Security group: With a security group, you can create groups of resources (which may be situated in more than one subnet) and assign uniform access rules to them.A subnet is a portion or subdivision of your VPC the ACL defines the set of IP addresses or applications granted access to it. Access control lists (ACLs): An ACL is a list of rules that limit who can access a particular subnet within your VPC.Two types of network access controls comprise the layers of VPC security: These security features enable customers to define virtual networks in logically isolated parts of the public cloud and control which IP addresses have access to which resources. VPCs achieve high levels of security by creating virtualized replicas of the security features used to control access to resources housed in traditional data centers. 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. 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. Networking: You can deploy virtual versions of various networking functions into your virtual private cloud account to enable or restrict access to its resources.Recommendations for storage are based on the nature of your workload. It is akin to purchasing additional hard drive space. Storage: VPC customers are typically allocated a certain block storage quota per account, with the ability to purchase more.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.These cloud resources-also known as logical instances-fall into three categories. In a VPC, you can deploy cloud resources into your own isolated virtual network. 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.This gives you peace of mind and further increases the trust of your customers. Reduced risk across the entire data lifecycle: VPCs enjoy high levels of security at the instance or subnet level, or both.The high availability of VPC environments enables reliable online experiences that build customer loyalty and increase trust in your brand.
Satisfied customers: In today’s “always-on” digital business environments, customers expect uptime ratios of nearly 100%.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.It is analogous to the “friends-only” or “public/private” controls on social media accounts used to restrict who can or can’t see your otherwise public posts.ĭiscover how IBM can help you on your VPC journey.Įach VPC’s main features readily translate into a benefit to help your business achieve agility, increased innovation, and faster growth. In contrast, having a VPC is like having your own private condominium-no one else has the key, and no one can enter the space without your permission.Ī VPC’s logical isolation is implemented using virtual network functions and security features that give an enterprise customer granular control over which IP addresses or applications can access particular resources. Being a public cloud tenant is akin to sharing an apartment with a few roommates. Imagine that a cloud provider’s infrastructure is a residential apartment building with multiple families living inside. 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. A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing environment on shared public cloud infrastructure.
