The Use Of Optical Cables and Optical Fibers In Data Center

 

 Structured cabling system DPC (Data Center) should support the work of various applications, including those that are only planned to use in the future. Speed in data centers are increasing due to the use of server virtualization technology and the use of this technology leads to an increase in requirements for the cable system. Using an optical cable in data centers is primarily due to the fact that a large number of reliable and working technologies and solutions that use as a medium for data transmission singlemode and multimode fiber , the transmission of large information flows and the distance is much more than it can reach copper cables.

Optical cables have no problems with EMC and crosstalk occurring between the twisted pairs and copper cables, which makes use of copper cables in data centers .

The diameter of the optical cable is less than copper and it allows the use of cable channels for the optical cable of smaller sections, which allows better use of space in data center, reduce the costs of cable channels. Also reduces the load on the mount cable channel.

Cloud Classification

 

In meteorology there is a detailed classification of clouds, numbering at least 12 species. IT professionals do not lag behind in this regard- they can conventionally distinguish several categories of “cloud services“.  It should be noted that the conventional classification generates a certain amount of confusion in concepts, so it’s important to give at least a brief description of categories.

There are three major types of cloud-based technologies: SaaS; software as a service, PaaS; Platform as a Service and IaaS: infrastructure as a service.

SaaS Model – A lease of the software, which is developed by the service provider, and the user can access it via the Internet. This model allows us to reduce the cost of implementation and maintenance of software. A striking example – popular with the U.S. system of Customer Relationship Management Salesforce.com. Paying for its services in proportion to consumption, you can use the ready business process for working with clients. This completely eliminates the need for costly implementation of the system in operation.

PaaS Model involves the provision of a platform as a service, for example, to develop or test software. Thus, any organization can get the missing computational resources for the development and subsequent operation of their own applications. Google App Engine is one of the leaders in such services.

Advantages and disadvantages of SaaS and PaaS

 

Below I detail what I understand about the advantages and disadvantages of SaaS and PaaS, and of course what influences decision making in business. To a greater or lesser extent all these relate to paas saas and therefore I have chosen not to separate them.

Advantages:

Less initial investment and less risk, the use of the software without having to make an initial investment in machinery, software base (so) and additional software to run the application they would need in an environment in-house, is an important benefit for IT managers and ultimately for the company.

Cost reduction, in addition to paying for only what you need, you get a cost savings of maintaining the platform of machinery and the necessary software (databases, application server) to run your application.

Immediate updates and new features , a party that will not require dedicated staff for updates and software upgrades immediately. Sometimes we choose to use new features.

Support more agile and quick implementation. Bugs have a direct treatment and commissioning solution faster than in-house facilities.

The company focuses its efforts on your business , you really are outsourced to the point that systems do not expend effort in the choice and maintenance of systems.

However, always require care dept. IT but to a much lesser extent.

Increased availability and data security, against what may appear and in view of the disadvantages that we will see below, many companies have no procedures for backup, restore and general contingency plans in case of loss of information or hardware failure.

What is Web Hosting in the Cloud?

 

Web hosting in the cloud computing or cloud hosting is the future of web hosting.

 

The cloud formed by several servers linked together to form a single platform. Because there are a lot of servers working together instead of one, load balancing, increased capacity, and minimizes the likelihood of failure.

Unlike shared hosting servers, where data is stored on a single server, web hosting in the cloud sits on a network server, so if one server fails, or if the hard disk of a server fails, the site is not affected, because their data is mirrored on other servers., is “balancing” their workload between the “cloud” of servers and information is replicated to other servers, so that the user not experience cuts in access to web pages.

This means that in uptime (time that the site is accessible to users) is virtually 100%. The real uptime of a server cloud is around 99.99%.

The fact that abstract information from the physical part is what has given name to this type of web hosting in the cloud (cloud hosting) as the data is supported by multiple servers intertwined, and are more immune to breakdowns a server.

Another advantage is cloud servers scalability. If at any point of time, a site needs more resources for an increase in visits is not limited by your hardware, and can use the resources of the cloud server.

Basics : Cloud Computing

  

Cloud Computing has become a buzzword now a days in the hosting industry. With the advancements in it companies like Google and Microsoft has extended their search/ investigations towards cloud computing. One of the hottest trends in small business and enterprise-sized IT is cloud computing. Cloud computing represents a major shift in the way companies view their technology infrastructure. In this post I am gonna explain some basics of cloud computing as to understand it in a more simplified way.

