The document outlines the benefits and functionalities of Azure Data Lake, a scalable data storage and analytics service optimized for big data. It highlights its advantages over traditional on-premises solutions, such as enhanced security, unlimited storage capacity, and flexibility in ingesting various data types. Additionally, it discusses the pricing model, Azure Data Lake's architecture, and the distinction between Azure Data Lake Storage and Azure Blob Storage.

- 2. Move Your On- Prem Data to a Lake in the Clouds
- 3. Agenda • Where are we right now? • Why we need to go for Data Lake? • What is Azure Data Lake? • How do we get there? • Demo • Q & A
- 4. Where are we right now?
- 5. What are the challenges? • Limited storage • Limited processing power • High hardware cost • High maintains cost • No disaster recovery • Availability and reliability issues • Scalability issues • Security • Solution: Azure Data Lake
- 6. What is Azure Data Lake? • Highly scalable data storage and analytics service • Intended for big data storage and analysis • A faster and efficient solution than on-prem data centers • Three services: Analytics Storage HDInsight (“managed clusters”) Azure Data Lake Analytics Azure Data Lake Storage
- 7. Azure Data Lake Architecture
- 8. Azure Data Lake Store • Built for Hadoop • Compatible with most components in Hadoop Eco- systems • Web HDFS API • Unlimited storage, petabyte files • Performance-tuned for big data analytics • High throughput, IOPs • Multiple parts of a file in multiple servers: Parallel reading • Enterprise-ready: Highly-available and secure • All Data, One Place • Any Data in native format • No schema, No prior processing
- 9. Optimized for Big Data Analytics • Multiple copies of same file in improve reading • Locally-redundant (multiple copies of data in one Azure region) • Parallel reading and writing • Configurable throughput • No Limitation in file size or storage
- 10. Secure Data in Azure Data Lake Store • Authentication • Azure Active Directory • All AAD features • End-user authentication or Service-to-service authentication • Access Control • POSIX-style permissions • Read, Write, Execute • ACLs can be enabled on the root folder, on subfolders, and on individual files. • Encryption • Encryption at rest • Encryption at transit -HTTPS
- 11. How to ingest data to Azure Data Lake Store • Small Data Sets • Azure Portal • Azure Power Shell • Azure – Cross Platform CLI 2.0 • Data Lake Tools For Visual Studio • Streamed data • Azure Stream Analytics • Azure HDInsight Storm • Data Lake Store .NET SDK • Relational data • Apache Sqoop • Azure Data Factory • Large Data Set • Azure Power Shell • Azure – Cross Platform CLI 2.0 • Azure Data Lake Store .NET SDK • Azure Data Factory • Really Large Data Sets • Azure ExpressRoute • Azure Import/Export service
- 12. How it different from Azure Blob Storage Azure Data Lake Store Azure Blob Storage Purpose Optimized storage for big data analytics workloads General purpose Use Case Batch, interactive, streaming analytics and machine learning data such as log files, IoT data, click streams, large datasets Any type of text or binary data, such as application back end, backup data, media storage for streaming and general purpose data Key Concepts Contains folders, which in turn contains data stored as files Contains containers, which in turn has data in the form of blobs Size limits No limits on account sizes, file sizes or number of files 500 TiB Geo-redundancy Locally-redundant (multiple copies of data in one Azure region) Locally redundant (LRS), globally redundant (GRS), read-access globally redundant (RA-GRS).
- 13. Azure Data Lake Analytics • Massive processing power • Adjustable parallelism • No server, VM, Cluster to maintain. • Pay for the Job • Use existing .Net, R and Python libraries. • New language : U-SQL
- 14. C#SQL U-SQL • Combination of Declarative Logic of SQL and Procedure logic of C# • Case sensitive • “Schema on Read” U-SQL @ExtraRuns = SELECT IPLYear, Bowler, SUM( string.IsNullOrWhiteSpace(ExtraRuns)? 0: Convert.ToInt32(ExtraRuns) ) AS ExtraRuns, ExtraType FROM @MatchData GROUP BY IPLYear,Bowler,ExtraType;
- 15. How do we go there? Azure Data Factory
- 16. Your feedbacks are essential to me ..!
- 17. Demo/ Q&A
- 18. Pricing • Pay-as-you-go • For a 1 TB storage, for a month = $39.94 • Monthly commitment packages • For a 1 TB storage, for a month = $35 • Usage base: https://azure.microsoft.com/en-us/pricing/details/data-lake-store/ Usage Price Write operations (per 10,000) $0.05 Read operations (per 10,000) $0.004 Delete operations Free Transaction size limit No limit
Editor's Notes
- #5: On prem Lots of data Limited space Maintain the servers Lot of processing power
- #6: Grow hardware on demand Upgrade instantly Availability and readability : Multiple copies of data, Down time for maintains, hardware familiar causes business issues Increase decrease hardware on demand Ability to fail fast, if fail , no need of hardware Ability move into latest technologies Scalability: take time to scale
- #9: Apache Hadoop file system compatible with Hadoop Distributed File System (HDFS) Works with application which support Web HDFS 3 copy in a single IOPS: input output operations per seconds
- #10: Automatically optimized for any throughput
- #14: 250 AU max: 1 AU= 2 core cpu, 6 GB ram Pay As you go: Price: 1 Au for 1 Hour 2$ Monthly : 100 Au , 100$
- #15: Declarative logic Procedure logic sql to query, C# to customize Case sensitive C# data type C# comparison Some commonly used SQL keywords, including WHILE, UPDATE, and MERGE are not supported in U-SQL
- #16: A cloud integration service Workflow called Pipelines Activities in pipeline Integration Run time: self hosted Activities : Copy data, run ssis packages, execute SPs, Execute U-SQL queries Price: no of activity runs and data moment hours Or SSIS runtime based on VM and time
