With various access control models and implementation methods available, constructing an authorization system for backend service APIs can still be challenging. However, the ultimate goal is to ensure that the correct individual has appropriate access to the relevant resource. In this article, we will discuss how to enable the Role-based access control(RBAC) authorization model for your API with open-source API Gateway Apache APISIX and Open Policy Agent (OPA).

The API Create phase is the first stage in the API product lifecycle management process where you design, orchestrate, transform, document, and test your API. At this stage, modern API gateways like Apache APISIX can be helpful to build your API from scratch or import API definitions from a range of sources like OpenAPI YAML/JSON structure to register Route and Upstreams.

Apache APISIX is an API Gateway. By default, it stores its configuration in etcd, a distributed key-value store - the same one used by Kubernetes. Note that in real-world scenarios, we should set up etcd clustering to improve the resiliency of the solution. For this post, we will limit ourselves to a single etcd instance. Apache APISIX offers an admin API via HTTP endpoints. Finally, the gateway forwards calls from the client to an upstream. Here's an overview of the architecture and the required certificates:

One of the key features of modern API Gateways such as Apache APISIX is its support for GraphQL APIs. APISIX makes it easy to manage and scale GraphQL APIs using its flexible configuration system and powerful plugins. One such plugin is the degrapghql plugin, which allows us to convert the GraphQL API into a REST API. In this post, we will explore this feature with an example.

Secure your API: Use an to secure API Gateway by adding authentication, rate limiting, and other security features. It reduces the number of exposed APIs, organizations can reduce surfaces of attacks.

An alternative exists, though, if you're using an API Gateway. I'll describe how to do it with Apache APISIX, but perhaps other gateways can do the same. grpc-transcode is a plugin that allows transcoding REST calls to gRPC and back again.

I've used Kong but currently evaluating APISix as it's a more 'free/open' API gateway.

In this article, we will show you how to create a custom connector for the open-source Apache APISIX API Gateway in Power Platform as an alternative to Azure API Management in case you are building up additional components to an existing system with usable APIs and your system's infrastructure is hosted on-premises or on other cloud services provider rather than Azure.

Here's how to do it with Apache APISIX.

Apache APISIX is an open-source, high-performance API gateway built on top of Nginx. One of its powerful features is the ability to create serverless functions, which are small, stateless programs that can extend the functionality of Apache APISIX. In this article, we'll cover the basics of the Apache APISIX serverless plugin and how it can be used to trigger serverless functions in response to events.

sudo dnf -y install curl wget vim ETCD_RELEASE=$(curl -s https://api.github.com/repos/etcd-io/etcd/releases/latest|grep tag_name | cut -d '"' -f 4) echo $ETCD_RELEASE wget https://github.com/etcd-io/etcd/releases/download/${ETCD_RELEASE}/etcd-${ETCD_RELEASE}-linux-amd64.tar.gz tar xvf etcd-${ETCD_RELEASE}-linux-amd64.tar.gz cd etcd-${ETCD_RELEASE}-linux-amd64 sudo mv etcd* /usr/local/bin ls /usr/local/bin /usr/local/bin/etcd --version

Reading the standard library will give you ideas/insight about various Go idiomatic patterns/approaches, and you can see a full website/API implementation in the pkg.go.dev repository (https://github.com/golang/pkgsite). Projects like https://github.com/etcd-io/etcd may be interesting too.

Failure Detection and Recovery It’s not enough to have backup systems. It’s also crucial to detect failures quickly. Modern systems employ monitoring tools and rely on distributed coordination systems such as Zookeeper or etcd to identify faults in real-time: once detected, recovery mechanisms are triggered to restore the service.

Service Discovery: Microservices need to discover and communicate with each other dynamically. Service discovery tools like etcd, Consul, or Kubernetes built-in service discovery mechanisms help locate and connect to microservices running on different nodes within the infrastructure.

APISIX uses etcd to store and synchronize configurations.

etcd is an excellent key-value distributed database used internally by Kubernetes and managed by the CNCF. It's a great option, and that's the reason why Apache APISIX uses it too. Yet, it's not devoid of issues.

Someone on HN (https://news.ycombinator.com/item?id=36682595) suggested etcd (https://etcd.io)

In traditional mode, APISIX stores its configuration in etcd. APISIX offers a rich API to access and update the configuration, the Admin API. In standalone mode, the configuration is just plain YAML. It's the approach for GitOps practitioners: you'd store your configuration in a Git repo, watch it via your favorite tool (e.g., Argo CD or Tekton), and the latter would propagate the changes to APISIX nodes upon changes. APISIX reloads its configuration every second or so.

I am not sure neither. But this might overcome the etcd's soft storage limit of 8GB? [1]
