The networking industry has gone through different waves over last 30+ years.
In the '80s, the first wave was all about connecting and sharing; how to
connect a computer to other peripheral devices and other computers. There
were many players who developed technology and services to address that, e.g.
Novell, 3Com, Sun, IBM, DEC, Nortel. Across the industry, small islands of
various protocols were created with multiple gateways to bridge them.
In 90's and 00's, Cisco dominated the industry and did a brilliant job of
pushing the industry towards a common approach built on Ethernet. They
built a hugely successful business and ecosystem and even created new markets
like VoIP on the proposition that networking should be on a common highway.
We also saw isolation of networks from the rest of the IT infrastructure, in
the sense that software innovations continued in the se... (more)
VMware announced yesterday its plan to purchase Nicira. The deal is expected
to close during the second half of this year. It includes $1.05 billion in
cash and $210 million in assumed unvested equity awards. Nicira is a
well-known start-up company and is considered a leader in network
virtualization. It has focused on Layer 2 to deliver SDN based networking
solution for data centers. It makes a virtual switch which sits in the
hypervisor and a distributed network controller which talks to a collection
of virtual switches and controls them. It delivers intelligence at the edge. ... (more)
For a successful implementation of cloud computing infrastructure, let's
understand what is important to end-user customers of Public Cloud computing.
Instant-on Business-centric Service: Customers want virtual services made
available to them as and when their business needs, in configurations and
sizes that meet their technical requirements. Faster deployment with
self-service portal will result in quick time-to-market for the end users.
Customers want to focus on their core business and get relieved from IT
related tasks. Customers do not want to worry about software licenses, p... (more)
Deploying Cloud infrastructure is not a typical technology project. Success
of a Cloud implementation depends on governance, policies, constraints and
business relationship management. This article focuses on some basic
important areas that cannot be ignored while implementing a Public Cloud
solution. To keep it simple, let us focus on green-field implementation of a
public cloud infrastructure.
Like any other solution implementation, service providers need to focus on
four key areas: Strategy, Business processes, Technology and people skills.
Quite often, cloud implementations... (more)
Cloud Computing is an evolution of existing technologies to deliver services
to end users. Communication service providers have an early adopter
opportunity to compete with new entrants, increase their bottom line and play
a dominant role in delivering cloud services.
Service providers have seen many so-called next- generation technology waves
in the last 15 years. Cloud computing, which was seen as a new fad, has
passed the initial test. Cloud computing is for real and not a vague idea
anymore. It helps drive down costs for IT organizations by making
infrastructure more distrib... (more)
