`dig` command stands for **D**omain **I**nformation **G**roper. It is used for retrieving information about DNS name servers. It is mostly used by network administrators for verifying and troubleshooting DNS problems and to perform DNS lookups. It replaces older tools such as `nslookup` and the `host`. |
||||
|
||||
It has the following syntax: `$ dig [server] [name] [type]` e.g. `$ dig roadmap.sh` |

# Data Management |
||||
|
||||
Data management is the key element of cloud applications, and influences most of the quality attributes. Data is typically hosted in different locations and across multiple servers for reasons such as performance, scalability or availability, and this can present a range of challenges. For example, data consistency must be maintained, and data will typically need to be synchronized across different locations. |
||||
|
||||
Additionally data should be protected at rest, in transit, and via authorized access mechanisms to maintain security assurances of confidentiality, integrity, and availability. Refer to the Azure Security Benchmark Data Protection Control for more information. |

Good design encompasses factors such as consistency and coherence in component design and deployment, maintainability to simplify administration and development, and reusability to allow components and subsystems to be used in other applications and in other scenarios. Decisions made during the design and implementation phase have a huge impact on the quality and the total cost of ownership of cloud hosted applications and services. |
