What is CDN- Content Delivery Network

Short for content delivery network, a network of servers that delivers a Web page to a user based on the geographic locations of the user, the origin of the Web page and a content delivery server. A CDN copies the pages of a Web site to a network of servers that are dispersed at geographically different locations, caching the contents of the page. When a user requests a Web page that is part of a CDN, the CDN will redirect the request from the originating site’s server to a server in the CDN that is closest to the user and deliver the cached content. The CDN will also communicate with the originating server to deliver any content that has not been previously cached.
This service is effective in speeding the delivery of content of Web sites with high traffic and Web sites that have global reach. The closer the CDN server is to the user geographically, the faster the content will be delivered to the user. CDNs also provide protection from large surges in traffic.
The process of bouncing through a CDN is nearly transparent to the user. The only way a user would know if a CDN has been accessed is if the delivered URL is different than the URL that has been requested.
  1. Faster download: Instead of going all the way to the source, visitors can download website contents stored in the nearest cache server. Cache servers replicate the exact content of the origin server, allowing visitors to download files from the nearest mirror.
  2. Smoother data transmission: As data travels through a shorter distance, the chance of downloading a deteriorated audio or video file is reduced significantly. You can now provide visitors with high-quality downloadables without compromising speed.
  3. Load balancing: Overcome network congestion by spreading the traffic over several mirrors. We regard constant website availability as one of the most crucial aspect of your operation. Hence, we will ensure that your website will be able to handle the traffic load at all times.
  4. Content Redundancy: At times, the immediate server may not be able to function normally due to hardware malfunction or system failure. As CDN exercises content duplication, your website will continue to run smoothly even when our engineers are performing routine maintenance.
  5. Constant uptime: We recognize the importance of increasing the number of unique visitors as well as encouraging repeated visits to your businesses. Make your website accessible 24/7 by having a backup server that can instantly take over the responsibilities of a faulty server.
  6. Increased scalability: Expansion is simplified as modifications to website contents are made to only one server. We will gladly support the growth of your website by providing additional mirrors at the time and location of your choice.
  7. Data integrity: When the source is updated, changes made to it will be copied by all of the cache servers. This enables you to guarantee the consistency of the files and information published.

Entities In Need Of CDN

Business firms, educational institutions and government bodies with offices operating in multiple countries will positively benefit from the implementation of the CDN technology. By reducing the load of the origin server, visitors from all over the world can enjoy the contents and services from your website hassle-free.

Use Google Apps on a BlackBerry®

Use Google Apps on a BlackBerry®

You and your users have these options for accessing Google Apps from a BlackBerry®:
  • BlackBerry® mail through IMAP. Use the BlackBerry's native mail application to access your Google Apps mail (requires using your BlackBerry carrier's Internet service).
  • Google Apps Connector for BlackBerry® Enterprise Server. Synchronize users' Google Apps mail, calendar, and contact data with your organization's existing Blackberry® Enterprise Server.

Set up BlackBerry® mail via IMAP

This method is no longer officially supported but we're happy to provide setup instructions, anyway.
You can access your mail from the native BlackBerry® mail application by setting it up as an IMAP client for your Gmail account. Using IMAP is nice in that doing something on the BlackBerry, such as reading or deleting a message, is also reflected in your Gmail interface on the web (and vice versa).
Note that with IMAP, incoming email can take up to 15 minutes to be delivered to the BlackBerry, Gmail labels don't appear on the BlackBerry®, and conversation threads appear as individual messages.

What each user should do

  1. Make sure you've enabled IMAP in your Gmail account.
  2. On your BlackBerry®, navigate to your home screen.
  3. Select the icon that lets you set up email (this can be called Setup, Setup Wizard, Email Setup, BlackBerry® Set-up, E-mail settings, or Personal Email Set-up).
  4. Follow the setup instructions provided on your device to create a new email account.
  5. Be sure to enter the following:
    • Mail Server: imap.gmail.com
    • Username: [your full Gmail address ([email protected]]
    • Password: [your Google Apps password]
    • IMAP Port: 993
  6. Allow the system to add your account, but do not enter your Google Apps password into the utility boxes (this causes the system to default to POP3 instead of IMAP).
  7. Select Next.
  8. Select Next again (bypassing the Additional Information Required section).
  9. Select your account type, and then select Next. You may encounter a "We were unable to configure..." error. If so, select I will provide the settings to continue.
  10. Select the option that mentions IMAP/POP.
  11. Select I will provide the settings..., and then select Next.
  12. Select Set up existing email account...
  13. Enter your Gmail account information here, with imap.gmail.com as your mail server.
  14. Select Next.
  15. Select Save.
When setup is successful, you receive a confirmation message, and a new mailbox icon (labeled with your Gmail address) appears on your BlackBerry®'s home screen.

Google Apps Connector for BlackBerry® Enterprise Server

If you have a Blackberry® Enterprise Server at your organization and want to keep using it to manage users' BlackBerry® devices, no problem. Just use Google Apps Connector for BlackBerry® Enterprise Server. With Google Apps Connector, people in your organization can keep using their built-in BlackBerry® apps to access their Google Apps email, calendar, and contacts. And administrators can keep using use your BlackBerry® Enterprise Server to manage these devices (doing remote wipes, policy management, and so on).

How to use Google Apps Connector for your domain

  1. Download Google Apps Connector.
  2. Install and set up Google Apps Connector on your BlackBerry® Enterprise Server.
  3. Have each user follow these instructions to set up their BlackBerry® to connect to Google Apps.
When you're done, click Next and we'll move on to the next step.

Gmail Apps: Delivered on Multiple Computers

Do you access Gmail messages on two or more computers via POP clients like Outlook or Thunderbird. The problem (or advantage) with POP access is that once an email message gets downloaded onto one computer, it is skipped by other email clients.

To explain that further – let’s say you have configured both your personal laptop and work computer to download emails from your Gmail account via POP access. Now if the emails are downloaded to the laptop first, they wont be available on your work computer (and vice-versa).

While this is a time-saving feature, your emails are split across different computers. To trick your POP client into downloading Gmail emails that are already fetched by other clients, just use the recent mode in Gmail.

Solution A:
Open your Outlook (or other POP client) and add the word “recent:” to your gmail username. That means if your gmail address is “[email protected]” replace that with “recent:[email protected]

NOTE: This trick will also work on custom domains if you are using Google Apps with Gmail.

Solution B:
Use IMAP. POP3 isn't the only mail protocol in the world. If your mail service supports the Internet Message Access Protocol (IMAP), you can set up your client to use that. Rather than simply downloading, IMAP syncs your local client inbox with the one on your email service's server. That way, every computer or phone you check your mail with, provided you set up IMAP on all of them, sees the same messages.

NOTE: This would requires you to recreate the account in IMAP
