kernel of the operating system may be monolithic or may be a micro-kernel. In some embodiments, one or more operating systems may be virtual (e.g., the operating system may be a “guest” OS within a virtual machine). In such embodiments, a control transfer ...
This results in the implementation of different parts of an application in an independent way, but also allows the execution of these parts in multiple nodes which can communicate using specific well-defined interfaces, something that was not possible in monolithic architectures. These architectures ...
