The minutes of a Private cloud compared to a VPS

Cloud servers have gained massive popularity in a relatively short time. From medium enterprises to a tech-giant, there is hardly a place where cloud servers are not deployed. Cloud has brought Virtualization to reality from the realms of vision.

The popularity for computing has now encompassed individuals and is no more confined to just enterprises. Among individuals, cloud goes by the concept of File hosting service. File hosting allows users to upload personal documents, backups, and database to an online storage.

The intense customizability of cloud servers is the key motive behind businesses gluing to it for their IT needs. Cloud servers allow individuals to handpick things that fit their business.

The choice of Private Cloud servers (PCS) over a Virtual Private Server (VPS) is a concern that many businesses topple upon. A PCS resembles a VPS in many aspects, but differs in only a few.

Many of us are left bewildered with the choice of a private cloud over a virtual private server. With this article, we have aimed at facilitating a crystal clear understanding of private clouds, and how minutely it differs from a VPS.

Private Cloud- What it is?

A cloud computing service, dedicated to the use of a single organization, in which the hardware is provisioned over a private infrastructure is called a private cloud.

VPS- What is it?

A VPS mimics the environment of a dedicated server on a shared platform. It achieves this by sharing resources of a shared server among multiple tenants. Each tenant is allocated a fixed share of technically separated resource from the server.

How VPS and Private Cloud Resemble each other?

• Both VPS and PCS benefit from isolated resources reserved especially for their needs. Server resources in a VPS is only virtually isolated from other tenants, whereas in a Private cloud server, the resources are both physically and technically separated.
• A VPS serves the interest of a single organization or user, much like PCS does.
• Network traffic from neighbouring servers seldom affects the performance of another VPS hosted on the same physical server. Same goes with private cloud servers.
• Both VPS and PCS can be provider-managed services, permitting administrators to continue using application resources without worrying about managing the underlying hardware.

How PCS differs from VPS?

Isolation

VPSes share resources from the same dedicated server. A virtual environment separates resource of one VPS from that of its neighbouring servers. Different providers have different ways of allocating resources to the tenants.

A Private Cloud server is procured on a private infrastructure, and are physically separated from other servers. Unlike VPS, the alienation of resources for a particular PCS does not require deployment of any virtual environment.

Security

The idea behind procuring cloud within organization’s own-premise is to achieve state-of the art data-security. Since such servers have no physical or technical connection with any other server, a private cloud is inarguably more secured than a VPS.

The above statement does not imply that VPSes are any less secure. Providers employ enough filters and techniques to safeguard data stored on a virtual private server.

Management and customizability

Both VPSes and Private clouds lay complete control and management at the hands of their network administrators. However, with VPS, some control still lies with the provider; the provider maintains the computing infra as per his own policy.

A self-owned Private Cloud server is entirely at the administrator’s disposal to manage and to customize. Admins not only control the server, but also the principal server-hardware and infrastructure.

Scalability & flexibility

Scaling VPS is almost always followed by a server setup which can be an exhausting task to carry out. When it comes to scalability, the cloud servers have a slightly upper edge for the reason that cloud hosting providers handle the entire server setup at their own end.

Virtualization

Virtualization means creating a pool of server space by consolidating hardware infrastructure irrespective of where resources lie physically.

With VPS, one cannot achieve virtualization as each virtual private server points to a unique physical disk address.

A private cloud pools resources from multiple servers to act like a single virtual storage. The virtual space thus created does not correspond to any server in particular, but to the combined pool of servers.

Cost

A VPS is hosted on the provider’s infra, that too on a shared server. Private cloud servers require setting up of an entire infrastructure for computation. Though, a private cloud can also be procured over a rented space, it would still cost way more than a VPS.

Performance

A VPS hosting only offers the assured level of performance, as it shares only a fixed part of resources from a central dedicated server. Static allocation of resources prove to be problematic during high loads. During peak loads, VPSes get clumsy as the allocated resources aren’t adequate enough to cater the increased resource requirements.

With Private cloud servers, the entire resource is accommodate any over-the-top network traffic. Moreover, if the load still gets past the server’s capabilities, the cloud can momentarily be scaled, and shrunk once the load gets back within the server’s limit.

Reliability

VPS, like any other physical server, has a single point of failure. So, if the host server malfunctions, all the VPSes capsuled on that server are bound to fail.

Private clouds deploy virtual storage. Even if one of the servers in a pool fails, data from the remaining server-pool is still accessible. This ensures a high uptime availability.

Indubiously, Private cloud servers are more reliable than virtual private servers.

Thought to retain

IT has developed a craze for the flexibility that has accompanied cloud computing. Cloud is seen as an economically viable alternative to almost all storages. Entrepreneurs have motioned the migration of their business from cheap windows VPS. Professionals have already started exploring and modifying cloud to their interests.

Organizations already having a well-established dedicated server’s network have also embraced cloud computing. Enterprises that demanded unmatched security from conventional server setups are procuring their own private cloud servers.

It would be interesting to see for how long will the craze for cloud computing thrive.
