Poor application performance can be fatal for your enterprise, avoid app degradation with application performance testing

If you’ve ever wondered what can possibly go wrong’ after creating a foolproof app, think again. Democrats’ Iowa Caucus voting app is a case in point. The Iowa caucus post-mortem pointed towards a flawed software development process and insufficient testing.

The enterprise software market revenue is expected to grow with a CAGR of 9.1% leading to a market volume of US$ 326,285.5 m by 2025. It is important that enterprises aggressively work towards getting their application performance testing efforts on track to ensure that all the individual components that go into the making of the app provide superior responses to ensure a better customer experience.

Banking app outages have also been pretty rampant in recent times putting the spotlight on the importance of application performance testing. Customers of Barclays, Santander, and HSBC suffered immensely when their mobile apps suddenly went down. It’s not as if banks worldwide are not digitally equipped. They dedicate at least 2-3 percent of their revenue to information technology along with additional expenses on building a superior IT infrastructure. What they also need is early and continuous performance testing to address and minimize the occurrence of such issues.

It is important that the application performs well not just when it goes live but later too. We give you a quick lowdown on application performance testing to help you gear up to meet modern-day challenges.

Application performance testing objectives

In general, users today, have little or no tolerance for bugs or poor response times. A faulty code can also lead to serious bottlenecks that can eventually lead to slowdown or downtime. Meanwhile, bottlenecks can arise from CPU utilization, disk usage, operating system limitations, or hardware issues.

Enterprises, therefore, need to conduct performance testing regularly to:

  • Ensure the app performs as expected
  • Identify and eliminate bottlenecks through continuous monitoring
  • Identify & eliminate limitations imposed by certain components
  • Identify and act on the causes of poor performance
  • Minimize implementation risks

Application performance testing parameters

Performance testing is based on various parameters that include load, stress, spike, endurance, volume, and scalability. Resilient apps can withstand increasing workloads, high volumes of data, and sudden or repetitive spikes in users and/or transactions.

As such, performance testing ensures that the app is designed keeping peak operations in mind, and all components comprising the app function as a cohesive unit to meet consumer requirements.
No matter how complex the app is, performance testing teams are often required to take the following steps:

  • Setting the performance criteria – Performance benchmarks need to be set and criteria should be identified in order to decide the course of the testing.
  • Adopting a user-centric approach – Every user is different and it is always a good idea to simulate a variety of end-users to imagine diverse scenarios and test for use cases accordingly. You would therefore need to factor in expected usage patterns, the peak times, length of an average session within the application, how many times do users use the application in a day, what is the most commonly used screen for the app, etc.
  • Evaluating the testing environment – It is important to understand the production environment, the tools available for testing, and the hardware, software, and configurations to be used before beginning the testing process. This helps us understand the challenges and plan accordingly.
  • Monitoring for the best user experience – Constant monitoring is an important step in application performance testing. It will give you answers to what, when, and why’ helping you fine-tune the performance of the application. How long does it take for the app to load, how does the latest deployment compare to previous ones, how well does the app perform while backend performances occur, etc. are things you need to assess. It is important that you leverage your performance scripts well with proper correlations, and monitor performance baselines for your database to ensure it can manage fresh data loads without diluting the user experience.
  • Re-engineering and re-testing – The tests can be rerun as required to review and analyze results, and fine-tune again if necessary.

Early Performance Testing

Test early. Why wait for users to complain when you can proactively run tests early in the development lifecycle to check for application readiness and performance? In the current (micro) service-oriented architecture approach, as soon as the component or an interface is built, performance testing at a smaller scale can allow us to uncover issues w.r.t concurrency, response time/latency, SLA, etc. This will allow us to identify bottlenecks early and gain confidence in the product as it is being built.

Performance testing best practices

For the app to perform optimally, you must adopt testing practices that can alleviate performance issues across all stages of the app cycle.

Our top recommendations are as follows:

  • Build a comprehensive performance model – Understand your system’s capacity to be ready for concurrent users, simultaneous requests, response times, system scalability, and user satisfaction. The app load time, for instance, is a critical metric irrespective of the industry you belong to. Mobile app load times can hugely impact consumer choices as highlighted in a study by Akamai which suggested conversion rates reduce by half and bounce rate increases by 6% if a mobile site load time goes up from 1 second to 3. It is therefore important that you factor in the changing needs of customers to build trust, loyalty, and offer a smooth user experience.
  • Update your test suite – The pace of technology is such that new development tools will debut all the time. It is therefore important for application performance testing teams to ensure they sharpen their skills often and are equipped with the latest testing tools and methodologies.

An application may boast of incredible functionality, but without the right application architecture, it won’t impress much. Some of the best brands have suffered heavily due to poor application performance. While Google lost about $2.3 million due to the massive outage that occurred in December 2020, AWS suffered a major outage after Amazon added a small amount of capacity to its Kinesis servers.

So, the next time you decide to put your application performance testing efforts on the back burner, you might as well ask yourself ‘what would be the cost of failure’?

