Tips in using MySQL in AWS {Comments Off on Tips in using MySQL in AWS}

by Jim J
The next generation of storing data is in cloud computing. Amazon cloud offers these kinds of services few things can be done to overcome most of the performance issues. Amazon uses elastic book storage (EBS) which appropriates network resources to its users and which has performance that varies depending on availability; this is their greatest weakness. Ways to mitigate this is taking advantage of the cache in browsers, objects, queries, and data. Many MySQL settings can be tuned for performance benefits such as increasing buffer sizes and even things like using a high-performance file system like XFS. In addition to performance benefits, DBA’s need to ensure data redundancy taking use of multiple data centers spread across the globe so as to have options for when a server goes down; recovery is equally important where DBA’s need to automate getting their servers back up and running. Some companies like Netflix even run programs that randomly take out servers during the day so as to test out their ability to stay on-line. read more...

Cloud Computing, a Competitive Advantage {2}

by Abel R
Cloud computing can give any business the capability to access applications and data from anywhere in the world on demand. Another attractive benefit is the fact that cloud computing is a service and the user (business) is not responsible for costs associated from buying, upgrading, or maintaining any parts. Thus a small business can pay for the service on demand, this is significant because small businesses who have limited resources can now use cloud computing to create a competitive advantage over its competitors. read more...

LG introduces a Beta Cloud Streaming Via LG Cloud {3}

by David A
On Monday April 30th, LG reveals a new service called the LG Cloud.  It will allow users with LG devices to access and stream their data from anywhere, currently available in the US and Korea as a Beta version. LG will offer 5GB of free storage for those without an LG device and 50GB of free storage for those that do.  Compared to other cloud services LG believes that their service will perform a lot better because of their streaming feature.  Since the files don’t have to download first, the lag time will be decreased dramatically.  LG uses a technology called the Real-Time Streaming Transcoding which means that the conversion happens on the server in real-time, and not on the device.  Everything will be done seamlessly and in the background, so there will be no need to install codecs or converters on the devices.  LG will offer other levels or tiers of service and pricing as they are released to the world.  LG believes that their service will be a one stop shop for all their cloud sharing needs.  The customers will no longer need to have a separate cloud provider for their music, video, photos and office files.  LG Cloud will work with Android devices 2.2 and higher, PCs running Windows XP and Windows 7, and on LG TVs running Netcast 2.0 or higher. read more...

Google Drive, Using Your Files For Advertisement {1}

by Robert T
In Casey Johnston’s article featured on Wired’s CloudLine, Johnston writes how Google’s highly anticipated cloud service, Google Drive, could potentially use your stored data for their advertisement. According to Google Drive’s terms of services, Google Drive is able to use whatever you as a user lists as “public.” For some time now, people that use Google’s services have been weary about the methods Google uses to index user searches.
“Several publishing outfits raised the alarm about a clause in Google’s terms of service that states Google reserves the right to ‘use, host, store, reproduce, modify, create derivative works (such as those resulting from translations, adaptations or other changes we make so that your content works better with our Services), communicate, publish, publicly perform, publicly display and distribute’ content uploaded to their services.” From what Johnston’s article is saying, Google doesn’t necessarily own the content you upload to the cloud, but unless you take the proper measures to keep your files listed as ‘private’ you may see a picture of you and your family used for advertisement somewhere around the internet. read more...

Google Drive : Privacy {5}

by Abel R
Google drive is a place where you can upload almost anything you want and  access it anywhere at anytime. If that is not enticing enough, Google offers 5gb of free data storage for free!!  But, what many don’t know or never read are Google’s unified terms which covers all its products. Taken from Google: “When you upload or otherwise submit content to our Services, you give Google (and those we work with) a worldwide license to use, host, store, reproduce, modify, create derivative works (such as those resulting from translations, adaptations, or other changes that we make so that your content works better with our Services), communicate, publish, publicly perform, publicly display, and distribute such content.” After reading this, you get the sense that your data is basically Google’s and it can do as it wishes with it. read more...

Over Indulgence with Cloud {2}

by CyberChic
As Alexander Haislip, writer for Tech Crunch, starts his informative article “Sins of Cloud,” he provides a great introduction comparing Cloud to the Creation of the World and that it was intended for good, but cautions users to watch out for pit falls which can add costs.  The first is use only what you need and turn it off when finished. Giving the example that “instances of machines often run idle between 15% and 40% of the time. “  Next is adding services like updating patches.  At $100 per month and $0.12 hour it can add up and suggests doing it in house to save money.    He ended stating that sometimes you need to leave the cloud if it’s a better fit for your company.  read more...

