Key Takeaways

A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing environment on shared public cloud infrastructure. A VPC gives an enterprise the ability to define and control a virtual network that is logically isolated from all other public cloud tenants, creating a private, secure place on the public cloud.

Agility: Control the size of your virtual network and deploy cloud resources whenever your business needs them. You can scale these resources dynamically and in real-time.
Availability: Redundant resources and highly fault-tolerant availability zone architectures mean your applications and workloads are highly available.
Security: Because the VPC is a logically isolated network, your data and applications won’t share space or mix with those of the cloud provider’s other customers. You have full control over how resources and workloads are accessed, and by whom.
Affordability: VPC customers can take advantage of the public cloud’s cost-effectiveness, such as saving on hardware costs, labor times, and other resources.

Flexible business growth: Because cloud infrastructure resources—including virtual servers, storage, and networking—can be deployed dynamically, VPC customers can easily adapt to changes in business needs.
Satisfied customers: In today’s “always-on” digital business environments, customers expect uptime ratios of nearly 100%. The high availability of VPC environments enables reliable online experiences that build customer loyalty and increase trust in your brand.
Reduced risk across the entire data lifecycle: VPCs enjoy high levels of security at the instance or subnet level, or both. This gives you peace of mind and further increases the trust of your customers.
More resources to channel toward business innovation: With reduced costs and fewer demands on your internal IT team, you can focus your efforts on achieving key business goals and exercising core competencies.

Compute: Virtual server instances (VSIs, also known as virtual servers) are presented to the user as virtual CPUs (vCPUs) with a predetermined amount of computing power, memory, etc.
Storage: VPC customers are typically allocated a certain block storage quota per account, with the ability to purchase more. It is akin to purchasing additional hard drive space. Recommendations for storage are based on the nature of your workload.
Networking: You can deploy virtual versions of various networking functions into your virtual private cloud account to enable or restrict access to its resources. These include public gateways, which are deployed so that all or some areas of your VPC environment can be made available on the public-facing Internet; load balancers, which distribute traffic across multiple VSIs to optimize availability and performance; and routers, which direct traffic and enable communication between network segments. Direct or dedicated links enable rapid and secure communications between your on-premises enterprise IT environment or your private cloud and your VPC resources on public cloud.
