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

Cloud Computing Vs Virtualization Real Differences

Servicing of computing resources you can say as Cloud computing. They charge for some amount each service used by an user. On the other hand, making multiple machines virtually by using same hardware is called virtualization. Sell all the real differences.

Public Vs Private Vs Hybrid Cloud

  1. Public Cloud: Available to the public is called the PUBLIC cloud. 
  2. Private Cloud: Available to the particular Business/Company is called PRIVATE Cloud. 
  3. Hybrid Cloud: Combination of Public and Private Clouds.

Cloud Services

  • Cloud services (remote data and computation) are exposed as simple and user-friendly web services. For example, Microsoft's ADO.NET (originally called Astoria) provides the tools to expose any data object from a collection, stored in a database or other form, as a URI to an encoded form using a standard such as JSON or ATOM representation
  • Google's AppEngine provides a way to deploy a remote Python script that becomes a web service that can access data in their BigTable database system.
  • To deliver highly available and flexible services (i.e., computation as a service), and owing to the maturity of virtualization technology, Virtual Machines (VMs) are used as a standard for object deployment in the cloud.

Virtual Machines

  • VMs decouple the computing infrastructure from the physical infrastructure. VMs allow the customization of the platform to suit the needs of the end-user. 
  • For example, in the Amazon Elastic Compute Cloud (EC2), the customer selects his/her preferred VM image (virtual appliance) from a list of various versions of Linux and Windows servers
