Remote Application Server Software: A Guide

An application server software is a program that hosts applications. Application server software sits between the web server and database server, acting as a go-to solution for users that want to install, operate, and host applications and associated services.

It offers several compelling benefits, including enhanced security to applications, improved fault tolerance, and streamlined management of programs, among others. Find out more about application servers and how Parallels® Remote Application Server (RAS) is key to ensuring the security of dynamic remote working solutions in this article.

Definition of Remote Application Server Software

Remote application server software runs in a datacenter and facilitates the installation, operation, and delivery of applications and desktops to end users in an organization. Organizations can use application servers in various ways, including running web applications, monitoring and distributing software updates, and processing data from another server.

An application server can also host a hypervisor, allowing it to run multiple virtual machines (VMs). Organizations can then deliver virtual applications and desktops—residing within the VMs—to heterogeneous end-user devices without requiring them to install such programs on the actual host machines.

The terms web server and application server are sometimes used interchangeably, even though they carry different meanings. A web server delivers static web content such as hypertext markup language (HTML) pages, files, images, and videos. This is primarily in response to hypertext transfer protocol (HTTP) requests that emanate from a web browser.

Usually, most web servers support plugins for scripting languages such as Active Server Pages (ASP), Jakarta Server Pages (JSP), Hypertext Preprocessor (PHP), and Perl. Web servers use these plugins to generate dynamic content based on server-side logic.

While an application server can also deliver web content, its primary responsibility is to facilitate interaction between clients and the business logic. Through business logic, an application server transforms data into dynamic content such as transaction results, decision support, and real-time analytics to support the functionality of applications.

Application servers also allow applications to leverage services such as clustering, load balancing, reverse proxy, and redundancy—services that enhance the reliability and performance of workloads.

Benefits of Using Application Server Software

Below are three advantages of using application servers:

Models for Application Server Software Deployment

There are four models under which you can deploy an application server software:

1. On-premises deployment

Under this model, the application server software gets deployed in-house and within the organization’s IT infrastructure. The server runs under the supervision of in-house IT teams while data remains under the organization’s control. IT teams also maintain the application server and all its related processes.

2. Public cloud deployment

This is a model where public cloud service providers (CSPs) provide cloud-based services such as software as a service (SaaS), platform as a service (PaaS), or infrastructure as a service (IaaS) to organizations on a pay-as-you-go pricing scheme. An organization can deploy its application server software using these services without hosting the underlying infrastructure in its own datacenters.

3. Hybrid cloud deployment

A hybrid cloud model combines on-premises with public cloud deployment, allowing the application server software and its underlying data to be moved between them as costs and needs change. Using this model enables the organization to derive the same security measures available within its existing, on-premises IT infrastructure while benefiting from agility and flexibility in public clouds.

4. Hyperconverged infrastructure deployment

Deploying an application server on public clouds requires specialized IT skills that may diverge from in-house IT teams, increasing the specialization in an already highly siloed enterprise. Besides, deploying some applications in public clouds may create security challenges that an organization may want to avoid.

Deploying the application server software in a hyper-converged infrastructure (HCI) environment allows the organization to derive the benefits of public clouds while building private clouds or on-premises deployments. You can also extend HCI deployments into public clouds and create hybrid cloud environments, allowing the application server to be managed with the same tools that simplify data migration between the two domains.

Parallels RAS supports all the above-mentioned deployment models. You can install it on-premises or in public clouds such as Azure or Amazon Web Services (AWS). It also supports HCI deployments such as Nutanix Acropolis, Scale Computing HC3, and HPE.

Parallels RAS: Remote Application Server Software

Parallels RAS is a comprehensive application delivery and desktop virtualization solution. Organizations can use Parallels RAS to deliver virtual applications and desktops remotely, allowing employees to access such resources from any endpoint at any time. The platform empowers organizations to centralize their IT infrastructures, which reinforces security.

Companies can also leverage Parallels RAS features such as granular permission policies, multi-factor authentication (MFA), transport layer security (TLS), and Federal Information Processing Standards (FIPS) 140-2 encryption to improve security. Also, Parallels RAS has out-of-the-box high availability load balancing (HALB) that IT teams can use to distribute workloads among remote desktop servers.

Besides security and HALB features, Parallels RAS also provides numerous compelling benefits such as:
