Next-Gen Server Administration & InfraOps
Serverless vs Bare Metal
Serverless removes server management but adds cold starts, vendor limits, and cost surprises. Bare metal gives control and predictable cost but demands operations expertise. The right choice depends on workload shape, team skills, and how predictable traffic is.
Pagrindiniai punktai
- Profile your workload for concurrency, latency sensitivity, and steady-state cost.
- Use serverless for spiky, event-driven, or low-traffic workloads where ops time is scarce.
- Use bare metal or VMs for steady, high-throughput, or latency-critical workloads.
- Measure cold-start impact on user-facing paths before committing to serverless.
- Compare total cost at your actual traffic, not at demo scale.
- Keep data gravity in mind: compute follows storage for cost and latency.
- Avoid lock-in by keeping business logic portable across runtimes.
- Re-evaluate the decision as traffic and team size change.
Dažniausiai užduodami klausimai
Is serverless always cheaper?
No. At steady high traffic, provisioned capacity often wins on cost.
Can I mix both?
Yes. Many estates run APIs on serverless and databases or batch jobs on provisioned hosts.
What about compliance?
Data residency and audit requirements can rule out some serverless platforms.
How do I avoid vendor lock-in?
Keep handlers thin, use standard HTTP and events, and abstract storage access.
