The Benefits of Mobile Applications for Consumers Using the Cloud
With the development of cloud computing, data has become mobile, transferable, and instantly accessible. Mobile technology had made almost every aspect of our lives portable. Thanks to laptops, notebook computers, mobile and smart phones, GPS devices and wireless debit/credit payment terminals there are a variety of ways to access this data on the go. This technology offers individuals more flexible working practices, more flexible payment options for customers, allows businesses a way to provide better customer service, it increases productivity, and supports decision making. Customers can now log into a payment center via their cell phone or computer and pay bills without ever having to leave the comfort of their own homes should they choose to do so. They can review transactions, read emails, share photos, update their social networking relationships, and check in with doctors while refilling prescriptions all from the palm of their hand. The possibilities are limitless. Executives can still be actively involved with the day to day business activity while traveling whether it be from a hotel room or an airport. The freedom the cloud has given to working mothers is also a huge benefit. Some even believe that cloud computing offers advantages to nearly every entity in the ecosystem. Enterprises gain three solid benefits from using the cloud.
The platform that fits all three of these questions is the best one to start with. Today it is expected that the same app or a variation of the app be available for several different platforms.

High Availability and Mobile Users
Today mobile technology users depend on their devices for fast, reliable, easy access to email and mobile business applications. Any downtime can adversely affect businesses with respect to customer service, productivity, sales and revenues. Businesses and individuals alike have become expectant of 24/7 application delivery. Service failures, downtime, and bad weather are no longer acceptable excuses for down time. Planned outages are easily managed but the catastrophic affects of unplanned downtime can bring about serious consequences. (Technical Whitepaper, 2009) Even a few minutes of application downtime can cost big financial losses, erode client confidence damage brand image, and present public relations problems. , 2007)
Designing for availability is about anticipating, detecting, and automatically resolving hardware or software failures before they result in service errors, event faults, or data corruption — thereby minimizing downtime. The technology part of the solution requires multiple routes to application services and data. The operational part of the solution is to use only tested, proven processes (both automated and people-based) to support the application throughout its entire lifecycle. (Microsoft, 2012)
Clustering is one of the most preferred methods for trying to provide continuous availability for applications and servers. This is done with multiple computers that are physically networked together and logically connected using cluster software. This software allows two or more independent servers to work as a single system. If a failure occurs, the workload is moved to another server, current client processes are switched over and the failed application restarted. This all happens automatically and it gives the appearance of no downtime. There might be a slight delay but the service will be completed. A few benefits of clustering are reduction of unplanned downtime, reduction of planned downtime, continuous health monitoring and it is compatible with industry standard hardware.
Another method is called Network Load Balancing. This is similar to Clustering except the Web traffic is evenly distributed over a number of servers. This method automatically detects server failures and redirects client traffic to the other servers within seconds providing uninterrupted, unbroken client service. Some of the benefits of this method are continuous application service and incremental server additions.
Replication is another method that mirrors data to a remote storage system so that if the primary storage system becomes unavailable, the data can be retrieved and accessed through the remote subsystem. There are other methods available to reduce downtime as well: using RAID for data stores, reducing planned downtime by using rolling upgrades, queuing, and using a Distributed File System. With many methods to assist us with providing high availability, one thing is for certain; it is expected. (Microsoft, 2012)
Mobile Computing and Social Networking Due Week 7 and worth 75 points Mobile computing has dramatically changed how information is accessed and shared. Wireless networking has been an enabler of mobile computing. One profession that mobile computing has had a big impact on is health care management. Patients are now able to monitor their vital signs such as blood pressure, glucose levels, etc. without having to periodically visit a doctor’s office or hospital. There are devices such as the Withings Blood Pressure Monitor that works with an iPhone, iPod Touch, or iPad to record, track, and graph a patient’s blood pressure. There are other devices that can measure blood glucose levels, oxygen levels, heart rate, etc. and use an iPhone to send the results to a clinical server. Doctors and caregivers are then able to access the data on the clinical server. According to the American College of Gastroenterology, social networking sites like Facebook, Twitter, and YouTube are used as powerful platforms to deliver and receive health care information. Patients and caregivers are increasingly going online to connect and share experiences with others with similar medical issues or concerns Patients are able to take advantage of social networks to do more than just share pictures and tweets. Write a four to five (4-5) page paper in which you: Compare and contrast monitoring of patient vital signs using mobile computing technology to in-patient visits to the doctor’s office or hospital. Analyze the advantages and disadvantages of using mobile computing technology to monitor patients. Assess the security concerns with regard to the transmission of personal medical information over wireless networks. Assess the use of social networking for group support for patients with similar medical concerns. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources. Your assignment must follow these formatting requirements: Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions. Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
