Cloud Computing  is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud Service Models IaaS – Infrastructure as a Service PaaS – Platform as a Service SaaS – Software as a Service Infrastructure as a Service (IaaS) IaaS, as the most flexible of the cloud models, allows your business to have complete, scalable control over the management and customization of your infrastructure. IaaS model is the cloud provider hosts your infrastructure components that would traditionally be present in an on-site data center. Your business, however, would maintain control over operating systems, storage, deployed applications, and possibly limited control of select networking components IaaS was earlier called as Hardware as

IS-IS is a link-state interior gateway routing protocol. Like OSPF, IS-IS runs the Dijkstra shortest-path first (SPF) algorithm to create a database of the network’s topology and, from that database, to determine the best (that is, shortest) path to a destination. IS-IS : Intermediate System to Intermediate System IS-IS as Intermediate System to Intermediate System Unlike OSPF, which was developed and standardized by the Internet Engineering Task Force (IETF), IS-IS is an ANSI ISO protocol and was originally based on the Digital Equipment Corporation DECNET Phase V Network Technology. IS-IS uses a slightly different terminology than OSPF for naming its protocol packets. The packets that IS-IS routers send to each other describing the network topology are called link-state protocol data units (link-state PDUs, or LSPs). In addition to describing the network topology that the router knows about, the link-state PDUs include IP routes, checksums, and other information. Similar to

Types of area networks – LAN, MAN and WAN LAN - MAN - WAN "Local Area Networks," or LANs, and "Wide Area Networks," or WANs, can both be defined by the network protocols that constitute them. Protocols are standards that define how data is ultimately transferred from one system to another. The difference between a LAN and a WAN is the distance the data travels, with a LAN typically serving a single building and a WAN usually covering different geography locations. There are other types of Computer Networks also, like : PAN (Personal Area Network) SAN (Storage Area Network) EPN (Enterprise Private Network) VPN (Virtual Private Network) Local Area Networks The terms Local Area Network (LAN) and Wide Area Network (WAN) are general descriptions of geographic size of the network and to some extent, the protocols in use.  The acronym LAN tends to be used to refer to a network that encompasses a single room or a
