Wi-Fi has become such an amazingly successful technology because it has continuously advanced while remaining backwards compatible. Every few years since the 802.11b amendment was ratified, the industry has released successive amendments increasing Wi-Fi data rates and capabilities, but even the latest Wi-Fi systems are able to interoperate with 1999 equipment built to the original
Today we see 802.11n as the standard interface on PCs, tablets, smartphones and other networked devices. This proliferation of Wi-Fi interfaces means more mobile devices and their associated data (including HD video) find themselves on corporate networks, while the capacity and data rates enabled by 802.11n may at times seem barely adequate to support this
Novarum conducted performance tests with current enterprise 802.11ac wireless LAN systems from Aruba and Cisco. This testing goes beyond simple drag race throughput tests by looking at real world scenarios involving high-density throughput and client roaming as well as real applications including VLC media streaming.
The all-wireless workplace is all about mobility. It has to be. Today there are more Internet-connected mobile devices than people. Workplaces should be architected so that every class of user – employees, contractors, customers and guests – gets seamless connectivity appropriate to their role and type of device.
In the past few years, the enterprise computing landscape has changed dramatically. Virtualization, outsourcing, SaaS and cloud computing are creating fundamental changes, and ushering in an era in which enterprises distribute increasingly critical IT assets and applications across multiple service providers. These changes are rendering legacy monitoring tools, which have their roots in the computing
Monitoring IT operations is made costly and inefficient due to the presence of multiple, complex monitoring solutions. These legacy systems have a silo view of the IT environment creating unnecessary complications when trying to resolve infrastructure and availability issues. While system administrators are attempting to resolve these problems the customers and their business are suffering.
These tech-enabled, highly connected buyers are using many different platforms to research, shop, and work, forcing IT leaders to create differentiated customer experiences and support new technologies, such as client mobility and cloud services. At the same time, the growing use of agile development techniques and the move towards an “app economy” are accelerating the
This paper argues that DevOps can be implemented productively if the two disciplines adopt a “cloud” model for production and consumption of services. It also argues that Linux containers are a very powerful and convenient technology change to enable this model as long as they are used with appropriate automation and management technologies.
Every 2 days the world generates as much data as it had through all of history up to the year 2003. By 2020, the world will have generated an astonishing 40 zettabytes, or 40 trillion gigabytes, of digital content. “Data is the new natural resource,” says Ginni Rometty, IBM Chairman, President and CEO. Enterprises are
IT virtualization, the engine behind cloud computing, can have significant consequences on the data center physical infrastructure (DCPI). Higher power densities that often result can challenge the cooling capabilities of an existing system. Reduced overall energy consumption that typically results from physical server consolidation may actually worsen the data center’s power usage effectiveness (PUE). Dynamic