Amazon Web Services Leading With DynamoDB {1}

by Edwin T
Amazon web services has delivered a new technology know as DynamoDB that is a fully managed NoSQL database service.  Current database layers have trouble keeping up with the demand of modern applications. As more requests come in, the database slows down and reduces overall performance.  Increasing the amount of hardware to try and scale current databases is very expensive and requires the expertise of engineers to make it work.  This approach can only be done for so long.  Eventually all the hardware and physical storage devices will become a burden when it’s time to update or patch anything.  DynamoDB is not software, it is a service that takes care of this problem.  The administrator can simply dial in or increase the amount of requests the database needs to handle per second; the service will distribute the data through the necessary hardware to avoid down time.  The requests are very fast because the data is stored in solid state drives.  In addition, DynamoDB is very reliable and secure, it automatically replicates data in whats known as Amazon availability zones in case of hardware failure.  “Amazon DynamoDB is already in use by many teams and products within Amazon, including the Amazon.com advertising platform, Amazon cloud Drive, IMDb and Kindle.” read more...

LogMeIn vs. Dropbox {4}

by Ronny W
Dropbox have been the leader of cloud storage for a good amount of time. LogMeIn announced their beta ‘Cubby’ service to compete with Dropbox. Cubby offers more data and they are “a P2P data sync feature and the promise of user-managed encryption keys.” (Dunn, 2012) With P2P sync service, it means their are no data limit, but computers needs to be to do it. Cubby cloud save and sync that is pre-defined, so it works kind of like a backup service. Files that are saved have visual notification that tells the user what is happening. Users can also sync their files onto their smart devices. Cubby is easy to set up and during beta they did not experience any crashes or freezes. Cubby beta offers data encryption keys assigned by the user. They most of the data will be hosted on US for now. They have data where there are laws protecting these data. Pricing is not announced, but they are going to be up against Google, Microsoft, and other cloud services in the near future.
During class, a lot of the questions have been raised up in where the data is being stored and how secure it is. LogMeIn announced that their data will be stored in US for now. This can assure that if other country were to have a disaster, people who have their data saved in Cubby will be safe. They don’t need to worry if their data will be gone due to natural disaster or other unknown governmental factors. Cubby allow users to encrypt their data with their own encryption key, so it is harder for other people to gain access to the data even if it was hacked.
Cubby seems like a reliable cloud computing service in this article. They allow more storage space for free and they have not experience any crashes or freezes during testing. It can prove to users that they are stable and reliable. They answered a lot of the questions  people have about cloud services. They provide stability and security which have been the biggest issue for businesses to implement their system into cloud. Cubby might just be the new guy that everyone dislike in the near future.

Virtual Microsoft Office for iPad {1}

by Robert T
In Jon Brodkin’s article “Virtual Microsoft Office for iPad: Blurry But Free, Legal,” Brodkin explains how the application market for tablets are releasing software to compete for full office suites very similar to Microsoft Office. Microsoft has yet to publish the Microsoft Office suite to tablets and as a direct result, many independent  producers have been trying to release some of their own applications that would be compatible with Microsoft’s standards. According to Brodkin ,”OnLive Desktop, the service that stirred up controversy by providing Windows and Office on the iPad and Android tablets without being properly licensed by Microsoft, has now gone legitimate  with new code on the backend. But there are already reports that the service’s usability is suffering as a result.” On top of that Brodkin mentions another program known now as CloudOn. The application is far from the solution many people are looking for, but it’s stable, it works, and best of all – its free. However, it has been announced that the currently free application will later release a paid upgrade that will include ,”more functionality, such as macros, commenting and annotations.” CloudOn is currently available for iPads but is soon to be released to the Android market. The application is built so that it operates using a cloud hosted by Microsoft Office copy of PowerPoint, Word,and Excel. read more...

Disaster Recovery combine with the cloud {1}

by Robert Q
The article by Jeff Vance, “How the cloud democratizes and complicates disaster recovery”, goes over what the cloud can do to help businesses with their disaster recovery plan. The author points out that most businesses don’t have a DR plan in place or most businesses would back up the most important data to tape and shuffle the tape off to secure location or would even hope and cross their fingers that nothing will happen. The author believes that businesses are not taking advantage of the cloud and what it can do to help a business with their DR plan, however the author notes that businesses should not take a laissez-faire approach to using the cloud for their DR plan because there are some negative parts that the businesses need to account for. The author said that using the cloud as a DR plan is only scratching the surface of DR plans, organizations need to adapt their DR plans with the cloud and other plans. read more...
