Key Insights from Migrating Tableau to the Cloud

Successful Cloud Migration Strategies for Banks

USEReady’s Guide to Tableau Cloud Migration

Imagine having to move a house from where it sits to another part of the town while remodelling it completely from the inside. You can’t break anything, and you have people staying in it all throughout. That’s what it’s like to migrate a massive on-prem Business Intelligence (BI) setup to cloud. It’s a daunting task fraught with risks and challenges – from data loss to disruptions in critical business operations. 

But that’s exactly what we did for a major U.S. bank. We migrated its on-prem Tableau Server to Cloud while accelerating the entire migration process and optimizing its analytics without disrupting the on-going business operations. This blog is essentially the story of how we achieved this feat.

The Challenge

The bank, a well-known US financial institution was grappling with the limitations of its on-prem Tableau Server environment. Its Tableau Server setup housed years of critical data, supported complex reporting structures and involved thousands of users and groups. With time it struggled to scale up its performance. It missed cutting-edge features offered by modern, cloud-native BI offerings. The bank’s IT team was spending valuable resources on maintaining and managing the infrastructure, diverting attention from more strategic initiatives.

Moreover, the bank had a broader mandate to adopt SaaS solutions, aiming to improve IT operations, optimize costs, enhance scalability, and gain faster access to modern BI features. It was clear that a move to Tableau Cloud was the logical next step, but the migration process presented its own set of challenges.

Enter STORM

This is where STORM, our proprietary Tableau Server to Cloud migration accelerator, came into play. STORM isn’t just another migration tool; it’s a comprehensive, script-based, framework-guided solution designed to streamline and automate key migration processes.

What sets STORM apart is its ability to perform a thorough migration assessment, facilitate content clean-up, and optimize the entire process. These features were crucial in handling the scale and complexity of our client’s environment.

The Migration in Numbers

To put the scale of this migration into perspective, let me break down some key figures: 

  • Over 1,020 data sources migrated, including 600 embedded data sources
  • 1,300 workbooks transferred
  • Configurations for 2,000 users, groups, and permissions seamlessly transitioned 

The data landscape was diverse, integrating sources from Tableau Server, SQL Server, Excel, Amazon Athena, Amazon Redshift, Oracle, and PostgreSQL into the new Tableau Cloud environment. For on-premises data sources that couldn’t directly connect to the cloud, we implemented Tableau Bridge, ensuring uninterrupted data flow. 

The STORM Advantage

The deployment of STORM delivered tangible, measurable benefits:

Time Efficiency

Time Efficiency

We achieved a 50% reduction in migration time compared to traditional methods. In the fast-paced world of finance, this time saving is invaluable.

Automation

Automation

With 60% of the process automated, we significantly reduced manual effort. This not only sped up the migration but also minimized the risk of human error.

Optimization

Optimization

We optimized 30% of the target report count, leading to improved efficiency in the new cloud environment.

Key Learnings

Every migration is a learning experience, and this project reinforced several crucial points for us:

Specialized Tools Matter

Specialized Tools Matter

The success of this migration underscores the importance of using dedicated tools like STORM. Generic solutions often fall short when dealing with the intricacies of BI platform migrations.

Automation is Key

Automation is Key

The high degree of automation not only accelerated the process but also ensured consistency and reduced the risk of errors that often plague manual migrations.

Data Source Diversity

Data Source Diversity

Handling a wide array of data sources requires careful planning and execution. STORM’s versatility in managing various data platforms was crucial to our success.

Configuration Precision

Configuration Precision

Accurate transfer of user permissions and group configurations is often overlooked but is vital for maintaining security and user experience in the new environment.

Looking Ahead

As more organizations recognize the benefits of cloud-based BI solutions, migrations like this will become increasingly common. At USEReady, we’re continually refining STORM to meet evolving needs and challenges in the BI landscape. 

The successful migration for this major U.S. bank serves as a blueprint for other financial institutions and large enterprises looking to make the leap to Tableau Cloud. With the right tools and expertise, what seems like a daunting transition can become a streamlined, efficient process that opens up new possibilities for data-driven decision-making.
