With AWS WorkSpaces, organizations can have desktops delivered securely and cost-effectively, thanks to AWS DaaS (Desktop as a Service). WorkSpaces from Amazon allow you to deploy desktops as virtual private clouds (VPCs) and provide each desktop with an assigned storage directory. As a result, desktop users can easily be authenticated.

What Is AWS DaaS?

Amazon WorkSpaces is a managed DaaS service available through Amazon Web Services”(AWS)”. You can create and access desktops running Linux or Microsoft Windows wherever you are. Using it, you can add and flexibly remove users while paying only for resources that you utilize.

Amazon WorkSpaces Features

Workspace offers noteworthy features, including licensing flexibility, permissions management, and storage capabilities. In contrast to traditional on-premises virtual desktop infrastructure (VDI) solutions, Amazon WorkSpaces provides a fully managed service so you don’t have to worry about deploying, managing, and procuring a complex environment. You can deliver high-quality applications, and portable desktops, to your users on the device they prefer through Amazon WorkSpaces.

.You must have your own license.
Bring your own license (BYOL) options are available in Amazon WorkSpaces for Windows, which lets you leverage your existing virtual desktop investments. If you meet Microsoft’s requirements, you can save up to $4 per workspace each month with this option. To benefit from BYOL, you must provision two hundred or more workspaces in your region each month.

.Active Directory and RADIUS integration
Many organizations use an Active Directory (AD) for managing identities and permissions. AWS integration allows you to move policies and roles from your current system to Amazon WorkSpaces without having to recreate them. For connections between AD and AWS Directory Service for Microsoft AD (Enterprise Edition), either the AWS Directory Service AD Connector or a trust relationship can be configured. Your existing configurations and Group Policies will continue to work once you have connected. Multi-factor authentication (MFA) can be supported using existing RADIUS servers.

.Persistent storage
Each bundle you choose determines how much storage is available for your workspaces. Persistent storage is available for every user volume that is connected to a workspace, no matter how much storage it contains. When the user reconnects, any data that is stored on their user volume is backed up to S3. A managed service for content management, Amazon WorkDocs Drive, is another option for storing documents. Using this driver, you can simulate local storage by mounting it in Amazon WorkSpaces. With WorkDocs, you can access documents through Windows File Explorer and access them the same way you would if they were local files. WorkDocs synchronizes all files to the WorkDocs hub so that they can be accessed on-demand.


AWS WorkSpaces Architecture

Amazon WorkSpaces desktops are deployed in the virtual private cloud (VPC) and are housed in a directory where deployments and user data can be stored and managed. The AWS Directory Service supports Microsoft Active Directory (AD), AD Connector, and Simple AD for managing these directories. Your users can be authenticated by choosing a directory. Your directory receives the credentials from the authentication gateway that users utilize to access their workspaces. Streaming gateways are used to stream the desktop to the user client if the user has been authenticated. Two elastic network interfaces are associated with each desktop. Interfaces like these are used to connect desktops to networks, manage desktops, and stream desktop contents to clients. Your primary network interface (used to connect your directory to the Internet) has an assigned IP address assigned by the VPC, and it matches the subnets of your directory. Modifying the security groups associated with this primary interface gives you access control over your VPC resources.

Benefits of Amazon WorkSpaces

Organizations can gain several benefits from using Amazon WorkSpaces in addition to optimizations for usage scenarios. In addition to simplified delivery, increased security, and flexible deployment, these benefits also come with reduced costs.

.Easy desktop delivery
Reduced responsibilities and workload allow IT teams to focus on more important tasks with desktop management. Services can be dynamically modified as organizational requirements and applications change.

.According to usage patterns and frequency estimates, cost efficiency
Services can be billed hourly or monthly. In addition, you can choose between multiple resource packages, so you will not be overcharged.

The service is compatible with Amazon Virtual Private Network (VPN) and comes with built-in encryption. IAM allows administrators to manage user permissions to ensure that only approved data can be accessed and that inappropriate data transfers are not permitted.

