• Fastest growing with over 70,000 downloads per day

• Under active development since 1995

MySQL is installed across every continent in the world.(Yes, even Antarctica!)



MySQL Cluster Carrier Grade Edition• Most secure, scalable MySQL database, development /

management / monitoring tools, backed by Oracle Premier Lifetime Support



MySQL Cluster Users and Applications



• What are the consequences of down time or failing to meet performance requirements?

• How much effort and money is spent in developing and managing high availability in your applications?

• Are you considering sharding your database to scale write performance? How does that impact your application and developers?

• Do your services need to be real time?

• Will your services have unpredictable scalability demands, especially for writes?

• Do you want the flexibility to manage your data with more than just SQL?

Key Questions to Ask When Considering MySQL Cluster

How Does the MySQL Cluster Manager Help?

Before MySQL Cluster Manager• 1 x preliminary check of cluster state• 8 x ssh commands per server• 8 x per-process stop commands• 4 x scp of configuration files (2 x

mgmd & 2 x mysqld)• 8 x per-process start commands• 8 x checks for started and re-joined

processes• 8 x process completion verifications• 1 x verify completion of the whole

cluster • Excludes manual editing of each

configuration fileTotal: 46 commands - 2.5 hours of attended operation

With MySQL Cluster Manager

upgrade cluster --package=7.1 mycluster;

Total: 1 Command - Unattended Operation

Results• Reduces the overhead and

complexity of managing database clusters

• Reduces the risk of down time resulting from administrator error

• Automates best practices in database cluster management

Example: Initiating upgrade from MySQL Cluster 7.0 to 7.2



If You Are Not Using the MySQL Cluster Manager

• You can perform tasks manually, but you have to:o Issue many commandso Be present while the process is running

• You can script operations, but:o Writing scripts takes timeo You need to assign time to test and

maintain scriptso Scripts add risk and complexity to the

system



MySQL Tools• Graphical and command-line interfaces to your

MySQL databases• MySQL Enterprise Monitor

o Web application that reduces down time, tightens security, and increases throughput

o Includes MySQL Query Analyzer

• MySQL Enterprise Backup• Online “Hot,” non blocking backups• MySQL Workbench

o Visual database design tool that is used to efficiently design, manage, and document databases
