Choosing the Right Cloud Data Warehouse

Devon Tackels

Head of Communications, Sigma

Having a centralized cloud data warehouse is crucial for any data-driven company. Cloud data warehouses serve as a central repository for all your organization’s data—providing teams with data access to analyze and report on business performance.

If you’re considering a move to a cloud-based data infrastructure, you’re not alone. It’s estimated that more than 80% of enterprise workloads will run in the cloud by 2020.

But selecting the right cloud data warehouse isn’t an easy decision. It pays to do your homework in advance. The wrong decision will cost you down the line and disrupt operations.

As you explore different vendors, here are the key things to keep in mind when comparing cloud data warehouses.

Key factors to consider


Growing companies should consider investing in a warehouse that can grow with them. This is one of the greatest benefits of the modern cloud data warehouse, but keep in mind that each warehouse scales differently.

When choosing a provider, consider how easy it is to scale, the cost of scaling, and what IT resources you need to grow along the way. Ideally, you would find a solution that can scale automatically to support any level of concurrency or query volume.

Accessing and processing data in the warehouse takes time. But the cloud makes this faster.

Each provider stores and processes queries in slightly different ways. For example, some process data in parallel, while others will spin up as many clusters as needed to deliver results in seconds. You’ll want to learn what limitations exist and whether they will impact the time it takes to generate insights for users.

Unlike on-prem solutions, the leading cloud data warehouse providers are incredibly quick to release the most up-to-date security features and protocols via patches—meaning internal IT teams won’t have to maintain security themselves. Depending on your industry, there may be specific security requirements your data warehouse needs off the shelf. Ensure whichever warehouse vendor you choose meets the requirements before you set up a PoC or sign a contract.

With cloud data warehouse providers, you’re generally only paying for what you use. But there are some stipulations to consider.

Depending on the provider, you may be charged at a flat rate, per hour for storage and compute, or pay-per-use of compute and storage. Consider the cost today and in the future. Choose a pricing structure that works with your needs so it’s easy to predict the costs down the road as you scale.

As your company and data needs grow, you’ll need to onboard additional users and support new data sources. That’s where integrations become essential. Forecasting changes downstream will save you headaches later. Be sure your data warehouse provider integrates with your ETL/ELT and BI tools of choice.


Generally speaking, cloud data warehouses are much more reliable than on-premises data warehouses of the past.

Choosing a provider such as Snowflake, Amazon, Microsoft, or Google means you get world-class engineering teams on your side. That said, it still pays to check out how they have managed past issues and how long they take to reach a resolution. A big part of this is the reputation of customer service teams and the way they communicate. Make sure to choose a vendor that can support your organization if and when something goes wrong.


How you use a data warehouse may ultimately determine the provider you choose. Make sure you consider what your company needs and the use case of teams.

If you’re mostly using your data warehouse for machine learning and data science, your needs will be much different than if you want to provide on-going, ad-hoc analysis or self-service analytics to your entire company. Consider whether you need real-time data access, built-in statistical functions, data preparation, or support for multiple data types.
