Dealing with infrastructure entails various tasks. For example, upgrading operating systems, applying security patches, and executing regular maintenance of physical connections. In a company, such tasks are carried out by different people who have expertise in each case. Having these roles in a company also implies that the company has to spend some money, and probably a large chunk of their budget, on these types of tasks. Apart from that, maintenance tasks may involve some risk due to problems or human mistakes. In this lesson, you’ll learn the alternative solution that companies deploy to avoid spending money on maintenance.

Understanding serverless computing

With the advent of cloud computing, many possibilities opened up. One of those was serverless computing.

Serverless is a type of service that cloud providers offer, through which companies only have to deploy their code and have any type of maintenance, scalability, and infrastructure validation taken care of for them.

Serverless belongs to Platform as a Service (PaaS). A cloud provider will support the load that the company can have at some point by adding more capacity automatically. On the other hand, when the load is low and the computing capacity is high, the cloud provider will reduce that capacity automatically. It is worth mentioning that this process is done by the cloud provider and companies don’t have to configure anything.
