Course Overview
This training day covers critical design decisions for availability, durability, scalability, archival, and disaster recovery. We also cover techniques for deploying database configuration changes, database version upgrades, and even operating system upgrades without any downtime of the database service.
Prerequisites
This course has the following prerequisites:
- OF100: MongoDB Operations Fundamentals
- OF200: Diagnostics and Performance Tuning
Audience Profile
- Database administrators
Learning Objectives:
On completing this training day, you can evaluate different MongoDB cluster architectures and select an appropriate architecture to meet your production system requirements. You will have the skills to manually manage a cluster and back it up using basic tooling. You will also understand MongoDB concepts relevant to operations, which provides the foundation to explore advanced management tooling in subsequent training days.

Replication: The primary server node copies data onto secondary server nodes. This can help increase data availability and act as a backup if the primary server fails. Sharding: Handles horizontal scaling across servers using a shard key.
To attend the training session, you should have operational Desktops or Laptops with the required specification and a good internet connection to access the labs.
Technical issues are unpredictable and might occur with you as well. Participants must ensure that they have the system with the required configuration and good internet speed to access online labs.
If the problem persists or you face any challenge during the class, you can report it to us or your trainer. In that case, Radiant would provide you with the recorded session of that particular day. However, those recorded sessions are not meant only for personal consumption and NOT for distribution or any commercial use.
Radiant Techlearning offers training programs on weekdays, weekends, and a combination of weekdays and weekends. You can always choose the schedule that best suits your need.
