difference between virtualization and grid computing

The availability of powerful virtualization solutions gained special interest in managing commercial and academic data centres. Nicosia 1065 This is achieved by balancing the number of virtual worker nodes allocated to each VO. It's also worth noting that virtualization is possibly on its way to becoming a mainstream approach to managing network resources. Among other techniques VMs can ensure the correct execution of the application by encapsulating software configurations in a "well-known" environment. Virtualization helps in providing cloud better security. Virtualization enables us to do things faster, thus making the company more agile. 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. Virtualization is a computing technology that enables a single user to access multiple physical devices. 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. Depending on the virtualization platform this can be done on-the-fly or by suspending and resuming. Basically, users submit their requests to GridWay (meta-scheduler). 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. Figure 14 explains that how computational services can be deployed virtually in Grid. Virtualization is a systems admin and data management tool that has many technical uses most of which have nothing to do with the cloud. 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. Hence, virtualization has played and will continue to play a huge role in cloud computing. Cloud computing, on the other hand, is access through the Internet to business applications running in a non-local environment. The first is a public cloud. Cloud Computing. Typically an LRMS supports job suspension and checkpointing out of the box, whereas virtualization offers the same features not for jobs, but for virtual machines. On the other hand, in grid computing, a cluster of computers work together to solve a … Originally, I couldn’t even tell you the meaning of virtualization or cloud computing, let alone what the differences were. private/public cloud, also called a hybrid cloud. 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, Cloud computing is a rapidly evolving discipline and one that will reshape organization charts as fast as it will change data center layouts. 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. Virtualization is the establishment of cloud computing. As Steve Tuecke, CEO of Univa says: Like Grid, virtualization is a trend that's being driven by economics. The second form of cloud computing, which is a private cloud, is emerging rapidly. In the area of Grid Computing, virtualization gained more and more interest, but less in terms of service consolidation and/or increasing server utilization. Still, there is no direct link to the cloud from pure virtualization. Techspirited explains these concepts and points out the similarities and differences between them. Combining the aforementioned LRMS features (suspension, checkpointing) with migration helps the LRMS in dynamically changing the current resource allocation. Cloud computing is as much a methodology as it is a technology. CloudPassage / July 22, 2011. Cloud Computing and Virtualization are two different technologies, these technologies will work independently. 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. Development was in the early days mostly driven by specific communities requesting amounts of computational power and storage capacities. A Cloud computing refers to a client-server computing framework where resources are managed in centralised fashion. 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. 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. Today, we will study 4 types of Cloud Computing Technologies: Virtualization, Service Oriented Architecture (SOA), Grid Computing, and Utility Computing. The majority of current applications are in the area of CPU virtualization, storage virtualization and network 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. An approach more preferable is the user-based dynamic deployment of the Middleware services. Grid computing is a computational model that is Like the gLite Middleware, also other Grid Middleware’s can be packaged as virtual appliances. Companies are now beginning to establish private clouds. Virtualization is sometimes seen as the same thing as cloud computing, but it is just a part of it. Computer Network Computer Engineering MCA. They can easily isolate and partition their systems, so deciding the amount of resources they want to put in the Grid. Without virtualization there is no cloud that's what enabled the emergence of this new, sustainable industry. However, virtualization also provides new and powerful features in light of service-based infrastructures or Grids. 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. Like it? The system deploys on-the-fly VO-specific (familiar) worker nodes to execute their applications. That is virtualization. The primary focus in Grid Computing lies in secure resource sharing in terms of access to computers, software and data in a dynamic environment. While cloud computing and virtualization rely on similar models and principles, they are intrinsically different. Areas of differentiation may be the areas of self-provisioning, granular billing/chargeback and APIs. However, the idea and current trends show a broader meaning that also includes different kinds of resources. Difference between Cloud Computing and Grid Computing. It is provided as a pay per use service. This makes the resource providers’ intervention in the deployment process superfluous and he no longer has to deal with software management and application requirements. VMs are a powerful tool for Grid sysadmins also. Nodes may have different Operating systems and hardwares. Thus by using Virtual Machines, Grids can be turned in a very effective resource provisioning platform. However, this all depends on the type of business you’re looking at and the requirements. When cloud computing comes into picture only single ownership is used. 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. Virtualization is used in many different contexts, which can be grouped into two main types: platform virtualization, involving the simulation of whole computers and. Virtualization became a common technique for IT systems in many application environments. It helps to choose any device like kitchen appliances or any chip which could be embedded. Cloud computing and virtualization may be modernizing today’s IT business environment. Multiple operating system instances running on one hardware device are far more economical than a single piece of hardware for every server task. Simply put, virtualization can make one resource act like many, while cloud computing lets different users access a single pool of resources. Private cloud computing does not center on virtualization or any one technology. 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. For example, one can virtualize a desktop, meaning the desktop is stored virtually in the clouds and can access it from anywhere. Difference between Cloud Computing and Virtualization • Categorized under internet,Software,Technology,Web Applications | Difference between Cloud Computing and Virtualization. Difference Between Cloud Computing vs Virtualization. Grid Middleware development started in 1997 with the German UNICORE project. Charalambous Tower Figure 15 shows the cloud computing adoption model. Difference between Cluster and Grid Computing: Cluster Computing Grid Computing; Nodes must be homogenous i.e. 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. 