Не знаю, слышали вы или нет, но Elasticsearch (NoSQL БД, в основном используется для быстрого поиска по большому количеству текстовых событий) обзаведется поддержкой SQL в версии 6.3
SQL будет обрезаный, только для чтения, много трейдофов, но если вы не выучили DSL эластика, то для простых штук можно уже его и не учить.

Записки человека о лямбдах с AWS Startup Day:

- оптимизируйте свои функции
- используйте лямбды в VPC только если это необходимо. Они прогреваются дольше
- функции, для которых настроено > 1.8GB mem запускаются на с multicore CPU. Если у вас есть compute-intensive функции, имеет смысл исскустевнно повысить им лимит RAM
- лямбды огорожены от публичного Интернета
- отдавайте лямбдам отдельные подсети внутри VPC
- Use functions to TRANSFORM, not TRANSPORT
- степ-функции есть хорошо
- и ещё раз оптимизируйте
- мониторьте ваши функции

Если ты встречал странный base64 в параметрах веб-приложений, разбитый двумя точками - скорее всего это JSON Web Tokens.
Он состоит из заголовка, содержимого и подписи, считается одним из безопасных способов передачи информации, поддерживает различные алгоритмы подписи и вот это все. Правда не все реализации безопасны, то тип шифрования можно сменить на "None", то один алгоритм можно сменить на другой, где ключ заранее известен, а то и вовсе секретом будет являться какой-нибудь ChangeMe, где его, конечно же, не сменили. Но мир не без добрых людей, проверить корректность той или иной реализации и заодно перебрать секрет по словарю можно используя JWT Tool.
