Agenda • Azure Blob Storage • Azure Table Storage • Azure CosmosDB • Azure SQL Database • Azure SQL in a VM • Azure SQL Data Warehouse • Azure Data Lake • Lots of other things supported: • Postgres, MySQL, MongoDB, Redis
Topic Agenda • What is it? • How is it used? • What are the competitors? • DEMO!
Azure Blob Storage
Azure Blob Storage • Blobs are files (PDFs, JPGs, DOCs, etc) • Highly durable, massively scalable • More than 40 trillion stored objects • 3.5+ Million requests/second • Exposed via REST APIs • Use them in .NET, C++, Java, Node.JS, Android… • AzCopy, PowerShell
Blob Storage Fault Tolerance & Scalability
What kind of blobs can I have? • Share files with clients • off-load static content from web servers (invoices, contracts, resumes) • Azure Websites – Platform as a Service – no files on a webserver • SQL BAK Files • VM Hard Drives
Competitors? • On premise SANS and arrays • Amazon S3 Blob Storage
Azure Blob Storage Demo
Azure Table Storage • Much of it similar to Azure Blob Storage • Same scalability & redundancy • Affordable price • Very, very fast • NoSQL key value pair solution • Quick data retrieval, little configuration
Competitors • Amazon DynamoDB Table Storage
Azure Table Storage Demo
JSON Document Standard for passing data between a server and a web application Replacement for XML Hierarchical Terse Simple data types
Modeling in CosmosDB { "id": "1", Reading is one operation "firstName": "Thomas", Writing is one operation "lastName": "Andersen", No assembly de-assembly "addresses": [ { "line1": "100 Some Street", "line2": "Unit 1", "city": "Seattle", "state": "WA", "zip": 98012 } ], "contactDetails": [ {"email: "thomas@andersen.com"},
Query Playground http://www.documentdb.com/sql/demo
Competitors • MongoDB • Amazon DynamoDB
Azure SQL Database • Platform as a Service • All data is backed up for you • Point in time restore • Can be geo-redundant • Scalable both in performance and in data size • Up to 1TB • Not feature complete with SQL Server in a VM
Database Replicas
Azure SQL Database Unsupported Features https://azure.microsoft.com/en-us/documentation/articles/sql-database-transact- sql-information/
You can also make it scale up!
Competitors Amazon RDS
Azure SQL Database Demo
Azure SQL Server in a VM • You manage backups • You create fault tolerant options • You manage disk space • You manage patching • You don’t manage hardware failure • You don’t manage purchasing hardware • You don’t manage networking infrastructure
Performance Considerations • Use Premium Storage. • Use a VM size of DS3 or higher for SQL Enterprise edition and DS2 or higher for SQL Standard edition. • Use a minimum of 2 P30 disks (1 for log files; 1 for data files and TempDB ). • Keep the storage accountand SQL Server VM in the same region. • Disable Azure geo-redundant storage (geo-replication) on the storage account. • Avoid using operating system or temporary disks for database storage or logging.
Backups & Fault Tolerance • Back up to Azure Blob Storage • Use Always on Availability Groups and Windows Failover Clustering Services (WFCS) for fault tolerance • Can use mirroring or log shipping too • Can also mix in on-premise
Competitors Amazon EC2 – VMs in the cloud
Azure SQL Data Warehouse • Elastic Massively Parallel Processing System • Use T-SQL to query across relational and non-relational data • Up to petabyte volumes of data • Scale compute separately from data • When paused, you only pay for storage • Deploys in seconds
Azure SQL Data Warehouse • Supports 32 concurrent queries • Used for fanning out queries over multiple machines for processing/aggregation/analytics • Performance becomes far more predictable than with just straight SQL Server • Not used in OLTP environments
What is a DTU (Data Warehouse Unit)? • A unit of scale that determines how much hardware will give great performance • Done in increments of 100 (mostly) • How many DTUs? • Start Small • Monitor • Change as needed. It’s instant. ALTER DATABASE MySQLDW MODIFY (SERVICE_OBJECTIVE = 'DW1000') ;
Partitioning Data Two choices: • Distribute data based on hashing values from a single column • Good if clusters of tables will be joined and are related • Distribute data evenly but randomly • Fail-safe method
Non-supported data types • geometry, use a varbinary type • geography, use a varbinary type • hierarchyid, CLR type not native • image, text, ntext when text based use varchar/nvarchar (smaller the better) • nvarchar(max), use varchar(4000) or smaller for better performance • numeric, use decimal • sql_variant, split column into several strongly typed columns • sysname, use nvarchar(128) • table, convert to temporary tables • timestamp, re-work code to use datetime2 and CURRENT_TIMESTAMP function. • varchar(max), use varchar(8000) or smaller for better performance • uniqueidentifier, use varbinary(8) • user defined types, convert back to their native types where possible • xml, use a varchar(8000) or smaller for better performance - split across columns if needed
Unsupported Features • primary keys • user-defined types • foreign keys • indexed views • check constraints • identities • unique constraints • sequences • unique indexes • triggers • computed columns • synonyms • sparse columns
Competitors Amazon RedShift
Azure SQL Data Warehouse Demo
Azure Data Lake HDFS for the cloud Can use tools like Spark, Storm, Flume, Sqoop, Kafka, etc. No fixed limits on account size or file size
What is a generic data lake? • An enterprise wide repository of every type of data collected in a single place • Prior to any formal definition of requirements or schema. Allows every type of data to be kept without discrimination Organizations can then use Hadoop or advanced analytics to find patterns of the data. • Serve as a repository for lower cost data preparation prior to moving curated data into a data warehouse.
Products • Azure Data Lake Store – Built on HDFS • Azure Data Lake Analytics – Built on Yarn. Introduces U-SQL/C# 45
Competitors A lot of Hadoop implementations, but nothing really quite like it 46
More data options…. • MongoDB • PostGres • Redis • MySQL • Oracle 47
