5 Ways a Cloud Can Save You a Fortune – Part 2

Reason No. 3

Fully utilize your hardware with better resource management. Virtualization significantly increases the value of your physical server hardware. Instead of having 5 servers that average 10% CPU utilization, you can virtualize the 5 servers on one physical server, sharing the resources. This decreases rack space, power usage, and is easier to manage. This also allows you to create copies of your servers and have them up and running very quickly, now that they have been virtualized. If you have the proper resource management tools installed on your server, you can automatically allocate the appropriate resources to a server when it needs it or turn off unused servers during low usage; an extraordinarily powerful and efficient way to manage your servers.

 

Reason No. 4

Virtual servers combined with a SAN allow for improved protection against disasters. When you connect a SAN to your private cloud, incredible redundancy can be achieved. Not only can you load balance between servers, automatically shifting server resources between servers on the fly, but in an N+1 environment (having at least 1 extra server than absolutely necessary), you can shut down one server without causing downtime. Imagine performing maintenance on your server like adding more RAM, replacing a hard drive, or upgrading software, without experiencing any downtime. When configured correctly you could power off one server and it would automatically shift the virtual servers over to an available server in your cloud. Taking your disaster protection up one level, you could have another SAN in another data center and perform SAN to SAN replication for a hot site DR environment capable of full recovery in less than an hour.

Reason No. 5

Switching to private cloud computing will save you time and money. The best part about a private cloud is that not only do you get all of the great benefits of virtualization and security, but it can be cheaper and less of a hassle then hosting your own servers or buying dedicated servers. If your company has more than 2 servers, it could benefit from virtualization. If your company has more than 10 servers, it could benefit from private cloud computing with a dedicated SAN and multiple physical host servers. The public cloud revolutionized Information Technology forever; the private cloud brings the benefits to the masses.

Conclusion: Save Money, Save Time, Sleep Easy: Transition to Private Cloud Computing

The private cloud is still a relatively new concept, but is based on some technology that has been around for a while and has proven itself for years. Besides providing some tremendous benefits of pooled computing resources and virtualization, it maintains the security and reliability of a normal dedicated server. The private cloud is not for everyone but a managed data center operator can make the transition to private cloud computing an affordable process and enable you to fully experience all of the great benefits of the private cloud.

5 Ways a Cloud Can Save You a Fortune

One of the biggest IT buzz words of the past few years, “cloud computing” has brought incredible promise to the world of information technology. Cloud computing interest has led to widespread curiosity and awareness of public cloud services.

Features Tailored with Shadow

Pooled computing resources, divided and allocated to different users, have been proven in the development and testing realm of IT to have tremendous benefits. Those benefits however have been overshadowed by concerns of a lack of security and uptime assurances among Enterprise IT executives.

Private Cloud Goals

The private cloud aims to lessen, if not eliminate, those concerns by dedicating exclusive hardware to each user. Instead of your data being stored off “in the cloud” somewhere, one can point to a group of servers in a data center and say, “that is your data, and only your data, on those servers,” alleviating security concerns. It is a “best of both worlds” solution that can bring important benefits like improved uptime and reliability at a lower cost than on traditional IT infrastructure.

5 Ways a Cloud Can Save You a Fortune

That is why I compiled the top 5 reasons why your company should rethink your IT infrastructure and look into the benefits of private cloud computing.

Reason No. 1

Dedicated hardware means increased security. Much like a dedicated or collocated server, the security of your private cloud depends on a variety of factors. However, if you have the proper physical security, anti-virus software, and firewall rules in place, you can rest assured your data as safe as if it were sitting right next to your desk. With a private cloud, you know where your servers are located and that the proper physical and network security is in place. You can meet and talk to those in charge of providing support for your hardware and come visit it if you like.

 

Reason No. 2

The transition from physical to virtual servers leads to better flexibility. This is one of the most alluring benefits of cloud computing. The ability to spin up and tear down a server in a matter of minutes is incredibly powerful and useful. No longer is there any wasted effort in trying to size a server beforehand when you can create a server on the fly. Need more disk space? More RAM? More CPU? No problem. With private cloud computing, you can reallocate resources in moments without worrying about finding a physical server that will have the resources your new server needs.

What is a Private Cloud?

A private cloud is a particular model of cloud computing that involves a distinct and secure cloud based environment in which only the specified client can operate. As with other cloud models, private clouds will provide computing power as a service within a virtualised environment using an underlying pool of physical computing resource. However, under the private cloud model, the cloud (the pool of resource) is only accessible by a single organization providing that organization with greater control and privacy.

