Azure Databricks seamlessly integrates with existing Microsoft cloud services and provides a rich set of built-in and AI powered analytics services. For example, teams can multi-function in terms of operating or processing massive datasets because everything is in one place. Here's a breakdown of how it works:
Clusters: Azure Databricks processes data by using sets of virtual machines as its computation engines. These clusters process user data in parallel, which enables them to deal with heavy workloads effectively and fast.
Notebooks: These serve as interactive user interfaces where users can interactively code and run segments of code. These notebooks are tailored for team-based work in such disciplines as data science or machine learning because ,unlike traditional notebooks, they support multiple programming languages like Python, Scala, and even SQL.
Jobs: These are automated tasks aimed at accomplishing a certain goal. Such automation is particularly beneficial for tasks that require frequent execution ,such as ingestion of data, ETL processes (Extract, Transform, Load), or even model training. With these automations, the user is able to engage in higher level tasks that add more value to the organization.
Compute and Storage
Compute Resources: These are powered by Azure’s virtual machines, and thus, the platform incurs an extra fee for workloads. The total cost incurred will also be calculated in relation to the selected VMs type and size.
Storage: Data is stored separately in Azure services like Blob Storage or Data Lake. These storage options provide security, scalability, and are independently charged from compute resources, guaranteeing data availability regardless of workload size.
Deep Dive into Azure Databricks Pricing Structure
Azure Databricks has adopted a pay-as-you-go spending model, which charges users for resources consumed. Below are the key components of its pricing structure:
Databricks Units (DBUs): Core billing unit representing processing power. DBUs are charged as the compute is used, on a per-second basis.
VM Costs: Charges for a specific Databricks cluster's virtual machine type.
Storage: Costs for cloud storage services such as Azure Data Lake.
Networking: Extra costs associated with networking infrastructure, maintenance, and data transfers.
Azure Databricks Pricing Tiers
Azure Databricks offers two main pricing tiers, with additional features like Enterprise available in select regions or through special agreements:
Standard: Basic analytics, job monitoring and scheduling, notebooks, autopilot clusters, integration into other tools of the ecosystem, etc, are offered. Small businesses and users with simple workflows at a value-oriented price would find this tier useful. Users should note that this may be the last region where this tier is available, as premium becomes the default.
Premium: Standard services are available with the addition of RBAC, audit logs, credential passthrough, Delta Live Tables, advanced security, and compliance customization. Designed for medium to large companies for use by their regulated business units, within cross-functional teams.
Enterprise: (Available in select regions or via negotiation) Offers sophisticated compliance, data governance, and enhanced support. Tailored for larger corporations and deeply regulated sectors.
DBUs Explained with Costs
DBU pricing varies by workload type, tier, and region. Below are the example prices for the US East region (actual prices may differ):
Workload Type | Tier | DBU Price (per hour) |
Jobs Compute | Standard | $0.15 |
All-Purpose Compute | Standard | $0.40 |
All-Purpose Compute | Premium | $0.55 |
SQL Compute | Premium | $0.55 |
Serverless SQL Compute | Premium | $0.70 |
DBU Consumption:
Consumption of DBUs increases with the type of virtual machine and its load. For example, a D4s v3 VM might spend 1 DBU per hour for Jobs Compute. As with more complex tasks, larger VMs incur higher costs in DBUs.
Example Pricing Calculation
Cost Breakdown for Jobs Compute Workload (Standard VM D4s v3, US East Region)
VM cost per hour: $0.564 (example price; verify with Azure Pricing Calculator)
DBUs consumed per hour: 1 DBU
DBU cost per hour: $0.15
Total cost per hour: $0.564 (VM) + $0.15 (DBU) = $0.714
Cost Breakdown for All-Purpose Compute Workload (Premium Tier, Standard VM D4s v3)
VM cost per hour: $0.564
DBUs consumed per hour: 1.5 DBUs (example; depends on VM and workload)
DBU cost per hour: $0.55 × 1.5 = $0.825
Total cost per hour: $0.564 (VM) + $0.825 (DBU) = $1.389
Note: Storage and networking costs are billed separately and should be included for a full estimate.
Additional Pricing Benefits
Azure Databricks has various options to save costs and assist companies in budget optimization:
Pre-Purchase Commit Plans (DBCUs)
Pre-purchase DBCUs for 1 or 3 years and save up to 33% (1-year) or 37% (3-year).
DBCUs are deducted as you use DBUs, regardless of workload or tier, offering flexibility throughout the term.
Example: Using 10,000 DBUs under a commit plan at $0.35/DBU (vs. $0.55/DBU pay-as-you-go) saves $2,000.
Reserved Instances: Get up to 72% on certain types of VMs for varying durations from 1-3 year contracts of Azure VMs.
Spot Instances: Serve non-critical workloads that are interruptible, such as batch jobs or data processing. Access to unused Azure space comes at a discount of as high as 90%.
Comparing Azure Databricks Pricing
Looking at Snowflake and AWS Databricks in comparison to Azure Databricks shows some important distinctions:
Azure vs. AWS Databricks: Both use DBU and VM-based billing, but pricing and VM selection differ per region and provider. Generally, Azure has comparable or better reserved instance discounts.
Azure Databricks vs. Snowflake: Snowflake charges for computing using a credit system and a pay-per-second method, charging storage separately. While Databricks is more expensive for SQL analytics done solely, it favors mixed workloads.
