Create a Basho Riak Cluster on GoGrid

Monday, July 9th, 2012 by

Basho is a GoGrid partner and responsible for the open-source Riak project. If you are not familiar with Riak, it is a well regarded open-source distributed database. It was built off of the Dynamo concept so it is often compared to Cassandra and Amazon Dynamo DB.

Riak is used as a fast, fault-tolerant distributed database. Companies like Mozilla use it for storing and analyzing beta testing results. Mozilla needed a solution to help improve the user experience and that would allow them to store large amounts of data very quickly. Another example of a company using Riak is Bump which uses Riak to scale and manage massive amounts of data sent between it’s millions of users. Riak is used to store elements of past user conversations so that communication history is readily accessible to users.

Basho Riak version 1.1.4 is now available as a GoGrid Community Server Image (CGSI). You can find it when you launch a virtual machine and search for “Riak”. This image is available in all our data centers. This CGSI contains the open source version so support is only available via the community site and will not have all the features present in the Enterprise version. However, you can use this image to either run a proof of concept (POC) of Riak to see if it will meet your needs or to run a small cluster. These will run on GoGrid’s high performance VMs which have been shown to have significant performance advantages over other cloud implementations.

Speeding Things Up in the Cloud with NGINX

It’s been no secret to us in the high-performance, web server in-crowd that NGINX (pronounced “engine-x”) has been taking the webhosting world by storm for the last several years; *sites like WordPress, Facebook, Hulu, Github, SourceForge and more have been offloading some or many functions onto NGINX. I had originally been exposed to NGINX whilst researching for a higher-performance web server that was 64-bit friendlier than Apache, and that was did not use single threads. Apache has an enormous memory footprint on 64-bit systems and is a single-threaded application.

NGINX is a very flexible HTTP server that can also serve as a reverse proxy, load balancer, caching server, and an IMAP/POP3 proxy. Unlike Apache, however, the configuration is a little bit more involved and can be a big change for Apache loyalists.

In this is example, NGINX will be configured as a full webserver with PHP support. My goal when conjuring this project was to make a pre-configured Community GSI on the GoGrid Exchange with as little modification as possible to ensure a “pure” environment. If you’re anything like me, you might tremble at the thought of even using a typical, pre-configured server with a LAMP stack; I personally like setting things up from scratch, but there’ve been plenty of situations where I would’ve preferred a pre-configured solution. Hopefully I can capture the essence of my intentions.

One thing I should note before I get started is that NGINX does not have a module for PHP the way Apache does; PHP must be run using the FastCGI methodology. Much like the way you would pass requests to a Java container or reverse proxy, so must we for PHP.

The first thing I should mention is that I’m using the EPEL and IUS repositories to for the latest versions of NGINX and PHP-FPM. IUS is the official repository for RHEL/CentOS as referenced by PHP.net. Using these 2 repositories will not alter any existing packages on your system.

How To Set Up Private IP Segregation with CloudPassage in the GoGrid Cloud

Thursday, September 29th, 2011 by

CloudPassage is a key security partner that has images available on the GoGrid Partner Exchange. The CloudPassage images on GoGrid come pre-installed with their Halo daemon. This is available on CentOS, Debian, Red Hat, and Ubuntu on both 32-bit and 64-bit flavors. Alternately, you can launch a GoGrid base image and install the Halo daemon on your own. This tutorial assumes that you have a basic understanding of Linux and SSH as well as basic firewall strategies. It also assumes that you know how to configure private IPs so that will not be covered here.
