Module 2 Flashcards
Four types of virtual server offerings in IBM Cloud
virtual server service, bare metal service, power system service, and hyper protect service. The features and capabilities of each virtual server are shown here.
Virtual servers
offer a range of operating systems and configurable random-access memory (RAM) and processing power.
Bare Metal Servers
provide horsepower for processing intensive and disk input/output (I/O) intensive workloads.
Power system servers
are used to deliver flexible compute capacity for power system workloads.
Hyper Protect Servers
allow for the creation and running of virtual servers on IBM LinuxONE(most secure Linux-based platform) and provide access to Z technology without purchasing any unique hardware or having unique Z skills. They offer added security as the servers are deployed in any secure service container. They are as easy to configure and deploy as any other virtual machine but can only be deployed to specific data centers in Dallas, Frankfurt, Sydney, and Washington.
There are three types of block and file storage related services on IBM Cloud
Block storage service, file storage service and cloud storage service
Block storage service
provides virtual servers and bare metal servers with SAN-like Internet Small Computer Systems Interface (iSCSi) storage.
File Storage Service
rovides virtual and bare metal servers with a network file system (NFS) based storage.
Cloud Backup Service
is an enterprise level backup storage and disaster recovery solution.
IBM Cloud has two different services for networking:
- Cloud Internet Services (based on Cloudflare)
- Collection of networking infrastructure services with options for virtual local area networks (VLANs), virtual private networks (VPNs), and content delivery networks (CDNs)
Cloud internet services
Cloud Internet Services provides reliable, secure options for internet-facing application by leveraging Cloudflare. Cloudflare is a web infrastructure company that provides domain name system (DNS) services to 12 million websites and has over 165 points of presence all over the world.
CDN
A CDN is a highly distributed platform of servers used to help minimize delays.
Load balancer
A load balancer is used to distribute traffic among virtual servers.
Virtual private cloud
A Virtual Private Cloud (VPC) is a secure, isolated, private cloud hosted within a public cloud. A VPC provides the security of a private cloud with the cost effectiveness and scalability of a private cloud.
VMware Solution Dedicated
The VMware Solution Dedicated is a single tenant, bare metal solution with vCenter Server and VMware vSphere options, which allows clients to retain root level access to the hypervisor.
VMware Solution Shared
VMware Solution Shared allows for deployment of workloads on top of IBM hosted VMware infrastructure. IBM provides a self-service on demand VMware cloud computing platform with VMware vCloudDirector running on IBM Cloud. IBM manages up to the hypervisor level.
Which compute option on IBM Cloud are the Citrix, VMware, and Cloud Linux images associated with?
Bare metal
Which compute option on IBM Cloud offers access to Z technology without requiring the purchase of Z hardware or requiring Z technology specific skills?
Hyper Protect Service
Which virtual server instance is billed hourly and monthly?
Public virtual server
Which IBM Cloud service provides virtual servers and bare metal servers with SAN-like iSCSI storage?
Block storage
What is the maximum storage volume supported for block or file storage on IBM Cloud virtual and bare metal servers?
12TB
All these services are provided by IBM Cloud Internet Services EXCEPT
Auditing is not provided by IBM Cloud Internet Services.
Which network infrastructure service is used to distribute a workload between multiple servers?
Load balancer
Which service can assist a client in connecting an application in IBM Cloud with their private network?
VPN
