It’s been a week since we hosted AppJam Americas, our first North American user conference in San Francisco. With myself as master of ceremonies, and a minor wardrobe malfunction at the start (see video at the end of this post), the entire day was a huge success for us and our customers. One thing that stuck in my mind was that applications today have become way more complex to manage—and strategic monitoring has become key to mastering that complexity. Simply put, SOA+Virtualization+Big Data+Cloud+Agile != Easy.
The day started with Jyoti Bansal, our CEO and Founder outlining his vision to be the world’s #1 solution for managing modern web applications. The simple facts are that applications have become more dynamic, distributed and virtual. All of these factors have increased their operational complexity, and log files and legacy monitoring solutions are ill-suited to the task.
Jyoti then outlined our core design principles around Business Transaction Monitoring, Self-learning, intelligence and the need to keep app management simple. He then suggested what the audience could expect from AppJam: “AppJam is about sharing knowledge, learning best practices, guiding our direction and Jamming.” (We’re pretty sure by “jamming” he meant “partying.”)
With the intro from Jyoti done, it was time for me to nose dive the stage and introduce our first customer speaker – Ariel Tsetlin from Netflix.
How Netflix Operates & Monitors in the Cloud
With 27 million customers around the world, Neflix’s growth over the past three years has been meteoric. In fact, they found that they couldn’t build data centers fast enough. Hence, they moved to the public cloud in AWS for better agility.
In his session, Ariel talked about Netflix’s architecture in the cloud and how they built their own PaaS in terms of apps and clusters on top of Amazons IaaS. One unique thing Netflix does is bake their OS, middleware, apps and monitoring agents into a single image rather than using a tool like Chef or Puppet to manage application configuration and deployment separately from the underlying OS, middleware and tools. Everything is automated and managed at the instance level, with developers given the freedom and responsibility to deploy whenever they want to. That’s pretty cool stuff when you consider that developers now manage their own capacity and auto-scaling within the Cloud.
Ariel then talked about the assumption that failure is inevitable in the Cloud, with the need to plan and design around the fact that every part of the application can and will fail at some point. Testing for failure through “monkey theory” and Netflix’s “Simian Army” allows them to simulate failure at every level of the application, from randomly killing instances to taking out entire availability zones in AWS.
From a monitoring perspective, Netflix uses internally developed tools and AppDynamics, which are also baked into their AWS images. Doing so allows developers to live and die by monitoring in production through automated alerts and problem discovery. What’s perhaps different is that Netflix focuses their monitoring at the service level (e.g. app cluster), rather than at the infrastructure level–so they’re really not interested in CPU or memory unless it’s impacting their end users or business transactions.
Finally, Ariel spoke about AppDynamics at Netflix, touching on the fact they monitor over 1 million metrics per minute across 400+ business transactions and 300+ application services, giving them proactive alerts with URL drill-down into business transaction latency and errors from self-learned baselines. Overall, it was a great session for those looking to migrate and operate their application in the Cloud.
When Big Data Meets SOA
Next up was Bob Hartley, development manager from Family Search, who gave an excellent talk about managing SOA and Big Data behind the world largest genealogy architecture. With almost 3 billion names indexed and 550+ million high resolution digital images, FamilySearch has over 20 petabytes of data which needs to be managed by their Java and Node.JS distributed architecture spanning 5,000 servers. What’s scary is that this architecture and data is growing at a rapid pace, meaning application performance and scalability is fundamental to the success of Family Search.
After a brief intro, Bob started to talk about his Big Data architecture in terms of what technologies they were using to manage search queries, images, and people records. Clusters of Apache Lucene, SOLR, and custom map-reduce combined with traditional relational database technology such as Oracle, MySQL, and Postgres.
Bob then talked about his team’s mission – to enable business agility through visibility, responsiveness, standardization, and vendor independence. At the top of this list was to provide joy for customers and stakeholders through delivering features that matter faster.
Bob also emphasized the need for repeatable, reliable and automated processes, as well as the need to monitor everything so his team could manage the performance of their SOA and Big Data application through continuous agile release cycles. Family Search has gone from a 3-month release cycle to a continuous delivery model in which changes can be deployed in just 40 minutes. That’s pretty mind blowing stuff when you consider the size and complexity of their environment!
What’s interesting is that Release != Deploy at FamilySearch; they incrementally roll out out new features to different sets of users using flags, allowing them to test and tease features before making them available to everyone. Monitoring is at the heart of their continuous release cycle, with Dev and Ops using baselines and trending to determine the impact of new features on application performance and scalability.
In terms of the evaluation process, the company looked at 20 different APM vendors over a 6 month period before finally settled on AppDynamics due to our dynamic discovery, baselining, trending, and alerting of business transactions. As Bob said, “AppDynamics gave us valuable performance data in less than one day. The closest competitors took over 2 weeks just to install their tools.”
Today, a single AppDynamics management server is used in production to monitor over 5,000 servers, 40+ application services, and 10 million business transactions a day. Since deployment, Family Search has managed to find dozens of problems they’ve had for years, and have managed to scale their application by 10x without increasing server resources. They’ve also seen MTTD drop from days to minutes and MTTR drop from months to hours and minutes.
Bob finished his talk with his lessons learned for managing SOA, Big Data and Agile applications: “Keep Architecture Simple,” “Speed of delivery is essential,” “Systems will eventually fail,” and “Working with SOA, Big Data and Agile is hard.”
