Virtual Private Servers (VPS) hosting is a virtualized solution for hosting, wherein certain key attributes like the memory space and CPU cores are allocated to a single tenant as a dedicated space and are located on a single parent server.
Unlike shared hosting wherein the resources are shared among a distinct set of clients, the resources are managed exclusively by one client as per the service level agreements (SLAs).
Hosting is a simple term wherein a service is granted to a client for a period in agreement to service level terms and conditions.
The hosting in the information systems environment could be a dedicated server, a specific space in a server, or could be the whole data center.
The VPS hosting is technically about data centers using the memory machines interconnected as one major single memory machine.
Such data centers empower the service providers to offer VPS services to the clients.
In general, three types of hosting services in the trend are dedicated servers, shared servers, or VPS.
The flexibility offered by many of the reputed service providers in the VPS servers enables the customers to choose the quantum of storage essential in line with customized solutions or predefined service offerings.
Some of the additional benefits from the service package are dedicated IP, bandwidth, and dedicated storage space managed in a partitioned environment.
Among the critical success factors in reaping potential benefits of using the hosting services is the speed available in the hosting environment.
For large volume transaction systems or high traffic systems, VPS hosting solutions offering super speeds is paramount.
When it comes to speed and service quality offerings, phenomenally the comparisons are amidst NVMe Vs. SATA Vs. SAS.
What is NVMe SSD?
The non-volatile memory express standard is reliant on the NVM Express Base Specification published by NVM Express Inc. which is a nonprofit consortium founded by the tech industry leaders.
In NVMe, the services are offered in compliance with the specifications defined by a consortium, for the functionality of the software communication with non-volatile memory across supported transports.
The latest in the offerings is NVMe 2.0 having some extended specifications to the base specifications of NVMe.
The NVM Express Base Specification iterates the storage protocol and an interface optimization by the host controller, enterprise systems that rely on the SSDs based on PCle.
Technically, PCle is a serial expansion bus standard catering to the systems to attach peripheral devices.
It also offers lower latencies and higher transfer speeds than the older bus technologies.
As PCle in general every bus has its dedicated connection, competition for bandwidth is less, and there is an increased speed for processing.
The flexibility of the lines empowers the system to have better performance with increased lines, despite some cost hikes for more lines.

The Simple Introduction of SSD
It is a non-volatile storage device adapted for persisting electronic data.
Unlike a hard disk drive or other conventional solutions, the SSD does not constitute any moving parts that tend to fail.
SSD relies on silicon microchips for information storage, and thus it requires less power and generates less heat than other conventional storage drives.
In the contemporary range of SSD solutions, they are enabled with flash memory technology, and every device comprises flash controllers, and one or more flash memory chips.
Speeds and Performance
NVMe plays a vital role for SSDs in improving the throughput and IOPS, thus leading to latency reduction and an increase in speeds.
NVMe-based drives can deliver throughputs up to 32 Gbps.
The efficacy with which the speeds are managed also helps in a drop in the latency rates to a significant extent.
Based on the workload type, there can be a potential difference in the maximum NVMe speeds.
However, one fundamental assurance in the technology is its outperformance in comparison to SAS and SATA across all the parameters.
NVMe relies on the streamlined command set for processing any kind of I/o requests, which in general is lesser than half the number of instructions triggered in SATA or SAS systems.
SATA and SAS can support only the I/O queue at an instance.
The SATA queue has the capability of 32 outstanding commands, and SAS has the scope of 256 commands in line.
In contra to the limitations in SATA and SAS, NVMe can hold around 65000 commands per queue and can deliver considerable process outcomes.
Thus, in a comparative analysis among the SAT, SAS, and NVMe, the parallel processing capabilities of SSD is superior to NVMe.
The other key advantage of the NVMe is the capacity of remote direct memory access adding up the reduction in latencies in the software stack.
In sideline of technicalities, in simple terms, the scope and efficacy with which the NVMe can deliver faster processing services in VPS server hosting environment is a key value proposition in offering for the clients.
From a faster speed perspective, SATA and SAS protocols are categorically developed for HDD devices.
SATA protocol despite being known for its speed and reliability, both the protocols can handle HDD workloads.
Any instances of storage-related roadblocks are the resulting outcome of the issues in the drive.
Whereas in SSDs such complexities were negated, and there is the full advantage of the driver’s performance capabilities improving significantly.
Functional limitations imminent in the SATA and SAS were effectively addressed in the NVMe.
Over time, new age SATA and SAS were seen to have reduced latencies but there is hardly any match to the outcome generated from NVMe.
In a question on what the clients should choose for faster processing, most of the data centers favor NVMe for its supreme performance.
