Module 1 Flashcards
Bare metal server
also called a dedicated server by some, is a form of cloud services in which the user rents a physical machine from a provider that is not shared with any other tenants. Highlights included advantages and use cases.
Virtual Servers
A virtual server is aserver that shares hardware and software resources with other operating systems (OS), versus dedicated servers.
Autoscaling
provides the customer with the ability to automate the manual scaling process.sets up new instances automatically as more resources are needed and then those instances are shut down and removed when the extra load subsides.
Two type of autoscaling
- Schedule based scaling − like over weekends or holidays. Schedule-based scaling can be used when a company is expecting traffic to spike.
- Resource based scaling − can be used to set up policies for irregular spikes, Irregular spikes can occur when users have a push to get a product to market or an e-commerce site is having a sale and resources are needed to sustain response times
Virtual private cloud (VPC)
A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing environment on sharedpublic 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.
IBM Code Engine
is a fully managed, serverless platform that runs containerized workloads, including web apps, micro-services, event-driven functions, or batch jobs
Code Engine experience is designed so that users can focus on writing code and not on the infrastructure that is needed to host it.
VMware
VMware provides an industry-leading virtualization platform that abstracts processor, memory, storage, and networking resources to create multiple Virtual Servers on a single physical server. Multiple physical servers can be clustered together to create a private cloud.
Citrix
It’s an automated solution built on IBM Cloud bare metal server infrastructure that lets users easily enhance their current on-premises virtual desktop infrastructure (VDI) implementation by extending or migrating their deployment to the public cloud.
Dizzion
Dizzion Managed Desktop as a Service (DaaS) on IBM Cloud can help enterprises build an agile, long-term remote work environment, using cloud desktops to optimize end-user performance, security and compliance.
IBM Cloud Satellite
IBM Cloud Satellite is IBM’s distributed cloud offering. It provides consistency in services and the ability to deploy anywhere. It is a platform service that expands the reaches of IBM Cloud to infrastructures outside of IBM Cloud data centers.
The primary benefit of a bare metal server is best described by which of the following?
The access end users have to hardware resources.
What can users implement for workloads that are running on virtual servers, in order to prevent failovers with multiple virtual servers and will automatically cover for each other during a failure?
Placement groups
Which of the following can be used to set up policies for time-based usage spikes, like over weekends or holidays, and can be used when a company is expecting traffic to spike?
Schedule based scaling
Which IBM Cloud service is the only public cloud service that supports traditional x86 and IBM AIX, IBM System i and Linux on IBM Power applications running together in the same environment?
Skytap
Which type of gateway connects VPCs and on-premises networks through a central hub.
