How Good Website Design Can Help You To Gain Visibility
How Good Website Design Can Help You To Gain Visibility
With the increasing competition in the online market there are so many options available for the customers that if the website design is not attractive and not clear then the visitors will not think twice about switching to a different site. Poor website design is the primary reason why most websites fail in attracting potential visitors.

If your website is lacking an attracting factor then here are some essentials that you can include in your website design

• Clarity of the site:
The ultimate goal of a website owner should be designing a user friendly and attractive design and this is not possible if the website lacks the clarity factor. The website should be designed in such a manner that it is easy for the visitors to understand and at the same time be pleasing to the eye. The clarity of the text and colouring should be handled effectively so that the visitor does not feel it is annoying and stay back from going through the products and services offered.

• Appropriate spacing:
Some of the websites are so clumsy that it is difficult to differentiate between the topics and understand the actual content. This scenario occurs when things are not presented in a proper manner and there is no spacing between different contents. There should be proper line spacing, padding and white spaces between the texts so that it is clearly understandable by the users.

• Proper navigation:
The main thing that frustrates the visitors is when they are unable to identify where they are and how to get where they want to be. This usually occurs when there is no proper navigation system for the website. Therefore it is essential that the website provides proper navigation facilities between their webpages so that the visitor is not confused and can easily identify the required details.

• Precedence:
Precedence is considered as the most important factor for any good web design. The visual prudence plays a vital role in deciding the look and feel of the website. The different factors that are considered important for the website design are size, background colours, the positioning of text and images, contrast and design elements.

If a website is designed including all the above mentioned factors then it will surely be successful in attracting good traffic and driving good traffic. If you face any difficulty in designing the website then you can take the help of digital media agency experts and if you do not have the funds you can take loans for bad debit which are short-term loans which give you cash instantly and help you meet your necessities.

PHP Fatal error: Allowed memory size of X bytes exhausted (tried to allocate Y) in file.php

1. memory_limit globally from php.ini
memory_limit = 64M

2. memory_limit using .htaccess
php_value memory_limit 64M

3. memory_limit inside a php script.
ini_set(‘memory_limit’, ’64M’);

To change the memory limit for one specific script by including a line such as this at the top of the script:

ini_set("memory_limit","64M");

The 12M sets the limit to 64 megabytes. If this doesn’t work, keep increasing the memory limit until your script fits.

You can change permanently for all PHP scripts running on the server by adding a line to the server’s php.ini file:

memory_limit = 64M

Keep in mind that a huge memory limit is a poor substitute for good coding. Some applications like data scrappers are run infrequently and require lots of memory like importing and processing a big data file using RSS, XML, JSON API etc.

Make sure each time script required server memory resources; need to release them when script/process finish first iteration to save memory uses 😉

PHP function might help….

1. unset — Unset a given variable

2. memory_get_usage — Returns the amount of memory allocated to PHP

3. memory_get_peak_usage — Returns the peak of memory allocated by PHP

4. __destruct your object references upon disposing of an object

5. The Alternative PHP Cache (APC) is a free and open opcode cache for PHP. Its goal is to provide a free, open, and robust framework for caching and optimizing PHP intermediate code.

6. Turn PHP scripts into Linux daemons

7. Xdebug’s Profiler is a powerful tool that gives you the ability to analyze your PHP code and determine bottlenecks or generally see which parts of your code are slow and could use a speed boost.


<?php
class Memory
{
public $var='3.1415962654';
}

$baseMemory = memory_get_usage();

for($i=0;$i<=100000;$i++)
{
$a=new Memory;
$a->self=$a;
if($i%500===0)
{
echo sprintf('%8d: ',$i), memory_get_usage() - $baseMemory,"\n";

Rackspace Cloud Load Balancers vs. Amazon Elastic Load Balancing


Hits: 5646  
Rackspace Cloud Load Balancers Amazon Elastic Load Balancing
Support Chat/phone/ticket support available 24x7x365 To receive 24x7x365 support for Amazon EC2, you pay the greater of $400 per month.
Dedicated Public IP Address A dedicated IP address allows for use as a root record for a zone. When you create an ELB instance, you get a public DNS name; however, it’s not very user friendly and you will want to create a CNAME record in DNS to redirect to your URL.
Access Control List (ACL) Rackspace cloud load balancer has an ACL-based security model. Access control list feature is not available.
Connection Logging Logs are sorted, aggregated, and delivered hourly to Cloud Files™, which is perfect for users who need to perform tuning, inspection, or analysis. Connection logging feature is not available.
Connection Throttling Rackspace cloud load balancers have a connection throttling feature which imposes limits on the number of connections per IP address. Connection throttling feature is not available.
Selectable Algorithms Customize the behavior of your cloud load balancer with selectable algorithms, including: random, round robin, weighted round robin, least connections, and weighted least connections. ELB utilizes only a non-configurable round robin load balancing algorithm.
Advanced HTTP Health Monitoring Rackspace Cloud Load Balancers can use synthetic transaction monitoring to inspect an HTTP response code and body content to ensure the application or site is healthy. While HTTP and TCP-based health monitors are available, ELB does not permit users to define an acceptable status code or body regular expression to match against.
Shared IPs Shared IPs facilitates easier management and better IP utilization of load balancer configuration. ELB does not permit users to share a single IP address across multiple load balancers, but does allow for a single load balancer to support multiple port configurations.
Internal Virtual IPs Internal virtual IPs feature allows you to load balance internal services, without being penalized with external bandwidth charges. All ELBs are configured as public virtual IPs. An internal virtual IP option is not available.
SSL Termination Does not support SSL termination at the load balancer. Supports SSL termination at the load balancer.

EC2 instance using Amazon SQS queues


Hits: 4338  

Amazon Simple Queue Service (Amazon SQS) offers a reliable, highly scalable, hosted queue for storing messages. Amazon SQS can be used to applications that perform different tasks, without losing messages. Amazon SQS enables users to build an automated workflow.

Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. Amazon EC2 can be used for building applications that start small but can scale up rapidly as demand increases (Auto Scaling).

Amazon EC2 Features:

a) Increase or decrease capacity within minutes.
b) Make one, hundreds, or even thousands of server instances simultaneously.
c) Web Service API to control the scaling of instances depending on needs.
d) Pay only for what you use (Pay Per Use) pricing model.

SQS

Features of Amazon SQS:

a) Single Amazon SQS queue can be shared by multiple servers simultaneously.
b) Server that is processing a message can prevent other servers from processing the same message at the same time using temporarily “locking” a message. The server can specify the amount of time the message is locked. When the server is done processing the message, it should delete the message. If the server fails while processing the message, another server can get the message after the lockout period.

AWS-SQS-EC2-S3

Pipeline processing with Amazon SQS:

Pipeline processing with Amazon SQS

a) Flexibility: Large monolithic server can be divided into multiple smaller servers without impacting the current system.

b) Piecemeal upgrades: Individual sub-components can be taken offline / upgraded without bringing the entire system down.

c) Tolerance to failures: Amazon SQS isolates sub-components from each other so the failure of one component does not impact the rest.
