Q

explain what you can about the term DevOps

A

this is the joining of the word development and operation. It is the cycle of continuous delivery where developers must use past data of the current version of software to run tests which would have been collected by the operations team who continually monitor and track the software performance. The operations team might also suggest ideas for an update after they have been monitoring the software

Q

explain what a hybrid cloud is

A

this is a cloud that joins two or more cloud types together. For example a business might choose a private cloud for sensitive data but also have a public cloud for more general data this gives them more control over their data while at the same time reaping the benefits of public cloud

Q

what are 3 considerations of cloud usage

A
  1. Latency - to minimise latency a customer needs to be close by to the data centre there data is being held in
  2. Climate - the climate that the data centres are built in directly affect there maintenance and environment factors (I.e humid or hot environments need dehumidifiers or air conditioning constantly)
  3. Control over data - some customers worry about which country has jurisdiction over their data and so ask to know exactly where their data is being held
