Description

This document is a checklist for operators of Terracotta to help with the deployment of Open Terracotta.

1. Capacity Planning

Identify Number of concurrent application requests, writes/reads to clustered object graph (steady-state and peak).
Size of clustered data (planning for disk-size)

2. Failure Analysis

What is the application's target availability SLA ?
What single points of Failure exist in the architecture without Terracotta ?

3. Terracotta Infrastructure Architecture:

Based on Capacity and Availability SLA, size to peak volumes.

TerraCotta Servers
- Number of Terracotta Servers (1 Primary, or 1 Primary with 1/n Hot Stand-By(s)).
- Dedicated Terracotta Servers (and CPU/Memory/Disk Specs) or Co-locate Terracotta Servers with App-Servers.
Choice of Disk Technology
- Sharing: None, SAN, NFS
- Disk RAID Levels
- Disk Size (Based on size of clustered-data, Distributed Garbage Collection settings)
Network Hardening and/or TCP/IP Tuning (if needed)

4. Provision Environments

Incremental provisioning, if environments already exist. Typically:

QA Environment
Stage (and Stress) Environment
Production Environment.

5. Monitoring and Production Processes

Monitor Process and Host Availability (Client JVMs, Terracotta JVMs)
Monitor Network Availability (between a Client JVM and active Terracotta Server)
Monitor Exceptions in Application and Terracotta Server Log Files.
Monitor CPU Utilization on Client and Terracotta Server.
Monitor Terracotta Shared Disk utilization.
Decide, implement suitable Log Rotation Policy and Archival.
Lay out processes around upgrades.
Lay out monitoring Tools/processes (Terracotta Admin Console, http://www.ntop.org for Network Monitoring etc.).
