A Look At The Entirety of Cloud Computing: The Digital Cloud

March 12th, 2015 Comments off

When an Information Technology specialist hears a customer mention eNlight Cloud Hosting, it certainly puts a smile on the IT expert’s face. Obviously, the customer puts a lot of stock into the IT expert’s knowledge and ability to understand their concerns. It is also the responsibility of the Information Technician to discuss the different platforms and help the customer make the right decision. Of course, some specialist will always recommend the Cloud over anything else, regardless of the customer’s specific situation. This is obviously not good for the customer, but it also hurts the credibility of IT experts all around.

The Hype of the Cloud

There is a lot of hype surrounding private cloud computing, since it has the ability to push making decisions at business meetings. An enterprise, which is run by a single individual, might find it easier to do business with a single cloud provider, in order to avoid making a major investment in building their own IT interface. Of course, business people aren’t the only ones, as single people and regular individuals are also compelled by the overall idea of the cloud. Although it can definitely help businesses, individuals can also benefit from this wonderful technology.

The Cloud Concept

When you really break it down, the idea can be explained, as if it were a shuttle bus. Obviously, one single individual would prefer to own the bus and hire each and every one of the crew members, while also planning the bus’s schedule. Although some individuals may be able to support this idea, it is obviously not ideal and will immediately be ridiculed. Much of this has to do with the cheapness of the other options. Wouldn’t it be just as easy to hop on a bus, with a cheaply priced ticket? These big shuttle bus corporations have made the process simpler for the customer, by handling everything on their own, including managing expensive buses and overseeing the activity of their workers. With this possibility, there is really no need for the individual to own the aircraft, since they can travel for cheaper, with a simple ticket.

On the other hand, you could break down cloud orchestration and relate it to the technology and electricity, which is used in our homes each and every day. Obviously, massive power plants and generation centers have a lot of different technologies, buildings and employees to manage at one. However, the customer never has to worry about all of this stuff, since it is already taken care of for them. The entire process is simplified for the customer, who only needs to pay their monthly bill, in order to maintain electricity in their homes.

The History

When you really look at the history of hybrid cloud hosting, you will see that the idea began, by using software as a type of service, which is generally referred to as SaaS. In these specific cases, the service provider will setup their applications and allow the consumer to pay for them on a pay-per-use basis. Although this initially started with the consumer paying to access the individual application, it has now expanded and given the consumer the ability to pay for entire server control. When operating in this manner, it is normally referred to as PaaS.

When it comes down to it, you should really look at the definition of cloud computing, which was offered by the National Institute of Standards and Technology. The NIST suggest that Cloud computing is nothing more than a service, which offers on-demand access to a server. This offers the computer resources to the consumer, while the service provider has to maintain little interaction with either. When it is broken down, the Cloud orchestration model contains five different characteristics, including on-demand service, full network access, pooling of resource, elasticity, and a service, which is measured. On the other hand, the cloud server can be used in three different ways, as a software, platform or infrastructure.

Throughout the years, everyone has benefited from having the ability to create and share documents online, but cloud computing has made the process much more efficient and straight forward. Many are worried about the overall security of this type of infrastructure, but people are able to communicate and collaborate regardless of their geographical differences, which is definitely convenient.

Of course, this is not the only reason that the eNlight Cloud Solutions has become so overwhelmingly popular. It is also the overall cost of the service, which attracts different customers. On the other hand, the universal access of the cloud has also impressed and enticed many individuals to sign up. The ability to easily manage a massive amount of data is certainly enough to draw anyone, who is interested in Internet Technologies.

The Future of The Cloud

With the ability to edit and share documents online through cloud-based applications, the entire process has changed dramatically. In fact, the simple process of storing and sharing documents has taken on a whole new level. While there is some criticism due to security concerns, it is still very effective and allows individuals to share a large amount of data, at once. In fact, these individuals can use cloud apps, as a way to share textual information, documents, video and audio. With the cloud hosting, it is not a major concern, when it comes to the overall size of the documents, which was a problem in the past. Therefore, you will likely see this technology improve and gain popularity in the next few years.

Still, cloud computing has not taken the world, like a storm in the night. It has gone through adaptations and enhancement over the past few years, in order to improve and make it more reliable for users. The service has certainly become much more available and is beginning to make itself more visible in the IT world, which certainly makes it difficult for businesses, corporations and even the individual person to rule it out of their budgets. Of course, it is still likely that the cloud computing service will continue to thrive and grow, as it is updated and enhanced on a regular basis.

Cloud Computing: Facts And Truths That You Should Know

March 9th, 2015 Comments off

cloud-computing-facts-truthsIn recent months, I’ve been poking around various clouds. Along the way, I realized that they were not working the way I expected. Virtual machines are not as interchangeable or as cheap as they seem. Moving to the cloud is not as simple as it should be. In other words, anyone who has thought about the word “cloud” as a synonym for “perfection” or “painless” will be very disappointed.

You cannot say that there is no truth in what the companies claim about cloud, but there is much exaggeration and also plenty of complicated details that are not immediately obvious. In essence, the cloud are not miracle workers. The improvements are incremental, not revolutionary.

To keep our expectations in more realistic level, here’s a list of what we should really expect from the clouds.

