Benefits of Cloud Computing {4}

by Yeimy F
 According to Cisco, cloud computing services are predicted to increase “12-fold by 2015.” Businesses are considering the use of cloud solution providers such as “Amazon, IBM, Cisco, and Microsoft” to lower cost of ownership. Having an off-site server is considered to be more cost-effective because it reduces the need to invest on costly technology and the number of IT employees needed for server hardware maintenance as well. Moreover, the use of cloud computing services increase workforce productivity because employees are able to access the business applications and data from anywhere there is Internet connectivity. Cloud solution providers are also able to meet the demands of business growth, and provide specialized IT personnel who respond to crisis or failures by providing immediate access to business data files and applications, and offer instant back-up solutions. read more...

AWS Friend or Foe? {2}

by Stephen O
Cloud Computing is a new frontier, in a way it is like the wild west, one that is constantly evolving as new startup companies emerge and take to the field. It is common for one of these start-ups to use Cloud Computing services, because let us face it is cheaper and more efficient for startups to use cloud computing services rather than investing time and money into their own servers. One of the more dominates Cloud Computing Service providers is Amazon with their Amazon Web Services otherwise known as AWS. Right now Amazon and others who use AWS benefit largely because AWS has a strong core of service and has very aggressive when it comes to development. With the way, the Cloud Computing Industry is now there are many open opportunities that startup companies are taking advantage of, but what if AWS starts eyeing the same territory. This is why the Wild West analogy earlier was apt. “I was in a venture capital meeting last week where we were told by one prominent VC that, “Two years ago Amazon was a blessing to startups. Today it is neutral. In two years it may well be a curse.” How so? By building up Amazon Web Services to include many services currently offered by other vendors.” (Rosenberg, 2011) Right now, it holds the lion’s share of the market, because of simple to use API’s and easy to use AMI’s and the whole system is more user friendly than the competitors are. While this maybe the case there are many open areas of Cloud Computing yet open. “As such, there is a huge amount of room for innovation around “cloud” as a whole–storage, network, management–very few existing tools measure up when it comes to the new architecture and programmatic interfaces that we get from cloud in general.” (Rosenberg, 2011) Because there is so much open territory to tackle realistically there is no way that AWS can be everything for everyone, especially if it does not even offer some of these services. It is the opinion of the Author we nothing to fear, it is in the hands of the little guys to stake a claim and protect it against the AWS’ of the cloud. read more...

Cloud Computing the future of small and big businesses. {5}

by Salvador A
With a larger reliance on technology, cloud computing has come to ease the integration between the personnel computer and the internet. In a nutshell cloud computing integrates offline work (such as documents or folders) to an online database. this can remedy the possible event of a hard drive failing or a computer going missing and a person losing all of their important data. Some of the ways of doing this is using Microsoft Office Live. This tool goes ahead and syncs documents or folders that you choose to share with yourself or others that can be edited online or on your personnel computer. Google Docs is another tool out there that does the same thing but has the ability to show edits in real time. I.E if a friend or coworker is using the same document as yourself, you will be able to see the edits that the person is making. The article also goes on to mention two other forms of cloud computing, Using Dropbox to share and sync files and folders and also Calendar sync which can sync your calendars, and display current and future events. read more...

Database Efficiency {1}

by Mike Y

           Cloud computing is becoming increasingly popular. Platforms as a service (PaaS) can rent resources from infrastructure-as-a-service (IaaS) to have level of service required without investing too much or too little. The article concentrates on multitenant databases where a service will try to reduce costs by grouping tenants. This can be achieved by using SmartSLA to efficiently manage data. The research team evaluates SmartSLA by comparing it to the TPC-W benchmark. The tests show that SmartSLA “can provide intelligent service differentiation according to factors such as variable workloads, SLA (service level agreement) levels, resource costs, and deliver improved profit margins.”            Databases must be managed with limited resources to keep costs low while keeping services fast all while maintaining the integrity of the data. This is important today because an increasing amount of information is stored online. Instead of keeping photos locally, many people will upload it to sites such as Facebook or Flickr where it can be shared and accessed from anywhere. If the data is not managed efficiently, the photos can be lost or inaccessible and will lead to an unprofitable business (and enraged customers). In a world where a site can have millions of connections a day, even the slightest increase in efficiency will quickly add up.            There are services that rely on cloud computing such as Google’s services (calendar, documents, photos etc.), Google’s Cr-48 laptop, and OnLive gaming service. As cloud computing increases, so will the amount of data that will have to be transferred. I believe intermittent or slow connectivity and data loss will be eventually be completely unacceptable as technology advances and its use becomes more widespread. In addition to being fast and reliable, databases must also be secure so that private information is not compromised. Another important factor to consider is if the system will scale well with an increasing amount of users. Source: Xiong, P. (2011). Performance prediction for concurrent database workloads.