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.. The trend to virtualize everything from servers to processing power to software offerings actually started years ago in the personal sector. It was extended and renamed to UNICORE Plus and reached a mature production state. ... such as virtualization, HPC, grid computing and utility computing. The difference between virtualization and cloud computing is simple enough, once you understand both terms. Virtualization and cloud computing are two terms that often seem interchangeable if you're not familiar with how either work. The system leverages virtualization technologies to provide flexible support for different VOs. The main motto of cloud computing is to provide the service at a lower rate … Because corporate IT didn't trust the lack of security of the cloud. Cloud computing takes place over the internet. Virtualization vs Cloud Computing. Now, you have cloud computing leveraging virtualization! Since we implement and support these technologies I had to understand the definitions quickly! At the end, this paper describes the similarities and differences between the Grid and Cloud approaches. Cloud computing can certainly take advantage of virtualization but cloud computing can be accomplished without the use of virtualization. They are not sure if the terms mean the same thing or how they may be linked. number of CPUs, RAM) assigned to a virtual machine are possible and allow dynamic updates in service quality. Flat M2 Once the worker node is up and running it registers in the computing element and this information is pushed to the Information Service (MDS). 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. It closely aligns with virtualization, but it takes many technologies to be successful. Getting gLite to work with other operating systems is a complex task. 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). 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. 2) Grid however is able to run a software in parallel on multiple nodes at the same … Virtualization is not a complete solution to how enterprises manage their resources. The third iteration is evolution of cloud computing i.e. Share it! Virtualization on the other hand was started within the boundaries of enterprise firewall and then was utilized in hosted environments. 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. 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 Copyright © 2005 IDG Communications, Inc. February 10, 2014. for inter-communication; Coordination of resources that are not subject to centralized control. For example, virtual desktops alone lower costs by 15%. Virtualization and cloud computing go hand-in-hand and virtualizing servers is just the tip of the iceberg. Now, in 2013, the factors that are increasing an organization's interest in virtualization are speed and agility. By encapsulating the Grid Middleware into a virtual appliance, resource providers can support the VOs with minimal effort. Cloud was implemented more of a outsourced/hosted model first and then slowly being adopted within the enterprise firewall as an architecture. 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. Practically, cloud computing is a concept created from one product, virtualization. Depending on a predefined set of policies and the actual Grid load, an Infrastructure Manager deploys VO-specific worker nodes in the Grid computing elements. 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. The second great value of virtualization is that it's great at suspending, resuming and migrating images around an IT environment, in run-time. “The next big thing will be grid computing.” ― John Patrick, Vice President for Internet Strategies, IBM When we want to solve a computing proble… The two processes should go hand-in-hand, though they just as often end up competing with each other. Virtualization. That's the power of virtualization. Also we have to add in practices and policies that govern chargeback, monitoring, procurement and many other facets of our IT infrastructure. Automated policies can then assess risk and immediately initiate remediation with security problems arise. Figure 14 shows that the architecture, developed for dynamic provisioning of computational services in grid. Virtualization breaks the bond between processing and physical machines, cloud computing enables the use of scalable processing facilities offered by online providers, through virtualization. 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 received a big push in 2009 and 2010 because of the recession, which prompted many companies to cut their IT budget. Like Grid, virtualization is a trend that's being driven by economics. Conversely, the virtualization is used to construct multiple simulated environments through one physical hardware system. By offloading hardware requirements and utility costs, it can rapidly transform a company’s infrastructure and improve its efficiency by itself. However, it does provide great capabilities in managing and moving operating systems onto different hardware resources. Virtualization and Grid computing heading in similar directions. As a matter of fact, virtualization exhibits with live and deferred migration of virtual machines even one more feature. It comprises of a collection of integrated and networked hardware, software and internet infrastructure. Machines can be homogenous or heterogenous. It is, however, a fundamental technology that makes cloud computing work. The deployment of the VMs supporting the worker node is done through the Virtual Wokspace Service (VWS). Cloud Computing Technology (CCT), is emerging and benefiting a lot to organizations. Sharing of those resources has to be fine grained and highly controlled. The idea was there in the days of mainframe computing but gained increased popularity in recent years. This technology allows enterprises to use a single piece of physical hardware, to perform the work of many. 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. They have closely aligned their products with tools and complementary technologies that promote the adoption of private cloud computing. All the copies are "on" one piece of hardware (the real you). We cannot plan any single element without considering the effect on the others. Grid computing is used to build Virtual supercomputer using a middler ware to achieve a common task that can be shared among several resources. Although the two … 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. Difference Between Cloud Computing and Virtualization (1) Virtualization is a Technique but Cloud Computing is a Concept using Virtualization techniques. Server virtualization provides the capability to divide a physical server logically into many virtual servers. Integration of virtualization and Grid Computing can be impelled at different levels. Middleware’s are deployed in about 250 sites in all European countries and allows access to over 50,000 compute nodes. 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. Furthermore adjustments of resources (e.g. A given site is able to balance the physical resources allocated to each VO it is supporting. 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. To bring the two together you would take all those virtualized copies of you and beam them out over many different links to an individual(s) who would control and interact with them remotely. 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. Example middleware’s are gLite, UNICORE and Globus. 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. (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. Security in the cloud is better as a result of virtualization, makes the cloud even more secure than your physical datacenter. Virtualization is not in of itself a complete solution to how enterprises manage their resources. These infrastructures are used to provide the various services to the users. 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. Virtualization can take many forms aside from servers. 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. It is the technology that has allowed service providers to deliver lower-cost hosting environments to businesses of all sizes today. 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. When talking about virtualization, cloud computing is a natural component. 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. 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. How do virtualization and Grid relate to one another? In this configuration, users have a private part of their corporate cloud that is secure and only accessible by employees, but also they have a part of the cloud that is public where strategic partners, vendors and customers can access limited content. I'll share more thoughts on that tomorrow. ... First, it allows you to run multiple workloads on a single machine with great isolation between those workloads. Even if there are differences and similarities, many in the industry use them interchangeably. 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.
