How Microeconomics Help Boost Application Performance - Part II
In my last post, I talked about how I keep my approach to application performance simple – I use my one semester’s worth of microeconomics knowledge to continuously evaluate the supply and demand sides of my application architecture. What can go wrong, right?
One of the points we’ll explore further in this post is that supply shouldn’t be viewed simply as a measure of hardware capacity. Better to view supply as that which is demanded (see what I did there…?). In a complex environment, supply can be measured as the number of connections, available SOA services, process space, and hardware. Here’s a good visualization of what I’m talking about:
This application (i.e., website) makes demands on two services. One service is a webserver powered by Apache. The other is an application front-end powered by Tomcat. Each service has its own job to do. In turn, the application components make their demands on each subsequent asset in the chain, all the way down to the network infrastructure.
So instead of thinking of supply simply as available cycles and memory, I think of supply as what’s demanded at each layer. I then reefine supply requirements based on these demands.
In the example below you see a list of the web requests requested by a browser, along with the response time of each request. Viewing this from an inventory standpoint, can I supply the Web requests the customer is requesting? Do I have the right Web requests to deliver? Can I get the requests to the customer in time?
Looking at this example, I better have a lot of instances of /orange.jsf available and I’d better be able to deliver them quickly.
My analogy begins to stretch a little thin at this point. I obvously don’t have a stockroom with a bucket of web requests – Instead I have a program that runs in a container. The program is the code (i.e., inventory) that is executed while the container controls (via logistics) how I get to that inventory. Knowing this, I now need to view my supply through a higher level of metrics:
My code is really made up of requests to other services. Here the evaluation process begins anew: do I have an adequate supply of JourneyService available? What’s most interesting here is CPU time. Remember that the Tomcats were hosted across 4 machines? This means that the supply is robust and scalable. What would happen if we hosted the cluster across 6 or 8 machines?
To answer this question we must finally address the supply = infrastructure part of the conversation. Looking at the processes that support this service, you can see that there is plenty of supply, indicated by low processor utilization.
In each instance, there is plenty of capacity supply, so adding more won’t help. However, clustering on faster boxes will improve speed. Though only marginally because this service demands more of other services than hosts.
Returning to my inventory analogy, having something in stock is of no use if you can’t put your hands on it. That’s what the container does; it manages access to resources.
I’ve talked a lot about the supply of cycles and services, but memory supply is important, too. Assuming that supply is finite, the conversation eventually reverts back to using available supply as wisely as possible. For example, garbage collection is a process that helps manage memory supply. Continuing with the stockroom and inventory analogy, GC is equivalent to wanting to give a customer an answer regarding their request for a product and putting them on hold while you research whether or not you carry the requested product, and if so, where is the product stored. In terms of network performance, this is the negative impact of garbage collection, commonly known as suspension time.
Talking about complex applications and environments using technology-specific jargon can create confusion. Even in this short article, it was an easy walk from simple concepts to complicated metrics. It can be easy to lose sight of the simplicity your goals too, but keep the faith and remember these guidelines:
- View supply in the context of what is being demanded.
- Each supplier in a stack either does its own work or calls on something else to do work. The work it does itself can be considered infrastructure supply.
Infrastructure supply comes in two forms – more and faster. Running out of capacity? Add more. Running slow? Add speed. Just watch out for the cardinal sin of adding more when the application will only benefit from faster.

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In his Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, will explore the ways that Nutanix technologies empower teams to react faster than ever before and connect teams in ways that were either too complex or simply impossible with traditional infrastructures.

Providing the needed data for application development and testing is a huge headache for most organizations. The problems are often the same across companies - speed, quality, cost, and control. Provisioning data can take days or weeks, every time a refresh is required. Using dummy data leads to quality problems. Creating physical copies of large data sets and sending them to distributed teams of developers eats up expensive storage and bandwidth resources. And, all of these copies proliferating the organization can lead to inconsistent masking and exposure of sensitive data. But some organizations are adopting a new method of data management for DevOps that is delivering transformational business outcomes in faster time to market, lower costs, and great control. In his session at DevOps Summit, Brian Reagan, Managing Director of Blackthorne Consulting Group, an Actifio company, revi...

Virtualization over the past years has become a key strategy for IT to acquire multi-tenancy, increase utilization, develop elasticity and improve security. And virtual machines (VMs) are quickly becoming a main vehicle for developing and deploying applications. The introduction of containers seems to be bringing another and perhaps overlapped solution for achieving the same above-mentioned benefits. Are a container and a virtual machine fundamentally the same or different? And how? Is one technically superior to the other? What about performance and security? Does IT need either one, or both?

Keeping pace with advancements in software delivery processes and tooling is taxing even for the most proficient organizations. Point tools, platforms, open source and the increasing adoption of private and public cloud services requires strong engineering rigor - all in the face of developer demands to use the tools of choice. As Agile has settled in as a mainstream practice, now DevOps has emerged as the next wave to improve software delivery speed and output. To make DevOps work, organizations must focus on what is most relevant to deliver value, reduce IT complexity, create more repeatable agile-based processes and leverage increasingly secure and stable, cloud-based infrastructure platforms.

DevOps is a hot topic. It seems that everyone is talking about it. Some have built business models around DevOps-related tools and themes. There are conferences and trade shows dedicated to DevOps-strategies and techniques. Some people have even made their careers around talking about it. In light of all of that, I find it chuckle-worthy that very few people actually know what DevOps is (just follow #devops on Twitter for proof.) I am not going to be one of many trying to create a buzzword-infested definition of DevOps to suit my particular agenda. Instead, I’d like to talk about what DevOps is not. So, without further ado, DevOps …
