CIS 505 Week 4 Discussion 1

Hyper Text Transfer Protocol (HTTP) or Hyper Text Transfer Protocol Secure (HTTPS) basically HTTPS is the secure version of HTTP.  The secure form encrypts all communication between the browser and the website.  HTTPS is used for the highly confidential online transactions such as banking and shopping.  The padlock icon in the web browser is an indication that HTTPS is in effect.  HTTP is a set of standards that allow users of the web to exchange information found on web pages.  HTTPS provides confidentiality, integrity, and identity. HTTP I see it will soon disappear since HTTPS provides a more secure way of communicating.  Sites that do not use HTTPS judiciously are crippling the privacy controls you thought were protecting your data. HSTS (Hyper Strict Transport Security makes sure communication is only used during HTTPS which is needed to prevent downgrade attacks and cookie hijacking.

HTTP came around when internet protocols were simple text-based.  Hackers can easily obtain information sent over HTTP because it is in plain text form.  HTTPS sends information in encrypted text format which is hard to read for hackers.  Protocols for HTTPS are SSL and TLS.  SSL or secure sockets layer and TLS or Transport Layer Security use asymmetric public key infrastructure (PKI) which uses two keys to encrypt communication.  The two keys are a public key and a private key.  An example of a private key would be replacing letters with numbers. The only way it can be deciphered if the receiver knows the key pattern.  A public key is provided by the sharing of a secret between two entities.  Such as if person A had a message for person B the keys would be sent and the encryption could only be decoded by these two people.

Inelastic traffic does not adjust its material in answer to network conditions.   Apps such as Skype, Facebook Messenger, or Google hangouts are examples of Inelastic traffic.  These apps implement free options to voice and video calls.

Elastic traffic alters its material between and end hosts in reply to network situation.  Elastic traffic is TCP-friendly.  The cloud is used in many ways and Elastic Computing is when supplies can be ascended up and down effortlessly by the cloud service provider. Cloud computing is about equipping on-demand computing resources with the simplicity of a mouse click. A number of resources which can be sourced through cloud computing incorporate almost all the facets of computing from raw processing power to massive storage space. The knack of a service provider to running malleable computing command when and wherever mandatory.  The flexibility of these means can be in relations of processing power, storage, and bandwidth.

Elastic Traffic can adjust, over wide ranges, to changes in delay and throughput across the internet and still meet the needs of its applications.  Elastic traffic was created for the internet due to its support of TCP/IP.  Organizers flourish on building innovative commodities and services to satisfy purchaser requirements, although, prices decide if a corporation earns a profit. If prices are inexpensive, businesses can’t cover their liabilities, and if costs are too great, they may not lure just shoppers to break even. Elastic demand illustrates a situation where the quantity of product consumers wants to buy is very sensitive to its price, which can be an important consideration when setting or changing prices.
