2.2 Flashcards
Via the cloud: Iaas, haas, saas, paas, xaas
Infrastructure as a service, hardware as a service, software as service, platform as a service, anything as a service
Managed service provider
Msp help network connectivity, back up and disaster recovery, growth management and planning
Theres also mssp, who firewall, patch, security management
On premises vs off prem
On premises local hardware, seevers in owned data center
Off prem, no in our building, specialized computing environment
Edge and fog computing
Edge- Iot devices (alarm, lighting, climate systems) computed on the device are all occuring on the local system. These devices collect data on the device and make decsions locally
Fog - some devices are distributed on cloud for processing so not all decisions are local, only the needed data. Sensitive data stays local and fog for less secure info
Thin client
A thin computer with only enough power to ru things on a cloud, its connected to desktop in the cloud. No need cpu or ram
Virtualization
Run many diff os on same physical device
One infrastructure, one hypervisor, separate OS, separate app for each virtualization
Containerization
Has infrastructure one host os, one docker, and many diff apps used in separate sandboxes, the apps cant interact with each other
Microservice and api
There are services in each micro services (inventory, report writing) that are attached to databases. One client goes into one api gateway to access one of the micro services
Virtual private clouds
A pool of resources created in a public cloud, many different application clouds, transit gateway is a router in the clouds, that users connect through to then have access to application instances
Infrastructure as code
Describe instances in code to deploy like describing hosts servers that have both mail and dbservers we can use this description of code to deploy other instances, like a blueprint
Software defined netowrking
Separating functionality of network into the control plane (management and ongoing configuration of device) and data plane ( handles operation)
Vm sprawl avoidance
When vms are not used but they aren’t decommissioned, so that we can-free up resources
