Frequently Asked Questions
What is serverless computing?
Serverless computing platforms allow developers to build and run applications and services without managing servers. This means you don't have to provision, scale, or manage any underlying infrastructure. You simply write your code and the platform handles the rest, automatically scaling resources as needed.
What are the advantages of using a serverless platform?
The primary benefits include reduced operational costs (pay-per-use pricing), faster development cycles, automatic scaling, and increased developer productivity. You can focus on writing code instead of server administration.
What are the potential drawbacks of serverless computing?
Vendor lock-in, cold starts (latency when functions are invoked after a period of inactivity), debugging complexity, and limitations on execution time and memory are some common challenges.
How are serverless platforms typically priced?
Pricing models vary, but most serverless platforms use a pay-per-use model. You're typically charged for the number of requests, the duration of execution, and the amount of memory consumed. Some platforms may also have free tiers or generous free allowances to attract new users.
What factors should I consider when choosing a serverless platform?
Key considerations include: Functionality (supported languages, integrations), Scalability and Performance, Pricing, Community and support. Vendor lock-in is also an important factor to keep in mind.
