BIG-IP

Certified Big-IP LTM admin here. Big-IP is a product suite related to accelerated data delivery, created by company F5. This is everything from basic application delivery (think web acceleration and load balancing) to data distribution across SANs to assist in migrations and consolidations.
In my experience, people use Big-IP to refer to their flagship product, the LTM devices which are full proxy load balancers.
People have much love for the product line because of their powerful iRules language, which allows incredible customization of whatever you are accelerating (such as a web farm).
Other reasons people recommend the product is their fantastic SSL offloading, which allows the web servers to focus on serving data, not encryption/decryption, the fact that their web interface is intuitive and stable, a powerful, linux based backend for cron jobs, and the bigpipe command line interface for scripting the creation of farms (called pools in bigip lingo).
I used Juniper and Foundry load balancers extensively and IMHO (and many others), the LTM is best in class.

BIG-IP is essentially a network load balancer or Layer 4-7 switch. They are made by F5. They have additional features which allow to use it as a Firewall, SSL VPN appliance and other network appliance type functions. In comparison Cisco’s ACE, Citrix NetScaler, Foundry/Brocade Server Iron and a few others provide similar load balancing services.

Cisco VMDC Cloud Infrastructure with F5 BIG-IP Local Traffic Manager

Design recommendations for using F5 BIG-IP Local Traffic Manager (LTM) within
the Cisco Virtualized Multiservice Data Center 2.3 (VMDC) solution in order to provide server-load balancing services. This document is based on lab validation of server-load balancing using F5 BIG-IP LTM in a Cisco VMDC 2.3 test environment.
This design incorporates both physical and virtual edition F5 BIG-IP LTM devices. The design uses BIG-IP 5200v devices, which are located at the edge of the network in order to take advantage of their high-performance hardware offload. The LTM virtual editions were used within each tenant and used 1 Gbps licenses running on VMware vSphere.
The audience for this document includes technical and business decision-makers who are interested in:

  • The design of a cloud ready infrastructure with F5 BIG-IP LTM devices in the overall cloud model.
  • Enabling IT innovation to meet their overall business strategy.

Reddit

Reddit /ˈrɛdɪt/,[6] stylized as reddit,[7] is an entertainment, social networking, and news website where registered community members can submit content, such as text posts or direct links, making it essentially an online bulletin board system. Registered users can then vote submissions up or down to organize the posts and determine their position on the site’s pages. Content entries are organized by areas of interest called “subreddits.” The subreddit topics include news, gaming, movies, music, books, fitness, food, and photosharing, among others.

Reddit was founded by University of Virginia roommates Steve Huffman and Alexis Ohanian in 2005. Condé Nast Publications acquired the site in October 2006. Reddit became a direct subsidiary of Condé Nast’s parent company, Advance Publications, in September 2011. As of August 2012, Reddit operates as an independent entity, although Advance is still its largest shareholder.[8] Reddit is based in San Francisco, California. In October 2014 reddit raised $50 million in a funding round led by Sam Altman and including investors Marc Andreessen, Peter Thiel, Ron Conway, Snoop Dogg and Jared Leto.[9] Their investment valued the company at $500 million.[10][11]

Site

The site is a collection of entries submitted by its registered users, essentially a bulletin board system. The name “Reddit” is a play-on-words with the phrase “read it,” i.e., “I read it on Reddit.”[12] The site’s content is divided into numerous categories, and 50 such categories, or “default subreddits,” are visible on the front page to new users and those who browse the site without logging in to an account. As of May 2014, these include:[13]

Category Subreddits
Educational News, Science, Space, TodayILearned (TIL) and WorldNews
Entertainment Creepy, Documentaries, Gaming, ListenToThis, Movies, Music, NoSleep, Sports, Television and Videos
Discussion-based AskReddit, AskScience, Books, ExplainLikeImFive, IAmA and TwoXChromosomes
Humor/light-hearted DataIsBeautiful, Funny, InternetIsBeautiful, Jokes, NotTheOnion, ShowerThoughts, StandUpShots, TIFU and UpliftingNews
Image sharing Art, Aww, EarthPorn, Gifs, MildlyInteresting, OldSchoolCool, Pics and PhotoshopBattles
Self-improvement DIY, Fitness, Food, GetMotivated, LifeProTips, PersonalFinance, Philosophy and WritingPrompts
Technology Futurology, Gadgets and Technology
Meta Announcements and Blog

When items (links or text posts) are submitted to a subreddit, users (redditors) can vote for or against them (upvote/downvote). Each subreddit has a front page that shows newer submissions that have been rated highly. Redditors can also post comments about the submission, and respond back and forth in a conversation-tree of comments; the comments themselves can also be upvoted and downvoted. The front page of the site itself shows a combination of the highest-rated posts out of all the subreddits a user is subscribed to.
