The Cloud Server service allows flexible management of the resources of a remote virtual server (VPS). That is, the concrete advantage of having complete control over the server machines without the disturbance of their physical management. There will be no need to update, manage or restart a physical machine.
The servers created through the Secure Online Desktop (SOD) service are always online, if one server were to have problems, this would be immediately replaced by another to guarantee the continuity of the virtual machine service.
Create the Cloud Server in a few clicks
It is possible to set up a VPS in a few steps by accessing the management panel. From this you can create and delete servers, as well as manage the resources allocated to the single virtual machine.
Payment is limited to the time of use of the service, without any contractual obligation. It is possible to stop the service at any time without any problems or additional costs.
Through the functionalities offered, it is possible to manage the created virtual machines in an extremely flexible way. The cost will always be linked to the actual resources used.
Resources automatically assigned
The Secure Online Desktop Cloud Server service allows you to set autoscaling rules for each virtual machine involved. Through this feature, it is possible to resize RAM memory, CPU and storage resources automatically, respecting customizable rules.
Resources are not wasted by avoiding that you pay for unused computing power or memory. This intelligent use of resources is managed by customizable rules for scalability.
For example: a rule could force the RAM memory to increase by 1024 Mb if the virtual machine uses more than 90% of it for a period longer than 10 minutes. You can also further limit this parameter to a maximum increase of 5 Gb within 24 hours.
Keep in mind that once RAM, CPU and disk have increased through this system, they will not automatically decrease thereafter. If the greatest demand for resources had been only a momentary peak, it will be necessary to set the starting parameters of the VPS again.
In addition, some operating systems offered as templates allow the resizing of RAM and CPU resources without restarting the machine. The reboot is however necessary in the case of resizing the storage disk or if the added RAM memory exceeds 16 Gb.
Virtual Machine backup system
SOD’s Cloud Server service also offers an automatic backup system. No additional backup management software, therefore, that can be set with four restore points: daily, weekly, monthly and yearly.
Note that the data of the machines created remain in your possession and can be downloaded locally at any time.
Operating systems included in the offer
SOD’s Cloud Server plans include operating system templates ready to be installed on the virtual machine. Numerous operating systems are available Windows, Linux and FreeBSD, 32bit as well as 64bit. In a few clicks it is possible to activate a VM, install an operating system and switch it on.
In addition to operating systems, it is also possible to have access to a JumpBox library of Open Source web applications. The offer of software available for VPS is really rich and accessible wherever you are.
No license fees for operating systems available, it’s all included in the cost of the service.
Firewall and security
With the Cloud Server of the Secure Online Desktop, a firewall is available included in the price, customizable with any rule based on the specific needs of the customer and the specific use to be made of the machine.
You won’t have to worry about anything in the security field. SOD will take care of guaranteeing always safe and robust infrastructures.
In terms of reliability, the Server Cloud service has enterprise architectures for managing redundancy. If one server turns out to be unreachable, another will take over immediately, guaranteeing the continuity of the service.
Offer and prices
There are four plans available for the Cloud Server service and can satisfy every VPS need. The costs are monthly without any time constraint, therefore it is possible to completely stop the service from one month to the next.
It is possible to take advantage of all these features through the control panel accessible from every platform: Apple, Windows and mobile. Manage your VPS in complete freedom from any device.
Create and manage your virtual server in minutes with SOD Cloud Server. You can also try the service for free for a day!
vps
A virtual server (Cloud server) or VPS (Virtual Private Server) is a full-fledged server with its own operating system and well-defined hardware features only that unlike a classic server it shares physical resources with other virtual machines in this way multiple VPS can run simultaneously on the same server (hypervisor).
This virtualization technique allows significant cost savings and an optimization of hardware resources as it is possible to run multiple operating systems on the same hardware.
VPS – Advantages / Disadvantages
Advantages:
♦ Migration: It is possible to “move” (migrate) a VPS from one server (hypervisor) to another (even without interruption of service).
Example: You have created a server on a hypervisor in Italy and you want to move it to a server in America. With a VPS, as long as the Cloud Provider has another Datacenter in America, this can be done quickly.
♦ Scalability: It is the possibility of increasing or decreasing the hardware resources (CPU, RAM, Disk, etc) without rebuilding the VPS and in some cases without restarting it in full transparency to users who use the services provided.
Example: A VPS of 2 cores, 1 GB of RAM and 20 GB of disk has been created but after a few months we realize that the RAM memory is insufficient for the services provided and it is necessary to increase it. With a VPS it is very easy to solve this problem, just increase the RAM from the configuration panel and the new configuration will be applied (in the case of linux systems without the need to reboot).
♦ Autoscaling: It is the possibility to increase or decrease the resources (scaling) automatically according to well defined hardware policies. This technique is extremely valid in cases of load peaks.
Example: A VPS has been created with 2 cores, 1 GB of RAM and 20 GB but in some periods of the year due to the high user access these resources are not sufficient, then in this case it is possible to configure these policies:
a) If the CPU is at 90% for more than 1h then the CPU of a core increases every 30min for a maximum of 6 cores and then if the CPU is less than 10% for more than 1h decrease the CPU of a core every 30 min up to a minimum of 2 cores.
b) If the RAM is 99% for more than 1h then increase the RAM of 1Gb every 30min for a maximum of 32Gb and then if the RAM is less than 50% for more than 1h decrease the RAM of a core every 30 min until at a minimum of 1Gb.
♦ Low cost: by comparing the cost of a VPS to that of a fiscal server like hardware resources, the cost of a VPS is much lower, especially considering that some cost items are already included in the VPS fee. :
a) Energy consumption;
b) Internet band;
c) Cost of public IP addresses;
d) Costs related to housing (cooling, surveillance, etc);
e) Firewall;
f) Technical assistance.
Disavantages:
♦ Shared resources: Depending on the configurations and characteristics of the Cloud Provider, some hardware resources, such as the CPU, could be shared so performance may be lower than a physical server. This condition is not always true as it is possible to request a 100% allocation on all hardware resources to your Cloud Provider.
Limits:
♦ OS Virtualization: Not all operating systems and platforms can be virtualized (Eg AS400, Apple OS).
♦ Band: Although this is not an inherent problem of virtualization itself there could be latency differences in the Internet connection between a physical server in the company and a VPS if users are predominantly within the company and if the company has not an adequate Internet line.
Example: A physical server in the customer’s DMZ is accessed by its LAN users via a 10Gb line, if the server is virtualized and becomes a VPS at a Cloud provider, access to it is transmitted via the client’s Internet line which may be more slow.
False myths:
♦ A VPS does not have the same performance as a physical server: By allocating 100% of the physical resources and correctly dimensioning a VPS the latter has nothing to envy to a physical server from a performance point of view.
♦ A VPS is less secure than a physical server: A VPS can have the same degree of security as a physical server because it is possible to adopt the same security measures (Firewall, Antivirus, Hardening, VPN) applicable to a Fiscal server.
