A presentation about API Gateways

API Gateways

About me:

What is a API Gateway?
An API Gateway its an single entry point that receives requests
to its internal systems.

What is its purpose?
An API Gateway can have many roles, it can act like this five
examples:
❏ Filter: it can filters the requests made by different
environments (Mobile, Browser ...)
❏ Single Entry Point Layer: for the many others APIs that
you wish to expose
❏ Essential Component: to APIs management
❏ Traffic Router and Rate Limit
❏ Security Mechanism: logs, authentications and goes on

Difference between a API
Gateway and a API Manager
❏ A API Gateway is mainly used for security, while a API
Manager is used for analyze your system.
❏ Any API Manager has a API Gateway imbued within itself.

Difference between a API
Gateway and a API Manager

Some API Gateway Benefits!

Better Development!
With many services being used and controlled by the gateway
you can see which services are not being used so much and,
with that in mind, you can adapt other services that are more
used.

Buffer Zone!
Any attack against a service, controlled by a gateway, won't
affect your whole system. If the service goes down and the user
makes a request to it the gateway won't show to the user that
the service is down.

Activity Log!
With every service passing through the gateway it is possible to
prevent future errors.

A little bit of contextualization!

Let's imagine we have an online
store:
❏ We have different types of clients: mobile and browser
❏ The complexity of the services is different eg: one service
just fetch data from a DB while other makes a product
recommendation to the client.

So to solve those problems...

Both API Gateways and Service Meshes offer similar features and capabilities but are each implemented on a different axis in your application’s data plane. Draw those capabilities in a Venn diagram, you’ll see a lot of overlap between the API Gateways and Service Meshes. This is NOT a talk about the overlap. This is a talk about the things outside the overlap and why they matter (#HereBeDragons). The talk focuses on three questions around North/South & East/West Traffic. This talk is for a senior developer/architect on where to best inject cross-cutting concerns around security, observability and resiliency enabled by API Gateways and Service Meshes.

As APIs are becoming the building blocks of modern software, being able to rely on them is critical. Some might even say that APIs are the next big SaaS wave. But the problem is that as APIs become more universal, integrating them is not getting any easier, on the contrary. After interviewing over 50 engineering organizations, we’ve compiled a list of the best practices we came across and the challenges faced while building API integrations.

APIs are everywhere. Any business with a mobile app, modern web apps (SPAs), using the cloud, doing a digital transformation, integrating with business partners, running microservices or using kubernetes has APIs. There's a good foundation of AppSec knowledge out there - thanks in part to OWASP but API Security isn't exactly the same as AppSec. Additional complexity is part of the landscape with multiple competing API technologies like REST, gRPC and GraphQL plus stakeholders spread across multiple parts of the business. How to do you make sense of API Security landscape? This talk will cover the three fundamental areas to consider, the various chess pieces and the many ways those pieces can be put on your API chessboard. The goal is for you to leave knowing how to map out your API Security landscape and reach a state of solid API Security.

Codit presents the slide deck of the presentation on Swagger, given by Massimo Crippa (Codit) on Integration Monday. In this session, Massimo did go through the Swagger specification and some open source tools built on top of Swagger. This included Swagger editors and how they can be used to create our API stubs, the Swashbuckle tool to auto-generate swagger.json, to keep it in sync with the server code and to make it discoverable. Finally he demonstrated the Swagger integration in the API Management space (Azure API Management and Sentinet).

API Gateways provide functionality like rate limiting, authentication, request routing, reporting, and more. If you've been following the rise in service-mesh technologies, you'll notice there is a lot of overlap with API Gateways when solving some of the challenges of microservices. If service mesh can solve these same problems, you may wonder whether you really need a dedicated API Gateway solution? The reality is there is some nuance in the problems solved at the edge (API Gateway) compared to service-to-service communication (service mesh) within a cluster. But with the evolution of cluster-deployment patterns, these nuances are becoming less important. What's more important is that the API Gateway is evolving to live at a layer above service mesh and not directly overlapping with it. In other words, API Gateways are evolving to solve application-level concerns like aggregation, transformation, and deeper context and content-based routing as well as fitting into a more self-service, GitOps style workflow. In this talk we put aside the "API Gateway" infrastructure as we know it today and go back to first principles with the "API Gateway pattern" and revisit the real problems we're trying to solve. Then we'll discuss pros and cons of alternative ways to implement the API Gateway pattern and finally look at open source projects like Envoy, Kubernetes, and GraphQL to see how the "API Gateway pattern" actually becomes the API for our applications while coexisting nicely with a service mesh (if you adopt a service mesh).

This will be the first in a series of three blog posts on monitoring. In this article we’ll discuss monitoring Internet Information Services (IIS), the web hosting platform available in Windows Server editions. IIS is very popular in part because it provides such a compact service with lots of features and configurations. Most enterprises that use Windows Server editions are hosting their websites using IIS. When hosting critical applications, many companies use monitoring software to keep their system administrators informed about the overall behavior of their systems. Such software provides configurable alerts for performance counters, services and applications. We will talk about how to monitor IIS, what the most important performance counters are, and what services should be monitored when talking about Internet Information services.

Scenarios are the central artifact of the Behaviour Driven Development (BDD) process. Although many teams use scenarios and tools like Cucumber or SpecFlow to automate them, in many cases their scenarios contain a lot of details, particularly test data, and therefore they become too complicated to support collaboration with the business. The "essential" principle of scenario writing (scenario formulation) states that only those details should be included in the scenario that are relevant for the outcome. This talk provides help for those who struggle implementing this principle or would be interested to learn how you can create brief and maintainable scenarios.

AI/ML Infra Meetup May. 23, 2024 Organized by Alluxio For more Alluxio Events: https://www.alluxio.io/events/ Speaker: - Eric Wang (Software Engineer, @Uber) Uber has numerous deep learning models, most of which are highly complex with many layers and a vast number of features. Understanding how these models work is challenging and demands significant resources to experiment with various training algorithms and feature sets. With ML explainability, the ML team aims to bring transparency to these models, helping to clarify their predictions and behavior. This transparency also assists the operations and legal teams in explaining the reasons behind specific prediction outcomes. In this talk, Eric Wang will discuss the methods Uber used for explaining deep learning models and how we integrated these methods into the Uber AI Michelangelo ecosystem to support offline explaining.

Les Buildpacks existent depuis plus de 10 ans ! D’abord, ils étaient utilisés pour détecter et construire une application avant de la déployer sur certains PaaS. Ensuite, nous avons pu créer des images Docker (OCI) avec leur dernière génération, les Cloud Native Buildpacks (CNCF en incubation). Sont-ils une bonne alternative au Dockerfile ? Que sont les buildpacks Paketo ? Quelles communautés les soutiennent et comment ? Venez le découvrir lors de cette session ignite
