Capgemini invests in Brazil datacenter


IT services firm Capgemini is investing R 13m ( 3.6m) in a new datacenter in Brazil which will provide private cloud services to customers based in Latin America. Citibank's proposed on-site mandate and the likely changes to U.S. immigration laws suggest the global outsourcing landscape may change forever, possibly hurting India's booming IT industry. The investment in the new site, which will be based in the São Paulo countryside town of Campinas and is the company's third datacenter in Brazil, will be made across a period of five years. According to the outsourcer, the new datacenter will be providing support to core IT environments of large clients within government, consumer products, retail and financial services. "This datacenter will allow us to offer the most innovative hybrid cloud computing [services] to our clients, as well as cost reduction, more efficiency and agility," says vice president for infrastructure and outsourcing services at Capgemini Brazil, André França.

Amazon still plans to open UK datacenter despite Brexit vote


Despite the Brexit vote, Amazon is set to open a new datacenter and create additional jobs in London and across the UK. Amazon Web Services (AWS) is pushing ahead with plans to add a datacenter region in the UK, despite the country voting to leave the European Union. Speaking at AWS Summit in London, Gavin Jackson, AWS managing director for the UK and Ireland, looked to reassure customers that despite the referendum result, which has led to uncertainty over many companies' plans for the future, Amazon is still committed to opening a new datacenter in the region by next year. Opinion: Amazon has chosen to remove encryption from its devices, and we have to move forward from there. "In light of the Brexit vote, I just wanted to reassure all of our customers that we see the UK as a fast innovator.

Three themes unify the five generations of datacenter networks detailed in this paper. First, multi-stage Clos topologies built from commodity switch silicon can support cost-effective deployment of building-scale networks. Second, much of the general, but complex, decentralized network routing and management protocols supporting arbitrary deployment scenarios were overkill for single-operator, pre-planned datacenter networks. We built a centralized control mechanism based on a global configuration pushed to all datacenter switches. Third, modular hardware design coupled with simple, robust software allowed our design to also support inter-cluster and wide-area networks.

Despite all of us regularly reading of the growth of the Internet, whether it be capacity, number of users, or breadth of applications, beyond the proliferation, and ever-shortening upgrade cycle of our mobile phones, we rarely observe a physical manifestation of such growth. Yet, it is within warehouse-sized computer facilities, the datacenters that attract the superlative hyper, that the Internet growth is physically manifest. Not only must these facilities face operational challenges arising from a large and dynamic number of users, but the continuous growth in demand upon these facilities must also be accommodated. The nature and role of the datacenter has also grown; once familiar only as an organization's facility or the ever-popular co-location and hosting facility where organizations might securely site their equipment. The warehouse or hyper-scale datacenter of the type discussed in the following paper, is a wholly recent beast, with ownership and control reminiscent of a single-task supercomputer.
