difference between virtualization and grid computing

It's also worth noting that virtualization is possibly on its way to becoming a mainstream approach to managing network resources. Virtualization on the other hand, enables a business or an individual to save on their computing needs and resources by making virtualized version of a physical resource in the same resource. Without even shutting down an image, you can move jobs to new machines without any sort of disruption in performance. Areas of differentiation may be the areas of self-provisioning, granular billing/chargeback and APIs. Virtualization breaks the bond between processing and physical machines, cloud computing enables the use of scalable processing facilities offered by online providers, through virtualization. Now, in 2013, the factors that are increasing an organization's interest in virtualization are speed and agility. Cloud computing makes the system all time accessible. This approach does not require virtualization, but virtualization does lend well to the core concepts of cloud computing. We can virtualize an operating system, that means we can use a Mac, yet running the latest Windows operating system on the Mac, or can have a PC and have three different operating systems running all at the same time. Development was in the early days mostly driven by specific communities requesting amounts of computational power and storage capacities. The main difference between the two concepts is that virtualization refers to the manipulation of software and hardware, while cloud computing is the consequence of this process. A cloud service can be infrastructure for hosting applications or data storage, a development platform, or even an application that you can get on-demand, either off-site at a provider. Machines can be homogenous or heterogenous. Originally, I couldn’t even tell you the meaning of virtualization or cloud computing, let alone what the differences were. Cloud and Virtualization both help to deliver optimized resources, on-demand utilization, flexibility and scalability. CERN was key player concerning in the use of Grid Computing Middleware. Virtualization and Grid computing heading in similar directions. Figure 14 shows that the architecture, developed for dynamic provisioning of computational services in grid. Charalambous Tower An approach more preferable is the user-based dynamic deployment of the Middleware services. Virtualization is a systems admin and data management tool that has many technical uses most of which have nothing to do with the cloud. The second great value of virtualization is that it's great at suspending, resuming and migrating images around an IT environment, in run-time. All the copies are "on" one piece of hardware (the real you). Figure 15 shows the cloud computing adoption model. This could be something like Google docs, where we store the data, or something like Flicker, where photos are stored and can be accessed the items from any device at any time as long as we have an Internet connection. This makes the resource providers’ intervention in the deployment process superfluous and he no longer has to deal with software management and application requirements. I hate burying the lede, so I’m going to give you the briefest answer I can right now: virtualization is the technology, and cloud computing is one of the results of that technology. In other words, users are able to look at the compute power as a centralized resource that they can now allocate to business units on demand, while still maintaining control and operational excellence. These two can be combined together by making a virtual server A in server B and therefore not physically using Server A anymore. Copyright © 2020 IDG Communications, Inc. From an architectural standpoint the question of what should run, where and a clear understanding of the relative cost of processing is essential. As enterprises increasingly leverage virtualization techniques (IDC is reporting more than 60% growth from last year) - that's a question I'm increasingly fielding these days. E.g. But even more importantly, we have seen new technologies evolve over the past decade that are essential to the notion of the cloud.  The key technology is virtualization. Virtualization is often associated with virtual machines and corresponding CPU abstraction. They can easily isolate and partition their systems, so deciding the amount of resources they want to put in the Grid. Generally, virtualization hides the physical characteristics of resources from the resource consumers, which can be end users or applications. First, it allows us to run multiple workloads on a single machine with great isolation between those workloads. Specific VO environments can be prepared following an "install once deploy many" approach, so reducing the operational cost of the infrastructure. It closely aligns with virtualization, but it takes many technologies to be successful. Then resource providers no longer need to commit to a designated Grid Middleware, but can setup middleware’s on demand. As a matter of fact, virtualization exhibits with live and deferred migration of virtual machines even one more feature. Cloud Computing Technology (CCT), is emerging and benefiting a lot to organizations. Companies realized that one way to save money is through virtualization. Even if there are differences and similarities, many in the industry use them interchangeably. Virtualization is not a complete solution to how enterprises manage their resources. Cloud computing is a rapidly evolving discipline and one that will reshape organization charts as fast as it will change data center layouts. Virtualization and cloud computing are two terms that often seem interchangeable if you're not familiar with how either work. Cloud computing can certainly take advantage of virtualization but cloud computing can be accomplished without the use of virtualization. The risk of not knowing the difference between virtualization and cloud computing can be a costly one as hype around these two technologies reaches a steady increase. CloudPassage / July 22, 2011. Virtualization can take many forms aside from servers. Main Focus and Motto. As virtualization and cloud computing become more prevalent, companies are going to need to form new strategic relationships because existing relationships may not have the core competencies needed to drive the fundamental changes that will be needed. The