By Mark In recent years, numerous tech organizations have restructured and transformed under the name of DevOps to accelerate software development and improve product quality. While the intention to break down silos between Development and Operations to foster collaboration was ideal, I have frequently witnessed production environments where this concept became distorted, causing significant difficulties. (In fact, it makes me wonder if this flawed state will simply continue to persist in the future.)
Particularly in small-to-medium enterprises (SMEs) or rapidly growing startups, DevOps often degenerates into a structure where “developers shoulder the entire burden of operations”—essentially, ‘Dev + Solo Ops’. A bizarre routine becomes entrenched: coding business logic during the day and pulling on-call shifts at night, constantly disrupted by system failure alerts.
This distorted DevOps structure goes beyond merely overloading developers; it poses fatal risks to overall system stability and business continuity. In this article, we will examine the technical and organizational risks that arise when DevOps degrades into ‘Solo Ops,’ accompanied by concrete real-world examples. Personally, while the prediction that AI advancement will empower individuals while shrinking organization sizes seems accurate, it leaves me thinking, “Is this really how individuals are supposed to scale? This is not a good direction.”

1. Context Switching Overload and Code Quality Degradation
The human brain cannot instantly pivot from complex programming tasks that require deep focus to handling sudden infrastructure failures or operational requests. The first technical risk that arises when the complete integration of development and operations turns into a ‘solo burden’ for an individual lies in extreme context switching. (To be honest, that is exactly why I ended up building tools to mitigate this.)
1.1 Rapid Accumulation of Technical Debt
Under the constant pressure to deploy new features during the day, developers who must simultaneously respond to recurring operational issues (such as server resource depletion, network latency, or infrastructure misconfigurations) cannot invest time in deep architectural design or refactoring. Consequently, ‘stopgap code’ meant only to bypass immediate issues is mass-produced, exponentially increasing technical debt across the entire system.
Real-World Case:
Backend Developer A at an e-commerce startup was in the middle of a massive refactoring project for the payment module. However, during the day, the API servers intermittently went down due to insufficient infrastructure capacity. With no dedicated operations engineer, Developer A had to log into the cloud console himself to manually scale up instances and analyze logs. With his concentration shattered, Developer A rushed to meet the payment module deadline by merely wrapping the old code instead of properly refactoring it. I eventually saw this temporary code turn into a ticking time bomb, triggering a massive payment failure three months later.
1.2 Concurrent Decline in Code Review and QA Quality
Overwhelmed by operational duties, developers lose the time and mental bandwidth required to thoroughly review their peers’ code. This allows latent defects like security vulnerabilities or memory leaks to be deployed directly into production. Most executives believe this issue can be solved using AI—and indeed, it seems to be helping incrementally. However, up to this point, I still frequently see such attempts bounce back either as a massive waste of cost or as a ticking time bomb.
2. Cumulative Fatigue Leading to Human Error and Uptime Reduction
Production systems run 24/7, but human attention spans have clear limits. An environment that demands intense coding during the day and keeps engineers awake at night via PagerDuty alerts inevitably causes chronic developer fatigue.
2.1 Loss of Judgment During Incident Response
When responding to database deadlocks or sudden traffic spikes in the early hours of the morning, an exhausted engineer is highly prone to making critical human errors, such as entering incorrect infrastructure commands or missing the window for a rollback.
Real-World Case:
Developer B, working for a fintech crypto platform, had been on night incident shifts for a week straight. Awakened at 4:00 AM by an alert stating that the database connection pool was full, Developer B opened his terminal in a daze. He was supposed to test terminating (killing) a specific zombie process in the development environment before applying it to production. Due to sheer fatigue, however, he confused the terminals and executed the command directly on the production database’s main process without testing. The system shut down immediately; it took about 4 hours to bring the system back online, and validating the corrupted data took more than two days.
2.2 Uptime Reductions and SLA Violations
When incident recovery relies on a developer’s ad-hoc improvisation rather than standard operating procedures (SOPs) designed by experienced operations specialists (SREs or dedicated Ops), the Mean Time to Resolution (MTTR) increases. This directly translates into a reduction in service uptime, violating Service Level Agreements (SLAs) and destroying business credibility.
