Cassandra Cluster Tutorial 5 - Cassandra AWS Cluster with CloudFormation, bastion host, Ansible and the aws-command line This Cassandra tutorial is useful for developers and DevOps/DBA staff who want to launch a Cassandra cluster in AWS. The cassandra-image project has been using Vagrant and Ansible to set up a Cassandra Cluster for local testing. Then we used Packer, Ansible and EC2. We used Packer to create AWS images in the last tutorial.
Cassandra Cluster Tutorial 3: Part 2 of 2 Setting up Ansible and SSH for our Cassandra Database Cluster for DevOps/DBA Tasks This tutorial series centers on how DevOps/DBA tasks with the Cassandra Database. As we mentioned before, Ansible and ssh are essential DevOps/DBA tools for common DBA/DevOps tasks whilst working with Cassandra Clusters. Please read part 1 before reading part 2. In part 1, we set up Ansible for our Cassandra Database Cluster to automate common DevOps/DBA tasks.
Cassandra Cluster Tutorial 3: Part 1 of 2 Setting up Ansible/SSH for our Cassandra Database Cluster for DevOps/DBA Tasks Ansible and ssh are essential DevOps/DBA tools for common DBA/DevOps tasks like managing backups, rolling upgrades to the Cassandra cluster in AWS/EC2, and so much more. An excellent aspect of Ansible is that it uses ssh, so you do not have to install an agent to use Ansible. This article series centers on how DevOps/DBA tasks with the Cassandra Database.
Cloud DevOps: Using Packer, Ansible/SSH and AWS command line tools to create and DBA manage EC2 Cassandra instances in AWS. This article is useful for developers and DevOps/DBA staff who want to create AWS AMI images and manage those EC2 instances with Ansible. Although this article is part of a series about setting up the Cassandra Database images and doing DevOps/DBA with Cassandra clusters, the topics we cover apply to AWS DevOps in general - even if you don’t use Cassandra at all.
Cassandra Cluster Tutorial: Setting up Ansible for our Cassandra Database Cluster to do DevOps tasks
Cassandra Tutorial: Setting up Ansible for our Cassandra Database Cluster for DevOps/DBA tasks Ansible is an essential DevOps/DBA tool for managing backups and rolling upgrades to the Cassandra cluster in AWS/EC2. An excellent aspect of Ansible is that it uses ssh, so you do not have to install an agent to use Ansible. This article series centers on how DevOps/DBA tasks with the Cassandra Database. However the use of Ansible for DevOps/DBA transcends its use with the Cassandra Database so this article is good information for any DevOps/DBA or Developer that needs to manage groups of instances, boxes, hosts whether they be on-prem bare-metal, dev boxes, or in the Cloud.
Introduction to BigData Analytics with Apache Spark Part 1 By Fadi Maalouli and R.H. Spark Overview Apache Spark, an open source cluster computing system, is growing fast. Apache Spark has a growing ecosystem of libraries and framework to enable advanced data analytics. Apache Spark’s rapid success is due to its power and and ease-of-use. It is more productive and has faster runtime than the typical MapReduce BigData based analytics. Apache Spark provides in-memory, distributed computing.
Analytics with Apache Spark Tutorial Part 2 : Spark SQL Using Spark SQL from Python and Java Combining Cassandra and Spark By Fadi Maalouli and R.H. Spark, a very powerful tool for real-time analytics, is very popular. In the first part of this series on Spark we introduced Spark. We covered Spark’s history, and explained RDDs (which are used to partition data in the Spark cluster). We also covered the Apache Spark Ecosystem.
In this part of Spark’s tutorial (part 3), we will introduce two important components of Spark’s Ecosystem: Spark Streaming and MLlib. Display - Edit Spark Streaming By Fadi Maalouli and R.H. Spark Streaming is a real-time processing tool, that has a high level API, is fault tolerant, and is easy to integrate with SQL DataFrames and GraphX. On a high level Spark Streaming works by running receivers that receive data from for example S3, Cassandra, Kafka etc… and it divides these data into blocks, then pushes these blocks into Spark, then Spark will work with these blocks of data as RDDs, from here you get your results.
Setting up client and cluster SSL transport for a Cassandra cluster This articles is a Cassandra tutorial on Cassandra setup for SSL and CQL clients, as well as installing Cassandra with SSL configured on a series of Linux servers. Cassandra allows you to secure the client transport (CQL) as well as the cluster transport (storage transport). SSL/TLS have some overhead. This is especially true in the JVM world which is not as performant for handling SSL/TLS unless you are using Netty/OpenSSl integration.
Setting up a Cassandra cluster with cassandra image and cassandra cloud project with Vagrant for DevOps
The cassandra-image project creates CentOS Cassandra Database images for docker, virtualbox/vagrant and AWS/EC2 using best practices for Cassandra OS setup. It is nice to use vagrant and/or docker for local development. At this time it is hard to develop systemd services using Docker so we use Vagrant. Since we do a lot of that, we like to use Vagrant. Vagrant is important for developers and DevOps not to mention Cassandra DBAs.
