SAP CloudFoundryおよびSAPHANAXSAで.NetCoreアプリケーションを実行しようとしています

SAPは現在CloudFoundry（CF）を積極的に開発しており、クラウドインフラストラクチャのコア要素としてSAP CloudPlatformに実装しています。 CFはPaaSとして機能し、SCP環境でアプリケーションを実行できるようにします。この記事では、プロジェクトを本番環境にリリースするためにCFを準備する方法（「稼働」フェーズ）と、Cloud FoundrySCPおよびHANAXSA環境にアプリケーションをデプロイする方法について説明します。例を見て、アプリケーションを実行するための制御された環境を提供しながら、サーバーコンピューティングリソースをインテリジェントに管理する方法を示します。
