Microservices e o desenvolvimento cloud-native 10 anos depois

Nós estamos no ano de 2021 e uma nova consciência se formou no mercado sobre a importância da transformação digital nas empresas consolidando uma verdadeira corrida na contratação de profissionais de tecnologia e desenvolvimento de software.

Durante esse keynote o Ramon Durães que é CEO da DevPrime e Microsoft MVP palestrou sobre a evolução dos microservices e a evolução do mercado de tecnologia.

Para suportar a modernização de aplicações muitas estratégias de desenvolvimento evoluíram ao longo do anos de delas é um padrão de desenvolvimento de microsserviços que apoia diretamente o movimento de transformação digital proporcionando um maior alinhamento do negócio com a necessidade de evolução continua.

Ao falarmos sobre o desenvolvimento de microservices ou cloud-native application development os principais benefícios que vem mente estão relacionados a: Agilidade e inovação contínua, Desacoplamento, Estruturado por contexto de negócio, Independência na manutenção, Escalabilidade e
Disponibilidade.

Essa palestra foi apresentada na conferência VSSUMMIT 2021 e você pode acompanhar mais detalhes abaixo:

6. ENABLING INNOVATION WITH MICROSERVICES Source: Kong / Digital Innovation Benchmark, 2021 https://bit.ly/2YYTz8p 87% of tech leaders believe microservices-based applications are the future. 33% of organizations have already transitioned entirely to distributed architectures. The main reasons to adoption of microservices: Increase security (63%) Integrate new tech faster (59%) Increase speed of development (57%) Increase infrastructure flexibility (52%)
