Finlex cuts cloud costs 50% and ships production AI with DoiT
- Over 65%
- reduction in cloud infrastructure costs from 2024 - present
- 40%
- cost savings achieved through improved visibility and efficient AI architecture
The Challenge
Discount Bank needed to gain Bank of Israel consent to operate PayBox workloads in the cloud while meeting strict banking security requirements. The acquired startup app needed enterprise-grade security features without losing its agility and innovation capabilities.
The Solution
Working with DoiT International, Discount Bank implemented two-step authentication, SSL certification, and database encryption using Key Management Service with Google Kubernetes Engine. They used Compute Engine for regulatory snapshots, BigQuery for transaction monitoring, and GKE for continuous deployment and automatic scaling.
Results
- Gained Bank of Israel approval to operate PayBox in the cloud
- Grew user base from 120,000 to over 1.5 million users
- Achieved 4.8 out of 5 rating on Google Play
- Successfully handles 200% traffic spikes during peak periods
- Deployed new code daily with continuous deployment model
We use BigQuery to monitor all our operations. That means handling large volumes of data, as each transaction generates hundreds of log lines. We've been amazed at how fast BigQuery can generate reports: it's a truly great product.

Meeting Banking Security Requirements
Making sure an application is robust and secure is key for any enterprise, but especially when large numbers of transactions are involved. Working with DoiT International, the PayBox team implemented two-step authentication for logins, SSL certification, and database encryption for sensitive data using Key Management Service with Google Kubernetes Engine. These features bring PayBox in line with the broader Discount Bank security ecosystem. The persistent disk snapshot function on Compute Engine helps meet regulatory requirements by creating snapshots of all transactions every 15 minutes and keeping records for seven years.
Achieving Easy Deployment and Scaling
To keep its application up-to-date, PayBox uses a continuous deployment model on GKE, so new code is deployed every day. As its infrastructure deploys multiple pods in parallel, it is easy to isolate any issues that might occur. GKE scales automatically to meet the peaks in demand that PayBox experiences. Traffic varies over the week, since nights and weekends are much quieter, and seasonal peaks occur around holidays and the beginning of the academic year. A peak might mean 200% more traffic, but with GKE, they can easily handle the extra traffic.
Monitoring with BigQuery
PayBox uses BigQuery to monitor the service it provides by analyzing log data. This means handling large volumes of data, as each transaction generates hundreds of log lines. The team has been amazed at how fast BigQuery can generate reports from this massive dataset. To keep important documentation and information in one place, the PayBox team uses G Suite services including Gmail and Drive to share PayBox-related documents.
Growing Through Partnerships
Since acquiring PayBox's operations in Israel, Discount Bank has successfully gained permission to run PayBox as part of the bank and grown its user base significantly from 120,000 to more than 1.5 million users. User satisfaction with the PayBox app is high, with a rating of 4.8 out of 5 for the Android App on Google Play. The bank is now extending functionality through partnerships with major enterprises, including enabling users to top up their Rav-Kav electronic transport cards through the app.

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
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
I love clicking through SELECT to understand how our environment and workloads are evolving. I probably check it every day. It's coffee and SELECT for me every morning.
Ian Fahey, Senior Analytics Engineer at Loop
You guys have the best UI experience that I've had of any software. It's like you just read my mind where, like, oh, I wish I could click there. Oh, I can
Diana Koshy, Sr. Director of Data Engineering at Kargo
SELECT feels like exactly what Paul and I would have built if we had locked ourselves in a room for 18 months to create our ideal monitoring solution.
Devin McGee, Data Engineering Lead at Home Chef
SELECT dramatically lowers the cognitive load to understanding Snowflake costs. I'm able to sit there and easily understand what's driving the cost. Not to blow smoke up your ass, but it's just so easy to do in your platform
Blake Baggett, Head of Data Operations at Entain
One of the most helpful cost rituals we've setup from SELECT is the weekly spend digest sent to Slack. I can start high level and ensure things are in check. If not, I can very quickly drill down into specific workloads which may have driven the cost spike and remediate them before they become a bigger issue.
Michael Revelo, Manager of data and analytics engineering at ClickUp
Through SELECT's automated savings feature and deep cost visibility, we were able to instantly lower our Snowflake spend by over 40% and achieve a 20X ROI on our SELECT investment.
Skyler Chi, SVP, GTM Productivity & Excellence at Exiger
Our costs had jumped up 3X as we scaled, so we're talking about 60% savings in Snowflake spend after adopting SELECT.
