a9s MySQL for PCF
WARNING: The a9s MySQL for Pivotal Cloud Foundry (PCF) tile is currently in beta and is intended for evaluation and test purposes only. Do not use this product in a PCF production environment.
This documentation describes the a9s MySQL for Pivotal Cloud Foundry (PCF) tile. a9s MySQL for PCF enables on-demand provisioning of VM-based dedicated MySQL servers and clusters. Developers can create clustered and single node MySQL service instances, using Apps Manager or the Cloud Foundry Command Line Interface, and bind them to apps. A service instance may be associated with a single dedicated VM or a cluster spread across multiple VMs. You can choose between single VM and clustered MySQL services instances with service plans.
When you run the cf CLI
create-service a9s-MySQL command, PCF creates dedicated VMs for this service instance. This provides protection from bad neighbors.
MySQL service instance provisioning, including VM orchestration, is entirely automated. This enables service instances to be highly isolated and shielded by infrastructure virtualization mechanisms.
Due to the on-demand provisioning on VMs, only existing service instances allocate infrastructure resources. These resources are released when service instances are destroyed. Using on-demand, provisioning the number of service instances is not limited by design.
Distributed across multiple infrastructure availability zones, clustered data service plans enable short failover times and are resilient against failures of individual infrastructure hosts or entire availability zones.
a9s MySQL for PCF includes the following key features:
|On-Demand Service Instance Provisioning||a9s MySQL for PCF deploys MySQL instances automatically. Developers can provision a single-VM MySQL server using a single command.|
|Service Instance Isolation||Each MySQL server runs on a dedicated VM to ensure bad neighborhood protection in order to be aligned with enterprise security requirements.
a9s MySQL for PCF uses Cloud Foundry security groups to prevent network connections being established by unauthorized apps.
|Smoke Tests||a9s MySQL for PCF contains a post-deploy smoke tests errand that runs a series of basic tests against your installation to ensure that it is configured properly.|
|Service Instance Capacity Upgrade||Cloud Foundry Service Plan updates allow upgrades to the RAM, CPU, and storage capacity for your MySQL instances.|
|Logging and Monitoring||Each MySQL service instance provides log messages and MySQL-specific metrics to one or more
|Deployment Updater||This errand automatically updates the stemcell and all provisioned a9s MySQL for PCF service instances to their lastest version.|
|Service Guard||The Service Guard creates Cloud Foundry security groups for your service instance VMs.
When the IP address of a service instance changes, the guard updates the security group. The Service Guard also restarts the application instances bound to the affected service instance. The instances of one app are restarted one by one to avoid downtime.
|High Availability||a9s MySQL for PCF ensures high availability.
The Consul-based internal DNS system provided by a9s Consul DNS for PCF ensures that the connected application always connects to a working node.
|Service Dashboard||The Service Dashboard provides single sign on and lets the user easily trigger backups.|
|Syslog Endpoints for Instances||In the tile, a default endpoint for syslog and Graphite can be configured for each service instances which is greated by the end user.|
