《现代体系结构上的UNIX系统：内核程序员的对称多处理和缓存技术（修订版）》在揭示UNIX内核奥秘的诸多书籍中是具有里程碑意义的。在体现当今先进技术水平的系统上，采用对称多处理（SMP）技术和高速缓存存储系统来提高系统性能，已是颇为划算的重要技术。 《现代体系结构上的UNIX系统：内核程序员的对称多处理和缓存技术（修订版）》以大量示例来演示所讲述的概念，其中既有代表CISC处理器的例子，也有代表RISC处理器的例子，比如Intel 80486和Pentium、Motorola 68040和88000以及MIPS和SPARC处理器。为了增进读者对概念的理解，每一章还包含了一组练习题，在本书末尾有选择地给出了部分习题的答案。 《现代体系结构上的UNIX系统 ：内核程序员的对称多处理和缓存技术（修订版）》是为UNIX内核开发人员写的，它全面而通俗地阐述了高速缓存和对称多处理机的操作、二者协调工作的方法以及为了在融合两者的机器上运行操作系统必须要解决的问题。

Historically we have seen waves of innova on hit the Informa on Technology industry. Typically, these have happened separately in the areas of infrastructure (mainframe to distributed to virtual), applica on architecture (monolithic to client-server to n- er web) and process/methodology (ITIL). But if you look around, you will see that right now we are in the midst of what is not just another wave in one of these areas, but a complete transforma on which encompasses all three areas at once. We are watching the infrastructure space be completely disrupted by lightweight container technology (best represented by Docker). We are seeing applica on architectures moving to a distributed microservices model to allow value-added business logic to be quickly added or changed in order to be er serve the end-user. Addi onally, we are seeing bold new concepts such as “collabora on,” “failing is okay, just fail fast,” “over communicate with feedback,” take over the IT organiza on in the hot methodology trends of DevOps and con nuous delivery (CD). The really interes ng part is that these three waves are feeding on each other and amplifying the ul mate e ect on IT: the ability to provide more value faster to the business/consumer/user. In this paper, we will discuss how two of these areas (Docker and CD) are coming together to accelerate the innova on that can happen in microservices-based applica ons. This radical change in IT tooling and process has the poten al to have a huge impact on all of us. The combina on of con nuous delivery being executed on applica ons running in Docker containers will allow us to see, in enterprise IT, the exponen al growth in innova on that we have seen in consumer and mobile applica ons over the past ve years.
