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: https://vssummit.com.br
