Chapter 1: IntroductionChapter 1: IntroductionToday's computing landscape is no longer confined to a desktop, device, server, or data center.Applications are being moved from the desktop to multiple devices, network edge connections, and toon-premises, public and hybrid cloud services. With RAD Server and RAD Studio, you can build solutionsthat cover a wide spectrum of your company's (and customer’s) computing needs and businessrequirements.This e-book will show you how to quickly design, build, debug, and deploy services-based multi-tierapplications using RAD Server’s REST-based API hosting engine, components and technologies that areavailable in RAD Studio Enterprise and Architect editions.The computers, software and devices used in creating this technical paper include RAD Studio 10.3.1 RioEnterprise Edition, InterBase 2017 Server, Dell desktop running Windows version 10, Dell notebookrunning Windows version10, Dell notebook running Ubuntu version16.04 LTS, MacBook Pro runningmacOS 10.14 Mojave, iPhone running iOS version 12.1.4 and Nexus 7 running Android version 6.0.1What You’ll LearnAfter reading this e-book, you’ll have learned: RAD Server’s application development tips and techniquesRAD Server’s platform requirementsHow to build and test your first RAD Server applicationsHow to deploy your RAD Server applications to Windows IIS and Linux ApacheNew RAD Server features in RAD Studio 10.3.1 RioHow to build client applications using Delphi, C and JavaScript to access your RAD ServerendpointsWhat samples and application templates are available for RAD Server to get you startedWhere to find additional references, resources, videos, blog posts and moreRAD Server OverviewEmbarcadero’s RAD Server provides a turn-key application foundation for rapidly building and deployingservices-based applications using Delphi and C Builder. RAD Server supports the REST(Representational State Transfer) protocol with JSON (or XML) parameter passing and return results. Youcan publish APIs, manage users and devices that are connected to the RAD Server, capture analyticsabout the use and users of applications, connect to local and enterprise databases using the FireDACcomponents and connect with Internet of Things (IoT) devices. RAD Server also supports userauthentication, push notifications, geolocation, and data storage.6(Copyright 2019 Embarcadero Technologies, Inc.)
Chapter 1: IntroductionThroughout the RAD Server documentation, source code, and in this technical paper, you’ll seereferences to EMS (Enterprise Mobility Services). EMS was the original name for the product,technologies, components and wizards that are now included the RAD Server product.Figure 1: RAD Server: the Service Tier for a Multi-TierArchitectureWith RAD Server’s wizards, components, and tools you can quickly develop new middleware and backend applications or migrate your existing Delphi and C Builder client/server applications to a RADServer based application to run on a server or in the cloud. You can publish your endpoints for REST callsfrom desktop, mobile, console, web and other types of applications. RAD Server comes with a full set oftools, components, database connectivity and interfaces that you will rely upon in building your serviceapplications.RAD Server applications can be deployed on top of Microsoft Windows IIS and Apache web servers, andyou can deploy your Delphi-based services to Linux Intel 64-bit servers.Figure 2: Develop and Test REST endpoints, LocationTracking and IoT Edgeware7(Copyright 2019 Embarcadero Technologies, Inc.)
Chapter 1: IntroductionBuilding RAD Server based applications – Seven Key AspectsTo build RAD Server based applications, the diagram below guides developers through seven aspects anddevelopment phases.Figure 3: Multi-Tier Development Made EasyTo start, create your server REST/JSON API-based endpoints (you can also use XML instead of JSON ifrequired). Next extend the endpoints by integrating a wide range of databases, cloud services, IoTdevices, and other technologies.You can add more application endpoints to users and create API access control rules. You can write codethat leverages RAD Server’s built-in secure data store to keep track of persistent data. You can create usergroups, add users via console portal and import, or authenticate users via LDAP-based API services.After you have developed and debugged your applications, you can host RAD Server applications on aprivate on-premises Windows and Linux servers. You can also migrate your applications to cloud systemslike Amazon AWS, Microsoft Azure, Google, and other cloud providers.After your application is put into production, you can manage access to your APIs, control users access,and analyze the utilization of your endpoint API activity with built-in application management interfaces.Finally, you can build desktop, mobile, Web, console, and other application types supported by RADStudio. You can also build modern Web client applications using Sencha ExtJS’s set of components or useother tools and programming languages to build client applications that support your RAD Serverapplication’s REST/JSON functionality.8(Copyright 2019 Embarcadero Technologies, Inc.)
Chapter 1: IntroductionRequirements for Building RAD Server ApplicationsThe following sections contain the product and technical requirements for building, testing, and deployingRAD Server applications. Unless otherwise noted, “RAD Studio” and the IDE apply to the RAD Studio,Delphi, and C Builder products.Using the RAD Studio IDEA RAD Studio Enterprise or Architect Edition version 10.1 Berlin or later with a commercial license isrequired to build RAD Server applications. This white paper was written and tested using a commercialversion RAD Studio version 10.3.1 Rio Enterprise Edition. The trial edition of RAD Studio Enterprise canbe used for 30 days, for development and testing. The trial edition does not support deployment to aproduction server.RAD Server Testing and Deployment LicensesTo test RAD Server applications, RAD Studio includes a 5-user developer license. Beginning with version10.2 Release 2, RAD Server deployment licenses are included in Enterprise and Architect commercialeditions of RAD Studio. These commercial editions include a single-site deployment license for RADServer. RAD Studio 10.2.3 Architect edition includes a multi-site deployment license for customers whoare on active Update Subscription.RAD Server requires an InterBase 2017 encrypted database as part of deploying your applications in aProduction Environment. You will need to use a valid RAD Server license to install this version ofInterBase.FireDAC Supported DatabasesIf your RAD Server application needs to connect with SQL databases, MongoDB, or through an ODBCdatabase bridge, you can use FireDAC with the following database systems and versions.DatabaseSupported VersionsAdvantage Database Server8.0 and higherSybase SQL Anywhere5.0.0 and higherIBM DB2 Server8.1 and higherFirebird1.5 and higherInterBase Server6 and higherInterBase Lite / InterBase ToGo6 and higherInformix Server8 and higher.
