Agile Infrastructure: Scaling More Efficiently

Why Scale-Out (and Scale-Up) Matter More Than Ever

Companies today are being asked to do more with data than ever before. Bigger AI models, faster insights, and workloads that don’t stay in one place, it’s a lot to keep up with. Traditional infrastructure just isn’t built for this kind of speed and flexibility.

The answer isn’t about throwing more hardware at the problem. It’s about building smarter, more agile infrastructure that adapts as demands change. And that’s where scale-out and increasingly, a blend of scale-out and scale-up come into play.

Scale-Out vs. Scale-Up — And Where OSS Fits

When people talk about scale-out, they usually mean adding more nodes or servers and running them in parallel. It’s the model the cloud made mainstream modular, cost-effective, and great for distributed workloads.

Scale-up, on the other hand, is about making a single system stronger by adding GPUs, storage, or memory. That’s often the right answer at the edge, where you don’t have the luxury of endless racks but still need serious compute power.

Here’s the thing: most customers don’t live fully in one world or the other. They need both. And that’s exactly where Agile Infrastructure comes in. Agile infrastructure lets you pool resources: GPUs, storage, accelerators and assign them where they’re needed most. That means you can scale up inside a single box, or scale out across multiple systems, sometimes even both at once.

Think about it this way:

• One expansion system connected to a server? That’s scale-up.
• Two servers sharing a single expansion chassis? That’s scale-up by scale-out in small increments.
• A cluster of disaggregated GPUs pooled across racks? That’s scale-out at datacenter scale.

This hybrid flexibility is where OSS shines.

Why This Approach Matters Now

AI Isn’t Slowing Down
AI workloads are getting bigger and more complex by the day. Training giant models or running real-time inference at the edge takes GPU-dense systems with serious bandwidth and low latency. No single system can shoulder it all anymore. Scale-out paired with agile infrastructure and dynamic orchestration gives you a way to grow capacity without ripping and replacing your infrastructure.

Data Growth Is Relentless
Sensors, platforms, and applications are generating mountains of data. Centralized systems can’t keep up. Agile Infrastructure lets you expand as you go, scaling up individual systems when needed or scaling out clusters when workloads demand it.

Flexibility Beats Overbuilding
The old way of buying oversized systems upfront in the name of “future-proofing” leaves you with idle resources and wasted budget. Agile, modular infrastructure changes that. You add exactly what you need when you need it, whether that’s GPUs for training or NVMe storage for streaming workloads.

Smarter Economics
Scaling in line with demand lowers capex and improves ROI. Even better, Agile infrastructure makes sure GPUs, and other accelerators don’t sit idle, they’re always allocated where they’ll do the most good.

Not Just for Hyperscalers
Cloud giants might have pioneered scale-out, but the need is everywhere now. Defense, healthcare, autonomous systems, industrial automation all of them need dense compute they can control, customize, and sometimes deploy in rugged, mobile environments.

That’s why OSS builds systems that deliver datacenter-grade performance wherever you need it from racks in enterprise datacenters to mobile command centers at the tactical edge.

Speaking the Language of Modern Infrastructure

The way the industry talks about infrastructure is changing too. It’s not just “scale-up” and “scale-out” anymore.

• Dynamic Orchestration speaks to software that manages and coordinates resources automatically.
• Intent-Based Orchestration takes it further infrastructure that interprets your goals and provisions resources with minimal human touch.
• And at the core, Agile Infrastructure ties it all together, making it possible to scale both ways depending on the workload.

Final Take

If you’re relying on just vertical scaling, you’re already behind. If you’re only focused on horizontal scaling, you’re still leaving flexibility on the table.

The future is hybrid scaling, the ability to scale up and scale out as needed, powered by agile infrastructure and guided by dynamic orchestration.

And that’s exactly where OSS sits. Whether it’s training next-gen AI in a datacenter or running rugged systems at the edge, we help our customers scale smarter, faster, and without limits.
