How IronScales Reduced K8s Costs by 21% With Automatic Pod Rightsizing

3 Min read

About The Customer

IronScales is trusted by over 10,000 global organizations to protect their inboxes from Phishing, BEC and QR code attacks. Using a combination of AI and human insights, the company’s platform empowers IT security leaders to spend less than 6 minutes each day on email security. But under pressure to increase economic efficiency, their own 3-person DevOps team was forced to spend dozens of hours each month manually right-size kubernetes resources.

GlobalDots selected a solution that automatically adjusted CPU and Mem requests of Kubernetes pods during runtime – helping them reduce cloud costs and spend less time on manual adjustments each week.

The Problem: Manual Rightsizing to Manage Mini Peaks

The company’s kubernetes pods were routinely over-provisioned. They had strict SLA targets to meet, and without the ability to adapt resources in real-time, this meant they either risked breaching SLAs or used more resources than required.

Moreover, their cloud instances used a static configuration, which made managing sudden peaks in traffic difficult. When the company onboarded a large client or conducted a Proof of Concept (POC), the system would be overloaded, leading to errors and slowness. The DevOps team would have to manually update the resources every time this happened.

…Auto-scaling enabled them to cut compute expenses by 25%

Before we get into how organizations can keep cloud spend at bay, let’s first provide a cloud cost optimization definition. Simply put, cloud cost optimization includes the design and management of cloud architecture as efficiently as possible.

Under pressure to increase economic efficiency, the DevOps and Dev team began manually rightsizing instances and applied horizontal auto-scaling – which enabled them to achieve impressive compute optimization and cut compute expenses by 25%. But these efforts were ultimately a band-aid, not a cure, because they were not scalable or applicable for the long-term.

The DevOps team consisted of just 3 professionals, and the manual approach took up dozens of man-hours each month – and when they undertook an end-of-month analysis, it became clear there was still a lot of waste and Kubernetes inefficiencies.

The Solution: Dynamic and Automated Resources Optimization

Understanding that an automated solution was required, the team followed GlobalDots’ suggestion to solve the problem. Our experts saw that the company needed to simultaneously avoid over-provisioning and meet its SLA targets. The solution our experts selected ensured both could be achieved.

The platform simplifies Kubernetes resource management, dynamically scaling resources to match real-time demand. It continuously adjusts CPU and Mem requests of Kubernetes pods during runtime to not only improve efficiency, but also eliminate out of memory (OOM) and CPU errors. This enabled the DevOps team to optimize their resource usage while spending less time manually rightsizing.

Better still, the solution featured a transparent dashboard to easily analyze cost clusters and set alerts for budget deviation. This empowered the DevOps team to demonstrate the cost savings they were making and proactively manage their spending.

The Results

  1. IronScales cut kubernetes costs by 21% while reducing SLA breaches by 13%.
  2. DevOps and senior developers spent 18% less time manually adjusting the system.
  3. The application’s latency was reduced and performance improved.

With GlobalDots, we’ve seen K8s costs drop by 21%, also SLA breaches decrease in 13% – making our lives much easier. Plus, our DevOps and senior developers are spending 18% less time on tedious manual adjustments.
