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.
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.
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.