difference between virtualization and cloud computing is simple enough, once you understand both terms. While the two technologies definitely have some things in common, they aren’t identical, and it’s important to know the difference so that you know which one works best for your business. By encapsulating the Grid Middleware into a virtual appliance, resource providers can support the VOs with minimal effort. Multiple operating system instances running on one hardware device are far more economical than a single piece of hardware for every server task. The availability of powerful virtualization solutions gained special interest in managing commercial and academic data centres. It is the technology that has allowed service providers to deliver lower-cost hosting environments to businesses of all sizes today. Together, they are ushering in a new era where companies are granted freedom to run their workspaces without having to conduct non-strategic IT functions such as patches, updates and backups. Instead of delivering a new service in two months, companies are able to do it in two days. Difference between Cloud Computing and Grid Computing Cloud Computing. The third iteration is evolution of cloud computing i.e. For example, one can virtualize a desktop, meaning the desktop is stored virtually in the clouds and can access it from anywhere. Adopting virtualization in smart ways gets us closer to real Grid computing with more flexibility in the type of applications and the resources to use. Middleware’s are deployed in about 250 sites in all European countries and allows access to over 50,000 compute nodes. Thus by using Virtual Machines, Grids can be turned in a very effective resource provisioning platform. But they are implemented in different ways. Rather than having to overprovision on the hardware side to meet peak demands, organizations can use virtualization approaches to get better utilization out of existing (underutilized) hardware. It's also worth noting that virtualization is possibly on its way to becoming a mainstream approach to managing network resources. According to David Martin, Program Director, Internet Standards & Technology, IBM: And not surprisingly, some of the most interesting progress around virtualization is happening in open source. Virtualization breaks the bond between processing and physical machines, cloud computing enables the use of scalable processing facilities offered by online providers, through virtualization. The goal of UNICORE Plus was to develop a grid infrastructure together with a computing portal for engineers and scientists to access supercomputer centres from anywhere on the Internet. Share it! Cloud computing, on the other hand, is access through the Internet to business applications running in a non-local environment. However, virtualization also provides new and powerful features in light of service-based infrastructures or Grids. Sharing of those resources has to be fine grained and highly controlled. These infrastructures are used to provide the various services to the users. Just as virtualization has enabled us to consolidate the servers and do more with less hardware, it also lets us to support more users per piece of hardware and deliver applications and the servers on which they run faster to those users. These kind of scientific virtual appliances (VA) are being packed and distributed in the form of repositories (for example Bioinformatic VA or physics simulation VA). Below table 1 shows the similarities among Cloud Computing and Virtualization. This means that you save money and resources by eliminating server A from the equation. ... such as virtualization, HPC, grid computing and utility computing. Address: Cyprus Headquarters Integrating virtualization technology and all its features into the local resource management system (LRMS) layer is one of the key research areas in Grid Computing. On the other hand, in grid computing, a cluster of computers work together to solve a … (2) Virtualization could be done internally in on-site and the resource involvement except hardware still exists but whereas in Cloud Computing no internal resources will be required. Virtualization vs Cloud Computing: Now that we’ve seen the basic difference between virtualization and cloud computing let us now see, which of these two has more advantages. A given site is able to balance the physical resources allocated to each VO it is supporting. The primary focus in Grid Computing lies in secure resource sharing in terms of access to computers, software and data in a dynamic environment. However, it does provide great capabilities in managing and moving operating systems onto different hardware resources. The deployment of the VMs supporting the worker node is done through the Virtual Wokspace Service (VWS). 32 Stasicratous Street Virtualization. Now, you have cloud computing leveraging virtualization! Example middleware’s are gLite, UNICORE and Globus. By virtualizing the company’s infrastructure, IT admin’s can also create trust zones around information, applications and endpoints that can be adapted to follow workloads through the cloud. private/public cloud, also called a hybrid cloud. Still, there is no direct link to the cloud from pure virtualization. resource virtualization, involving the simulation of combined, fragmented, or simplified resources. Today, we will study 4 types of Cloud Computing Technologies: Virtualization, Service Oriented Architecture (SOA), Grid Computing, and Utility Computing. Copyright © 2005 IDG Communications, Inc. By offloading hardware requirements and utility costs, it can rapidly transform a company’s infrastructure and improve its efficiency by itself. Cloud computing is a set of principles and approaches to deliver compute, network, and storage infrastructure resources, services, platforms, and applications to users on-demand across any network. Server virtualization provides the capability to divide a physical server logically into many virtual servers. The first is a public cloud. Figure 14 explains that how computational services can be deployed virtually in Grid. Virtualization is sometimes seen as the same thing as cloud computing, but it is just a part of it. Cloud was implemented more of a outsourced/hosted model first and then slowly being adopted within the enterprise firewall as an architecture. Where cloud computing and virtualization are similar and differ. Basically, users submit