While it wasn't an entirely new concept — the term was coined in the 1990s — Big Data didn't really emerge in the mainstream until 2005. Remember all the hype? Today we know it wasn't just hype — the industry has lived up to the claims and transformed into the underlying force that drives businesses forward. Over the years, the sheer amount of data generated every second has grown exponentially. If this big data is to be analyzed, there has to be a place to store it.
This need for storage led to enterprise cloud data warehouse technology that’s highly efficient in storing and analyzing big data workloads.
Data warehouses are now critical to efficiently utilizing data to derive deep insights. So now the big question is, which data warehouse is best for my business? There are three data warehouse giants that you need to consider: Amazon Redshift, Google BigQuery, and Snowflake.
Here at Integrate.io, our dog's not in this fight. Integrate.io supports all three data warehouses with a no-code ETL solution with blazing fast CDC and reverse ETL capability so our clients can build powerful data integration pipelines into any cloud data warehouse of their choice. However, we want to make sure that our clients who are comparing Redshift vs Snowflake make the right choice.
If we take a look at the powerful relational DBMS database models, Redshift and Snowflake, there are more similarities than differences — but these differences are quite significant.

Redshift vs Snowflake: What is Redshift?
Redshift is a fully managed, cloud-ready petabyte-scale data warehouse service that can seamlessly integrate with business intelligence (BI) tools. So, all you have to do is Extract, Transform, and Load (ETL) into the warehouse to start making smarter business decisions.
Amazon makes it quite easy for you to start out with a few hundred gigabytes of data and scale up or down seamlessly, based on immediate demands. This allows businesses to leverage their data to acquire valuable business insights about themselves or their customers.
To launch your cloud data warehouse, you have to launch a set of nodes known as a Redshift cluster. Each node in the cluster is then partitioned into “slices.” Each slice is allocated a portion of the node’s memory and disk space. This helps balance the workload assigned to the node, which optimizes query performance. Once you have provisioned the cluster, you can upload data sets and run data analysis queries.
Regardless of the size of your data set, you can take advantage of fast query performance by using the same SQL-based tools and BI applications.
Amazon Redshift exhibits superior performance by taking advantage of internal networking components. By utilizing high-bandwidth connections, proximity, and custom communication protocols, the system achieves high-speed communication between nodes.
Redshift vs Snowflake: What is Snowflake?
Like Redshift, Snowflake is also a powerful relational database management system. It’s offered as an analytic data warehouse for both structured and semi-structured data that follows a Software-as-a-Service (SaaS) model.
This means it’s not built on top of an existing database or a big data software platform (like Hadoop). Instead, Snowflake uses an SQL database engine with unique architecture that was specifically designed for the cloud.
Snowflake’s architecture has the unique feature of being a hybrid of traditional shared-disk and shared-nothing models. With a shared disk, the system uses a central data store to which each compute node has access. With shared-nothing, each node in the cluster stores a portion of the entire data set locally.
Snowflake is also a three-layer system that consists of:
- Database Storage: Snowflake manages how the information, like file size, structure, and metadata, is stored in the database.
- Query Processing: Snowflake processes queries using what's known as “virtual warehouses.” Each warehouse represents a cluster node that's independent of other cluster nodes and doesn't share compute resources across virtual warehouses.
- Cloud Services: This layer represents the services that tie together the different components of the system, such as authentication, infrastructure management, query parsing, and access control.
This data and analytics solution is also fast, user-friendly, and offers more flexibility than other, more traditional data warehouses because Snowflake separates compute and storage functions in their pricing, meaning you can pay for only the features you need when you need them. You're never charged for what you haven't used. With this approach, you save money, but you always have the flexibility to scale as needed.
If you've used both Redshift ETL and Snowflake ETL, you already know there’s an abundance of similarities between the two solutions. However, there are additional unique capabilities and other functionalities that come with each platform in relation to security and performance.
For instance, if you’re thinking about running your data analytics workload entirely on the cloud, for example, the similarities between these two robust cloud data warehousing solutions are far greater than their differences.
