Course Outline
Module 1: Introduction and MongoDB Architecture (4h)
Content:
- History and the MongoDB ecosystem.
- Typical use cases, pros, and cons.
- General architecture: instances, processes, and configuration.
Practice:
- Interactive exploration: connecting via Mongo Shell/CLI.
- Creating a sample database and collection.
Module 2: Installation and Initial Configuration (6h)
Content:
- Hardware and resource requirements.
- Installation on Linux (deb/rpm), Windows, and macOS.
- YAML configuration files (mongod.conf): dataDir, logDir, bindIp, port.
- Startup options and systemd/service management.
Practice:
- Deploying instances on local VMs or Docker containers.
- Adjusting configurations for development versus production environments.
- Verifying secure remote connectivity.
Module 3: Data Modeling and Basic Operations (5h)
Content:
- BSON documents, collections, and databases.
- Modeling: embedding vs. referencing; data design patterns.
- Basic indexes (introduced earlier).
- Operations using Mongo Shell and scripting examples with drivers.
Practice:
- Modeling a use case: such as an inventory or billing system.
- Implementing CRUD operations.
- Schema validation using JSON Schema in MongoDB.
Module 4: Indexes and Performance (4h)
Content:
- Simple, compound, multikey, text, and geospatial indexes.
- Using explain() and analyzing metrics.
- Impact of indexes on write performance and memory usage.
Practice:
- Creating collections with test data.
- Testing queries with and without indexes; interpreting explain() output.
- Adjusting indexes based on access patterns.
Module 5: Security (5h)
Content:
- Authentication mechanisms: SCRAM, LDAP/Kerberos (intro).
- Defining users and custom roles.
- TLS/SSL between clients and servers.
- At-rest encryption: key configuration.
- Basic audit logging.
Practice:
- Creating users with minimal privileges.
- Configuring TLS in local instances.
- Verifying unauthorized access and reviewing audit logs.
Module 6: Replication and High Availability (6h)
Content:
- Replication concepts: Primary, Secondary, oplog.
- Replica set configuration: initiation, membership, arbitration.
- Monitoring status and elections.
- Maintenance: adding/removing members, reassigning priorities.
Practice:
- Deploying a three-node replica set (local or VMs).
- Simulating primary failure and observing failover.
- Rebuilding secondary nodes and recovering replicas.
Module 7: Sharding and Horizontal Scalability (6h)
Content:
- Sharding concepts: shard key, config servers, mongos router.
- Shard key selection and associated risks.
- Deploying config servers, shards, and mongos.
- Rebalancing and chunk migration.
Practice:
- Configuring a simple sharded cluster.
- Inserting large-scale data and observing distribution.
- Introducing shard key changes and understanding limitations.
Module 8: Backup, Restore, and Disaster Recovery (4h)
Content:
- Native tools: mongodump/mongorestore, filesystem snapshots.
- Backups in replica sets and sharded clusters.
- Basic use of Cloud Manager/Ops Manager for backup.
- Disaster Recovery (DR) planning: RTO, RPO.
Practice:
- Performing backup and restore on a test database.
- Simulating failure and recovery from backup.
- Designing a DR plan for a hypothetical case.
Module 9: Monitoring and Alerts (4h)
Content:
- Tools: mongostat, mongotop, Cloud Manager/Atlas Monitoring.
- Integration with Prometheus + Grafana (concepts and examples).
- Key metrics: CPU, memory, I/O, oplog size, latencies.
- Alerts: defining thresholds and notifications.
Practice:
- Deploying a local or container-based monitoring agent.
- Setting up basic dashboards with sample metrics.
- Simulating load and observing alerts.
Module 10: Maintenance, Upgrades, and Best Practices (4h)
Content:
- Upgrade strategies for replica sets and sharded clusters.
- Data cleanup, compaction, integrity checks.
- Reviewing logs and regular audits.
- Automating routine tasks (scripts, cronjobs, Ansible, Terraform).
- Data retention and archiving policies.
Practice:
- Simulating minor and major upgrades in a controlled environment.
- Creating automation scripts for backup and monitoring.
- Developing a periodic maintenance checklist.
