Why Some Developers Love Serverless So Much?

Serverless is still new and there are a lot of developers who do not understand what is behind the name and ask questions like Serverless Functions vs Microservices. Serverless is a pricing model. Serverless introduces an additional abstraction layer. Cloud made many thing a lot simpler. A single developer can easily spin up a virtual machine withinf a few minutes. PaaS, Serverless are extending the scope of IaaS. In serverless, instead of virtual servers, we have an entire server room ready to run our code. We hardly have to think about scalability. Many developers do not want to think about managing servers or container orchestration. Rater they think about microservice architecture. Not all developers love Serverless. Not all are complete blind fan of the current implementations – most divide apps like testing. Serverless is essentially the next step in cloud computing.

Serverless allows small teams to build applications faster while they can focus on the product. They need need to effort spent effort behind infrastructure. Usually front end and full stack developers love using serverless faster. In many use-cases, the front end developer need to deploy production-ready backend coding, like for WordPress theme designing or CodePen like website. Serverless is about giving developers the ability to execute code without requiring any sysadmin.

The functions we write come with preconfigured bindings to other services. Which means we need to write lesser code. Microservice users usually are serverless users. As the functions are usually stateless, we sometimes need to think about how to handle state. With serverless, we o obviously loss the fine-grained control of the actual servers, but our use-cases are often of not that scale to fear or we have some fall back ready. It is like running a snippet. It is more practical in the field of IoT prototyping – Arduino compatible boards does made works easy. ESP32 no way far away from production grade board. We can summarize the points to like Serverless as some points :

1. No server management
2. Automated high availability
3. Flexible scaling
4. No idle capacity
5. No need to think of provisioning and utilization
6. Zero operations and management
7. No headache of availability
8. Fault tolerance
