Hybrid cloud boost: IBM unveils new servers, software and solutions

IBM Corp has announced new servers, and storage software and solutions that it said would help more clients create hybrid cloud computing environments.

Businesses are increasingly adopting hybrid cloud environments to integrate existing technology investments (systems of record) with new workloads in the cloud (systems of engagement), driven by mobile, big data and social computing, IBM said in a statement.

These systems bring new waves of data that can make moving computing workloads around a challenge because they reside in a variety of on-premises data centres and inside public and private clouds.

The combination of IBM Power Systems, Spectrum Storage, Middleware, SoftLayer and OpenStack software can help clients more simply navigate between these environments and gain valuable insights on key business data, the company claimed.

“IBM hybrid cloud solutions are built for the enterprise and clients are using them to help enable new business models to drive growth,” said Don Boulia, vice president of Cloud Services, IBM Systems.

“Hybrid cloud computing requires new levels of openness, dynamic data management, integration, automation and scalable performance in server, storage and software technologies.

“IBM brings all of these technologies together from on-premises data centres and inside public and private clouds to more efficiently manage traditional computing with new mobile, big data and social computing workloads,” he claimed.

The new products include:

  • IBM Power System E850: The industry’s first 4-socket system with flexible capacity and up to 70% guaranteed utilisation, aimed at cloud service providers or medium and large enterprises looking to securely and efficiently deploy multi-tenancy workloads.
  • IBM PurePower System: Offers secure, quick-to-deploy compute, networking and storage converged infrastructure for a cloud with open choice.
  • IBM Spectrum Control Storage Insights: Building on its US$1-billion investment in IBM Spectrum Storage, this new Software-as-a-Service solution provides data management as a hybrid cloud service to optimise on-premises storage infrastructures.
  • IBM XIV GEN 3: New system designed for the cloud with IBM Real-time Compression that dramatically reduces total cost of ownership, the company claimed. IBM’s XIV grid architecture integrated real-time compression technology can store 50% to 80% more data and with little or no application impact.
  • Big Storage Technology: A technology preview of a new active cloud archive service for clients to store large amounts of data and easily retrieve it on demand, at the lowest cost possible.
  • Rocket’s Mainframe Data Access Service on Bluemix: Provides clients a simple, seamless and secure connection to data on the IBM z Systems mainframe for development of new mobile and hybrid cloud apps through Bluemix. Starting in June, clients can access a free trial of the service, which provides universal access to the data, regardless of location interface or format.

Many IBM Software products are available for monthly licensing, including its WebSphere Application Server starting at US$166 per month, per core. Clients can freely move monthly licences between on-premises and public and private clouds as needed, including on IBM SoftLayer and third-party clouds.

IBM said its clients are cloud-enabling their existing enterprise applications and deploying across on-premises and hybrid cloud environments without changing these applications using IBM PureApplication Service on SoftLayer.

In June, IBM will deliver a self-service portal for clients to scale their infrastructure and software licence footprint for hybrid deployments in minutes using PureApplication Service.

IBM said it is also offering try-before-you-buy access to key middleware software products for hybrid cloud computing. For a limited time, clients can use WebSphere Application Server on-premises and run the same capacity in a public cloud at no charge.


Although Cloud Computing is a great tool in the world of computing, there also exist disadvantages of cloud computing. Some of them are discussed below:


It is the biggest issue about cloud computing. Since data management and infrastructure management in cloud is provided by third-party, there is always a risk to hack the sensitive information to such providers. Although the cloud computing service provider provide more secure authentic password protected accounts, any sign of security breach may result in loss of clients and businesses. Although cloud service providers implement the best security standards and industry SSL certifications, storing data and important files on external service providers always opens up risks. Using cloud-computing technologies means you have to provide your cloud service provider with access to business data. Records, being a public service opens up cloud service providers to security challenges on a routine basis. The ease in obtaining and accessing cloud services can also give sinful users the ability to scan, identify and explore loopholes and vulnerabilities within a system. For instance, in a multi-user cloud architecture where multiple users are hosted on the same server, a hacker might try to break into the data of other users hosted and stored on the same server. However, such Loss of data and important information are not likely to surface, and the same as of a compromise is not good.


It is very difficult for the user or client to switch from one Cloud Service Provider (CSP) to some other. It cause dependency on a particular CSP for service.


