O Cloud Native se tornou uma grande palavra de ordem em todo o mundo, um termo que é praticamente usado por todos em todos os momentos. Mas o que isso significa? Quais são as vantagens que ele traz ao seu aplicativo e ao seu dia como desenvolvedor ou arquiteto de software? O que há de novo no mundo Java e quais são as etapas a seguir para um aplicativo em nuvem nativo? Esta apresentação é um guia passo a passo que praticamente o guiará na implementação de serviços de computação em nuvem de maneira eficaz e eficiente.

5. Cloud Native

6. “Cloud-native is an approach to building
and running applications that exploits
the advantages of the cloud computing
model.”
Cloud Native

7. “Cloud-native is a different way of thinking
and reasoning about software systems. It
embodies the following concepts: powered
by disposable infrastructure, composed of
bounded, scales globally, embraces
disposable architecture.”
Cloud Native

8. “In general use, ‘cloud-native’ is an
approach to building and running
applications that exploits the advantages
of the cloud-computing delivery model.
‘Cloud-native’ is about how applications
are created and deployed, not where.”
Cloud Native

9. “Independent DURS ultimately comes up
in every discussion on cloud-native
concepts; to independently Deploy,
Update, Replace and Scale.”
Cloud Native

10. “Cloud-native is more than a tool set. It is a
complete architecture, a philosophical
approach for building applications that
take full advantage of cloud computing.”
Cloud Native

11. “Cloud-native technologies empower
organizations to build and run scalable
applications in modern, dynamic
environments such as public, private,
and hybrid clouds. Containers, service
meshes, microservices, immutable
infrastructure, and declarative APIs
exemplify this approach.”
Cloud Native

12. Cloud-native is a term used to describe
container-based environments.
Cloud Native

13. A set of good practices to
optimize an application in
the cloud through:
● Containerization
● Orchestration
● Automation
Cloud Native

14. PORA
Package Once, Run Anytime
WORA
Write Once, Run Anywhere
Containers vs.
Java

15. The Best Practices

16. ● Codebase
● Dependencies
● Config
● Backing services
● Build, release, run
● Process
● Port binding
● Concurrency
● Disposability
● Dev/prod parity
● Logs
● Admin processes

18. “Certainly, we always read great things
about the microservices architectures
implemented by companies like Netflix or
Amazon. So let me ask a question: how
many companies in the world can be
Netflix and Amazon?”

26. ‘The cloud’ is complex
They need to focus on turning business ideas into
code, and and let somebody else do the rest.
Their energies shouldn’t be consumed
managing various clouds
Challenge
Today’s reality
All companies are now software companies,
expecting to deliver great customer experiences.

27. Platform.sh was built
on the idea that your
application comes first
It’s what your customers care about.
It’s what drives you and your team.
We handle the rest.

28. We’re a polyglot, multicloud PaaS, with
continuous deployment built in.
At Platform.sh we believe your code
should just run. Monoliths?
Microservices? Stateful? Stateless?
Develop and deliver them all with
consistent tools.
Much more than
hosting

29. Infrastructure as
code
Add MySQL, PostgreSQL, MongoDB, Kafka,
Elasticsearch, Solr, Redis, RabbitMQ, or
InfluxDB to your project with a few lines of
code. Infrastructure changes are versioned
and auditable.
Service updates and security?
That’s on us. No more effort wasted on
patching your fleet.

30. Application
name: app
type: "java:11"
disk: 1024
hooks:
build: mvn clean package
relationships:
database: "db:postgresql"

31. Services
database1:

32. Route

33. Config Reader
@Configuration
public class DataSourceConfig {
@Bean(name = "dataSource")
public DataSource getDataSource() {
Config config = new Config();
MySQL database = config.getCredential("database", MySQL::new);
return database.get();
}
}

34. Config Reader
@Configuration
class DataSourceConfig {
@Bean(name = ["dataSource"])
fun getDataSource(): DataSource {
val config = Config()
val database = config.getCredential("database") { MySQL(it) }
return database.get()
}
}

35. Config Reader
Config config = new Config();
final MongoDB mongo = config.getCredential("mongodb", MongoDB::new);
final MongoClient mongoClient = mongo.get();
Config config = new Config();
Configuration configuration = new Configuration();
configuration.addAnnotatedClass(Address.class);
Hibernate credential = config.getCredential("database", Hibernate::new);
SessionFactory sessionFactory = credential.getMariaDB(configuration);
