Define: AWS Iaas Define and describe: Free redundancy rapid scalability server failover maintainability Explain each lesson and determine whether you agree or not with each one. May 13 az

1) Define: AWS- The Amazon Web Services (AWS) are a collection of remote computing services (also calledweb services) that together make up a cloud computing platform, offered over the Internet byAmazon.com. The most central and well-known of these services are Amazon EC2 and Amazon S3. Iaas - infrastructure-as-a-service; a way to deploy a less reliable server, quickly and without human intervention. 2) Define and describe: Free redundancy- re-deploying your application in another data center or cloud service using on-demand resources instead of having an idle redundant data center. Rapid scalability- Scalability approach that doesn't require access to AMIs that is stored on S3 or EBS. Instead, it uses the on-demand resources. This is when the system can withstand changes in transaction volume without major changes. Server failover- Virtual servers fail more frequently that physical servers, and when they do, there is less ability to recover them. Treat server failover the same way as scalability, just bring up a new server. Maintainability- Use a fully automated deployment and not a server configuration that is created manually to make it maintainability. Since, when a server configuration that is created manually and saved to a "golden image" has numerous problems such as: only the person who built it knows what is there, so if that person is gone, it can be time consuming to re-configure it. On the other hand, a fully automated deployment is not only a maintainable process, it also serves as documentation. 3) Explain each lesson and determine whether you agree or not with each one. Wrong lesson #1 The lesson where the infrastructure of the cloud is either not ready for its time to shine, or never will be. This is the lesson that explains that the infrastructure is still carried out on physical servers, just in remote areas where they are held in the physical data center in large numbers. These physical server

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

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

1. Identify the area of impact the scenario relates to. Business and Employment 2. Identify the main stakeholders to the IT system. Amazon and companies using Amazon's cloud service 3. Identify one ITGS social/ethical concern in the article Reliability 4. Describe ITGS terminology and systems. The hardware used in this situation is the servers used to host information for companies. Amazon's cloud model is used by the connecting to the internet network. The Availability Zones are the zones that according to Amazon, are distinct locations that are engineered to prevent failures in other Availability Zones. Amazon Web Services (AWS) - Amazon's web service that provides companies with infrastructure web service platforms in the cloud. Amazon's Elastic Computer Cloud (EC2) - A web service that provides resizable compute capacity in the cloud, designed to make web-scale computer easier for company developers. Amazon's Elastic Block Store (EBS) service - this service provides block level storage volumes for use with Amazon's EC2 instances. The EBS volumes are off-instance storage that is independent from the life of an instance. http://aws.amazon.com/ 5. If possible, describe a solution to the concern (issue). A solution to the reliability concern is for businesses and companies to filter out what they plan to put on Amazon's cloud services, and what to keep in their private network within their control. Balancing the two would beneficial and can prevent a lot of damage that a failure of a server may do the company as well as its files and data stored in the cloud. Amazon explaining how their cloud service actually works and have it backs up everything should be able to calm down businesses, and regain their trust again once everything is back up and running again.

Describe NoSQL and its purpose. Explain how it is used differently than MySQL. M12 jan30 az

Describe NoSQL and its purpose. NoSQL is a highly scalable and reliable non-relational databases designed to maintain high performance and to be highly cost efficient for workloads of any scale, from the smallest to the largest internet-scale applications. It is also used to build a new kind of database for "unstructured" information that comes spilling off the Internet with each passing second. It is capable of handling large amounts of data du to the fact that they use flash storage rather than traditional spinning disks. These solid-state drives can provide single-digit millisecond response times. Explain how it is used differently than MySQL. MySQL database is a relational database that stores data in neat rows and columns, and it's designed to run on a single machine, while NoSQL database can store data in a more flexible way and is designed to scale across a very large number of machines. "SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle." http://stackoverflow.com/questions/2559411/sql-mysql-vs-nosql-couchdb

What are the problems with doing everything on the cloud? may 19 az

Doing everything on the cloud is efficient in a way that we can work on from anywhere anytime as long as we have internet connection. However, when we don't have good internet connection, there is nothing we can do since everything we have done is stored on the cloud. . Internet data storing plans might also be an obstacle while operating on the cloud because the costs increase as more data is wanted to be stored on the cloud. Moreover, The cloud is not invincible to attacks so your data is not 100% safe. Having a backup saved on a physical hard drive is a must, cause you can't rely too much in the cloud (look what happen to Amazon and Sony).

Why does apple rank low for being green? Which companies are fairly green? Why don't companies want to disclose their energy consumption? Is cloud computing green? Determine if use of IT often reduces environmental impacts or not. april 28 nat

Why does apple rank low for being green? Because of their huge electricity consumption and the increase in their consumption in a new facility, which consumes approximately the same amount of electricity 80,000 US homes. Which companies are fairly green? Yahoo, Google and Amazon. Why don't companies want to disclose their energy consumption? They don't want others to know what they did or what they had to do to reach to the position they are in now. Is cloud computing green? No, it's not green as it already accounts for approximately 2& of the world's electricity consumption, and it is predicted that it will rise. Determine if use of IT often reduces environmental impacts or not. Yes it does, because if something was electronically saved, it can save paper. Moreover, It has been said that there are less carbon emissions produced when music is downloaded of the web, rather than bought in CD stores, because you don't need to use CDs.
