Cloud technologies are systems of servers with programs and databases that can be accessed via the Internet. These servers are located in data centers around the world, allowing companies not to deal with the complex processes of server management and maintenance.
Having created an overview of the basics of the cloud, let's look at the key models for its use: public and private clouds. Although there are other options (hybrid cloud and multicloud), our focus will be on the first two.
Types of cloud solutions
There are three main formats of cloud services, and each of them has its own characteristics:
1. Private cloud: can function both on the provider's site and on the company's equipment. This solution provides full control over resources. Benefits include reliability due to load sharing across environments. However, installation and configuration can take a long time, and the resources consumed should be determined in advance;
2. Public Cloud: Provided for public use by different companies. Performance does not depend on the number of servers created. The benefits are savings in technical support and resource flexibility. However, control and customization are limited;
+ Hybrid cloud: combines elements of the above two models. Despite the flexibility, there are risks associated with data transfer and management complexity.
The choice of a specific solution is determined by the business objectives and the required functionality.
VPC: what is it and why is it needed
VPC (Virtual Private Cloud) is a way to provide cloud computing resources in an isolated network. It streamlines IT processes while keeping critical data secure.
A virtual private cloud allows you to move large amounts of data from physical to virtual space. Thus:
- Information can be stored on a massive scale, applications can be built and run on the web;
- Data remains safe in case of any equipment malfunctions;
- Saves resource and time for maintenance of data centers;
- You can flexibly configure the system, excluding unnecessary functions;
- By using a VPC, you save team time and reduce hardware and maintenance costs.
Private vs Public cloud: what's the difference?
Consider the key differences between these two types of clouds:
1. Ownership and management:
- Private cloud: usually owned and operated by a single organization, hosted on its premises or in dedicated space by a third party;
- Public cloud: owned and operated by a third party and resources are provided to various clients over the internet.
2. Access and multi-user environment:
- Private cloud: usually serves one organization, giving it complete control and privacy;
- Public cloud: resources such as servers and storage are shared among many users.
3. Cost:
- Private cloud: requires initial investment to install and maintain the infrastructure;
- Public cloud: typically operates on a pay-as-you-go basis without the need for a large upfront investment.
4. Customization and flexibility:
- Private cloud: provides deep customization and optimization for specific business needs;
- Public cloud: may limit customization, but provides on-the-fly scalability.
5. Safety and Compliance:
- Private cloud: the organization has full control over security and compliance;
- Public cloud: while public cloud providers typically have strict security standards, customers share this infrastructure, which can present risks.
6. Scalability:
- Private cloud: scalability depends on internal resources and may be limited;
- Public cloud: highly scalable, resources can be quickly added or removed on demand.
How to determine the right IT platform?
If a business is interested in the idea of pay-as-you-go, quick availability of resources, and flexibility, then the public cloud may seem like the perfect solution. However, many are convinced that the private cloud, due to its security, control, data localization and high degree of control, will be optimal for business.
However, it is more important to consider what is right for your business, rather than what is generally considered "best".
Of course, there is no universal guide to action in this matter. However, should a hospital or government entity rely on a public cloud? Of course, no.
The key selection factors are the characteristics of your business and its scale. For example, for a start-up business or a small business with limited funds, a public cloud can be a great solution.
On the other hand, a hybrid cloud that combines elements of both types may be the best solution if you are willing to balance the responsibilities. Increasingly, companies are taking this approach to leverage the best of both worlds.
VPC: for whom the ideal solution
The private cloud is highly flexible, scalable, resource-controlled, provides maximum protection for your sensitive data, and provides ample opportunity for personalization to your company's specific requirements.
Such a cloud is ideal for organizations with complex IT systems. Here are some industries that might benefit particularly:
- Startups and SMBs (small and medium-sized enterprises): allows you to save on maintenance and equipment, guarantees rapid scaling and provides disaster recovery functions;
- Developers of large IT companies: unconditional flexibility, high security and full control over data and infrastructure;
- Fintech and medicine: simplification of the certification process in accordance with legal requirements;
- Telecommunications: the ability to implement professional solutions due to the flexibility of the cloud;
- Industry and logistics: cloud solutions help automate business processes and improve the work of various departments;
- Departments responsible for industry innovation and academic institutions will also find the private cloud ideal for their needs.
In general, cloud solutions for business provide a platform for the implementation of processes, reducing the burden on corporate infrastructure, the use of modern technologies such as Kubernetes, (which is currently under development by OneCloudPlanet) and different programming languages, the private cloud can be appreciated by the main developers, such as DevOps.
Hence
The debate about the superiority of a private or public cloud is inconclusive given the variety of business needs. Each of the models has its own strengths and weaknesses and may be the best solution depending on the specific situation.
The choice between these two options should be based on aspects such as budget, scalability, business requirements, performance, and agility.
