Week 3 - Managing Cloud Resources Flashcards
How involved is a user when using SaaS?
Software as a service, a user isn’t deeply involved as everything is already pre-configured
How involved is a user when using IaaS?
Infrastructure as a service, a user is hosting their own services in the cloud and decides how they want the infrastructure to look, what to run
What’s a region?
a geographical location containing a number of data centers
What are the geographical locations of regions called more specifically?
zones
Why are zones in different regions important?
If one zone fails the other data centers are still available to migrate services and won’t affect users
What are the 3 types of common clouds?
- Public
- Private
- Hybrid
What is autoscaling?
Increase the VMs used when there are a lot of queries and shut down VMs when the number of queries goes down (creates new instances)
(the service owner only pays for the cost of machines in use at any time)
What are the 3 common cloud services?
- SaaS
- PaaS
- IaaS
What are the 4 main types of cloud computing?
- Public clouds
- Private clouds
- Multiclouds
- Hybrid clouds
What is cloud computing?
Cloud computing is the delivery of computing services (like IaaS)
What are 4 additional cloud services?
- VPNaaS
- FaaS function as a service (event-based service)
- DaaS data as a service (organizes data companies generate
- BaaS blockchain as a service uses encrypted connected blocks of information for high-security documents
For autoscaling, where is the data stored?
Since the number of systems in use will vary to handle traffic, the data for the cloud instances can be stored in a database or in separate drives
What is load balancing?
Distributes the load among many servers
