On AWS you can choose from a variety of managed database services that save effort, save time, and unlock new capabilities and economies. In this session, we make it easy to understand how they differ, what they have in common, and how to choose one or more. We'll explain the fundamentals of Amazon RDS, a managed relational database service in the cloud; Amazon DynamoDB, a fully managed NoSQL database service; Amazon ElastiCache, a fast, in-memory caching service in the cloud; and Amazon Redshift, a fully managed, petabyte-scale data-warehouse solution that can be surprisingly economical. We will cover how each service might help support your application, how much each service costs, and how to get started.

Learning Objectives:
• Overview of managed database services available on AWS
• How to combine them for high-performance cost effective architectures
• Learn how to choose between the AWS database services based on the use case

Who Should Attend:
• IT Managers, DBAs, Enterprise and Solution Architects, IT Managers, DBAs, Enterprise and Solution Architects, Devops Engineers and Developers

Getting Started with Managed Database Services on AWS - September 2016 Webinar Series

  1. 1. © 2015, Amazon Web Services, Inc. or its Affiliates. All rights reserved. Prahlad Rao, Solutions Architect Sept 29th 2016 Managed Database Services on Amazon Web Services
  2. 2. Today’s agenda • Why managed database services? • A non-relational managed database • A relational managed database • A managed in-memory cache • A managed data warehouse • What to do next
  3. 3. Why managed database services?
  4. 4. Options for running your database • Self-Managed—You are responsible for the hardware, OS, security, updates, backups, replication etc., but have full control over it. This is typically on premise. • EC2 Instances—You only need to focus on the database level updates, patches, replication, backups etc. and don’t have to worry about the hardware and underlying infrastructure. • Fully Managed—You get features such as backup and replication etc. as a package service and don’t have to bother with patching and updates.
  5. 5. What are the AWS managed DB options?
  6. 6. A managed service for each major DB type Amazon DynamoDB Document and Key- Value Store Amazon RDS SQL Database Engines Amazon ElastiCache In-Memory Key-Value Store Amazon Redshift Data Warehouse
  7. 7. Pick the best tool for the job
  8. 8. What is Amazon RDS?
  9. 9. Relational databases Fully managed Fast, predictable performance Simple and fast to scale Low cost, pay for what you useAmazon RDS Amazon Aurora
  10. 10. Use cases Applicable wherever you need relational databases eCommerce Gaming Websites IT Solutions Apps Reporting

  12. 12. Amazon RDS is simple and fast to scale Database instance types offer a range of CPU and memory selections Scale up or down among instance types on demand Database storage is scalable on demand
  13. 13. Amazon RDS offers fast, predictable storage General Purpose (SSD) for most workloads Provisioned IOPS (SSD) for OLTP workloads up to 30,000 IOPS Magnetic for small workloads with infrequent access
  14. 14. High availability Multi-AZ deployments Enterprise-grade fault tolerance solution for production databases
  15. 15. Choose Read Replicas for greater scalability Bring data close to your customer’s applications in different regions Relieve pressure on your master node for supporting reads and writes. Promote a read replica to a master for faster recovery in the event of disaster
  16. 16. Choose cross-region replication for enhanced data locality, even more ease of migration Even faster recovery in the event of disaster Bring data close to your customers Promote to a master for easy migration
  17. 17. Choose cross-region snapshot copy for even greater durability, ease of migration Copy a database snapshot to a different AWS region Warm standby for disaster recovery Base for migration to a different region
  18. 18. How Amazon RDS backups work? Automated backups Restore your database to a point in time Enabled by default Choose a retention period, up to 35 days Manual snapshots Build a new database instance from a snapshot when needed Initiated by you Persist until you delete them Stored in Amazon S3
  19. 19. Monthly bill = + Further details at http://aws.amazon.com/rds/pricing/ Storage consumedDuration for which DB instances were used (Price depends on type of storage) (Price depends on type of DB instance) Free tier (for first 12 months) • 750 micro DB instance hours • 20 GB of DB storage • 20 GB for backups • 10 million I/O operations GBN × You pay for the resources that you use

  21. 21. What is Amazon DynamoDB?
  22. 22. Amazon DynamoDB NoSQL database Fully managed Single-digit millisecond latency Massive and seamless scalability Low cost Amazon DynamoDB
  23. 23. Amazon DynamoDB: a managed document and key-value store Simple and fast to deploy Simple and fast to scale • To millions of IOPS Data is automatically replicated Fast, predictable performance • Backed by SSD storage Secondary indexes offer fast lookups No cost to get started; pay only for what you consume
  24. 24. Popular use cases Ad Tech IoT Gaming Mobile & Web Ad serving, retargeting, ID lookup, user profile management, session- tracking, RTB Tracking state, metadata and readings from millions of devices, real- time notifications Recording game details, leaderboards, session information, usage history, and logs Storing user profiles, session details, personalization settings, entity specific metadata
  25. 25. Writes Replicated continuously to 3 AZs Persisted to disk (custom SSD) Reads Strongly or eventually consistent No latency trade-off Automatic replication for rock-solid durability and availability
  26. 26. Amazon DynamoDB is a schemaless database Table Items Attributes (name- value pairs)
  27. 27. Each item must include a key Hash key (DynamoDB maintains an unordered index)
  28. 28. Each item must include a key Hash key Range key (DynamoDB maintains a sorted index)
  29. 29. Local secondary indexes = alternate range keys Hash key Range key LSI key
  30. 30. Global secondary indexes = “pivot charts” for your table Choose which attributes to project (if any)
  31. 31. Define the desired performance using provisioned throughput Read capacity units Write capacity units 1 RPS > 2.5 M requests in a month
  32. 32. DynamoDB: What are capacity units? One write capacity unit One read capacity unit One strongly consistent read per second up to 4KB or Two eventually consistent reads per second One write per second up to 1KB
