|
Visualisation |
- Allows you to connect VM's and devices to a network in the same way as Physical devices - Makes it easy to rebuild and build complex networks - No need to purchase expensive hardware - Supports a high number of Virtual networks to one physical network adapter |
|
|
Virtual Switch |
- Allows connections to VM's over separate VLANS - Allows us to separate traffic for Security and QoS - Can also have Virtual Routers, and Virtual Firewalls which can be VM's |
|
|
Software Defined Networking (SDN) |
- There is a control plain, and a forward plain - Control plain, does all the thinking, and the forward plain does the task - Allows the network controller to be programmable - OFP, Open Flow Protocol. This is the foundation which allows building SDN solutions |
|
|
Virtual Network interface VS Physical Network Interface |
- One you can touch and the other you cannot - The IP config is the same - Virtual NIC will be in the host machine, and not attached to host machine, like the NIC you plug a cable into |
|
|
Storage Area Network (SAN) |
- Any high performance network whose primary purpose is to enable storage devices to communicate to PC's and each other - SAN's allows access to share block level data storage - Looks like locally attached storage, like a internal disk |
|
|
SAN Fiber Channel Fabric |
- Often used as the communication protocol in a SAN - FC Fabric is made up of a number of FC switches |
|
|
Jumbo Frame |
- This is a ethernet frame that has a larger payload then 1,500 bytes - This stops systems becoming overloaded with big requests |
|
|
Small Computer System Interface (ISCSI) |
- IP based internet Protocol - Storage networking standard for linking data storage facilities |
|
|
Network Attached Storage (NAS) |
- File Level Storage device - Directly attaches to IP network - Provides data access and storage over IP using File level protocols like NFS and CIFS - Can replace file servers |
|
|
Cloud Computing |
- Provides access to computers, services, applications, servers, network infrastructure and storage on distributed network - Users access these resources via networking and internet protocols |
|
|
Service Models in Cloud Computing |
Three Main Types Infrastructure As A Service (IAAS) Platform As A Service (PAAS) Software As A Service (SAAS) |
|
|
Infrastructure As A Service (IAAS) |
- Bottom layer of cloud computing model focusing on pure infrastructure - Combination of all physical hardware, servers, racks, cooling, networking Ect - Can be used to replace old hardware - Can be used as a Warm/Cold Site - Large computing power |
|
|
Platform As A Service (PAAS) |
- A Layer on top of Physical Hardware - Referring to the virtualisation and OS Layer - Can be used as temp access to OS's - Can be used to Streamline application development - Provider manages installing OS's and system |
|
|
Software As A Service (SAAS) |
- Top layer of the infrastructure - Offers complete applications in the cloud - Hosted emails as a example - Can be used to avoid maintenance - Can be used for testing and trailing applications in the cloud |
|
|
Cloud Computing Deployment Models |
- There are different models for cloud computing - Each describes a way cloud infrastructure is deployed - There is Public, Private, Hybrid and community cloud computing |
|
|
Public Cloud Computing |
- Hosted off site - Owned by third party that sells services to the public in a multi tenant fashion - Available to all members of the public |
|
|
Private Cloud Computing |
- Typically built to be used within a organisation - Must be developed and maintained by a IT team - Providing employees to resources in different locations |
|
|
Hybrid Cloud Computing |
- Combination of different cloud types - Cloud types maintain their characteristics but bond together to form a single service - Example of this could be a organisation migrating from Traditional storage to cloud storage |
|
|
Community Cloud Computing |
- Open and public inter-network that enables clients to find resources on demand - Separates an organisation from cloud resource providers - No contracts and agreements - Lots of organisations host this resource, which is why is can be found on demand |
