2. Basics of Cloud Anomaly Detection
2.1 Defining Anomalies in Cloud Computing
Anomalies in cloud computing are odd events that differ from normal system behavior. These can include:
- Sudden jumps in resource use (CPU, memory, network)
- Strange network traffic patterns
- Quick drops in how well the system works
- Attempts to access without permission
It's important to tell the difference between normal changes and real problems. For example, a short increase in CPU use isn't always a problem if other parts of the system are working fine.
2.2 Main Types of Anomalies
Cloud computing anomalies fall into three main groups:
Type | What it means | Example |
---|---|---|
Performance | System suddenly works worse | Service takes longer to respond |
Security | Odd activities that might be threats | Someone tries to log in without permission |
Resource | Unexpected changes in resource use | Memory use suddenly goes up a lot |
Knowing these types helps create better ways to spot and fix problems.
2.3 Cloud Parts Most Affected by Anomalies
Anomalies can cause issues in different parts of cloud systems:
Cloud Component | Possible Issues |
---|---|
Virtual Machines | Work poorly, shut down unexpectedly |
Network | Odd traffic patterns, attacks that flood the system |
