Demystifying serverless in the modern data and AI landscape

Monday June 2, 2025. 11:00 AM , from InfoWorld
Serverless computing has proliferated across cloud platforms, yet its core principles are widely misunderstood and misused. Much of the industry treats serverless as being synonymous with infrastructure abstraction or automation, but this is a limited view that prevents organizations from getting the full benefits of what this architecture can offer.

It’s time to clarify misperceptions and examine what serverless really looks like, especially in a world increasingly shaped by AI and the need for rapid innovation and scaling.

The buzzword problem

When AWS launched Lambda in 2014, it introduced a radical concept: Run code without thinking about servers. Fast forward to today and serverless has morphed into a vague marketing term whose technical meaning has been lost. This matters because it leads to poor implementation choices, inefficient resource allocation, and higher costs.

Three big misconceptions are driving the confusion over serverless:

Auto-scaling compute makes something serverless. Elastic clusters that scale up and down are a step in the right direction, but true serverless means no infrastructure management at all. If servers still need to be configured, it’s not truly serverless.

Multi-cluster warehouses can be called serverless. Some data platforms describe themselves as serverless while still requiring administrators to manage clusters, albeit with some automation. This creates a false expectation of simplicity while merely shifting complexity onto the developer.

Some complexity is inevitable. When cloud services require extensive configuration and optimization, or have opaque pricing models, they’re missing the point of serverless. This complexity should be shouldered by the provider, not the user.

The real meaning of serverless

Serverless architectures adhere to three core principles that are non-negotiable:

True separation of compute and storage. This fully decouples resource requirements, allowing compute capacity to flex without storage constraints, and vice versa. At the implementation level, this means storage access patterns don’t create compute bottlenecks, and compute-intensive operations don’t impact data persistence or retrieval latency.

No provisioning, tuning, or capacity planning. If you have to think about resource allocation, it’s not serverless. A serverless architecture eliminates not just the initial provisioning but the entire life cycle management, including upgrade paths, version compatibility, and regional deployment strategies. This allows development teams to deploy without considering details like instance types, network configuration, or service mesh topologies.

Elasticity is the default, not a feature. True serverless ensures that resources scale instantly and automatically to meet demand, then scale to zero when not needed. This requires advanced resource prediction algorithms, instant instantiation, and stateless execution contexts that can be created and destroyed without operational overhead or performance impact.

The developer experience 

Real serverless platforms eliminate what amounts to a complexity tax for developers—the countless hours spent tuning clusters, managing scaling, and troubleshooting performance. This tax isn’t just measured in time; it’s a persistent drain on highly skilled technical resources.

Serverless architectures should eliminate devops overhead from application development. They accelerate deployment by removing provisioning and scaling decisions. They simplify testing by maintaining consistent behavior across development and production. And they reduce cognitive load by decreasing the number of systems a developer has to understand.

Why this matters in the age of AI

The confusion around serverless is even more consequential with the rise of AI workloads, which are dynamic, compute-intensive, and unpredictable—precisely the conditions where serverless delivers maximum value. 

Organizations building AI applications with a pseudo-serverless infrastructure will frequently run into unexpected costs, limitations of scale, and performance bottlenecks that undermine the competitive advantages and ROI that AI can offer.

What to look for in a serverless platform

If you’re evaluating serverless platforms, here are some characteristics to look for:

Native elasticity that scales instantly from zero to whatever your workload requires, without pre-provisioning or warm-up times.

A transparent cost model that’s directly tied to consumption, without hidden capacity charges or opaque pricing tiers.

Zero operational burden, meaning no clusters, no scaling policies, and no resource planning.

Seamless support for modern AI and data architectures that accommodates unpredictable workloads without performance penalties.

Engineering for true serverless architecture

The core value proposition of serverless isn’t incremental automation; it’s the elimination of infrastructure management as a concern. Organizations must recognize the fundamental principles that actually define serverless: complete separation of storage and compute, zero configuration overhead, and simple consumption-based economics.

The technology for serverless architectures is proven and ready. What’s needed now is architectural clarity and disciplined implementation to fully realize its benefits at scale. By removing the operational weight of infrastructure management, engineering teams can focus entirely on extracting value from data. And in a world defined by speed and intelligence, competitive advantage depends on getting serverless right.

Serverless compute for modern data applications

So, what’s next in the evolution of serverless compute? Today’s data and AI applications are dynamic and unpredictable. They demand a platform that adapts in real time, without tuning, provisioning, or workload isolation. That’s why the next evolution of serverless compute won’t just be about faster scaling or reducing manual overhead. It will be about making compute so seamless, so intelligent, that teams don’t need to think about it at all. It will be about removing infrastructure decisions from the equation entirely.

There will be no need to think about compute sizes, cluster configurations, or separating compute for different workloads. With intelligent resource utilization built in, modern data platforms will automatically adapt to support a wide variety of heterogeneous workloads without the overhead traditionally needed for optimization or intervention. This is how infrastructure finally gets out of the way, allowing businesses to spend less time managing infrastructure and more time delivering value through data systems that are as agile and responsive as the businesses they power.