Cloud Computing is one of the hottest trends in the industry. This has proven as a bliss for small business and enterprise-sized IT. Cloud hosting has considered as the major shift in the way companies use to look their IT infrastructure. This type of approach to IT relies on the Internet, and usually involves provisioned, scalable, dynamic and virtual solutions. Cloud computing pulls the details of IT infrastructure management away from the business and puts it squarely in the hands of true experts.

Cloud has been used as the metaphor for the internet computing. This can be categorized into SaaS(service as a software), IaaS ( Infrastructure as a service) & PaaS (Platform as a Service). While SaaS is by far the most common type of cloud computing implementation today, other types are rapidly gaining popularity as companies see the cost and expertise advantages of each. It also make use of  Web 2.0 and other virtual technologies, applications are provided to users via the net with the data stored on the provider’s servers.

7 Reasons Why Small And Medium Businesses Adopt Cloud Computing

 

The concept of cloud computing services is growing between the departments of information technology. According to a survey, 98% of respondents said that the cloud is no longer seen as a passing fad and that the concept is here to stay. In Asia, India is an example of this growth, according to this study, the country tops the list with 20% of medium and large sized companies that already have some application in the cloud. For small, the scenario is still a little different.

According to projections, the number of adherents to the cloud applications are expected to grow between 30% and 35% in the next two years. Being a simple solution to online backup services or outsourcing, the use of cloud computing is an unavoidable reality, especially for small and medium enterprises, which may use it according to demand and pay for what they use, all with security, reduce costs and without worrying about infrastructure, web applications, web professionals and maintenance.

Thinking about it, company that specializes in cloud computing and outsourcing, has the seven main reasons for small and medium businesses that adopt cloud computing.

The Concept of Mobile Data Centers

 

Data Center (DC) is becoming one of the main points of the efforts to increase energy efficiency in IT and telecommunications. “Green” technology increases the cooling efficiency, reduce losses and allow the use of alternative energy sources. In turn, this leads to a rapid replacement of traditional technologies in the data center to new, with improved energy efficiency, as well as the development of new product niches, such as container, or as they are called mobile or modular data centers (MDC). The fact that the dimensions of mobile containers should allow their transport by road and rail. In addition, they must be strong enough to withstand the loading and unloading and delivery in a complete state. There must be a constructive element for operation and maintenance (air, cable entry, the passes of sufficient width, etc.). These requirements can be satisfied through the use of standard shipping containers (20 and 40 feet).

 

Generally speaking, the concept of containerized data center is very attractive. After all, this solution provides organizations with limited resources, to increase their computing capacity without building a new data center. All tested and debugged the IT data center equipment can be placed, for example, a standard container of ISO, which can only be installed in the right place and connect to the cooling system (water), electrical power and communication channels. However, according to IDC, the market of container data centers is still small. However, the market is growing rapidly. A key feature of its data centers became the third generation modular approach. The concept of novelty under the name of IT PAC (IT Pre-Assembled Component) involves small independent mobile containers that are going off-site data center and can be connected together to form a holistic data center.

Adopting Infrastructure as a Service Can be a Good Deal

 

Analyzing the Indian companies from 2005, we can notice a big paradigm shift in relation to the culture of proprietary technology equipment. This means that there was breach of the resistance option of renting rather than buying. With credit difficulties, especially with the 2007 crisis, corporations were forced to see new possibilities. Then we noticed that the model called Infrastructure as a Service (IaaS) fit in nicely in this new scenario, because in addition to efficiency, it is quite functional from the financial point of view.

Today, many major companies already work under the IaaS model. In fact, we are living the beginning of time to the glory of IaaS and believe that the peak demand will occur in the coming years, given the economic growth of the country and the sporting events to be hosted here.

Regardless of how they are being organized, these events are already forcing Indian companies to fit in physical infrastructure. We will need new airports, stadiums, bridges etc. These works require a strong back office, for companies providing services need to quickly assemble IT environments with flexible services. Our restructuring economic environment is enabling companies to see themselves with the plans in the long run. This brings some comfort and optimism to our area.