 

Cloud like a Pool?

The technical mechanisms used to provide the different services which can be classed as being private cloud services can vary considerably and so it is hard to define what constitutes a private cloud from a technical aspect. Instead such services are usually categorized by the features that they offer to their client. Traits that characterize private clouds include the ring fencing of a cloud for the sole use of one organization and higher levels of network security. They can be defined in contrast to a public cloud which has multiple clients accessing virtualised services which all draw their resource from the same pool of servers across public networks. Private cloud services draw their resource from a distinct pool of physical computers but these may be hosted internally or externally and may be accessed across private leased lines or secure encrypted connections via public networks.

The additional security offered by the ring fenced cloud model is ideal for any organization, including enterprise, which needs to store and process private data or carry out sensitive tasks. For example, a private cloud service could be utilized by a financial company that is required by regulation to store sensitive data internally and who will still want to benefit from some of the advantages of cloud computing within their business infrastructure, such as on demand resource allocation.

 

Features and Benefits of Cloud

The private cloud model is closer to the more traditional model of individual local access networks (LANs) used in the past by enterprise but with the added advantages of virtualization. The features and benefits of private clouds therefore are:

Higher Security and Privacy

Public clouds services can implement a certain level of security but private clouds – using techniques such as distinct pools of resources with access restricted to connections made from behind one organization’s firewall, dedicated leased lines and/or on-site internal hosting – can ensure that operations are kept out of the reach of prying eyes.

 

More Control

As a private cloud is only accessible by a single organization, that organization will have the ability to configure and manage it in-line with their needs to achieve a tailored network solution.

 

Cost and Energy Efficiency

Implementing a private cloud model can improve the allocation of resources within an organization by ensuring that the availability of resources to individual departments/business functions can directly and flexibly respond to their demand. Therefore, although they are not as cost effective as a public cloud services due to smaller economies of scale and increased management costs, they do make more efficient use of the computing resource than traditional LANs as they minimize the investment into unused capacity. Not only does this provide a cost saving but it can reduce an organization’s carbon footprint too.

 

Improved Reliability

Even where resources (servers, networks etc.) are hosted internally, the creation of virtualised operating environments means that the network is more resilient to individual failures across the physical infrastructure. Virtual partitions can, for example, pull their resource from the remaining unaffected servers. In addition, where the cloud is hosted with a third party, the organization can still benefit from the physical security afforded to infrastructure hosted within data centers.

 

Cloud Bursting

Some providers may offer the opportunity to employ cloud bursting, within a private cloud offering, in the event of spikes in demand. This service allows the provider to switch certain non-sensitive functions to a public cloud to free up more space in the private cloud for the sensitive functions that require it. Private clouds can even be integrated with public cloud services to form hybrid clouds where non-sensitive functions are always allocated to the public cloud to maximize the efficiencies on offer.

Business Cloud Have a Silver Lining?

Cloud computing has arrived and cemented its place in the world of web hosting giving businesses no choice but to analyze its offerings and contemplate adopting the solution. Low costs and any easy startup are luring customers in their thousands, but there have inevitably been some criticisms and concerns voiced that urge users to consider a number of factors before investing in the phenomenon.

 

Are the Threats Real?

Should these worries really put businesses off though? A widely believed opinion is that large corporations have the finance to adapt their cloud solutions to meet their needs and requirements but for small to medium enterprises (SMEs) the cloud can sometimes bring a storm. But ultimately every situation is different, so it is important to investigate what cloud computing can do for your business, taking into account your budget, resource needs and security requirements.

Security management, data privacy and performance are just a number of the cloud’s functions that have been called into question, causing some businesses to shift back to self-hosted solutions from the hype-surrounded cloud.

For SMEs it is wise to consider the pros and cons before opting for the solution simply because larger businesses are doing so. The capital investment required to employ cloud hosting is a substantial attraction, as is the low level of maintenance required. Also, the cloud allows smaller companies access to resources they would not receive from other hosting solutions. These are great attributes for a smaller company, but as with most services and solutions there are reported drawbacks and concerns.

Security is a priority for every business, as problems related to this can cause implications to reputations, financial problems and invite legal proceedings. A common concern for those considering the cloud is that hackers may be able to access data. Ultimately it will be on the business to ensure its provider has sufficient security in place along with taking measure to keep data secure yourself such as hardware protection.

