Elasticsearch Server, 2nd Edition

Book Description:

This book begins by introducing the most commonly used Elasticsearch server functionalities, from creating your own index structure, through querying, faceting, and aggregations, and ends with cluster monitoring and problem diagnosis. As you progress through the book, you will cover topics such as starting Elasticsearch, creating a new index, and designing its proper structure. After that, you’ll read about the query API that Elasticsearch exposes, as well as about filtering capabilities, aggregations, and faceting. Last but not least, you will get to know how to find similar documents by using similar functionalities and how to implement application alerts by using the prospective search functionality called percolator. Some advanced topics such as shard allocation control, gateway configuration, and how to use the discovery module will also be discussed. This book will also show you the possibilities of cluster state and health monitoring as well as how to use third-party tools.

Vmware Vsphere 5.X Datacenter Design Cookbook

Book Description:

VMware vSphere 5.x provides a robust and resilient platform for virtualizing server and application workloads in datacenters. The features available in VMware’s vSphere 5.x suite of products simplify the management of resources, increase the availability of applications, and guarantee the performance of workloads deployed in the virtualized datacenters. “VMware vSphere 5.x Design Cookbook” covers the design process from creating the conceptual design, to determining the resource requirements for the logical design, and then on to creating the physical design.

“VMware vSphere 5.x Datacenter Design Cookbook” begins with the process of identifying the design factors and applying them to the logical and physical design process in order to create a successful vSphere 5.x design. The key to a successful VMware vSphere 5.x design is the design’s ability to satisfy the design factors. This Cookbook walks you through the process of identifying the design factors which include the requirements the design must satisfy and the assumptions the architect makes to form the conceptual design.

From the conceptual design, the logical design is created. The logical design process includes determining the architecture of and the resources required for the management, storage, network, and compute resources. This Cookbook includes recipes for calculating the resources required and determining the architecture and features to use while applying VMware recommended practices.

The physical design takes the logical design requirements and maps them to the physical infrastructure required to support the resources. “VMware vSphere 5.x Datacenter Design Cookbook” offers recipes to determine the physical resources and configuration required to support the logical design while satisfying the design factors. Finally, the book provides recipes for creating design documentation. Documenting the design, the implementation procedures, and the verification procedures are also covered towards the end of the book.

Introduction to Network Emulation

Book Description:

Emulation is a hybrid experimentation technique intended to bridge the gap between simulation and real-world testing. The key idea of emulation is to reproduce in real time and in a controlled manner the essential functionality of a system, so that it can interact with other real systems that can thus be evaluated. This book describes the technique of network emulation and compares it with the other experimental approaches: the scholarly analytical modeling, the popular network simulation, and the demanding real-world testing. To emphasize the practical aspects related to emulation, this book presents a large number of examples of network emulators on the market, as well as provides an in-depth analysis of a case study, the wireless network emulation testbed called QOMB.
