Google Cloud Endpoints — is the superstructure over Google App Engine (GAE) for creation of API for web and mobile applications doing development it is simpler also the atorization including "from box" protection against DoS-attacks, OAuth 2.0, the web interface for testing API, SSL, atomatichesky scalability (the site will not fall under habra-effect), and also possibility of use of services available in Google App Engine (sending and reception of e-mail and XMPP messages, data loading from the Internet (URL Fetch service), tasks of the schedule (Task Queues and Scheduled Tasks), etc.)

GAE is free within initial quotas which allow to try and test service, and also to provide free functioning of the website which does not have heavy loads. At exhaustion of quotas service to become paid.

Idea of service that it does all or most part of work of the system administrator, plus some part of work of the programmer. This service can be interesting to startups as allows by small forces and in kotrotky terms to start detail design.

Google бесплатно раздает $300 на аккаунт в GAE

2 years, 5 months ago


Увидел статью про $25 от Amazon и вспомнил, недавно было необходимо создать новый апп в GAE и тут увидел, что Google даёт $300 кредит на все сервисы Google Cloud Platform. Надеюсь это сподвигнет к развитию платформы PaaS в целом везде.

Но самое главное, что ?Гугл? не отключает при этом бесплатные квоты. Т.е. расход денег идёт только после израсходования квот.

Together more cheerfully: python + flask + google app engine

2 years, 7 months ago
Background: I, as well as many on Habrakhabr, devilishly like to listen to music. Most often I do it in VKontakte. Sometimes already sfomirovanny playlist bothers? there is a wish for something new; but so that not strongly differed from that already is. For this purpose on all services giving opportunity of listening of music there are recommendations. I admit honestly, recommendations in VKontakte terrify me. Can to someone it is pleasant, but local selection causes desire to close the browser in me (IMHO, of course). Generally, I have solved this situation for myself to correct and implement own recommendations with use of API VKontakte and Last.fm. As I heard much and read about Google App Engine, but never it used, have been decided to join this platform.

At once I will tell that here I will not describe interaction subtlety about API or the fitting algorithm of recommendations. About it? in the following articles, can be. In this article only process of creation, setup and deploya applications on the Google App Engine platform with use of python and flask is described.
Request to report about typographical errors and inaccuracies in pm. Thanks.