.Flexible deployments
IAM can be deployed across a wide range of devices. Chrome and Firefox browsers can also be used to deploy desktops. Amazon WorkSpaces allows you to create persistent and ephemeral desktops, so you can provide desktops that meet a variety of requirements.


What is Desktop as a Service (DaaS)?

Desktop as a Service (DaaS) is a cloud computing offering that allows a service provider to deliver virtual desktops through the Internet, licensed per user. For small businesses unable to create their virtual desktop infrastructure because it is too expensive or resource-intensive, the VDI provider provides backend management services. Maintaining, restoring, updating, and storing data are common aspects of this management. Security and desktop applications may also be managed by cloud service providers, or users may manage these aspects of their own cloud services. You can choose between persistent and non-persistent desktops in DaaS.

Persistent desktop
A persistent desktop is one that users can customize and save so it will look the same no matter what time of day they log on. Desktops with persistent data require more storage than desktops without persistent data so they can be more expensive.

Non-persistent desktop
In a non-persistent desktop, the desktop is erased each time the user logs out. Users access the services by logging in.

Depending on the cloud provider, customers may be able to choose between these two options; workers with specific needs could access a persistent desktop, while occasional or temporary workers could access a non-persistent desktop.

Advantages of Desktop as a Service (DaaS)

Compared with a traditional desktop model, desktop as a Service (DaaS) has clear advantages. Active end users can be deployed or decommissioned more quickly and inexpensively with DaaS.

.Active users can be deployed and decommissioned faster
It requires only that a new device be connected to the desktop, which is already configured. DaaS can save time and money for seasonal businesses that constantly experience fluctuations in demand or employee numbers.

.Reduced downtime for IT supports
As a result of desktop as a Service, IT support can be provided remotely to employees, reducing downtime.

.Cost savings
Due to the lower requirement for computing power, the devices that run DaaS are less expensive and use less energy.

.Increased device flexibility
Cloud-based desktops support a variety of operating systems and device types, allowing users to bring their own devices to work and shift the burden of supporting their desktops across multiple devices to the cloud computing provider.

.Enhanced security
With DaaS, there is significantly less security risk since data is stored in the data center. You can simply disconnect a stolen laptop or mobile device from the service if it has been stolen. Data does not reside on the stolen device, so there is minor risk of a thief accessing sensitive information. DaaS environments also make it easier to install security patches and updates since all desktops can be updated at the same time from a remote location.

Working principle of DaaS

Desktop as a Service (DaaS) entails hosting infrastructure, network resources, and storage on the cloud, where a virtual desktop is streamed to users’ devices. Users have access to the desktop’s data and applications using an internet browser or other program. The subscription-based model allows organizations to purchase as many virtual desktops as they need. Historically, graphics-intensive applications have been challenging to implement with DaaS since desktop applications stream over the Internet from a centralized server. Even applications requiring an enormous amount of computer power, such as computer-aided design (CAD), can now be run on DaaS thanks to the advent of innovative technology. As a cloud computing vendor, the desktop-as-a-service provider takes care of data storage, backup, security, and upgrade functions. Customers manage their own virtual desktop images, applications, and security, except for desktop management services that are included in the subscription. Back-end infrastructure costs and maintenance are managed by the vendor.

An IT administrator can move a virtual machine running on one server to another in just a few seconds if the workload gets too heavy on one server, so graphics-accelerated or GPU-accelerated applications can continue to run without interruption. Applied to any industry that requires multimedia production, 3D modeling, simulations, or high-end graphics, GPU-accelerated Desktop as a Service (GPU-DaaS) can be helpful. All these industries can benefit from this technology, including engineering, broadcasting, and architecture.

Why Desktop as a Service?

Compared to traditional models, desktop as a Service (DaaS) offers streamlined management, increased flexibility, and lowered cost of ownership. DaaS allows businesses to create a digital workspace quickly and easily for remote workers and flexible devices. Logging into a virtual desktop is possible from anywhere, through a variety of devices, and the desktop will look exactly as when it was last viewed from a different location. An internet connection is all that is required for the entire process. Data that lives in a centralized, remote location can be continuously backed up – users do not need to worry about managing backups on their own or having data at home but not at work.
