Message Patterns Which problems are solved? File Transfer Shared Database Remote Procedure Invocation Messaging Globalcode – Open 4 education

Message Queue A message queue is a form of asynchronous service -to-service communication used in serverless and microservices architectures. Messages are stored on the queue until they are processed and deleted. Each message is processed only once, by a single consumer. Globalcode – Open 4 education

Controle de Fluxo Síncrono e Assíncrono Globalcode – Open 4 education

Chamada sincrona If an API call is synchronous, it means that code execution will block (or wait) for the API call to return before continuing. This means that until a response is returned by the API, your application will not execute any further, which could be perceived by the user as latency or performance lag in your app. Making an API call synchronously can be beneficial, however, if there is code in your app that will only execute properly once the API response is received.

Chamada sincrona Globalcode – Open 4 education

Chamada assincrona Asynchronous calls do not block (or wait) for the API call to return from the server. Execution continues on in your program, and when the call returns from the server, a "callback" function is executed Globalcode – Open 4 education

Controle de Fluxo Consistência Eventual e Transacional Globalcode – Open 4 education

Consistência Transacional Consistency is one of the four guarantees that define ACID transactions; however, significant ambiguity exists about the nature of this guarantee. It is defined variously as: The guarantee that any transactions started in the future necessarily see the effects of other transactions committed in the past The guarantee that database constraints are not violated, particularly once a transaction commits The guarantee that operations in transactions are performed accurately, correctly, and with validity, with respect to application semantics Globalcode – Open 4 education

Consistência Eventual consistency is a consistency model used in distributed computing to achieve high availability that informally guarantees that, if no new updates are made to a given data item, eventually all accesses to that item will return the last updated value. Eventual consistency, also called optimistic replication, is widely deployed in distributed systems, and has origins in early mobile computing projects Globalcode – Open 4 education

Controle de Fluxo Processamento em lote(batch) Globalcode – Open 4 education

Processamento em lote Benefícios do Processamento em Lote: Acelera o processamento de informações em massa; Busca evitar a ociosidade do computador, não necessitando de supervisão ou interação do usuário; Permite o uso de diferentes prioridades para trabalhos interativos e não interativos; Executa apenas uma vez o programa para processar grandes quantias de dados, reduzindo a sobrecarga de sistema.

Controlede Fluxo Pub/Sub Globalcode – Open 4 education

Pub/Sub Also called Observer and Observer-Observable. Use this pattern to notify event handlers (Subscribers or Observers) when some interesting object (Publisher or Observable) changes state. Globalcode – Open 4 education

Pub/Sub Globalcode – Open 4 education

Controle de Fluxo Compressão, Criptografia e Payload Globalcode – Open 4 education

Compressão Dependendo do tipo de dado e compressão, o ganho de performance na transferência pode chegar a 80% de ganho de performance Dificulta a análise de logs, a menos que seja incluído um identificador único para que seja possível rastrear a mensagem no pipeline de processamento da menssagem Globalcode – Open 4 education

Criptografia Garante a segurança da informação dentro do pipeline de processamento da mensagem Dificulta a análise de logs, a menos que seja incluído um identificador único para que seja possível rastrear a mensagem no pipeline de processamento da menssagem Globalcode – Open 4 education
