1. Explain the issues that are in common with both Amazon and Sony? Issues that are in common with both Amazon and Sony are their reliability and integrity as well as its security. Amazon has just revealed that its Availability Zone in northern Virginia has failed to accommodate customers that were using their services. Sony's hack incident includes its network protection system to be unreliable. Also the security of Amazon's customer's data along with Sony's online users' data is at risk, as well as sensitive information linked to bank accounts. Both Sony and Amazon suffer a setback on their online reputation. Both companies have their servers down which affect a lot of their customers using their services. They both revived worries about the safety of storing and processing data over the Internet. The two crises have also raised questions about the speed and quality of information provided by tech companies when confronted with systems failures. This further links to the data integrity. Amazon users have said that some data may be corrupted or loss resulting from their sites crashing. Sony's users' accounts data may have been altered by unauthorized people. 2. Explain the reasons that cloud computing will continue to grow? Cloud computing will still continue to grow despite its recent incidents because the benefits users receive outweigh the risks that come with cloud computing. The outage suffered by Amazon has been rare. Also, managing one's own network is hardly a guarantee of reliability; it costs a lot of money and is high maintenance. Cloud computing provides another alternative that can save costs for businesses. Also, the recent incidents have proven that managing one's own network is not as reliable as some think considering protection issues and failure/crashes in the network itself. 3. What could have prevented Sony from getting hacked? Sony could have increased its protection system, as well as create random simulations in orde

What were the chinks in the blackout? What are problems with cutting national and international cables? Explain the possible financial impact of blackouts. How can a blackout backfire? march 11 kuni

What were the chinks in the blackout? Many people abroad offered the Egyptians internet though the terrestrial phone system, which was basically a dial-up system. Moreover, Google and Twitter launched a service where users can voicemail their tweets, which is then converted into text, to publish their tweets online. What are problems with cutting national and international cables? It will cost a lot in budget and maybe some damage too, because it is complex and expensive to build and run a kill switch. Explain the possible financial impact of blackouts. The financial, impacts the finance of the blackouts are that money transactions and deposits are affected by the suddenly cut line, which may cause problems to both local individuals as well as large companies that are trying to seal a business deal between each other. An intergovernmental think-tank in paris predicts that the cost of damage in Egypt for its network shutdowns was around $90million. Also, other international countries that are trying to invest in the country that has a blackout are most likely to rethink their decision, and take their investing plans to another more stable country. This affects the country as the whole since they will be losing investors in their country. This would also affect the economy as rates change, the amount of people (tourists) flowing in and out of the country including business groups. How can a blackout backfire? A blackout can backfire its government because it can cause the citizens to view the government's act in a bad way. Cutting of connections will people will stop trusting its government, and would want to overthrow their leader/government. Moreover, This is somewhat a loss for the government. They wouldn't want their citizens to go up against them. Thus, citizens play a major role on how a blackout can backfire. The cutting internet doesn't help at all.

Describe the two issues that came up from the technical problems that interrupted computer services provided by Amazon. Why is the cloud model gaining popularity? List the problems that companies reported. april 28 az

1) Describe the two issues that came up from the technical problems that interrupted computer services provided by Amazon. One of the issues is that Amazon need to reconsider the contracts that cover cloud services such as how much to pay for backup and recovery services, including paying extra for data centers in different locations. The reason for this is because small businesses are less apt to pay for extensive backup and recovery services. The second issue would be many companies are relying too much on remote computers that are beyond their control. So they need to reconsider that also. The technical problem that interrupted computer services provided by Amazon told its customers and users that there may be a reliability problem with Amazon's service in online computing in the cloud. Companies and businesses operation network now revolves a lot around these remote network systems, so this also affects how companies will reconsider their use of exporting their files and data as opposed to keeping them within the company walls. 2) Why is the cloud model gaining popularity? Because owning a data center is high maintenance and therefore expensive. By using the cloud model, companies are avoiding the costs and headaches of running their own data centers. They just simply tap in, over the Web, to computer processing and storage without owning the actual machines or operating software. Businesses can also save their time by outsourcing to the cloud to save having to keep track of running their own data centers. 3) List the problems that companies reported. ( Unable to access data Service interruptions Sites being shut down

summary woo nov 22

This article is about the potential significance of mobile and cloud computing. IBM proposes that there will be more software for Smartphone and tablets than traditional office system in 2015. They say that it is important to be able to adapt new technology, especially cloud computing, computing in which services and storage are provided over the Internet instead of in-house networks, which will eventually play a key determent in all profession in the future. IBM people claim that "A lot of companies we work with today are not only taking advantage of mobile but are putting IT (Information Technology) skills in the hands of all kinds of professionals," and predict that necessary job skills will include ability to handle software applications. Mobile and cloud computing were also ranked the hottest technology career opportunities next year, in a survey. Mobile applications sales are predicted to expand from 6.2 to 30 billion dollars by 2013.

If these systems are developing, the false information will be eliminating. Also it can help authorities evaluate damage more efficiently. Systems using satellite imagery, remote sensing, climate databases and high computing power can predict risk coverage areas by simulating water flows and rain density, with geo-informatics applied to estimate how many households could face damage.

The issue is that the increasing integration of medical devices in hospital networks can increases the risk of being attacked easily, which they hack into the network and steals information. They need to strengthen the security to get against with the possibility of virus attacks which could have a huge damage on delivering data for medication. The Public Health Ministry can play an important role as a regulator in healthcare security, as a same system with the security in the network banking.

However, this isn't a feasible solution since it would cause massive uproar for the users who use the sites on a regular basis, which in this case may be millions of people.
