- - - - Alta Disponibilidad minimizar las interrupciones que afecten la continuidad del negocio
      - Fault Tolerance busca crear arquitecturas que no tengan un punto unico de falla, por medio de la redundancia y el balanceo de cargas. Se apoya en conceptos como maquinas virtuales escalables, Fault Domains y Update Domains
      - Disaster recovery es la capacidad de recuperarse de un desastre de la forma mas rapida posible
      - Scalability es la capacidad de aumentar los recursos de forma horizontal (agregando mas servidores o VMs) o de forma vertical (agregando mas CPU, mas RAM y mas disco a un unico servidor). La diferencia con Elasticity es que este ultimo es automatico.
      - Elasticity es la capacidad para aumentar o disminuir los recursos de acuerdo a la demanda, y hacerlo de forma automatica
    - - Agility — Cloud allows the business to deliver IT system to customers faster. The machines in the cloud are ready for cloud users to spin up when they need and shut down when they are not required.
      - Economies of scale — Cloud is a shared pool of machines and services. As the number of customer grows, the cloud providers can lower the cost or increase quality of the services.
      - Capital Expenditure (CapEx) vs Operational Expenditure (OpEx) — Building a data center requires large capital investment for hardware as well as the facility. A data center will also require ongoing electricity and staffs cost for operation. By using cloud, the capital expenditure for building a data center is not required.
      - Consumption-based model (pay-as-you-go) — The cloud users only pay for what they need, by the duration they need.
  - - - Migrating workloads. Typically, IaaS facilities are managed in a similar way as on-premises infrastructure and provide an easy migration path for moving existing applications to the cloud.
      - Test and development. Teams can quickly set up and dismantle test and development environments, bringing new applications to market faster. IaaS makes scaling development and testing environments, fast and economical.
      - Storage, backup, and recovery. Organizations avoid the capital outlay and complexity of storage management, which typically requires skilled staff to manage data and meet legal and compliance requirements. IaaS is useful for managing unpredictable demand and steadily growing storage needs. IaaS can also simplify the planning and management of backup and recovery systems.
    - - Development framework. PaaS provides a framework that developers can build upon to develop or customize cloud-based applications. Just like Microsoft Excel macro, PaaS lets developers create applications using built-in software components. Cloud features such as scalability, high-availability, and multi-tenant capability are included, reducing the amount of coding that developers must do.
      - Analytics or business intelligence. Tools provided as a service with PaaS allow organizations to analyze and mine their data. They can find insights and patterns, and predict outcomes to improve business decisions such as forecasting, product design, and investment returns.

      - AWS
      - Google Cloud
      - Oracle Cloud
- - - - Azure Functions, which can execute code in almost any modern language. Escala en demanda de forma automatica y solo ejecuta una sola funcion desencadenada por un evento en particular. Es state-less lo que significa que se reinicia a cero una vez concluida su objetivo, si se desea un funcionamiento con estado se puede asociar un storage account. Tiene las siguientes caracteristicas: Normalmente Stat-less, construccion a base de codigo, monitoreo con Azure Application Insight, puede ser ejecutada tanto en la nube como local.
      - Azure Logic Apps, which are designed in a web-based designer and can execute logic triggered by Azure services without writing any code. Es muy similar a Azure Functions con la diferencia de que desencadena todo un workflow. Tiene las siguientes caracteristicas: Statefull, Monitoreo por Azure portal y Log Analitycs, solamente corre en la nube.
      - Event Grid allows you to easily build applications with event-based architectures. It's a fully managed, intelligent event routing service that uses a publish-subscribe model for uniform event consumption. Event Grid has built-in support for events coming from Azure services, such as storage blobs and resource groups. You can use Event Grid to support your own non-Azure-based events in near-real time, using custom topics. You can use filters to route specific events to different endpoints, and ensure your events are reliably delivered.

