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

Block and file storage are common in traditional data centers but can often struggle with scale, performance and distributed characteristics of cloud. Thus, of the three, object storage has thus become the most common mode of storage in the cloud given that it is highly distributed (and thus resilient), it leverages commodity hardware, data can be accessed easily over HTTP, and scale is not only essentially limitless but performance scales linearly as the cluster grows.

Explanation

Private cloud (also known as an internal cloud or corporate cloud) is a cloud computing environment in which all hardware and software resources are dedicated exclusively to, and accessible only by, a single customer. Private cloud combines many of the benefits of cloud computing—including elasticity, scalability, and ease of service delivery—with the access control, security, and resource customization of on-premises infrastructure. Advantages of private cloud include the following: Full control over hardware and software choices. Private cloud customers are free to purchase the hardware and software they prefer, vs. the hardware and software the cloud provider offers. Freedom to customize hardware and software in any way. Private cloud customers can customize servers in any way they want and can customize software as needed with add-ons or through custom development. Greater visibility into security and access control, because all workloads run behind the customers’ own firewall. Fully enforced compliance with regulatory standards. Private cloud customers aren’t forced to rely on the industry and regulatory compliance offered by the cloud service provider.

DevOps is an increasingly common approach to agile software development that developers and operations teams use to build, test, deploy and monitor applications with speed, quality and control. DevOps is relevant to any kind of software project regardless of architecture, platform or purpose. DevOps enables fast and automated deployment of services. DevOps brings together development and operations teams to overcome configuration and deployment delays. With a DevOps strategy you can do the following: - Accelerate the delivery of reliable software. - Balance speed, cost, quality, and risk with increased capacity to innovate. - Reduce time to customer feedback with improved customer experience.

Explanation

Block storage, sometimes referred to as block-level storage, is a technology that is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. Developers favor block storage for computing situations where they require fast, efficient, and reliable data transportation.

Explanation

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.
