Migration to GCP: from crossing fingers at every deploy to a scalable platform for TenderWolf

TenderWolf, a European SaaS platform for public tender discovery, faced scalability issues due to a manual deployment process that slowed releases and increased operational risk. ACA Group led a cloud migration to Google Cloud Platform (GCP), implementing serverless architecture and automated DevOps pipelines. This solution enabled faster, more reliable deployments without downtime, improved application performance, and reduced infrastructure costs by 50%, providing a scalable and efficient cloud-based platform for continued growth.

Challenge

Manual, error-prone deployments limited release speed, caused stress, and made scaling difficult for a data-intensive SaaS platform.

Solution

Migration to Google Cloud Platform with serverless architecture and automated deployments, ensuring seamless transition without downtime.

Approach

A carefully planned migration with a small, dedicated team, combining deep technical expertise with close, hands-on collaboration.

Result

50% cost reduction, 25% faster performance, smoother DevOps, and a scalable platform enabling faster, stress-free releases.

Every tech scale-up runs into the limits of its application architecture at some point. It’s the moment you realize that small adaptations will no longer suffice.

Cloud Project Manager Roel Van Steenberghe: “At TenderWolf, a new deploy meant a lot of manual steps their developers had to go through. This put a limit on the amount of deploys they could carry out. Meaning it took too long to get new features to their users.

Stress

“But all this manual work also caused stress. Even if their team did everything right, they still had to cross their fingers with every update. And when a problem occurred, it always took a while to troubleshoot. That’s not the situation you want to be in as a developer.”

TenderWolf realized they had to migrate their current set-up. But migrating to a new cloud environment is a big step. Especially at a scale-up, where every team member already has a lot of day-to day-challenges on their plate. Plus, a cloud migration requires specific expertise that is not core to a developer’s job.

On top of that, TenderWolf is running a data-intensive SaaS application. So it was key to maintain a seamless, uninterrupted service for their customers.

Challenges accepted!

Migration plan

Roel: “It always starts with mapping out the initial setup. Together with TenderWolf, we talked through the ins and outs. Then we suggested optimizations for each part.”

“As a next step, we tailor a migration plan, covering even the smallest details. A plan we test out in a staging environment. This way we ensure that the actual migration goes as smoothly as possible.”

“During the migration, it’s our job to keep the balance between going full speed and taking our foot of the gas during those crucial steps.”

Small, dedicated team

“This is where we really made the difference. Scale-ups like TenderWolf work lean and mean. To match that way of working, we did three things.”

We kept the team to the absolute minimum. Two ACA colleagues took care of everything.
We picked out colleagues that combine tech expertise with good communication skills.
We insisted that all meetings took place in person.

“This worked so well. Nothing got lost in translation. Not us versus them. No noise. Instead we had face-to-face meetings that were very hands on, and in which things got done. This was a prime example of working together.”

Together, we enhanced the DevOps experience for the development team, enabling more frequent releases without downtime. This results in a faster product development cycle.

Through careful planning and optimization, we reduced monthly costs by 50% compared to their legacy solution. And while we reduced costs, the application now loads 25% faster than before.

“As their migration partner, we helped TenderWolf make the right decisions. GCP has a lot to offer, but it comes down to picking out the elements that will really benefit your company.”

“We then together made it happen, combining our technical expertise with project management skills and the experience that comes from a multitude of these types of migration projects. With us, TenderWolf had one partner that took care of everything.”

No longer on their own

“I think we also brought peace of mind to their team and their way of working. Before, their developers had to bear final responsibility. But they were on their own and the setup itself was not fully transparent. If there was a problem, they had to figure it out themselves. And with all the manual work, this caused a lot of stress.”

“Now they are sure everything is set up correctly and that everything is mapped out. And if they need our support on something: help is just one Slack message away.
