Cloud has become a business necessity, but “there is still a tremendous amount of headroom left for most organisations”, said Joe Rogus, advisory director at Gartner, during his keynote on the future of cloud at the recent Gartner IT Infrastructure, Operations and Cloud Strategies conference in Sydney.

I tested the JVC DLA-NZ700, and its performance is nothing short of a revelation for a mid-range projector

3 weeks ago | techradar.com | Stephen Withers

The JVC DLA-NZ700 has a lighter and more compact chassis than the company's NZ800 and NZ900, but uses the same third-generation D-ILA chipset, laser light source, and filter for wide colour gamut coverage. There are no HDMI 2.1 inputs, which in turn means the new projector can’t support 4K/120Hz, and there’s no low-latency mode for gaming.

「Kubernetes」運用の“ベストプラクティス”と“ワーストプラクティス”9選

Kubernetes導入における代表的なワーストプラクティスは以下の通り。コンテナの大きな利点は「移植性」だが、特定のクラウドベンダー固有のサービスや構成に依存してしまうと、移植性――ひいてはKubernetes導入のメリットが損なわれる。移植性を実現するには、設計段階からの工夫が必要だ。「特にマイクロサービスは、移植性を前提に設計されていない場合、複数クラウド間でシームレスに稼働させるのは難しい」とアシュジャリ氏は指摘する。マイクロサービスは、クラウドサービスの中核として、セキュリティや可観測性（オブザーバビリティ）などの重要な機能を担う。ただし、クラウドベンダーが提供するマイクロサービスは独自仕様が多く、他クラウドサービスへの移行時にリファクタリング（再設計）が必要になるケースが多い。近年、コンテナ化されたワークロード（特定のシステムやアプリケーションに関するタスクや処理）をプライベートクラウドやオンプレミスシステムで運用する傾向が企業の間で強まっている。背景には、データ主権（データの制御や管理に関する権利）、セキュリティ、管理権限の確保といったニーズの高まりがある。...
