   Best practices for modern application development
   • Enable experimentation by creating a culture of ownership
   • Componentize applications using microservices
   • Update applications and infrastructure quickly by automating the release pipeline
   • Model and provision application resources using infrastructure as code
   • Simplify infrastructure management with serverless technologies
   • Improve application performance by increasing observability
   • Secure the entire application lifecycle by automating security

    Lambda Layers
    Lets functions easily share code: Upload layer
    once, reference within any function
    Promote separation of responsibilities, lets
    developers iterate faster on writing business logic
    Built in support for secure sharing by ecosystem

    Using Lambda Layers
    • Put common components in a ZIP file and
    upload it as a Lambda Layer
    • Layers are immutable and can be versioned
    to manage updates
    • When a version is deleted or permissions to
    use it are revoked, functions that used it
    previously will continue to work, but you
    won’t be able to create new ones
    • You can reference up to five layers, one of
    which can optionally be a custom runtime
    Lambda

    Lambda permissions model
    Fine grained security controls for both
    execution and invocation:
    Execution policies:
    • Define what AWS resources/API calls can this
    function access via IAM
    • Used in streaming invocations
    • E.g. “Lambda function A can read from
    DynamoDB table users”
    Function policies:
    • Used for sync and async invocations
    • E.g. “Actions on bucket X can invoke Lambda
    function Z”
    • Resource policies allow for cross account
    configst access

56. Smart Information for a moving world!
    ● Motivación del cambio a AWS
    ○ Necesidad de disponer de un almacenamiento masivo
    ○ Servicios gestionados
    ○ Mayor autonomía y agilidad en la gestión de instancias
    ● Por qué AWS:
    ○ Líder del sector
    ○ Disponibilidad de tutoriales, documentación y formación
    ○ Red de empresas asociadas: consultores, asesoramiento
    ● Logros obtenidos:
    ○ Romper monolito e implementar arquitectura de micro servicios
    ○ Pasar de 120 instancias (small-medium) EC2 a 20 (xlarge)
    ○ 5 despliegues por semana (limitado por los recursos de desarrollo)
    ○ Migración de Elastic Beanstalk a Kubernetes, reducción de costes del 10% (depende de uso)
    ○ Con reserva de instancias, reducción de costes del 50%
    ○ Arquitectura escalable, resiliente y optimizado en costes
    CONCLUSIONES
