What is “Serverless”?

serverless technologies

In some cases, serverless is wrongly related to a context in which a server does not exist. However, a server does exist, but no management tasks on a server will be performed; its maintenance and execution is be done by a vendor.

In other words, having a “serverless” architecture involves avoiding server management and as any other cloud resource, you only pay for what you use.

The most important benefits of leveraging a serverless infrastructure are:

  • Ease of deployment.
  • Flexible and quick to deploy and does not generate long-term commitments.
  • Cost-effective because idle resources do not cause any additional cost.
  • Friendly since it gets along with micro services.
  • It will decrease the time to get into the market, helping the software to be launched faster.

Nevertheless, not all that glitters is gold talking about going serverless. There are some challenges that might prevent its adoption.

These are some of them:

  • Lack of tools because developers depend on vendors for debugging and monitoring of tools.
  • Complex architecture since it gets difficult to manage too many functions.
  • Integration and “serverless” applications are complex.


Serverless is an innovative and growing technology. Therefore, many companies are benefiting from it since they avoid spending resources on servers’ management while helping them to keep the focus on what drives money to the business
