Operated by Microsoft, Azure is a sophisticated Cloud Computing platform that can be used for analytics, virtual computing, storage, networking services, and more. It also has been one of the pioneers to offer clients end-to-end (storage to deployment) big data solutions. Today, businesses use Azure cloud services like Azure Machine Learning, Azure Data Factory, or Azure Synapse to build, deploy, and manage Machine Learning and Big Data Analytics applications.
What is Azure Synapse?

Azure Synapse provides an End-to-end Analytics Solution by blending Big Data Analytics, Data Lake, Data Warehousing, and Data Integration into a single unified platform. It has the ability to query relational and non-relational data at a petabyte-scale by running intelligent distributed queries among nodes at the backend in a fault-tolerant manner.
Synapse architecture consists of four components: Synapse SQL, Spark, Synapse Pipeline, and Studio. While Synapse SQL helps perform SQL queries, Apache Spark executes batch/stream processing on Big Data. Synapse Pipeline provides ETL (Extract-Transform-Loading) as well as Data Integration capabilities, whereas Synapse Studio provides a secure collaborative cloud-based analytics platform, providing AI, ML, IoT, and BI in a single space.
Synapse also offers T-SQL (Transact-Qequential Query language) based analytics that comprises ‘Dedicated’ and ‘Serverless’ SQL pools for entire analytics and data storage. While the dedicated pool of SQL Servers provides the necessary infrastructure for implementing Data Warehouses, the serverless model empowers unplanned or ad-hoc workloads without setting up data warehouses.
Key Features of Azure Synapse
Some of the key features of Azure Synapse are as follows:
1) Cloud Data Service
Synapse offers Data Warehousing, Machine Learning, Data Analytics, and Dashboarding service in a single workspace on the cloud. This ecosystem performs ETL, supports advanced ML algorithms, and visualizes data with Microsoft Power BI.
2) Supports Structured and Unstructured Data
Unlike data warehouses and data lakes that store relational and non-relational data respectively. Synapse powers businesses by handling relational and non-relational data like tabular, LOB, CRM, Graph, Image, Social, or IoT data under the same roof.
3) Effective Data Storage
As Synapse performs Big Data analytics, it uses Azure Data Lake Storage Gen 2 (ADLS Gen2) to provide storage solutions. ADLS Gen2 is combined with Azure Blob to offer next-level data storage that has high data availability and tiered data storage.
4) Responsive Data Engine
Irrespective of what data storage methods are accompanied, enterprises expect blazing results. Synapse provides Massive Parallel Processing (MPP) to handle analytical workloads and aggregate processes for large volumes of data efficiently.
5) Language Compatibility
As Synapse handles various data analysis and engineering profiles, it supports a wide range of scripting languages. Azure Synapse is compatible with multiple programming languages like Scala, Python, Java, SQL, or Spark SQL.
6) Query Optimization
Query concurrency has been a challenge for any analytics system. However, Synapse facilitates limitless concurrency and performance optimization. In addition, workload management is readily simplified in Synapse by prioritizing important queries. For instance, if the ‘CEO’ of a company runs a query, then such queries are automatically promoted instead of queuing them.
What is Databricks?

Databricks is a Cloud-based Data Engineering tool for processing, transforming, and exploring large volumes of data to build Machine Learning models intuitively. Currently, the Databricks platform supports three major cloud partners: AWS, Microsoft Azure, and Google Cloud. Azure Databricks is a jointly developed first-party service from Microsoft that can be accessed with a single click on Azure Portal.
Organizations find it challenging to handle big data because it requires an integration of various tools. However, Databricks facilitates a zero-management cloud platform that is built around Spark cluster to provide interactive workspace. It enables Data Analysts, Data Scientists, and Developers to extract values from big data efficiently. In addition, it seamlessly supports third-party applications such as BI and domain-specific tools for generating valuable insights. Large-scale enterprises utilize this platform for a broader spectrum to perform ETL, data warehousing, or dashboarding insights for internal users and external clients.
Enterprises operate their Data Warehouses independently of Data Lakes. While the former helps to derive valuable business insights, the latter is used for storage and data science applications. Databricks has a ‘Lake House’ architecture that leverages data lake and data warehouse elements to provide low-cost data management. This architecture facilitates ACID (Atomicity, Consistency, Isolation, and Durability) transaction, robust data governance, decoupled storage from computation, and end-to-end streaming.
The Lakehouse platform streamlines data, AI, and analytics in one platform to perform traditional SQL analytics, BI, as well as data science and machine learning applications. Although users of Lakehouse have access to a variety of standard tools (Python, Spark, or R), Delta Lake provides an open file format (parquet) to track version changes while offering data management capabilities. A Delta Lake is a Lake House architecture built on top of the data lake that provides an open format storage layer for both streaming and batch operations. Such open data file format simplifies data accessibility for data scientists as well as machine learning engineers to implement ML applications using some popular tools like pandas, TensorFlow, or PyTorch.
Key Features of Databricks
Some of the key features of Databricks are as follows:
1) Language Compatibility
While Azure Databricks is Spark-based, it is also compatible with programming languages like Python, R, and SQL for use. These languages are converted to Spark at the backend through APIs, allowing users to work in their preferred programming language.
2) Productivity and Collaboration
With Databricks, organizations can create an environment that offers a collaborative workspace between data scientists, engineers, and business analysts. Such interaction among multiple members brings novel ideas during the early stages of Machine Learning Applications life cycle. Additionally, version control of a source code becomes a painless task as all involved users have access to ongoing projects.
3) Connectivity
Apart from cloud-based services, Databricks easily imports CSV or JSON files and connects to SQL servers. It also bridges data sources like MongoDB, Avro files, and many others.
