How to Decode TLV Quickly

In TLV, the format is Tag, Length, and Value. The TLV protocol needs this type of data. Here you will know how to decode TLV data. According to IBM , TLV data is three parts. The tag tells what type of data it is. The length field denotes the length of the value. The Value-field denotes the actual value. Structure of TLV. TLV comprises three field values.  Tag Length Value EMV formulated different tags. They have their meanings. Usually, the Tag and Length together takes 1 to 4 bytes. The Best example for TLV. In the below example, you can find the sample TAG, LENGTH, and VALUE fields. [Tag][Value Length][Value] (ex. " 9F4005F000F0A001 ") where Tag Name =  9F40 Value Length (in bytes) =  05  Value (Hex representation of bytes. Example, "F0" – 1-byte) =  F000F0A001 In the above message, tag 9F40 has some meaning designed by EMV company. Here  you can find a list of EMV Tags. How to read the TLV Tag: 1 or 2 bytes Length: Length of the Value. F0-00-F0-A0-01 ==> 5 By

IBM - Open Cloud Architecture

Cloud computing is changing the way we think about technology, and it’s no passing fad. Consumers are using the cloud to store music. Startups are turning to cloud to get up and running without huge investments. Big businesses and governments are relying on clouds to make more data more accessible. 

Cloud computing.

is changing how business and society run, and it's opening up huge avenues of innovation. We are looking at how developers are now combining systems of record with systems of engagement, and we see a new style of cloud-based application emerging.

These are systems of interaction. For these applications to be sustainable, cloud computing needs to be built on open source and standards.

Wide adoption of open source software and open standards should be everyone's goal. It means customers won’t have to fear vendor lock-in, and organizations can participate in a growing market that welcomes a wide variety of cloud technology and service providers.

We've learned through our experience that open source and standards allow developers to share information more quickly and easily, and at lower costs. This leads to greater innovation. We are at an inflection point. We're focusing the industry on important standards for interoperability, and their open source reference implementations will:
  • Ensure that end users have a strong voice in establishing and adopting cloud computing paradigms
  • Reduce barriers of entry into cloud computing, such as development skills and freedom of choice
  • Increase the long-term viability of today’s cloud investments
  • Prevent unnecessary architectural complexity and fragmentation.
  • Openstack is a software to control your cloud

Open-stack software 

It controls large pools of compute, storage, and networking resources throughout a datacenter, managed through a dashboard or via the OpenStack API. OpenStack works with popular enterprise and open source technologies making it ideal for heterogeneous infrastructure.

Hundreds of the world’s largest brands rely on OpenStack to run their businesses every day, reducing costs and helping them move faster. OpenStack has a strong ecosystem, and users seeking commercial support can choose from different OpenStack-powered products and services.
