7. WHAT IS
KUBERNETES?
Kubernetes is a portable, extensible, open-
source platform for managing
containerized workloads and services, that
facilitates both declarative configuration
and automation. It has a large, rapidly
growing ecosystem. Kubernetes services,
support, and tools are widely available.

automatically spin up the pods

Decreased Dependencies on Shared
Environments
Ability to get to a complicated Failure State
quickly
Automation made easier
Cheap disposable Environments
Direct Access to Logs, Monitoring
Encourages “Shift Left Testing” Model
20. RESOURCE UTILIZATION
Resources are utilized
based on certain rules
via a central
orchestrating process.
Reduces the costs
associated with
maintenance and
operations
22. A/B TESTING
Zero downtime
Real time users traffic testing
Easy and quick rollback

internal to clusters
25. E2E TEST
(AUTOMATION)
• Using Selenium Grid for distributing
your tests. Its lot better if its deployed
via Kubernetes
• Selenium 4 now offers more advanced
monitoring by enabling “tracing
capability
27. OBSERVABILITY
It is a measure of how well internal states of a system
can be inferred from knowledge of its external outputs.
It helps bring visibility into systems. – Wikipedia