Snowflake offers cloud-based data storage and analytics in the form of the Snowflake Elastic Data Warehouse. In this scenario, users can analyze and store data using cloud-based hardware and software.
If you use Snowflake ETL, once the data is stored in Amazon S3, for instance, you have the public cloud ecosystem at your disposal. And you can leverage its power without using tech services like Hadoop.
Both cloud warehouse systems are powerful and offer some unique features for data management, but it's important to understand the key differences between Redshift vs Snowflake. Choosing the right solution means comparing integrations, database features, maintenance requirements, security provisions, and, of course, cost.

Redshift vs Snowflake: In-Depth Comparison
Comparing Redshift vs Snowflake shows how these data warehousing solutions and their applications can work depending on your organization's specific requirements. For instance:
- To bundle or not to bundle. Redshift bundles the compute and storage services, providing instant scalability to enterprise-level if necessary. But Snowflake offers to compute and storage as separate services, and both have tiered editions, which for some businesses might be the more flexible, common-sense solution — you still get the features you need but can scale at any time.
- JSON=Deal? Or no deal? Snowflake offers more robust JSON storage than Redshift, meaning the functions for JSON storage and query are natively built into Snowflake. Redshift, on the other hand, splits JSON into strings upon load, making it much more difficult to query and make use of.
- Security: All you can eat? Or one plate at a time? Redshift's abundant security options allow businesses to customize an encryption solution —but there is a lot of choiceschoice! Snowflake's security and compliance attributes are natively built into each tiered option, so security is a no-brainer: it's there from the moment of integration according to your business's data strategy.
- Data tasks: Done for you? Or DIY? Amazon Redshift needs dedicated maintenance. There are several tasks that Redshift can't automate, like vacuuming data or data compression. That can require a lot of hands-on upkeep. Conversely, Snowflake automates many of these tasks, which can save you significant time if you ever have to diagnose or resolve an issue.
Depending on the level of optimization you need in a data warehouse, gauge the features above. When compared with your data strategy, these features are primary indications of whether the feature offered by Redshift or Snowflake is a benefit or disadvantage for your organization.
Redshift vs Snowflake: Integration and Performance
If your company is already working with AWS, then Redshift might seem like the natural choice (and with good reason). However, you can also find Snowflake in the AWS Marketplace with on-demand functions.
If you already leverage AWS services like Athena, Database Migration Service (DMS), DynamoDB, CloudWatch, or Kinesis Data Firehose (to name a few), the good news is that Redshift integrates seamlessly.
Also, if your data is in Amazon S3, DynamoDB, or Amazon EMR, Redshift can take advantage of Massively Parallel Processing to load your data quickly.
Redshift can also present performance challenges if the Sort and Distribution keys are not planned properly. These keys define how information is stored and accessed in the system. They can be complex to set up and maintain. As an example, once you set a distribution key on a table, it cannot be changed later. Thus, you need to fully understand these concepts before implementing them.
Also worth considering is that, if you use a live app database, Redshift isn't a suitable option. Although it's fast at running queries and analytics on large datasets, it doesn't offer the same performance on live apps. You’ll need to pull the necessary information into a caching layer and subsequently load that into Redshift if you need it for this use case.
However, if you’re thinking of using Snowflake, it’s important to note that it doesn’t have the same integrations as Redshift. This, in turn, makes it challenging to integrate the data warehouse with tools like Athena or Glue.
However, Snowflake makes up for this with a variety of integration options like Apache Spark, IBM Cognos, Qlik, and Tableau, to name a few. As a result, you can say that both solutions are about even. In this respect at least, it's not really a case of Redshift vs Snowflake.
In the Redshift vs Snowflake debate, Redshift is the more established solution, but Snowflake has made significant strides in the past few years.
Data optimization options like materialized views and dist keys mean dashboards have the potential to run up to 150 faster than the source databases.
Redshift vs Snowflake: Database Features
Snowflake makes it quite easy to share data between different accounts. So, if you want to share data with your customers, for instance, you can share it without ever having to copy any of the data.
