Introduction
In today’s modernizing world, data has become one of the most vital necessities for everyone. It doesn't matter if the user and the provider both need the data in their way and if they are consuming data and performing operations accordingly. They must have a place to store the data.
Either small or big firm of them has their databases. The main challenge most firms or companies face in starting is having a data warehouse of their own. Earlier, purchasing a data warehouse was a very expensive task. With the space to store data, you also need proper software and application to analyze the data correctly.
That’s where snowflake comes into play. We will learn all about snowflake while moving further in the blog. So without wasting any further time, let’s proceed with our topic.
Snowflake and its Features
Snowflake saves your space, storage for creating data warehouses, data marts, data lakes, etc. Snowflake is a cloud-based platform used to eliminate the need for data warehouses and other stuff.
It is based on the top of Microsoft Azure, Amazon Web Services, Google Cloud infrastructure. There is no software or hardware to install, select, manage, or configure, and because of that, most companies don't want to spend their resources setting up and maintaining the servers. So snowflake takes advantage in this case as we can quickly move the data in the snowflake using Stitch, which is an ETL solution.
Its data sharing capabilities and architecture make it different. Its storage allows computing and storage to scale independently, making it very useful for customers as they can pay for computing and storage alone.
It also has a sharing feature that makes it more trustworthy among companies.
Earlier, when you purchase the infrastructure, then you have to buy the content along with it, for example, buying the cable TV connection earlier, you have to buy the content with the infrastructure, but with the use of snowflake, the user has control over what they need and then pay accordingly.
All the companies don't have the same need. Some need more storage and minor CPU cycle and vice versa. So they need not pay for integrated bundles, and users can pay for only the resources they use. Time is calculated in seconds, whereas storage is calculated with the terabytes stored per month.
Architecture of Snowflake
Architecture defines or describes the structure of the software. Snowflake is mainly made of three layers Storage, compute, and services, and each of them is independently scalable.
Database Storage
As the name suggests, it is a database containing all the data loaded in snowflake, including semistructured and structured data. Snowflake automatically manages all the aspects of data storage, i.e., file size, organization, compression, structure, statics, and metadata. The database layer runs independently from any other layer like compute layer.
Compute Layer
The compute layer comprises warehouses, not real warehouses but virtual warehouses, and they execute the data processing task required by queries. Each virtual cluster or warehouse can access all the data present in the above layer, i.e., the storage layer. After getting the data to work independently, warehouses cannot compete for computer resources. This has many advantages, like automatic scaling enabling non-disruptive, which means compute resources can rebalance or redistribute the data in the storage layer while the queries are running.
Cloud Services
The cloud service is the third layer in the architecture that coordinates the entire system and uses ANSI SQL. It is beneficial as it eliminates the requirement of manual data warehouse tunning or synchronization. The services in this layer include:
- Authentication
- Metadata management
- Access control
- Query parsing and optimization
- Infrastructure management.
Advantages of Snowflake
Snowflake is built to solve many problems users or providers face in hardware warehouses, such as data transformation, failure, or high query volume delays. It uses the cloud to solve these problems. Below are some of the benefits or advantages that snowflake gives us:
Performance and Speed
We can store as much data in the cloud according to our requirements, whether it is large or small, and because of this, it is referred to be elastic. It is also known as a virtual warehouse, and you can take advantage of this in computing faster and better. You can pay for the virtual warehouse only when you use it, which is also cost-effective.
Accessibility and Concurrency
In an old method of warehouses like traditional hardware warehouses, the issues regarding concurrency will be standard, leading to failures and delays when a large number of queries come at the same time.
Snowflake resolves this problem with the help of its unique multicluster architecture. In this, the queries from one virtual warehouse do not interfere with any other question, and because of this, data scientists can get the result of what they want without waiting for the whole process to complete.
Availability and Storage
Snowflake is readily available to everyone. It is divided into different platforms like AWS, azure. It is designed to work consistently and can tolerate error like network failures, and can solve it with just a minimal effect on customers. It has a different level of security, such as encryption on all network communication are done.
Seamless Data Sharing
The architecture of snowflake allows data sharing among snowflake users. It also will enable organizations to share data with their customers or non-customers. It can use a reader account for non-users, and with the help of this, they can create a snowflake account.