Through using a cloud provider, you also will not have control of how your data is backed up or where it is stored, so remember to take this into account before opting for the solution. While these security problems have a possibility of occurring, overall, it is however, unlikely that you’ll experience them and remember that no hosting solution is perfect, but this one is getting pretty close, especially with so many developments occurring on a regular basis.

 

Windup

Downtime and security issues may be a concern for businesses but overall, these are minor drawbacks and certainly don’t counter the advantages of a low capital investment. The “ifs” and “buts” associated with the cloud can be applied to any form of web hosting. It is important to ensure your provider offers resources and services that suit your business needs.

Fly to Cloud! A Step from VPS – What You Should Know?

With an increased popularity of cloud hosting, many users decide to transfer their data to the cloud. Moving from virtual private server (VPS) to a cloud hosting platform is a smart decision that you can make, and this article will tell you why!

What Is Cloud Hosting?

Cloud hosting, also called clustered hosting, because the hosting is spread between multiple connected servers. This loose network is referred to as the cloud. This can be confusing because the Internet at large is also called the cloud, since that is what enables the practice of cloud computing to be done anyway.

Few Cloud Advantages over VPS

If you are on a VPS, you have probably faced such problems as automatic outages and server connectivity problems. With cloud, you can forget such matters. Unlike VPS, cloud hosting gives you something called an automatic failover. If your cloud faces any sort of trouble it will be automatically restarted in another portion of the cloud. In this way, you do not have to worry about the security and availability of your data as it will be available at any time.

Elasticity

Cloud storage is the solution that accomplishes the goal of scalability – you can scale up and down the space needed for your data and you only have to pay for what you use.

Customization

Completely scalable resources is one of the top benefits of the cloud – but some businesses want to get more detailed with their server setup. Cloud have this covered up too. You can adjust all sorts of different attributes of your space, upload and download times, applications and much more as cloud offers full customization.

Cost Efficient

Price is also an important factor of moving from VPS to the cloud. With VPS you have to purchase a pre-determined amount of space and then you are stuck at that exact price level. However, if you end up needing less space, you will have to pay more. However, cloud hosting lets you scale down when necessary, saving you extra money.

Accessibility

Probably the most attractive thing of cloud is that you can have access anywhere and at any time. You can just simply pull out your personal device and check if everything is performing as you want it to. It is convenient too, because you can send and receive emails or use it for any other business purposes.

Final Thoughts

Do not hesitate if you want to switch to cloud hosting – it is a very popular and widely used technology that helps manage your business easier, cheaper and in a more convenient way.

How People with Disabilities Use the Web: Overview

Nowadays, as the usage of the Internet is on its peak, website owners have to do everything to be better than the others. Ones are creating some interesting content, others use eye-catching media, but sometimes they forget the minority of web users – those with disabilities. This resource introduces how people with disabilities, including people with age-related impairments, use the Web.

This resource will describe some basic tools and approaches that people with different kinds of disabilities use to browse the Web and the design barriers they encounter on the Web. I hope it helps developers, designers, and others to understand the principles for creating accessible websites and other web tools.

Web accessibility aims to improve access to the web for people who have any disabilities, which include:

Blindness and poor eyesight. Blind people basically use their hearing to surf the web. The web for such people must have proper website code with HTML code providing textual equivalent to visual information which converts it to sounds. Also, there is some access software where blind people can access text-to-speech information or use the text-to-Braille hardware.

Poor eyesight or color blindness can be a major obstacle in accessing any content. To make your website accessible for such people you should make an option with enlargeable text and images that can be easily understood by people with poor eyesight. Moreover, clickable links, underlined and bolded words also enable people with color blindness to understand information even if it is communicated in colors.

Mobility disabilities such as difficulty to use hands, loss of motor skills, etc. make such people face some difficulties to the web content itself. However, if websites are coded in a way that people have an access and can navigate via keyboard or single switch device, people with mobility disability can easily browse the web and access information just like every other person.

Epilepsy. If your website has some flashing effects, this can trigger seizures in epileptic people. What you must do is to put a prior warning for people with epilepsy or an option to turn off any flashing effects.

Cognitive function and intellectually disabled people have their memory, attention, ability to learn and problem solving skills affected. They often face up with some difficulties where they need to understand the communicated information because of the complexity of the website design or its content. Creating a  friendly navigation for the users and easier readability or color contrast can help them browse the website and understand any content on it.

