You have developed a new web application in the US-West-2 Region that requires six Amazon Elastic Compute Cloud (EC2) instances to be running at all times. For example, you can run macOS on a virtual machine instead of iMac computers. Today, AWS is the largest cloud provider that uses Xen as its preferred hypervisor. Companies use hypervisors to consolidate multiple computers that perform different functions into a single server. EC2 users do not own the physical servers; AWS provides virtual servers. 3. Because EC2 instance is running on Xen and EC2 is a paid service, Amazon has the right to alter this underlying hypervisor's license and any other proprietary rights with no notice to the EC2 customers. Both hypervisors and containers provide virtualization but at a different software layer. At its core, the hypervisor is the host or operating system. You can customize CPU, storage, memory, and networking resources when you set up an EC2 instance. Amazon EC2 dedicates some resources of the host computer, such as CPU, memory, and instance IT teams can allocate memory, networking, processing, and storage resources across multiple servers as needed. e. You must use ECS to manage running Docker containers in AWS. You definitely can install Kubernetes, yourself. This has resulted in tight coupling of VMs to their underlying hardware hindering live migration of VMs to different providers. AWS has completely re-imagined our virtualization infrastructure. Deploy Hyper-V server for Nested Virtualization on AWS. LXC (lex-see) is a program which creates and administers containers on a local system. d. No. Like software appliances, virtual appliances are intended to eliminate the installation, configuration Another critical feature of hypervisor is that it isolates virtual machines from each other and the host computer. Multiple users bid for an EC2 Instance. It is a small software layer that enables multiple operating systems to run alongside each other, sharing the same physical computing resources. So users only pay for the usage of the servers, saving them the cost (and associated ongoing maintenance) of investing in physical hardware. an instance and use your own benchmark application. ELB ELB, also known as Elastic Load Balancing, automatically assigns received application traffic to several Amazon EC2 instances.In order to get higher fault tolerance in users applications, ELB offers the load balancing capacity needed.
