Server
A server is a computer or computer program which manages access to a centralised resource or service in a network
Benefits of a server
- A server improved collaboration
* A server adds reliability
Drawbacks of a server
- Purchasing the network cabling and file servers can be expensive
- Managing à large network is complicated , requires training and a network manager
Storage virtualisation
The pooling of physical storage from multiple network storage devices into a single storage device that is managed from a central console
Commonly used in storage area networks
Benefits of storage virtualisation
- Allows you to more easily manage heterogenous storage environments
- The overall system may have a slightly higher latency
- Allows you to migrate data between drives more easily
Drawbacks of storage virtualisation
- High costs of implementation
- It creates a security risk
- Creates an availability issue
Cloud computing/storage
Cloud storage is a cloud computing model in which data is stored in remote servers accessed from the internet or the “cloud”
Benefits of cloud computing/storage
- Usability - allows users to drag and drop files between the cloud storage
- Accessibility - Stored files can be accessed from anywhere via internet connection
Drawbacks of cloud computing/storage
• Accessibility- If you do not have an internet connection then you will not be able to access your files
Hybrid servers
A hybrid hosting service of hybrid server is a type of internet hosting which is a combination of a physically-hosted server with virtualisation technology
Examples: Databases, file storage, commerce applications
Benefits of hybrid servers
- Cost saving
- Improved security
- Enhanced organisational agility
- Greater Accessibility
Drawbacks of hybrid servers
- It takes tools and skills to operate a hybrid virtualisation
- The cost of starting and building the hybrid is very high
- Compatibility - Many public servers don’t support hybrid
- The security for one part of the hybrid is under attack
Desktop virtualisation
Desktop virtualisation can be used in conjunction with application virtualisation to provide a comprehensive environment management system.
Hypervisor
A computer software, firmware or hardware that creates a runs virtual machines
