In February, what should have been a stress-free payday turned into chaos for many banking app users. Millions found themselves locked out of their online accounts, unable to access their hard-earned money due to widespread app crashes. The frustration and panic were palpable as bills went unpaid and financial plans were derailed.
The incident highlighted a larger issue at play – the growing reliance on mobile banking platforms that are not always reliable or trustworthy. According to recent studies, only 23% of Brits fully trust finance apps, making any disruption in service a major setback in building customer confidence.
To understand why these meltdowns occur and how they can be prevented in the future, we turn to Laurie Maclachlan, VP and MD of EMEA at LaunchDarkly. Laurie sheds light on the underlying problem – outdated legacy systems struggling to cope with the demands of modern banking practices.
### Legacy Systems Under Pressure
Laurie explains that traditional banking systems are under immense strain as operations transition from brick-and-mortar branches to digital platforms. These legacy systems must now seamlessly integrate with third-party services, support various devices and software versions, and maintain connectivity across cloud services, APIs, and mobile interfaces. The complexity of this web of dependencies significantly raises the risk of system failures during peak usage periods like payday.

“Without a structured approach to change… even minor updates can trigger outages.”

### Embracing DevOps for Stability
To mitigate such risks and safeguard customer experiences, banks are urged to adopt a DevOps approach that prioritizes system stability above all else.
#### Progressive Rollouts
One key strategy is implementing progressive rollouts when introducing new features or updates. Rather than deploying changes universally at once – which could lead to catastrophic failures if something goes wrong – banks can gradually introduce updates starting with a small user segment before expanding cautiously.

“By gradually introducing changes… banks can check performance and detect potential issues before they impact the entire customer base.”
#### Automated Monitoring and Instant Rollbacks
Automated monitoring tools play a crucial role in maintaining app reliability by tracking performance metrics in real-time. These tools provide immediate alerts if anomalies are detected, allowing for swift rollbacks to previous stable versions within milliseconds if necessary.

“You can’t fix what you can’t see… automated monitoring ensures timely responses to issues.”
#### Real-Time Adjustments without Downtime
With runtime configuration management capabilities, developers can make on-the-fly adjustments without disrupting overall application functionality. This flexibility enables banks to address issues promptly without taking their entire platform offline.

“Flexibility is crucial for maintaining uptime… real-time adjustments ensure seamless customer experiences.”
#### Targeted Segmentation for Personalized Experiences
Recognizing that one-size-fits-all solutions don’t work in banking, institutions are encouraged to segment users based on unique attributes like device preferences or network environments. This tailored approach allows for customized updates that optimize user experiences while mitigating risks efficiently.

“Segmenting users allows banks… enhance security without disrupting operations.”
### Securing Future Banking Experiences
As digital banking continues its upward trajectory globally with more consumers relying on mobile apps daily, ensuring uninterrupted service becomes paramount for financial institutions worldwide. By embracing best practices like progressive rollouts, automated monitoring, runtime configuration management, and targeted segmentation through DevOps principles,
banks stand better equipped against unplanned disruptions during critical events like payday.
In conclusion…
Through strategic adoption of DevOps methodologies focused on stability enhancement rather than rapid feature release cycles alone,
banks pave the way for reliable applications that foster lasting trust among customers.
