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.

Infrastructure-as-a-Service, commonly referred to as simply “IaaS,” is a form of cloud computing that delivers fundamental compute, network, and storage resources to consumers on-demand, over the internet, and on a pay-as-you-go basis. IaaS enables end users to scale and shrink resources on an as-needed basis, reducing the need for high, up-front capital expenditures or unnecessary “owned” infrastructure, especially in the case of “spiky” workloads. In contrast to PaaS and SaaS (even newer computing models like containers and serverless), IaaS provides the lowest-level control of resources in the cloud.

IBM Cloud Transit Gateway provides a central hub for connectivity, making it easier to provision and manage your networks. With IBM Cloud Transit Gateway, you can create a single transit gateway or multiple transit gateways to connect IBM Cloud VPCs. You can also connect your IBM Cloud classic infrastructure to a transit gateway to provide seamless communication with classic infrastructure resources. Any new resource that you connect to a transit gateway is automatically made available to every other resource connected to it. All data remains within the private IBM Cloud backbone and is optimized for performance. IBM Cloud Transit Gateway supports local and global routing between VPCs and the IBM Cloud classic infrastructure. Connections to and from an IBM Cloud Transit Gateway on the IBM private network are not shown to the public internet. This arrangement reduces public egress and VPN costs and reduces security threats. IBM Cloud Transit Gateway is a fully redundant, fault-tolerant service with no single point of failure within IBM Cloud multizone regions. In-Correct Answer : The following offerings help you interconnect a VPC with an on-premises network VPN can securely connect your virtual private cloud to another private network. You can use VPN to set up an IPsec site-to-site tunnel between your VPC and your on-premises private network or another VPC IBM Cloud Direct Link Connect provides connectivity between your on-premises and IBM Cloud VPC networks through a supported service provider. A service provider connection is useful if your data center is in a physical location that can't reach a dedicated colocation facility, or if your data needs don't warrant a 5 Gbps+ connection. Connect service providers are often used to facilitate multicloud connectivity (public clouds from multiple vendors) through their network. Connect service providers offer layer 2 connectivity, layer 3 connectivity, or both. Work with your service provider to understand their offerings and requirements. IBM Cloud Direct Link Dedicated provides low-latency, high-throughput connections between IBM Cloud VPC networks direct to a service provider-managed WAN, or a client-managed cloud backbone. You can optimize egress traffic from your VPC network and reduce your egress costs. If you can’t connect at an IBM Cloud data center, or don’t need more than 5 Gbps of bandwidth on a Virtual Network Connection, you can use IBM Cloud Direct Link Connect to connect to IBM Cloud through a supported service provider. [Exam tips]: Remember IBM Cloud Transit Gateway used to connect internal VPCs(VPC-to-VPC). IBM Cloud provides connectivity from an external source into a customer's IBM Cloud private network. IBM Cloud Transit Gateway provides connectivity between resources within a customer's IBM Cloud private network.

IBM Watson Studio is a suite of tools and collaborative environment for data scientists, developers, and domain experts.

Microservices are an architectural approach in which a single application is composed of many loosely coupled and independently deployable smaller components, or services. Characteristic of microservices : - Code can be updated more easily - new features or functionality can be added without touching the entire application. - Teams can use different stacks and different programming languages for different components. - Components can be scaled independently of one another, reducing the waste and cost associated with having to scale entire applications because a single feature might be facing too much load.

Broad network access : describes access to services over the network using a Web browser and standard interfaces from any location with a variety of devices including desktop, laptop, and tablet computers.

Explanation

Block storage, is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. Both endurance and performance options provide a range of storage sizes, and the only difference between them is how the Input/Output Operations per Second (IOPS) is delivered for a given storage volume. - Endurance provides pre-set IOPS tiers of 0.25, 2, 4, and 10 IOPS/GB. - Performance allows the user to set a custom level of IOPS beyond 10 IOPS/GB. Under the virtual private cloud (VPC), block storage does not have endurance or performance tiers. Instead, users can set pre-defined or choose custom IOPS when provisioning the storage. Use Cases : Block storage suitable for low latency workloads where consistently high speeds required. Features : - Offer volume size from 20 GB to 12 TB, - Provide encryption for data at rest - Provide IOPS upto 48,000 IOPS - Highly available and resilient.

Multi-cloud generally refers to the consumption of cloud services from two or more cloud providers. Organizations are preferring multi-cloud environment for deploying their application: to avoid vendor lock-in ,to reduce cloud costs and to use cloud provider unique capabilities.

Correct Answers : The Essential Characteristics of Cloud Computing according to NIST : On-demand self-service : A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. Broad network access : Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). Resource pooling: The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, and network bandwidth. Rapid elasticity: Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time. Measured service : Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. Self diagnosis: It's self made option, added for distraction.

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.
