What Is Snowflake?

Snowflake is a wholly managed SaaS and a cloud-based data warehousing platform, enterprise-ready software. We can flexibly run Snowflake on cloud service providers like Google Cloud, Amazon AWS, Azure, etc. It runs wholly on the public cloud infrastructure and supports data warehousing, data engineering, creating data apps, etc.

It is prevalent for its data-sharing feature. Snowflake architecture includes the following key components:- Cloud Services, Database Storage, and Query Processing. The major benefit of using Snowflake for users is that there is no need to engage people to install and manage it and to spend money to set it up. However, the Snowflake solution divides the compute functions and storage, enabling clients to use and pay for them individually. 

Moreover, we can connect Snowflake with other services in different ways. It includes web-based UI, command-line clients, and drivers (ODBC & JDBC) through BI and ETL tools.

Why use Snowflake?

Snowflake is very fast, flexible, and offers user-friendly features to use. It is a popular enterprise-ready software that uses an SQL database engine with a cloud-based architecture. Also, it overcomes the features of many traditional data warehouses. We can also use Snowflake as a data warehouse and a data lake. The data cloud feature allows us to connect and collaborate locally and globally to discover new insights. 

Moreover, Snowflake is an ideal solution for many companies because it offers great speed with superb performance. It provides faster processing of queries with automatic query optimization techniques. Also, it offers a user-friendly interface for both technical and non-tech people. Like traditional data warehouses, there are no administrative costs required for managing Snowflake. 

It is why this SaaS platform is trendy among many giant companies across the globe. 

Snowflake Data Warehouse:

Snowflake is a multi-cloud data platform in the truest sense. They can provide their customers with high availability and secure data across three clouds and multiple regions. Snowflake is available on Amazon Web Services, Microsoft Azure, and Google Cloud Platform. With Snowflake, you have a technology solution to build a scalable, highly resilient cloud environment with the agility your business requires while delivering valuable results.

Because of Snowflake's unique architecture and the cloud's flexibility, customers can use Snowflake across a wide range of use cases and workloads.

Snowflake began as a Data Warehouse, but as the company's ability to manage more and more data types grew, customers began to use Snowflake as a SQL Data Lake.

Customers could also use the Snowflake Data Exchange to firmly access content within their organizations as well as with various data partners. This significantly improves their own datasets, allowing them to run more sophisticated and powerful Data Analytics besides Data science use cases.

What is BigQuery?

BigQuery is also an enterprise-ready data warehouse from Google, which is serverless, the most cost-effective, and has multi-cloud features. It helps to analyze and manage data using many in-built features such as ML, BI, geospatial analytics, etc. Further, it also separates the computing and storage platforms. Many large-scale companies use it, such as P&G, CNA, Toyota, UPS, etc.

Moreover, Google BigQuery comes with an in-built query engine feature that runs massive in a fraction of a second. We can get this speedy performance without the need to rebuild indexes. It analyzes billions of rows of data using a syntax similar to SQL. It is used in a Dremel form inside the Google platform. It helps track device installation data, spam check, and build crash reports. 

It is also similar to Snowflake, which doesn't need to set up and manage infrastructure. Moreover, it is completely based on Google and doesn't support or run on any other platform. 

Why Use BigQuery?

BigQuery is Google's serverless data warehousing platform that helps you achieve unmatched performance. It also includes some features similar to Snowflake, such as faster performance, a serverless data warehouse, provides real-time analytics with fast streaming, high availability with security, and holds a flexible pricing structure.

Snowflake Vs BigQuery:

Choosing the best data warehouse for your company's needs and goals is a critical component of your big data strategy. We can see that these two data warehouses are closely stacked because they both have extensive feature sets.In terms of functionality, the leading industry standard TPC Benchmark shows little difference between Snowflake vs BigQuery. They both provide limitless concurrency and total elasticity. As a result, we chose to score this primarily on cost.

Architecture

Snowflake

Snowflake is a fully serverless solution with cloud-based data warehousing infrastructure. It isolates the storage and computing from each other. Further, its architecture is hybrid, and it is a multi-clustered shared data system. It delivers all the entity's needs, such as high performance, elasticity, scaling, etc.

Snowflake uses a central repository system that helps to make your data available throughout the compute nodes in the system. Moreover, the data inserted into Snowflake is reinvented, optimized and abridged to make a columnar form. The same is stored in the cloud storage. 

Furthermore, it manages various aspects of data storage like file size, metadata, statistics, format, etc. We can only access them using SQL queries. Also, Snowflake uses virtual data warehouses to process the data. 

BigQuery

It is Google's serverless data warehousing system with cost-effective features. It shares some features that are equal to the Snowflake platform. But the architecture system of BigQuery is something different than Snowflake. It uses a set of multi-tenant services which are based on popular Google-driven technologies like Dremel, Jupiter, Colossus, etc. BigQuery uses the Dremel technology, a vast multi-tenant computing cluster for the computing process. It helps to execute various SQL queries within BigQuery. 

Moreover, Google's global repository system "Colossus" helps store data and manages data recovery, replication, and data management. It ensures that users don't rely on any point of failure in the system. Further, the hardware system's complete interpretation and resource distribution is handled by Borg, Google's pioneer in the Kubernetes tool. Google's Jupiter also helps in faster data movement across locations.

