The advent of serverless computing has transformed the conventional approach to application development and deployment. This model, where the allocation and provisioning of servers occur dynamically by the cloud provider, offers unique benefits. It allows for a focus on application functionality, eliminating the need for users to manage servers. Let’s dive into the definition, benefits, and services created by serverless computing.
What is serverless computing?
In the realm of cloud computing, serverless computing stands as a model where the cloud provider dynamically manages the allocation and provisioning of servers. The intriguing part? Users need not worry about server management – they focus solely on their applications’ functionality. To summarize, serverless computing allows developers to create applications without having to worry about server management.
Services offered by serverless computing
There are a plethora of services that serverless computing brings to the table:
-
Function as a Service (FaaS)
This is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage application functionalities without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.
-
Backend as a Service (BaaS)
For Backend as a Service (BaaS), which is different from Backup as a Service (BaaS), the backend services are provided by the serverless providers. These services can include user authentication, database management, push notifications, and social media integrations, making it easier for developers to focus on the user interface and user experience.
-
Database as a Service (DBaaS)
Here, the cloud service provider takes care of all the hassles of database maintenance and scalability. This allows developers to focus on their data and not worry about database management.
Benefits of serverless computing
Serverless computing comes with a host of benefits:
-
Cost efficiency
With serverless computing, there’s no need to pay for idle computing resources. Costs are based on actual consumption, not on pre-purchased capacity.
-
Scalability
Serverless architectures can automatically scale to accommodate traffic patterns – from a few requests per day to thousands per second.
-
Reduced operational complexity
It eliminates the need for system administration. The cloud provider handles everything, allowing developers to focus on the code.
-
Faster time to market
Serverless computing can significantly speed up software and feature releases because developers can focus on coding rather than managing and operating servers.
Other cloud backend models
While serverless computing has its charm, there are other cloud backend models worth mentioning:
-
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet. It’s an instant computing infrastructure, provisioned and managed over the internet.
-
Platform as a Service (PaaS)
PaaS is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.
Final thoughts
Serverless computing is a dynamic and cost-effective model that offers a multitude of benefits. It allows developers to focus more on the application functionality and less on server management. While it’s not the only cloud backend model available, it has certainly carved out a unique niche in the cloud computing landscape.
