Going forward we’re going to discuss the 5 best serverless frameworks in 2022 by their features, advantages, disadvantages, pricing, and use case. Choosing the correct serverless platform plays an important role in your project’s success early on. One must compare all the best options available to choose a platform that best fits the product’s needs, size, scaling ambition, and team size.
What is a Serverless Platform?
A serverless platform takes care of software functionality and communication by using a combination of computing containers. The available computational power fluctuates based on user activity – if the app is actively operating, it utilizes more containers, and if it isn't, it uses less. Some of the main features of a serverless platform are-
A serverless platform lets you focus entirely on the primary user-side functionality. The user isn’t aware of anything about the server on which their program is running, and a third-party vendor handles all the details about the operating systems and updates.
Serverless solutions enable business owners to control the number of computing resources that are consumed. A user does not have to overpay for excessive server space in case of small workloads. Furthermore, if a user needs an increase in computing power, the platform is readily available with the resources.
A user does not have to pay when their application isn’t active which directly leads to cost reduction.
Adopting a serverless approach is one of the best ways to increase product scalability and optimize the costs of backend operations. However, one must choose the correct vendor that takes full responsibility for server performance and gives you full power to monitor your serverless application. Here’s the list of our top 5 serverless platforms to help you make a well-informed decision-
1. AWS Lambda
AWS Lambda is a serverless computing service by AWS that monitors lambda functions. It allows users to write codes and execute them unfailingly, without having to worry about the infrastructure or managing the servers. The developers get the authority to use Amazon CloudWatch to report metrics after executing the functions. AWS Lambda is the most suitable option when it comes to building applications using Python, Java, Node.js, C#, Go, and Ruby.
- Using AWS Lambda you easily compute the data as it enters or moves through the cloud by adding custom logic to AWS resources such as Amazon DynamoDB tables and Amazon S3 buckets.
- AWS Lambda allows you to customize your backend services as per your business needs. For example, you can use the Lambda API to trigger new backend application services on-demand or use Amazon API Gateway to build custom API endpoints.
- One does not need to learn any new languages, frameworks, or tools to use AWS Lambda.
- AWS Lambda functions as a completely automated administration.
- It has a built-in fault-tolerance system. It protects your code from data center facility or individual machine failures by maintaining compute capacity across multiple Availability Zones (AZs) in each AWS region.
- Free Version: It supports 1 million requests in 400,000 seconds per month.
- Premium version: It is priced on the basis of per-request($0.20 for 1 million requests) and per-second(0.000016667 for 1 GB per second).
- It allows you to pay for what you use. It offers a flexible pricing strategy that depends entirely on your app’s performance, and not on the duration of your subscription.
- It has one of the most versatile development environments that manage infrastructure on your behalf. It has tools for AI, databases, IoT, cloud, and blockchain development.
