AaaSからZaaSまで「as a Service」を探したら色々なサービスが見えた話

#はじめに
近年IT界隈では、IaaS(Infrastructure as a Service)やPaaS(Platform as a Service)などの~~ as a Serviceという言葉をよく聞くと思います。
ここでは、それらをまとめて、 [A-Z]aaS と呼びたいと思います。
FirebaseなどのBaaS(Backend as a Service)やAWS LambdaなどのFaaS(Function as a Service)など色々な[A-Z]aaSを聞く機会が増えてきたんじゃないでしょうか。
今回は色々な[A-Z]aaSを探してみました。結果としては 910個 もの[A-Z]aaSを見つけることができました。（探した結果を全て、後半に表示してあります。）

#[A-Z]aaSの探し方
最初の二文字を固定して、グーグル検索のサジェストに表示されるものを収集することにします。
英字が26文字なので、26*26=676パターンあります。
（注意） グーグル検索のサジェストに出てきただけで、実際にそういうサービスがあるとは限りません。

#個人的に面白かった５選

###ZaaS (Zangyou as a Service)
サービス残業のことです。まさかの日本語ですね。
（参考）https://monobook.org/wiki/ZaaS_(Zangyo_as_a_Service)

###FaaS (Failure as a Service)
障害をシミュレートするサービスだそうです。
（参考）https://www.apriorit.com/dev-blog/567-failure-as-a-service
https://dev.classmethod.jp/testing/reinvent2018-gremlin/

###SaaS (Service as a Service)
サービスとしてのサービスという名の通り、サービスを顧客にあったように、紹介するみたいなイメージでしょうか。
(参考）https://www.ft.com/content/f88bc87a-0e4b-11e2-8b92-00144feabdc0

###CaaS (Crime as a Service)
他のサービスを攻撃するために作られたツールをサービスとして提供するというもののようです。危険ですね。。。
（参考）https://www.entrepreneur.com/article/298727

###BaaS(Brain as a Service)
MicroTaskという会社が提案しています。
CPU + GPU + HPU(Human Processing Unit)で処理を加速するのだそうです。

探す方法

（検討１）　Google Suggest APIを使う

Google Suggest APIというものがあり、ある単語を打った時のグーグル検索のサジェストを取得することができます。（参考）https://so-zou.jp/web-app/tech/web-api/google/suggest/
しかし、[A-Z]aaSをサジェストから探すときには、普通にサジェストを得るのではなく、まず検索バーに「as a Service」を打っておき、その後に調べたい先頭の文字を打つ必要があります。そのためGoogle Suggest APIではどういったURLのページにリクエストを送ればいいのか分かりませんでした。。。これが可能であれば、収集のための作業量が10分の１になっていたと思います。

(検討２）　python OCR を使う

サジェストされた結果を手で打っていくことだけは避けたかったため、OCRで画像情報を文字列に変換していくという方法にします。
chromeの検索バーにひたすらAa as a ServiceからZz as a Serviceまでを打ち、サジェストされている画面をスクリーンショットで取っていきます。（スクリーンショットを取ること676回)

以下のプログラムでOCRを使って、画像から文字情報を抜き出します。
そのあとに、[A-Z]aaSの形式に当てはまる形のものを、抜き出します。
以下のコードで、画像から[A-Z]aaSを抜き出すことができました。

main.py

from PIL import Image
import glob

import pyocr
import pyocr.builders

tools = pyocr.get_available_tools()
tool = tools[0]

langs = tool.get_available_languages()
lang = langs[0]

# a ~ zで回す
for i in range(97, 97+26):
    image_files = glob.glob("images/%c/Screen*"%chr(i))
    words = []
    for image_file in image_files:
        im = Image.open(image_file)
        croped_image = im.crop((300, 250, 1000, 730)) #基準

        # OCRで画像から文字を一行ずつ読み取る
        line_and_word_boxes = tool.image_to_string(
            croped_image,
            lang=lang,
            builder=pyocr.builders.LineBoxBuilder()
        )

        #得た文字列から一列ごとに読み取る
        for line_words in line_and_word_boxes:
            if line_words.content.endswith('as a service') and line_words.content.startswith(chr(i)):
                word = line_words.content.capitalize()
                word = word.replace('service', 'Service')
                print(word)
                words.append(word)

    #改行コードで連結して、ファイルに書き込む
    words = '\n'.join(list(set(words)))
    with open("result/"+chr(i)+".txt", 'w') as f:
        print(words, file=f)

#A-Zまで
以下に取得した[A-Z]aasを全て掲載します。今回、調べることができたのは、910個と、とてつもない量です。スクロールするのもめんどくさいです。探したのは、グーグル検索のサジェストから得た結果だけなので、実際にはもっとあると思います。

#終わりに
とてつもない量のサービスですね。今まで普通にあったサービスも、ゴロがいいからみたいな理由で、as a Serviceと名づけられてるのかなと思いました。
これからは何かをしたいと思う時、自分で準備するよりもサービスを利用した方がいいということでしょうか。
以下の２年ほど前の記事にもまとまっていたので紹介しておきます。
