Course Overview:
This course covers everything a database administrator needs to know to successfully deploy and maintain MongoDB databases.
Course Objectives:
- Understand MongoDB from a developer’s perspective, including its command shell, query API, and driver tools.
- Deploy MongoDB in all its configurations – as a single server, with master/slave replication, as a replica set, and as a sharded cluster.
- Evaluate applications and choose hardware appropriately.
- Monitor MongoDB instances and integrate with standard monitoring software (Munin, Nagios, etc.)
- Plan for backups and manage large data imports and exports.
- Troubleshoot the most common developer issues and failure scenarios.
- Each delegate will need to perform a series of practical exercises.
Pre-requisites:
- Web and Java Application developer
Target Audience:
- A Basic knowledge of core java
- Experience with any other web framework will be helpful
Course Duration:
- 21 hours – 3 days