1: Uneven Performance of Virtual Machines

Cloud uncomplicated many of the steps related to the purchase of a server. The desire? Press a button, choose your operating system and get the root password. Everything else should be treated by the cloud, which takes care of all computational tasks behind the curtain.

But the benchmarks taught me that virtual machines behave quite differently. Even if you buy a body having the same amount of RAM running the same version of the operating system, you will find surprisingly different performances. There are different chips and hypervisors running underneath it.

2: Many Choices

A great promise from cloud? Rent a Cloud and see what it can do. Your boss may want to invest in buying a rack or collocating the architecture to data center. But spending a few hours in understanding cloud can help in easy decision making.

To rent Cloud under pay per use model is an ideal way for people interested in trying out some features. But with the increasing choice also increases the complexity of analysis and uncertainty about what is really needed.

3: Eternal Instances

After spending some time with the installation of software and settings, many people give up on shut down a virtual machine that costs so little per hour, leaving them in the background waiting for work.

Generally, an audit of the lists of virtual machines takes longer than the cost of leaving them running another month.

I think the cloud companies will make big money with servers that are standing there, waiting for further instructions.

4: Difficulty Dealing with SaaS Pricing

Software as a service is another temptation in the cloud. You do not need to buy the license and install. You send your bits to an API and it does everything for you. But calculate the cost of software as a service involves analyzing several variables.

One of the ways for a company to be aware of the costs is to start the execution of applications in the cloud computing platform, and then calculate the actual costs. But this raises a number of additional issues, such as how to account for the characteristic fluctuating prices of an immature market.

To prove the cloud can be a rather nebulous process, even comparing a private cloud with the traditional IT infrastructure model.

5: Embedded Solutions

When Google announced Google App Engine, it seemed that the device would make the simplest cloud computing. The problem is that the product’s owner needs to use it. This means that you will be tied to it until you can rewrite the software. And who has time to do that?

Not surprisingly, the standard OpenStack is gaining momentum. Everyone is frightened by the possibility of seeing tied to a provider, no matter how good he can be. It takes more flexibility.

6: Security Is Still A Mystery

At first glance, it seems that you completely control your machine. You and only you set the root password. If the OS is secure and patches are installed, that’s OK, right?

All the clouds are far from clear what actually happens under the hypervisor. Cloud providers are far from offering as safe environments like a cage in the center of the room where you can lock your server.

7: The Cost Estimate Is Not Easy

You should buy a faster machine to 7 cents per hour or three slower machines to 2.5 cents per hour? As each vendor has its own way to charge for bandwidth, storage and other resources, expect to spend hours analyzing the use of various sizes of servers. Then put all this data into a spreadsheet to determine the cheapest configuration.

8: Moving Data Is Not Easy

You like the idea of buying computing power per hour? But often the purchase is the smallest part of the work. Getting your data in the cloud can be a substantial task. If you are loaded log files or large data sets, you may be spending too much time in just moving the data you need.

So some suppliers are making it easy to store data locally and then buy computation time when you need it.

9: The Data Is Not Guaranteed As Well

Cloud contracts rarely have disaster recovery. Some vendors are starting to be more clear about its guarantees. Some have terms of service that explain a little better what they cover and do not cover. Others are responding faster and better questions about the physical location of the data, knowing that the answer may be crucial for regulatory compliance or security issues. The geographical distribution is critical for disaster recovery.

One of the most important items in the hiring of public cloud is the agreement of the level of service quality (SLA). Users need better answers from cloud providers on the finer points of management of availability and vulnerability of services before signing contracts. It is important for customers to know not just where your data is stored as who will access them.

10: No One Knows What Laws Apply

It is easy to imagine that the cloud is living in a Shangri-La, away from those pesky laws and rules that complicate the lives of companies. We would all like to believe that cyberspace is a beautiful place, full of harmony and mutual respect, which dispenses lawyers. What is a half-truth, because no one really knows what laws apply.

Not all the laws apply, because the Web extends throughout. As services and solutions are delivered anywhere in the world, this feature of the concept of cloud computing challenges the current legal model, which is based on local laws. As a result, the legal risks are even greater than those of other traditional IT outsourcing contracts, experts in digital right.

Join this borderless world requires more caution in drawing up contracts with service providers. It is important that the contract contains clauses on privacy issues and data availability. Companies should know the risks of hosting information outside of India. In case of a court order, the data confidentiality may be broken, depending on the privacy law and data protection applied by the country where the server is installed.

11: Extras Will Reach

The cloud business seems to be following the same model for collection of hotel companies and airlines. They will do anything to keep the cost of the main service as low as possible, because they know that price is the determining factor for the purchase of the service. But will try to compensate for this cheap price with add-ons.

The problem for most customers is that it is increasingly difficult to predict how many extra services are used. You can estimate the amount of data that will flow between their machines and the server in the cloud? Some cloud companies charge for it. If a programmer uses a data structure such as XML, can quadruple their bandwidth costs.

12: Responsibility For Backup Still Rests on You

It is tempting to buy the marketing hype and think of the cloud as a giant collection of computing resources. When you need to chew numbers, you cast your spell across the ocean and the answers are reborn from the mists.

If you think the cloud will save the responsibility of backing up your data to you, you are mistaken. Underneath it all, the virtual machines are so fragile as the machines on your desk.

In practice, the machines are machines only. If you build a backup plan for your server today, then you should build one for your software in the cloud as well. But It can also fail.