This risk involves the failure of isolation mechanism that separates storage, memory, routing between the different VM machines. Sometime it very difficult to take backup of huge amount of data.


Since the cloud infrastructure is totally owned, managed and controlled by the service provider, it moves minimal control over to the customer. The customer can only control and manage the applications, data and services operated on top Layer, not the backend infrastructure itself. Key administrative tasks such as Secure Shell, server shell access, updating firmware management may not be passed to the customer or end point user. It is easy to see how the advantages of cloud computing easily overcome the drawbacks. Less costs, reduced time, and less management tasks are benefits that speak for themselves.

What is Hybrid Cloud Computing

What is a Hybrid Cloud (Definition of Hybrid Cloud)

Hybrid cloud computing is combination of both private and public cloud computing. It can take securities from private cloud model and user access from public cloud model and can perform both functional individually or simultaneously it combine two model together to enable application and data.  Therefore, Company can maximize their performance by employing public cloud services for all less sensitive operations, only switching on a private cloud where they require it and making sure that all of their platforms are properly integrated.

The Hybrid Cloud is mixture of public and private cloud. However, the secure activities are performed using private cloud while the normal activities are performed using public cloud.

By using public cloud services, users can use cloud solutions for specific functions that are very costly to handle on-premise such as virtual server backup’s, server recovery, and test/development environments.

Hybrid cloud models implementation:

– Different cloud providers provide both private and public services as dual service.

– Individual cloud service providers offer a complete hybrid package on single Platform.

– Companies who manage their private clouds themselves login to hybrid cloud service which they then change into their private cloud.

Advantages of Hybrid Cloud Model:

Scalability:  Private clouds provide some level of scalability based on their configurations (may be they are hosted internally or externally), public cloud services will offer scalability with less area boundaries because resource is moved from the larger cloud infrastructure. By moving as many non-sensitive functions as possible to the public cloud it permit us to benefit from public cloud scale when reducing the demands on a private cloud.

Cost efficiencies: Public clouds combine together greater levels of resource and so can benefit from the largest economies of service scale. The main operation and management of these resources is shared across all of the cloud services components, such as hosts, servers, and storage. We can take monthly payment access service. If I take an example of Tata Sky daily recharge service we can watch channel on daily base subscription.

Security: The private cloud element of the hybrid cloud model not only provides the security where it is used for tunable operations but can also satisfy regular requirements for data handling and storage where it is applicable. We can use SSL securities for providing user end point security.

Flexibility: This allows systems and services to be accessible by group of organizations. The presence of both scalable and secure public resource can provide chance with more opportunities to explore different operational values.

Infrastructure as a Service (IaaS), Platform as a Service (PaaS) & Software as a Service (SaaS)

1) Infrastructure as a Service (IaaS)

2) Platform as a Service (PaaS)

3) Software as a Service (SaaS)

1) IaaS

It is a network end part .It is a basic cloud-service that provide computers – physical or (more often) virtual machines – and other resources. Here you are provided the physical infrastructure (Server, RAID Storage, and Virtual Network) by cloud provider by which you can access over internet.  IaaS clouds often offer additional resources such as a virtual-machine .iso disk image ,  block storage, and file or object storage, firewalls, Boot Devices, Plug and play, IP addresses, virtual local area networks (VLANs), and software bundles. IaaS-cloud providers supply these resources on-demand from their large pools installed in data centers. For WLAN and LAN, customers can use either the Internet or virtual private network over cloud.

2) PaaS

It is a developer end part. PaaS, is a category of cloud computing that provides a platform and environment to allow developers to build applications and services over the internet. PaaS services are hosted in the cloud and accessed by users simply via their web browser Platform as a service provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering web-based (cloud) applications—without the cost and complexity of buying and managing the underlying hardware, software, provisioning and hosting. In PaaS models, cloud providers deliver a computing platform, typically including operating system, programming language execution environment, database, and web server. Application developers can develop and run their software solutions on a cloud platform without the cost and complexity of purchasing and managing the hardware and software layers.    PaaS offering supplies an operating environment for developing applications. In other words, it provides the architecture as well as the overall infrastructure to support application development. This includes networking, storage, and software support and management services. It is therefore ideal for the development of new applications that are intended for the web as well as mobile devices and PCs.

