At Google Cloud blog published nice article about SLI tunning
Article not small, so I made some highlits for you:
- Compare SLI with what affects users (compared SLI metrics with mentions in social networks, posts on forums, support tickets). According to the received picture - adjust SLI to make it more realistic.
- Have simple ToDo for founding first alarm/spike for incident
- If you have no alarm (so sad...) and get info from users - Google have a specific tag: "Customer found it first" when they're carrying out their postmortems.
- If your SLIs are unhappy but customers are fine - Split logs created by users and service errors, change levels of abstraction, etc.
And, of cource, nearly any SLI is better than no SLI.

Towards an understanding of technical debt
Recently I have big discussion with programmers about "technical dept" and part of them try to said "we need time to rewrite all". So, it's not good idea, and this article explains why. Author describe five different phenomena that people mean when they say “technical debt”, and advocates understanding the full context rather than just assuming the folks that came before were fools.
Wrote in January 2016 but still actual.

Observability?! – Where do we go from here?
Long-read about this not simple question which covers reasons, pillars of observability, requirements for engineers and many other things.
Highly recommend to read this article for anyone who is even slightly interested in ~~observerless~~ Observability
Also, it have simply definition of Devops in one sentence:
>The DevOps philosophy promotes the concept of small, agile and cross-functional teams that completely manage the life cycle of the services they own.

Из нововведений:
- Explore: новый способ запросов, который позволяет делать запросы на лету для траблшутинга в реальном времени
- Grafana Loki: интеграция с Loki — который как Prometheus, но для логов
- Gauge Panel: отдельная панель для круговых показателей (gauges). Планируется цифровые показатели тоже привести к виду gauges
- New Panel Editor UX: новый редактор панелей
- Google Stackdriver Datasource: новый датасорс для догадайтесь чего
- Azure Monitor Datasource: перенесён из плагина в core датасорс
- React Plugin: Графана переезжает на React, React plugin позволяет проще создавать плагины
- Named Colors: цвета по названиям, а не кодам 😁
- Removal of user session storage: теперь проще сетапить Графану без стайтфул хранилища. Вместо хранения сессий выдаются короткоживущие токены

Google рассказывают о семи шагах в DevOps (методологию) в своём блоге.
1. Начните внедрение с малого проекта — остальные подтянутся
2. Используйте Open Source решения
3. Занимайтесь вопросами безопасности во время разработки, а не сбоку от неё
4. Следуйте лучшим практикам (хехехе. Тут пункт про SRE Book на самом деле)
5. Проводите внутренние тренинги внутри компании/команды и делитесь знаниями
6. No blame culture
7. Развивайте культуру: базируйте решения на данных, будьте открытыми, ставьте общие цели
Как-то так…

So I propose to read Six Strategies for Application Deployment in which the following practices are considered:
- Recreate
- Ramped
- Blue/Green
- Canary
- A/B testing

Six Strategies for Application Deployment
There are a variety of techniques to deploy new applications to production, so choosing the right strategy is an important decision…
AWS App Mesh is a service mesh based on Envoy that allows you to easily monitor and control communications across microservices applications on AWS. You can use App Mesh with microservices running on ECS, EKS and Kubernetes running on Amazon EC2. And it looks like you can switch traffic from one cluster to another.
In future they will add Fargate support.
In future AWS will add in App Mech something like OpenTracing solution for get visibility. And you will can use it with Cloudwatch, X-Ray, Datadog, Prometheus and Grafana!
Also, more slides from AWS Summit Berlin you can find in @aws_ru
