Overview 2.1.1 Why a Workflow Dispatching System A complete data analysis system is usually composed of a large number of task units: shell scripts, java programs, mapreduce programs, hive scripts, etc. There is a time-dependent contextual dependency between task units In order to organize such a complex execution plan well, a workflow scheduling system is needed to schedule execution; for example, we might have a requirement that a business system produce 20G raw data a day and we process it every day, Processing steps are as follows: ...

KVM back to Linux good shade Open source KVM for business?

Virtualization is the first step toward the cloud, and, similarly, open source virtualization is the first step toward an open source cloud.

Uncover the distributed cloud computing framework you don't know Mesos

Mesos Computing Framework a cluster manager, which provides efficient, resource isolation and sharing across distributed applications or frameworks, and can run Hadoop, MPI, hypertable, and Spark. Use zookeeper to implement fault tolerant replication, isolate tasks using Linux containers, and support multiple resource scheduling allocations. The Mesos contains four main types of services (actually a socket server), which are Mesos master,mesos slave,sc ...

Apache Mesos Overall Architecture

1. As with most other distributed systems, the Apache Mesos, in order to simplify the design, also employs a master/slave structure that, in order to solve the master single point of failure, makes master as lightweight as possible, and the above number It can be reconstructed through various slave, so it is easy to solve the single point of failure by zookeeper. (What is Apache Mesos?) Reference: "Unified resource management and scheduling platform (System) Introduction", this article analysis based on MES ...

A detailed comparison of HPCC and Hadoop

The hardware environment usually uses a blade server based on Intel or AMD CPUs to build a cluster system. To reduce costs, outdated hardware that has been discontinued is used. Node has local memory and hard disk, connected through high-speed switches (usually Gigabit switches), if the cluster nodes are many, you can also use the hierarchical exchange. The nodes in the cluster are peer-to-peer (all resources can be reduced to the same configuration), but this is not necessary. Operating system Linux or windows system configuration HPCC cluster with two configurations: ...

Construction of Docker Cluster management based on Kubernetes

Before the formal introduction, it is necessary to first understand the kubernetes of several core concepts and their assumed functions. The following is the kubernetes architectural design diagram: 1. Pods in the kubernetes system, the smallest particle of dispatch is not a simple container, but an abstraction into a pod,pod is a minimal deployment unit that can be created, destroyed, dispatched, and managed.   such as a container or a group of containers. 2. Replication controllers ...

The difference and connection between deep analytic openstack and KVM

OpenStack and KVM are the two most popular words in the IT world today. They are open source, and Linux are inextricably linked. But there is a big difference between the two. OpenStack: Open Source management Project OpenStack is an open source project designed to provide software for public and private cloud building and management. It is not a software, but a combination of several major components to accomplish some specific work. OpenStack is composed of the following five relatively independent components: OpenStack comput ...
