Network Virtualization Using Generic Routing Encapsulation

1. Description of the service-summary The service that we are going to research and try to incorporate into the organization is cloud infrastructure as a service. We are planning to provide the end user with a well maintained network storage that would be easily accessible from any location while maintaining a secured connection and redundancy of the client data. With the changes in technology and advancements in cloud services, we should be able to save some money for the organization by going to cloud infrastructure services and limiting the maintenance and hardware cost of housing our own servers.We currently house 44+ servers in our service area, most of the servers are being used to less than 30% of capacity while others are reaching a peak 80-90% capacity. The servers house the client’s p: drive (personal data) as well as

Typical data centers can occupy from one room to a complete building. Most equipment are server-like mounted in rack cabinets. Servers differ in size from single units to large independently standing storage units which are sometimes as big as the racks. Massive data centers even make use of shipping containers consisting of 1000’s of servers. Instead of repairing individual servers, the entire container is replaced during upgrades.

Commercial data centers like Equinix and Amazon have to be judicious expanding capacity considering lengthy construction and heavy capital investment. A data center contains aisles and aisles of server cabinets thousands with each costing more than a quarter million containing 64 specialized laptop sized servers essentially a computer. Networking cabinets go together with server cabinets in order to electronically connect any server to another through high-speed fiber cables. The networking cabinets of today consume 25% of the useful floor space for IT cabinets but consist of 40% of the total cost. The data center is clamoring for IT gear that supports a new technology known as Network virtualization to address the conservation of space and

As we all know virtualization is the requirement of future. We have evolved from the age of traditional environment to virtual environment.We have grown accustomed to almost all things virtual from virtual memory to virtual networks to virtual storage.The most widely leveraged benefit of virtualization technology is server consolidation, enabling one server to take on the workloads of multiple servers. For example, by consolidating a branch office’s print server, fax server, exchange server, and web server on a single windows server, businesses reduce the costs of hardware, maintenance, and staffing.

The technology solution that is recommended for the organization is to be provided by VMware. The physical topology of the datacenter consists of x86 virtualization servers, storage networks

As this demand for dynamic and unpredictable data grows, more and more devices have to be added to existing networks and configured accordingly. The need of the hour is to regulate networks centrally and as a whole rather than configure individual network devices and gain more control to achieve flexibility in existing networks.

Across Industry verticals there is increasing adoption of Hadoop for Information Management and Analytics. Many have realized that in addition to new business related capabilities Hadoop also offers a host of options for IT Simplification and cost reduction. Initiatives such as Offloads are at the heart of such optimization. That said, capacity planning is the first step that needs to be carried out successfully for either a IT driven use case or a business driven use case. This paper takes a look at why Big Data processing frameworks such as Hadoop clusters require careful capacity planning for the timely launch of Big Data based capabilities. Additionally, it discusses how capacity planning can facilitate appropriate service level agreement (SLA) guarantees and ensure deliveries within defined budgets. These types of guarantees with sets of standard hardware configuration are the key for effective capacity planning. The key constituent of overall capacity management strategy for the Hadoop eco system is Cluster Capacity Planning. It is this part of the strategy that caters to the troublesome and unavoidable

Scale-out represents one of the most profound shifts in data center deployments we have seen in a generation. This approach represents a more agile and flexible way to drive value while reducing overhead and operational costs. Therefore, scale-out enables organizations to take advantage of hardware efficiencies while leveraging a powerful infrastructure to automate and scale cloud-based workloads across distributed, heterogeneous environments.

The low-hanging fruit comes from the market segments that require a clustering of compute and/or storage devices, namely, High Performance Computing (HPC) and Storage Area Networks. Additional customers will users of cloud Computing and the rapidly growing Edge Computing market.

This white paper will bridge both Cloud Networking and Data Architecture on how it currently fits the organization, WideOpenWest (WOW!) privations. A majority of new organizations are trending to the very popular Cloud networking that can also “join-in” different types of data architectures. Huge corporations are using terms like “Big Data, … a popular term used to describe the exponential growth and availability of data, both structured and unstructured.”(SAS, 2015). Other names include, “data warehousing” or, “data mining”. How is Cloud networking the Data Architecture designed into WOW!’s current IT development, what platform is needed, and when implemented how will it impact on the future of

Scalability is a major requirement for virtual networks. For this reason, virtual link aggregation will constitute an important requirement for network virtualization. Virtual link aggregation can be defined as a set of virtual links that follow a common path and are similarly treated between a pair of virtual nodes. It can be performed by carrying at least two types of identifiers in the data plane, one for virtual network identification and another for hop-by-hop forwarding. Hence, virtual link aggregation enhances scalability and also improves performance.

Key tools utilized, variable length subnet masking and route summarization are explained as well. Here choosing the appropriate routing protocol is equally critical for a successful design. To implement different masks for the same major network it is necessary to have a routing protocol that supports VLSM. Such routing protocols are called classless routing protocols. They carry the mask information along with the route advertisements therefore allowing for the support of more than one mask.

As much as possible of our infrastructure is designed to provide scalable and flexible environment. We work from two data centres, and we have a platform that allows you to easily move the load between the two sites. Repetitive structure, and without affecting our sites, to allow maintenance to be done at the time the majority of the day.

Consolidation of Workloads: In a client server setup, most physical boxes are incredibly under-used because of software limitations or usage capacity. But with Virtualization, resource utilization can be increased by performing load balancing algorithms as the workloads can be placed on a single piece of hardware reducing the number of physical
