Cloud computing describes the use of networks of remote servers – usually accessed over the Internet – to store, manage, and process data. As a segment of IT services, cloud computing generates billions of dollars in revenue annually and is showing very few signs of slowing down. For customers, cloud computing offers access to numerous technologies while lowering the barriers to entry, such as technical expertise or costs. Typically, the cloud service market is divided into three primary service models, encompassing infrastructure, platforms, and software. Depending on business needs and security concerns, customers can also choose between private, public, or hybrid cloud deployment.
IPv6 is good for IoT and IoT is good for IPv6. There are several arguments and features that demonstrate that IPv6 is actually a key communication enabler for the future Internet of Things:
Adoption is just a matter of time
The Internet Protocol is a must and a requirement for any Internet connectivity. It is the addressing scheme for any data transfer on the web. The limited address capacity of its predecessor, IPv4, has made the transition to IPv6 unavoidable. Google’s figures are revealing an IPv6 adoption rate following an exponential curve, doubling every 6 months.
IPv6 offers a highly scalable address scheme. The present scheme of Internet Governance provides at most 2 x 1019 unique, globally routable, addresses. This is many orders of magnitude more that the 2 x 109 that is possible with IPv4 and the 1013 that is the largest estimate of IoT devices that will be used this century.
Solving the NAT barrier
Due to the limits of the IPv4 address space, the current Internet had to adopt a stopgap solution to face its unplanned expansion: the Network Address Translation (NAT).
IPv6 provides for end devices to have multiple addresses and an even more distributed routing mechanism than the IPv4 Internet.
