Rackspace: BYOD to Your Preferred Storage
While Amazon Web Services approach is bring-your-own-data to our storage and processing solutions, Rackspace’s strategy seems to be “whatever popular NoSQL storage engine you like, we have your back. Just bring your data“.
Last month Rackspace bought MongoDB hosting provider ObjectRocket and now they acquired Exceptional Cloud Service which brings Redis hosting on board.
It’s difficult to say how well is Amazon’s strategy working as the company doesn’t do a lot to get their customers’ case studies out there—I still need to find a list of 10 companies that are using Amazon Dynamo. But this doesn’t mean a thing. On the other hand, I can see Rackspace’s strategy working and getting a lot of traction considering they’re looking after the most popular NoSQL tools.
✚ The Register writes about this acquisition too: Rackspace gobbles Exceptional Cloud Services for Redis smarts. I assume many others are asking the same question:
So, with Redis and MongoDB due to make their way into the Rackspace cloud proper, what other technologies are catching the web hoster turned cloud whisperer’s eyes?

FnordMetric: A Framework for Collecting and Visualizing Timeseries
FnordMetric looks like an interesting library for collecting and visualizing timeseries:
According to the docs, the framework has 3 components:
-
FnordMetric Classic: a DSL for processing data streams and building web-based dashboards.
It’s built in Ruby and uses Redis.
-
FnordMetric Enterprise: a JVM-based timeseries databases
-
FnordMetricUI: HTML5 and Javascript API for embeding charts into web pages. It works with either the Classic or Enterprise backends.
My only question is why building a new storage engine for the Enterprise component when there are already so many good tools for doing this. Other than that, I really liked the screenshot.

Redis - Pick the Right Data Structure
Brian O’Rourke in a post with tips about Redis:
Here’s our standard reference table for Redis datatypes, their most common uses, and their most common misuses.
Even if most of these are just common sense, it’s good to have some sort of cheat sheet around when modeling your data.

NoSQL Hosting: Redis and RavenDB
More service providers for hosted NoSQL solutions:
- Garantia Data to Offer its Redis & Memcached Hosting Services in Europe: “In-memory NoSQL Company extends Redis Cloud and Memcached Cloud to European Amazon Web Services users.”
- CloudBird Launch, now with RavenDB 2.0 support - The CloudBird Blog: “Today we’re cracking open the Champagne as we peel off the beta label and officially welcome production databases to our RavenDB hosting service. What’s more we’re also introducing support for the Raven 2.0 RTM.”
It’s not anymore just “a database for every taste”, but steadly becoming more of “a database for every taste served from anywhere you like”,

Get Your Redis on Windows with Redis Hobo
Jason Punyon about the somehow alleviated hassle of getting Redis to work on Windows using redishobo:
TL;DR: Want a virtual machine running redis in however long it takes you to download 400MB + a little completely automated install time? Follow the instructions here and you’ll be on your way.
Vagrant is great, but the user experience it’s still not awesome for a great tool like Redis. I’m wondering when Microsoft will pull themselves together to maintain a Redis fork that actually works on Windows.

Redis Partial Resynchronization PSYNC, Plus Philosophy, Trade-Offs, and Making Decisions When Creating Tools for People to Use
There are way, way too many things I’d want to quote from Salvatore’s post. They are about the philosophy of a strong product, they are about the trade-offs that go into engineering solid but friendly products, they are about making decisions and not allowing misconceptions or old bad experiences have a bad influence on what you are building. You must read it.

Using Beaver to Ship Log Files via Redis to Logstash
Beaver’s explicit goal is to provide a shipper that can be used in environments where one or more of the following is true:
- Operations cannot support the JVM on an instance
- Developers are more experienced with debugging Python performance issues
- The server does not have enough memory for a large JVM application
- Simply shipping logs to an intermediary for later processing is enough
What I’m not very clear about is the need for Redis, but I assume the main reasons could be: 1) logstash doesn’t accept pushed events; or 2) logstash might drop/lose events if pushed to0 fast.

What Is Thredis?
Gregory Trubetskoy about his Thredis project:
Thredis is Redis + SQL + Threads. Or perhaps it’s pure lunacy resulting from some mad winter hacking mixed with eggnog. Or perhaps it’s the first hybrid SQL/NoSQL server. You be the judge.
I only wish the community is not taking Redis this direction.

Using Redis for Monitoring Systems
R.I.Pienaar:
Monitoring systems generally need a number of different types of storage. These are configuration, event archiving and status and alert tracking. There are more but these are the big ticket items, of the 3 I am only going to focus on the last one – Status and Alert Tracking here.
Basically:
- record status using Redis hashes
- track staleness using Redis sorted sets
- trigger event notifications and track alerts using Redis PUB/SUB
