Virtual desktop technologies have continued to mature over the years as enterprises keep looking for ways to lower costs associated with maintaining fleets of complex, traditional desktop infrastructure. DaaS (Desktop-as-a-Service) and VDI (Virtual Desktop Infrastructure) are the two main virtual desktop solutions in the market today.
DaaS is a virtual desktop infrastructure that is hosted and managed in the cloud by a third-party provider. The service provider is responsible for managing all the underlying infrastructure for you. DaaS is essentially VDI that is someone else's problem.
Despite being the newer technology, Gartner has noted that DaaS now rivals traditional VDI in terms of feature sets. The DaaS market is expected to grow at an impressive 44% CAGR to reach nearly $1.3 billion by 2020. Increasing data generation across industry verticals such as healthcare, BFSI, retail and public has been rapidly escalating due to the ongoing digital transformation and deeper investments in cloud, mobility and analytics. This, coupled with ever-rising costs of on-premise storage infrastructure, has led to a pressing need to cut down on data management costs. The growing need for seamless data management is another key driver augmenting demand for DaaS solutions.
If you are currently using traditional desktop infrastructure or VDI and are evaluating a DaaS solution, here are the top 5 reasons why you should make the move.
1) Low entry costs
DaaS is essentially a cloud subscription service, meaning you don't need to buy any hardware to deploy. With entry-level costs of about $35 per user/ month, many businesses are likely to realize significant cost savings particularly in a BYOD scenario. In contrast, VDI requires the purchase and maintenance of expensive servers and related hardware.
2) Agility and scalability--Buy only what you need
DaaS service providers charge according to the number of users. Your monthly subscription is therefore directly proportional to the number of staff using the service. In effect, you only buy exactly what you need. Scaling up or down is simply a matter of buying more or less seats according to your needs.
3) No special skills required
This is undoubtedly one of DaaS' biggest attractions. With DaaS, you don't need any special skills to administer because your service provider will manage and support the entire virtual desktop environment for you--you are essentially buying an SLA. This makes the solution ideal for SMBs and organizations with inadequate IT resources.
4) Guaranteed performance and security
Reputable DaaS providers employ high-end and highly optimized hardware and software infrastructure that many companies would be hard-pressed to duplicate on their own. This, coupled with the low latency of the cloud, leads to truly impressive performance and minimal downtime.
Being a cloud platform, there are several security layers that are in-built into a DaaS platform including:
- Complete separation of networks--the backbone network, service provider's network and tenant networks are completely separate and non-bridgeable.
- Separation of resources-- virtual desktop storage and tenant hypervisors are maintained separately.
- Secure communication-- DaaS utilizes authenticated connections for communication on different management nodes.
- Secure access-- Horizon Air portal Web applications only use highly secure HTTPS.
- Minimal node functionality-- DaaS features data cenetr security implementations that allow only services enabled on management node templates to run while blocking any unnecessary ports.
5) Highly flexible and easy to implement
DaaS is much easier to pilot and implement and thus provides faster time-to-value compared to on-prem VDI. Additionally, DaaS can flex up and down easily according to your current needs by simply adding or removing desktops as needed. Further, DaaS is deployed via cloud which provides unparalleled availability making it ideal for teams that are located in diverse locations.
Although SMBs still make up about half of DaaS users, larger organizations are increasingly deploying it, a clear indication that the technology is increasingly being viewed as a mature, reliable and high-value service.
