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

- this technology is that the normal video communicate that by the internet to connect to each other. For example, Skype, or Facetime etc. Advantages and disadvantages. - The advantage is that when children want to learn some music but parents don't have time to drive them to the music school, they could have lessons at home which is easy to do. - The disadvantage is that we need many thing to learn via computer, for example, webcam or video camera, good quality speaker, good quality microphone etc.

Mobile device security requires persistence, diligence and, of course, common sense. In recent months, iOS and Android security have been hot topics of discussion in response to major breaches that impacted both operating systems this summer. their data breaches a legitimate but avoidable threat. In addition, software updates a necessity
