This cloud computing model has become increasingly popular over the past few years as a way to develop and deploy applications. It allows developers to focus on writing code and building instead of worrying about servers, operating systems, and other infrastructure-related tasks.
However, like any other technology, serverless architecture has its pros and cons. We'll discuss both in this article, as well as explain what it is in greater detail.

Understanding Serverless Architecture
definition. Serverless Architecture is a cloud computing model where providers dynamically manage the allocation of computing resources.
*The term "serverless" is actually a bit of a misnomer: Servers are still involved in the process, but the cloud provider manages the servers and resources, freeing the developer from that responsibility.
The cloud provider takes care of the underlying infrastructure and provides an environment where developers can run their applications without managing servers, virtual machines, or operating systems. Developers write functions that perform specific tasks, and these functions are executed by the cloud provider in response to specific triggers or events.
Examples of serverless architecture include AWS Lambda, Azure Functions, and Google Cloud Functions. In each, developers write functions that perform specific tasks, and the cloud provider takes care of the underlying infrastructure, allowing developers to focus solely on writing code for their applications. This approach has many benefits, but also some potential setbacks to consider:
Pros
1. Cost-Effective
Serverless architecture eliminates the need for maintaining servers and other infrastructure. Instead, you only pay for the resources you consume, such as function, execution, time, and memory usage.
2. Scalability
This approach allows you to easily scale your applications up or down based on demand; You can easily handle spikes in traffic without having to worry about provisioning additional resources.
3. Reduced Management Overhead
With serverless architecture, you don't have to worry about server maintenance, operating system upgrades, and other infrastructure-related tasks. Instead, you can focus on developing and deploying applications without the need for additional management overhead.
4. Faster Development
Without worrying about infrastructure, you can write code faster and deploy applications quicker.
Cons
1. Limited Control
You can't customize the infrastructure to meet some specific requirements.
2. Cold Starts
These can occur when a function is triggered for the first time, resulting in a longer response time. This can be a problem for applications that require real-time responses, like chat bots, online gaming, financial trading, video conferencing, or live streaming.
3. Vendor Lock-In
Serverless architecture relies on cloud providers to manage infrastructure. However, this means that you are tied to the cloud provider's services and APIs, making it difficult to switch providers if necessary. Consider whether you may need to change your cloud provider service or API in the future; You may need to due to cost, security, or performance capabilities as your application grows and evolves.
4. Debugging
It may be difficult to troubleshoot issues since you don't have direct access to the infrastructure.
Serverless architecture has many benefits, but make sure to weigh the pros and cons before deciding to use it for your application.
