Configuring And Deploying A Private Cloud – A private cloud is defined as an on-demand cloud deployment model where cloud computing services and infrastructure are privately hosted on a company’s own intranet or data center using proprietary resources. This article explains the basics of private cloud storage and lists some best practices for private cloud implementation in 2021.
A private cloud is an on-demand cloud deployment model in which cloud computing services and infrastructure are privately hosted on a company’s own intranet or data center using proprietary resources.
Configuring And Deploying A Private Cloud
Today, businesses are turning to the cloud for their most important business applications. It is the fastest and cheapest way to deliver IT services. When looking for a secure cloud option, organizations often choose the private cloud. Although businesses were previously reluctant to migrate to the private cloud, it quickly emerged as the most secure cloud model.
Environment Planning For Private Cloud Clusters
Of the three types of cloud computing, private cloud is the best choice for organizations because of the added security it offers. In a private cloud, cloud computing services and infrastructure are privately hosted in a company’s own data center. These services are accessible to an organization’s personnel. This type of cloud is managed by internal resources and is not accessible to people outside the organization. Private cloud is also called enterprise cloud.
Depending on who manages the private cloud environment and where the cloud solution is hosted, a private cloud can be classified into four major types – virtual private cloud, managed private cloud, hosted private cloud, and On-premise private cloud. Let’s look at each one in detail.
A virtual private cloud (VPC) is a type of cloud model that offers the benefits of a private cloud (more control and an isolated environment) with the help of public cloud resources. Although private cloud and virtual private cloud are often used interchangeably, there are many points of difference between the two.

In a traditional private cloud, the company’s internal IT department acts as the service provider, and individual business units act as tenants. In the virtual private cloud model, public cloud providers act as service providers, and cloud users act as tenants. Simply put, a virtual private cloud is a hybrid model of cloud computing in which a private cloud solution is provided on the infrastructure of a public cloud provider.
A regular private cloud is a type of private cloud model where the infrastructure is not shared. It is also referred to as a dedicated or single-tenant cloud. Such a private cloud is managed by a third-party vendor. The vendor provides private cloud support, maintenance, upgrades and even remote management. In some cases, vendors also manage software applications in the cloud.
Hosted private cloud vendors offer cloud servers in their own data centers and are also responsible for security management. In the hosted private cloud model, users get access to additional resources, a support team, high-demand scaling options, as well as a user-friendly dashboard to help with server management.

Unlike hosted private clouds, on-premise cloud solutions allow users to host cloud environments internally. For such a cloud model, it is necessary to have an internal data center to host the cloud server. This type of private cloud model is more secure because they are internally hosted and managed by an organization’s internal IT department. The organization therefore has complete control over the security, configuration and deployment of these servers.
Hewlett Packard Enterprise (HPE) has been the leader in the personal cloud computing market for many years. A private cloud service provider offers customizable private cloud software and infrastructure. HPE Private Cloud can be used with a public cloud to provide faster connectivity with the same security protections as a private cloud. HPE Private Cloud offerings include services, hardware and software. Its private cloud solutions include, among others, Hellion Cloud System Hardware, Hellion Cloud Suite Software, Hellion Managed Private Cloud, and Managed Virtual Private Cloud Services.
VMware offers two types of private cloud solutions. While one solution is completely private, the other is a hybrid solution that offers an integrated stack as well as automated lifecycle management. Although VMware is best known for its virtualization software that runs many private cloud environments, it also offers a number of other services. The VMWare vRealize Suite cloud management platform offers private as well as hybrid cloud management. VMWare Cloud Foundation, on the other hand, is a data center platform for private clouds.

Dell EMC offers two private cloud products. While one is for Microsoft Azure Stack, the other is a turnkey developer platform. Dell, which has always been the leader in the private cloud market, became an even stronger player after the merger with EMC. The company’s cloud offerings include cloud management and cloud security software, virtual private cloud services, and various cloud consulting services.
Oracle’s Private Cloud Appliance is a scalable data center capable of processing mixed workloads. The company’s private cloud solutions include its cloud platform, infrastructure, applications, lifecycle management tools, as well as integration services, with managed cloud services.
IBM’s private cloud design is based on open source frameworks, including Kubernetes and CloudFoundry. The company’s private cloud solutions include IBM Systems and IBM Storage, IBM Cloud Managed Services, Cloud Manager, and Cloud Orchestrator. In addition to the private cloud vendors mentioned above, Microsoft, Cisco, NetApp, Red Hat, and AWS are also major players in the private cloud race.

Although a private cloud is quite expensive, it comes with its own benefits. Let’s look at the various benefits that a private cloud offers:
A private cloud is very secure, no doubt. However, managing the cloud internally can prove to be quite challenging. Here are some other challenges organizations face with private clouds:
Speaking further on the challenges of private cloud, Brian Kelly, CEO, Cloud Bolt, says, “When businesses invest in private cloud technologies, they are responsible for the infrastructure that runs the virtual environment. Size and configuration that can effectively handle the anticipated workload. The challenge is to configure the environment without over- or under-provisioning the required capacity, which can be difficult to track and predict. At the same time, you are responsible for the important corporate responsibility of securing this network environment, mitigating vulnerability attacks and implementing smart, reasonable end-user behavior. It’s a lot, but when executed thoughtfully Hey, that’s a beautiful thing.
Private Cloud Providers Are Being Taken Over By Msps: Learn Why
Investing in a private cloud requires monitoring infrastructure through monitoring, analytics and troubleshooting so enterprises can catch issues before they lead to security breaches or costly downtime due to redundant capacity. Visibility and control of the virtual environment that drives and affects infrastructure capacity also helps identify where problems are occurring.
Private cloud occupies a large share of the global cloud market. According to the fourth annual cloud usage survey by Denodo, a data virtualization company, nearly a quarter of all workloads among 150 global businesses are hosted in the private cloud. As enterprises look beyond one-size-fits-all public cloud solutions toward something more convenient and secure, implementing a private cloud is essential to your IT strategy.
A key drawback hindering widespread private cloud adoption is the lack of scalability. As a private cloud relies on a pre-defined set of resources owned by the enterprise or its cloud partner, it is difficult to scale in traditional ways. Partnering with a hyperscale company like IBM or Equinix can solve this problem.

Hyperscale essentially means that the cloud infrastructure is built to expand based on new demand. Hyperscale compatible private clouds effectively combine the benefits of public and private cloud environments.
Private cloud environments typically require more IT effort and more frequent intervention than public clouds, which are set-and-forget in nature. An enterprise will need a large in-house IT team, advanced tools, continuous training, and significant effort to run an end-to-end private cloud with external support.
This is why it is recommended to partner with a private cloud company that also offers managed services and remotely monitors implementation, use and maintenance. A new solution has also emerged called managed private cloud as a service (currently offered through the Cisco-IBM partnership), where an external partner manages your private servers (in this case, VMware and IBM) in a subscription model.

Even with managed services, enterprises need a robust front-end interface that can help monitor ongoing private cloud activities. What is the storage condition? How are virtual machines and network resources provisioned? Can an automated workflow be defined to resolve the issue?
The front-end user interface (UI) enables all this and more. This reduces the manual effort of the internal IT team and helps enterprises stay on the same page with their managed service provider. Your private cloud partner should also be able to offer a custom automation framework tailored to your business needs.
While private clouds are technically designed as separate infrastructure components with minimal interactions with external resources, this can get in the way of performance and productivity. Therefore some level of intervention is necessary, even if it is an environment somewhat similar to a hybrid
