NoSQL Benchmark

http://blog.cubrid.org/dev-platform/nosql-benchmarking/

 

Yahoo Cloud Servicing Benchmark

 

Basic operations are Insert, Update, Read, and Scan. There are basic workload sets that combine the basic operations, but new additional workloads can also be created.

 

This article contains tests conducted on the following products and versions.

 

Cassandra-0.7.4

Although Cassandra’s latest version is 0.8.0, we have decided to use the previous version known to be stable. Because when testing with the 0.8 version, the gossip protocol between nodes malfunctioned and the node up/down information was incorrect.

 

HBase-0.90.2 (Hadoop-0.20-append)
The HBase-0.90.2 (Hadoop-0.20-append) was selected because, if not the Hadoop-append version, there may be problems on decreased durability in HDFS.

 

MongoDB-1.8.1

 

Insert, Read Only and Read and Update

 

Insert - Cassandra kills 

Read and update Cassandra beats HBase by a little 

Read Hbase wins of course but only by a little against Cassandra 

Mongo get blow out...

 

Which leads me into .. why I would love to make this event...

What is glu?

http://linkedin.github.com/glu/docs/latest/html/index.html

 

glu is a free/open source deployment and monitoring automation platform.

 

a glu agent  is running on each of those nodes

ZooKeeper is used to maintain the live state as reported by the glu agents (blue arrows)

the glu orchestration engine is the heart of the system

 

Glu Script is a Groovy Class with named closures for the actions... (can be groovy or java)

install, configure, start, stop, unconfigure and uninstall

 

The doc is pretty cool .. however, when I started getting into the state machine stuff I had to stop...

 

Orchestration .. Zookeeper to build live state, compare live and desired state.

NODE.JS AND THE JAVASCRIPT AGE

http://metamarketsgroup.com/blog/node-js-and-the-javascript-age/

 

Three months ago, we decided to tear down the framework we were using for our dashboard, Python’s Django, and rebuild it entirely in server-side JavaScript, using node.js. (If there is ever a time in a start-ups life to remodel parts of your infrastructure, it’s early on, when your range of motion is highest.)

 

This decision was driven by a realization: the LAMP stack is dead. 

 

1991-1999: The HTML Age.

2000-2009: The LAMP Age.

2010-??: The JavaScript Age.

Bootstrapping .. first round is 60M

 

-Sell itself, affordable, global, open 

-Use your own product.... Passionately use your own product...

-Measure everything... Capture everything.... even if you can’t analyze 

-Test everything... 5 users free .. raised money for charity 

-ABM...  ... always sponsor the beer at conference.. like Dyninc...

-Send stuff in the mail.. t-shirts... 

-Make everything into a campaign.. Turned hiring into a marketing campaign - .. send only 4 resumes otherwise you are black listed...

-Don’t be afraid to let your first product will fail..

FPM and Logstash and now...

 

eventmachine-tail

https://github.com/jordansissel/eventmachine-tail

 

Jordon Sissel.. 

 

This project contains two EventMachine extensions.

First, it adds an event-driven file-following similar to the unix ‘tail -f’
command. For example, you could use it to follow /var/log/messages the same way
tail -f would.

Second, it adds event-driven file patterns allowing you to watch a given file
pattern for new or removed files. For example, you could watch /var/log/*.log
for new/deleted files.

 

For logstash, the log agents were
event-driven using EventMachine. The log agents mainly get their data from
logfiles. To that end, we needed a way to treat log files as a stream.

There’s a ruby gem ‘file-tail’ that implements tailing, but not in an
event-driven way. This makes it hard to use in EventMachine programs like
logstash.

Thus, eventmachine-tail was born.

Further, the usage patterns for logstash required the ability to watch a
directory (or a file pattern) for new log files.

 

rtail -x "*.gz" "/var/log/**/*"

LexisNexis Releases Code for Its Hadoop-Killer

 

http://www.devx.com/DailyNews/Article/47281?trk=DXRSS_LATEST 

 

LexisNexis Risk Solutions' division HPCC Systems has announced that it is open sourcing the code for its High Performance Computing Cluster (HPCC) software. HPCC is a data-processing-and-delivery solution that the company is marketing as an alternative to Hadoop. HPCC includes two major components: Thor, which analyzes large datasets in a manner similar to Hadoop, and Roxie, which is closer to a traditional RBDMS or a data warehouse.

The Apache Software Foundation Announces Apache Whirr as a Top-Level Project

https://blogs.apache.org/foundation/entry/the_apache_software_foundation_announces15 

 

Apache Whirr provides a Cloud-neutral way to run a properly-configured system quickly through libraries, common service API, smart defaults, and command line tool. Whirr is being used for proof of concepts and a way to try out new Cloud services utilizing a variety of Apache products that include Hadoop, HBase, Cassandra, and ZooKeeper. An example of this is enterprise software providers Cloudera, who use Whirr to make it easy to try out their CDH product and run distributed clustered services.

Joyent arms cloud for death match with Amazon

http://www.theregister.co.uk/2011/09/15/the_new_joyent_cloud/ 

 

The pixar of cloud Jason Hoffman: Chief Scientist, Founder - PhD in Molecular Pathology

Mark Mayo: CTO... 

 

 

A month after open-sourcing what it calls "the first major hypervisor" to arrive in half a decade, cloud computing pioneer Joyent has added this hypervisor to its flagship service, allowing Linux and Windows applications onto the Joyent Cloud for the first time.

 

Joyent and its firebrand CTO told the world they had ported the KVM hypervisor from Linux to SmartOS. They promptly open-sourced the code in an effort to "make the world a better place", and now they've rolled the hypervisor into a new incarnation of the Joyent Cloud

 

The company claims that its SmartOS virtual machines are up to 14 times faster than comparable Amazon server instances

Rundeck And Nagios Nrpe Checks

http://www.dzone.com/links/r/rundeck_and_nagios_nrpe_checks.html

 

I’ve played with a few different jobs so far, including triggering Puppet runs across machines triggered by a Jenkins plugin. I’ve also been looking at running all my monitoring tasks at the click of a button (or again as part of a smoke test triggered by Jenkins) and I thought that might make a nice simple example.

My checks are written as Nagios plugins, and run periodically by Nagios. I also trigger them manually, using Dean’s NRPE runner script.

Ensemble gets some Juju!

 We figured it should represent the complexities and mystery that often surround those skilled in the DevOps field, and be something that played on the same “u” sound and etymology as Ubuntu.  Thus, “Juju” was born!
