Cada día vemos cómo cobra mayor importancia poder desplegar de forma habitual nuestras aplicaciones e infraestructura. Repasaremos algunas buenas prácticas y consejos para que esto no suponga un quebradero de cabeza.

CI/CD

18. • Requires developers to integrate code into a shared
repository several times a day.
• Allow teams to detect problems early.
• 2 hours per build is not agile!

22. • Continuous Deployment (CD) essentially, it is the practice
of releasing every good build to users.
• Every change is proven to be deployable at any time.

Infrastructure as code

26. An ARM template is a JSON
(JavaScript Object Notation) script.
This script includes the resource(s)
that are being deployed to an
Azure Resource Group.

“Every artifact that could
possibly modify the behaviour of
the system in production is
source…”

27. Terraform is a tool for building,
changing, and versioning
infrastructure safely and efficiently.
Terraform can manage existing and
popular service providers as well
as custom in-house solutions.

Best practices

29. The best way to store secrets is doing it in…
• In your code.
• In your environment definition.
We’re seeing a set of good tools emerge that offer secrets
as a service. With this approach, rather than hardwiring
secrets or configuring them as part of the environment,
applications retrieve them from a separate process.
Secrets as a Service

30. “Tags will make your life easier, use them”
Resources
@plainconcepts 30

31. • Understand and use different Access tiers.
• Data also has a live cycle.
• Be ware of the data you’re storing.
• Enable secure transfer requirement.

34. • Be aware of how resources connect, where
information travels, and what is publicly
exposed.
• Isolate networking resources in its own resource
group.
Networking
@plainconcepts 34

35. • Use CNI for advanced networking and connect AKS to
the vnet.
• New feature in preview: cluster autoscaler.
• Configure liveness and readiness.
• Deploy with a replica set of 2 pods to ensure your
system will scale properly.
Kubernetes
@plainconcepts 35

36. • Pod limits help prevent one or two runaway pods
from taking too much CPU and memory from the
node.
• Secure pod access to resources
• Don’t statically create and assign persistent
volumes.
Kubernetes
@plainconcepts 36

Monitoring and Feedback

38. • Application Insights: an application performance
management service for web applications that enables you
to do all the monitoring of your website performance in
Azure.
Telemetry Instrumentation
@plainconcepts 38

39. • Azure Monitor is a service that helps you monitor your
applications and the resources they rely on.
• A Log Analytics workspace is a unique environment for
Azure Monitor log data. Each workspace has its own data
repository and configuration, and data sources and
solutions are configured to store their data in a
particular workspace.
Monitor Infrastructure
@plainconcepts 39

40. • Grafana is an open source metric analytics & visualization
suite. It is most commonly used for visualizing time series
data for infrastructure and application analytics.
