2 Lessons on RabbitMQ from HighLoad – Extending the server with Plugins and HA Queues

Recently, I presented at the HighLoad++ conference in Moscow Russia. Many of the developers I spoke with were interested in two pieces of information about RabbitMQ, and I wanted to share these with a broader audience:

  • Extending through Plugins
  • High Availability Queuing

If you haven’t heard of HighLoad++, the conference is pretty special since it focuses only on high traffic websites (mostly from Russia). The main point of the conference is to talk about new architectures and approaches for highly complex systems and covers things like:

Rearview Mirror: The Evolution of Hyperic Over the Past 6 Years

An early design for mousepad giveaways from 2007 that I still use as my mousepad today.

Today is a new kind of birthday for me—it’s the day I started at Hyperic 6 years ago. It’s a journey that has been nothing short of surprising. My first meeting with then CEO Javier Soltero started the pace of what was to come: I had no idea it was an interview walking in, and was even more surprised when I walked out of that same interview accepting a job that same night. That sets the tone for the next 6 years.

It’s been an exciting journey riding the waves of technology changes these past 6 years, and sitting, in my opinion, in the perfect spot to see some of the biggest disruptors unfold.  I have literally had the privilege to work with the most interesting companies in technology along the way. Most of the biggest companies on the web, many of the biggest companies on the stock market, and some incredibly innovative startups have used our software, partnered with us, and in two cases—acquired us. From this vantage point, I have seen some impressive changes in our industry along the way. Here are some of the highlights:

Understanding App Delivery Controllers in Hybrid Clouds

Many call Application Delivery Controllers (ADC) the next generation of load balancers.  Same as load balancers, they sit in front of web servers. In addition to providing the balancing services, they now help improve scale, availability, fault tolerance, security, and routing. But, not all ADCs are delivered as pure software solutions, designed for cloud-based and virtualized deployments, or work in hybrid cloud environments—items which are becoming mainstream requirements for the Software Defined Datacenter (SDDC) that VMware sees as the future of cloud computing.

Why care about the SDDC?

VMware and Riverbed Join Forces!

Industry leaders across the board are gravitating to hybrid clouds for lower costs, no lock-in, greater flexibility, increased speed, built-in disaster recovery, and new capabilities. Of course, there are more reasons, and all these reasons are driving the need to get to a hybrid cloud model. In Sandhill.com’s recent “Leaders in the Cloud” research study from 2010 (and updated in 2011), they said, “our study surveyed more than 500 IT executives and indicated that the biggest growth will be in hybrid clouds (from 13 percent now to 43 percent in three years).”

In order to achieve the promises of hybrid clouds, VMware sees the need for a completely software driven data center so your applications are portable across disparate architectures.  By removing hardware devices, and creating application architectures where all infrastructure is virtualized, delivered as a service, and entirely automated by software, companies can now effectively move apps across clouds to meet their needs.

Escape JEE Bloat: Implement a Lightweight App Server Architecture

If you follow this blog, you know we keep hearing people talk about simplicity when discussing app servers and architectures. We certainly heard this at JavaOne and also at VMworld, but it’s been popular for a while.

The fact is that traditional Java EE (JEE) app servers bring complexity to the mix.  In addition, they are costly and consume a lot of resources. Forrester wrote Continue reading

Follow the Sun in Hyperic HQ Enterprise

Pager duty. Sigh.

For those sysadmins who manage 24/7/365, mission-critical systems, or global operations, a “follow-the-sun” model is part of the job.  But when you are NOT on duty, you would prefer not to receive any notifications.  So, an important function of alerts is the ability to alert different people depending on the schedule of who is on duty. Schedule-based alerts  are useful even in during a single shift as you can plan coverage for lunches, regular meetings or temporarily disable alerts to allow focused time to work on special projects.

With vFabric Hyperic, you can set-up “follow-the-sun” notifications in a few steps.

The High-Level Steps:

Essentially, to enable follow the sun alerting we simply need to set up roles and schedules for our sysadmins. However, those schedules are only useful when put in context of setting up an alert. So we will take you through the full process of setting up a globally enabled alert. Those steps include:

1. Decide on your Alert
2. Set Up the Condition and Action for the Alert
3. Set Up Roles with Alert Calendars (this specifies who gets noticed around the clock)
4. Set Up the Escalation Scheme

Why Application Director + Puppet Work Better Together

Lately, I have been getting questions around how vFabric Application Director and Puppet work together. Questions include:

Today, at the PuppetCon event in San Francisco, where VMware has a keynote and a session, I expect these questions will be asked more than ever as we meet Puppet’s loyal users.

Before we delve into the differences, it is important to understand the big picture. When my team started developing Application Director, open source configuration management tools like Puppet, Chef, CF Engine already existed. They were doing a great job of keeping complex applications up to date with the latest code and configurations while also helping IT to automate inventory management – a big and valuable task in any datacenter.
