This all started with a blog post back in 2020, from a tech curiosity: what's the fastest way to scale containers on AWS? Is ECS faster than EKS? What about Fargate? Is there a difference between ECS on Fargate and EKS on Fargate? I had to know this to build better architectures for my clients. In 2021, containers got even better, and I was lucky enough to get a preview and present just how fast t

クラウドでは、利用者による物理メディアの破棄（消磁や破砕）はできません。今回は、クラウド環境で利用者が行えるデータ破棄の方法（Cryptographic Erase：暗号化消去）をためしてみました。 こんにちは、nkhrです。 オンプレ環境では、データ漏洩（第三者による意図しないデータ取得）を防ぐために、メディア破棄の統制を行っていると思います。クラウドでは、利用者による物理的なメディア破棄が行えないため、統制を行う場合は別の方法を考える必要があります。 クラウド環境で利用できるデータ破棄の方法として、「Cryptographic Erase（CE:暗号化消去）」があります。 今回は、下記のブログで紹介されている暗号化消去（CE）を試してみました。暗号化消去は、NIST 800-88にも記載されている方法です。 クラウドにおける安全なデータの廃棄（Amazon Web Service ブロ
