Below are the characteristic of oVirt, execpt!
Large scale
Open Source
Using complex deployment
Centralized management virtualization
Below are the advance features of oVirt, except:
Memory page sharing
WDMI - Backthrough
Thin provisioning
Live migration
oVirt can monitor these components, except:
Active Directory File Sharing
Data Centers
Storage Domains
Clusters
These are the benefits of using container, except:
Improved provisioning efficiency
Far less resource overhead
Using Guest OS library, bins, and kernels
Fewer operating system to support and configure
What is one of the security challenge in containerization?
Suitable for all applications
Difficult to isolate workloads
Guest OS optimization
Very balanced systems
What is the benefits of using Docker?
With Scheduling algorithm performances
No need for Hypervisor
No User, No Tenant
SSL Encryption supported
Only work for small applications
In Docker Client, these are the command that you normally use:
docker clone
docker push
docker run
docker build
docker pull
What you really want to know, that Docker is NOT:
A programming language
An open source framework
A container virtualization
An operating system
A virtual machines
Below are the explanation for Docker File, except:
User can create an automated build that executes several command line instruction in succession
A docker file is text document that contains all the commands a user could call on the command line to assemble an image
Docker file is use for automation of work by specifying all step that we want on docker image
Docker file is build in sophisticated way to ensure that security is not the problem
Below are the benefits of Docker, except:
More Apps can be run in single instance
Fast deployment cycle
Application portability
Easier for system admin to maintain
A tool for defining and running complex application with Docker is called:
Docker Hub
Docker Portal
Docker Compose
Docker Build
For a Docker to be able to apply executable permission to the binary using this command:
sudo chown +x /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo cgroup +x /usr/local/bin/docker-compose
sudo userspace +x /usr/local/bin/docker-compose
what is Open vSwitch?
A multiapplication programming using UNIX kernels binary
A multitenant instance for maintaining multi vector
A multiroute protocol for switch based network
A multilayer software switch licensed under the open source Apache 2 license
These are the core components for Open vSwitch (OvS), except:
Communicates with the systems through database server
Communicates with outside world using OpenFlow
Communicates with kernel modul over Netlink
Communicates with ovsdb-server using management protocol
What is Kubernetes:
Management system for multiple virtualization instances
Using google Tensorflow for multigraph
Linux based virtualization with instance performance
Open-source system for automating deployment, scaling, and management of containerized applications
