Study Notes

Serverless Architecture vs Traditional Server-Based Architecture

Serverless Architecture:
- Definition: The cloud provider dynamically manages server allocation and provisioning. Developers focus on code, not infrastructure.
- Characteristics:
  - Dynamic Scaling: Automatically adjusts resources based on demand.
  - Billing Model: Costs are based on actual usage (function executions or time).
  - Stateless: Functions are independent and executed in response to events (e.g., image uploads).
  - Example: Photo sharing applications where backend tasks (resizing images, processing metadata) are handled by serverless functions.
- Pros:
  - Reduced Operational Overhead: No server management needed.
Traditional Server-Based Architecture:
- Definition: Applications are deployed, maintained, and scaled by the developer or operations team on dedicated servers.
- Characteristics:
  - Fixed Resources: Servers have predefined resources that need manual scaling.
  - Continuous Operation: Servers run continuously, regardless of demand.
  - Billing Model: Typically ongoing costs regardless of usage (including maintenance).
  - Example: Company websites hosted on dedicated servers or shared hosting services.
- Pros:
  - Full Control: Complete control over server environment and infrastructure.
  - Flexibility: More flexibility in configuring and optimizing the server.
- Cons:
  - Higher Costs: Costs for unused server capacity and continuous maintenance.
  - Operational Complexity: Requires active management of the server infrastructure.
  - Limited Control: Limited control over the environment and underlying infrastructure.
  - Cold Starts: Potential latency issues when initializing a function.
  - High Scalability: May require manual scaling to accommodate peak loads.

Key Differences

Infrastructure Management: Serverless abstracts away server management; traditional requires active management.
Scaling: Serverless automatically scales with demand; traditional requires manual adjustments.
Cost Model: Serverless is a pay-as-you-go model; traditional involves ongoing costs.

Conclusion

Serverless architecture is ideal for applications with variable workloads where simplifying management and reducing costs is prioritized.
Traditional server-based architecture is suitable for applications requiring extensive control over the environment and predictable performance.
Choosing the right architecture depends on application needs, workload patterns, and operational preferences.
