What is AWS Serverless ?

Serverless is the local design of the cloud that empowers you to move a greater amount of your operational obligations to AWS, expanding your dexterity and advancement. Serverless enables you to construct and run applications and administrations without contemplating servers.

It eliminates infrastructure management tasks such as

  • Server or cluster provisioning
  • Patching
  • Operating system maintenance
  • Capacity provisioning

You can assemble them for about an application or backend administration, and everything required to run and scale your application with high accessibility is taken care of for you.

Why use serverless ?

Serverless enables you to build modern applications with increased agility and lower total cost of ownership. Building serverless applications implies that your developers can concentrate on their center item as opposed to stressing over overseeing and working servers or runtimes, either in the cloud or on-premises. This reduced overhead lets developers reclaim time and energy that can be spent on developing great products which scale and that are reliable.

What are the benefits of serverless ?

  • No server management
    • There is no need to provision or maintain any servers. There is no software or runtime to install, maintain, or administer
  • Flexible scaling
    • Your application can be scaled automatically or by adjusting its capacity through toggling the units of consumption (e.g. throughput, memory) rather than units of individual servers.
  • Pay for value
    • Pay for consistent throughput or execution duration rather than by server unit.
  • Automated high availability
    • Serverless provides built-in availability and fault tolerance. You don’t need to architect for these capabilities since the services running the application provide them by default.