How AppDynamics is accelerating DevOps culture at Edmunds.com
After lunch, John Martin, Senior Director of Production Engineering, spoke about DevOps culture at Edmunds.com and how AppDynamics has become central to driving team collaboration. After a brief architecture overview outlining his SOA environment of 30 application services, John outlined what DevOps meant to him and his team – “DevOps is really about Collaboration – the most challenging issues we faced were communication.” Openly honest and deeply passionate throughout his session, John talked about three key challenges his team faced over the years that were responsible for the move to DevOps:
1. Infrastructure Growth
2. Communication Failure
3. Go Faster & Be Efficient
In 2005 Edmunds.com had just 30 servers; by the end of this year that figure will have risen to 2,500. Through release automation using tools such as Bladelogic and Chef, John and his team are now able to perform a release in minutes versus the 8 hours it took back in 2005.
John gave an example on communication failure in which development was preparing for a major release at Edmunds.com using a new CMS platform. This release was performance-tested just two weeks prior to go-live. Unfortunately the new platform showed massive scalability limitations, causing Ops to work around the clock to over-provision resources as a tactical fix. Fortunately the release was delivered on time and the business was happy. However, they suffered as a technology organization due to finding architecture flaws so late in the game – “We needed a clear picture of what went wrong and how we were going to prevent such breakdown in future.”
Another mistake with a release in 2010 which forced a major re-think between development and operations. It was this occurrence that caused Edmunds.com to get really serious about DevOps. In fact, the technical leads got together and reorganized specialized teams within Dev and Ops to resolve deployment issues and shed pre-conceptions on who should do what. The result was improved relationships, better tooling, and a clearer perspective on how future projects could work.
John then touched on the tools that were accelerating DevOps culture, specifically Splunk for log files and AppDynamics for application monitoring. “AppDynamics provides a way for Dev and Ops to speak the same language. We’ve saved hundreds of hours in pre-release tests and discovered many new hotspots like the performance of our inventory business transaction which increased by 111%.” In fact, within the first year, AppDynamics generated a ROI of $795,166 with year 2 savings estimated at a further $420k. John laughed, “As you can see, AppDynamics wasn’t a bad investment.”
John ended his session with 5 tips for ensuring that DevOps succeeds in an organization: Be honest, communicate early and often, educate, criticize constructively, and create champions. Overall, a great session on why DevOps is needed in today’s IT teams.
Zero to Production APM in 30 days (while sending half a billion messages per day)
The final customer session of the day came from Kevin Siminski, Director of Infrastructure Operations at ExactTarget and it was definitely worth waiting for. Kevin actually kicked off his talk by describing a weekly product tech sync meeting which he had with his COO. The meeting was full with different stakeholders from development and operations who were discussing a problem that they were currently experiencing in production.
“I literally got my laptop out, brought up the AppDynamics UI and in one minute we’d found the root cause of the problem,” Kevin said. Not a bad way to get his point across of why the value of Application Performance Management (APM) in 2012 is so important.
Kevin then gave a brief intro to ExactTarget and the challenges of powering some of the world’s top brands like Nike, BestBuy and Priceline.com. ExactTarget’s .NET messaging environment is highly virtualized with over 5,000 machines that generate north of 500 million messages per day across multiple Terabytes of databases.
Kevin then touched on the role of his global operations team and how his team’s responsibility had shifted over the last four years. “My team went from just triaging system alerts to taking a more proactive approach on how we managed emails and our business. Today my team actively collaborates with development, infrastructure and support teams.” All these teams are now focused and aligned on innovation, stability, performance and high availability.
Kevin then outlined his 30-day implementation plan for deploying AppDynamics across his entire environment using a single dedicated systems engineer and an AppDynamics SaaS management server for production. Week 1 was spent on boarding the IT-security team, reviewing config mgmt and testing agent deployment to validate network and security paths. Week 2 involved deploying agents to a few of the production IIS pools and validating data collection on the AppDynamics management server. Week 3 saw all agents pushed to every IIS pool with collection mechanism sent to disabled. The config mgmt team then took over and “owned” the deployment process for go live. Week 4 saw all services and AppDynamics agents enabled during a production change window with all metrics closely monitored throughout the week to ensure no impact or unacceptable overhead.
AppDynamics’ first mission was to monitor the ExactTarget application as it underwent an upgrade to its mission-critical database from SQL Server 2003 to 2008. It was a high-risk migration as Kevin’s team were unable to assess the full risk due to legacy application components, so with all hands on the deck they watched AppDynamics as the migration happened in real-time. As the switch was made, application calls per minute and response time remained constant but application errors began to spike. By drilling down on these errors in AppDynamics, the dev team was quickly able to locate where they were coming from and resolve the application exceptions.
Today, AppDynamics is used for DevOps collaboration and feedback loops so engineers get to see the true impact of their releases in a production environment, a process that was requested by a product VP outside of Kevin’s global operations team. Overall, Kevin relayed an incredible story of how APM can be deployed rapidly across the enterprise to achieve tangible results in just 30 days.
A nice surprising statistic that I later realized in the evening was that the total number of servers being monitored by AppDynamics across our four customer speakers was well over 20,000 nodes. Having been in the APM market for almost 10 years I’m struggling to think of another vendor with such successful large scale production deployments.
Here’s a link to the photo gallery of AppJam 2012 Americas. A big thank you to our customers for attending and we’ll see you all next year!

