3 Agenda Using MySQL in the Cloud Benefits Cloud Computing Improvements in version 5.6 Best Practices General MySQL in the Cloud Performance Suggestions Using MySQL with Amazon Web Services Summary

4 Using MySQL in the Cloud Where s the magic? Nothing special about MySQL in the cloud (in general) Full features available Same tools to manage and monitor So what is different? Rapid deployment Rapid scale out High Availability at lower costs

5 Benefits of using MySQL in the Cloud MySQL is the default database for the Web MySQL is available in many cloud solutions MySQL is the leading database by far in the cloud today MySQL 5.6 (and Cluster 7.2) features influenced heavily by demand from cloud implementers and users alike Don t take my word for it evaluate 5.6 yourself.

6 MySQL Is Ubiquitous In The Cloud Hosting SaaS IaaS, PaaS, DaaS

7 MySQL 5.6 Improvements InnoDB Full Text Search Larger REDO logs UNDO logs in own tablespace Pre-warming Buffer Pool Improved auto-extension for.ibd files Page size 4k -> 64k

8 MySQL 5.6 Improvements Replication Optimized Row-based Replication Binlog API Remote Binlog Backup Binlog Group Commit Durable Slave Reads Enhanced Multi-threaded Slaves and much more! As MySQL improves so does its viability for cloud services

9 MySQL Cloud Computing - General Make a plan for using your cloud resources. Design for failure Make a disaster recovery plan Be vigilant! Use good security practices. Protect data to/from the cloud Protect access mechanisms Don t think I don t need to backup. My provider does that. Don't forget monitoring You can and should monitor your MySQL servers running in the cloud.

10 MySQL Cloud Computing - Performance Warm up data partitions You can use the Linux dd command to write to the disk. While the penalty still occurs and cannot be avoided, at least the first write to your databases will not suffer the effects. Use MySQL replication MySQL replication is for scale out, load balancing, and high availability. The cloud makes these features easier to use.

11 MySQL Cloud Computing - Performance Use partitioning to divide your data over smaller instances Dividing the data can save on resources as well as improve performance Know your access patterns Design your database for optimal performance Commit to using only those resources needed Mount partitions with noatime or nodiratime options Mounting your partitions with either of these options should yield up to 10% better I/O performance

12 MySQL Cloud Computing - AWS Run only one MySQL Server per EC2 instance MySQL will run faster with dedicated computational units and memory resources. Leverage larger instance types for heavy usage You should consider using larger instance types for high transactional or heavy read or write databases. Use additional EBS volumes for InnoDB tablespaces Use multiple EBS volumes to separate your databases and use multiple InnoDB tablespaces (e.g., one per EBS volume) to get better I/O performance.

13 MySQL Cloud Computing - AWS Use EBS with MySQL EBS is a block store device with good performance and sustainability from instance failures, as well as elasticity. Perform snapshotting Using S3 Snapshots are an effective and efficient way to take a backup and provide a mechanism for rapid recovery in the event that data becomes corrupt. Use load balancing You can use the Amazon Elastic Load Balancing resource or even run your own software load balancer such as HAProxy.

14 MySQL Cloud Computing - AWS Use standard AMIs Unless you have vast experience in running the host operating system in a virtual environment, the task of building custom AMIs can be time consuming and error prone. Whenever possible, use the existing Amazon AMIs or known stable community AMIs. Be sure to configure MySQL properly Simply running MySQL in EC2 isn't going to make it faster.

15 Summary MySQL runs great in the cloud Plan and execute your use of MySQL in the cloud with the same attention to detail as if running on real hardware Design for High Availability Manage your resources
