We'll see how the deployment of apps has been transformed by game-changing tools like Kubernetes.

9. HOW DO I DEPLOY MY APP

11. Docker
WHAT IS IT?
Docker containers are like virtual machines. They
include all the dependencies and environment that
surrounds your application.

16. GraphQL
WHAT IS IT?
Data query and manipulation language for APIs. It
removes the over-fetching, under-fetching and
other backend discussions, as we can shape the
data that we need.

22. WHAT IS IT?
It’s a multilanguage RPC framework. It uses API
descriptors like SOAP and it’s very optimized at the
wire-level

29. WHAT IS IT?
Kubernetes is an open-source tool designed to
organize automatic deployments and manage
containerized applications
Kubernetes

30. KUBERNETES
● Pods
● Deployments
● Services
● Ingress Controller

31. POD
Is the minimum unity in Kubernetes. It could be one
or several grouped containers.
Kubernetes

33. Deployment
A deployment is a group of replicas of the same
pod.
Kubernetes

37. Kubernetes
Services
It groups our pods (or deployments) and exposes
them inside the cluster.

39. Kubernetes
Ingress
It’s the NGINX of Kubernetes. It routes the traffic
from the outside world into the cluster.

46. Missing Concepts
CONFIG MAPS
Decouples
configuration
from the each
deployment.
Specially useful
when sharing
configuration
between
deployments.
NAMESPACES
Virtual cluster
inside the same
physical cluster.
SECRETS
Similar to config
maps but used for
storing secret
data.
JOBS
One time run
containers. Useful
for things like
database
migrations.

48. WHAT IS IT?
It’s a package manager for Kubernetes. Allows you
to install and configure services on the fly.

52. HELM MAIN FEATURES
ROLLBACK
Versioning the deployments
allows performing rollbacks
if something goes wrong
CONFIGURATION
Allows to parametrize the
inner parts of the
infrastructure
VERSIONING
Manage the different
versions of your
deployments

53. Missing tools
Zipkin
Gathers traffic
metrics between
services. Useful
to see the fill
trace of a request.
ISTIO
Wrapper for
services. Allows
automatic load
balancing,
network
monitoring,
enhances
security...
ELK
ElasticSearch
stores our logs.
Logstash
normalizes and
collects them into
ElasticSearch.
Kibana for charts
and
visualizations.
SCRYER
Predictive
autoscaling. Uses
previous traffic
metrics and
makes a
prediction model
to autoscale
before traffic
arrives.
