Cloud Architecture
This component abstracts physical hardware to allow multiple virtual machines to run on a single server.
What is a hypervisor?
This document defines uptime expectations for a service or services.
What is an SLA? (Service Level Agreement)
This migration method moves workloads with minimal modification.
What is Rehost?
IOPS is used to measure this.
What is disk performance?
This hypervisor runs directly on the hardware.
What is a type 1 hypervisor?
A cloud provider handles patching and runtime management, but the customer deploys code.
What is PaaS? (Platform as a Service)
This metric defines the acceptable amount of data lost after an incident.
What is an RPO? (Recovery Point Objective)
This migration strategy modifies the application architecture for Cloud-native services.
What is refactoring?
This storage tier is best for infrequently accessed files.
What is cold storage?
This type of database uses rows and columns.
What is a relational database?
A company wants to share resources among multiple organizations but maintain logical separation.
What is a community cloud?
The best method for a workload that fluctuates unpredictably.
What is Auto-scaling?
This migration type replaces an on-prem application with a Cloud application.
What is Replacing?
This point-in-time recovery method is used primarily by Virtual Machines.
What is a Snapshot?
This database is optimized for less structured data.
What is NoSQL?
This cloud model allows for controlling the VM, its OS, and all the contents stored on the device.
What is IaaS? (Infrastructure as a Service)
A planning tool to help simulate a workload before deployment.
What is a Sandbox Environment?
A deployment strategy with two environments, one for production and the other for development.
What is a Blue-Green deployment?
Storing data in multiple regions.
What is georedundancy?
This is used to improve query speed in a database.
What is indexing?
The cloud characteristic that allows for a business to only pay for the compute resource time consumed.
What is measured service?
A company that needs 99.99% uptime can have this much downtime per year.
What is 52 minutes?
This deployment strategy rolls out updates to small subsets of users before making it available to all users.
What is a Canary Deployment?
This cloud storage type is best for structured transactional data.
What is block storage?
A standalone virtual option to run a specific service or task.
What is a Container?
