Moving to Managed Databases

Sohan Maheshwar Developer Advocate, AWS

Why move to managed services?

Managed database services

Flexible ways to move to AWS databases

Resources

Q&A

Hardware and software installation, configuration, patching, backups

Performance and high availability issues

Capacity planning and scaling clusters for compute and storage

Security and compliance

Self-managed Fully managed Schema design Query construction You Query optimization Automatic failover Backup and recovery Isolation and security You Industry compliance Push-button scaling AWS Automated patching Advanced monitoring Routine maintenance Built-in best practices

Solution They moved from self-managed MySQL to Amazon Aurora MySQL. They use Aurora as the primary transactional database, Amazon DynamoDB for personalized search, and Amazon ElastiCache as in- memory store for sub-millisecond site rendering.

Result Initially, the appeal of AWS was the ease of managing and “customizing the stack. It was great to be able to ramp up more servers without having to contact anyone and without having minimum usage commitments. AWS is the easy answer for any Internet business that wants to scale to the next level. —Nathan Blecharczyk, Cofounder and CTO of Airbnb ”

PostgreSQL

Easy to administer Performant & scalable Available & durable Secure and compliant

Easily deploy and maintain Scale compute Automatic Multi-AZ data Data encryption at rest and in hardware, OS and DB and storage with a few clicks; replication; automated transit; industry compliance software; built-in monitoring minimal downtime for your backup, snapshots, and and assurance programs application failover

MySQL and PostgreSQL-compatible relational database built for the cloud Performance and availability of commercial-grade databases at 1/10th the cost

Performance Availability Highly secure Fully managed and scalability and durability

5x throughput of standard MySQL Fault-tolerant, self-healing storage; Network isolation, Managed by RDS: and 3x of standard PostgreSQL; six copies of data encryption at rest/transit, No server provisioning, software scale-out up to across three Availability Zones; compliance and assurance patching, setup, configuration, or 15 read replicas continuous backup to Amazon S3 programs backups

Challenge Building and maintaining a production database on PostgreSQL was challenging for a fast-growing startup.

Solution The company turned to AWS to run its database on Amazon RDS for PostgreSQL.

Result The company can now add millions of new items to its database every month, allowing engineering to improve the customer experience.

Millions of requests per second, Same code, drivers, and tools you Simple and millisecond latency use with MongoDB fully managed

Secure and 2x throughput of managed Deeply integrated compliant MongoDB services with AWS services

Fully compatible with In-memory data store AWS manages all hardware Scale writes and open source Redis and cache for microsecond and software setup, reads with sharding and Memcached response times configuration, monitoring and replicas

Solution: They moved from self managed Redis to fully managed Amazon ElastiCache for Redis as a caching layer on RDS for MySQL

Result: ElastiCache provides sub-millisecond latency even in times of peak traffic of hundreds of thousands of cab requests per minute