3) SaaS

This is a user end model .SaaS is a distribution model that provide software applications over the Internet; these are often called Cloud or Web services.  We can take Microsoft Office 365, one drive, dropbox is a SaaS offering for productivity software and email services. Users can access SaaS applications and services from any location using a computer or mobile device that has Internet access.  In traditional model we use Software as a product service of software distribution, in which software is purchased for and installed on personal computers, is sometimes referred to as software as a product. There are various benefit of saas model in cloud computing like easier control, automatic updates and patch management, local and global accessibility and all user can use same version of software with up to date Patch.



Private cloud definition

Private means not publicly access to all user. A private cloud is a specific model of cloud computing that intake a different and secure cloud based environment for specified client login. Correspond to other cloud models, private clouds will provide computing and services as a service within a virtual atmosphere using pool of physical resource of computing and hosting. However, in the private cloud model, the cloud is only accessible by a single organization and user providing that organization with greater control and privacy.

We can use various authentication techniques for making cloud private. Virtualization is the key of cloud computing .For example, a private cloud service may be used by a software company that is required to store private data internally and who will still want to benefit from some of the advantages of cloud computing within their business infrastructure, such as on demand resource allocation.

The private cloud model is near to the more TCP model of personal local access networks (LANs) used in the past by enterprise but with additional benefits of virtualization.

Private cloud software and private cloud providers include Microsoft private cloud (mcse private cloud & azure private cloud). Private cloud hosting and private cloud storage are very important in todays world.

The features and benefits of private clouds are:

  • More security and privacy: Public clouds services can use a certain level of security but private clouds – using techniques such as different parameter of resources with access restricted to connections made by one organization’s firewall, dedicated leased lines and/or on-site internal hosting – can make sure that operations are kept out of the reach from unauthorized access.
  • Private control: Private cloud is only authorized by a single organization, that organization will have the power to configure and control it in line with their needs to achieve a secure network solution for IT enterprise. However, this level of control removes some of the access generated in public clouds by having central management of the software and hardware.
  • Efficiency: Private cloud model are very efficient and can maintain the usage of resources within an organization by making the reachability of resources to individual departments/business functions can directly and flexible respond to their needs. Therefore, they are not as cost effective as a public cloud services due to smaller level of scale and lower management costs, they do make more efficient use of the computing resource than traditional LANs as they minimize the investment into unused capacity. Not only does this provide a cost saving but it can reduce an organization’s server load and power Waste problems.
  • Reliability: Private cloud network are more reliable using virtualization by which resources (servers, networks etc.) are used and hosted internally, the creation of virtualized operating environments means that the network is more reliable to single failures across the physical layer. Virtual partitions can, for example, we can use our resources from the remaining unaffected servers.



Cloud computing can also play an important role in biomedical industry for providing a healthcare solution. The aim of this guide is to provide a practical reference to help enterprise information technology (IT) and business decision makers of the healthcare industry as they analyze and consider the application of cloud computing on their business.  The main aim of this article is to analyze different different requirements from various factors including medical practices, hospitals, research facilities, insurance companies and governments.

When considering a move to use cloud computing, healthcare consumers must have a clear understanding of unique benefits and services associated with cloud computing, and set realistic expectations with their cloud provider. Consideration must be given to the different models of service delivery: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS) as each model brings different requirements and responsibilities.

More and more cloud vendors are offering healthcare solutions and services such as telemedicine, electronic medical records, medical imaging, and patient management that can be consumed or integrated by healthcare providers, payers and customers over a cloud.

Service providers play a major role in adoption of cloud in Health industry. Cloud can enable service providers to rapidly and cost-effectively integrate their applications, end points, and operations capabilities into a set of cloud services that can be deployed to customers, be it providers, governments, payers, or patients, using a wide range of network connections (fixed and mobile

Benefits of cloud computing in healthcare industry are

 Record and Protect Patients’ Information Safely

24*7 medical services to patients

Single platform for medical professional and doctors

Store Data with Less Cost

 Share Records to Authorized People

Live help for operation and medicine enquiry

The world is fast changing. At the heart of this change are cloud technologies that are also being accepted by the health care industry. Cloud computing which enables computers and various other mobile devices to access shared files and applications online through the Internet instead of the local environment. Medical professionals now can share and promote information among others in similar fields in different locations. It is also important to point out that offices do not have to be hospitals or big enterprise medical clients to take advantage of the cloud. In fact, it is even more important for the smaller offices (medical specialty clinics, dentists, orthodontist, etc.) because they now have access to enterprise level security, backup and encryption at a fraction of the cost. If a take an example of cloud 9 ortho, Cloud9Ortho has been solving issues for orthodontist. So we can take lot of benefits of cloud computing in health care industry just as IT industry.

