Many organizations are now looking for new ways to perform compute intensive tasks at a lower cost. Fast provisioning, minimal administration, and flexible instance sizing and capacity, along with innovative third party support for grid coordination and data management through cloud based platforms that support high performance grid computing. One can allocate compute capacity on demand without upfront planning of data center, network, and server infrastructure. You have access to a broad range of instance types to meet your demands for CPU, memory, local disk, and network connectivity. Infrastructure can be run in any of a large number of global regions, without long lead times of contract negotiation and a local presence, enabling faster delivery especially in emerging markets. One can define a virtual network topology that closely resembles a traditional network that you might operate in your own data center. One can build grids and infrastructure as required for isolation ...

This will be determined by the nature of the cloud service offering one select. A cloud service provider will almost certainly have access to the hardware on which data is stored, but one effect of virtualized storage is that access to hardware generally does not by itself provide logical access to stored data. It is the contracts with your preferred cloud service providers limit access to authorized personnel and provide for specific procedures to be followed (and strict limitations governing)  when preferred cloud service provider personnel or contractors access your data. No matter where your data is stored or accessible, it is always possible that a regulator or court of competent jurisdiction might attempt to access data (a) maintained on a service provided by a cloud service provider that is within its jurisdiction, (b) accessible by a cloud service provider or third party within its jurisdiction or (c) maintained on computing equipment within its jurisdiction. In appro...

This is more to do with the approach to the security responsibility issue. Because many standard security controls are applied at the application layer or in the data store, both of which are typically owned by whoever controls the software application, often the customers retain control of and responsibility for many specific security functions. In the IaaS and PaaS models, many standard security controls, such as backups, encryption, access management, logging attributes and IDS , must be provisioned and executed by the customer. If you see the responsibility for cloud security is generally allocated with the preferred cloud service providers, and you. The manner in which this responsibility is delegated will depend on the specific solution designed provide the cloud service. Specific categories of requirements correlate to which party controls which portion of the computing infrastructure customer or the cloud service provider. For instance, the preferred cloud service ...

WAN optimization offers clear benefits today, so it is logical that this will continue in parallel with the move to cloud computing. Will cloud computing drive new WAN optimization services and innovation? Yes. As cloud computing matures over time, WAN optimization technologies must respond with: Virtualization options: As large organizations move through the enterprise and dynamic phases, they will virtualize applications and not just servers. This means that Web, application, and database servers will be grouped together as virtual applications that run as VMs and move around the cloud infrastructure in unison. This could improve resource utilization, but what happens to end-user performance when a virtual application hosted in   New York City   moves to   Berlin ? To address this type of dynamic IT in the future, virtual applications must be supported and accompanied by virtual WAN optimization appliances as they move around the network. Ideally, virtual WAN opt...

A grid infrastructure may not be the case for certain organizations. The reasons for this may be one of enterprise size, IT policy, outsourcing model, lack of budget, or ISV certification. In these circumstances it is generally recognised as good practice for applications with non-intensive workloads to use server virtualisation in order to consolidate. However, where maximising consolidation, availability and agility are of paramount importance, a combination of server virtualisation and grid-based solutions are the best way to maximise the benefits of consolidation, availability and agility. Working in tandem, they can ensure enhanced server virtualisation, the ability to dynamically scale within and across nodes, and the dynamic resizing of virtual nodes. Compared to other models of computing, IT systems designed and implemented in the grid style deliver a higher quality of service, at a lower cost, with greater flexibility. Higher quality of service results from having n...

The business world is adopting an on-demand model, and for a very good reason: the business environment is changing faster and becoming more unpredictable. That leaves us with a choice to incorporate the change in our core business or spend money, time and effort in exploring the past trends. How many times has it happened in the past? We made our cost benefit analysis, the savings looked terrific, the solution got implemented, and life was happy go lucky. Then the reorganization happened, the planning went out of window, and now we’re saddled into an IT infrastructure system that doesn’t fit the new situation we are in now. That’s business today. Even the list of things that are changing is changing. What we need is a solution that’s designed for change. What we need is an on-demand business model. We need to be able to change with a change in the IT infrastructure system. And if, the IT infrastructure is an important part of your bus...

Having survived Enterprise Application Integration (EAI) and Business-to-Business integration (B2Bi) projects, enterprises are looking for fresh ways to accelerate business and to increase efficiency and agility. Web services, a set of technologies that automate business processes,promise the speed and agility that enterprises seek to create a competitive edge. Unlike previous technological innovations that required re-engineering work or hands-on intervention from end users in order to effect changes, Web services are layered onto existing applications and are themselves self-adapting, capable of discovering and querying one another automatically, and able to connect, compare, assess, re-configure, and transact as quickly as business needs demand. The result is an unprecedented degree of automation, efficiency, and agility. Constellations of business connections and trading networks can appear overnight as Web services automatically pursue opportunities that even the most diligent h...