their requests to GridWay (meta-scheduler). Grid computing is a computational model that is It is provided as a pay per use service. The main difference between cloud computing and grid computing is cloud computing banish the need of buying the hardware and software which requires complex configuration and costly maintenance for building and deploying applications instead it delivers it as a service over the internet. A private cloud exists when a company added security with cloud computing, yet they still want their people to have access to their bigger files and bigger databases from any device anywhere. Among other techniques VMs can ensure the correct execution of the application by encapsulating software configurations in a "well-known" environment. For example, virtual desktops alone lower costs by 15%. Key Differences Between Cloud Computing and Virtualization Cloud computing provides an integrated environment of pooled, and automated resources, services which can be accessed on-demand. Differences between Grid and Cloud: 1) Cluster only provides fail over part, if A node breaks while FireFox is running the cluster software will re-start FireFox process on node B. Instead, virtualization allows addressing multiple problems in Grid systems, such as coping with the heterogeneity of Grid resources, the difference in software stacks, and enhanced features in resource management such as more general check pointing or migration models. network based computational model that has the ability to process large volumes of data with the help of a group of networked computers that coordinate to solve a problem together The second form of cloud computing, which is a private cloud, is emerging rapidly. That is virtualization. I’ve spoken with a number of individuals that are a bit confused on the definitions of “virtualization” and “cloud computing”. While virtualization and cloud computing are often considered one and the same, they’re not interchangeable—and the differences between the two have real-world implications for your business. Flat M2 Virtualization vs Cloud Computing. Then GridWay is able to detect the new slot and submit jobs to it through GRAM. Since we implement and support these technologies I had to understand the definitions quickly! Techspirited explains these concepts and points out the similarities and differences between them. However, it does provide great capabilities in managing and moving operating systems (and the full software stack supporting a given application) onto different hardware resources. Cloud computing is inclusive of virtualization and a way to implement it. View. Although virtualization, as a form of technology has existed since the 1960s, only recently with the advent of cloud computing has it become a staple in the vocabulary of those involved in the IT industry. I'll share more thoughts on that tomorrow. From a technical standpoint, virtualization does two things extremely well. It was extended and renamed to UNICORE Plus and reached a mature production state. At the end, this paper describes the similarities and differences between the Grid and Cloud approaches. As Steve Tuecke, CEO of Univa says: Like Grid, virtualization is a trend that's being driven by economics. they should have same type of hardware and operating system. Virtualization is a computing technology that enables a single user to access multiple physical devices. Automated policies can then assess risk and immediately initiate remediation with security problems arise. VMs are a powerful tool for Grid sysadmins also. Although, cloud computing is better utilized if desktop Virtualization is done first, since most Cloud computing requires multiple virtual servers and storage devices to work or what we call multitenancy. It is, however, a fundamental technology that makes cloud computing work. Subscribe to access expert insight on business technology - in an ad-free environment. Like Grid, virtualization is a trend that's being driven by economics. Virtualization is not in of itself a complete solution to how enterprises manage their resources. Cloud Computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. While cloud computing and virtualization rely on similar models and principles, they are intrinsically different. Once the worker node is up and running it registers in the computing element and this information is pushed to the Information Service (MDS). Like it? Cloud Computing. Because corporate IT didn't trust the lack of security of the cloud. Ideally, virtualization has more advantages than Cloud Computing. The gLite Middleware, which is used by the LHC (Large Hadron Collider) Computing Grid High Energy Physics Virtual Organizations (VO), has strong dependencies to Scientific Linux as operating system. The Benefits of Virtualization and Cloud Computing. Cloud computing takes place over the internet. The trend to virtualize everything from servers to processing power to software offerings actually started years ago in the personal sector. So the costs to change grid based applications and to operate the infrastructure are significantly reduced. Rather than having to overprovision on the hardware side to meet peak demands, organizations can use virtualization approaches to get better utilization out of existing (underutilized) hardware. Virtualization on the other hand was started within the boundaries of enterprise firewall and then was utilized in hosted environments. Whereas a grid has many systems in a network and hence multiple people can have ownership. It uses a set of technologies that have been aligned to be highly flexible and provide a wide range of services. Moreover, Foster proposed a three point checklist which characterizes a Grid more in detail: delivery of nontrivial qualities of service; usage of standard, open, general-purpose protocols and interfaces e.g. Cloud computing is essentially the ability to acquire or deliver a resource on demand, configured however the users chooses and paid for according to consumption.  