This is a highly efficient approach to working with third-party data and could become the norm across platforms. But currently, Redshift doesn’t offer the same kind of support, as explained in our tutorial for third-party data management in Redshift. In fact, Redshift doesn’t support semi-structured data types like Array, Object, and Variant. But Snowflake does.
When it comes to Strings, Redshift Varchar limits data types to 65535 characters. You also must choose the column length ahead.
In Snowflake, Strings are limited to 16MB, and the default value is the maximum String size (so there’s no performance overhead). As a result, you don’t have to know the String size value at the beginning of the exercise.
Redshift vs Snowflake: Maintenance
With Amazon’s Redshift, users are forced to look at the same cluster and compete over available resources. In fact, you have to use WLM queues to manage it, and this can be quite challenging when you consider the complex set of rules that have to be understood and managed.
This problem doesn’t exist with Snowflake. You can seamlessly start different data warehouses of varying sizes to look at the same data without copying it. So, these can be allocated to different users and tasks quite easily.
In the Redshift vs Snowflake debate, when it comes to Vacuuming and Analyzing tables regularly, Snowflake wins: it provides a turnkey solution. With Redshift, this can become a problem as it can be challenging to scale up or down.
Redshift Resize operations can also quickly become extremely expensive and lead to hours of downtime.
As compute and storage are separate in Snowflake, you don’t have to copy data to scale up or down. You can just switch data compute capacity at will.
Redshift vs Snowflake: Security
For any successful big data project, security will be at the heart of all activities. However, this can be difficult to maintain consistently as every new data source can potentially open new vulnerabilities. This can lead to a gap between the data that’s being generated and the data that’s being secured.
When it comes to security, it’s not a case of Snowflake vs. Redshift, as both products boast enhanced security. However, Redshift also provides features and tools to manage it like Access management, Cluster encryption, Cluster security groups, Data in transit, Load data encryption, SSL connections, and Sign-in credentials. Access in Redshift can be granularized such that you can grant users or groups access to only the specific data in tables they need for a given task.
Redshift clusters can be launched inside your infrastructure Virtual Private Cloud (VPC). This allows you to restrict inbound or outbound access to your clusters.
Snowflake also offers similar tools and features to ensure security and compliance with regulatory bodies. But you have to be aware of which edition you’re working with as the security features aren’t available across all versions. The base versions offer basic security options, while the options are more robust depending on the version you select. There is a benefit to this method. Using this approach, you can customize your system to purchase only the security features you need.
Redshift vs Snowflake: Costs
Both Snowflake ETL and Redshift ETL have very different pricing models. If you take a closer look, you’ll find that Redshift is less expensive when it comes to on-demand pricing. Both solutions provide 30% to 70% discounts for companies that choose to prepay.
With one-year or three-year Reserved Instance (RI) pricing, you can access additional savings that you’ll miss out on in a standard on-demand pricing model. Redshift calculates costs based on a per-hour per-node basis.
So, you can calculate your monthly commitment as follows:
Redshift Monthly Cost = [Price Per Hour] x [Cluster Size] x [Hours per Month]
Snowflake’s charges heavily depend on your monthly usage pattern. This is because each bill is generated at hour granularity for each virtual data warehouse. Furthermore, data storage costs will also be separate from computational costs.
For example, storage costs on Snowflake can start at an average compressed amount at a flat rate of $23 per terabyte. This will be accrued daily and billed each month. But compute costs will be approximately $0.00056 per second or per credit (on Snowflake on Demand Standard Edition).
However, this can quickly become confusing because Snowflake offers seven tiers of computational warehouses, with the smallest cluster costing one credit or $2 per hour. These costs will double as you go up a level.
An important cost consideration for Snowflake is that, unlike Redshift, it does not need to have a data warehouse up and running just for the ETL part. Using Snowpipe integrated with Snowflake, ETL is not competing with queries for processing. This can reduce the costs as the warehouse can be smaller.
As a result, in the Redshift vs Snowflake debate, it’s safe to conclude that Redshift is less expensive compared to Snowflake'sSnowflake on-demand pricing. But to benefit from significant savings, you’ll have to sign up for their one or three-year RI.
