- Vendor lock-in risks with proprietary tools.
3. Software as a Service (SaaS)
SaaS delivers software applications over the internet eliminating the need for installation or maintenance on local devices.
- Advantages:
- Accessible from any device with internet connectivity.
- No installation or maintenance required.
- Often subscription-based providing cost predictability.
- Disadvantages:
- Limited customization options.
- Data security concerns as information is stored off-site.
4. Function as a Service (FaaS)
FaaS is a serverless computing model that allows developers to run code in response to events without provisioning or managing servers.
- Advantages:
- Cost-effective as you only pay for the function executions.
- Highly scalable and responsive to workload changes.
- Disadvantages:
- Cold start latency issues can affect performance.
- Complexity in managing state and dependencies.
Choosing the right cloud hosting model depends on specific business needs technical expertise and budget considerations. By understanding these models startups can make informed decisions that support their growth and operational efficiency.