Improve the quality of digital experiences with Performance Engineering

Quality at the heart of business performance

“In 2020, the key expectation is fast, reliable, and trustworthy software.” *

As businesses embrace the Agile/DevOps culture and the emphasis on CI/CD is growing, quality assurance is seen as a standalone task, limited to validating functionalities implemented. When QA and Testing is an afterthought in an Agile/DevOps culture, the result is a subpar consumer experience followed by an adverse impact on the revenue pipeline. Poor customer experience also directly impacts brand credibility and business equity. While UI/UX are the visible elements of the customer experience, product, or service performance is a critical element that is often neglected. Performance Testing identifies the gaps that are addressed through Performance Engineering.

Small steps, significant gains – the journey towards Performance Engineering

The deeper issue lies in the organization’s approach towards quality and testing – it is considered an independent phase rather than looked upon as a collaborative and an integrated approach. Performance engineering is a set of methodologies that identifies potential risks and bottlenecks early on in the development stage of the product and addresses them. It goes without saying that performance is an essential ingredient in the quality of the product, there’s a deeper need for change in thinking – to think proactively, anticipate early in the development cycle, test and deliver a quality experience to the end consumer. An organization that makes gradual changes in its journey towards performance engineering stands to gain significantly. The leadership team, the product management, and the engineering and DevOps at different levels need to take the shift-left approach towards performance engineering.

Make Performance Engineering your strategic priority today

Despite the obvious advantages, performance testing is typically a reactive measure that is addressed after the initial launch. However, organizations need to embrace performance engineering measures right from the design phase, start small, and take incremental steps towards change.

Covid-19 has rapidly changed the way consumers behave globally. Businesses caught onto remote working; consumers moved shopping, entertainment, banking, learning, and medical consultations online. Consider the quantum jump in usage triggered by the pandemic.

The dramatic increase in the use of digital services has covered decades in days.**

Companies that adopted scalability and performance centric design have moved swiftly to capture the market opportunity.

With multiple user-interfaces across sectors being the norm and the increasing complexity of digital experiences, it is critical for businesses to get it right the first time in order to gain and retain customers’ trust.

As cloud migrations continue, whether rehosting the app on an IaaS or rebuilding a new approach, performance engineering ensures that migrated systems withstand sudden surges in usage. According to a Sogeti and Neotys report, 74% of the load testing infrastructure is operated in the cloud today. Cloud infrastructure providers ensure reliability but they may not be aware of the performance metrics that matter to the business and their impact. As organizations move from monolithic systems to distributed architectures provided by an assortment of companies, corporate leaders need to recognize the importance of performance engineering and embrace it to deliver the right solutions for the first time.

Our approach to Performance Engineering philosophy

At Trigent, we put the customer experience at the heart of planning the entire testing cycle. Our performance engineering practices align with ‘metrics that matter’ to businesses in the DevOps framework. While testing identifies the gaps in performance, the onus of architecting it right lies on the DevOps engineering team with proactive inputs from QA and Testing.

Performance engineering is also a way of thinking, the ability to plan for performance at the time of design, right at the beginning. As for quality, besides testing for functionality, anticipating potential bottlenecks helps us assess the process in its entirety in the beginning.

Asking some of these customer-centric questions early on shifts the perspective right at the outset. Ask them early, and you’re on your way to a performance engineering culture.

Parameters that matter

‘Will my application meet the defined response-time requirements of my customers?’

Consider an app that doesn’t respond within the expected standards of the customer; the chances of that application making it to the customer’s phone screen is pretty slim.

‘Will the application handle the expected user load and beyond?’

An application that tested well with 10 users may fail when that number is multiplied by a thousand or two.

We take the viewpoints of multiple stakeholders, consider parameters that matter to the customer, and assess impact early on.

Customer experience matters

Performance Engineering takes into account the overall experience of the end-user and their environment.

Asking pertinent questions such as ‘Will my users experience acceptable response times, even during peak hours?’ or ‘Does the application respond quickly enough for the intended users?’ does well to anticipate potential pitfalls in network usage and latency.

‘Where are the bottlenecks in my multi-user environment?’

Understand the real environment of the user and their challenges to provide a quality user experience.

Early Focus

The non-functional aspects are integrated into the DevOps and an early focus on performance enables us to gain insights into architectural issues.

‘How can we optimize the multi-user application before it goes live?
‘How can we detect errors that only occur under real-load conditions?

Quick course corrections help optimize performance and make the product market-ready. Besides faster deployment, quality assurance gives our clients an added advantage of reduced performance costs.

Architect it right

‘What system capacity is required to handle the expected load?’
‘Will the application handle the number of transactions required by the business?’

Important questions like these focus on architecting the product for performance. As part of the performance engineering methodology, our teams consistently check and validate the capabilities at the time of developing the product or scaling it up. We take the shift-left and shift-right approach to anticipate, identify, and remove bottlenecks early on. Getting the architecture right enables us to deliver and deploy a high-quality product every time.

Performance engineering done right is sure to improve the planning-to-deployment time with high-quality products. Plus, it reduces performance costs arising out of unforeseen issues. A step-by-step approach in testing makes sure organizations move towards achieving performance engineering. Talk to our experts for scalable performance engineering solutions for your business.