From a supplier's perspective, including both internal IT groups and service providers, it means being able to deliver and manage resource pools and applications in a multi-tenancy environment, to deliver the user an on-demand, pay-per-use service. However cloud can be implemented without virtualization as well. Cloud Computing and Virtualization are two different technologies, these technologies will work independently. Virtualization received a big push in 2009 and 2010 because of the recession, which prompted many companies to cut their IT budget. This is achieved by balancing the number of virtual worker nodes allocated to each VO. Leveraging virtualization to better serve users give organization the obvious lower TCO, but also allows for accountability of usage, simplifies and meets the needs of on-demand infrastructure requests and allows ability to serve, control and manage SLAs. In the past, it was common for individuals within major organizations to use virtualized services or cloud computing when at home, but at work they weren't using those services at all. Companies are now beginning to establish private clouds. Cloud computing adaptation model consists of layers such as i) hyper cloud where dynamic sharing and self service application provisioning are done, ii) cloud foundations where cloud environments, deployments ways, load balancing are done, iii) cloud exploitation where foundations for scalable application architecture are carried out, iv) cloud experimentations where architectures experimented and v) virtualization where infrastructure and applications are virtualized. Nicosia 1065 The role of virtualization in grid computing is explained. Simply put, virtualization can make one resource act like many, while cloud computing lets different users access a single pool of resources. It is shown how virtualization can be used to develop a grid site. They are not sure if the terms mean the same thing or how they may be linked. Virtualization and cloud computing go hand-in-hand and virtualizing servers is just the tip of the iceberg. Although the two … Cloud computing, which refers to companies using remote servers that can store data and allow users to access information from anywhere, takes three different evolutionary forms. The system leverages virtualization technologies to provide flexible support for different VOs. Virtualization is used in many different contexts, which can be grouped into two main types: platform virtualization, involving the simulation of whole computers and. By providing this hardware level abstraction and strong isolation between multiple host operating systems, if one workload crashes, the other can continue to run unobstructed. Virtualization helps in providing cloud better security. The system deploys on-the-fly VO-specific (familiar) worker nodes to execute their applications. Grid and cluster computing are the two paradigms that leverage the power of the network to solve complex computing problems. In addition to some amazing cost savings and goodness for the environment, virtualization's ability to separate the OS and application from the hardware give it ideal properties to best deliver these on-demand cloud services. That's the power of virtualization. Because virtualization consolidates multiple physical components so that they can be managed in one place, it mitigates the complexity of monitoring these components across both internal and external infrastructure.

Getting gLite to work with other operating systems is a complex task. This technology allows enterprises to use a single piece of physical hardware, to perform the work of many. Practically, cloud computing is a concept created from one product, virtualization. Private cloud computing does not center on virtualization or any one technology. Difference Between Cloud Computing and Virtualization (1) Virtualization is a Technique but Cloud Computing is a Concept using Virtualization techniques. Difference Between Cloud Computing vs Virtualization. Like the gLite Middleware, also other Grid Middleware’s can be packaged as virtual appliances. The majority of current applications are in the area of CPU virtualization, storage virtualization and network virtualization. Cloud computing is used to define a new class of computing that is based on the network technology. Summary: Difference Between Virtualization and Cloud Computing is that virtualization is the practice of sharing or pooling computing resources, such as servers and storage devices. Cloud computing uses a client-server architecture to deliver computing resources such as servers, storage, databases, and software over the cloud (Internet) with pay-as-you-go pricing.. In short, virtualization enables organizations to have greater control and better visibility into their infrastructure, simplifying security management for the cloud. In terms of implementing virtualization and cloud computing options, organizations are now starting to move quickly. How do virtualization and Grid relate to one another? Cyprus, Copyright © 2020 | Powered by Brandconn Digital. From an architectural standpoint the question of what should run, where and a clear understanding of the relative cost of processing is essential. First of all let’s see the short version of my answer on differences between the two concepts – “Virtualization is a technology, whereas cloud computing is a business model/approach.” So now let’s step through the differences in detail, They have closely aligned their products with tools and complementary technologies that promote the adoption of private cloud computing. Virtualization is one of the technologies that makes cloud computing possible. Depending on the virtualization platform this can be done on-the-fly or by suspending and resuming. Virtualization is the establishment of cloud computing. Computer Network Computer Engineering MCA. Hence, virtualization has played and will continue to play a huge role in cloud computing. The architecture consists of i) Physical machines, ii) Physical worker nodes, iii) Infrastructure manager, iv) GridWay, v) Virtual Workspace Service (VWS) and vi) Grid middleware components such as Monitoring and Discovery of Services (MDS), Grid Resource Allocation Manager (GRAM) and GridFTP. Cloud computing is as much a methodology as it is a technology. For example, through virtualization, IT teams can standardize VM images and create back up versions of critical VMs more frequently than in the past, simplifying recovery. For example server A is only utilized by 30% most of the time and server B is utilized only by 50%. Virtualization and cloud computing are also so closely connected because the major hypervisor vendors, VMware, Microsoft and Citrix Systems are putting a lot of emphasis on the cloud. Difference between Cluster and Grid Computing: Cluster Computing Grid Computing; Nodes must be homogenous i.e.
