apisix-docker VS aws-lambda-java-libs

This project leverages existing the pre-defined Docker Compose configuration file to set up, deploy, and run APISIX, etcd, Prometheus, and other services with a single command. First, clone the apisix-docker repo on GitHub, open it in your favorite editor, navigate to the example folder, and start the project by simply running docker compose up command in a terminal from the project root folder.

We will leverage the existing file-proxy demo project on GitHub. It has a quite similar structure to the existing Apisix docker example repo, only we removed unnecessary files to keep the demo simple. The project has 3 folders, docker-compose.yml, and sample openapi.yaml files.

git clone https://github.com/apache/apisix-docker.git

This first thing you clone the apisix-docker project repo from GitHub:

Apache APISIX Apache APISIX is an open source, dynamic, real-time, high-performance cloud native API gateway. APISIX provides rich traffic management features such as load balancing, dynamic upstream, canary release, circuit breaking, authentication, observability, and more. Official website https://apisix.apache.org/ GitHub projects APISIX (the core): https://github.com/apache/apisix GitHub - apache/apisix: The Cloud-Native API Gateway GitHub - apache/apisix-dashboard: Dashboard for Apache APISIX GitHub - apache/apisix-website: Apache APISIX Website GitHub - apache/apisix-docker: the docker for Apache APISIX GitHub - apache/apisix-go-plugin-runner: Go Plugin Runner for APISIX GitHub - apache/apisix-java-plugin-runner: APISIX Plugin Runner in Java GitHub - apache/apisix-python-plugin-runner: Apache APISIX Python plugin runner GitHub - apache/apisix-helm-chart: Apache APISIX Helm Chart GitHub - apache/apisix-ingress-controller: ingress controller for K8s

We made use of Apache APISIX docker compose repo where we deployed several components in one run and we demonstrated how the API Gateway can be used to manage sample ASP.NET Core application to retrieve product data using Product microservice's API. Also, you learned how to enable limit-count plugin for the API endpoint. There are many other built-in plugins available in Apache APISIX, you can check them on Plugin Hub page. Basically, APISIX can be a lightweight middleware API Gateway regardless of which programming language, frameworks, tools, or platforms you are developing a microservice or application.

In this demo, we are using Apache APISIX Docker repo and it contains an example docker-compose.yaml file and with other config files that makes straightforward to start APISIX using docker compose. We try out this example:

APISIX uses etcd to save and synchronize configuration. Before installing APISIX, you need to install etcd on your machine. It would be installed automatically if you choose the Apache APISIX Docker compose mode, you will learn more about on the next blog post Use Docker Compose to deploy containerized APISIX to AWS ECS.

The apisix-security-java-spring project makes use of the similar example APISIX docker compose template.

✔️ Create an Azure resource group. ✔️ Configure Azure Container Instances. ✔️ Create a Azure context for Docker to offload Apisix and etcd containers execution to ACI. ✔️ Get Apache APISIX example source code for Docker from GitHub. ✔️ Modify Docker compose file there. ✔️ Setup volumes in Azure Storage Account with Azure File Share. ✔️ Add APISIX config files to Azure File Share. ✔️ Bring up APISIX in Azure Container Instances. ✔️ Verify APISIX running. ✔️ Cleanup after you finish.

In today's world of cloud computing, AWS Lambda is a serverless, event-driven compute service that lets you run code for virtually any type of application or backend service without provisioning or managing servers. You can trigger Lambda from over 200 AWS services and software as a service (SaaS) applications, and only pay for what you use.

The first reason is that serverless architectures are inherently scalable and elastic. They automatically scale up or down based on the incoming workload without requiring manual intervention through serverless compute services like AWS Lambda, Azure Functions, or Google Cloud Functions.

On this day, we both first learned about Lambda. This was the world's first public Functions-as-a-Service platform, better known as FaaS. They told us that this was the next evolution in Cloud Computing. With Lambda, you could now host snippets of code on AWS. There were no more idle workers, and you could auto-scale with minimal additional configuration required. Also, these snippets were event-driven by nature. This was a fully serverless platform.

AWS Lambda simplifies composable applications by offering serverless execution, seamless integration with AWS services, automatic scaling, and cost efficiency without the need to manage servers.

Deploying Dart functions to AWS Lambda enables you to utilize them not only within AWS Lambda but also integrate them with services like Amazon API Gateway, allowing you to leverage them in Flutter applications as well. This unified codebase in Dart offers great convenience.

Event Producers: Generate streams of events, which can be implemented using straightforward microservices with AWS Lambda (for serverless computing), Amazon DynamoDB Streams (to captures changes to DynamoDB tables in real-time), Amazon S3 Event Notifications (Notify when certain events occur in S3 buckets) or AWS Fargate (a serverless compute engine for containers).

Amazon Web Services (AWS) Lambda is a serverless function-as-a-service (FaaS) platform that lets you deploy, run, and scale code in the cloud as self-contained functions without having to manually configure any infrastructure. Lambda runs your functions on demand in response to specific events, such as an HTTP request from the internet or activity in another AWS service.

FaaS is specifically focused on building and running applications as a set of independent functions or microservices. Major cloud providers like AWS (Lambda), Microsoft Azure (Functions), and Google Cloud (Cloud Functions) offer FaaS platforms that allow developers to write and deploy individual functions without managing the underlying infrastructure.

So AWS Lambda is basically a serverless computing service that is offered by AWS. It enables developers to run the code in response to various events. It protects the developers from the pain of managing the servers. Using a serverless execution model helps the developers to handle provision, manage and scale the servers automatically. Through this approach the developers can fully focus on writing the code instead of dealing with other aspects.

The first product that popularized the term “serverless” was AWS Lambda, which is both the prototypical and archetypical function as a service provider. It also has a great name, which pings back to its envisioned place in the cloud of the future. In computer programming, a lambda, often referred to as a lambda function or lambda expression, is a concise way to represent an anonymous function, which is a function without a name. The concept originates from lambda calculus in mathematical logic and has been adopted by many programming languages, each with its own syntax and characteristics.
