PerfectScale for Spot

Save more with Spot Instances–safely and automatically

Maximize savings on EC2 workloads by automatically scaling with Perfectscale for Spot – without sacrificing reliability, uptime or creating manual effort.

Overview

PerfectScale for Spot helps you reduce EC2 costs by automatically optimizing the instance configuration of your AWS Auto Scaling Groups (ASGs). It uses intelligent recommendations to adjust the mix of Spot and On-Demand instances—so you can save more without compromising reliability, application uptime or causing manual effort.

PerfectScale for Spot is built for hands-off optimization. Once enabled, it continuously monitors and updates your ASGs based on availability, pricing signals, and best practices—ensuring you always operate at the optimal balance of cost and resilience.

Pricing

Tag-based automation

Apply a tag to your ASGs to activate PerfectScale for Spot—no manual setup or agent needed

Built-in safeguards

Automatically fall back to On-Demand instances when Spot capacity runs out, ensuring workloads stay available and reliability is never compromised

Real-time configuration engine

Dynamically adjust instance types, purchase options, and availability zones based on changing conditions—so your applications scale without any downtime

Continuous optimization

Keep your infrastructure tuned without ongoing effort or oversight

Built for reliability,
optimized for savings

Traditional cost-saving methods for EC2 Spot Instances are either too risky or too manual. PerfectScale for Spot automates the hard part: managing instance mix, maintaining reliability, and reacting to market conditions in real time—so your teams don’t have to.

Continuous optimization, not static advice

PerfectScale for Spot goes beyond point-in-time recommendations. Once enabled, it automatically updates your ASGs based on pricing, availability, and best practices—no recurring reviews or manual intervention needed.

Built-in risk mitigation with fallback to On-Demand

PerfectScale for Spot ensures application continuity by default. If Spot capacity isn’t available, your workloads seamlessly fall back to On-Demand—so you never have to choose between cost savings and uptime.

Native integration with your existing ASGs

No agents or major reconfigurations required. Just tag your ASGs and PerfectScale for Spot takes over, making it easy to deploy and scale across your environment.

Spot savings are hard to
unlock without risk

AWS Spot Instances offer deep savings but are notoriously difficult to use reliably. Without automation, teams face availability gaps, scaling failures, and lost time managing configurations—making Spot more trouble than it’s worth.

Spot configuration is complex and time-consuming
Learn more

Launch templates, instance types, and mixed instance policies all need to be configured just right. Most teams don’t have the time or confidence to manage it manually at scale.

Availability gaps
can break reliability
Learn more

Spot capacity fluctuates. If your ASGs can’t respond in time, workloads can crash or stall. Manual fallback solutions are slow, brittle, and hard to test.

Manual scaling doesn’t keep up with real-time changes
Learn more

Spot pricing and availability change constantly. Without automation, teams must continuously tune configurations—burning cycles on maintenance instead of innovation.

Chasing stability
can cost you savings

Most teams eventually fall back to On-Demand to avoid the risk of application disruptions. Prioritizing stability without automation or safeguards means leaving the majority of Spot savings on the table—despite best intentions.

“We struggled to leverage Spot effectively, and researching other instances we could run was time consuming. Now we use PerfectScale for Spot for running our batch processing on dynamically scaled Spot Instances, and have saved between 50% – 60% compared to on-demand.”

Mike McFarland, Lead Software Engineer, CattleEye

“As HackerRank’s user base grew, we faced challenges with our AWS infrastructure that resulted in additional expense and frustrating downtime. DoiT’s consulting and cost optimization technology was invaluable, quickly identifying the root causes and providing a multi-step approach to reduce our downtime, decrease EC2 expenses by 24% and cut our on-demand EC2 spend of their non-production ASGs by nearly 50%.”

Vinay Aggarwal, Senior Software Engineer, HackerRank

"Using DoiT to migrate to AWS has prepared us for the future. With the benefits of scalability, flexibility, and improved performance, combined with an optimized cost structure, it’s clear we made the right choice."
