其概念是非常简单的：通过使用整个软件栈(操作系统、应用、配置数据等等)的虚拟映像来避免安装与配置上的冲突。
The concept is simple: avoid all installation and configuration hassles by using a virtual image of an entire software stack: operating system, application (s), configuration data, etc.

这一层提供了一组通用函数供底层网络设备驱动程序使用，让它们可以对高层协议栈进行操作。
This layer provides a common set of functions to be used by lower-level network device drivers to allow them to operate with the higher-level protocol stack.
但是，由于其专用特性，整个软件栈(包括操作系统)都是高度定制的，或者说，它的规模是针对预定用途适当设置的。
However, due to its purpose-built nature, the entire software stack (including the operating system) is highly customized or "right-sized" for its intended use.
与其他计算平台一样，WebSphereDataPower也拥有一个软件栈，其中包括操作系统和用于实现一个功能集的软件组件。
Like any other computing platform, WebSphere DataPower has a software stack, which includes operating system and software components that implement a set of capabilities.
这些栈都是从操作系统分配给Domino的2GB内存中分配的，因此Domino 6可以支持的NRPC用户的数量就限制为3000。
These stacks are allocated from the 2 GB of memory that the operating system gives Domino, thereby limiting the number of NRPC users Domino 6 can support to 3000.
指令push和QUEUE对应的是对栈的LIFO和FIFO操作。
The instructions PUSH and QUEUE correspond to LIFO and FIFO operations on the stack.
调用栈的检查在遇到PrivilegedAction实例时停止，有效地将执行指定操作所必需的许可权授予所有的后继类调用。
The check of the calling stack stops when it encounters a PrivilegedAction instance, effectively granting all subsequent class calls the required permission to perform the specified operation.
有限的互操作性测试(每个客户端使用一个栈，服务器使用另一个，只尝试WS - SecureConversation测试)会显示更多的问题。
Limited interoperability testing (using one stack for the client and another for the server, only tried for the WS-SecureConversation tests) demonstrated even more issues.
这种情况造成严重的可互操作性问题，因为不能保证各种栈可以支持相同的选择。
This situation creates major problems for interoperability, because there's no guarantee that different stacks support the same choices.
这个互操作性测试有助于在各个栈之间建立基本水平的兼容性，但是收效甚微，因为只有少量配置被测试。
This interoperability testing has helped establish a basic level of compatibility among stacks, but the benefits have been limited because of the small number of configurations tested.
这种简单的设计，很有可能是考虑到数据操作都符合后进先出（LIFO ）规则，这意味着访问栈的内容并不需要复杂的数据结构，一个简单的栈顶指针就能搞定一切。
This simple design, possible because the data obeys strict LIFO order, means that no complex data structure is needed to track stack contents - a simple pointer to the top of the stack will do.
通过选择一个调试目标，或者调试视图中的任意其构件(例如，线程、栈框架)，可以激活一个调试操作。
A debug session is made active by selecting the debug target, or any of its components (for example, threads, stack frames) in the debug view.
在程序的正常操作过程中，当调用一个函数时，被调用函数的所有参数以及返回位置的指针都放在栈中。
During normal operation of a program, when a function is called, any arguments for the called function along with a pointer to the return location are placed onto the stack.
FSH在协议层操作，不提供限制网络资源的能力，这样，没有一个应用程序能垄断网络栈。
The FSH operates at the protocol layer and does not provide the ability to constrain network resources such that no one application can monopolize the network stack.
协议栈的 TCP层聚合了两次写操作。
Rexx中有一些指令可以显式地指定要操作的栈；但是其他指令操作是在您用ADDRESS指令配置的环境中进行。
Some instructions in Rexx may explicitly specify a stack to operate on; but other instructions operate within an environment which you configure with the ADDRESS instruction.
名为Cylon的调试器提供了人们所能想到的所有特性：传统的断点、基于异常的断点、调用栈、监视器以及变量的查看和操作。
The debugger - called Cylon - provides all the features one could expect: conditional breakpoints, breakpoints on exceptions, call stack, watches, the exploration and manipulation of variables.
除此之外，每个栈的开发人员响应源自用户遇到的安全性配置或者互操作性问题的bug报告。
Other than that, the developers for each stack respond to bug reports from users encountering security configuration or interoperability issues.
在本文中，您将首先更多地了解web服务栈之间互操作性的安全问题。
In this article, you'll first learn more about the issues of security interoperability among web services stacks.
WSO2完成软件组件间的所有集成，并测试了组件栈的功能以及与其他Web服务容器的互操作性。
WSO2 does all the integration between the software components and tests the stacks' functionally and interoperability with other web service containers.
在传统的语言中，这样的递归需要连续不断的入栈操作，以维护调用的历史；而在Scheme中，却不是这样。
In traditional languages, this recursion eats away at the stack to maintain a history of the calls; in Scheme, it's different.
通过网络栈进行的通信都需要对socket进行操作。
Communication through the network stack takes place with a socket.
为了能够将操作作为Subject执行，必须在调用堆 栈中将 Subject引入（或者注入）ProtectionDomain 。
In order to be able to perform the action as the Subject, the Subject must be introduced (or injected) into the ProtectionDomains on the call stack.
在操作系统方面，Microsoft正在. NET服务器(目前是beta测试版3)方面努力，. NET服务器集成了对Web服务协议栈(包括UDDI)的本地支持。
On the operating system side, Microsoft is working on a.net server (currently beta 3), which integrates native support for the Web services stack, including UDDI.
