In 2013, APMdigest published a list called 15 Top Factors That Impact Application Performance. Even today, this is one of the most popular pieces of content on the site. And for good reason – the whole concept of Application Performance Management (APM) starts with identifying the factors that impact application performance, and then doing something about it. However, in the fast moving world of IT, many aspects of application performance have changed in the 3 years since the list was published. And many new experts have come on the scene. So APMdigest is updating the list for 2016, and you will be surprised how much it has changed.
Part 4 of this list covers the application itself.
20. APP COMPLEXITY
The top factor that impacts application performance today is application complexity. Modern day applications are spidery, with thousand of possible optimization points. It's a huge amount of complexity to deal with. It becomes very hard to predict performance ahead of time, and to understand the implications of a software change. Companies need to have real data derived from real-life test scenarios, and need to measure true end-to-end key performance indicators (KPIs) affecting the user experience.

21. APP DESIGN
The top factor that impacts application performance is the architecture of the application itself. Often times you see this when an application is moved or migrated to another environment. For example, the impact of a "chatty" application can be hidden or mitigated on a high speed local LAN, but once moved to the cloud, the slower telecom speeds expose this design flaw in the form of high latency.

Application design/architecture/complexity is the top factor that impacts application performance. It can be quite difficult to mitigate the effects of poor design, even with a great deal of additional work. Poorly designed applications may suffer from poor performance even with relatively low traffic.

Developing apps while looking only from a functionality perspective is one of the most fundamental mistakes in developing applications. You should design your application also from a performance perspective if you want to make sure you deliver a good application. Do this right from the start of the project and you will deliver a much better application. Ignoring this and trying to optimize the performance afterwards is very expensive and doesn't deliver the correct results.

Application architecture – which is part science and part art. There are definitely MANY factors we see impact performance, everything from infrastructure to poor coding to a badly designed database. But fixing these implementation aspects of a poorly architected application can be like chasing your tail, and bad design decisions can haunt you for the life of the application. Applications are complex, often comprised of shared services and deployed on shared infrastructure. The science is in understanding the relationships and interactions between the various components, and the art is in doing so without sacrificing user experience.

22. APP DESIGN: NEW FEATURES
Applications that perform well have to be built effectively and tested meticulously. As such, the biggest impact on application performance is new features. As developers introduce new code, overall performance is affected. Due to schedule pressures, there is often no time remaining to optimize performance. Balancing the demands of time to market and application performance is a requirement for all members of the development, ops, and executive teams.

23. APP DESIGN: LATENCY
Ignoring latency in application design: Chatty applications that require significant communication or synchronization with other components over a network need to be designed with WAN latency in mind. Multi-step communication over the network may work fine in a low-latency LAN environment, but it can become a critical time bottleneck over a higher-latency WAN or over the Internet. Add cloud services with worldwide distribution to this mix, and you have a recipe for disaster.

24. APP DESIGN: IO PATH
The top factor affecting distributed/clustered applications performance is the inability to secure an entire application IO path from compute to storage – leading to unpredicted performance and incapability to guaranty SLA. This often also results in a poor man's solution – underutilized servers reflected in siloed applications' resources to guarantee availability, usually in a multi-tenant environment. Containers reflect the next generation virtualization solution designed to take on significant chunk of the challenge. By taking a holistic application centric approach, IO path from compute to storage resource availability can be guaranteed amongst other entire application lifecycle ops.
VP of Products, Robin Systems
25. APP DESIGN: BUGS
There are many different types of software bugs, all of which can impact software performance. For C/C++ programmers, common bugs include execution state corruption, data structure corruption, race conditions, deadlocks and memory leaks. These bugs can appear regularly in software development. However, they can also appear intermittently, thus unintentionally getting into shipped products. These types of bugs cause the biggest headaches for software vendors, who have to attempt to reproduce an issue their customer is experiencing but often without the issue appearing on the vendor's test systems. In each case, programmers are unaware of, or misunderstood, their contract with the rest of the system. Fundamentally, even in well-developed software, bugs occur because people don't understand what their software really does.
26. APP DESIGN: SECURITY
I think application performance is a huge subject but with what the world of software is going through today a lot has to do with security. I believe that the ability to deliver applications which have been developed with security in mind from the start will have a significant impact on the final delivery. An application which is developed with security in mind has less chance to expose user's personal data and therefore less chance of being taken down by the vendor. High programing quality is not only the speed but also the quality of the code and quality includes secure code.

In the course of researching, documenting and advising on user experience management needs and directions for more than a decade, I've found myself waging a quiet (and sometimes not so quiet) war with several industry assumptions. Chief among these is the notion that user experience management (UEM) is purely a subset of application performance management (APM). This APM-centricity misses some of UEM's most critical value points, and in a basic sense fails to recognize what UEM is truly about ...
We now live in the kind of connected world where established businesses that are not evolving digitally are in jeopardy of becoming extinct. New research shows companies are preparing to make digital transformation a priority in the near future. However most of them have a long way to go before achieving any kind of mastery over the multiple disciples required to effectively innovate ...

This is the third in a series of three blogs directed at recent EMA research on the digital war room. In this blog, we'll look at three areas that have emerged in a spotlight in and of themselves — as signs of changing times — let alone as they may impact digital war room decision making. They are the growing focus on development and agile/DevOps; the impacts of cloud; and the growing need for security and operations (SecOps) to team more effectively ...
As we've seen, hardware is at the root of a large proportion of data center outages, and the costs and consequences are often exacerbated when VMs are affected. The best answer, therefore, is for IT pros to get back to basics ...
Risk is relative. The Peltzman Effect describes how humans change behavior when risk factors are reduced. They often act more recklessly and drive risk right back up. The phenomenon is recognized by many economists, its effects have been studied in the field of medicine, and I'd argue it is at the root of an interesting trend in IT — namely the increasing cost of downtime despite our more reliable virtualized environments ...
