    AFLS Structure OnPremise Environments

    The Aranda Field Service architecture is an application distributed in the following components:


    App Service

    It is a Microsoft Azure cloud service that allows you to build, host, and scale web and mobile applications quickly and easily. In the App Services we have the deployment of the AFLS Web console, the AssistMe client console and the AFLS APIs.

    App Service Plan

    Defines a set of compute resources for a web application to run.

    Aranda Push Gateway Central

    Manage the push notification service, technology that apps use to send messages to users.

    Blob Storage

    A storage service for unstructured data, such as text or binary data, that is designed to meet the scale, security, and availability needs of mobile, web, and cloud-native application developers, it is used in AFLS to store attachments and import result files.

    Customers

    Person or company that acquires the services configured by a company, for the management of work orders with AFLS. Taking into account the role assigned to the customer, they are allowed to access the Web console or the AssistMe console from the Browser, they can make requests through the available APIs or they can access the mobile console on Android or iOS. Note: The customer must publish the services to the internet.

    Database Server

    A server that uses a database application and provides database services to other computer programs or computers, as defined by the client-server model.

    Database Tenant

    SQL Server database, contains all the tables and information corresponding to Aranda’s products

    Federated Identity (SAML)

    It allows you to delegate user authentication to a third-party provider, improving the user experience in your application.

    Firewall

    A security barrier that controls network traffic, allowing or blocking access to a computer network according to predefined rules to prevent unauthorized access and protect against threats.

    LDAP Server

    Allows you to store and retrieve information about users, groups, or objects on an active directory server. Note: The server port may vary depending on the client’s configuration.

    Mail Server

    It is a server used to receive, send, and manage emails.

    Note: The server port may vary depending on the client’s configuration.

    Microsoft Azure

    A pool of resources where Aranda products and services are hosted in the Azure cloud.

    Port

    It is an interface through which different types of data can be sent and received.

    Server

    It is a computer that allows you to process information and programs. They are designed to support heavier workloads and/or be always available for users to access their resources, be it software, data, etc. On the server we have the deployment of the AFLS Web console, the AssistMe client console and the AFLS APIs, the installation of the services is also carried out.

    Storage Account

    Azure cloud storage account, used in AFLS to store attachments and import result files.

    Virtual Directory

    It is a link to an existing physical directory. For AFLS we have four virtual paths and they are as follows:

    • /AFLS • /AssistMe • /AssistMe/ASSISTMEWS • /AFLSAPI

    Virtual Machine

    A virtual machine (VM) is a virtual environment that functions as a virtual computer system with its own CPU, memory, network interface, and storage, but is built on a physical hardware system.

    VPN

    It is a technology that establishes a secure, encrypted connection over a public network, such as the Internet, allowing users to securely access and share data over a remote connection.

    Web Application Firewall (WAF)

    Advanced security for Azure-hosted websites keeps applications secure and productive.

    Windows Services

    It is a computer program that works in the background. We have four important services:

    Service Description
    Aranda AFLS AssignmentEngine Services The AFLS assignment engine resembles the operation of a neural network, where it has inputs with initial weights which are decisive when choosing the best specialist to attend to a work order.
    The relationship of the incoming parameters in the mapping engine is:
    - Execution time for each work order (DmCost)
    - Position in coordinates (DmDistance)
    - List of skills required for the service (DmSkill)
    - Work Order Attention Time Limit (DmSLA)
    - Distribution of the order of care to support work orders by specialists (DmDistribution)

    Note: Port 1605 is used
    Aranda License Windows Services Administrator and validator of licenses for Aranda applications. There can only be a single licensing service running on the server
    Aranda Worker Windows Services Scheduled task executor. Tasks are specific actions that must be performed, some scheduled or at the time of making some AFLS configuration are in table AFW_TASKS (Start with id 34), those that require programming are displayed in the AFW_SCHEDULER table with a specific frequency, execution time of the same, date of last execution and date of next execution.
    How the process works between Scheduler and Worker:
    - Scheduler: Schedule and send tasks to the Worker.
    - Worker: Executes and leaves execution traces in AFW_WORKER_LOG.

    Note: The Worker has the ability to queue requests since multiple tasks can be sent and executed at the same time.
