Проблема: необходимо распределить трафик между несколькими TCP-серверами.
Решение: в книге "Nginx Cookbook: Advanced Recipes for High-performance Load Balancing" автор показывает использование модуля stream для балансировки нагрузки на уровне транспортного слоя.
Пример кода:
stream { upstream mysql_read { server read1.example.com:3306 weight=5; server read2.example.com:3306; server 10.10.12.34:3306 backup; }
server { listen 3306; proxy_pass mysql_read; } }
Преимущества:
— Поддержка балансировки для TCP-сервисов. — Гибкая настройка весов серверов. — Резервирование серверов для повышения надёжности.

The cloud-based messaging platform is also adding Anonymous Group Admins feature. As per Telegram, this feature is being introduced for safer protests. As per the Telegram blog post, users can “Toggle Remain Anonymous in Admin rights to enable Batman mode. The anonymized admin will be hidden in the list of group members, and their messages in the chat will be signed with the group name, similar to channel posts.”
How to Use Bitcoin?
n the U.S. people generally use Bitcoin as an alternative investment, helping diversify a portfolio apart from stocks and bonds. You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. Big companies that accept Bitcoin include Overstock, AT&T and Twitch. You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
