Cloud computing can seem confusing. But it doesn’t have to be.
Simply put, cloud computing is the storing and accessing of data and programs over the internet as an alternative to the local computer or server’s hard drive.
The term “cloud” originated from technical diagrams in which the Internet was represented as a puffy white cloud that could accept connections and dispense information as it floated in space.
In cloud computing, software and services reside on servers (hardware) that are in large data centres with resources that are shared by many users. Because the resources are shared, users can access high-quality server hardware at a reduced cost. SysGen offers customers Atmosphere, a cloud service specifically tailored for small and medium-sized businesses. This enables organizations to access enterprise-grade hardware at a reasonable cost, ensuring technology runs quickly and data is stored safely.
Understanding the ways to connect to the cloud, and how each will impact your business are important considerations before moving to the cloud. Each business differs in how quickly it needs to access data, privacy requirements, cost, as well as user interface customization. And, each of the three ways outlined serves each of these needs differently.
With Virtual Private Network or VPN, your computer accesses a server through the internet, using an encrypted connection. This secure connection can be thought of as a tunnel between your computer and a server operated by the VPN service in a remote destination.
The benefits of using a VPN include the fact that your internet connection is completely secure because it is encrypted, end to end. No prying eyes can access the network. Additionally, connectivity is possible on most mobile devices, and the ability to control user access to the network is high.
Downsides of a VPN connection are that because of the data encryption and security, data speed is slow. Additionally, increased network complexity means that it is more expensive to fix and update the network and specialized support is required. Finally, manual installation of a VPN client is often required, which is labour intensive.
The second way to connect in cloud computing is through a Remote Desktop Server or RDS. With RDS, only the software user interface is transferred to the user’s computer screen. All data is stored on a remote server, and any user input is transmitted to the remote server. What appears on the computer screen is arriving from the server via the internet. All users have the same desktop experience.
The reasons for connecting to cloud computing via an RDS are that because a single operating system image is administered, low bandwidth is required, and server machines required are low. Additionally, an RDS is simple to deploy and software redundancies don’t occur. Finally, applications, patches and driver updates can be managed from one location, so less work is required.
Disadvantages of using an RDS are that the generic interface doesn’t provide a customized user experience, and as a result, users will see applications that don’t necessarily pertain to them. Additionally, the server operating system is often different to the end user than a consumer operating system. Finally, because all users have access to the RDS server, there’s a risk of server infection or malicious activity.
The final way to connect to cloud computing is through Virtual Desktop Infrastructure or VDI. With VDI, each user is given dedicated space on a remote server and can create a customized desktop experience that can be accessed anywhere via the internet. The key difference between VDI and RDS is the customization of the desktop – instead of a generic interface that everyone accesses once logged in, VDI users have their own user experience.
A benefit of using VDI is that each user has a customized operating experience that is stored on a server. This results in lower user hardware costs because less storage capacity is required on each individual computer. Applications, patches and driver updates can be managed from one location, resulting in less work. It is also simple to update and manage software across all systems. Finally, with VDI, it is easier to deploy machines en masse.
Drawbacks of VDI center around what also makes VDI beneficial. Compute requirements are higher than RDS, and as a result, powerful server hardware is required for optimal performance. This also results in higher storage capacity requirements. And, licensing costs are higher because each user requires their own software on their own computer.
It’s important to understand how your business can connect to cloud computing, and which option is best for you. Especially given that each business is unique in terms of its user and security needs. Some businesses require an encrypted connection, while others only need a generic interface for employees to connect and work from.
