High Availability and Disaster Recovery Concepts
For my group blog I choose to explain high
availability and disaster recovery concepts ands chose the best solution. To help
everyone understand better here is some back knowledge, high availability is
the process of an application, operating system or component of a system that
can operate at a high level continuously for a long period of time without failure.
Disaster recovery is a set of procedures and policies that act when a natural
or human inflicted catastrophe are caused to an important technological infrastructure.
To understand what method is better
to choose we have three factors to look at: switches, routers, and firewalls.
Switches are physical
electrical components that when are open allow network traffic from one device
to the network, but when closed stops the flow of signal.
Routers are used in
the same concept of a switch but can connect two different networks together from
further differences, and routers traffic in the most efficient way.
Finally,
we have firewalls. A firewall’s purpose is monitoring the incoming and outgoing
traffic on a particular network based on pre-established security policies.
I believe the best solution for high ability would be
routers because they are designed to help with more bandwidth and networks. I believe
the best solution for disaster recovery would be firewalls, because they help
prevent catastrophe with the preset security features.
