Mastering Mesos

By: Dipa Dubhashi, Akhil Das

Overview of this book

Apache Mesos is open source cluster management software that provides efficient resource isolations and resource sharing distributed applications or frameworks. This book will take you on a journey to enhance your knowledge from amateur to master level, showing you how to improve the efficiency, management, and development of Mesos clusters. The architecture is quite complex and this book will explore the difficulties and complexities of working with Mesos. We begin by introducing Mesos, explaining its architecture and functionality. Next, we provide a comprehensive overview of Mesos features and advanced topics such as high availability, fault tolerance, scaling, and efficiency. Furthermore, you will learn to set up multi-node Mesos clusters on private and public clouds. We will also introduce several Mesos-based scheduling and management frameworks or applications to enable the easy deployment, discovery, load balancing, and failure handling of long-running services. Next, you will find out how a Mesos cluster can be easily set up and monitored using the standard deployment and configuration management tools. This advanced guide will show you how to deploy important big data processing frameworks such as Hadoop, Spark, and Storm on Mesos and big data storage frameworks such as Cassandra, Elasticsearch, and Kafka.

Containers


A Linux Container, (referred to simply as container for the rest of this chapter) allows applications to run on an allocated share of resources within an isolated, individual environment. Since all containers share the Operating system (OS) of the host machine and do not require the OS to be loaded up, they can be created in a matter of seconds.

Container technology, based on operating system level virtualization, has been present for over a decade now. OS level virtualization is a method by which an OS kernel allows creation of many user namespace instances (also called containers) instead of only one.

We can look at containers as encapsulated, individually deployable components running as isolated instances on the same kernel. Containers have a big advantage over traditional technologies such as bare metal, meaning servers with an operating system or virtualized environments such as Microsoft Hyper-V. From a developer's point of view, we can just package our application and dependencies...
