How-to and Performance Impact of SSL-Encrypted Replication Traffic in Galera Cluster for MySQL
+0 Vote Up -0Vote Down

August 7, 2014 By Severalnines

 

Deploying Galera Clusters across WAN environments might lead to concerns around data privacy and security - especially as more organisations are having to comply with national and international regulations. You would not want hackers eavesdropping or intercepting replication traffic. Encrypted replication hides what is sent between the Galera nodes, and makes sure each node is only communicating to the ones it trusts. But how expensive is encryption?

 

In this blog, we will show you how to encrypt the replication traffic between your Galera nodes. We will …

How to Configure ClusterControl to run on nginx
+0 Vote Up -0Vote Down

July 10, 2014 By Severalnines

ClusterControl uses the Apache HTTP Server to serve its web interface, but it is also possible to use nginx. nginx + PHP fastcgi is well-known for its capabilities to run on a small memory footprint compared to standard Apache + PHP DSO.

 

In this post, we will show you how to run ClusterControl on nginx web server by swapping out the default Apache web server installed during the initial deployment. This blog post does not mean that we officially support nginx, it just an alternative way that a portion of our users have been interested in. For instance, Phil Bayfield …

Big Data Integration & ETL - Moving Live Clickstream Data from MongoDB to Hadoop for Analytics
+1 Vote Up -0Vote Down

June 16, 2014 By Severalnines

MongoDB is great at storing clickstream data, but using it to analyze millions of documents can be challenging. Hadoop provides a way of processing and analyzing data at large scale. Since it is a parallel system, workloads can be split on multiple nodes and computations on large datasets can be done in relatively short timeframes. MongoDB data can be moved into Hadoop using ETL tools like Talend or Pentaho Data Integration (Kettle).

 

In this blog, we’ll show you how to integrate your MongoDB and Hadoop datastores using Talend. We have a MongoDB database collecting …

If you need to deploy a database cluster behind your corporate firewall, on servers with no internet access, then this blog is for you. Most of the installation tutorials out there require servers to have an internet connection, and that would not work very well with companies under strict policies and compliance guidelines. 


Our online Galera Configurator supports deployment without Internet connection for Percona XtraDB Cluster. You would need to prepare a minimum of four hosts (three DB nodes and one …

May 16, 2014 By Severalnines

We won’t bore you with buzzwords like volume, velocity and variety. This post is for MySQL users who want to get their hands dirty with Hadoop, so roll up your sleeves and prepare for work. Why would you ever want to move MySQL data into Hadoop? One good reason is archival and analytics. You might not want to delete old data, but rather move it into Hadoop and make it available for further analysis at a later stage. 

 

In this post, we are going to deploy a Hadoop Cluster and export data in bulk from a Galera Cluster using …
