Just how complex can a Login Transaction be? Answer: Very!

People in our industry always talk about IT complexity and cost. Cost is pretty easy to calculate, because IT budgets are allocated and audited every year. Complexity is very different–we know it exists, but we can’t really see or measure it. Complexity is often when our brain tries to understand something and stalls in the process, trying to make sense of information that has never been seen before.

Well, this happened to a few of us in AppDynamics last week. A customer was kind enough to share how a single login business transaction flowed across their entire infrastructure. You might be thinking: “How can a login transaction be complex? That’s just a simple call to an LDAP or SiteMinder tier”–which is pretty much what we all thought it was. However, the screenshot that graced us was one of shock, beauty and amazement. In fact, I’m looking at it right now before I scrub the customer details, and I’m still thinking “Hmmmm, this is bonkers.”

Without delaying further, here is that very screenshot showing the Login Business Transaction:

Scary huh? What you see is the flow and timing of a Customer Login business transaction as it executes across a well governed, regulated, SOA environment consisting of many services (denoted by the Java Tiers). The Customer Login transaction begins at the Java node to the right marked “START” and propagates across the entire SOA environment using a combination of sync/async JMS messages, HTTP and RMI communication to notify other Services that a customer is now active and logged in. You can also see many services writing to a database as a result of this transaction. These invocations are simply auditing the customer login to satisfy the legal regulations that this organization has to comply with. So if you ever wonder what impact Governance and Legislation has on IT, this is a perfect example of the complexity storm it creates. What’s interesting is that the Logout business transaction for this application was just as complex!

The screenshot above unfortunately reflects the enormous complexity that many IT departments have to deal with everyday, especially when a user complains that their business transaction is slow. The problem for 95% of IT departments is they don’t have this type of visibility in production. They can feel pain, but they can’t see it. A slow business transaction may take 25 seconds to complete and touch many infrastructure tiers along the way. Unless IT sees this end to end journey they’ll always struggle to troubleshoot and manage it.

The good news is you’re 30 minutes away from getting this visibility in production by evaluating a next generation application monitoring solution like AppDynamics Pro. AppDynamics will auto-discover your business transactions, map their specific flows across your infrastructure, and give you a latency breakdown across and inside every tier the business transaction touches.

To manage and master IT complexity you have to visualize and see it.  Seeing how your business actually runs across IT is completely different to guessing how your business runs across IT. Next time a user complains that their business transaction is slow, what will you do? Bury your head in a log file, or visualize how that business transaction executed using an application performance monitoring solution like AppDynamics?

Isn’t it about time you mapped your app?

In high-production environments where release cycles are measured in hours or minutes — not days or weeks — there's little room for mistakes and no room for confusion. Everyone has to understand what's happening, in real time, and have the means to do whatever is necessary to keep applications up and running optimally.

DevOps is a high-stakes world, but done well, it delivers the agility and performance to significantly impact business competitiveness.
