  Como criamos sistemasmais robustos, mais resilientes, mais flexíveis e muito mais capazes de responder às exigências de hoje em dia?
• 6.
  Precisamos de sistemasque irão: ● Reagir a eventos (Event-Driven) ● Reagir a carga (Scalable) ● Reagir a falhas (Resilient) ● Reagir a usuários (Responsive)

  Reactive Programming “Readily responsiveto a stimulus”

  O que sãosistemas Reativos? Sistemas criados como Reativos são muito mais flexíveis, desacoplados e escaláveis. Isso os torna mais fáceis de desenvolver e manter. São mais tolerantes a falhas e quando elas ocorrem são tratadas com elegância ao invés de desastre. Sistemas Reativos são responsivos, dando aos usuários feedbacks mais interativos.

  Reactive Manifesto
• 10.
  Message-Driven “Reactive Systems relyon asynchronous message-passing” Share Mutable State Immutability Avoid Block Asynchronous
• 11.
  Some t ls ●Actors ● Agents ● Future/Dataflow ● Reactive Extensions (Rx)
• 12.
  Elastic “Capable of beingeasily expanded or upgraded on demand” Distribuited systems Availability Scalability Asynchronous
• 13.
  “Almost” no limitto scalability. Shared Nothing Assynchronous communication Location Transparency Loose Coupling
• 14.
  Resilience “The ability ofa substance or object to spring back into shape.” “The capacity to recover quickly from difficulties.” Failure recover Manage failure locally Avoid cascading failures Isolate the failure
• 15.
  Responsive “Quick to respondor react appropriately” Latency consistent Batching Back Pressure Reactive Request