Worries of Cloud Computing {4}

by Cole O’C
This CNN Money/Tech Fortune article discusses several issues currently present with cloud computing, including cloud outages, security issues, server issues, and general confusion. After Amazon’s cloud outages, which affected both small companies and corporate giants, this monstrously powerful technology has come under more scrutiny. The article argues that, even with outages, cloud computing is still a far safer and more efficient method for most companies. It states that the visibility of cloud outages due to so many companies being affected is a somewhat unpleasant advantage, as an internal IT service could fail without anyone noticing for quite some time. The next topic discussed is cloud security and server separation, mainly focusing on how security issues of one company may affect the others. It uses an example of how Dropbox, a file-syncing startup company, had a programming glitch which enabled users to access accounts without inputting the correct password. While this would be quite disastrous even without cloud computing, it becomes more of a concern when an unsecure server is physically connected to other virtual machines running on the cloud that would be otherwise safe. Lastly, the article mentions the confusing nature of cloud computing, and how the majority of people (stated as 78% according to NPD Group) do not actually understand the concept of cloud computing, while an almost equally-sized majority (76%) uses cloud-based services, such as Hulu and Gmail. read more...

On-Demand Database Service {Comments Off on On-Demand Database Service}

by Alexander V
Summary:

Amazon Web Services started a pay-by-the-hour service for Oracle databases that will compete with Microsoft SQL Azure. Both these services are cloud services. The name of Amazon’s new pay by the hour service is Amazon Relational Database Service (RDS) and it will be available licensing models. One licensing model allows you to use a license that you already own and the other model allows you to buy a license from Amazon. “The new service will likely appeal to Oracle database developers, letting them spin up and down instances as needed and scale to required capacity.” Both models sold by Amazon provide the same features which allow users to do common database administration work such as backup and software patching. RDS is offered in “five database instance classes,” each meeting different levels of needs. The fees for RDS  are $0.11 to $3.40 per hour and “discounts up to 48% are available with one-time, up-front payments for one-year and three-year terms.” read more...

US should embrace the cloud! {1}

by Stephen O
Summary

Imagine in a couple years that cloud computing was twice as big as it was now. There were government standards when it came to cloud privacy and because we had embraced cloud-computing America was the clear leader in cloud computing. We could have that , if  The United States Government and the Industry would work towards spreading cloud computing. The TechAmerica Foundation makes the point if the Industry and the US Government worked together we could all benefit from. The U.S. Government needs to make the first step though.  “The U.S. government can help grow the nation’s cloud computing market by assisting private companies in the development of cloud security standards and by encouraging cloud providers to allow data portability among them, a new tech industry report recommended. The U.S. government can also “lead by example” by stepping up its use of cloud-based services and by revamping its procurement and budget processes to encourage agencies to buy cloud services” (Gross, 2011) read more...

A Walk in the Clouds {2}

by James C
Summary:

Cloud computing has replaced grid computing. The computing paradigm has become an IT resource. The idea of cloud computing has been referred to by many as different concepts. One user characterizes cloud computing as a reservoir of virtualized pc resources. Along with virtualization it also complements grid environments by managing its resources. Another critic describes cloud applications as feeling like desktop programs. Yet another user defines cloud computing as a database of web parts used to construct applications dynamically. Overall cloud computing is not thought of as a new paradigm due to its all-in-one use of current technologies like centralized datacenters, service-oriented software and virtualized computing. The rest of the article goes into explaining further reasons why cloud computing and grid computing are not the same paradigms. It also touches on cloud infrastructures, platforms and applications. read more...

Cloud Computing Brief Analysis {1}

by Dean H
Summary:

Cloud computing has definitely been a hot topic within the recent IT industries. However, due to its nature it is very easy to confuse Cloud computing with other previous introduced technologies. As the matter of fact, many analysts have different definitions toward “Cloud computing.  Some people define it as a updated version of utility computing: virtual servers available over the internet. Others claim that whatever a company consumes outside of the firewall is “in the cloud”. According to the article, Cloud computing can be defined as a way to increase capacity or add capabilities on the fly without investing into new infrastructure, training new staff, or licensing new software. read more...

Cloud Computing and Security Short Comings {3}

by Wendy O

Summary:

The article spoke about high profile companies which were recently scrutinized when they didn’t respond fast enough to data breaches earlier this year. However, what the public doesn’t realize is that if they had actually been storing their data with public cloud providers, it would have taken days just to establish where the data warehouses were located. It could have been significantly worse than what it was. read more...