Many popular websites still remain inaccessible for disabled people but increasing the awareness of web accessibility for disabled people can help them integrate to the society easier and make their life just like every other person. 

Most Expensive Domain TLDs – Price Boost Explained

There are load of different domain name extensions to choose from. However, when you take a look at domain price list, you can notice that some of them are more expensive than other. Why does this happen? What are the most expensive Domain TLDs?

According to the statistics of most expensive gTLDs, the world’s giant Google purchased the .app domain for 25 million U.S. dollars. Then the second place goes to .tech which was sold for 6.76 million U.S. dollars and the third place – .realty which was valued 5.59 million U.S. dollars.

Now you wonder why these TLDs domains are so expensive? There are some major factors that determine the domain name pricing. First one is the registry price which is the price a domain registrar is charged by the registries. The charge for domain varies according to the registrars operational cost, depending on if it is a community-driven organization or regulated by the government.

Second reason why some TLDs are more expensive is because of the restrictions and exclusivity. Some organizations that have domain extensions intend to be exclusive so they choose creative domain extensions. They don’t want that any other company would be able to use it. As TLD can be intended for a specific group like such famous company as .apple, .bmw, or a professions like .lawyer, .marketer, the price rises depending on the need of such TLDs. To register domains with these TLDs, you have to meet some exact criteria and pay a higher price than for example .com or .net.

What is more, support cost is also important for the price boost of TLDs. Some top-level domains have special registration procedures and you need to fulfill some requirements for name changes. Some registries are not as big as other and also not very automated so it takes more time and work to manage the domains there. You may also be asked to pay an additional support cost into the yearly registration fee as well.

There are some different factors that can influence the price for domains. Choose the one you like to make your business on or services that are more recognizable and exclusive.

FreeBSD Operating System – Success or Fail?

What Is FreeBSD Operating System?

FreeBSD is a free Unix-like operating system descended from Research Unix via the Berkeley Software Distribution (BSD). Although for legal reasons FreeBSD cannot use the UNIX trademark, it is a direct descendant of BSD, which was historically also called “BSD Unix” or “Berkeley Unix”. The first version of FreeBSD was released in 1993, and today FreeBSD is the most widely used open-source BSD distribution, accounting for more than three-quarters of all installed systems running open-source BSD derivatives.

FreeBSD has similarities with Linux, with two major differences in scope and licensing:

  • FreeBSD maintains a complete operating system, i.e. the project delivers kernel, device drivers, userland utilities and documentation.
  • While Linux delivers kernel and drivers only and rely on third-parties for system software.

FreeBSD source code is generally released under a permissive BSD license as opposed to the Linux GPL.

Due to its permissive licensing terms, much of FreeBSD’s code base has become an integral part of other operating systems such as Juniper JUNOS and Apple’s OS X.

FreeBSD Hosting

Let’s take a look at CloudSigma FreeBSD servers and by doing that, it will be easier for me to explain to you, why FreeBSD OS is success and not a failure.

CloudSigma offers its customers FreeBSD hosting on their cloud servers with full root access, open software and networking layers, full customization of cloud infrastructure, high performance and more. With CloudSigma, You will immediately notice the difference when using cloud servers compared with traditional Virtual Private Server (VPS) hosting. Unlike most general VPS providers who are dividing large dedicated servers and sharing them between their customers, they run a fully isolated FreeBSD cloud server for you. VPS providers rely on various technologies to isolate many users on a server from one another whilst at the same time using one shared instance of FreeBSD. CloudSigma platform allows every user to run their own full FreeBSD cloud server with full root access. This provides a wider choice of server types, deeper configurability, better performance and stronger isolation and security guarantees.

So, FreeBSD Operating System – Success or Failure?

Darwin, the core of Apple OS X, includes a virtual file system and network stack derived from the FreeBSD virtual file system and network stack, and components of its user space are also FreeBSD-derived.

Some subscription services that are directly based on FreeBSD are:

WhatsApp – processes 2 million concurrent TCP connections per server.

Embedded devices and embedded device operating systems based on FreeBSD include:

 

NetApp’s Data ONTAP 8.x and the now superseded ONTAP GX (only as a loader for proprietary kernel-space module)

Netflix’s Open Connect Appliance to handle content delivery.

The PlayStation 3

The PlayStation 4 (“Orbis OS”).

 

Looking at all of that, how can you say that it is a failure? Definitely a success.

