Why Snowflake
The primary reason for using Snowflake is to simplify complex data architectures. Traditional systems often require a lot of administrative effort: capacity planning, index tuning, maintenance, and manual scaling.
Snowflake takes a different approach. The platform is designed so teams can focus on data models, analytics, and use cases, not infrastructure.
Key reasons for using Snowflake include:
- High scalability without system interruptions
- Easy to use via SQL and familiar interfaces
- Low administration costs as maintenance is automated
- Central database for BI, analytics and data science
- Share data securely and easily between teams and organizations
This makes Snowflake particularly attractive for companies that need to process rapidly growing amounts of data or support many different data users.
Snowflake Architecture
A key unique selling point of Snowflake is its multi-layered architecture, which clearly separates storage, computing power, and services. This design is critical for performance, scalability, and flexibility.
1. Storage layer
All data is stored centrally in the cloud in a column-oriented format that is optimized for analytical queries. Snowflake automatically compresses, encrypts, and organizes the data. Users don't have to worry about partitioning or indexes. The platform automatically optimizes storage.
2. compute layer (virtual warehouses)
The computing power is provided via so-called virtual warehouses. These are computing clusters that are independent of each other and carry out queries and data processing tasks.
The big advantage is that several virtual warehouses can access the same data in parallel without slowing each other down.
Virtual warehouses can be flexibly scaled, paused or started automatically, which enables very fine-grained cost control.
3. cloud services layer
This layer coordinates the entire system and performs central control tasks such as authentication and access control, metadata management, query optimization, and transaction management.
It represents the central control and communication level through which all user interactions with Snowflake are handled.
More services and features
Snowflake is more than just a data warehouse. Over the years, the platform has been expanded to include numerous functions.
Snowpipe
A service for continuous data collection. This allows new data to be automatically loaded as soon as it is stored in cloud storage.
Time travel and fail-safe
Snowflake stores previous versions of data for a specific period of time. In this way, accidentally deleted or modified data can be recovered.
Secure data sharing
Data can be shared with other Snowflake accounts in real time without the need to copy or export it. This is particularly valuable for cross-company collaboration.
Snowpark
With Snowpark, developers can perform data processing in languages such as Python, Java, or Scala directly within Snowflake. This enables complex data logic and data science workflows without moving data out of the platform.
Marketplace
External data sets from third-party providers can be easily integrated and used via the Snowflake Data Marketplace.
Benefits of Snowflake
Snowflake offers a number of benefits that set it apart from traditional solutions:
1. Separation of storage and computing power
Resources can be scaled independently, which enables high flexibility and efficiency.
2. Easy scalability
More performance can be delivered within a few seconds without migration or system downtime.
3. Low operating costs
Maintenance, optimization, and infrastructure management are largely automated.
4. Support for modern data formats
Semi-structured data can be processed directly, without complex pre-transformation.
5. Strong performance for analytics
Thanks to column-based storage and automatic optimization, even large amounts of data can be efficiently retrieved.
6. Secure data sharing
Data can be controlled and shared without duplicates.
Disadvantages of Snowflake
Despite many strengths, Snowflake isn't the perfect solution in every scenario.
1. Cost model can be complex
By billing storage and computing power separately, costs can quickly rise when used uncontrollably.
2. High costs for complex processes
Complex transformations, large joins, and frequent ELT jobs significantly increase compute consumption and make Snowflake expensive without optimization.
3. Strong cloud dependency
Snowflake is purely cloud-based and therefore unsuitable for strict on-premises strategies.
4. Less control over infrastructure
As a fully managed service, Snowflake offers only limited options for deep system customization.
5. Vendor lock-in
The strong connection to the Snowflake ecosystem can make a later platform change complex and expensive.
6. Additional costs for data transfers
Moving large amounts of data out of Snowflake involves additional egress and transfer costs.
7. SQL focus
Snowflake is heavily SQL-oriented, which makes specialized big data frameworks elsewhere more flexible.
8. More compute instead of optimization
Performance problems are often solved by scaling up computing power instead of efficient queries, which increases costs in the long term.
When is Snowflake worthwhile?
Snowflake is particularly worthwhile in the following scenarios:
- When large and growing amounts of data need to be processed
- When many different teams access data at the same time
- When rapid scaling is required without infrastructure projects
- When data from different sources is to be brought together centrally
- When data needs to be shared securely with partners or customers
Snowflake is less suitable for very small, static data environments or organizations with strict guidelines against cloud solutions.
Conclusion
Snowflake has established itself as one of the leading cloud data platforms because it significantly simplifies complex data infrastructures. By clearly separating storage, computing power and services, it offers high flexibility, strong performance and almost unlimited scalability.
At the same time, the platform significantly reduces administrative effort, allowing data teams to focus more on analysis, innovation, and business value. For modern, data-driven companies, Snowflake is therefore in many cases a future-proof basis for analytics, data engineering and data science.
