Candid Cuts Monthly AWS Bill by 55%

DoiT pairs Flexsave for Compute automation with CRE-led RDS right-sizing and Cloud Analytics to eliminate wasted AWS spend.

Meet Candid

Candid was founded to offer transformative oral health care. Through best-in-class technology and its innovative approach to partnership, Candid aims to make the highest quality care accessible, approachable, and achievable for dental professionals and their patients. The company's flagship product, the CandidPro orthodontic system, is a comprehensive orthodontic solution customized to the needs of general dentists—bringing more clinical predictability, workflow efficiency, and profitability to clear aligner providers of all experience levels.

The Challenge

Candid aimed to eliminate wasted AWS cloud spend and gain confidence to scale while tapping expert guidance for cost optimization. The company needed to optimize AWS storage economics with governance rather than only reduce headline costs. One main cost was the size of its RDS database, where Candid was significantly over-provisioning, diverting budget from roadmap delivery.

The Solution

DoiT provided in-depth analysis of immediate efficiencies and long-term engineering benefits. Candid adopted Flexsave for Compute for automated savings, worked with DoiT CREs to redesign storage solutions and reduce RDS costs, implemented Cloud Analytics for real-time cost monitoring, and used Anomaly Detection to identify cost spikes quickly.

Results

Achieved 16% reduction in overall cloud spend with Flexsave for Compute automation
Cut monthly cloud bill by 55% after comprehensive cost optimization workshops
Reduced RDS costs by 83% through right-sizing database containers
Eliminated storage waste through S3 lifecycle policies and versioning hygiene
Built AI-powered tool with SageMaker to reduce case submission time by 1-5 minutes

As a customer, the fact we have someone we can rely on, who has our back, is very reassuring. With the console, DoiT provides technology that helps us manage costs, and it also provides really helpful customer service.

Automated savings with Flexsave for Compute

Candid wanted to identify savings on its AWS usage. DoiT recommended Flexsave for Compute, which automatically identifies and applies discounted rates to any of Candid's AWS EC2 workloads not already covered by commitments, freeing engineers from manual tracking. Candid's small team no longer has to spend hours each week reconfiguring their compute workloads or monitoring their commitments to make sure it is always getting the best available price.

Redesigning storage solutions with CRE expertise

When Candid began working with DoiT, it used a large RDS database to run the application that dentists use to submit patient cases. This was running up considerable costs for the company. After talking with DoiT's Cloud Reliability Engineers, the Candid team decided to reduce its RDS container size, significantly reducing the spend on its RDS database. The DoiT CREs also helped Candid manage its Amazon S3 storage costs by identifying default settings that were keeping old versions of files unnecessarily.

Building more efficient cloud infrastructure

Candid worked with DoiT to optimize its cloud usage, focusing on removing inefficiencies in its infrastructure. DoiT console enabled the Candid team to explore in depth what was happening across its cloud infrastructure, focus on cost reduction, and identify possible savings across the business. With Cloud Analytics, Candid can now identify rising costs as they happen, as opposed to reviewing them after they've been incurred, helping it to quickly identify savings and take action.

Cutting out cost anomalies

Candid can now identify cost anomalies in its cloud usage, with the help of DoiT console's Anomaly Detection feature. This alerts the Candid team to unexpected cost spikes, allowing them to take fast remedial action to help keep costs under control. The team spotted several cost anomalies during the past year, including an instance that cost $1,000 a day just because something was poorly configured. DoiT was quick to help investigate, pinpoint the problem, and stop the bleeding.

Helping build innovative use cases with AI

When Candid noticed dentists were spending considerable time manually inserting patients' dental images into their system, Candid used Amazon SageMaker to create an AI-powered tool to select the images automatically which has drastically reduced the time required for case submissions. DoiT worked with the Candid team to help develop the proof of concept and adhere to AWS best practices. DoiT also helped Candid to secure R&D credits from AWS, saving the company thousands of dollars on its SageMaker costs.

What they say

DoiT gave us the confidence to move from experimentation to production. They helped us understand the right way to build AI for the real world.

Milad Rezazadeh, CTO

Attribute™'s cost grouping technology took our cost visibility and allocation to a whole new level. Now, our teams are fully accountable for their budgets, significantly improving our cloud efficiency and helping us minimize unnecessary costs.

Eli Zilbershtein, Head of DevOps, Hippo

You can't tag a customer in a multi-tenant environment. Attribute™ finally shows us what each customer costs and what's driving those costs.

Omri Cohen, Director of Engineering, Platform

Attribute™'s data is truly unmatched. No other solution on the market could deliver the precise customer cost and usage profiles we needed in such a complex infrastructure. Within weeks, the data from Attribute™ transformed our understanding of cost structures, influencing key strategic decisions in pricing, renegotiations, and market positioning.

Jonathan Langer, COO, Claroty

Attribute™ simplified tracking customer costs in our multi-tenant environments. Customer cost measurement is now clear and standardized, and finance gets the business context they need. Integration was quick and required no changes.

Kfir Lippmann, CFO, Salt Security

Attribute™ translates complex cloud bills into actionable, business-centric insights that empower our engineering teams to take true ownership of their costs.

Balamurugan Mohandossgandhi, Head of IT and Infrastructure, PropertyGuru

This has let us get a better idea of what our cost of goods sold really is. It's not every day you come across something that delivers value as quickly as yours did for us. I was seeing useful insights inside the POC, and we had only deployed it to a couple of real clusters.

Jason Moore, Principal DevOps Engineer, Accrete AI

Eliminating the need to tag thousands of resources has freed up my team and we've invested our efforts in enhancing our platform significantly.

Ziv Sivan, VP of Engineering

PerfectScale by DoiT has become an important part of how we optimize Kubernetes at scale at OneFootball. It gives our platform team the visibility, automation, resiliency insights, and confidence we need to balance cost efficiency with production readiness, especially as we prepare for major global football moments like the 2026 FIFA World Cup.

Andrea Benfatto, Platform/Cloud Runtime Engineering Manager

Cloudflow's new RDS End of Life alerts have allowed us to be more proactive on keeping our database instances up-to-date. The new solution gives us internal visibility ahead of time so that we can prepare for upgrades, instead of having to upgrade under pressure while incurring extended support costs.

Jon Fairbanks, Site Reliability Engineering Manager

PerfectScale cut 40% off our total EKS spend, and the automations handle what used to take our team 20 hours a month. Now we spend that time on reliability and performance instead of chasing cost metrics.

Caio Cristo, Director of Infrastructure/SRE

What I really like about DoiT's approach is that you're very hands-on and proactive. Satyam would ping me a few times a sprint, letting me know about the most current features, checking in on how things are going. When we are going through a peak time, that proactiveness makes a real difference. Satyam always comes through whenever we need support and helps us leverage the right experts to get us where we need to be.

Chiamaka Ibeme, Engineering Manager, Platform

SELECT has made important cost data readily accessible. I will often pull it up during engineering design reviews so we can quickly evaluate cost impact and projections and factor that into our design decisions.

Douglas Zickuhr, Senior Data Platform Engineer at Personio