Pricing

Snowflake

The pricing models of Snowflake are based on each warehouse's usage. Therefore, its charges are wholly based on the total usage of the data storage system. Further, it has different types of warehouses, which broadly vary based on size and cost. Snowflake's standard edition costs are calculated on a one-credit/hour basis, where the cost per credit is USD 2. But depending on the business, the costs may vary. The cost of credit consumption may increase with the increasing size of the warehouse. Snowflake's upfront costs are comparatively lower than the on-demand cost. So, it is preferred by most entities. 

BigQuery

The pricing model of BigQuery is something different from Snowflake. Google's BigQuery offers a flat-rate pricing system with an on-demand pricing option. It charges for the number of bytes it scans or reads. Also, the on-demand pricing system of BigQuery includes USD 5/TB for the number of bytes scanned or processed. On the other side, the flat rate system is followed by the slots we buy to execute the queries. It costs around USD 2000/100 slots.

Performance

Snowflake

Performance-wise, both Snowflake and BigQuery are similar. Snowflake outperforms with faster performance and querying times. It loads massive volumes of data from on-premise to cloud space quickly with faster loading. It uses the command "COPY" to load data into Snowflake. Also, it rapidly transforms broad raw data into meaningful queries. Further, it reduces the latency time for each query by speeding up the querying process.

BigQuery

It is a strong competitor of Snowflake in terms of performance. BigQuery holds several dedicated hard drives that can read around 1TB of data within a fraction of a second. Query performance optimization helps entities minimize costs. Also, it improves query speed to enhance performance. By purchasing more reserved slots, we can benefit from improved query performance. 

Administration

Snowflake

Snowflake doesn't impose huge admin costs compared to others. It is designed to execute with minimal supervision of a Snowflake Admin. Auto-scaling is the essential feature that enhances or decreases the size of a virtual data warehouse. It is based on its existing workload. 

BigQuery

BigQuery, similar to Snowflake, also allows us to manage various permissions, roles, and data security. Its automatic performance tuning system allows us to deal with large data volumes. With the growing data volume, the queries have also become much more complex. By addressing the various needs, it automatically scales each platform. Therefore, it manages all the maintenance automatically. 

Management and Maintenance

Snowflake

Snowflake allows us to manage data processing and storage quickly, and makes solutions faster, easy usage, and more highly flexible than traditional methodologies. An advanced SaaS data platform powers it. Further, it effectively manages the data security and encryption of the stored data. Also, it maintains complete certifications relating to data warehousing, such as DSS, HIPAA, etc. It manages all the data on cloud infrastructure with full scalability and elasticity.

BigQuery

It also allows us to manage data repository, processing, solution development, and flexibly use the platform. Moreover, Bigquery manages different data types more efficiently and centrally manages, monitors, and controls data across warehouses and data lakes with remarkable consistency. It also offers easy maintenance of services.

Data Protection

Snowflake

When it comes to protecting crucial business data, both Snowflake and BigQuery perform well. Snowflake offers two distinct features to protect data: Fail-Safe and Time-travel. Time travel is used to secure the position of the data before it gets updated. There is a one-day general holding time frame for Time travel, whereas the enterprise edition allows mentioning 90 days time frame. On the other side, using the Fail-safe feature, Snowflake tries to recover the historical data which is lost or damaged. It immediately begins when the Time travel period ends. 

BigQuery

In the case of BigQuery, the admins can make changes to data without worrying about recovery. It generally manages a seven-day history of all the data changes within a table. Moreover, to keep data for more than seven days, it uses table snapshots to protect data. 

Security

Snowflake

Security is the central part of any data warehouse, without which no one can store or recover data safely. Snowflake allows the most trusted features for data security. It secures all the inserted data into the tables using AES encryption. All the files are auto-encrypted through the AES encryption system. Further, it provides granular permissions for schema, views, objects, tables, processes, etc., rather than individual columns. 

BigQuery

It also has a set of rules for data security where it supports OAuth 2 and a multi-factor validation system similar to Snowflake. It is used for authorized access to accounts. It also provides federated user access through the Microsoft Active Directory (MAD). Further, it provides permissions only to datasets and not to individual tables or views. 

Ease of Use

Snowflake

It is highly recognized for its ease of use and intuitive interface. We can immediately start using the service without disturbing the other tasks and automatically compute clusters of different sizes for any user. Also, it ensures the delivery of the performance that an organization expects. 

BigQuery

Being a serverless platform, BigQuery automatically supplies additional computing resources on a required basis. By doing so, it manages massive data workloads. All this makes it easier to process massive amounts of data in just a few minutes. 

Scalability

Snowflake

It offers an auto-scaling and auto-suspend feature that allows clusters to start or stop the process from managing workloads dynamically. Through this feature, users can resize the clusters with a single click. Further, we can autoscale upto 10 data warehouses within a single table. 

BigQuery

It also performs similarly to Snowflake, which supplies additional computing resources based on need. Also, it manages everything in the background. Therefore, it processes large-scale data and improves scalability. Further, it allows 100 parallel users by default.

Compliance

Snowflake

Snowflake is highly dedicated to meeting regulatory compliance needs to provide better customer service. It ensures data integrity, control, and security. It uses ITAR compliance to support its customers, especially in the US region. However, Snowflake meets the compliance needs for HIPAA, PCI DSS, SOC 1 & 2 Type II, FedRamp Moderate, etc. 

BigQuery

BigQuery also meets the compliance needs of HIPAA, PCI DSS, SOC 1 & 2 Type II, etc. Since BigQuery is a Google native, it provides the benefits of Google Cloud Services with proper authentication and built-in security. Therefore, it makes various integrations much more effortless.
