[Unpopular Opinion] Serverless computing is overrated.

If you are a software engineer, you'll undoubtedly come across the term "serverless computing." While it may seem like a revolutionary concept at first, I'd like to share my opinion that it might not be as impressive.

Let's take a critical look at the limitations of serverless.

  • At its core, serverless is a model of cloud computing that allows developers to write and deploy code without having to manage or provision any servers. However, there are a few key issues with this model that are often overlooked.
  • First, serverless is not actually serverless – it just means that you're outsourcing server management to a third-party provider. This means that you're at the mercy of the provider's performance, pricing, and limitations. You also lose control over the entire stack, which can be a problem when trying to debug or optimize your system.
  • Another issue with serverless computing is that it's not always the most cost-effective solution. While it can be cheaper than running your own servers in some cases, it can also become more expensive as your usage scales up.
  • Moreover, serverless computing can also introduce latency and performance issues, especially when dealing with "cold starts". Since the FaaS platform needs to spin up a new instance of a function every time it's called, there can be a noticeable delay in response time if the function hasn't been called in a while.
  • The event-driven model of serverless computing can be challenging to work with. It requires a different way of thinking about application design and development, and can often result in more complex and harder to maintain code.

    In conclusion, it's important to weigh the pros and cons and choose the cloud computing model that best suits your specific needs. Serverless computing can be useful in some situations, but it's definitely not a silver bullet!
