Edge기반 기계 학습: AWS IoT Greengrass를 활용한 이미지 분류 모델 훈련 (Part 2) 이 블로그 게시물의 1부에서는 재활용 시설의 분류기가 네 가지 음료 용기를 식별할 수 있도록 해 주는 이미지 분류 모델을 생성했고, 이 모델을 AWS IoT Greengrass Image Classification Connector를 사용하여 AWS IoT Greengrass 코어 디바이스에 배포하는 것을 구현했습니다. 지난 re:Invent 2018에서 발표된 AWS IoT Greengrass 커넥터를 사용하면 코드를 작성하지 않고 IoT Greengrass 코어 디바이스를 타사 애플리케이션, 온프레미스 소프트웨어 및 AWS 서비스에 연결할 수 있습니다. 1부 끝부분에서 우리는 음료 용기 예측이 항상 정확하거나 높은 신뢰도를 일관적으로 제공하지 못할 수 있다는 것을 볼 수 있었습니다. 2부에서는 예측 신뢰도 임계값을 위반하는 이미지를 업로드하도록 애플리케이션을 확장하고, 모델을 재훈련하여 IoT Greengrass 코어 디바이스에 다시 배포하는 것을 구현 하겠습니다. 참고: 이 블로그 게시물의 정보는 1부의 내용에 상당 부분 의존하고 있습니다. 계속하기 전에 1부의 단계들을 모두 완료하시는 것을 권장드립니다. 개요 이 게시물에서는 1부에서 생성한 음료 분류기 [ more… ]

Sampling Requests with NGINX Conditional Logging

2019-04-25 KENNETH 0

Sampling Requests with NGINX Conditional Logging NGINX can record a very detailed log of every transaction it processes. Such logs are known as access logs, and you can fine‑tune the detail that is recorded for different services or locations with a customizable log‑file format. By default, NGINX logs every transaction it processes. This might be necessary for compliance or security purposes, but for a busy website, the volume of data generated can be overwhelming. In this article, we show how to selectively log transactions based on various criteria, and how to use that knowledge to sample data points about requests in a quick and lightweight way. Except as noted, this post applies to both NGINX Open Source and NGINX Plus. For ease of reading, we’ll refer to NGINX throughout. Background – Quick Overview of NGINX Access Log Configuration NGINX access logs are [ more… ]

Is Your API Management Solution Really Secure?

2019-04-23 KENNETH 0

Is Your API Management Solution Really Secure? NGINX is the industry’s most ubiquitous API gateway, an infrastructure component that processes API traffic in API management solutions like those from Apigee, Axway, IBM DataPower, Kong, Red Hat 3scale, and Torry Harris. Combine that with the fact that more than 40% of the users we surveyed in 2018 have deployed NGINX Plus as an API gateway, it’s fair to say that NGINX is processing most of the world’s API traffic. That’s not too shabby, considering that Akamai puts API traffic at 83% of the world’s Internet traffic. Why is NGINX so ubiquitous in the world of APIs? Because NGINX delivers high performance, security, and authentication services – all critical to your API environment. NGINX prevents DDoS attacks by enforcing rate limits on requests or bandwidth limits on specific users, and NGINX Plus provides authentication and fine‑grained access control to protect [ more… ]
