Worksheet 2 AWS EC2

AWS EC2

Amazon EC2 provides the broadest and deepest instance choice to match your workload’s needs.
General purpose, compute optimized, memory optimized, storage optimized, and accelerated computing instance types are available that provide the optimal compute, memory, storage, and networking balance for your workloads.
Processors from Intel, AMD, NVIDIA and AWS power these instance types and provide additional performance and cost optimizations.
Local storage and enhanced networking options available with instance types further help optimize performance for workloads that are disk or network I/O bound.
Many instance types also offer bare metal instances that provide your applications with direct access to the processor and memory of the underlying server for running in non-virtualized environments or for applications where you want to use your own hypervisor.

Features

Functionality – EC2 provides its users a true virtual computing platform, where they can use various operations and even launch another EC2 instance from this virtually created environment. This will increase the security of the virtual devices. Not only creating but also EC2 allows us to customize our environment as per our requirements, at any point of time during the life span of the virtual machine. Amazon EC2 itself comes with a set of default AMI(Amazon Machine Image) options supporting various operating systems along with some pre-configured resources like RAM, ROM, storage, etc. Besides these AMI options, we can also create an AMI curated with the combination of default and user-defined configurations. And for future purposes, we can store this user-defined AMI, so that next time, the user won’t have to re-configure a new AMI from scratch. Rather than this whole process, the user can simply use the older reference while creating a new EC2 machine.

Operating Systems – Amazon EC2 includes a wide range of operating systems to choose from while selecting your AMI. Not only these selected options, but users are also even given the privileges to upload their own operating systems and opt for that while selecting AMI during launching an EC2 instance. Currently, AWS has the following most preferred set of operating systems available on the EC2 console.

Amazon Linux
Windows Server
Ubuntu Server
SUSE Linux
Red Hat Linux

Software – Amazon is single-handedly ruling the cloud computing market, because of the variety of options available on EC2 for its users. It allows its users to choose from various software present to run on their EC2 machines. This whole service is allocated to AWS Marketplace on the AWS platform. Numerous software like SAP, LAMP and Drupal, etc are available on AWS to use.

Scalability and Reliability – EC2 provides us the facility to scale up or scale down as per the needs. All dynamic scenarios can be easily tackled by EC2 with the help of this feature. And because of the flexibility of volumes and snapshots, it is highly reliable for its users. Due to the scalable nature of the machine, many organizations like Flipkart, Amazon rely on these days whenever humongous traffic occurs on their portals.

Assignment Class Activity - Storage Virtualization

What is storage visualization ? Storage virtualization in Cloud Computing is nothing but the sharing of physical storage into multiple storage devices which further appears to be a single storage device. It can be also called as a group of an available storage device which simply manages from a central console. This virtualization provides numerous benefits such as easy backup, achieving, and recovery of the data. Benefits of storage virtualization It is highly scalable. It allows easy addition and deletion of storage without affecting any application. Easy data migration. Easy storage management. Diagram of Storage virtualization Types of storage virtualization Block level File level Block level storage virtualization is implemented in “ SAN (storage area network) ” and it provides a translation layer in the SAN, between the hosts and the storage arrays. In this type of storage virtualization, servers are redirected to virtualized LUNs instead of LUN’s on the individu...
