Week 5 Discussion This is a required assignment worth 20 points (20-points/1000-points). Assignment must be submitted by the due date. No late assignments are allowed. Please discuss the following top

Define and describe a SAN.

A storage area network (SAN) is a network of storage devices that several servers or computers can access, offering a shared storage space pool. Each networked computer will access SAN storage as if it were local disks attached directly to the computer(Jaikar et al., 2016). A few SAN advantages are centralized storage management, rapid data migration, greater scalability, and better data protection and disaster recovery.

Define and describe the NAS.

A network-attached storage (NAS) system is a network linked storage device that enables network users and heterogeneous clients to store and retrieve data from the centralized location. In general, these systems consist of an engine that integrates file services and one or more data storage devices. A few advantages of NAS are remote data accessibility, easier administration, faster data access, and scale-out capacity.

Describe how cloud-based data storage works.

Cloud-based storage allows data and files stored in an off-site location that can be accessed either by a public internet link or a dedicated private network connection. The provider hosts, operate, secures, supports the servers and related resources, and guarantees the user has access to the data whenever they need it (Marzi et al., 2017).Cloud storage provides a new type of distributed storage ware applications configured for maximum availability.The software can also be configured with a dedicated computer without modification to run on a server based on host hardware or virtual machines. Cloud storage helps businesses deliver and retrieve content and application data through cloud infrastructure to users' cloud devices.

List the pros and cons of a cloud-based database.

Advantages:

Scalability: It is possible to quickly and reliably scale cloud-based databases.

Accessibility: Data can be accessed anywhere at any time. Cloud database facilitates fast collaboration and sharing between users in different locations.

Lighter administrative burden: A cloud-based database does not eliminate the function of a database administrator, but it does get rid of specific features that usually occupy the resources of DBA, enabling them to concentrate on more significant tasks.

Disadvantages:

Data breach: Cloud database has taken its new paths of placing data at risk, including cyber attacks

Inflexibility:The database scalability and consistency problem are solved only with a program fix or an extension. However, the locked-down existence of a cloud database can preclude the user from using these solutions.

Downtime: Cloud-based database has a reputation for periodic large-scale outages.
