GCP Service Account Example

this is an example of gcp service account. Clearly, service account has a private key and a certificate.

So GCP uses public-key cryptography (+ certificate to validate wheather public key is falsificated) to authenticate the service account.

dogrun 
01 gcpとfirebaseのfunctionの使い分け
・function自体は同じ、違いは開発者のデプロイ方法の違い

02 functionでpythonサポートの予定はあるか
頑張るが今の所ない。

03 firebaseとgcpの壁
・モバイルならfirebase、クラウドならgcp、functionsは中間
・schedulerをfirebaseに持て来るよていはある
