IBM C1000-142 - IBM Cloud Advocate v2

The term ‘cloud computing’ also refers to the technology that makes cloud work. This includes some form of virtualized IT infrastructure—servers, operating system software, networking, and other infrastructure that’s abstracted, using special software, so that it can be pooled and divided irrespective of physical hardware boundaries. For example, a single hardware server can be divided into multiple virtual servers. Virtualization enables cloud providers to make maximum use of their data center resources. Not surprisingly, many corporations have adopted the cloud delivery model for their on-premises infrastructure so they can realize maximum utilization and cost savings vs. traditional IT infrastructure and offer the same self-service and agility to their end-users. Cloud computing benefits Flexibility: Users can scale services to fit their needs, customize applications and access cloud services from anywhere with an internet connection. Efficiency: Enterprise users can get applications to market quickly, without worrying about underlying infrastructure costs or maintenance. Strategic value: Cloud services give enterprises a competitive advantage by providing the most innovative technology available.

Three transformational paths for application modernization are infrastructure, architectural and delivery.

IBM Cloud Transit Gateway helps you connect and manage your IBM Cloud Virtual Private Cloud (VPC) networks. Note : A virtual private cloud (VPC) is a private cloud within a public cloud.

Kubernetes relies on YAML configuration files to maintain the application state.

Serverless computing is a cloud computing execution model that provisions computing resources on demand and offloads all responsibility for common infrastructure management tasks. They are auto scalable so it can handle extremely active traffic periods.

Serverless computing does-not means there are no physical servers utilized, of course there are servers, but we don't have to manage them, in background cloud provider manage (provisioning, scheduling, scaling, patching and more) for us, this gives developers more time to develop and optimize their front-end application code and business logic. And with serverless, customers never pay for idle capacity. They pay only for the resources required to run their applications, and only when those applications are running.

Serverless is a polyglot environment, enabling developers to code in any language or framework - Java, Python, node.js - with which they're comfortable. Because serverless scales up and down on demand in response to workload, it offers significant cost savings for spiky workloads. But it does not offer the same savings for workloads characterized by predictable, steady or long-running processes; in these cases, a traditional server environment might be simpler and more cost-effective.

Serverless Implementations differ across service providers, and capabilities vary, including supported runtimes, authentication, scaling and monitoring.

Serverless architectures are well-suited for event-driven, IOT and stream-processing workloads most notably open-source Apache Kafka event streaming platform.

Benefits:

- Pay only for the time for our code will run.

- Developer don't have to take care of servers or infrastructure, it maintains by cloud provider, so

they can focus more on development and business logic.

- API Management & Integrated event sources.

- Serverless scales up and down on demand in response to workload

Explanation

The DevOps toolchain tools build, deploy, and manage apps that make development and operations repeatable and easier to manage. A continuous delivery service is required before an IBM Cloud Toolchain can be executed. Toolchains are a set of tools that are used to automate the process of building, deploying, and manage applications. You can create toolchains from a variety of sources including other IBM Cloud services, third-party software, and open-source tools.

Explanation

Hypervisor : a hypervisor is a lightweight software layer. A hypervisor is an abstraction layer that abstracts physical compute resources, making them available virtually to virtual machines (VMs). The hypervisor assigns processors, memory, and storage to each VM. It keeps VMs separate so that they do not interfere with each other. Features of a hypervisor are: 1. A hypervisor is software that runs on the physical server or host. 2. It pools the resources from the physical server and allocates them to a virtual environment. 3. Hypervisors are leveraged to virtualize hardware whether it's on-premises or in the public cloud.