Many people recognize DevOps as an enormous benefit – faster application deployment, automated toolchains, support of more granular updates, better cooperation across groups. However, less appreciated is the journey enterprise IT groups need to make to achieve this outcome. The plain fact is that established IT processes reflect a very different set of goals: stability, infrequent change, hands-on administration, and alignment with ITIL. So how does an enterprise IT organization implement change...

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

There’s a lot of discussion around managing outages in production via the likes of DevOps principles and the corresponding software development lifecycles that does enable higher quality output from development, however, one cannot lay all blame for “bugs” and failures at the feet of those responsible for coding and development. As developers incorporate features and benefits of these paradigm shift, there is a learning curve and a point of not-knowing-what-is-not-known. Sometimes, the only way ...

Over the years, a variety of methodologies have emerged in order to overcome the challenges related to project constraints. The successful use of each methodology seems highly context-dependent. However, communication seems to be the common denominator of the many challenges that project management methodologies intend to resolve. In this respect, Information and Communication Technologies (ICTs) can be viewed as powerful tools for managing projects. Few research papers have focused on the way...

As the world moves from DevOps to NoOps, application deployment to the cloud ought to become a lot simpler. However, applications have been architected with a much tighter coupling than it needs to be which makes deployment in different environments and migration between them harder.

How can you compare one technology or tool to its competitors? Usually, there is no objective comparison available. So how do you know which is better? Eclipse or IntelliJ IDEA? Java EE or Spring? C# or Java? All you can usually find is a holy war and biased comparisons on vendor sites. But luckily, sometimes, you can find a fair comparison. How does this come to be? By having it co-authored by the stakeholders. The binary repository comparison matrix is one of those rare resources. It is edite...

I’ve been thinking a bit about microservices (μServices) recently. My immediate reaction is to think: “Isn’t this just yet another new term for the same stuff, Web Services->SOA->APIs->Microservices?” Followed shortly by the thought, “well yes it is, but there are some important differences/distinguishing factors.” Microservices is an evolutionary paradigm born out of the need for simplicity (i.e., get away from the ESB) and alignment with agile (think DevOps) and scalable (think Containerizati...
