Identity and access management, or IAM is used to control access to resources.

Virtual Private Cloud used to run an isolated environment within a 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. 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. - VPC provides security in two ways. At the instance level protection is provided through security groups. At the subnet level, protection is provided by access control lists. Site-to-site virtual private networks (VPN) can be configured. A public gateway is used to enable egress to the internet for all virtual server instances on the attached subnet. - VPC provides flexibility when customers securely connect to on premises or remote infrastructure. VPCs can be created in various regions around the world. Customers can select a private IP address or bring their own IP address for cloud applications. Using Direct Link helps create a dedicated connection between the cloud and on premises resources. This allows an organization to extend its network and provide a consistent connection without using the public internet. - Responsiveness VPC makes it possible to create responsive cloud applications. Instance profiles with elasticity are used when creating applications for workloads, horizontal scaling, performance monitoring, and load balancing services.

A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing environment on shared public cloud infrastructure. You can subdivide a VPC with subnets, where each subnet can reach the public internet through an optional public gateway. You can assign an FIP to any instance to reach it from the internet, or the other way around. This is independent of whether the subnet is attached to a public gateway. Subnets within IBM Cloud VPC offer private connectivity; they can talk to each other over a private link, through the implicit router. Setting up routes isn't necessary.

Cloud-native applications are designed to run on a cloud-based infrastructure. A cloud-native application takes advantage of cloud computing models to increase speed, flexibility, and quality and to reduce deployment risks. Typically, cloud-native applications are developed as loosely coupled microservices that run in containers that are managed by platforms.
