Cloud computing is a computing model where users access ICT services and resources without regard to where the services are hosted. Communication resources often become a bottleneck in service provisioning for many cloud applications. Therefore, data replication which brings data (e.g., databases) closer to data consumers (e.g., cloud applications) is seen as a promising solution.

In this paper we present models for energy consumption and bandwidth demand of database access in cloud computing datacenter. In addition we propose an energy efficient replication strategy based on the proposed models which results in improved Quality of Service (QoS) with reduced communication delays…

ITaaS is an IT operational method, providing an enterprise with the required amount of hardware, software, and support. Nowadays, companies have been using the ITaaS model to increase the usage of virtualization as it is not limited to cloud computing technology models such as SaaS, PaaS and IaaS.

Various benefits associated with the ITaaS model include the simplification and standardization of products and services delivered by IT, reduced cost of consumption, increased IT efficiency, and improved financial transparency, which leads to an increase in business agility and flexibility at the same time.  Analysts forecast the Global IT-as-a-Service Market to grow at a CAGR of 31.0 percent over the period 2014-2019…

Environmental applications of space-derived data typically require the integration and fusion of multiple diverse datasets. Increasingly many such datasets are being made available at no cost and with liberal licences enabling wide reuse.

These data encompass both scientific data about the environment (from the ESA Climate Change Initiative, the present and future Sentinel missions and from other observing systems) and other public sector information, including diverse topics such as demographics, health and crime. Many open geospatial datasets (e.g. land use and mapping) are already available through the INSPIRE directive and made available through infrastructures such as the Global Earth Observation System of Systems (GEOSS)…

At one point of time, we were looking into seeing as to why we consider cloud computing as the future and now we are in the phase where we can discuss the future of cloud computing in London. According to me, there are many ways in which the cloud computing can contribute in an efficient way to our society.

Defining And Comparing Cloud Services

With the growing number of cloud service providers that are available in the market, we may have to be defining and comparing the cloud services that are being offered in order to choose the best one for us. The increasing number of cloud service brokers is also an indication that there are many changes that will be coming in this field…

Change is the only constant. In an ever-changing IT landscape, CIOs have to constantly meet business challenges through efficient IT adoption. With wide scale proliferation of Cloud-based solutions, there is a dramatic shift from traditional in-premise implementations towards cloud-based solution. As CIOs are actively taking their organization’s business to the cloud and adopting disruptive technologies like mobile computing, the IT service companies too have to evolve and align their offerings, capabilities and delivery models to cater to the enterprise of the future.

Enterprises have changed their focus on IT investment from capex to opex, which has resulted in more services based business spend rather than on IT infrastructure. Due to this trend the traditional or core IT services like ERP implementation, Applications Development, support and maintenance etc. have reached a plateau and are on decline in terms of enterprise spends…

Outsourcing and cloud computing are first cousins if not siblings. No, they are not idential twins, but any broad discussion of outsourcing is heavily laced with cloud computing.  So it was with substantial interested I read "10 outsourcing trends to watch n 2015" over at CIO.com.

The story hits on some interesting trends such as the end of RFP model for outsoucing contracts. "Imagine floating a ‘request for food’ every time you’re deciding on a restaurant," says Pratham Mittal co-founder of VenturePact, a marketplace connecting providers with customers. No, I cannot imagine that…

I saw more discussion on big data at CES 2015 this week, compared to previous years. Everyone talked about data as the central core of everything. The IoT (Internet of Things), NFC (near Field Communication) and M2M (Machine to Machine) communication are enabling pieces for many industries  – security monitoring, asset and inventory tracking, healthcare, process control, building environment monitoring, vehicle tracking and telemetry, in-store customer engagement and digital signage. Big data is the big deal here.

The Big Data ecosystem includes – cloud computing, M2M/IoT, dumb terminal 2.0 (devices getting dumber – more cloud, better broadband, less about storage and more about broadband access and high quality display), and analysis. The big data business is slated to be a $200B business in 2015. Every company must insert the big data ecosystem into their future roadmap or get left out. The key here is not the technology, but its business value…

Cloud computing adds flexibility to enterprise IT. When companies wish to take advantage of this, they are finding they need to turn to microservices instead of their traditional, monolithic architectures to accommodate frequent change.

Microservices can overcome the challenges presented by frequent change, "by splitting monoliths into multiple independent services, each with its own simple business logic," according to Sergey Sverchkov, a Solutions Architect with Altoros. Doing so leads to another issue: "choosing either PaaS or IaaS for microservices is an open question, " he says…

Essentially virtualization means to hide the physical object from user and present to him a copy of underlying object. This object can be anything like hardware, servers, or network. In between real object and the end user, they resides a intermediate layer which provides view of real object to user as per his/her requirement.

For example, same hardware is allocated to many users and they install operating systems of their choice on that hardware to use it. Even though there is only one consistent copy of hardware, every user will see it as his copy when accessing through his operating system. Intermediate layer in this case will be software like Virtualbox or VMware etc…
