several minutes to several days to make the data available to access
Hot Storage - ✔Refers to the data that is readily available at all times.
Key performance characteristics of cloud storage - ✔Data read/write speed
Storage Compression and/or deduplication
Data Encryption
Storage capacity limits
Direct Connect - ✔If a company needs to make extensive use of cloud services and have a very
little delay, a ________________ between that company's network and a CSP's network might
be the best option.
AWS CLoud adoption framework CAF - ✔Outlines six perspectives you should consider