3. Absence of Platform Engineering and Infrastructure Fragmentation
Proper DevOps presupposes infrastructure automation and standardization. However, under a ‘Solo Ops’ regime where one or two developers are entirely responsible for operations, there is no room to build sustainable infrastructure.
3.1 Frustration in Adopting Infrastructure as Code (IaC)
While organizations should introduce IaC tools like Terraform or CloudFormation to standardize and version-control their infrastructure, environments consumed by firefighting immediate outages get stuck using ‘ClickOps’—manually creating and modifying resources via the cloud web console.
Real-World Case:
A team developing a logistics management system decided to adopt Terraform to optimize their infrastructure. However, the only person with the practical knowledge to touch the infrastructure was Developer C, the main backend engineer. Flooded with daily mobile app API errors and frontend requests, Developer C could never find the time to write IaC scripts. Ultimately, the clean designs of professional infrastructure architects were completely erased, replaced by an amateurish setup. From Developer C’s perspective, this irony only forced him to spend even more time responding to infrastructure incidents.
3.2 Failure of Configuration Management
As individual developers arbitrarily alter infrastructure settings on the fly, configuration drift occurs, breaking synchronization between the Development, Staging, and Production environments.
4. Loss of Security and Compliance Visibility
When the boundaries between operations and development are blurred indiscriminately, the Principle of Least Privilege—the most critical pillar of system security—is easily compromised.
4.1 Privilege Abuse and Access Control Failures
To ensure rapid incident response, anxious management often makes the short-sighted decision to grant root/admin privileges on production cloud accounts or direct database access to all developers. This sets the stage for major security disasters, including data leaks by insiders, accidental resource deletions, or total infrastructure compromise if a single developer’s credentials are stolen.
Real-World Case:
A telehealth platform shared the production database’s root password with the entire development team. This was done so that individual developers could log in and manually handle data correction requests that poured in day and night. One day, a junior developer connected to the production database—mistaking it for a local test database—and executed a
DROP DATABASEcommand. Although the data was eventually restored via backups, the company underwent a government security audit for violating statutory data access controls and was hit with massive fines.
4.2 Impossibility of Audit Trails
When infrastructure changes are executed directly from individual developer terminals instead of passing through standardized CI/CD pipelines, it becomes impossible to maintain visibility or establish an audit trail to trace exactly how and by whom the infrastructure was altered when a security incident occurs.
5. Attrition of Core Developers and Bus Factor Risks
One of the most dangerous risks a tech organization can face is the concentration of system knowledge within a specific individual. A solo operations structure maximizes this systemic risk.
5.1 Low Morale and Burnout
Engineers who want to grow their careers as developers experience a sharp decline in job satisfaction and suffer severe burnout due to excessive operational and on-call duties. Consequently, the most talented senior developers are the first to leave the organization.
Real-World Case:
Developer D, who played a pivotal role as an architect at a mobile game company, single-handedly performed 24-hour infrastructure monitoring and emergency patching on top of his core duty of optimizing the game engine. Plagued by non-stop incident pages even during national holidays, Developer D experienced extreme burnout and eventually resigned. Once he left, no one remaining in the organization understood or could manage the core architecture, which caused a business-critical delay of over six months for their next project launch.
5.2 Drop in the Bus Factor
If only a single ‘developer-turned-operator’ understands the infrastructure architecture and deployment pipelines of a specific system, his departure leaves the remaining team completely helpless, unable to resolve even minor system glitches.
Conclusion: Transitioning to True DevOps and Platform Engineering
Having developers participate in operations to understand how a system behaves in production is highly positive. However, this should never be used as an excuse to dump the entire burden of operations onto developers simply to cut down organizational costs.
To allow developers to focus on writing code, organizations must implement Platform Engineering—delivering infrastructure as a product—or explicitly define and separate the role of Site Reliability Engineering (SRE) to focus professionally on automation and stability. Ensuring an environment where developers can get a good night’s sleep and immerse themselves in writing high-quality code during the day is the only sustainable way to maintain a safe, robust, and resilient system in the long run.
