What is a private cloud? Definition & use-cases

The private cloud is a type of infrastructure used by one company without sharing the physical and the virtual resources. This kind of infrastructure can be deployed on the company’s own hardware or on rented computing resources. The cloud infrastructure is hosted by the provider in a data center or by the company itself. The client gets access to the cloud through the internet.

The advantages of the private cloud

Private cloud hosting has a number of advantages compare to bare-metal servers or the public cloud.

1. Reliability

The main advantage is high security for the data stored on the isolated platform. Access to the company’s IT infrastructure is regulated by user access rights.

If a business mainly deals with data and applications, it must have high demands towards data security. Employees get different access rights to the confidential data based on the company’s org chart.

This is also important for enterprises who have been prioritizing confidentiality long before the era of digitalization. The military & government sectors are good examples of enterprises that regularly employ private cloud security.

2. High speed

The data transfer speed in the private cloud is higher due to the fact that the resources are not distributed between users. This way, a company can upgrade the infrastructure’s performance.

3. System isolation

The main principle of the private cloud is the exclusive use of resources dedicated to the company that owns the cloud. The biggest advantage of isolated resources is that they’re only available to the personal cloud’s owner and do not need to be shared. This is especially important for businesses that constantly need computing resources to work with large volumes of data.

4. Quick system configuration

This type of cloud infrastructure can be reconfigured at any given moment based on the company’s current needs. This improves the speed at which the IT department can deal with tasks. The service required by the business can be deployed in about 10 minutes; it’s enough to set tasks for the virtual machines. When maintaining your own data center, such operations can take 5 to 8 weeks, starting with the process of ordering equipment and installing software.

The private cloud is a good solution for a business that requires an infrastructure that is safe, scalable and relatively inexpensive compared to maintaining an on-premises data center.

Creating a private cloud

Building a private cloud is a multi-stage task which requires informed decision-making and the participation of qualified specialists.

When choosing a solution, one must consider a number of factors. These factors include regulatory, political and economic risks. The software that a company uses renders the business dependent on the vendor and his policies. The private cloud’s roadmap is the next stage of the process. When developing the cloud, it is vital to foresee the upcoming tasks, the increase in workloads and the appearance of new technologies. Then, the business has to make a choice between a standard solution with pre-existing functionality and customization for specific needs. Standard solutions are a good way to implement the infrastructure in a short timeframe. Creating a personalized solution is a complex task that will allow the company to use tailor-made tools.

When the choice is made and the vendor’s contract is signed, the stage of the pilot installation begins. This way, the client can evaluate all functions and possibilities. Deploying a pilot version of a cloud can take 1- 2 months for a standard solution. After the testing, the platform is ready for use. The private cloud provider is responsible for all support: technical maintenance, user training, consultations on the platform’s utilization and instructions on how to solve the most common issues.

If you are planning to deploy your corporate systems in a private cloud, entrust a team of experts with this task. Cloud migration is a complicated and time-consuming process. Experienced specialists can carry out the migration within your preferred timeframe and take business needs into account while guaranteeing the quality of the end result.

Note: SLA - Service Level Agreement is a formal agreement between the vendor and the client, which contains the description of the service, the rights and responsibilities of the parties, as well as a guaranteed level of quality.

Private cloud examples & use-cases

Ensuring the security of all data and solving corporate tasks put before the employees are the main goals of creating a private cloud. Not that the cloud can be used to improve the mechanism of forming the budget necessary to support and scale the resources. The need for resources can be evaluated beforehand by deploying the infrastructure in test mode and reconfiguring it by adding resources or turning them off, thus planning expenses.

Private cloud solution 1. Client data protection

An interesting example of how SIM-Networks created a private cloud for a large company in the gaming industry.

The client wanted to increase the level of data security and to improve the performance of his IT infrastructure. The main requirement towards the project was to guarantee security for the company and the client’s player base. Considering the intense peak workloads and the specifics of the industry, we offered to build a fault-tolerant private cloud based on a cluster of dedicated servers with a separate data storage system. This way, the client got an individual project developed with business specifics and unique requests in mind. The high-performance fault-tolerant cluster of cloud servers guaranteed confidentiality for the company, as well as stable access to the client’s services. The uptime of the infrastructure is not affected by peak workloads.

Private cloud solution 2. Resource efficiency evaluation

The client wanted to evaluate the amount of resources necessary for his business to function efficiently before migrating to the private cloud. We solved this task by deploying the client’s IT infrastructure in the public SIM-Cloud beforehand so that the client could precisely evaluate his resource needs, as well as avoid unnecessary expenses when ordering equipment and software for the private cloud. The client used this data to plan resource scaling as the business grows. The migration was carried out with minimal downtime for the client’s services.
