Server Cache

Posted on June 10th, 2010 by Victoria Pal in Monitoring

Server CacheWeb caching describes the process of storing frequently used objects closer to the user through browser, proxy or server cache. Caching frequently used content has a positive effect in most cases because it reduces server load, bandwidth and latency. It also helps increase the responsiveness for users on the web.

Modern browsers support caching and require most elements of a page only during the first time a user opens that page. Then CSS files, images and other media are stored in a dedicated folder. This leads to faster loading times and better user experience. The whole process happens without any input from the user.

Energy Efficient and/or Cost Effective

Posted on June 9th, 2010 by Victoria Pal in Tech

Intel released a new microserver last fall. It is quite small and features a 1.86GHz Quad-Core processor and four memory slots. It consumes 45watts when flat-out, however a 30watt dual-core version was due to be released Q1 2010. Intel's goal is to have a to have a micro server running on 25watts when idle.

Improve you websiteA site can be improved in many ways and on many levels - accessibility, usability, design, organization, promotion, loading times, availability and many more. This post is only concerned with several quick fixes, which are mostly technical, but once in place they can really make a difference.

Generate Fewer HTTP Requests

80% of the end-user response time is spent in downloading page components: html, images, stylesheets, scripts, Flash, etc.

Powered By Nature

Posted on June 3rd, 2010 by Victoria Pal in Tech

Natural power sourcesMore and more companies are becoming environmentally alert and try to minimize their carbon footprint. It is "the big new thing" for more than a decade. The IT sphere, being first in expansion and new technology adoption, is determined to go green. Datacenters and servers in the US alone represent more than 1.5% of America's electricity consumption (61 billion kilowatt-hours). A percentage which is about to double by 2011. This is a major expense to all companies, using this equipment.

Sunlight

A California based company by the name of AISO.net (Affordable Internet Services Online) is 100% dependent on solar energy. All their web servers are powered by sunlight. They don't consider that enough and go further by using Coolerado air conditioners. Water is evaporated into air in one chamber within the air conditioner, and this cools the air flowing in an adjacent chamber. Water vapor in the exhaust air holds the heat and is used for cooling the solar panes, increasing their efficiency by 15%. Their entire building is painted white, to fight of the "heat island effect". Natural light is spread through the building, compensating for artificial light, during the day. You can check AISO.net to learn about the ways the are harnessing the gifts of nature.

Server Virtualization Is Growing

Posted on June 2nd, 2010 by Victoria Pal in Tech

Server Virtualization"I think there is a world market for maybe five computers" is a famous misquote of Thomas J. Watson. The same Tom Watson, who took Computing Tabulating Recording Corporation and turned into what is today known as IBM. In essence, whoever said that the world will only need 5 computers wasn't totally wrong. Virtualization was first implemented in 1960 to aid better utilization of large mainframe hardware. 50 years later, it has grown to be part of all Fortune 100 success stories.

Lately, "fake servers" became a slightly satiric way to say "virtual servers". Why? Mainly because they are gaining a larger market share. Large enterprises were quick to adopt the virtual machines approach, while small business started late. However, by year-end 2010, enterprises with 100 to 999 employees will have a higher penetration of virtual machines deployed than the Global 500. For long years, small businesses could not afford even the entry level products, and this is what changed lately. Increased competition by server vendors has made server virtualization technology affordable to smaller companies.
