[00:00:00] Introduction

Ori Wiseman (Silk):
Welcome everyone to our continuing webinar series on cost and performance. Today’s session is titled “How Silk Delivers 10X Performance at Over 40% Lower Cloud Costs.”

Joining me is David Berliner, Senior Director of Product here at Silk and our resident FinOps and TCO expert.

David Berliner (Silk):
Thanks, Ori — great to be here. My role focuses heavily on helping customers understand total cost of ownership and where Silk creates measurable savings.

Ori:
Perfect. Today we’ll dig into how Silk achieves those cost and performance advantages, particularly for large relational databases in Microsoft Azure — where native options often fall short for enterprise-scale workloads.

[00:02:00] Understanding Cost Inefficiency in Cloud Storage

Ori:
So, David — what makes Silk so different from native Azure storage when it comes to cost efficiency?

David:
It starts at the data layer. With Silk’s thin provisioning, customers pay only for the storage they actually use — not what they provision.

In Azure, if you deploy a 100 TB managed disk but only use 2 TB, you’re still paying for all 100 TB. Silk eliminates that waste.

Across our customer base, we’ve seen an average 33% immediate savings just from thin provisioning.

Ori:
And that’s based on real customer data — not theoretical numbers?

David:
Exactly. These are live results from deployed environments, and for customers new to Silk, the savings are often even greater.

[00:04:00] Data Reduction and Compression

David:
Beyond thin provisioning, Silk applies data reduction, removing extraneous zeros and compressing data. On average, this shrinks data by two-thirds — a major efficiency gain.

Ori:
Does that include deduplication too?

David:
Yes, for some workloads. While deduplication is less impactful for databases, it’s valuable for other data types. The combined effect of compression and thin provisioning significantly lowers total storage costs.

[00:05:00] Independent Scaling of Performance and Capacity

Ori:
Let’s talk about performance.

David:
In Silk, performance and capacity scale independently. Most native cloud services tie IOPS to storage size — so to get more performance, you must buy more capacity.

With Silk, you can scale performance by adding C-nodes without changing storage size. It’s instantaneous, with no downtime and fully automatable via API.

Ori:
That’s powerful — and you can even script scaling around known demand spikes like Black Friday or end-of-month processing.

David:
Exactly. We’ve built full API support for automation and policy-based scaling.

[00:07:00] The VM Performance Gap

Ori:
I looked at Azure’s own VM documentation and found a huge bottleneck — throughput scales only with core count.
For example, to get 1.5 GB/s throughput, you’d need a 64-core VM.

David:
Right — and that’s where costs explode. Cores drive both compute and licensing costs, especially for SQL and Oracle.

Ori:
Here’s the crazy part: we’ve tested Silk running 3 GB/s throughput on a 2-core VM — performance Azure can only match with a 96-core instance. That’s 48x fewer cores for the same result.

David:
Exactly. Customers can run smaller VM shapes with greater performance — that’s where the 40%+ cost savings really compound.

[00:11:00] Customer Example: Healthcare Industry

David:
We’ve seen this proven in the field. One healthcare customer doubled their environment size while reducing overall cost by 26%.

In their data warehouse, they used Silk to switch from an expensive M128ms VM to a D96 — a smaller series with 33% fewer cores — and achieved 76% total VM savings.

Ori:
That’s remarkable — smaller footprint, better performance.

[00:13:00] Extreme VM Comparison

Ori:
There’s a top-end Azure VM — the M176bds_v3 — offering 10 GB/s throughput at $60,000 per month. Compare that to the E192ids_v6, which costs $13K/month and, with Silk, delivers 35 GB/s throughput — more than triple the speed at one-fifth the price.

David:
That’s the definition of better performance at lower cost.

[00:15:00] Copy Data Management and “Echo”

Ori:
Let’s talk about copy data management, one of Silk’s most powerful capabilities.

David:
Most organizations maintain multiple data copies — sometimes 20 or more — for analytics, dev/test, or AI. With Silk’s thin cloning, those copies consume minimal space. You only pay for incremental changes, not full copies.

Ori:
And Silk’s Echo feature takes it further — near-instant copies that are writable, secure, and refreshable in minutes.

David:
Right. One healthcare customer reduced nightly ETL from 14 hours to 15 minutes, and a payer customer cut dev/test refresh time from a week to minutes.

[00:20:00] Business Value and Operational Impact

David:
Our Business Value Assessments (BVAs) capture both hard and soft cost savings.
For instance:

Hospitals using Silk saw real-time access for clinicians by eliminating ETL lag.

Developers gained faster refresh cycles, improving productivity and agility.

Ori:
Those soft gains often translate into millions in avoided downtime and faster time-to-market.

[00:21:00] Preparing for AI and “Agent Chaos”

Ori:
We can’t skip the elephant in the room — AI.

David:
Right. AI workloads, especially agentic systems, create unpredictable database traffic — we call it “Agent Chaos.”

Large language models are non-deterministic — you won’t get the same output every time. That unpredictability can hammer production databases with random spikes.

Ori:
Exactly. Silk isolates production from those risks. With our cloning and performance architecture, customers can safely run AI training or inference on copies — not live systems — with no performance hit.

[00:25:00] The Broader AI and Data Landscape

Ori:
Relational databases still hold the majority of enterprise data — nearly 30% of all global data, representing tens of zettabytes.

As AI scales, those relational workloads will take the brunt of new demand. Silk helps organizations absorb that surge without re-architecting their environments.