    - - Azure Containers Instances (ACI)
        Azure Container Instances (ACI) offers the fastest and simplest way to run a container in Azure. You don't have to manage any virtual machines or configure any additional services. It is a PaaS offering that allows you to upload your containers and execute them directly with automatic elastic scale.
      - Azure Kubernet Services (AKS)
        The task of automating, managing, and interacting with a large number of containers is known as orchestration. Azure Kubernetes Service (AKS) is a complete orchestration service for containers with distributed architectures with multiple containers.
    - - Web Apps
        App Service includes full support for hosting web apps using ASP.NET, ASP.NET Core, Java, Ruby, Node.js, PHP, or Python. You can choose either Windows or Linux as the host operating system.
      - API apps
        Much like hosting a website, you can build REST-based Web APIs using your choice of language and framework. You get full Swagger support, and the ability to package and publish your API in the Azure Marketplace. The produced apps can be consumed from any HTTP(S)-based client.
      - Web Jobs
        Web Jobs allows you to run a program (.exe, Java, PHP, Python, or Node.js) or script (.cmd, .bat, PowerShell, or Bash) in the same context as a web app, API app, or mobile app. They can be scheduled, or run by a trigger. WebJobs are often used to run background tasks as part of your application logic.
      - Mobile app back-end
        Use the Mobile Apps feature of Azure App Service to quickly build a back-end for iOS and Android apps.
  - - - Azure Application Gateway
        If all your traffic is HTTP, a potentially better option is to use Azure Application Gateway. Application Gateway is a load balancer designed for web applications. It uses Azure Load Balancer at the transport level (TCP) and applies sophisticated URL-based routing rules to support several advanced scenarios.

  - - - Azure Marketplace
        The Azure Marketplace is often where you start when creating new resources in Azure. The Marketplace allows customers to find, try, purchase, and provision applications and services from hundreds of leading service providers, all certified to run on Azure.
        The solution catalog spans several industry categories, including but not limited to open-source container platforms, virtual machine images, databases, application build and deployment software, developer tools, threat detection, and blockchain. Using Azure Marketplace, you can provision end-to-end solutions quickly and reliably, hosted in your own Azure environment. At the time of writing, this listing included over 8,000 listings.
      - Azure Advisor Finally, the Azure Advisor is a free service built into Azure that provides recommendations on high availability, security, performance, operational excellence, and cost. Advisor analyzes your deployed services and looks for ways to improve your environment across those areas. You can view recommendations in the portal or download them in PDF or CSV format.
  - - - Regiones
        A region is a geographical area on the planet containing at least one, but potentially multiple datacenters that are nearby and networked together with a low-latency network. Azure intelligently assigns and controls the resources within each region to ensure workloads are appropriately balanced.
        
        Zona de disponibilidad
        Availability Zones are physically separate datacenters within an Azure region.
        Each Availability Zone is made up of one or more datacenters equipped with independent power, cooling, and networking. It is set up to be an isolation boundary. If one zone goes down, the other continues working. Availability Zones are connected through high-speed, private fiber-optic networks.
        
        Pares de regiones
        Each Azure region is always paired with another region within the same geography (such as US, Europe, or Asia) at least 300 miles away. This approach allows for the replication of resources (such as virtual machine storage) across a geography that helps reduce the likelihood of interruptions due to events such as natural disasters, civil unrest, power outages, or physical network outages affecting both regions at once. If a region in a pair was affected by a natural disaster, for instance, services would automatically fail over to the other region in its region pair.
    - - Performance Tarhet
        An SLA defines performance targets for an Azure product or service. The performance targets that an SLA defines are specific to each Azure product and service. For example, performance targets for some Azure services are expressed as uptime guarantees or connectivity rates.
      - Uptime and Connectivity Guarantees
        A typical SLA specifies performance-target commitments that range from 99.9 percent ("three nines") to 99.999 percent ("five nines"), for each corresponding Azure product or service. These targets can apply to such performance criteria as uptime or response times for services.
      - Service Credits
        SLAs also describe how Microsoft will respond if an Azure product or service fails to perform to its governing SLA's specification.
