Data Center, Hypervisor, And Container-Based Virtualization Technologies

Applications of all kinds are critical to the daily operations of enterprises all over the world. While hypervisor virtualization technology has become the standard for managing applications, software components, containers enable IT professionals to install, run, maintain, and upgrade applications and their surrounding environments quickly, consistently, and more efficiently than their hypervisor counterparts. This is making Containers a popular topic for many IT professionals, and is increasing traction in the enterprise.

Data Center: The data cetane is the facility which is for the housing computer systems and the other associated factors like the telecommunication and the storage systems. This includes the redundancy of the backup of the power supplies and handle the communication connections as well. There are different aspects for business continuity where the company relies on information system for running their operations.

Hypervisor based Server Virtualization Technology: It focus on the functions which leads to work on operating systems and the different applications of computer hardware. The abstraction allows that the host machine is for independent operations with virtual machine as guests that allow VM to share system computing resource like memory space. 

Container Based Virtualization: They mainly focus on virtual isolation with reliability on deploying and running the applications. The working is based on accessing the shared operating systems without virtual machines. The container technology has partitioning roots with Docker system like LXC (Linux Containers)

Task 1: Discussion of following Aspects 

Purpose

Data Center: The data center works on handling the operations with proper management of carrier telecommunication network. It provides the hosted applications and provide services to customers, where there are combinations defined for similar data center applications. The operations are required to balance facility and housed equipment to establish a better standardization and modularity.

Hypervisor based Server Virtualization Technology: They are used for working on physical host system with improving the underlying software utilization [1]. Here, the servers are only the host operating systems where the virtualization is based on allowing different VM instances.

Container Based Virtualization

The purpose of it to focus on the applications with approach where the layer runs on application for operating systems. They are for executing the data centers with the virtual machines in cloud. The network topology is based on handling the different challenges and working towards transforming the creation of problem with software environment developers.

Working

Data Center: The working is based on handling the use of organization, processing, store and disseminating of the larger amount of data. The services are based on the focal points which includes air conditioning with virtual data center access that makes it for different organizations and personnel. The client and leasing organizations are working on consolidation and colocation with modern business through use of two or more data center installation with different locations [5].

Hypervisor based Server Virtualization Technology: VM working is based on the running of the machines which are presenting the guest operating system for properly managing the operating system guests.

Container Based Virtualization

They are holding the components which are important for running the desired software. The components generally include the files where the environmental variables and the dependencies are determined through hosting OS and the constrains are for accessing to the physical resources like CPU and storage. The container image files are worked upon through docker images with multiple layers that works on container execution code.

Scalability

Data Center

The classification of the system is through certified Uptime Institute etc. It includes virtual ranking where the data center tier ranking includes requirements and criteria with infrastructure, levels of redundancy and uptime. It includes 4 tiers which are:

99. Tier 1: They are simple for lower levels of redundancy with larger data centers set with backup cooling system or generator. The uptime is 99.9671%
100. Tier 2: They are for the redundancy and involves backup or the cooling of system. They are 99.9741%
101. Tier 3: The are for meeting the requirements with high redundancy and uptime. It is at 99.982% [2]
102. Tier 4: This is for the involvement of great infrastructure with high redundancy and uptime at 99.995%.

The example for this is Rack bank which is in central India in SEZ

Hypervisor based Server Virtualization Technology

Type 1: Native or baremetal Hypervisors: The hypervisors run directly on hardware with managing guest operating systems. IBM development includes testing software SIMMON operating system.

Type 2: Hosted hypervisors: They are for handling conventional operations with computer programs. The guest operating systems generally runs on processing on hosts with abstract guest operating coming from the operating systems. The example is VMWare workstations, player.

Container Based Virtualization

They work on handling the Open Container Initiatives which are for the layers of file system and configurations. The specifications are for the runtime and the specification of image. This is based on handling the information that is needed to perform and launch the applications with the services in OCI containers [6]. The container engines executes the images with use of container scheduler with management of deployments. They have a higher portability with dependences that are important for the execution of code.

Features and Weaknesses

Data Center

The data architecture and requirements are for the cloud service providers where organization Amazon EC2 satisfied the facilities, with infrastructure, and security requirements with focus on the forms of private data center. The built-in for the Pentagon with dedicated to securing the classified data. The limitations are about the security and the metal structures that leads to problems.

Apple works on the data center network with putting companies complete command and control with infrastructure support through strategic applications [3]. The reality is about how the companies are working with data center capacity in-house and the outsourcing with considering about the corporate data center requirements that are going into facilities from the wholesale data. The problem is about the static discharge problems to damage components. Some of the famous data center solutions are Cisco, Datacom etc. 

Container Based Virtualization

Hypervisor based Server Virtualization Technology

The features of VM is that it works on multiple user applications to run and allow the multiple operating systems to run virtual machine context [7]. The robust time sharing, and mainframe computers work with increased robustness and security.

The issues of security where containers are less secured than hypervisors. VM tends to isolate applications & OS systems, where applications get compromised with attacking single OS in the container.

Container Based Virtualization

The example of this is Amazon web services and then Dell server for the production.

In AWS, the features are that they work with properly handling the virtuated architecture through abstraction and then substituting the physical machine to it. The applications work with Dockers which are for encapsulation of the files, dependencies and the libraries which works on running on the system OS. There are issues related to the performance problems when connected to the resource contention[ 4].

In Dell: The features of container are for enhancing the flexibility and allowing to move the software applications to distribute the host operating system types. It includes the maximized efficiency with proper storage, CPU and memory. The problems are related to the isolation of the host operations where container tends to share the system with security threats that lead to harming the complete system as well.

Socio-Technical aspects

Data Center

The data center is for working with minimizing the chances of security breach and then working towards the better telecommunication networking which is for installation of the devices in the spaces.

Hypervisor based Server Virtualization Technology

The socio-technical aspects are related to the security standards where hypervisors are then working on properly detecting of malware and intercepting other operations of OS without any anti-malware software.

Container Based Virtualization

There are multiple containers for running on single OS, where the probability is to end up the occurrences with higher single point failures. Hence, there are developers for singing the containers in a digital format [7].

Conclusion

Data Center: The data centers take hold of the information with use of resources like CPU memory, disk I/O and the network which leads to form a collection of processes as well. There are collection of processes that works with using the server hardware and operating systems, with working on handling the share of kernel resources with fully managing resources and security.

Hypervisor based Server Virtualization Technology

The instances are defined through sharing virtualized hardware resources like Linux, OS and Windows. The operating system level includes the operating system with hyper used stronger variants [8].

Container Based Virtualization

The container-based virtualization is important for the technology developers to work with different workloads and make the information technology atmosphere flexible and scalable. It includes the adopting through larger enterprises with small and medium business where the precise virtual machines are best.
