Virtual private cloud, also known as VPC, is one of the popular cloud solution options that enterprises would consider because of its scalability and high availability. As a secured cloud solution that is privately hosted within a public cloud, it offers businesses competitive advantages and the agility to execute more flexible approaches with the power of cloud computing. In the public cloud, there are unique resources reserved just for a specified client that others could not access, and this is what a virtual private cloud means. A virtual private cloud could be isolated from other resources within a public cloud by several technologies, including subnets, VLAN, and VPN. Usually, a virtual private cloud consists of a CPU, virtual memory, storage, an accessible network, and a physical port.
Businesses use a virtual private cloud for three main reasons. Firstly, it supports businesses to scale up or down freely. It is because the virtual private cloud is hosted by public cloud vendors. When a business wishes to expand and add more resources to the virtual private cloud, all they have to do is to make a request to the cloud provider. Second, it is easy to change their cloud strategies using VPN technology as well. A virtual private cloud could be easily connected to a hybrid cloud, another public cloud, or other on-premises infrastructures. Third, it boosts the performance of the businesses quickly and helps them to acquire higher efficiency in operation. Compared with those on-premises solutions, a virtual private cloud could help companies to take advantage of cloud computing with data security.
Many might mistake virtual private clouds for private clouds. However, the fact is, virtual private clouds and private clouds are different. The virtual private cloud is about reserving resources within the shared environment, which is the public cloud. A private cloud, on the other hand, is a cloud service specifically offered to the specified client only. The entire cloud service is contributed by the private cloud service owner. Below has listed out the key differences between the two cloud infrastructures:
Virtual private cloud allows organizations to control the scale of the network and resources very easily as most resources are operated by the public cloud vendor. Virtual private cloud users are getting access to the resources, instead of developing the resources on their own. In contrast, the private cloud is fully owned by the organization, which means that it might take the company more time to customize the solutions for its own use. The difference between the two makes virtual private cloud more agile for companies.
In most cases, virtual private cloud infrastructure costs less than private clouds. The private cloud might also involve hardware setup, IT talents’ efforts for research and development, and regular maintenance costs after installation. A virtual private cloud would cost less in comparison, as public clouds are more flexible in general. There are neither hardware requirements nor post-install costs incurred.
NEW TECHNOLOGIES ARE CREATING NEW POSSIBILITIES. Time-to-market and high strategic agility are key success factors in today's fast-paced business environment. With rapid development in the IT sector over the last few years, cloud computing is no longer IT vaporware but a reality. Cloud computing is highly relevant when considering new business opportunities and technology possibilities - it is a way to increase capacity, or add capabilities on the fly, without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real-time over the Internet, extends existing IT capabilities.