List of cloud Computing Companies







Cloud computing i.e. computing from cloud means taking services remotely from cloud. Cloud means Service provider which provide us services on single platform. latest best example of cloud computing is Pay as you use services .suppose you have a company and you want to take storage , operating system , maintenance , support and other services for 3 month  then you need not go for  each set up of service at your office . You can take these services from cloud services provider. You can take services according to your choice. or you can say Cloud computing, often referred to as simply “the cloud,” is the delivery of on-demand computing resources—everything from applications to data centers—over the Internet on a pay-for-use basis.

Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). Cloud computing work on cloud architecture based on cloud engineering. Cloud engineering is the application of engineering disciplines to cloud computing. It brings a systematic approach to the high-level
concerns of commercialization, standardization, and governance in conceiving, developing, operating and maintaining cloud computing systems. It is a multidisciplinary method encompassing contributions from diverse area such as systems, software, web, performance, information, security, platform, risk, and quality engineering.

Features of clouding Computing

Cost: A public-cloud delivery model converts capital expenditure to operational expenditure. You can use pay as you services

Maintenance : Maintenance of cloud computing applications is easier, because they do not need to be installed on each user’s computer and can be accessed from different places.

Multitenancy:  it enables sharing of resources and costs across a large pool of users Performance is monitored, and consistent and loosely coupled architectures are constructed using web services as the system interface.

Productivity : Productivity may be increased when multiple users can work on the same data simultaneously, rather than waiting for it to be saved and emailed. Time may be saved as information does not need to be re-entered when fields are matched, nor do users need to install application software upgrades to their computer.

Reliability: reliability improves with the use of multiple redundant sites, which makes well-designed cloud computing suitable for business continuity and disaster recovery.

Security: we can use various authentication techniques for providing security to user

What is Public Cloud


                                      image: public-cloud-example

Public cloud definition

Public cloud is a cloud in which Cloud infrastructure is available to the general public. Public cloud define cloud computing where dynamically allocated resources are on an on-demand, self-service basis over the Internet, via open API,  web apps/web servers, from a service provider .Public cloud is general access to cloud computing.

What is public cloud computing

Public cloud computing is based on pay as you service. We can take on demands services. Public clouds can also typically be extend much faster and with greater accessibility than on-infrastructure. Public cloud user may pay pay-as-you-go fees or fixed monthly fees for the public cloud services. It is just like a taking service charge remote access as on demand. In Public cloud we can use single platform services on multiple devices. So some time public service cloud is also called Polyservices cloud. There are a lot of public cloud providers available. Example of public cloud is Amazon, Rackspace, IBM, Softlayer, Google, Microsoft etc

The examples of cloud computing is fall into the public cloud model because they are, publicly available by definition. Software as a Service (SaaS) offerings such as cloud storage and online office applications are perhaps the most familiar, but mostly available Infrastructure as a development environments, can follow the model as well (may also exist in private cloud). Public clouds are used in enhance for offerings private individuals who are less likely to need the services.

Benefit of Public Cloud:
Cost effect on service: public clouds combine together greater levels of resource and so can benefit from the largest economies of service scale. The main operation and management of these resources is shared across all of the cloud services components, such as hosts, servers, and storage. We can take monthly payment access service. If I take an example of Tata Sky daily recharge service we can watch channel on daily base subscription.

Reliability: Public cloud network are more reliable using virtualization by which resources (servers, networks etc.) are used and hosted internally, the creation of virtualized operating environments means that the network is more reliable to single failures across the physical layer. Virtual partitions can, for example, we can use our resources from the remaining unaffected servers.

Flexibility: Services of Cloud like IaaS, PaaS and SaaS available on the market which follow the public model of cloud and that are ready to be accessed as a service from any internet connected device. These services can fulfill most computing requirements and can deliver their benefits to private and enterprise clients and Multihome users. Businesses can even integrate their public cloud services with private clouds, where they have to perform sensitive business functions, to create secure hybrid clouds

Location independence: Public clouds are location independent. User can take access from any remote location.

Other types of clouds are private, personal and hybrid. Contact us for public cloud UK