Main Steps to Transfer Data to the Cloud

While there are many reasons why moving to a collocation data center facility is good for the business, the process is still fraught with risk.

My advice is that IT executives should ensure that the contract between their organization and the cloud provider is such that the organization is the stated owner of the data. However, this only takes things so far – it still leaves the issue of what to do with the data after and how to transfer all that big amount of data to the cloud.

The Difficulties of Moving Data into the Cloud

Like all big things, it would take a great deal of work to move big data from one point to another. Let’s now try to get a handle on how large these data sets can be.

Almost all sectors in the United States have, on average, hundreds of terabytes of data stored per company. Many companies have even already exceeded the 1 petabyte mark. The volume of data is growing at a tremendous pace as companies gather even more data per transaction and per interaction with customers and consumers. In areas like health care, security, retail, utilities, manufacturing, and transportation, data is being collected not only through traditional interfaces like computer terminals but also through all sorts of sensors.

So, What Actions to Take to Move Data to the Cloud?

Make sure vendors can meet data security, availability and portability requirements. When evaluating cloud vendors, make sure they are able to meet your requirements for data backup and recovery. If a vendor has completed a third-party audit, that is a good indication that the service adheres to data handling best practices.

Find out what the cloud provider is responsible for and what you are responsible for. Vendors typically have standard service level agreements (SLAs) outlining what they are responsible for in terms of uptime, redundancy, recoverability, etc. Review the SLA carefully to find out what the vendor handles and what you are responsible for.

Consider how software licenses are handled. Be familiar with the provisions of your software application licenses. Some software applications allow you to run a secondary copy at time of event free of charge as part of the license. Others may require a separate license, sometimes at a reduced cost in the event of a disaster.

Know how the cloud environment is maintained. Typically the cloud infrastructure is all handled by the vendor. In a traditional cloud model, the cloud vendor owns and operates the hypervisor down through the hardware stack on behalf of your company, while you control systems from the OS up. If you’re using a replication technology, updates in production will replicate to the cloud. When recovering data, the systems will restore to the latest backup point.

Bottom Line

Whether you are implementing a cloud service for the first time or moving more of your workload into the cloud, having the proper expectations is key. By using the steps above to perform your due diligence and select a vendor that meets your needs, you can help ensure a positive cloud migration experience.

Women in IT – Stereotypes Destroyed!

There are both significant obstacles and emerging opportunities for women who want to work in the information technology industry, whether in a regular post or rising to become chief information technology officer. As well as “an element of sexism” holding back women from these jobs, a real problem has been a misperception around the excitement of working in IT and just how essential it is to organizations running at their best.

Taking the Opportunity

It is in the interests of companies and governments to help women advance in the technology industry, because women offer a fresh perspective on product design, ways of working, risk-taking and many other aspects of business. The teams with the best results are those comprising professionals with different attitudes, methods and backgrounds – those who draw multiple approaches into one unified solution.

Any obstacles can in part be tackled by recognizing women’s strengths, insights and skills to ensure that they are taking active steps in their careers early on, so the IT pipeline remains rich with female candidates.

Flexible Work

As the work is largely on online, women may be able to find a role with flexible office contact hours. This means that they are able to work wherever and whenever they need to – whether that is at home, during transit or in the office. Flexible work options come in all shape and sizes and employee are generally able to negotiate a suitable option that aligns with the companies needs based on the type of work and the requirements of the role. It provides the ability to focus on the outcomes of work without having to be in your workplace to do so.

Engaging Women Interest in IT

As far as the work itself, there is a misconception in pop culture about what for example an information technology engineer actually does. This may be causing some women to shy away from this field. It is not a lonely, solitary existence and most projects will require you to collaborate with others to come up with solutions. Some organizations even encourage or require “pair programming” — where two people share a computer and take turns coding and reviewing a solution. So, now try telling any 12-year-old girl that as a software engineer she could have a job where she works side-by-side with her best friend all day. Then, ask her what she wants to be when she grows up!

Final Thoughts

With a successful mindset and approach to breaking into IT, women also need to be sure that they have the certifications necessary for their field. Just like men, women need to pursue training and experience in their desired field so that they can become more attractive to potential employers who are looking to add to their IT ranks. As more and more women become a part of the tech field, it is clear that the benefits of the female perspective will continued to be bestowed upon companies that make an effort to hire the most qualified candidate for the job, no matter which gender they are.
