What is Private cloud
Today’s cloud computing is divided in three categories:
- Public Cloud
- Private Cloud and
- Hybrid Cloud computing (a combination of the upper two)
The advantages that the private cloud brings to a company, compared to the public cloud are similar, in sense of the
- Scalability and
- Self Service,
but the architecture they are brought through is owned or leased by the company.
The difference between the public and the private cloud is that the last is dedicated to a company or organization, whereas the public cloud may serve as many organizations as connected to it.
The Private cloud environment is well-defined and more secure which only the assigned user (organization) can utilize. That provides the user with better control over their data and greater privacy, since it is accessible only by that organization.
Examples for public clouds are:
- Amazon Web Services,
and they share their infrastructure among many users and/or organizations. Therefore, these systems are not be preferred by organizations that request enhanced security, up-time stability or resources management.
Benefits of Private Cloud
Just as the public cloud, the private cloud covers these benefits:
- Self-Service and Scalability;
- Resources Changes On-Demand
- Manipulating with Multiple Machines for complex computing jobs, like Big Data.
Besides this, the private cloud provides hosted services to a limited number of people behind a firewall. It’s a way to to reduce the security issues an organization may have putting its data on public cloud. The public cloud also makes the organizations have direct control over their data.
But private clouds have some disadvantages…
In order to manage the private cloud an in-house IT department should be in charge, rather than a third-party cloud provider. That may bring some additional costs for:
- cloud software and
- cloud management tools,
just as if you owned your private data center.
In order, to lower some of these costs, cloud providers, such as VapourApps, can help to deploy private cloud infrastructures.
Added value to the LANs: Virtualization
What was in the past much used in every enterprise as individual local access network (LAN), now is changing for the private cloud model. It is very close to the traditional LAN model, but there is another added value and its advantages: the virtualization
Therefore, the features and benefits of private clouds are:
- Higher security and privacy; An organization can get a certain level of security from public clouds services. But, using techniques such as distinct pools of resources with access restricted to connections made from behind one organisation’s firewall, dedicated leased lines and/or on-site internal hosting, which are available when implementing private cloud – can keep corporate data and operations security level much higher.
- More control; Since the private cloud is only available to only one organization, that organization will be in charge of its management and configuration, making it inline with their needs to get a custom-tailored network solution. This may a bit increase the costs, which the public clouds reduce with scale generated, by the centralized management of the software
- Cost and energy efficiency; When a private cloud model is implemented in an organization, the allocation of resources can be improved, thus every requirement a department may have can be flexibly be served based on the available resources. So, they make more efficient use of the resources and they minimize the investment into unused capacity over the traditional LANs.
VapourApps Private Cloud Solution
VapourApps is an integrated solution comprised of:
- Virtualization engine – OpenStack on KVM
- Predefined virtual servers based on Debian
- Orchestration and management web dashboard, a customized Horizon dashboard.
VapourApps is a private cloud platform that brings application support using popular technologies as OpenStack and Docker. It consists of an:
- installer (that sets up the OpenStack base on multiple nodes),
- App Suite(pre-existing common apps for businesses and developers),
- Monitoring & Backup (for health checks, performance stats, backing up all apps and data) and
- API (for integrating new apps). It is targeted at developers, small, medium and big sized companies.
The owner of the tenant or the IT administrator, can manage their virtual servers, users, groups and monitor the status of the used application from a single dashboard.
