    rights reserved. S U M M I T 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 Layers arn:aws:lambda:region:accountId:layer:shared-lib Lambda Layers arn:aws:lambda:region:accountId:layer:shared-lib:2 Lambda Layers arn:aws:lambda:region:accountId:layer:shared-lib:3

    2014 2015 2016 2017 2018 2019 GENERACIÓN 2 • Servidores balanceados Activo-Pasivo • Cambio a Angular.js y APIs REST • Alojador local • Arquitectura sencilla • Pocos componentes software • Desárrollo ágil • Desarrolladores de frontend y backend • Poco escalable y resiliente • Baja productividad (<50%) • Despliegues lentos • Gestión muy manual Gen 4 cloud Gen 2 cloud Gen 3 cloud • Único servidor en alojador local • Aplicación monolítica • Desarrollo basado en GWT Gen 1 cloud
  51. Smart Information for a moving world! • Se popularizan metodologías

    DevOps • Migración a AWS • Breaking the monolith: Primeros micro servicios • Necesidad de almacenamiento masivo económico (Amazon S3 vs. Openstack Swift) • Agilidad en el aprovisionamiento de servicios • Servicios gestionados (Amazon RDS) • Muchas instancias AWS Elastic Beanstalk (hasta 120) • Incertidumbre de seguridad: gestión de Security Groups complicada • Instancias con poco uso (productividad del 60%) Motivos del cambio GENERACIÓN 3 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 Gen 1 cloud Gen 4 cloud Gen 2 cloud Gen 3 cloud AWS Elastic Beanstalk Amazon S3 Amazon DynamoDB Amazon Elasticsearch Service AWS Lambda AWS IoT Core Amazon CloudWatch Amazon SQS Amazon SNS

  55. Smart Information for a moving world! • Despliegues muy ágiles

    y automatizables • Misma arquitectura y misma gestión en on-premises y en AWS • Ligero ahorro de costes (10%). Con reserva de instancias hasta 50% de ahorro • Alta productividad de la infraestructura (>80%) • Alta escalabilidad y auto-escalable • Alta resiliencia • Alta gestionabilidad (de 120 a 20 instancias) GENERACIÓN 4
  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
