CES 2021: HP aims to appeal to consumers and remote workers with wide range of devices COVID-19 has changed the way people live and work this past year, so much so that HP research has shown people in the U.S., U.K. and Japan using their personal PCs an additional seven hours a week. Photography, writing stories/articles and live streaming emerged as the top three activities. HP has unveiled a lineup of Windows 10 devices at CES 2021 to help those spending more time on their devices pursuing creative and professional goals. With fingerprint readers and IR cameras, you can login via Windows Hello for increased security. The HP ENVY 14 is a mobile personal creative studio that has a multi-touch enabled IPS display that provides 11% greater viewing area than a traditional 16:9 laptop. There’s a physical shutter for the [ more… ]

Hello, New API – Part 1

2021-01-09 KENNETH 0

Hello, New API – Part 1 Learning a new system API may feel like a daunting task. As a network engineer you may feel unsure about how to begin. Fortunately, the way to learn any API‑based system – whether a controller product, a cloud system, or even a device API – follows the same set of steps. In this post, I guide you through the initial steps and highlight key aspects to note as you are learning to use a new API. You may be using commercial products and open source projects; for convenience, here the term product refers to both. This first post in a two‑part series focuses on documentation, client libraries, and API authentication. Part 2 will focus on API read‑only and read‑write activities. Documentation The first step is to locate the API documentation, and the first item to look for [ more… ]

CDK8s를 이용하여 쿠버네티스 애플리케이션을 정의하고 관리하기

CDK8s를 이용하여 쿠버네티스 애플리케이션을 정의하고 관리하기 이 글은 쿠버네티스 애플리케이션을 개발하면서 사용하는 쿠버네티스 매니페스트를 YAML 파일로 작성하고 관리할 때의 어려움을 해결하고 그것들을 효율적으로 쿠버네티스 클러스터에 지속적으로 배포하기 위한 모범 사례를 제안하기 위해 쓰여졌습니다. 이 글에서는 AWS Cloud Development Kit (CDK), CDK for Kubernetes (CDK8s)를 이용하여 쿠버네티스 매니페스트를 정의하는 방법을 다룰 것이며 특히 쿠버네티스, 인프라로서 코드(Infrastructure as Code, IaC) 그리고 지속적 통합 및 배포(Continuous Integration/Continuous Delivery, CI/CD)에 대한 이해가 있는 독자들을 주요 대상으로 하고 있습니다. 쿠버네티스는 컨테이너화된 애플리케이션을 자동으로 배포, 스케일링 및 관리해주는 오픈소스 시스템으로 개발자와 운영자들에게 열렬한 지지를 받으며 발전을 하고 있는 컨테이너 오케스트레이션 도구입니다. 다른 오케스트레이션 도구들과 마찬가지로 쿠버네티스는 사용자가 원하는 어떤 의도를 담은 레코드, 즉 원하는 상태 (desired state)를 쿠버네티스 오브젝트로 정의하여 컨테이너 오케스트레이션의 메커니즘을 구현합니다. 쿠버네티스에서 오브젝트를 생성할 때, 오브젝트에 대한 기본적인 정보(이름과 같은)와 더불어, 의도한 상태를 기술한 오브젝트 스펙을 제시해야만 합니다. 대부분의 경우 정보를 YAML 파일로 [ more… ]

NGINX and HAProxy: Testing User Experience in the Cloud

2021-01-08 KENNETH 0

NGINX and HAProxy: Testing User Experience in the Cloud Many performance benchmarks measure peak throughput or requests per second (RPS), but those metrics can oversimplify the performance story at real‑world sites. Few organizations run their services at or near peak throughput, where a 10% change in performance either way can make a significant difference. The throughput or RPS a site requires is not infinite, but is fixed by external factors like the number of concurrent users they have to serve and the activity level of each user. In the end, what matters most is that your users receive the best level of service. End users don’t care how many other people are visiting your site. They just care about the service they receive and don’t excuse poor performance because the system is overloaded. This leads us to the observation that what [ more… ]
