Хотите сэкономить на использовании AWS Lambda и повысить производительность функций? В этом выпуске подкаста мы подробно разберем способы оптимизации serverless приложений и раскроем неочевидные на первый взгляд тонкости настройки Lambda.

Мы начнем с того, как правильно выбрать объем оперативной памяти для функций. Оказывается, это напрямую влияет на производительность и стоимость.

Далее разберем технологию Snap Start, которая позволяет минимизировать холодные старты Java функций.

Поговорим о предварительном создании пула функций с Provisioned Concurrency. Это хороший способ ускорить отклик критичных Lambda.

Также узнаем, как использование компилируемых языков вроде Rust и Go вместо интерпретируемых может значительно прибавить скорость выполнения кода.

И еще много других полезных советов - от фильтрации ненужных событий до оптимальной инициализации функций.

В общем, если хотите выжать максимум из Lambda - обязательно послушайте этот выпуск!

Docker Systems Status Page

November 11, 2023 16:23 UTC [Investigating] We're investigating a partial disruption of registry services.

November 11, 2023 18:15 UTC [Monitoring] Docker Hub was temporarily disrupted (with unusual error rates and high latency on registry operations such as push/pull and auth) due to unusual traffic patterns.

The incident has been handled, and operation error rates/latency have returned to normal.

We will continue monitoring before resolving.

EKS + EBS CSI snapshot controller:

https://docs.aws.amazon.com/eks/latest/userguide/csi-snapshot-controller.html

CSI snapshot controller enables the use of snapshotting functionality in compatible CSI drivers, such as the EBS CSI driver.

▫️ We recommend that you install the CSI snapshot controller through the EKS managed add-on.
▫️ Alternatively, if you want a self-managed installation of the EBS CSI snapshot controller, see Kubernetes external-snapshotter on GitHub.

Судя по всему, лента обновлений AWS замерла в связи с предстоящим через неделю re:Invent 2023 (не забываем зарегистрироваться), поэтому буду скидывать интересное вместо @awsfeed.

P.S. Полный список AWS обновлений за прошлую неделю можно найти на @awsweekly.

​​Теперь можно ссылаться на Security Groups из другой VPC, которая присоединена через Transit Gateway:

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/security-group-rules-reference.html#tgw-vpc-rules

Раньше можно было ссылаться на SG из других VPC только через VPC peering, теперь можно из через TGW. Правда для этого потребуется обновить TGW или VPC attachment:

https://docs.aws.amazon.com/vpc/latest/tgw/tgw-sg-updates.html

Особенности:

▪️ Ссылаться через TGW peering нельзя (VPC -> TGW -> TGW peering -> TGW -> VPC, только VPC -> TGW -> VPC).
▪️ Ссылаться можно лишь в правиле для входящего трафика.
▪️ Не работает на древних виртуалках (только Nitro-based EC2 instances).
▪️ Не работает на любых виртуалках, расположенных в древних датацентрах, конкретно подзона use1-az3 (которую всегда рекомендовал исключать).
▪️ Не работает, как минимум пока, с PrivateLink и Reachability Analyzer.

Кому-то мелкая вещь и бессмысленная вещь, а кому-то упрощение управление зоопарком Security Groups в сложной сети.
