What is the serverless ecosystem?
The serverless ecosystem has revolutionized technological development by allowing us to deploy applications without having to manage the infrastructure. But what does it really mean? In a serverless environment, concerns about server, memory or CPU configuration are eliminated, since applications run on a specific runtime that is not directly managed by the developer. This makes it easier to focus solely on developing functions with languages such as Python or JavaScript.
What is the relationship between client and server?
Traditionally, the client-server scheme involved detailed configurations for both sides. The client can be a backend or frontend application that communicates with the server through protocols such as TCP. In serverless scenarios, these configurations include the server's operating system, RAM and CPU. The crucial difference is that in serverless, these administrative tasks are taken over by the cloud service provider, which simplifies the operation.
What is the cloud and who are the main cloud providers?
When we talk about "the cloud", we are referring to a remote infrastructure composed of multiple servers that provide various services such as computation and storage. Cloud providers are companies that offer access to this infrastructure. Among the most prominent are Amazon Web Services (AWS), Google Cloud Platform (GCP) and Microsoft Azure. These providers not only provide basic services, but also a wide range of serverless options.
What does AWS offer as a Cloud Provider?
AWS is one of the leaders in cloud services, offering a multitude of options such as compute, storage, and data management, all accessible through a user-friendly and cost-competitive interface. AWS stands out for its comprehensive approach to the serverless ecosystem, providing tools such as AWS Lambda, AWS Fargate and Step Functions that enable the development of scalable and efficient applications.
How does AWS compare to other Cloud Providers?
Although AWS dominates the market, GCP and Azure offer similar features. Each provider has its own advantages and specialized serverless services. Google Cloud, for example, is known for its artificial intelligence tools, while Azure effectively integrates Microsoft services. Still, each of these providers allows you to generate robust and scalable applications without needing your own physical infrastructure.
What is the Serverless Framework and how does it differ from Serverless?
While the term "serverless" refers to the general paradigm where the infrastructure is managed by a provider, the Serverless Framework is a specific tool that optimizes the development process in this environment. This framework enables more efficiency through the use of the serverless.yaml file, where the resources and functions required to develop on AWS are clearly defined.
How does the Serverless Framework facilitate development?
The Serverless Framework allows infrastructure with code that facilitates greater control over the development environment and the integration of custom functions. In addition, it aligns with the concept of Infrastructure as Code (IaC), similar to tools such as Terraform, CDK or Pulumi, although simplifying many of these tasks.
What are the advantages of the Serverless Framework?
By seamlessly integrating with AWS, Serverless Framework simplifies resource management in this environment through clear and well-structured YAML templates. In addition, it offers support for incorporating external systems and managing infrastructure without leaving the serverless framework. This tool promotes an agile and optimized development flow, reducing the operational burden.
With the adoption of serverless and the use of the Serverless Framework, the main focus is on code and functionality, without the typical burdens of server management and configuration, making applications more agile and easier to scale.
